IN one of the most beautiful of all the shining pages of his His- tory of the Spanish Conquest in America, Sir Arthur Helps describes the way in which, through " some fitness of the season, whether in great scientific discoveries or in the breaking into light of some great moral cause, the same processes are going on in many minds, and it seems as if they communicated with each other invisibly. We may imagine that all good powers aid the ' new light/ and brave and wise thoughts about it float aloft in the atmosphere of thought as downy seeds are borne over the fruitful face of the earth " (vol. iii, page 113). The thinker who elaborates a new system of philosophy deeper and more compre- hensive than any yet known to mankind, though he may work in solitude, nevertheless does not work alone. The very fact which makes his great scheme of thought a success and not a failure is the fact that it puts into definite and coherent shape the ideas which many people are more or less vaguely and loosely entertaining, and that it carries to a grand and triumphant con- clusion processes of reasoning in which many persons have al- ready begun taking the earlier steps. This community in mental trend between the immortal discoverer and many of the brightest contemporary minds, far from diminishing the originality of his work, constitutes the feature of it which makes it a permanent acquisition for mankind, and distinguishes it from the eccentric philosophies which now and then come up to startle the world for a while, and are presently discarded and forgotten.

And so it has been with the greatest achievement of modern thinking — the doctrine of evolution. Students and investigators in all de- partments, alike in the physical and in the historical sciences, were fairly driven by the nature of the phenomena before them into some hypothesis, more or less vague, of gradual and orderly change or development. The world was ready and waiting for Herbert Spencer's mighty work when it came, and it was for that reason that it was so quickly triumphant over the old order of thought. The victory has been so thorough, swift, and decisive that it will take another generation to narrate the story of it so as to do it full justice. Meanwhile, people's minds are apt to be somewhat dazed with the rapidity and wholesale character of the change ; and nothing is more common than to see them adopting Mr. Spencer's ideas without recognizing them as his or knowing whence they got them. As fast as Mr. Spencer could set forth his generalizations they were taken hold of here and there by special workers, each in his own department, and utilized therein. His general system was at once seized, assimilated, and set forth with new illustrations by serious thinkers who were already groping in the regions of abstruse thought which the master's vision pierced so clearly. And thus the doctrine of evolution has come to be inseparably interfused with the whole mass of think- ing in our day and generation. I do not mean to imply that peo- ple commonly entertain very clear ideas about it, for clear ideas are not altogether common. I suspect that a good many people would hesitate if asked to state exactly what Newton's law of gravitation is. Among the men in America whose minds, between thirty and forty years ago, were feeling their way toward some such unified conception of nature as Mr. Spencer was about to set forth in all its dazzling glory — among the men who were thus prepared to grasp the doctrine of evolution at once and expound it with fresh illustrations — the first in the field was the man to whose memory we have met here this evening to pay a brief word of tribute. It is but a little while since that noble face was here with us and the tones of that kindly voice were fraught with good cheer for us. To most of you, I presume, the man Edward Livingston Youmans is still a familiar presence. There must be many here this even- ing who listened to the tidings of his death two years ago with a sense of personal bereavement. No one who knew him is likely ever to forget him. But for those who remember distinctly the man it may not be superfluous to recount the principal in- EDWARD LIVINGSTON YOUMANS. 3 cidents of his life and work. It is desirable that the story should be set forth concisely, so as to be remembered ; for the work was like the man, unselfish and unobtrusive, and in the hurry and complication of modern life such work is liable to be lost from sight, so that people profit by it without knowing that such work was ever done. So genuinely modest, so utterly desti- tute of self -regarding impulses was our friend, that I believe it would be quite like him to chide us for thus drawing public at- tention to him, as he would think, with too much emphasis. But such mild reproof it is right that we should disregard ; for the memory of a life so beautiful and useful is a precious possession of which mankind ought not to be deprived. Edward Livingston Youmans was born in the town of Coeymans, Albany County, N. Y., on the 3d of June, 1821. From his father and mother, both of whom survived him, he inherited strong traits of character as well as an immense fund of vital energy, such that the failure of health a few years ago seemed (to me, at least) surprising. His father, Vincent Youmans, was a man of independent character, strong convictions, and perfect moral courage, with a quick and ready tongue, in the use of which earnestness and frankness perhaps sometimes prevailed over pru- dence. The mother, Catherine Scofield, was notable for balance of judgment, prudence, and tact. The mother's grandfather was Irish ; and, while I very much doubt the soundness of the gener- alizations we are so prone to make about race characteristics, I can not but feel that for the impulsive — one had almost said ex- plosive — warmth of sympathy, the enchanting grace and vivacity of manner, in Edward Youmans, this strain of Irish blood may have been to some extent accountable. Both father and mother belonged to the old Puritan stock of New England, and the fa- ther's ancestry was doubtless purely English. Nothing could be more honorably or characteristically English than the name. In the old feudal society the yeoman, like the franklin, was the small freeholder, owning a modest estate yet holding it by no servile tenure, a man of the common people yet no churl, a member of the state who "knew his rights and knowing dared maintain." Few indeed were the nooks and corners outside of merry England where such men flourished as the yeomen and franklins who founded democratic New England. It has often been remarked how the most illustrious of Franklins exemplified the typical virtues of his class. There was much that was similar in the tem- perament and disposition of Edward Youmans — the sagacity and penetration, the broad common sense, the earnest purpose veiled but not hidden by the blithe humor, the devotion to ends of wide practical value, the habit of making in the best sense the most out of life. 4 THE POPULAR SCIENCE MONTHLY. When Edward was but six months old, his parents moved to Greenfield, near Saratoga Springs. With a comfortable house and three acres of land, his father kept a wagon-shop and smithy. In those days, while it was hard work to wring a subsistence out of the soil or to prosper upon any of the vocations which rural life permitted, there was doubtless more independence of charac- ter and real shiftiness than in our time, when cities and tariffs have so sapped the strength of the farming country. In the fam- ily of Vincent Youmans, though rigid economy was practiced, books were reckoned to a certain extent among the necessaries of life, and the house was one in which neighbors were fond of gath- ering to discuss questions of politics or theology, social reform or improvements in agriculture. On all such questions Vincent Youmans was apt to have ideas of his own ; he talked with enthu- siasm, and was also ready to listen ; and he evidently supplied an intellectual stimulus to the whole community. For a boy of bright and inquisitive mind listening to such talk is no mean source of education. It often goes much further than the reading of books. From an early age Edward Youmans seems to have appropriated all such means of instruction. He had that insa- tiable thirst for knowledge which is one of God's best gifts to man ; for he who is born with this appetite must needs be griev- ously ill-made in other respects if it does not constrain him to lead a happy and useful life. After ten years at Greenfield the family moved to a farm at Milton, some two miles distant. Until his sixteenth year Edward helped his father at farm-work in the summer and attended the district school in winter. It was his good fortune for some time to fall into the hands of a teacher who had a genius for teaching — a man who in those days of rote-learning did not care to have things learned by heart, but sought to stimulate the thinking powers of his pupils, and who in that age of canes and ferules never found it necessary to use such means of discipline, because the fear of displeasing him was of itself all-sufficient. Experience of the methods of such a man was enough to sharpen one's dis- gust for the excessive mechanism, the rigid and stupid manner of teaching, which characterize the ordinary school. In after-years Youmans used to say that " Uncle Good " — as this admirable ped- agogue was called — first taught him what his mind was for. Through intercourse and training of this sort he learned to doubt, to test the soundness of opinions, to make original inquiries, and to find and follow clews. But even the best of teachers can effect but little unless he finds a mind ready of itself to take the initiative. It is doubtful if men of eminent ability are ever made so by schooling. The school offers opportunities, but in such men the tendency to the EDWARD LIVINGSTON YOUMANS. 5 initiative is so strong that if opportunities are not offered they will somehow contrive to create them. When Edward Yonmans was about thirteen years old he persuaded his father to buy him a copy of Comstock's Natural Philosophy. This book he studied at home by himself, and repeated many of the experiments with apparatus of his own contriving. "When he made a centrifugal water-wheel, and explained to the men and boys of the neighbor- hood the principle of its revolution in a direction opposite to that of the stream which moved it, we may regard it as his earliest at- tempt at giving scientific lectures. It was natural that one who had become interested in physics should wish to study chemistry. The teacher (who was not " Uncle Good ") had never so much as laid eyes on a text-book of chemistry ; but Edward was not to be daunted by such trifles. A copy of Comstock's manual was pro- cured, another pupil was found willing to join in the study, and this class of two proceeded to learn what they could from reading the book, while the teacher asked them the printed questions — those questions the mere existence of which in text-books is apt to show what a low view publishers take of the average intelligence of teachers ! It was not a very hopeful way of studying such a subject as chemistry ; but doubtless the time was not wasted, and the foundations for a future knowledge of chemistry were laid. The experience of farm-work which accompanied these studies ex- plains the interest which in later years Mr. Youmans felt in agri- cultural chemistry. He came to realize how crude and primitive are our methods of making the earth yield its produce, and it was his opinion that, when men have once learned how to conduct agriculture upon sound scientific principles, farming will become at once the most wholesome and the most attractive form of human industry. Along with the elementary studies in science there went a great deal of miscellaneous reading, mostly, it would appear, of good solid books. Apparently there was at that time no study of languages, ancient or modern. At the age of seventeen the young man had shown so much promise that it was decided he should study law, and he had already entered upon a more extensive course of preparation in an academy in Saratoga County when the event occurred which changed the whole course of his life. He had been naturally gifted with keen and accurate vision, was a good sportsman and an excellent shot with a rifle, but at about the age of thirteen there had come an attack of ophthalmia which left the eyes weak and sensitive. Perpetual reading probably in- creased the difficulty and hindered complete recovery. At the age of seventeen violent inflammation set in, the sight in one eye was completely lost, while in the other it grew so dim as to be of little avail. Sometimes he would be just able to find his way about the 6 THE POPULAR SCIENCE MONTHLY. streets, at other times the blindness was almost total, and this state of things lasted for nearly thirteen years. This dreadful calamity seemed to make it impossible to con- tinue any systematic course of study, and the outlook for satis- factory work of any sort was extremely discouraging. The first necessity was medical assistance, and in quest of this Mr. You- mans came in the autumn of 1839 to New York, where for the most part he spent the remainder of his life. Until 1851 he was under the care of an oculist. Under such circumstances, if a man of eager energy and boundless intellectual craving were to be overwhelmed with despondency, we could not call it strange. If he were to become dependent upon friends for the means of sup- port, it would be ungracious if not unjust to blame him. But Edward Youmans was not made of the stuff that acquiesces in defeat. He rose superior to calamity, he won the means of liveli- hood, and in darkness entered upon the path to an enviable fame. At first he had to resign himself to spending weary weeks over tasks that with sound eye-sight could have been dispatched in as many days. He invented some kind of writing-machine which held his paper firmly and enabled his pen to follow straight lines at proper distances apart. Long practice of this sort gave his hand- writing a peculiar character which it retained in later years. When I first saw it in 1863 it seemed almost undecipherable ; but that was far from being the case, and, after I had grown used to it, I found it but little less legible than the most beautiful chi- rography. The strokes, gnarled and jagged as they were, had a method in their madness, and every pithy sentence went straight as an arrow to its mark. While conquering these physical obstacles Mr. Youmans began writing for the press, and gradually entered into relations with leading newspapers which became more and more important and useful as years went on. He became acquainted with Horace Greeley, William Henry Channing, and other gentlemen who were interested in social reforms. His sympathies were strongly enlisted with the little party of abolitionists, then held in such scornful disfavor by all other parties. He was also interested in the party of temperance, which, as he and others were afterward to learn, compounded for its essential uprightness of purpose by indulging in very gross intemperance of speech and action. The disinterestedness which always characterized him was illustrated by his writing many articles for a temperance paper which could not afford to pay its contributors, although he was struggling with such disadvantages in earning his own livelihood and carry- ing on his scientific studies. Those were days when leading re- formers believed that by some cunningly contrived alteration of social arrangements our human nature, with all its inheritance EDWARD LIVINGSTON YOUMANS. 7 from countless ages of brutality, can somehow be made over all in a moment, just as one would go to work with masons and car- penters and revamp a house. There are many good people who still labor under such a delusion. Though Mr. Youmans was brought into frequent contact with reformers of this sort, it does not seem to me that his mind was ever deeply impressed with such ways of thinking. Science is teaching us that the method of evolution is that mill of God, of which we have heard, which, while it grinds with infinite efficacy, yet grinds with wearisome slowness. It was Mr. Darwin's dis- covery of natural selection which first brought this truth home to us ; but Sir Charles Lyell had in 1830 shown how enormous effects are wrought by the cumulative action of slight and unob- trusive causes, and this had much to do with turning men's minds toward some conception of evolution. It was about 1847 that Mr. Youmans was deeply interested in the work of geologists, as well as in the nebular theory, to which recent discoveries were adding fresh confirmation. Some time before this he had read that fa- mous book, Vestiges of Creation, and, although Prof. Agassiz truly declared that it was an unscientific book crammed with antiquated and exploded fancies, I suspect that Mr. Youmans felt that amid all the chaff there was a very sound and sturdy kernel of truth. Among the books which Mr. Youmans projected at this time, the first was a compendious history of progress in discovery and invention ; but, after he had made extensive preparations, a book was published so similar in scope and treatment that he abandoned the undertaking. Another work was a treatise on arithmetic, on a new and philosophical plan ; but, when this was approaching completion, he again found himself anticipated, this time by the book of Horace Mann. This was discouraging enough, but a third venture resulted in brilliant success. We have observed the eagerness with which, as a school-boy, Mr. Youmans entered upon the study of chemistry. His interest in this science grew with years, and he devoted himself to it so far as was practicable. For a blind man to carry on the study of a science which is pre- eminently one of observation and experiment might seem hope- less. It was at any rate absolutely necessary to see with the eyes of others if not with his own. Here the assistance rendered by his sister was invaluable. During most of this period she served as amanuensis and reader for him. But, more than this, she kept up for some time a course of laboratory work, the results of which were minutely described to her brother and discussed with him in the evenings. The lectures of Dr. John William Draper on chemistry were also thoroughly discussed and pon- dered. The conditions under which Mr. Youmans worked made it 8 THE POPULAR SCIENCE MONTHLY. necessary for him to consider every point with the extreme de- liberation involved in framing distinct mental images of things and processes which he conld not watch with the eye. It was hard discipline, but he doubtless profited from it. Nature had endowed him with an unusually clear head, but this enforced method must have made it still clearer. One of the most notable qualities of his mind was the absolute luminousness with which he saw things and the relations among things. It was this quality that made him so successful as an expounder of scientific truths. In the course of his pondering over chemical facts which he was obliged to take at second hand, it occurred to him that most of the pupils in common schools who studied chemistry were practi- cally no better off. It was easy enough for schools to buy text- books, but difficult for them to provide laboratories and appara- tus ; and it was much easier withal to find teachers who could ask questions out of a book than those who could use apparatus if provided. It was customary, therefore, to learn chemistry by rote ; or, in other words, pupils' heads were crammed with unin- telligible statements about things with queer names — such as manganese or tellurium — which they had never seen, and would not know if they were to see them. It occurred to Mr. Youmans that, if visible processes could not be brought before pupils, at any rate the fundamental conceptions of chemistry might be made clear by means of diagrams. He began devising diagrams in dif- ferent colors, to illustrate the diversity in the atomic weights of the principal elements, and the composition of the more familiar compounds. At length, by uniting his diagrams, he obtained a comprehensive chart exhibiting the outlines of the whole scheme of chemical combination according to the binary or dualist theory then in vogue. This chart, when published, was a great success. It not only facilitated the acquirement of clear ideas, but it was suggestive of new ideas. It proved very popular, and kept the field until the binary theory was overthrown by the modern doc- trine of substitution, which does not lend itself so readily to graphic treatment. The success of the chemical chart led to the writing of a text- book of chemistry. This laborious work was completed in 1851, when Mr. Youmans was thirty years old. Prof. Silliman was then regarded as one of our foremost authorities in chemistry, but it was at once remarked of the new book that it showed quite as thorough a mastery of the whole subject of chemical combina- tion as Silliman's. It was a text-book of a kind far less common then than now. There was nothing dry about it. The subject was presented with beautiful clearness, in a most attractive style. There was a firm grasp of the philosophical principles underlying chemical phenomena, and the meaning and functions of the sci- EDWARD LIVINGSTON YOUMANS. 9 ence were set forth, in such a way as to charm the student and make him wish for more. The book had an immediate and signal success ; in after-years it was twice rewritten by the au- thor, to accommodate it to the rapid advances made by the sci- ence, and it is still one of our best text-books of chemistry. It has had a sale of about one hundred and fifty thousand copies. The publication of this book at once established its author's reputation as a scientific writer, and in another way it marked an era in his life. The long, distressing period of darkness now came to an end. Sight was so far recovered in one eye that it became possible to go about freely, to read, to recognize friends, to travel, and make much, of life. I am told that his face had acquired an expression characteristic of the blind, but that expression was afterward completely lost. When I knew. him it would never have occurred to me that his sight was imperfect, except perhaps as regards length of range. Mr. Youmans's career as a scientific lecturer now began. His first lecture was the beginning of a series on the relations of organic life to the atmosphere. It was illustrated with chemical apparatus, and was given in a private room in New York to an audience which filled the room. Probably no lecturer ever faced his first audience without some trepidation, and Mr. Youmans had not the main-stay and refuge afforded by a manuscript, for his sight was never good enough to make such an aid available for his lectures. At first the right words were slow in finding their way to those ready lips, and his friends were beginning to grow anxious, when all at once a happy accident broke the spell. He was remarking upon the characteristic instability of nitrogen, and pointing to a jar of that gas on the table before him, when some fidgety movement of his knocked the jar off the table. He improved the occasion with one of his quaint bons mots, and, as there is nothing that greases the wheels of life like a laugh, the lecture went on to a successful close. This was the beginning of a busy career of seventeen years of lecturing, ending in 18G8 ; and I believe it is safe to say that few things were done in all those years of more vital and lasting benefit to the American people than this broadcast sowing of the seeds of scientific thought in the lectures of Edward Youmans. They came just at the time when the world was ripe for the doc- trine of evolution, when all the wondrous significance of the trend of scientific discovery since Newton's time was beginning to burst upon men's minds. The work of Lyell in geology, fol- lowed at length, in 1859 by the Darwinian theory ; the doctrine of the correlation of forces and the consequent unity of nature ; the extension and reformation of chemical theory ; the simultaneous advance made in sociological inquiry, and in the conception of the io THE POPULAR SCIENCE MONTHLY. true aims and proper methods of education — all this made the period a most fruitful one for the peculiar work of such a teacher as Youmans. The intellectual atmosphere was charged with con- ceptions of evolution. Mr. Youmans had arrived at such concep- tions in the course of his study of the separate lines of scientific speculation which were now about to be summed up and organ- ized by Herbert Spencer into that system of philosophy which marks the highest point to which the progressive intelligence of mankind has yet attained. In the field of scientific generaliza- tion upon this great scale, Mr. Youmans was not an originator ; but his broadly sympathetic and luminous mind moved on a plane so near to that of the originators that he seized at once upon the grand scheme of thought as it was developed, made it his own, and brought to its interpretation and diffusion such a happy combination of qualities as one seldom meets with. The ordinary popularizer of great and novel truths is a man who comprehends them but partially and illustrates them in a lame and fragmentary way. But it was the peculiarity of Mr. You- mans that, while on the one hand he could grasp the newest sci- entific thought so surely and firmly that he seemed to have en- tered into the innermost mind of its author, on the other hand he could speak to the general public in a convincing and stimulat- ing way that had no parallel. This was the secret of his power, and there can be no question that his influence in educating the American people to receive the doctrine of evolution was great and wide-spread. The years when Mr. Youmans was traveling and lecturing were the years when the old lyceum system of popular lectures was still in its vigor. The kind of life led by the energetic lect- urer in those days was not that of a Sybarite, as may be seen from a passage in one of his letters : " I lectured in Sandusky, and had to get up at five o'clock to reach Elyria ; I had had but very little sleep. To get from Elyria to Pittsburg I must take the five o'clock morning train, and the hotel darkey said he would try to awaken me. I knew what that meant, and so did not get a single wink of sleep that night. Rode all day to Pittsburg, and had to lecture in the great Academy of Music over foot-lights. . . . The train that left for Zanesville departed at two in the morning. I had been assured a hundred times (for I asked everybody I met) that I would get a sleeping-car to Zanesville, and, when I was all ready to start, I was informed that this morning there was no sleeping-car. By the time I reached here I was pretty completely used up." Such a fatiguing life, however, has its compensations. It brings the lecturer into friendly contact with the brightest minds among his fellow-countrymen in many and many places, and en- EDWARD LIVINGSTON YOUMANS. n larges his sphere of influence in a way that is not easy to estimate. Clearly an earnest lecturer, of commanding intelligence and charming manner, with a great subject to teach, must have an op- portunity for sowing seeds that will presently ripen in a change of opinion or sentiment, in an altered way of looking at things on the part of whole communities. No lecturer has ever had a better opportunity of this sort than Edward Youmans, and none ever made a better use of his opportunity. His gifts as a talker were of the highest order. The commonest and plainest story, as told by Edward Youmans, had all the breathless interest of the most thrilling romance. Absolutely unconscious of himself, sim- ple, straightforward, and vehement, wrapped up in his subject, the very embodiment of faith and enthusiasm, of heartiness and good cheer, it was delightful to hear him. . And when we join with all this his unfailing common sense, his broad and kindly view of men and things, and the delicious humor that kept flash- ing out in quaint, pithy phrases such as no other man would have thought of, and such as are the despair of any one trying to remember and quote them, we can seem to imagine what a power he must have been with his lectures. When such a man goes about for seventeen years, teaching scientific truths for which the world is ripe, we may be sure that his work is great, albeit we have no standard whereby we can exactly measure it. In hundreds of little towns with queer names did this strong personality appear and make its way and leave its effects in the shape of new thoughts, new questions, and enlarged hospitality of mind, among the inhabitants. The results of all this are surely visible to-day. In no part of the English world has Herbert Spencer's philosophy met with such a general and cordial reception as in the United States. This may, no doubt, be largely explained by a reference to general causes ; but as it is almost always necessary, along with our general causes, to take into the account some personal influence, so it is in this case. It is safe to say that among the agencies which during the past fifty years have so remarkably broadened the mind of the Ameri- can people, very few have been more potent than the gentle and subtle but pervasive work done by Edward Youmans with his lectures, and to this has been largely due the hospitable reception of Herbert Spencer's ideas. It was in 1856 that Mr. Youmans fell in with a review of Spen- cer's Principles of Psychology, by Dr. Morell, in the Medico- Chirurgical Review. This review impressed him so deeply that he at once sent to London for a copy of the book, which had been published in the preceding year. It will be observed that this was four years before the Darwinian theory was announced to the world in the first edition of the Origin of Species. Toward the 12 THE POPULAR SCIENCE MONTHLY. end of that book Mr. Darwin looked forward to a distant future when the conception of gradual development might be applied to the phenomena of conscious intelligence. He had not then learned of the existence of such a book as the Principles of Psy- chology. In later editions he was obliged to modify his state- ment and confess that, instead of looking so far forward, he had better have looked about him. I have more than once heard Mr. Darwin laugh merrily over this, at his own expense. After struggling for a while with the weighty problems of this book — the most profound treatise upon mental phenomena that any human mind has ever produced — Mr. Youmans saw that the theory expounded in it was a long stride in the direction of a gen- eral theory of evolution. His interest in this subject received a new and fresh stimulus. He read Social Statics, and began to recognize Mr. Spencer's hand in the anonymous articles in the quarterlies in which he was then announcing and illustrating various portions or segments of his newly discovered law of evolution. One evening in February, 1860, as Mr. Youmans was calling at a friend's house in Brooklyn, the Rev. Samuel Johnson, of Salem, h%nded him the famous prospectus of the great series of philosophical works which Mr. Spencer proposed to issue by subscription. Mr. Johnson had obtained this from Edward Sils- bee, who was one of the very first Americans to become interested in Spencer. The very next day Mr. Youmans wrote a letter to Mr. Spencer, offering his aid in procuring American subscriptions and otherwise aiding in every possible way the progress of the enterprise. With this letter and Mr. Spencer's cordial reply be- gan the life-long friendship between the two men. It was in that same month that I first became aware of Mr. Spencer's existence, through a single paragraph quoted from him by Mr. Lewes, and in that paragraph there was immense fascination. I had been steeping myself in the literature of modern philosophy, starting with Bacon and Descartes, and was then studying Comte's Phi- losophic Positive, which interested me as suggesting that the spe- cial doctrines of the several sciences might be organized into a general body of doctrine of universal significance. Comte's work was crude and often wildly absurd, but there was much in it that was very suggestive. In May, 1860, in the Old Corner Bookstore in Boston, I fell upon a copy of that same prospectus of Mr. Spen- cer's works, and read it with exulting delight, for clearly there was to be such an organization of scientific doctrine as the world was waiting for. It appeared that there was some talk of Tick- nor & Fields undertaking to conduct the series in case subscrip- tions enough should be received. Mr. Spencer preferred to have his works appear in Boston ; but when in the course of 1860 his book on Education was offered to Ticknor & Fields, they declined EDWARD LIVINGSTON YOUMANS. 13 to publish, it, which, was, of course, a grave mistake from the business point of view. Mr. Youmans, however, was not sorry for this, for it gave him the opportunity to place Mr. Spencer's books where he could do most to forward their success. Some years before, during his blindness, his sister had led him one day into the store of Messrs. D. Appleton & Co. in quest of a book, and Mr. William H. Appleton had become warmly inter- ested in him. I believe the firm now look back to this chance visit as one of the most auspicious events in their annals. He became by degrees a kind of adviser as regarded matters of publi- cation, and it was largely through his far-sighted advice that the Appletons entered upon the publication of such books as those of Buckle, Darwin, Huxley, Tyndall, Haeckel, and others of like character, always paying a royalty to the authors, the same as to American authors, in spite of the absence of an international copyright law. As publishers of books of this sort the Appletons have come to be pre-eminent. It is obvious enough nowadays that such books are profitable from a business point of view. But thirty years and more ago this was by no means obvious. We were very provincial. Reprints of English books, transla- tions from French and German, were sadly behind the times. In the Connecticut town where I lived people would begin to wake up to the existence of some great European book or system of thought after it had been before the world anywhere from a dozen to fifty years. In those days, therefore, it required some boldness to undertake the reprinting of new scientific books, and none have recognized more freely than the Appletons the impor- tance of the part played by Mr. Youmans in this matter. His work as adviser to a great publishing house and his work as lecturer re-enforced each other, and thus his capacity for useful- ness was much increased. When Mr. Spencer's book on Education failed to find favor in Boston, the Appletons took it, and thus presently secured the management of the philosophical series. This brought Mr. Youmans into permanent relations with Mr. Spencer and his work. In 1861 Mr. Youmans was married, and in the course of the following year made a journey in Europe with his wife. It was now that he became personally acquainted with Mr. Spencer, and found him quite as interesting and admirable as his books. Friendships were also begun with Huxley and other foremost men of science. From more than one of these men I have heard the warmest expressions of personal affection for Mr. Youmans, and of keen appreciation of the aid that they have obtained in innumerable ways from his intelligent and enthusiastic sympa- thy. But no one else got so large a measure of this support as Mr. Spencer. As fast as his books were republished, Mr. Youmans i 4 THE POPULAR SCIEXCE MONTHLY. wrote reviews of theni, and by no. means in the nsnal perfunctory way ; liis reviews and notices were turned ont by the score, and scattered abont in the magazines and newspapers where they would do the most good. Whenever he found another writer who could be pressed into the service, he would give him Spencer's books, kindle him with a spark from his own magnificent enthu- siasm, and set him to writing for the press. The most indefati- gable vender of wares was never more ruthlessly persistent in ad- vertising for lucre's sake than Edward Youmans in preaching in a spirit of the purest disinterestedness the gospel of evolution. As long as he lived, Mr. Spencer had upon this side of the Atlantic an alter ego ever on the alert with vision like that of a hawk for the slightest chance to promote his interests and those of his sys- tem of thought. Among the allies thus enlisted at that early time were Mr. George Ripley and Rev. Henry Ward Beecher, both of whom did good service, in their different ways, in awakening public interest in the doctrine of evolution. In those days of the civil war it was especially hard to keep up the list of subscribers in an abstruse philosophical publication of apparently interminable length. Mr. Youmans now and then found it needful to make a journey in the interests of the work, and it was on one of these occasions, in Xovember, 1SG3, that I made his acquaintance. I had already published, in 1861, an article in one of the quarterly reviews in which Mr. Spencer's work was referred to ; and another in 1863, in which the law of evolution was illustrated in connection with certain problems of the science of language. The articles were anonymous, as was then the fashion, and Mr. Youmans's curi- osity was aroused. There were so few people then who had any conception of what Mr. Spencer's work meant, that they could have been counted on one's fingers. At that time I knew of only three — the late Prof. Gurney, of Harvard ; Mr. George Roberts, now an eminent patent lawyer in Boston ; and Mr. John Clark, now of the Prang Educational Company. I have since known that there were at least two or three others about Boston, among others, my learned friend the Rev. W. R. Alger, besides several in other parts of the country. "When we sometimes ventured to observe that Mr. Spencers work was as great as Xewton's, and that his theory of evolution was going to remodel human thinking upon all subjects whatever, people used to stare at us and take us for idiots. Anv one member of such a small communitv was easv to find ; and I have always dated a new era in my life from the Sun- dav afternoon when Mr. Youmans came to my room in Cam- bridge. It was the beginning of a friendship such as hardly comes but once to a man. At that first meeting I knew nothing of him except that he was the author of a text-book of chemistry EDWARD LIVINGSTON YOUMANS. 15 which I had found interesting, in spite of its having been crammed down my throat by an old-fashioned memorizing teach- er who, I am convinced, never really knew so much as the differ- ence between oxygen and antimony. At first it was a matter of breathless interest to talk with a man who had seen Herbert Spencer. But one of the immediate results of this interview was the beginning of my own correspondence with Mr. Spencer, which led to manifold results. And from that time forth it always seemed as if, whenever any of the good or lovely things of life came to my lot, somehow or other Edward Youmans was either the cause of it or at any rate intimately concerned with it. The sphere of his unselfish goodness was so wide and its quality so potent that one could not come into near relations with him without becoming in all manner of unsuspected ways strengthened and enriched. In the autumn of i860 we were dismayed by the announce- ment that Mr. Spencer would no longer be able to go on issuing his works. In London they were published at his own expense and risk, and those books which now yield a handsome profit did not then pay the cost of making them. By the summer of 1865 there was a balance of £1,100 against Mr. Spencer, and his prop- erty was too small to admit of his going on and losing at such a rate. As soon as this was known, John Stuart Mill begged to be allowed to assume the entire pecuniary responsibility of continu- ing the publication ; but this, Mr. Spencer, while deeply affected by such noble sympathy, would not hear of. He consented, how- ever, with great reluctance, to the attempt of Huxley and Lub- bock, and other friends, to increase artificially the list of sub- scribers by inducing people to take the work just in order to help support it. But after several months the sudden death of Mr. Spencer's father added something to his means of support, and he thereupon withdrew his consent to this arrangement, and deter- mined to go on publishing as before, and bearing the loss. But, as soon as the first evil tidings reached America, Mr. You- mans made up his mind that 85,500 must be forthwith raised by subscription, in order to make good the loss already incurred. It is delightful to remember the vigor with which he took hold of this work. The sum of 87,000 was raised and invested in American securities in Mr. Spencer's name. If he did not see fit to accept these securities, they would go without an owner. The best Wal- tham watch that could be procured was presented to Mr. Spencer by his American friends ; a letter, worded with rare delicacy and tact, was written by the late Robert Minturn ; and Mr. Youmans sailed for England to convey the letter and the watch to Mr. Spencer. It was a charming scene on a summer day in an Eng- lish garden when the great philosopher was apprised of what had 16 THE POPULAR SCIENCE MONTHLY. been done. It was so skillfully managed that lie could not refuse the tribute without seeming churlish. He therefore accepted it, and applied it to extending his researches in descriptive sociology. Of the many visits which Mr. Youmans made to England, now and then extending them to the Continent, one of the most impor- tant was in 1871, for the purpose of establishing the International Scientific Series. This was a favorite scheme of Mr. Youmans. He realized that popular scientific books, adapted to the general reader, are apt to be written by third-rate men who do not well understand their subject ; they are apt to be dry or superficial or both. No one can write so good a popular book as the master of a subject, if he only has a fair gift of expressing himself and keeps in mind the public for which he is writing. The master knows what to tell and what to omit, and can thus tell much in a short com- pass and still make it interesting ; moreover, he avoids the inaccu- racies which are sure to occur in second-hand work. Masters of subjects are apt, however, to be too much occupied with original research to write popular books. It was Mr. Youmans's plan to induce the leading men of science in Europe and America to con- tribute small volumes on their special subjects to a series to be published simultaneously in several countries and languages. Furthermore, by special contract with publishing houses of high reputation, the author was to receive the ordinary royalty on every copy of his book sold in every one of the countries in ques- tion, thus anticipating international copyright upon a very wide scale, and giving the author a much more adequate compensation for his labor. To put this scheme into operation was a task of great difficulty, so many conflicting interests had to be consid- ered. Mr. Youmans's brilliant success is attested by that noble series of more than fifty volumes, on all sorts of scientific sub- jects, written by men of real eminence, and published in England, France, Italy, Germany, and Russia, as well as in the United States. A word is all that can be spared for other parts of our friend's work, which deserve many words and those carefully considered. His book on Household Science is not the usual collection of scrappy comment, recipe, and apothegm, but a valuable scien- tific treatise on heat, light, air, and food in their relations to every- day life. In his Correlation of Physical Forces he brings together the epoch-making essays of the men who have successively estab- lished that doctrine, introducing them with an essay of his own in which its history and its philosophical implications are set forth in a masterly manner. In his book on the Culture demanded by Modern Life we have a similar collection of essays with a simi- lar excellent original discussion, showing the need for wider and later training in science, and protesting against the excess of time EDWARD LIVINGSTON YOUMANS. i 7 and energy that is spent in classical education where it is merely the following of an old tradition. As a crown to all this useful work Mr. Youmans established, in 1872, The Popular Science Monthly, which has unquestionably been of high educational value to the general public. It was not the aim of this magazine to give an account of every theory ex- pounded, every fact observed, every discovery made from year to year, whether significant or insignificant. The mind of the peo- ple is not educated by dumping a great, unshapely mass of facts into it. It needs to be stimulated rather than crammed. Educa- tion in science should lead one to think for one's self. The scien- tific magazine, therefore, should present articles from all quarters that deal with the essential conceptions of science or discuss prob- lems of real theoretical or practical interest, no matter whether every particular asteroid or the last new species of barnacle re- ceives full attention or not. The Popular Science Monthly has now been with us eighteen years ; its character has always been of the highest, and it must have exerted an excellent influence not only as a diff user of valuable knowledge, but in training its readers to scientific habits of thought in so far as mere reading can con- tribute to such a result. In concluding our survey of this useful and noble life, what impresses us most, I think, is the broad, democratic spirit and the absolute unselfishness which it reveals at every moment and in every act. To Edward Youmans the imperative need for edu- cating the great mass of the people so as to use their mental powers to the best advantage came home as a living, ever-present fact. He saw all that it meant and means in the raising of man- kind to a higher level of thought and action than that upon which they now live. To this end he consecrated himself with unalloyed devotion ; and we who mourn his loss look back upon his noble career with a sense of victory, knowing how the good that such a man does lives after him and can never die. [Mr. Fiske's address was followed by appreciative remarks from several gentlemen who had known Mr. Youmans, and who gave many interesting reminiscences of him. We append a letter from Mr. Spencer, which arrived too late to be read at this meeting.] 64 Avenue Road, Regent's Park, London, N. W., March 13, 1890. Dear Mr. Skilton : I received your telegram last night, and from the wording conclude that you wish some letter from me about Youmans which Fiske may read in his lecture on the 23d. I am very glad to respond to the request, and I can not do this better than by giving you the following copy of a passage in my Auto- biography concerning him : "The relation thus initiated was extremely fortunate; for TOL. XXXTII. — 2 18 THE POPULAR SCIENCE MONTHLY. Prof. Edward L. Youmans was, of all Americans I have known or heard of, the one most able and most willing to help me. Alike intellectually and morally, he had in the highest degrees the traits conducive to success in diffusing the doctrines he es- poused ; and from that time to this he has devoted his life mainly to spreading throughout the United States the doctrine of evolution. His love of wide generalizations had been shown years before in lectures on such topics as the correlation of the physical forces ; and from those who heard him I have gathered that, aided by his unusual powers of exposition, the enthusiasm which contemplation of the larger truths of science produced in him was in a remarkable degree communicated to his hearers. Such larger truths I have on many occasions observed are those which he quickly seizes — ever passing at once through details to lay hold of essentials ; and, having laid hold of them, he clearly sets them forth afresh in his own way with added illus- trations. But it is morally even more than intellectually that he has proved himself a true missionary of advanced ideas. Extremely energetic — so energetic that no one has been able to check his overactivity — he has expended all his powers in ad- vancing what he holds to be the truth ; and not only his powers but his means. It has proved impossible to prevent him from in- juring himself in health by his exertions ; and it has proved im- possible to make him pay due regard to his personal interests. So that toward the close of life he finds himself wrecked in body and impoverished in estate by thirty years of devotion to high ends. Among professed worshipers of humanity, who teach that human welfare should be the dominant aim, I have not yet heard of one whose sacrifices on behalf of humanity will bear comparison with those of my friend." Though the volume containing this passage will not be pub- lished until after my death, I am very willing that this tribute of admiration to my late friend should be made public now. I am, faithfully yours, Herbert Spencer. A committee of the British Association is charged with the collection of infor- mation respecting the disappearance or threatened disappearance of rare plants. While instances of complete extinction of any species within recent times may be rare, there are more of local extinction or of apparent extinction for a time, and the cases of threatened extinction are numerous enough to he alarming. A potent factor in the changes that have taken place is " the injudicious action of botanists themselves, and of botanical exchange clubs. The 'dealer' and 'collector' also figure largely in the process, while tourists are not responsible for much damage except indirectly by patronizing dealers. It is too often forgotten that the very rarity of a plant is the sign, and in great degree also the measure, of the acuteness of its struggle for existence, and that, when a plant is in unstable equilibrium with its environment, a small disturbance may have di?proportionately great effects." ON JUSTICE. 19 ON JUSTICE. By HERBERT SPENCER. TN" the January number of this Review* (page 126), I made L-L the incidental statement that "should I be able to complete Part IV of the Principles of Ethics, treating of Justice, of which the first chapters only are at present written, I hope to deal ade- quately with these relations between the ethics of the progressive condition and the ethics of that condition which is the goal of progress — a goal ever to be recognized, though it can not be actu- ally reached." These chapters were written nearly a year ago : the fourth, not quite finished, having been untouched since May last. In view of the possibility that the division of which they form part may never be completed, or otherwise that its comple- tion may be long delayed, it has occurred to me that as the topic dealt with is now being discussed, these first chapters may, per- haps with advantage, be published forthwith. The editor having kindly assented to my proposal to issue them in this Review, I here append the first three : reserving two others, conveniently separable in subject-matter, for another article.] I. Animal-Ethics. — Those who have not read the first division of this work f will be surprised by the above title. But the chap- ters on Conduct in General and The Evolution of Conduct will have shown to those who have read them that something which may be regarded as animal-ethics is implied. It was there shown that the conduct which Ethics treats of is not separable from conduct at large ; that the highest conduct is that which conduces to the greatest length, breadth, and complete- ness of life ; and that by implication there is a conduct proper to each species of animal, which is the relatively good conduct — a conduct which stands toward that species as the conduct we mor- ally approve stands toward the human species. Most people regard the subject-matter of Ethics as being conduct considered as calling forth approbation or reprobation. But the primary subject-matter of Ethics is conduct considered objectively as producing good or bad results to self or others or both. Even those who think of Ethics as concerned only with con- duct which deserves praise or blame, tacitly recognize an animal- ethics ; for certain acts of animals excite in them antipathy or sympathy. A bird which feeds its mate while she is sitting is re- garded with a sentiment of approval. For a hen which refuses to * Nineteenth Century ; also Popular Science Monthly for March, page 616. f Reference is here made to the Data of Ethics. 20 THE POPULAR SCIENCE MONTHLY. sit upon her eggs there is a feeling of aversion ; while one which fights in defense of her chickens is admired. Egoistic acts, as well as altruistic acts, in animals are classed as good or bad. A squirrel which lays up a store of food for the winter is thought of as doing that which a squirrel ought to do ; and, contrariwise, one which idly makes no provision and dies of starvation, is thought of as properly paying the penalty of im- providence. A dog which surrenders its bone to another without a struggle, and runs away, we call a coward — a word of repro- bation. Thus then it is clear that acts which are conducive to preser- vation of offspring or of the individual we consider as good rela- tively to the species, and conversely. The two classes of cases of altruistic and egoistic acts of ani- mals just given, exemplify the two cardinal and opposed principles of animal-ethics. During immaturity benefits received must be inversely propor- tionate to capacities possessed. Within the family-group most must be given where least is deserved, if desert is measured by worth. Contrariwise, after maturity is reached, benefits must vary directly as worth : worth being measured by fitness to the conditions of existence. The ill fitted must suffer the evils of un- fitness, and the well fitted profit by their fitness. These are the two laws which a species must conform to if it is to be preserved. Limiting the proposition to the higher types (for in the lower types, parents give to offspring no other aid than that of laying up a small amount of nutriment with the germ ; the result being that an enormous mortality has to be balanced by an enormous fertility) — thus limiting the proposition, I say, it is clear that if, among the young, benefit were proportioned to effi- ciency, the species would disappear forthwith ; and if, among adults, benefit were proportioned to inefficiency, the species would disappear by decay in a few generations (see Principles of Soci- ology, section 322). What is the ethical aspect of these principles ? In the first place, animal life of all but the lowest kinds has been maintained by virtue of them. Excluding the Protozoa, among which their operation is scarcely discernible, we see that without gratis bene- fits to offspring, and earned benefits to adults, life could not have continued. In the second place, by virtue of them life has gradually evolved into higher forms. By care of offspring which has be- come greater with advancing organization, and by survival of the fittest in the competition among adults which has become keener OJST JUSTICE. 21 with, advancing organization, superiority -has been perpetually fos- tered, and further advances caused. On the other hand, it is true that to this self-sacrificing care for the young and this struggle for existence among adults, has been due the carnage and the death by starvation which have characterized the evolution of life from the beginning. It is also true that the processes consequent on conformity to these prin- ciples are responsible for the production of torturing parasites, which outnumber in their kinds all other creatures. To those who take a pessimist view of animal-life in general, contemplation of these principles can of course yield only dissatis- faction. But to those who take an optimist view, or a meliorist view, of life in general, and who accept the postulate of hedonism, contemplation of these principles must yield greater or less satis- faction, and fulfillment of them must be ethically approved. Otherwise considered, these principles are either, according to the current belief, expressions of the Divine will, or, according to the agnostic belief, indicate the mode in which works the Unknow- able Power throughout the Universe ; and in either case they have the warrant hence derived. But here, leaving aside the ultimate controversy of pessimism versus optimism, it will suffice for present purposes to set out with a hypothetical postulate, and to limit it to a single species. If the preservation and prosperity of such species are to be de- sired, there inevitably emerge one most general conclusion and from it three less general conclusions. The most general conclusion is that, in order of obligation, the preservation of the species takes precedence of the preservation of the individual. It is true that the species has no existence save as an aggregate of individuals ; and it is true that, therefore, the wel- fare of the species is an end to be subserved only as subserving the welfares of individuals. But since disappearance of the species, implying disappearance of all individuals, involves absolute fail- ure in achieving the end, whereas disappearance of individuals, though carried to a great extent, may leave outstanding such number as can, by continuance of the species, make subsequent fulfillment of the end possible ; the preservation of the individual must, in a variable degree according to circumstances, be subordi- nated to the preservation of the species, where the two conflict. The resulting corollaries are these : First, that among adults there must be conformity to the law that benefits received shall be directly proportionate to merits pos- sessed : merits being measured by power of self-sustentation. For, otherwise, the species must suffer in two ways. It must suffer immediately by sacrifice of superior to inferior, which entails a 22 THE POPULAR SCIENCE MONTHLY. general diminution of welfare ; and it must suffer remotely by furthering increase of the inferior and, by implication, hindering increase of the superior, and by a consequent general deterioration which, if continued, must end in extinction. Second, that during early life, before self-sustentation has be- come possible, and also while it can be but partial, the aid given must be the greatest where the worth shown is the smallest — benefits received must be inversely proportionate to merits pos- sessed : merits being measured by power of self-sustentation. Unless there are gratis benefits to offspring, unqualified at first and afterward qualified by decrease as maturity is approached, the species must disappear by extinction of its young. There is, of course, necessitated a proportionate self-subordination of adults. Third, to this self-subordination entailed by parenthood has, in certain cases, to be added a further self -subordination. If the constitution of the species and its conditions of existence are such that sacrifices, partial or complete, of some of its individuals, so subserve the welfare of the species that its numbers are better maintained than they would otherwise be, then there results a justification for such sacrifices. Such are the laws by conformity to which a species is main- tained ; and if we assume that the preservation of a particular species is a desideratum, there arises in it an obligation to conform to these laws, which we may call, according to the case in ques- tion, quasi-ethical or ethical. II. Sub-Human Justice.— Of the two essential but opposed principles of action by pursuance of which each species is pre- served, we are here concerned only with the second. Passing over the law of the family as composed of adults and young, we have now to consider exclusively the law of the species as composed of adults only. This law we have seen to be that individuals of most worth, as measured by their fitness to the conditions of existence, shall have the greatest benefits, and that inferior individuals shall receive smaller benefits, or suffer greater evils, or both results — a law which, under its biological aspect, has for its implication the sur- vival of the fittest. Interpreted in ethical terms it is that each individual ought to be subject to the effects of its own nature and resulting conduct. Throughout sub-human life this law holds without qualification ; for there exists no agency by which, among adults, the relations between conduct and consequence can be in- terfered with. Fully to appreciate the import of this law we may with advan- tage pause a moment to contemplate an analogous law ; or, rather, the same law as exhibited in another sphere. Besides being dis- played in the relations among members of the species, as respect- ON JUSTICE. 23 ively well or ill sustained according to. their well-adapted activi- ties or ill-adapted activities, it is displayed in the relations of parts of each organism to one another. Every muscle, every viscus, every gland, receives blood in pro- portion to function. If it does little it is ill-fed and dwindles ; if it does much it is well-fed and grows. By this balancing of ex- penditure in action and payment in nutriment, there is, at the same time, a balancing of the relative powers of the parts of the organism ; so that the organism as a whole is fitted to its exist- ence by having the proportions of its parts continuously adjusted to the requirements. And clearly this principle of self -adjustment within each individual is parallel to that principle of self -adjust- ment by which the species as a whole keeps itself fitted to its en- vironment. For by the better nutrition and greater power of propagation which come to members of the species that have fac- ulties and consequent activities best adapted to the needs, joined with the lower sustentation of self and offspring which accompany less adapted faculties and activities, there is caused such special growth of the species as most conduces to its survival in face of surrounding conditions. This, then, is the law of sub-human justice, that each individual shall receive the benefits and the evils of its own nature and its consequent conduct. But sub-human justice is extremely imperfect, alike in general and in detail. In general, it is imperfect in the sense that there exist multitu- dinous species the sustentation of which depends on the wholesale destruction of other species ; and this wholesale destruction im- plies that the species serving as prey have the relations between conduct and consequence so habitually broken that in but very few individuals are they long maintained. It is true that in such cases the premature loss of life suffered from enemies by nearly all mem- bers of the species, must be considered as resulting from their na- tures — their inability to contend with the destructive agencies they are exposed to. But we may fitly recognize the truth that this vio- lent ending of the immense majority of its lives, implies that the species is one in which justice, as above conceived, is displayed in but small measure. Sub-human justice is extremely imperfect in detail, in the sense that the relation between conduct and consequence is in such an immense proportion of cases broken by accidents — accidents of kinds which fall indiscriminately upon inferior and superior in- dividuals. There are the multitudinous deaths caused by inclem- encies of weather, which, in the great majority of cases, the best members of the species are liable to like the worst. There are 24 THE POPULAR SCIENCE MONTHLY. otlier multitudinous deaths caused by scarcity of food, which, if not wholly, still in large measure, carries off good and bad alike. Among low types, too, enemies are causes of death which so oper- ate that superior as well as inferior are sacrificed. And the like holds with invasions by parasites, often widely fatal. These at- tack, and frequently destroy, the most perfect individuals as read- ily as the least perfect. The high rate of multiplication required to balance the immense mortality among low animals, at once shows us that among them long survival is not insured by superiority ; and that thus the sub- human justice, which consists in continued receipt of the results of conduct, holds individually in but few cases. And here we come upon a truth of great significance — the truth that sub-human justice becomes more decided as organization be- comes higher. Whether this or that fly is taken by a swallow, whether among a brood of caterpillars an ichneumon settles on this or that, whether out of a shoal of herrings this or that is swallowed by a cetacean, is an event quite independent of individual peculiarity : good and bad samples fare alike. With high types of creatures it is other- wise. Keen senses, sagacity, agility, give a particular carnivore special power to secure prey. In a herd of herbivorous creatures, the one with quickest hearing, clearest vision, most sensitive nos- tril, or greatest speed, is the one most likely to save itself. Evidently, in proportion as the endowments, mental and bodily, of a species are high, and as, consequently, its ability to deal with the incidents of the environment is great, the continued life of each individual is less dependent on accidents against which it can not guard. And, evidently, in proportion as this result of general superiority becomes marked, the results of special superiorities are felt. Individual differences of faculty play larger parts in determining individual fates. Now deficiency of a power short- ens life, and now a large endowment prolongs it. That is to say, individuals experience more fully the results of their own natures — the justice is more decided. • With creatures which lead solitary lives, the nature of sub- human justice is thus sufficiently expressed ; but on passing to gregarious creatures, there enters into it a new element. Simple association, as of sheep or deer, profits the individual and the species only by that more efficient safeguarding which results from the superiority of a multitude of eyes, ears, and noses over the eyes, ears, and nose of a single individual. Through the alarms niore quickly given, all benefit by the senses of the most acute. Where this, which we may call passive co-operation, rises ON JUSTICE. 25 into active co-operation, as among rooks where one of the flock keeps watch while the rest feed, or as among beavers where a number work together in making dams, or as among wolves where, by a plan of attack in which the individuals play different parts, prey is caught which would otherwise not be caught ; there is still greater advantage to the individuals and to the species. And, speaking generally, we may say that gregariousness, and co- operation more or less active establish themselves in a species only because they are profitable to it ; since, otherwise, survival of the fittest must prevent establishment of them. But now mark that this profitable association is made possible only by observance of certain conditions. The acts directed to self-sustentation which each performs, are performed more or less in presence of others performing like acts ; and there tends to re- sult more or less interference. If the interference is great, it may render the association unprofitable. For the association to be profitable the acts must be restrained to such an extent as to leave a balance of advantage. Survival of the fittest will else ex- terminate that variety of the species in which association begins. Here, then, we find a further factor in sub-human justice. Each individual, receiving the benefits and the injuries due to its own nature and consequent conduct, has to carry on that conduct subject to the restriction that it shall not in any large measure impede the conduct by which each other individual achieves bene- fits or brings on itself injuries. The average conduct must not involve aggressions of such amounts as to cause evils which out- balance the good obtained by co-operation. Thus, to the positive element in sub-human justice has to be added, among gregarious creatures, a negative element. The necessity for observance of the condition that each mem- ber of the group while carrying on the pursuit of self-sustentation and sustentation of offspring, shall not seriously impede the like pursuits of others, makes itself so felt, where association is estab- lished, as to mold the species to it. The mischiefs from time to time experienced when the limits are transgressed, continually discipline all in such ways as to produce regard for the limits ; so that such regard becomes, in course of time, a natural trait of the species. For, manifestly, regardlessness of the limits, if great and general, causes dissolution of the group. Those varieties only can survive as gregarious varieties in which there is an inherited tendency to maintain the limits. Yet, further, there arises such general consciousness of the need for maintaining the limits, that punishments are inflicted on transgressors — not only by aggrieved members of the group, but by the group as a whole. A " rogue " elephant (always distin- 26 THE POPULAR SCIENCE MONTHLY. guished as unusually malicious) is one which, has "been expelled from the herd : doubtless because of conduct obnoxious to the rest — probably aggressive. It is said that from a colony of beavers an idler is banished, and thus prevented from profiting by labors in which he does not join : a statement made more credible by the fact that drones, when no longer needed, are killed by worker- bees. The testimonies of observers in different countries show that a flock of crows, after prolonged noise of consultation, will summarily execute an offending member. And an eye-witness affirms that among rooks, a pair which steals the sticks from neighboring nests has its own nest pulled to pieces by the rest. Here, then, we see that the a priori condition to harmonious co-operation comes to be tacitly recognized as something like a law ; and there is a penalty consequent upon breach of it. That the individual shall experience all the consequences, good and evil, of its own nature and consequent conduct, which is that primary principle of sub-human justice whence results survival of the fittest, is, in creatures that lead solitary lives, a principle complicated only by the responsibilities of parenthood. Among them the purely egoistic actions of self-sustentation have, during the reproductive period, to be qualified by that self -subordination which the rearing of offspring necessitates, but by no other self- subordination. Among gregarious creatures of considerable in- telligence, however, the welfare of the species occasionally de- mands a further self -subordination. We read of bisons that, during the calving season, the bulls form an encircling guard around the herd of cows and calves, to protect them against wolves and other predatory animals : a proceeding which entails on each bull some danger, but which conduces to the preservation of the species. Out of a herd of elephants about to emerge from a forest to reach a drinking- place, one will first appear and look round in search of dangers, and, not discerning any, will then post some others of the herd to act as watchers; after which the main body comes forth and enters the water. Here a certain extra risk is run by the few that the many may be the safer. In a still greater degree we are shown this kind of action by a troop of monkeys, the members of which will combine to defend or rescue one of their number ; for though in any particular case the species may not profit, since more mortality may result than would have resulted, yet it profits in the long run by the display of a character which makes attack on its groups dangerous. Evidently, then, if by such conduct one variety of a gregarious species keeps up, or increases, its numbers, while other varieties, in which self -subordination thus directed does not exist, fail to do ON JUSTICE. 27 this, a certain sanction is acquired for -such conduct. The preser- vation of the species being the ultimate end, it results that where an occasional mortality of individuals in defense of the species furthers this preservation in a greater degree than would pursuit of exclusive benefit by each individual, that which we recognize as sub-human justice may rightly have this second limitation. It remains only to point out the order of priority, and the re- spective ranges, of these principles. The law of relation between conduct and consequence, which, throughout the animal kingdom at large, brings prosperity to those individuals which are struct- urally best adapted to their conditions of existence, and which, under its ethical aspect, is expressed in the principle that each individual ought to receive the good and the evil which arises from its own nature, is the primary law holding of all creatures ; and is applicable without qualification to creatures which lead solitary lives, save in that self-subordination needed among the higher of them for the rearing of offspring. Among gregarious creatures, and in an increasing degree as they co-operate more, there comes into play a law, second in order of time and authority, that those actions through which, in ful- fillment of its nature, the individual achieves benefits and avoids evils, shall be restrained by the need for non-interference with the like actions of associated individuals. A substantial respect for this law in the average of cases being the condition under which alone gregariousness can continue, it becomes an imperative law for creatures to which gregariousness is a benefit. But, obviously, this secondary law is simply a specification of that form which the primary law takes under the conditions of gregarious life ; since, by asserting that in each individual the interactions of conduct and consequence must be restricted in the specified way, it tacitly reasserts that these interactions must be maintained in all other individuals. Later in origin, and narrower in range, is the third law, that under conditions such that, by the occasional sacrifices of some members of a species, the species as a whole prospers, there arises a sanction for such sacrifices, and a consequent qualification of the law that each individual shall receive the benefits and evils of its own nature. Finally, it should be observed that whereas the first law is absolute for animals in general, and whereas the second law is absolute for gregarious animals, the third law is relative to the existence of enemies of such kinds that, in contending with them, the species gains more than it loses by the sacrifice of a few mem- bers ; and in the absence of such enemies this qualification im- posed by the third law disappears. 28 THE POPULAR SCIENCE MONTHLY. III. Human Justice. — The contents of the last chapter fore- shadow the contents of this. As, from the evolution point of view, human life must be regarded as a further development of sub-human life, it follows that from this same point of view, hu- man justice must be a further development of sub-human justice. For convenience the two are here separately treated, but they are essentially of the same nature, and form parts of a continuous whole. Of man, as of all inferior creatures, the law by conformity to which the species is preserved is that among adults the individu- als best adapted to the conditions of their existence shall prosper most, and that individuals least adapted to the conditions of their existence shall prosper least — a law which, if uninterfered with, entails survival of the fittest, and spread of the most adapted varieties. And as before so here, we see that, ethically consid- ered, this law implies that each individual ought to receive the benefits and the evils of his own nature and consequent conduct : neither being prevented from having whatever good his actions normally bring to him, nor allowed to shoulder off on to other persons whatever ill is brought to him by his actions. To what extent such ill, naturally following from his actions, may be voluntarily borne by other persons, it does not concern us now to inquire. The qualifying effects of pity, mercy, and gen- erosity, will be considered hereafter in the parts dealing with Xegative Beneficence and Positive Beneficence. Here we are con- cerned only with pure justice. The law thus originating, and thus ethically expressed, is ob- viously that which commends itself to the common apprehen- sion as just. Sayings and criticisms daily heard imply a percep- tion that conduct and consequence ought not to be dissociated. When, of some one who suffers a disaster, it is said — u He has no one to blame but himself/' there is implied the belief that he has not any ground for complaint. The comment on one whose mis- judgment or misbehavior has entailed evil upon him, that " he has made his own bed, and now he must lie in it," has behind it the conviction that this connection of cause and effect is proper. Similarly with the remark — " He got no more than he deserved." A kindred conviction is implied when, conversely, there results good instead of evil. " He has fairly earned his reward " ; " He has not received due recompense"; are remarks indicating the consciousness that there should be a proportion between effort put forth and advantage achieved. The truth that justice becomes more pronounced as organiza- tion becomes higher, which we contemplated in the last chapter, is further exemplified on passing from sub-human justice to ON JUSTICE. 29 human justice. The degree of justice and the degree of organi- zation simultaneously make advances. These are shown alike by the entire human race, and by its superior varieties as contrasted with its inferior. We saw that a high species of animals is distinguished from a low species in the respect that since its aggregate suffers less mor- tality from destructive agencies, each of its members continues on the average for a longer time subject to the normal relation be- tween conduct and consequence ; and here we see that the human race as a whole, far lower in its rate of mortality than nearly all races of inferior kinds, usually subjects its members for much longer periods to the good and evil results of well-adapted and ill-adapted conduct. We also saw that as, among the higher ani- mals, a greater average longevity makes it possible for individual differences to show their effects for longer periods, it results that the unlike fates of different individuals are to a greater extent determined by that normal relation between conduct and conse- quence which constitutes justice ; and we here see that in mankind unlikenesses of faculty in still greater degrees, and for still longer periods, work out their effects in advantaging the superior and disadvantaging the inferior in the continuous play of conduct and consequence. Similarly is it with the civilized varieties of mankind as com- pared with the savage varieties. A still further diminished rate of mortality implies that there is a relatively still larger propor- tion, the members of which, during long lives, gain good from well-adapted acts, and suffer evil from ill-adapted ones. While also it is manifest that both the greater differences of longevity among individuals, and the greater differences of social position, imply that in civilized societies more than in savage societies, dif- ferences of endowment and consequent differences of conduct are enabled to cause their appropriate differences of results, good or evil : the justice is greater. More clearly in the human race than in lower races are we shown that gregariousness establishes itself because it profits the variety in which it arises, partly by furthering general safety and partly by facilitating sustentation. And we are shown that the degree of gregariousness is determined by the degree in which it thus subserves the interests of the variety. For where the variety is one of which the members live on wild food, they associate only in small groups : game and fruits widely distributed can support these only. But greater gregariousness arises where agriculture makes possible the support of a large number on a small area ; and where the accompanying development of industries intro- duces many and various co-operations. 3 o THE POPULAR SCIENCE MONTHLY, But that which, was faintly indicated among lower beings is conspicuously displayed among human beings — that the advan- tages of co-operation can be had only by conformity to certain requirements which association imposes. The mutual hindrances liable to arise during the pursuit of their ends by individuals liv- ing in proximity, must be kept within such limits as to leave a surplus of advantage obtained by associated life. Some types of men, as the Abors, lead solitary lives, because their aggressiveness is such that they can not live together. And in view of this ex- treme case it is clear that though, in many primitive groups, indi- vidual antagonisms often cause quarrels, yet the groups are main- tained because their members derive a balance of benefit — chiefly in greater safety. It is also clear that in proportion as commu- nities become developed and their division of labor complex, the advantages of co-operation can be gained only by a still better maintenance of those limits to each man's activities necessitated by the simultaneous activities of others. This truth is illustrated by the unprosperous or decaying state of communities in which the aggressions of individuals on one another are so numerous and great as to prevent them from severally receiving the normal results of their actions. The requirement that individual activities must be mutually restrained, which we saw is so felt among certain inferior grega- rious creatures that they inflict punishments on those who do not duly restrain them, is a requirement which, more imperative among men, and more distinctly felt by them to be a require- ment, causes a still more marked habit of inflicting punishments on offenders. Though in primitive groups it is commonly left to any one who is injured to revenge himself on the injurer, and though even in the societies of feudal Europe, the defending and enforcing of his claims was in many cases held to be each man's personal concern ; yet there has ever tended to grow up such per- ception of the need for internal order, and such sentiment accom- panying the perception, that infliction of punishments by the com- munity as a whole, or by its established agents, has become habit- ual. And that a system of laws enacting restrictions on conduct, and punishments for breaking them, is a natural product of human life carried on under social conditions, is shown by the fact that among multitudinous nations composed of various types of man- kind, similar actions, similarly regarded as trespasses, have been similarly forbidden. Through all which sets of facts is manifested the truth, recog- nized practically if not theoretically, that each individual carrying on the actions which subserve his life, and not prevented from receiving their normal results good and bad, shall carry on these actions under such restraints as are imposed by the carrying on of ON JUSTICE. 3 i kindred actions by other individuals, who have similarly to receive such normal results good and bad. And vaguely, if not definitely, this is seen to constitute what is called justice. We saw that among inferior gregarious creatures, justice in its universal simple form, besides being qualified by the self-subordi- nation which parenthood implies, and in some measure by the self-restraint necessitated by association, is in a few cases further qualified in a small degree by the partial or complete sacrifice of individuals made in defense of the species. And now in the high- est gregarious creature we see that this further qualification of primitive justice assumes large proportions. No longer as among inferior beings demanded only by the need for defense against enemies of other kinds, this further self- subordination is, among human beings, also demanded by the need for defense against enemies of the same kind. Having be- come the predominant inhabitants of the Earth, and having spread wherever there is food, men have come to be everywhere in one another's way ; and the mutual enmities hence resulting, have made the sacrifices entailed by wars between groups, far greater than the sacrifices made in defense of the groups against inferior animals. It is doubtless true with the human race, as with lower races, that destruction of the group or the variety does not imply destruction of the species ; and it therefore follows that such obligation as exists for self-subordination in the inter- ests of the group or the variety, is an obligation of lower degree than is that of sustentation of offspring, without fulfillment of which the species must disappear, and of lower degree than the obligation to restrain actions within the limits imposed by social conditions, without fulfillment of which the group will dissolve. Still, it must be regarded as an obligation to the extent to which the maintenance of the species is subserved by the maintenance of each of its groups. But the self-subordination thus justified, and in a sense ren- dered obligatory, is limited to that which is required for defensive war. Only because the preservation of the group as a whole conduces to preservation of its members' lives and their ability to pursue the objects of life, is there a reason for the sacrifice of some of its members ; and this reason no longer exists when war is offensive instead of defensive. It may, indeed, be contended that since offensive wars initiate those struggles between groups which end in the destruction of the weaker, offensive wars, furthering the peopling of the Earth by the stronger, subserve the interests of the race. But even sup- posing that the conquered groups always consisted of men having smaller mental or bodily fitness for war (which they do not ; for 3 2 THE POPULAR SCIENCE MONTHLY. it is in part a question of numbers, and the smaller groups may consist of the more capable warriors), there would still be an adequate answer. It is only during the earlier stages of human progress that the development of strength, courage, and cunning, are of chief importance. After societies of considerable size have been formed and the subordination needed for organizing them produced, other and higher faculties become those of chief im- portance ; and the struggle for existence carried on by force, does not always further the survival of the fittest. The fact that but for a mere accident Persia would have conquered Greece, and the fact that the Tartar hordes very nearly overwhelmed European civilization, show that offensive war can be trusted to subserve the interests of the race only when the capacity for a high social life does not exist, and that in proportion as this capacity de- velops, offensive war tends more and more to hinder, rather than to further, human welfare. In brief we may say that the arrival at a stage in which ethical considerations come to be entertained, is the arrival at a stage in which offensive war, by no means cer- tain to further predominance of races fitted for a high social life, and certain to cause injurious moral reactions on the conquering as well as on the conquered, ceases to be justifiable; and only defensive war retains a quasi-ethical justification. And here it is to be remarked that the self-subordination which defensive war involves, and the need for such qualification of the abstract principle of justice as it implies, belong to that transitional state necessitated by the physical-force-conflict of races; and that they must disappear when there is reached a peaceful state. That is to say, all questions concerning the ex- tent of such qualifications pertain to what we distinguished as relative ethics ; and are not recognized by that absolute ethics which is concerned with the principles of right conduct in a society formed of human beings fully adapted to social life. This distinction I emphasize here because throughout succeed- ing chapters we shall find that recognition of it helps us to disentangle the involved problems of political ethics. — Nine- teenth Century. The constantly receding character of the unexplained was illustrated by Dr. Burdon Sanderson, in his address at the British Association, by reference to the discovery of the cell, which seemed to be a very close approach to the mechanism of life ; " but now we are striving to get even closer, with the same resnlt. Our measurements are more exact, our methods finer ; but these very methods bring us to close quarters with phenomena which, although within reach of exact inves- tigation, are, as regards their essence, involved in a mystery which is the more profound the more it is brought into contact with the exact knowledge we possess of surrounding conditions." SUMPTUARY LAWS AND THEIR SOCIAL INFLUENCE. 33 SUMPTUARY LAWS AND THEIR SOCIAL INFLUENCE.* By WILLIAM A. HAMMOND, M. D. THERE are many persons who have what they conceive to be the good of their fellow-creatures so greatly at heart that, when they can not succeed in making them conform to a standard of right and wrong that they have set up for themselves, endeavor to accomplish their object by legal enactments. It is true they are very apt to do this under the fiction of insuring the public welfare ; but it is none the less a fact, even if we admit the force of their alleged motive, that such laws as those to which I refer interfere with the personal liberty of those against whom they are aimed, and this to an extent incompatible with that degree of freedom of will and of action which is inseparable from the indi- vidual in all communities founded upon what we call liberty. Moreover, they are inquisitorial in their nature, and, what is per- haps a point of even still greater importance, they fail to accom- plish the object in view; and being continually evaded on one pretext or another, tend to diminish that respect for the majesty of law which all well-ordered citizens should entertain. The history of sumptuary laws, or laws tending to limit luxury and expense, shows how truly the remarks just made are founded on fact ; and yet in all ages of the world such laws have been passed, to be disobeyed, held in contempt, remaining on the statute- book unenforced, and finally either passing into oblivion or being formally repealed. As we are apparently passing through a stage of our national existence in which sumptuary laws are making their appearance, it seemed to me that the Society for Medical Jurisprudence and State Medicine might very properly have its attention directed to the subject. Among the first within our knowledge to provide by law for the regulation of the appetite, the taste, the affections, the dress, and the most minute details in the life of a citizen was Sparta, Sparta was a small country and its people were few ; they were surrounded by powerful neighbors. The first principle instilled into the mind of every individual was, that the state had a claim upon him superior to that of parents or of any relational or social bond. He was from the very cradle trained for war ; luxury, being regarded as incompatible with true manliness, was to be sup- pressed at all hazards. Foreigners, being liable to become a dis- turbing factor in the system of discipline enforced, were not allowed to enter Sparta ; even the feeble children, as being unfit * Read before the New York Society for Medical Jurisprudence and State Medicine, June 3, 1889. vol. xxxvii. — 3 34 THE POPULAR SCIENCE MONTHLY. for war and liable to become burdens on the community, were put to death. Gold and silver wer*e excluded, and the coinage was of iron. As far as possible the whole nation was fed alike. That the system was effectual in accomplishing the object that Lycur- gus had in view, is probably true. It succeeded just as persecu- tion succeeds when it is thorough and implacable. A half-hearted system of persecution not only fails in its object, but invariably advances the cause against which it is directed. If, for instance, we could kill all those who oppose us in our efforts to make mat- ters accord with our own way of thinking, we should undoubtedly be triumphantly successful ; but if we only killed a few of them, it would not be long before the number of the remainder would be so augmented that they would kill us. Nowhere has the inefficacy of sumptuary laws been more thoroughly demonstrated than in Rome. There the dress, the food, the furniture of the houses, were attempted to be regulated by law after law, which were either openly or secretly disobeyed, and which eventually disappeared from the statute-books. The cost of entertainments was limited ; the number of guests a person might have at his house was restricted. No woman was allowed to have more than half an ounce of gold, or to wear a dress of more than one color, or to ride in a carriage. In France, during the Celtic period, a law was passed that women should drink water only. In 1188 or thereabout no person was allowed to wear garments of vair, gray, zibeline, or scarlet color. No laced or slashed garments were allowed, and no one could have more than two courses at meals. In 1328 scarlet was only permitted to be worn by princes, knights, and women of high rank. The use of silver plate was prohibited except to certain high dignitaries ; and women were frequently sent to prison in forties, fifties, and sixties at a time for wearing clothes above their rank. Even as late as the seventeenth century gold, as an ornament on carriages, build- ings, and gloves, was prohibited. In England, during the reign of Edward IV, cloth of gold or silk of a purple color was prohibited to all but members of the royal family. Lords were allowed to wear velvet, knights satin, and esquires and gentlemen camelet. None but noblemen were allowed to wear woolen clothes made out of England, or fur of sables, and no laborer, servant, or artificer might wear any cloth which cost more than two shillings a yard. In the year 1336 an act of Parliament was passed which I quote in full, as showing to what extremes law can go in the way of interfering with the interior life of the citizens : " "Whereas heretofore, through the excessive and over-many sorts of costly meats which the people of this Realm have used more than elsewhere, many mischiefs have happened to the SUMPTUARY LAWS AND THEIR SOCIAL INFLUENCE. 35 people of this Realm : for the great men by these excesses have been sore grieved, and the lesser people who only endeavor to imitate the great ones in such sorts of meats are much impover- ished, whereby they are not able to aid themselves nor their liege lord in time of need as they ought, and many other evils have happened as well to their souls as to their bodies, our Lord the King, desiring the common profit as well of the great men as of the common people of his Realm, and considering the evils, griev- ances, and mischiefs aforesaid, by the common assent of the prel- ates, earls, barons, and other nobles of his said Realm and of the commons of the said Realm, hath ordained and established that no man, of what state or condition soever he be, shall cause himself to be served in his house or elsewhere, at dinner-meal or supper, or at any other time, with more than two courses and each mess of two sorts of victuals at the utmost, be it of flesh or fish, with the common sort of pottages without sauce or any other sort of victuals. And if any man choose to have sauce for his mess he may, provided it be not made at great cost ; and if flesh or fish be to be mixed therein it shall be of two sorts only at the utmost, either flesh or fish, and shall stand instead of a mess except only on the principal feasts of the year, on which days every man may be served with three courses at the utmost, after the manner aforesaid." But laws and proclamations were of no avail, though they continued to be issued and passed down to the reign of Queen Elizabeth ; and in the reign of James I all sumptuary laws were repealed. Since then the people of England have been allowed to wear, to eat, and to drink what they pleased. In our own country the experiment has been tried with as much thoroughness and with practically as little result as has attended the attempt by other nations. As early as the year 1639 we have the prototype of that curious law enacted a few years ago in the State of Iowa, which prohibits one person from invit- ing another to take a drink, or treating, as it is called. In the records of the colony of Massachusetts for the year mentioned we find as follows : " Forasmuch as it is evident unto this Court that the common custom of drinking one to another is a mere useless ceremony, and draweth on that abominable practice of drinking healths, and is also an occasion of much waste to the good creatures and of many other sins," such things are declared to be a reproach to a Christian commonwealth and are not to be tolerated. How- ever, invectives of the council appear to have been of little effect, notwithstanding the severity of the punishments which were meted out to those who infringed the laws. Drunkenness, which is at most only a vice, was made a crime ; and in 1636 one Peter 3 6 THE POPULAR SCIENCE MONTHLY. Bussaker was condemned for drunkenness to be whipped with twenty stripes well laid on. Robert Coles, for drunkenness com- mitted at Roxbury, was condemned to be disfranchised, and to wear about his neck so that it would hang upon his outward gar- ment a letter D, made of red cloth, and set upon white, to con- tinue this for a year, and not to leave it off at any time in public, under penalty of forty shillings for the first offense and five pounds for the second. Severity of punishments appeared only to aggravate the evil against which they were directed, for in 1648 the Court was forced to declare that " it is found by experi- ence that a great quantity of wine is spent and much thereof is abused to excess of drinking and unto drunkenness itself, not- withstanding all the wholesome laws provided and published for the preventing thereof." It therefore orders, with a blind per- versity which is a remarkable instance of the fatuity which actu- ates people when they endeavor to accomplish the impossible, that those who are authorized to sell wine and beer shall not har- bor a drunkard in their houses, but shall forthwith give him up to be dealt with by the proper officer, under penalty of five pounds for disobedience. Tobacco, for some cause or other, was especially obnoxious to the early colonial authorities of Massachusetts. The trade in the weed was only allowed to the old planters, but the sale or use of it was absolutely forbidden unless upon urgent occasion for the benefit of health and taken privately. It was also ordered that victualers or keepers of an ordinary shall not suffer any tobacco to be taken into their houses, under penalty of five shillings for every offense, to be paid by the victualer, and twelvepence by the person who takes it. Further, it was ordered that no person should take tobacco publicly, under the penalty of two shillings sixpence, nor privately in his own house or in the house of an- other before strangers ; and that two or more shall not take it together anywhere, under the aforesaid penalty for every offense. It is true these laws against the use of tobacco are not so severe as some that have been enacted in other countries, but they were equally inefficacious. Thus, a Sultan of Turkey issued an edict to the effect that any one of his subjects detected in the act of smoking should for the first offense have his cheeks bored and transfixed by his pipe ; for the second offense he was to have his nose cut off ; and for the third he was to lose his head. Fines in the case of the New-Englanders, and mutilation and death in the case of the Turks, have not in the slightest degree prevented the use of tobacco ; and that some recent laws to which I shall presently draw attention will prove equally futile there can be. no doubt. In all these instances of sumptuary laws the ground has been SUMPTUARY LAWS AND THEIR SOCIAL INFLUENCE. 37 taken that not only was the individual to be benefited, but that society as a whole was to be improved. Prohibitory laws relative to the manufacture and sale of alcoholic liquors which have been enacted in this country in our own times are based upon this assumption, but the arguments that have been used by those ad- vocating such laws show that this is not the only motive by which they are governed. It has been and still is repeatedly asserted in the speeches and writings of these people that those who indulge in alcoholic liquors or in the use of tobacco spend money which could otherwise be more profitably used, and that indulgence in the habit of drinking or smoking directly conduces to idleness and luxurious habits. These assertions are probably true, and the laws against which the practices in question are directed are essentially sumptuary laws. The laws which several States have enacted relative to the manufacture and sale of alcoholic liquors are true sumptuary laws, notwithstanding the fact that it is claimed by their adherents that they are measures which every independent State having a regard for the welfare of society is in duty bound to enforce. On that ground there are many other acknowledged evils against which the law-making power might very properly direct its energies, and which would interfere scarcely less with personal rights. One chief difficulty with such laws is that if thoroughly enforced, they do harm to those who never under any circumstances drink intoxi- cating liquors to excess, and yet who are benefited by their mod- erate use. As a matter of fact they never are enforced equally upon all classes of the community. In the most severe of all the States it is perfectly practicable for any person with pecuniary means to import as much alcoholic liquor for his own use and that of his family and friends as he chooses. The poor man, to whom a glass of beer or of wine taken decently and in order might not only do no harm, but might supply a positive want of his system, has to go without, or else resort to all kinds of deceit and subterfuge to get what he wants. States exceed their legiti- mate powers when they undertake to prevent a person doing that which is beneficial to him, and which does no harm to any one else. Moreover, as I have already said, such laws, being in this age of the world impossible of enforcement, tend to bring all law into contempt. It is not necessary for me to go into detail on this point ; every one who hears me knows how the prohibitory liquor laws of the various States that have passed them are dis- regarded and ridiculed. Every now and then we hear of some instance where an offender is arrested and punished, but for every one brought before the courts a thousand go unnoticed. In the States of Maine, Vermont, and Rhode Island I know from my own personal experience that, notwithstanding the stringent liquor 4 o THE POPULAR SCIENCE MONTHLY. indignant at being treated in so outrageous a manner, and utters his protest in no measured language ; his conduct only serves to convince his captors that the charge based upon the odor of alcohol is well founded, and he is mulcted in forty or sixty dollars, or sent to the workhouse for ninety days, as the case may be. No one is safe under such a law ; it is often a very difficult matter to determine whether a person is drunk or sober, and frequently it is impossible even by the most minute examination. Again, some people become intoxicated from a single glass of champagne, while others will drink two or more bottles with impunity. It is manifestly unjust to allow an individual peculiarity like this to establish the guilt or innocence of an accused person. As I have said, why stop at making drunkenness a crime when there are other vices far more immoral and more destructive to the character of the perpetrator ? Why not enact a law against lying ? There are laws against slander, which injures the one against whom it is directed, and they are well enough, for to injure another is a crime. But lying in the abstract remains unnoticed by the penal statutes, though a more degrading vice in the eyes of all civilized mankind than mere drunkenness. On the first of June of the year 1889 a statute went into effect in the State of New York which prohibits, under severe penal- ties, the selling of cigarettes to minors under the age of sixteen ; and the State of Michigan has recently not only enacted a similar law, but goes farther, and interdicts the manufacture of cigarettes within the limits of the State. Is it to be supposed for one mo- ment that minors under the age of sixteen in either State smoke fewer cigarettes than they did before these laws were passed ? How is the vender to know in many cases whether the applicant for cigarettes is over sixteen or not ? And is there any difficulty for any minor to get a companion who is undoubtedly over six- teen, or some one else, to buy cigarettes for him ? Legislatures, that pass such laws, and governors that sign them, are apparently ignorant of the first principles of jurisprudence. I venture to say that even now, although not two weeks have elapsed since the act went into effect, it is practically a dead letter in the city of New York and throughout the State generally, and I am quite sure that not a single conviction will ever be obtained under its pro- visions. I am not certain that our society did its full duty in not protesting against the statute-books being encumbered with such rubbish. Cigarette-smoking by minors is an evil to be sup- pressed by proper instruction and by the intervention of parents and guardians. If these latter can not prevent it, it is quite cer- tain that all the policemen in the State, backed by all the majesty of this particular law, will have their labor for their pains. THE STRENGTH OF SPIDERS AND SPIDER-WEBS. 41 THE STRENGTH OF SPIDERS AND SPIDER-WEBS.* By HENEY C. McCOOK, D. D. T IHE frailty of a spider's web has passed into a proverb. Yet, comparatively, the silken line of an orb-weaver is very strong. According to Schaffenberger, it requires ninety spinning threads of an Epe'ira to yield one thread of the thickness of a caterpillar's thread ; and, according to Leeuweiihoek, it requires eighteen thousand spider lines to make the thickness of a hair of the beard. These comparisons are suggestive, although in a meas- ure deceptive, since there are vast differences in the size of the threads woven by Epeiroids. It is probable that the extraordinary strength of the thread is due to the superposition of a large num- ber of extremely minute threads. However, after the thread is woven, Meckel could not recognize it as consisting of more than eight to ten strands. A geometric snare, whether vertical or hori- zontal, must be strong enough to sustain the weight of a spider of considerable size, such as Argiope cophinaria or Epe'ira insularis, particularly when the female is heavy with eggs. Blackwell thus determined by experiment the strength of a line by which a female Epe'ira diademata, weighing ten grains, had sustained itself from a twig : He attached to the extremity of the line a small piece of muslin with the corners nearly drawn together, so as to form a minute sack, into which he carefully introduced sixty-one grains' weight in succession, being more than six times the weight of the spider. On the addition of half a grain more the line broke. Not only must an orb sustain the weight and movements of its maker, but it must also have sufficient strength to hold the various insects which strike upon it. Bees and wasps are sometimes able to break through the spiral meshes of a large snare, but generally the threads are strong enough to hold them, in spite of their struggles, until the proprietor can enswathe them. Moreover, the orb-web must be able to sustain the weight of evening dews. One who has seen such snares in the early morning, when every viscid bead appears to have attracted to itself an incasing armor of sil- very dew, and has noticed how the spiral strings are bagged down under the weight of the same (Fig. 1), must have inferred that the snare was able to support a comparatively heavy burden. The same is true concerning summer showers, which must fall very heavily, and be driven before a pretty strong wind, in order to batter down a well-constructed orb-web. * Reprinted from Vol. I of American Spiders and their Spinning- Work, by the kind permission of the author, to whom we are also indebted for the accompanying illustrations. 4 o THE POPULAR SCIENCE MONTHLY. indignant at being treated in so outrageous a manner, and utters his protest in no measured language ; his conduct only serves to convince his captors that the charge based upon the odor of alcohol is well founded, and he is mulcted in forty or sixty dollars, or sent to the workhouse for ninety days, as the case may be.

And is there any difficulty for any minor to get a companion who is undoubtedly over six- teen, or some one else, to buy cigarettes for him ? Legislatures that pass such laws, and governors that sign them, are apparently ignorant of the first principles of jurisprudence. I venture to say that even now, although not two weeks have elapsed since the act went into effect, it is practically a dead letter in the city of New York and throughout the State generally, and I am quite sure that not a single conviction will ever be obtained under its pro- visions. I am not certain that our society did its full duty in not protesting against the statute-books being encumbered with such rubbish. Cigarette-smoking by minors is an evil to be sup- pressed by proper instruction and by the intervention of parents and guardians. If these latter can not prevent it, it is quite cer- tain that all the policemen in the State, backed by all the majesty of this particular law, will have their labor for their pains. THE STRENGTH OF SPIDERS AND SPIDER-WEBS. 41 THE STRENGTH OF SPIDERS AND SPIDER-WEBS.* By HENRY C. McCOOK, D. D. T IHE frailty of a spider's web has passed into a proverb. Yet, comparatively, the silken line of an orb-weaver is very strong. According to Schaffenberger, it requires ninety spinning threads of an Epeira to yield one thread of the thickness of a caterpillar's thread ; and, according to Leeuwenhoek, it requires eighteen thousand spider lines to make the thickness of a hair of the beard. These comparisons are suggestive, although in a meas- ure deceptive, since there are vast differences in the size of the threads woven by Epeiroids. It is probable that the extraordinary strength of the thread is due to the superposition of a large num- ber of extremely minute threads. However, after the thread is woven, Meckel could not recognize it as consisting of more than eight to ten strands. A geometric snare, whether vertical or hori- zontal, must be strong enough to sustain the weight of a spider of considerable size, such as Argiope cophinaria or Epeira insularis, particularly when the female is heavy with eggs. Blackwell thus determined by experiment the strength of a line by which a female Epeira diademata, weighing ten grains, had sustained itself from a twig : He attached to the extremity of the line a small piece of muslin with the corners nearly drawn together, so as to form a minute sack, into which he carefully introduced sixty-one grains' weight in succession, being more than six times the weight of the spider. On the addition of half a grain more the line broke. Not only must an orb sustain the weight and movements of its maker, but it must also have sufficient strength to hold the various insects which strike upon it. Bees and wasps are sometimes able to break through the spiral meshes of a large snare, but generally the threads are strong enough to hold them, in spite of their struggles, until the proprietor can enswathe them. Moreover, the orb-web must be able to sustain the weight of evening dews. One who has seen such snares in the early morning, when every viscid bead appears to have attracted to itself an incasing armor of sil- very dew, and has noticed how the spiral strings are bagged down under the weight of the same (Fig. 1), must have inferred that the snare was able to support a comparatively heavy burden. The same is true concerning summer showers, which must fall very heavily, and be driven before a pretty strong wind, in order to batter down a well-constructed orb-web. * Reprinted from Vol. I of American Spiders and their Spinning- Work, by the kind permission of the author, to whom we are also indebted for the accompanying illustrations. 4 2 THE POPULAR SCIENCE MONTHLY. An illustration of the remarkable strength and elasticity of the foundation lines of orb-webs appears in a biographical notice of the distinguished astronomer, the late General Ormsby M. Mitchell, printed with an edition of his lect- ures. Prof. Mitch- ell directed his great ingenuity to the problem of causing a clock to record its beats telegraphically, and at the same time perfectly per- form the work of a time - keeper. The required makes and breaks in the battery were effected by means of a cross of delicate wire and a mercury- cup. Many obsta- cles having been overcome, there arose the great difficulty of pro- curing a fiber suf- ficiently minute and elastic to con- stitute the physical union between the top stem of the cross and the clock pendulum. Various materials were tried, among others a delicate human hair, the very finest that could be ob- tained, but this was too coarse and stiff. Its want of pliancy and elasticity gave to the minute " wire cross " an irregular mo- tion, and caused it to rebound from the globule of mercury into which it should have plunged. " After many fruitless attempts," says Prof. Mitchell, " an appeal was made to an artisan of wonder- ful dexterity — the assistance of the spider was invoked ; his web, perfectly elastic and perfectly pliable, was furnished, and this material connection between the wire cross and the clock pendu- lum proved to be exactly the thing required. In proof of this remark I need only state the fact that one single spider's web has fulfilled the delicate duty of moving the wire cross, lifting it, and again permitting it to dip into the mercury every second of time Fig. 1.— Sector of a Dew-laden Orb-web. (Magnified.) THE STRENGTH OF SPIDERS AND SPIDER-WEBS. 43 for a period of more than three years ! How much longer it might have faithfully performed the same service I know not, as it then became necessary to break this admirable bond, to make some changes in the clock. Here it will be seen that the same web was expanded and contracted each second during the whole period, and yet never, so far as could be observed, lost any portion of its elasticity." At various times there have been placed on record accounts of the capture by spiders of small vertebrate animals, as snakes, mice, and birds. Popular stories to the same effect have from time to time been sent the rounds of the daily press, and found utterance and often illustration, the latter sometimes of a most original and remarkable character, in popular magazine literature. The great seeming disparity, in such cases, between the size and vigor of captive and prisoner ; the confusion of the various narratives in details as to the species and behavior of the spider, and the charac- teristics of her snare ; the radical departure from known food habit of species that are insectivorous ; together with the fact that the accounts all have come from lay observers, have been more or less lacking in scientific accuracy and minuteness of detail, and wholly without scientific verification — these considerations have caused such records and reports to be discredited by arachnologists and naturalists generally. But there are a few cases, confirmed by circumstantial evidence, and reported by observers of good reputation and careful habit, which deserve notice. The physical powers of the Lycosidce, the popular running, ground, or wolf spiders, are well illustrated by an instance recorded in the proceedings of the Academy of Natural Sciences of Phila- delphia. The result as reported was achieved by pure strength and activity, without any of the mechanical advantages of a snare. Mr. Spring, while walking with a friend in a swampy wood, which was pierced by a dike three feet wide, was attracted by the extraordinary movements of a large black spider in the middle of a ditch. Closer examination showed that the creature had caught a fish ! She had fastened upon it with a deadly grip just on the forward side of the dorsal fin, and the poor fish was swimming round and round slowly, or twisting its body as if in pain (Fig. 2). The head of its black enemy was sometimes almost pulled under water, but the strength of the fish would not permit an entire submersion. It moved its fins as if exhausted, and often rested. Finally it swam under a floating leaf near the shore and made a vain effort to dislodge the spider by scraping against the under side of the leaf. The two had now closely approached the bank. Suddenly the long black legs of the spider emerged from the water, and the hinder ones reached out and fastened upon the irregularities of 44 THE POPULAR SCIENCE MONTHLY. the sides of the ditch. The spider commenced tugging at his prize in order to land it. The observer ran to the nearest honse for a wide-mouthed bottle, leaving his friend to watch the strug- gle. During an interval of six or eight minutes' absence the spi- der had drawn the fish entirely out of the water ; then both creat- ures had fallen in again, the bank being nearly perpendicular. There followed a great struggle, and on Mr. Spring's return the fish was already hoisted head first more than half its length out upon the land. It was very much exhausted, hardly mak- ing any movement, and was being slowly and steadily drawn up by the spider, who had evidently gained the vic- tory. She had not once quit Fig. 2.— A Fish captured by a Dolomede Spider. her hold during the period of a quarter to half an hour of obser- vation. Her head was directed toward the fish's tail ; she stepped backward up an elevation of forty-five degrees, dragging her cap- tive with her. The observers were unfortunately unable to await the issue of the matter, and therefore caught the combatants in the bottle, partly filled with water. The fish swam languidly at the bottom of the vessel, and the spider stood sentinel on the surface, turning when the fish turned and watching every motion. The bottle was set aside and visited after an interval of three hours. The spider was then found dead at the bottom of the jar, but the fish was alive and lived twenty-four hours afterward. The spider was three fourths of an inch long and weighed fourteen grains; the fish was three and one fourth inches long and weighed sixty-six grains. The spider was probably bruised by the catching. THE STRENGTH OF SPIDERS AND SPIDER-WEBS. 45 One of the most remarkable records of the physical and me- chanical powers of spiders is made in Silliman's Journal. The ac- count is authenticated by the names and statements of a number of gentlemen resident in the vicinity of the occurrence, Batavia, N. Y. One evening Hon. David E. Evans found in his wine-cel- lar a live striped snake, nine inches long, suspended by the tail in a spider's web between two shelves. The snake hung so that its head could not reach the shelf below it by about an inch. The shelves were about two feet apart, and the lower one was just be- low the bottom of a cellar window, through which the snake prob- ably passed into it. From the upper shelf there hung a web in the shape of an inverted cone, eight or ten inches in diameter at the top, and concentrated to a focus about six or eight inches from the under side of this shelf. From this focus there was a strong cord made of the multiplied threads of the spider's web, appar- ently as large as sewing-silk, and by this cord the snake was sus- pended. A rude sketch of the serpent suspended in the web was made by an eye-witness, and is exactly repro- duced at Fig. 3. A close examination showed that the snake's mouth was entirely closed by a number of threads wound around it. Its tail was tied in a knot so as to leave a small loop or ring, through which the cord was fastened, as seen in the figure. Accepting the account as true, or at least probable, I would make the following inferences : First, the de- scription of the web, although suffi- ciently indefinite, leaves little doubt that the snake was originally taken in a snare of a species of tube-weaver, and most probably by the medicinal spider, Tegenaria medicinalis (Hentz). The broad-sheeted web of this spider is frequently found in cellars, which are favorite haunts. It builds near windows, in the angles and along the sides of walls, having its tubular den in a crack or opening laid along an angle (Fig. 4). The sheet is usually drawn upward until its exterior margin is higher than the plane of the entrance of the tube. There is thus formed a sort of pouch within which insects often fall, and so are readily captured by the spider, who mounts guard at the door of her den. Over the door the tube frequently rises into a sort of tower. I had often wished for an opportunity to follow up critically one of the recurring reports of the physical powers of spiders. Pig. 3. -A Snake entangled in a Spider's Web. 4 6 THE POPULAR SCIENCE MONTHLY. This wish was gratified in the summer of 1882. An article drifted through American newspapers which detailed the ensnaring of a living mouse by a Kentucky spider. I was fortunately able to trace the story to its origin in the Lebanon (Ky.) Standard and Times. Correspondence with its intelligent editor, Mr. J. W. Hop- Fig. 4. — The Pouch, Web, Tower, and Cocoon of the Medicinal Spider. per, brought me entire confirmation of the report from a number of trustworthy sources. I think the incident of sufficient impor- tance to justify a somewhat detailed presentation. The original account, as published by Mr. Hopper, is as follows : " A very curious and interesting spectacle was to be seen Monday afternoon in the office of Mr. P. C. Cleaver's livery-stable in this city. Against the wall of the room stands a tolerably tall desk, and under this a small spider, not larger than a common pea, had constructed an extensive web reaching to the floor (Fig. 5). About half past eleven o'clock Monday forenoon, it was observed that the spider had ensnared a young mouse by passing filaments of her web around its tail. When first seen, the mouse had its fore-feet on the floor, and could barely touch the floor with its hind-feet. The spider was full of business, running up and down the line and occasionally biting the mouse's tail, mak- ing it struggle desperately. Its efforts to escape were all un- availing, as the slender filaments about its tail were too strong THE STRENGTH OF SPIDERS AND SPIDER-WEBS. 47 for it to break. In a short time it was seen that the spider was slowly hoisting its victim into the air. By two o'clock in the afternoon the mouse could barely touch the floor with its fore- feet ; by dark the point of its nose was an inch above the floor. At nine o'clock at night the mouse was still alive, but made no sign except when the spider descend- ed and bit its tail. At this time it was an inch and a half from the floor. Yesterday morning the mouse was dead, and hung three inches from the floor. The news of the novel sight soon be- came circulated, and hun- dreds of people visited the stable to witness it. The mouse was a small one, measuring about an inch and a half from the point of its nose to the root of the tail." The space given the above facts may seem to ||| some to be in undue pro- portion to their impor- tance. But, apart from the value of positively determining any point in natural history, the dis- cussion has this conclusion : The capture of small vertebrate ani- mals by both sedentary and wandering spiders is possible; the one by the mechanical strength of their snares, the other by their physical strength. There is thus laid the foundation, at least, for the presumption that such animals may be or become natural food for the larger species of araneads. This is certainly a most important fact in the life-history of spiders, and would greatly enlarge the range of their habits. Fig. 5.— A Mouse hanging in a Spider's Snare. Me. F. J. Moss, of the New Zealand Legislature, and an extensive traveler in Polynesia, suggests that the deterioration of the natives of those regions may be partly due to faulty instruction. It is neither desirable nor expedient to thwart Na- ture too much. What is most needed, this author thinks, is to allow the islanders in their work and their amusements free scope for the imaginative powers with which they are endowed, and the exercise of which is too often foolishly discouraged. 48 THE POPULAR SCIENCE MONTHLY. SECONDARY SCHOOL PROGRAMMES— FRENCH AND AMERICAN. By GEOEGE W. BEAMAN. THE general subject of American secondary school programmes has been of late years a most prolific one. What with the relative or particular importance of the mother-tongue, classical studies, history, modern languages, and, more recently, manual training, the educational essayist has been rather embarrassed by the multitude of the topics presented him. As the result of much discussion, contention, and wordy warfare, we have, however, to- day, certain secondary school programmes, generally speaking quite similar in their character, marking in a more or less defined manner the routes along which our boys are traveling on their respective journeys to college, to scientific school, or to practical business life. While there is to be noted a decided advance and improvement in pedagogical methods in our secondary schools within the last few decades, it yet remains true that no intelligent reader of the programmes, as exhibited in the catalogues of our leading endowed fitting schools, and public grammar and high schools, can fail to be struck by a certain lack of co-ordination, system, and, in most instances, by an apparent want of a genuine appreciation of the real demands that the present age makes upon modern secondary schools. Once outside the old fixed lim- its of the classics, there is to be observed much disagreement among the schools themselves, both as to the proper subjects to be included in the programme and the relative time to be devoted to the studies that are placed in the school curriculum. When comparison of these programmes with those of other countries is made, we have at once afforded us a most striking exemplification of how far we still are in this country from any well-defined con- sensus as to what the modern secondary school programme really should be. In view of the revolutionary period through which the schools have been passing during the past thirty years, this is perhaps hardly to be wondered at. The broadening of the college requirements for entrance, largely brought about by the demands of a public sentiment, no longer fully satisfied with purely medi- aeval curricula, has in itself served to call for many modifications of the secondary schools' programme. With Harvard and Johns Hopkins opening their doors to students unequipped with the tra- ditional Greek, there has of course arisen a demand for prepara- tion in other prerequisites which have necessarily been substi- tuted for- Greek. In response to the general outcry for them, the courses in modern languages, in the mother-tongue, history, and SECONDARY SCHOOL PROGRAMMES. 49 particularly in science studies, have had to be greatly extended or recast. The many admirable scientific schools and colleges throughout the country have made demands for special prepara- tion that have had to be met. Furthermore, it has come to pass that the college prerequisites in the old classical studies even have been very considerably increased. Altogether it may be stated that the demands made upon the preparatory schools to-day are probably at least twenty-five or thirty per cent in excess of the demands of twenty-five or thirty years ago. Coincident with this multiplication and extension of preparatory studies, there has arisen in our country a sentiment which to no inconsiderable ex- tent has reduced the hours devoted to study. A few decades since a boy fitting for college with its limited requirements in Latin, Greek, and mathematics, spent six hours per diem in school, and, as a matter of course, expected to give two, three, or possibly more hours to study at home. Now, he spends four or five hours in the school-room ; and the sight of a text-book under his arm as he idly saunters homeward excites comment in the community as to the severe mental strain to which school-children are nowa- days subjected by rigorous masters. The result of all this is a state of affairs to which President Eliot, of Harvard University, has recently invoked the serious attention of the American public* He states that the average age of admission to Harvard University has been gradually rising for many years, and has now reached the extravagant age of eighteen years and ten months. He also notes that in view of the increased time required for the completion of his professional education, after leaving college, it follows that a man, thoroughly preparing himself for life, finds himself unprepared for self-support much before he is twenty-seven years old. This result is by no means peculiar to Harvard or to Harvard graduates, but holds true as to all colleges in the United States. Its remedy, in the opinion of President Eliot, is in both shortening and enriching our second- ary school courses of study. As illustrating what other countries have succeeded in doing in this direction, he cites the school courses of France. The hours of recitation of these courses, less elaborate and difficult than those of Germany, are, he claims, so far as hours of recitation are concerned, substantially the same as those of this country ; yet, under them, the French boy is better prepared for matriculation at seventeen years of age than ours are at nineteen. He therefore calls for a serious examination of the programmes of Venseignement secondaire class ique of France in comparison with the programmes of American preparatory * A paper read before the Department of Superintendence of the National Educational Association at Washington, February 16, 1888, published in the Atlantic Monthly, August, 1888.

I., March, 1889. vol. xxxvn. — 4 5 o THE POPULAR SCIENCE MONTHLY, schools, as likely to yield results which, can not but be conducive to educational progress in this country. As might be expected from the eminence of its author, the paper of President Eliot has excited much interest in regard to the French secondary school programmes. Much comment has resulted both as to the facts and the conclusions arrived at. The facts represented in the address as to the age of matriculates in American colleges are only too patent. The defects of the pro- grammes of the preparatory schools of this country are unfortu- nately equally patent. The great need of some readjustment of existing methods of our fitting schools and schools of grammar and even primary grades, for the benefit of boys preparing for modern collegiate, scientific, and university training, is so impera- tive that no friend of educational advance in this country can fail to welcome this valuable contribution to the literature of the sub- ject given by the President of Harvard University. But, not- withstanding his admirable paper, and the comment which has followed, so far as one can judge from the literature of the con- troversy, no one has apparently made haste to follow President Eliot's advice and make any serious comparative examination of the French and American school programmes. On the contrary, there are indications that, with true American inconsequence, many persons are already either clamoring for the adoption of the French curricula forthwith, as a panacea for all our secondary school deficiencies, or, with great lack of knowledge and accurate information, are condemning them outright as a foreign growth quite unsuited to American soil. This is to be regretted ; for as- suredly the comparative study of the programmes of the two coun- tries would give American school boards and American parents much information that should be known and accurately known. This examination is additionally desirable from the fact that, in his felicitous presentation of some characteristics of the lyce'e cur- riculum, Dr. Eliot seems to have omitted to note some of the more important features of the programmes that give them their strength, and has quite failed to point out how it happens that the French boy is really enabled to pass his examinations for the baccdlaureat es lettres at the early age of seventeen years. It may also be said that the examination is likewise desirable for the rea- son that President Eliot has inadvertentlv made some statements as to the French courses of study that the official programmes hardly seem to warrant. In the present paper the attempt will be made to present, in a somewhat more precise manner than has been undertaken by President Eliot, certain details of the curricula of not only the classical lyce'es, but also of the secondary special schools of France. In connection with this, the attempt will also be made to SECONDARY SCHOOL PROGRAMMES. 51 exhibit, with, equal precision, some facts as to comparative courses in vogue in typical preparatory schools of the United States. Following the suggestion of Dr. Eliot, particular reference will be made to the Public Grammar and Public Latin School of the city of Boston. To obtain the requisite data the writer has first tabu- lated the hours of recitation per week entering into the enseigne- ment secondaire classique and the enseignement secondaire spe- cial of France. These tables have then been brought into com- parison with similar tables, prepared on precisely the same plan, of the courses of study in both the classical and scientific depart- ments of certain typical fitting schools in the United States. The hours of recitation having been made the unit of the tabulation, the tables thus exhibit the total number of recitations in every subject taught, each year, and for the entire course of every school subjected to this examination. From the resultant figures the percentage of each study to the whole course has been also de- rived. The data as to the French courses were collated from the latest official programmes of the schools, as prescribed by the order of January 22, 1885, for the classical lycdes,* and by the order of August 10, 1886, for the secondary special schools, f The data as to American schools were derived from information supplied by the head masters of the schools in question. The result of this tabulation has been to exhibit in full relief the curricula of both countries, and to bring into graphic view some very striking points of difference in the courses of study as carried out in the French and American schools, as well as to expose many singular differences of practice obtaining in our own schools. The large space that these tables would occupy precludes their publication in connection with this paper, but the methods of compilation are here mentioned, in order that such statements as may be made by the writer as to the details of the courses of instruction in both countries may be depended on as being as absolutely correct as a careful and conscientious tabulation can make them. The programmes thus compared, at once exhibit two most im- portant facts to which President Eh'ot has made no reference whatsoever, viz. : that if a boy in France is prepared for matricu- lation at seventeen years of age, instead of nineteen, as with us, it is due (1) to the fact that, between the ages of eight and seven- teen, the French boy devotes more time to study than the Ameri- can boy; and (2) to the further fact that, with his increased amount of reading, the French lad has had eliminated from his preparatory course the serious study of subjects considered by the * Plan d'Etudes des Lycees — Programmes de l'Enseignement classique.

French, school authorities non-essential to that particular course, but which with us are still firmly intrenched in every prepara- tory school programme ; in brief, that the results obtained under the French programmes, in both the classical and scientific pre- paratory schools, are due to honest hard work, persistently con- tinued for a term of years on a well-defined plan, which is char- acterized by a complete disjunction of the courses that lead to college, from those that are intended for youth for whose antici- pated career in life a knowledge of the classical languages is not deemed essential. A comparative examination of the programmes of the Boston Latin School with the French lyce'e course brings out this excess of hours in the French school very prominently. The French boy, in his ten years' sojourn in the lyce'e, spends 8,560 hours in the recitation-room, while in the corresponding course in Boston * the recitation hours are 7,790 only. With a ten-per-cent excess in recitation hours, and a corresponding increase of study, it is evident that the two courses can not be considered " as substan- tially of the same strength." However much we might " enrich " our curricula by imitating French methods, it seems quite clear that we certainly could not, by this process, hope to " shorten " them any. Turning to the relative assignment of time to the subjects taught in common by the two schools, there is to be noted also one other point where the statistics and Dr. Eliot are at variance. One searches in vain for that " preponderance " of time given to the French language in the lyce'es as compared with the instruc- tion in the English language in the Boston Latin School. In fact, the " preponderance " is, on the contrary, altogether on the side of the Boston schools, where over twenty-eight per cent of the whole course is devoted to the mother-tongue, to only 20'8 per cent in the lyce'es. This is an interesting fact, which will doubtless be surprising to most readers. It is a prevalent opinion in the United States that in our schools too little time is devoted to the study of our own language. And lest it may be urged that this " prepon- derance " is offset by the nine hours' course per week in philosophy, given in the last year, where, President Eliot states, " French re- sumes almost exclusive possession of the programme," it may be said that, according to the official programme, this claim can not be legitimately made. The course of philosophy in question em- * The programme of the Boston Latin School, embracing six years of study, and that of the French lycees ten years, there have been prefixed to the tables of the Latin School — for purposes of comparison — the recitation hours of four years of the grammar-school courses preliminary to it. All references to the Latin School courses in this paper will, therefore, be understood as embracing the result of tabulation of ten years' school work — not that of the six years' course of the Latin School proper. SECONDARY SCHOOL PROGRAMMES. 53 braces the elements of psychology, logic, morals, and metaphysics, with a study of the principal schools of philosophy and the vari- ous philosophical authors. In connection with the last-mentioned branch of the course, as is natural, considerable prominence is given to the French philosophical writers, and one hour per week of the nine is expressly devoted to the Latin and Greek authors. This course of philosophy, admirable as it is, and interesting as (perhaps) it may be to the average youngster of seventeen years, can in no sense be properly classed as an adjunct to the mother- tongue instruction, except in so far as history, geography, or any other branch of study, carried on in the vernacular, can be so con- sidered. In the programme it is very properly classified by itself. Referring to the courses in modern languages, there is certainly here no question as to where the preponderance lies. In the French lycde the living languages are made prominent from the prepara- tory year, and the strength of the course developed in the first three years. The total is 1,000 hours, or 117 per cent of the whole hours, compared with 380 hours, or 4*9 per cent only in the Bos- ton Latin School. Latin and Greek, which naturally form the pieces de resistance of the French classical course, are, as one might expect, much more prominent than with us. The Latin is begun in cinquieme, the pupil eleven' years of age, with ten hours of recitation per week, and is continued with reduced hours for six years, giving a total of 1,500 hours, against 1,293 hours at the Boston Latin School. In the last year (classe de philosophie) the technical study of Latin is omitted, but, as above stated, one hour per week of the nine allotted to philosophy is devoted to Greek and Latin authors, the original texts being freely employed. Greek is begun in the second term of the fourth year of the course, the pupil twelve 'years of age, with two hours per week for the rest of the year, and is continued through the classe de rlietorique. Taken together, the Greek and Latin recitations of the French course occupy 2,340 hours, contrasted with 1,805 hours in the Bos- ton Latin School. The importance attached to drawing in the French scheme of instruction is shown by the considerable time devoted to it. This is in most striking contrast to the almost general neglect of this important branch of education, not only at the Latin School of Boston, but at nearly all classical fitting schools in the United States. In the French lyce'e 7'9 per cent of the whole course is devoted to drawing ; in the Boston Latin School the percentage is 2'9.* Among the various illustrations of the difference of the two * In the Latin School proper no instruction in drawing is given. The percentage referred to is derived from the preceding grammar-school courses. S4 THE POPULAR SCIENCE MONTHLY. programmes, none is more interesting than that of the rela- tive number of hours devoted to mathematics in the French and American courses. The figures are as follows : French lycee, 740 hours ; Boston Latin School, 1,387 hours. The French boy- arrives at the end of his classical preparatory course of study, having been subjected on an average to less than two hours of recitation per week in mathematical subjects. The average Amer- ican pedagogue would certainly rise with protests deep, and dis- gust profound, if ever it were proposed to him to fit a boy for college with an allowance of only 8'7 per cent of the whole school course for his arithmetic, algebra, and geometry.* Yet this is precisely what the French do — in their classical course. In the Boston representative course the percentage is 17*8 per cent. As the treatment of mathematics in the French classical course, with the limited time allotted to this study, is of general interest, a resume of it is given here. In the preparatory class of the lyce'e, as well as in the classe de liuitieme following, the allotted time is devoted to simple arithmetical work in whole numbers, mental work, and to the solving of easy problems. In septieme (third year of the course) are added decimal numbers and the metric system, with drawing of geometrical figures. In the next year there is a review of work oh whole numbers, a continuation of mental exercises and problems, and decimals ; work on fractions is entered upon, and elementary geometry is begun. In the suc- ceeding year arithmetic is continued, with the study of the rule of three, interest, discount, with simple problems in alligation, a detailed review of the metric system, and with further very ele- mentary geometrical exercises. In quatrieme, theoretical geom- etry is begun, with one recitation per week. In troisieme, the two hours per week are devoted to a review of ' arithmetical subjects, * The percentage of hours devoted to recitations in mathematics, in such typical fitting schools of the United States as have supplied data to the writer, is as follows : Boston Latin School (with four years' grammar-school course added), 17*8 per cent.

Doubtless these percentages may, in some of the schools cited, be increased or decreased in the case of certain pupils ; but they represent the mathematical courses as prescribed for the major portion of them. How strikingly the figures illustrate the different methods of treatment of the mathematical question, in the United States and France, will be understood when it is further stated that the percentage allowed to math- ematics in the French lycee course is only 8*7 per cent, and in the secondary special course, where mathematical studies are considered by the French to be especially prominent, only 17 per cent. SECONDARY SCHOOL PROGRAMMES. 55 elementary algebra is begun, and geometry is continued. In classe de rhetorique (ninth year of the course), two hours a week are devoted to recitations in solid geometry and cosmography; and in the last year (classe de philosophic), four hours per week, are devoted to a complete review of the work of the previous years in arithmetic, algebra, and geometry. It must be admitted that in this country the mathematical in- struction, sketched above, would be thought to afford a somewhat meager outfit for a young man intending to present himself for examination at any of our American colleges,. with their present mathematical prerequisites. It is also obvious that the French, who, according to President Eliot, " are quite as skillful with num- bers as the Americans," do not gain a skill in " ciphering " in the classical lyce'e course. This proficiency is obtained elsewhere, as will be further shown. The French are, indeed, not only skillful with numbers, but are as a nation eminent for their mathematical ability ; and their management of the much-vexed problem of the relative time to be devoted to elementary mathematical branches in the classical fitting schools commends itself to the serious con- sideration of American educators. A comparative exhibit of the classical lyce'e and Boston School courses clearly shows that it is to the excess of hours of recitation as a whole, and in no small degree to the holding of mathematical studies in abeyance, that the French are enabled to accomplish what they do in the way of bringing their boys to college at an early age. Give to the Boston course, for instance, ten-per-cent increase of recitations, plus the difference existing at present between the respective hours given to mathematical studies in the lyce'e and Latin School courses, and we have 1,426 hours. This is more time than is at present devoted to Latin, in the Boston Latin School, during its entire six years' course. It still more closely represents the difference in the re- spective hours given in the two countries to modern languages and drawing, with the hours of the entire course in philosophy added. It clearly follows — reversing the point of view — that Harvard has but to slightly reduce its requirements in mathematics to the French lyce'e standard, to enable it to obtain from its matriculates — those coming at least from the Boston Latin School — not only the attainments in philosophy considered so desirable by its presi- dent, but also considerable proficiency in such other branches of the French programme as its honorable faculty may " elect " to receive. With the present public sentiment, and especially in view of the present requirements in mathematics on the part of American colleges, it is not probable that we can look for a reduction in mathematical studies in our classical preparatory courses to the point exhibited by the programmes as existing in France. But 5 6 THE POPULAR SCIENCE MONTHLY. that tlie protest against the excessive and unnecessary time given to mathematical instruction in all our schools which has begun, will continue, none can doubt. As is well known, no primary or secondary school programme of this country can be scratched without revealing an omnipresent Tartar known as arithmetic. This mathematical Cossack is ever found firmly settled in his saddle, and foraging for subsistence hither and yon, upon friend and foe alike. The result is, that in the classical preparatory school the boy is hampered and handicapped by serious mathematical studies which absorb time that he could more profitably devote to his mother-tongue, to modern languages, and to science studies. On the other hand, in the scientific or English courses, the pupil fitting for the scientific school, or for business, is forced to take unwelcome draughts of Latin. These last are somewhat diluted, it is true, and are given perhaps on the general principle entering into the administration of certain family medicines, viz., that if not of any direct service to the patient, they can do him no pos- sible harm. But in point of fact, while as a rule the Latin given in these brief courses can be of little or no value to a pupil fitting for the scientific school, time is taken from subjects having a direct personal bearing on his future career. It is interesting to note how, in France, this feature of instruction is managed. A French boy having passed through the grades of the lyce'e classique, as exhibited in the preceding table, and intending to devote himself to a literary profession, proceeds without further ado to his examination for the baccalaureat es leitres wherein mathematics plays but a subordinate part, as is indicated by the small percentage of time given it in the lyce'e course. But, for the benefit of graduates designed for the national schools, or for those who prefer to present themselves for examination for the baccalaureat es science instead of es lettres post-graduate lyce'e mathematical courses are instituted. The classe de rnathema- tiques elemehtaires , for instance, has for its object the study of matters comprised in the programmes of the baccalaureat es sci- ences, as well as those of the military (Saint-Cyr), the naval, and forestry schools and the central school. The curriculum of this class devotes seven and a half hours per week to mathematics, four and a half hours to science studies, two each to the mother- tongue, Latin and modern languages, three hours to history and geography, one hour to philosophy, and four hours to drawing. This course is of but one year. It is usually taken by pupils from the classe de rhetorique, but may be taken by pupils from the classe de philosophic who wish to review and increase their mathe- matical attainments. A much stiffer and more comprehensive drill in mathematics is afforded by the classe de mathematiques speciales. This course is also of but one year. The instruction SECONDARY SCHOOL PROGRAMMES. 57 given in this class has for its object the preparation of pnpils who have completed the lyce'e course, and who purpose entering the polytechnic, the superior, or the central schools. None are ad- mitted to this course who have not previously manifested an apti- tude for it. The hours of recitation per week are, mathematics eleven hours, descriptive geometry three hours, physics and chemistry five hours, natural history three hours, French lan- guage two hours, modern languages two hours, history and geog- raphy three hours, and drawing two hours ; total, thirty -one hours. The instruction to-day given in France under the name of Ven- seignement secondaire special has found a secure footing only after many years of violent discussion and constant opposition. Its career, however, has been steadily advancing and gaining in public consideration ever since its organization in 1865. Its pro- gramme was extended and revised in 1881, and in 1886 it was organized on its present basis. The courses of study have been framed with especial reference to the requirements of a large class of pupils of good social position, who have neither the desire, the tastes, nor perhaps the leisure for long years' study of dead lan- guages. It is a response to the needs of a large class for a prepa- ration for actual life in various careers, which the classical courses are incapable of giving. The school is in a sense the Realschule of the French, differing from its German congener, however, by the entire elimination of Latin from its programme. The course comprises six years of study, crowned, at its success- ful termination, by the diploma of bachelier de Venseignement secondaire special, the possession of which entitles the holder to admission to the examinations for the baccalaureat es sciences, for the military school of Saint-Cyr, and, with the exception of the Polytechnic School, which still holds to its classical requirements, to other national schools with requirements of a general similar character. However interesting, as an illustration of French school meth- ods, the curriculum of the secondary special schools may be, the severity of the course, as a whole, renders it unlikely that it will ever be very closely imitated in this country. The recitations here range from twenty-five to twenty -nine hours per week, giv- ing, for the whole course, 6,360 hours, against 4,360J hours in the American representative of the same type of school.* The official * As the secondary special schools of France occupy about the same place in the French system as the upper classes of grammar schools and the English high schools occupy in ours, the French programmes of these schools have been brought by the writer into comparison with a typical American school — the courses of the two upper classes of the grammar schools and those of the English High School of Boston being employed as a fair American representative. 5 8 THE POPULAR SCIENCE MONTHLY. programme shows that the instruction of these 6,360 recitation hours are distributed as follows : Mother-tongue, 1,000 ; modern languages, 1,160; history, 360; geography, 280; mathematics, 1,080 ; science studies, 960 ; drawing, 960 ; penmanship, 160 ; book- keeping, 80 ; morals, 40 ; legislation, 80 ; political economy, 40 ; philosophy, 160. The ages of the pupils average eleven years in the first and sixteen in the last class. The recitation hours of a pupil passing through the last two grades of the grammar school, and the four years' course of the English High School in Boston are, barring certain changes on account of options, as fol- low : Mother-tongue, l,illi ; modern languages, 494 ; history, 570 ; geography, 152 ; mathematics, 722 ; drawing, 760 ; book-keep- ing, 95. Here, again, as in the case of the French classical lyce*e course, the instruction in the mother-tongue is found to be less than in the American representative school. The hours devoted to mod- ern languages (1,160) are, in fact, somewhat in excess of those given to French (1,000), and, it may be added, are in most marked contrast to the time allotted to the same study in the Boston High-School programme (494), even after the latter has received a credit under this head for a certain number of hours that in point of fact are used by many pupils for Latin. Mathematics, which, as has been seen, plays but a subsidiary role in the classical lycee course, in the secondary special course assumes more prominence comparatively, the average being 4£ hours against 3-J- hours' recitation per week in the typical Ameri- can programme. Yet even here it is not up to what may be termed the United States standard. A tabulated exhibit of the hours of the classical courses of the two countries shows that an average of only one hour and fifty minutes per week is given to mathematics in the classical lyce'e course, compared with an aver- age of three hours and forty minutes in the Boston classical school course. A comparison of that course with the French secondary special programme develops also the fact that a typical American classical school not only devotes more hours to mathematics than the French consider essential for a preparatory scientific course, but also exhibits the further surprising fact that the Boston Eng- lish High-School course, with two years of grammar-grade school prefixed to it, actually gives less time to mathematics than is de- voted to that study in the six years' course proper of the Latin School. And this is not by any means peculiar to the Boston school courses. The programmes of other schools exhibit a treat- ment of the mathematical subjects quite similar. At Phillips Exeter precisely the same number of hours is given to mathemat- ics in the classical and scientific courses. At Williston, even after adding the course in surveying to the mathematics, the per- SECONDARY SCHOOL PROGRAMMES. 59 centage of the latter to the whole course is less than on the clas- sical side. From the data here given it seems clear that if we are to hope to pnt our schools on anything like an equality with those of France, to say nothing of those of other civilized countries of the world, certain modifications of our school programmes have cer- tainly to be made. First and foremost among those changes there would seem to be indicated a need for a certain specialization of our school courses with reference to the different demands made upon the schools by different classes of pupils. That our schools of primary and secondary grade, as they stand to-day, do not re- spond to the varied requirements of American society, seems quite obvious. The complaint of President Eliot sufficiently indicates their shortcomings, so far as a preparation for college is con- cerned. For many years professors and teachers at scientific and technical schools have mourned the dearth of preparatory schools that should give them pupils not handicapped by great deficien- cies in training of the powers of observation. Business men are quite unanimous in their belief that the schools do not afford a satisfactory training for commercial pursuits, while he who runs may read their many deficiencies for the constantly increas- ing class of pupils whose period of school life terminates in the grammar grade. The main cause of the present stage of development of the school system is not so deeply hidden that one has to search long for it. The average American school programme at the present time is simply a living illustration of a development, on Amer- ican lines — influenced and modified by national characteristics — of the old educational theory that literature and language are the basis of all mental culture and training. The educational structure reared on this theory, beset and more or less dam- aged by modern assaults, has been repaired here and patched there, but the old framework and the old foundations have ever remained to cramp intelligent reconstruction and practical re- form. The result is in the main a hotchpotch with which no one is thoroughly satisfied. It would seem to be a clear case of the old house repaired and refurnished, until it is satisfactory to no one. It is passing strange that the school system of the United States, in respect to its want of specialization, should stand almost unique among the many examples of the national aptitude in adopting means to ends. In business life, in professional life, in industrial pursuits, our nation has shown itself peculiarly clever in its concentration of labor in systematic, well-defined channels having special reference to the results to be attained. Yet, when we come to compare our school programmes with those of other nations, we not only find that we do not do as much school work, 60 THE POPULAR SCIENCE MONTHLY. nor as satisfactory work, but that what we do is done in an anti- quated and unscientific manner. • In France, for example^ we find a school system that in its superior primary course gives to the child of the humblest artisan not only a solid foundation in all essentials of mother-tongue instruction, but, by means of its complementary courses, in manual training and modern lan- guages as well. We likewise find a clean-cut, well-defined course in the special secondary schools for the child who seeks prep- aration for commercial or professional life by modern meth- ods ; while, by the systematic arrangement of its classical lycee course, results are achieved which excite the admiration and envy of the president of one of our most honored universities. Turn- ing to our own programmes, we find what can only be character- ized as a more or less futile effort to build on one foundation several distinct structures, each one of which is diverse in the special ends sought to be accomplished. In our effort to do everything, we have failed to do anything sufficiently well to entitle it to favorable comparison with the results attained by a more skillful apportionment of labor. We can also learn from the French programmes that if Amer- ican schools are to accomplish results comparable with those attained in France, American children have not only to work on more specialized lines, but have also to work more. There can be no doubt that the outcry against "long school hours" and " home study," which for many years past has been so resonant in this country, has seriously affected the efficiency of our schools. As the exhibit of school programmes here given shows, the average hours of recitation in American fitting schools are very consid- erably less than in those of France. And those of France are to about an equal degree less than the hours of' the German gymna- sia and Realschulen. It is full time that a halt be called on the further progress of this absurd clamor. The idea that a healthy American boy, between the age of eight and fifteen years, let out of school, as he generally is in these days, at from one to two o'clock, should not do a certain amount of systematic study at home, certainly can but be characterized as absurd. It is probable that but few persons, who have not made special inquiry in regard to it, appreciate the extent to which this sentiment against out-of- school study now prevails in this country. If it has had the effect of crippling the public schools, it may be said that it has really par- alyzed many private ones where this feeling is pandered to. The advanced age of pupils entering the private fitting schools, as well as the advanced age of college matriculates, is to a great extent due to this disinclination of parents to submit their chil- dren to regular systematic study in their earlier school life. In collecting the data for this paper the writer has been pleased to SECONDARY SCHOOL PROGRAMMES. 61 ascertain that on the part of certain endowed home fitting schools established on recent foundations, direct efforts are being made to counteract these deficiencies of earlier years by a systematic reg- ulation of pupils' time — both as regards study and recreation. The result, as could be anticipated, is a marked broadening of the school course, as well as a decided decrease in the ages of the senior class pupils. It is because of the possibilities in this direc- tion, as well as to respond to the rapidly increasing demand in the United States for them, that thoroughly good preparatory home schools, which shall fit boys for college and scientific school in a rational manner, are now especially in request. The average home school that fits for everything or anything, and that is a fraud from its glossy catalogue to its ornate diploma, is suffi- ciently well known to the average parent, and is not here alluded to. The home schools now needed to meet our modern requirements can have an existence only by virtue of some man or men willing to liberally endow them. It would seem, too, that the ideal pre- paratory home school should embrace at least six years of instruc- tion. It should be fully equipped and prepared in all respects to respond thoroughly to the three distinct demands that are now made upon the modern fitting school, viz. : (1) preparation for college with all the maximum requirements in the classics ; (2) preparation for college without Greek, but with adequate modern language and science-study substitutions ; (3) preparation for the scientific school without Latin or Greek, but with equivalent and honest substitutions of somewhat increased mathematical instruc- tion (as compared with the classical branches), together with modern languages and science studies, so taught that in all re- spects of severity of course they shall equal in disciplinary results the drill given in the classical courses. To the response that may be made, to the effect that we already have preparatory schools doing precisely this work, and doing it well, it is claimed that the few facts presented in connection with this paper are in themselves a sufficient refutation. There is another point. The writer would be among the last to impugn the ability, the conscientious devotion, the peculiar fitness, even, of the heads, and, generally speaking, of the staffs of these classical schools, for he has the highest appreciation of them. But the fact remains that, with hardly an exception, the faculties of the old clas- sical preparatory schools that have been erected on the old endow- ments seem to be incapable of giving absolutely fair and honest treatment to their so-called preparatory scientific or English ad- juncts. They are bound hand and foot in the old traditional bonds. By reason of their educational bias they are precluded from yielding a hearty, enthusiastic response to any demand that a classical curriculum does not meet. In point of fact, why should 62 THE POPULAR SCIENCE MONTHLY. they ? They have personally no faith whatever in the real value of any training except that gained by the study of the classics. They appreciate that the scientific course is but a graft on the old trunk, made in great measure for the pecuniary advantage of their establishment, and in response to a popular demand, which they hope and pray may soon find a speedy death. They have no hesitation in proselytizing in the ranks of the brighter " scien- tific" pupils sent them, for the benefit and glory of the "full rounded course " — in embryo. Here again they are justified, for the preparatory scientific courses are in fact but indifferent patch- work compromises between the claims of the past and the de- mands of the present. These courses really do give no thorough secondary school work in any one subject, except possibly mathe- matics. With an apparently semi-superstitious feeling as to the mysterious results produced on the human mind by communion with a Latin grammar, for even a limited period, little dabs of Latin have been introduced into these courses. This study ex- tends in the scientific course of some preparatory schools through one year, sometimes two, rarely three years. With no desire what- ever to depreciate the undoubted value, to certain pupils, of an honest, bona fide study of the classical languages, continued for years, it is submitted that these cursory courses of Latin can give no results in any way commensurate with the time expended on them. In Germany the classicists have ever stoutly maintained that any reduction of hours devoted to Latin in the gymnasium course would deprive it of all value ; yet they there give to it nine hours per week for five years, and eight hours for four years more. In the Realschulen they devote to it eight hours a week for two years, six hours for three, and five hours for four years. The value that the German school authorities would place upon a course of Latin of three or four hours per week for one, two, or even three years, affords a pretty little arithmetical problem whose solution is respectfully relegated to the designers of these American courses. Beyond this Latin and the regulation four or five hours a week in mathematics, what else does one find in our preparatory " scientific " courses ? As but few of the more modern scientific schools or schools of technology have requirements in Latin— and as one and all of them are desirous of obtaining from their matriculates all, and more than they often get, in the way of modern languages— one could properly expect that the fitting schools would afford opportunities for solid preparation in French and German. As will be seen, this demand is by no means well responded to. In the scientific courses of one prominent fitting school consulted by the writer, no instruction whatever in mod- ern languages is given. In the programme of another of these schools—which is also the most modern, therefore lending some SECONDARY SCHOOL PROGRAMMES. 63 encouragement to the hope of more enlightened procedure as time rolls on — we find that modern languages enter into but three of the four years' course. Leaving the modern languages, and look- ing at the time devoted to science studies, the same desultory treatment is found. There is encouragement to be had in the assurances of laboratories erected and in course of erection, and in the information that in some fitting schools Harvard's require- ments in experimental physics and chemistry can be fully met ; but, so far as the curriculum itself of the scientific course is con- cerned, we have but the hope of something better in the future. If one glances at the time allotted to the education of the hand by means of drawing, or if one is curious in the matter of history and mother-tongue instruction, almost equally unsatisfactory work is encountered. Yery properly, any intelligent parent, studying such courses with a view of submitting to one of them a boy whom he has decided to educate on modern methods, hesi- tates. It is not strange that in his extremity he finally concludes that a serious, well-defined course in the ancient languages is of more value than the olla podrida preparation presented him on the " scientific " side. As this is precisely what the makers of the programmes themselves believe, this conclusion is applauded — and there is rejoicing over the rescue of another boy from a " one- sided education " ! A comparative examination of French and American prepara- tory school programmes, therefore, at least yields this much ; that our educational methods are in great need of thorough revision if we are to hope to stand well alongside the French in all that per- tains to judicious preparation for college, for scientific school, or for the general demands of modern life. This examination further shows that we stand in pressing need not only of fitting schools that meet these demands as they exist to-day, but so untrammeled and free from all sort of sectarian or educational bias that they can freely expand and respond to the demands that will assuredly follow as years roll by, and colleges and universities still further yield to the influences that are slowly but surely liberating them from the traditions of the past. An honest home fitting school, firmly founded on the principle of responding to the demands as they exist to-day — not as they existed a century or two ago — suffi- ciently endowed to render it free to maintain firmly all the re- quirements of its different rational courses of instruction, seems to be the great educational need of the day. As the weakest link of dur educational chain lies most undoubtedly in the earlier years of the preparatory course, this school should be prepared to take pupils at twelve years of age ; it would be better if they could be taken at ten, and the course be made to embrace eight years in- stead of six. It should be a home school, for the reason that, with 6 4 THE POPULAR SCIENCE MONTHLY. the prevailing habits of American family life, it is becoming with us every day more and more impossible to obtain from pupils the proper amount of work, associated with the proper regime as to exercise and recreation— and diet even— so long as they remain under the parental roof. Such a school could not fail to soon stand as an exponent of the development of a higher, better, and truer secondary education. It would be a model for the encour- agement of other schools of a similar character that would soon come into existence, and it would make its impress upon the pro- grammes of public secondary schools. Any man of wealth who is animated by the ambition of sending his name down to a grateful posterity linked with a noble educational benefaction, could not to-day find a more deserving field for the investment of a spare million than in the founding of such a school. To the colleges, to the universities, to the schools of industrial science, would the money thus invested be of as great benefit as if donated directly to them. For, as the gentle rain sinking far down into the earth among the rootlets refreshes and revives the mature tree, so would a preparatory school of this character give to the higher institu- tions of learning strength at a vital point where it is peculiarly needed. -♦•♦«•- SCENES ON THE PLANET MERCURY.* Br G. V. SCHIAPAEELLI, OF THE OBSEBVATOBY OF MILAN, ITALY. "VTO one of the planets that were known in ancient times is so -i-N difficult to observe as Mercury, and none presents so many obstacles to the study of its orbit and physical constitution. As to its orbit, Mercury is the only planet the course of which seems even now to have partly cut loose from the laws of universal gravitation, and the theory of which, although well built up by the genius of Leverrier, is still in considerable disagreement with the observations. The little we know of its physical construc- tion is derived from the observations made a hundred years ago by Schroeter at Lilienthal. A telescopic examination of this planet is really a difficult affair. Describing a small orbit around the sun, Mercury is never seen so far from it as to make it possible to observe it, in temperate latitudes, in the full darkness of night. It is rarely possible to observe it in the twilight before sunrise or after sunset ; it being then so near the horizon and so affected by the agitations and unequal refractions of the lower strata of the atmosphere that it usually presents itself to the telescope with * Address before the Royal Academy Dei Lincei, December 8, 1889. SCENES ON THE PLANET MERCURY. 65 an uncertain and flaring aspect which appears to the naked eye as a strong scintillation. For this reason the ancients called it SrtX/W, or the scintillating star. No other resource is left than to essay observations in broad daylight, in the presence of the sun always near, and in an always illuminated atmosphere. Some efforts I made in 1881 persuaded me that it was possible both to see the spots of Mercury and to get sufficiently connected and continuous observations of them in broad daylight, and I de- cided in the beginning of 1882 to make a regular study of this planet. During the eight years since then, I have had Mercury in the field of my telescope several hundred times ; often, it is true, with little profit and at the expense of great loss of time, either be- cause of the agitation of the atmosphere, which is often strong during the day — especially in the summer months — or on account of the insufficient transparency of the air. But by patience I have succeeded in seeing the spots on the planet one hundred and fifty times with more or less precision, and in making also fairly satis- factory drawings of them, employing at first, for the purpose, our eight-inch Merz equatorial, but afterward our great eighteen-inch Munich instrument. I found the rotation of the planet quite different from what it has hitherto been supposed to be, on the basis of insufficient obser- vations made with imperfect telescopes a hundred years ago. I may describe it in a few words by saying that Mercury revolves around the sun in the same manner as the moon revolves around the earth. As the moon's journey around the earth is performed in such a way that it always shows nearly the same face and the same spots, so Mercury, in traversing its orbit around the sun, constantly presents nearly the same hemisphere to that source of light. I say nearly — not exactly — the same hemisphere. For Mercury is subject, like the moon, to the phenomenon of libration. In observing the full moon, even with a small telescope, we re- mark that the same spots generally occupy the central regions of its disk ; but, if we study them and their distances from the east- ern and western borders more minutely, we shall soon perceive, as Galileo first did about two hundred years ago, that they oscil- late to a considerable degree, now toward the right and now toward the left — exemplifying the phenomenon called libraiion in longitude. . This arises from the moon's directing one of its diam- eters perpetually and almost exactly, not toward the center of the earth, and not toward the center of the elliptical lunar orbit, but toward the one of the two foci of its orbit which the earth does not occupy. To the observer occupying this point, the moon would consequently always present the same appearance. But to us, who are at a mean distance of forty-two thousand kilometres from that point, the moon presents somewhat different aspects VOL. XXXVII. — 5 66 THE POPULAR SCIENCE MONTHLY. according to the time when we look at it, sometimes showing us a little more of its eastern, sometimes a little more of its western, regions. Mercury presents itself to the sun in different phases of its cycle in a similar manner. It constantly directs one of its diameters, not toward the focus of its elliptical orbit which is occupied by the sun, but toward the second focus. These two foci being distant from one another not less than a fifth of the whole diameter of the orbit of Mercury, the libration of the planet is enormous. The point that receives the rays of the sun verti- cally changes its place on the surface of the planet, and performs an oscillatory movement along the equator forty-seven degrees in amplitude, or through more than one eighth of the equatorial circumference. The whole duration of this oscillation, including the going and returning, is equal to the time employed by Mer- cury in traversing its orbit, or about eighty-eight terrestrial days. Thus Mercury stands oriented toward the sun like a magnet toward a mass of iron ; but this orientation is not constant to the point of excluding a movement of oscillation of the planet to the east and to the west, like that which the moon performs toward us. This oscillation is of great importance for the physical con- dition of the planet. Suppose, for instance, that it did not exist, and that Mercury always turned the same hemisphere to the light and heat of the sun, the other hemisphere remaining plunged in perpetual night. The point of the surface situated at the central pole of the illuminated hemisphere would have the sun eternally in the zenith ; the other points of the planet accessible to the solar rays would have the sun always at the same point in their horizon, at the same height, without any apparent movement, without any perceptible change ; consequently, no alternation of night and day, no variety of season ; the stars eternally invisible because of the perpetual presence of the sun ; and, Mercury hav- ing no moon, we can hardly imagine how the inhabitants of those regions, condemned to an endless day, could find a means of regu- larly computing time. Such are, in fact, nearly the conditions that prevail in Mercury, but only approximately. The oscillating movement of the Mer- curial globe as toward the sun would be attributed by an observer on the surface of the planet to the sun, as we attribute to the sun the diurnal movement which really appertains to the earth. To us the sun seems to circle regularly from east to west, defining in twenty-four hours the period of day and night ; to the observer on Mercury, the sun will describe a back-and-forth movement through an arc of forty-seven degrees in the celestial vault, while the position of the arc as toward the horizon will always be the same. The complete period of the double oscillation will com- SCENES ON THE PLANET MERCURY. 67 prise almost exactly eighty-four terrestrial days. According as the arc of solar oscillation is all above the horizon of the observer or all below it, or partly above and partly below it, there will be different appearances and a different distribution of light and heat. In the regions, covering three eighths of the planet, where the arc is all below the horizon, the sun will never be seen, and the darkness will be perpetual. Thick and eternal night will reign there, except perhaps from the accidental appearance of some light produced by refraction and atmospheric glows, or phe- nomena like the aurora borealis ; together with the light emitted by the stars and planets. Another part of Mercury, including also three eighths of its surface, will have the arc of oscillation all above its horizon, and will be continually exposed to the rays of the sun, without any other change than the variations in the obliquity of the rays through the different phases assumed during the period of eighty- eight days. Night is absolutely impossible. In other regions, cov- ering a quarter of the planet, in which the arc of oscillation is partly above and partly below the horizon, there will be alterna- tions of light and darkness. In these privileged regions the pe- riod of eighty-eight days will be divided into two intervals, one characterized by a continuous light, the other by darkness ; the two intervals will be equal in some places, of different length in others, according to the position of the place on the surface of the planet, and the length of the part of the solar arc which appears above the horizon. The possibility of organic life in a planet constituted after this manner depends on the existence of an atmosphere capable of dis- tributing heat into different regions, in such a way as to diminish the extremes of heat and cold. Schroeter, a hundred years ago, suspected the existence of an atmosphere round Mercury; my observations afford more definite indications of it, and affirm its existence with a much greater probability. The spots of the planet are most clearly visible when they are in the central parts of the disk, and grow dimmer and ultimately disappear as they approach the border. I have been able to assure myself that this phenomenon is not merely due to the greater obliquity of the per- spective, but is because some obstacle is really presented to the view of spots situated in such positions. That obstacle can hardly be anything else than the greater extent of atmosphere that the light-rays have to traverse in coming from the edges than from the center of the disk. We have, therefore, reasons for believing that the atmosphere of Mercury is less transparent than that of Mars, and more nearly like that of the earth. The circular contour of the planet, moreover, in which the spots become less visible, always appears more luminous than the rest, but often irregularly 68 THE POPULAR SCIENCE MONTHLY. luminous, more so at some points than at others ; and sometimes we can see on its borders bright white regions that remain in sight several days in succession, but are generally changeable, and show themselves sometimes in one place and sometimes in another. I attribute these phenomena to condensations going on in the at- mosphere of Mercury, which reflects more light into space the more opaque it becomes. Similar white regions are also often seen in the interior of the disk, but they are not so brilliant there as on its border. Further, the dark spots of the planet, while they are permanent as to form and arrangement, are not always equally evident. They are sometimes more intense, at other times paler. Sometimes, also, one or another of them will become mo- mentarily invisible. Such peculiarities can not be attributed to any other cause than atmospheric condensations similar to our clouds, which veil the ground of the planet in different degrees, sometimes in one region, sometimes in another. An observer, looking from the depths of space upon the countries of our earth covered with clouds, would perceive a like spectacle. Very little can be said of the nature of the surface of Mercury. We must recollect that three eighths of it are inaccessible to the solar rays and to sight ; on that side, therefore, we have but slight hopes of ever learning anything certainly. It will also be hard to gain a correct and sure knowledge of the part we can see. The dark spots, even when they are not clouded, usually appear under the form of extremely thin trails of shadow. In ordinary con- ditions they are distinguishable only at the expense of much atten- tion and weariness. Under the best conditions they have a brown, warm tint, like that of sepia ; of a tone very indistinct upon the general color of the planet, which is usually of a clear rose bor- dering on copper. Forms or bands so vague and diffuse, with indistinct borders, always leaving a place for arbitrary definition, are not easily represented in a satisfactory manner. Still, I be-< lieve the indeterminateness of outlines is, in the majority of cases, only apparent, and a result of the insufficient optical power of the instrument ; for the more perfect the view and the finer the image we get of the shadows, the more do we find them disposed to break up into a multitude of smaller details. By employing more pow- erful telescopes, they could doubtless be resolved into more re- duced forms. While it is so hard to make a good study of the dark spots of Mercury, it is not easy to express a well-founded opinion upon their nature. They might be attributed to the different materials composing the solid surface of the planet or to its structure, as we know is the case with the moon. But if we are disposed to con- sider them as in some way resembling our seas, and to suppose the existence of an atmosphere around the planet, with condensa- SCENES ON THE PLANET MERCURY. 69 tions and precipitations, I do not know of any decisive arguments that can be opposed to the opinion. The spots are not gathered in large masses, but are disposed in areas and zones of small extent ; are greatly ramified, and alternate with considerable uni- formity with clear spaces. We may, therefore, conclude that no vast oceans or great continents exist on Mercury ; but that land and sea interpenetrate one another and give rise to conditions very different from those which exist on the earth, but which may be more desirable. Mercury is a world that differs from ours as much as Mars does. The sun lights it and warms it much more intensely than it does the earth, and in a very different way. If life exists in that world, it is doubtless under conditions so different from ours that we can hardly imagine them. The eternal presence of the sun, darting its rays almost vertically on some regions, and its perpetual absence in the opposite countries, would seem intoler- able to us. And yet, if we reflect upon it, we shall remark that such a contrast would produce a more rapid, more powerful, and more regular atmospheric circulation than that which spreads the elements of life over the earth ; and it possibly is brought about in this way that as complete and even perhaps more perfect equi- librium of temperature is produced on the whole planet than with us. Mercury, by directing the same face toward the sun during its whole revolution, is peculiarly distinguished from the other plan- ets, all of which the length of whose rotation has been determined, turn round their axes in a few hours. This mode of rotation, how- ever, which would be unique among the planets, seems common enough among the satellites. All testimony is to the effect that our moon has always conformed to it. The first three satellites of Jupiter probably behave in the same way, and the observations of Auwers and Engelmann demonstrate that the fourth does so. Cassini verified the same fact for Japhet, the eighth satellite of Saturn. It may, therefore, be considered the rule among the sat- ellites, while it is an exception among the planets. The exception may probably be attributed to the proximity of Mercury to the sun, and perhaps also to the fact that it has no satellites ; and depends, I think, on the way Mercury was formed when the solar system took its present shape. The peculiarity constitutes a new datum to be added to those which astronomers will have to take account of in studying solar and planetary cos- mogony. — Translated for the Popular Science Monthly from a French version by F. Terby in del et Terre. 7 o THE POPULAR SCIENCE MONTHLY. ARTIFICIAL HONEY AND MANUFACTURED SCIENCE. Br ALLEN PRINGLE, PRESIDENT OF THE ONTARIO BEE-KEEPEBS' ASSOCIATION. TTTE are often told that this is a scientific age, and the state- VV ment is undoubtedly true. The world now more than ever before looks to science as a secular if not a spiritual guide. How- ever much their speculations may be questioned and controverted, the scientific book and the scientific man are popularly accepted as authority, at least on matters of physical and historical fact. The veracity of science therefore is, or ought to be, above suspi- cion. How careful, then, ought the teacher and exponent of sci- ence to be that his assertions are true ; that his alleged facts are facts ; and that even his speculations are free from the appearance of dogmatism ! He needs to be especially particular when writing for the general public, for people untrained in science will accept his statements as expert testimony. Errors will thus be sure to mislead his readers, many of whom are without the knowledge that would enable them to discriminate between the true and the false in his assertions. In The Popular Science Monthly for June, 1881, appeared an article on Glucose and Grape-Sugar, by Prof. H. W. Wiley. In that article the following unfortunate statement was made : " In commercial honey, which is entirely free from bee mediation, the comb is made of paraffin, and filled with pure glucose by appropriate machinery/' To say that there was not one word of truth in that extraordinary assertion is the short and proper way to put it, and that is exactly what I undertake to say. There was not a tittle of evidence that any such honey had ever been made up to that time, nor is there a particle of evidence that any such honey has since been made. Nevertheless, this vile slander on an honest and honorable in- dustry has done incalculable injury to bee-culture in America, if not throughout the world. A lie is said to travel half round the world while the truth is getting ready to start, and this one proved no exception. Though contradicted and refuted over and over again, it still lives and is still going. Newspapers still keep iterating and reiterating Prof. Wiley's slander, but they seldom publish a correction. Thousands of people, common and uncom- mon, still believe that scientific yarn that comb-honey is manu- factured throughout without " bee mediation," and why shouldn't they ? The former believe it because the newspapers say so, and the latter because the magazines and encyclopaedias say so ; for it is a fact that this itinerant fiction has actually found a place in ARTIFICIAL HONEY AND MANUFACTURED SCIENCE. 71 the American Cyclopaedia and the American supplement to the Encyclopaedia Britannica. In justice to the latter, however, it mnst be said that the British work, whose publishers repudiate the American supplement, contains nothing of this. Here is what the American Cyclopaedia says on the subject: " Glucose is very extensively fed to bees, which eat it with great avidity, and store it away unchanged as honey. It is also put up directly in trade as honey — with which bees have had nothing to do — being put by means of appropriate machinery into artificial combs made of paraffin " (page 834, vol. viii, edition of 1883). The American supplement to the Encyclopaedia Britannica has this information on the subject : " Honey is manufactured on the same plan, only here the bees are employed to assist in the fraud. They are furnished with a supply of starch-sugar, which they store in their combs, when these combs are also fraudulent, being made from paraffin and furnished to the bees, who fill them with glucose and cap them with genuine wax. It is difficult to see how the art of adulteration could be carried further" (page 41, vol. i, Hubbard Brothers, Philadelphia and New York, 1885). Argument and refutation failing to kill the falsehood, the ed- itor of Gleanings in Bee-Culture — a responsible man financially — offered a reward of one thousand dollars to any one (including Prof. Wiley) who would produce some of the so-called " manu- factured " honey, or designate the place where it was made or could be found. This offer is still open and good. The writer of this article also offered through the press a reward of one hun- dred colonies of bees (equal to about one thousand dollars) to any one who would produce some of this "artificial honey." This offer also is still open and good. None, however, has ever been produced. No one has yet come forward to claim the cash or the bees. Prof. Wiley had supplemented the assertion above quoted with the following additional information, probably to encourage the manufacturers : " This honey " (that is, the manufactured article) " for whiteness and beauty rivals the celebrated real white-clover honey of Vermont, but can be sold at an immense profit* at one half the price." Now, had that business of honey manufacture been as practicable as profitable, the temptation to embark in it would have been almost too much for human nature to resist. But it seems nobody went in, while nearly everybody believed that other bodies were in. However, Nature's dearth is likely to produce conviction where facts, arguments, and rewards failed to do so. The seasons of 1887 and 1888, especially the latter, were unpropitious for the " busy little bee," and yielded but little honey. The crop was a 7 2 THE POPULAR SCIENCE MONTHLY. general failure, not only in America but in Europe. The modi- cum of honey produced, especially of comb-honey, was soon ex- hausted, and the dealers as well as consumers, North, South, East, and West, were crying out for honey. The producers were inun- dated with letters and orders which they could not fill. Now, here was the grand opportunity for the manufacturers of "artificial honey." If the article could be sold "at an immense profit at half the price " of the genuine article, as Prof. Wiley assures us, these bogus manufacturers could have coined money — there were " mill- ions in it " apparently. But they failed to appear. The glucose was available, the paraffin ditto, and the " appropriate machinery " ought, in the interval under the law of progress, to have become still more " appropriate " and perfect in its work ; but, strange to say, the famine of honey continued. The tempting prices were offered in vain. Not a pound of the stuff ever " materialized/' so far as anybody could find out. Nor was this gap in the extracted honey, caused by the drought, filled by any artificial substitute, which also goes to prove that the prevalent notion that honey is extensively adulterated has very little foundation in fact. Con- sidering the comparatively low market prices of honey the past few years, and the facility with which the genuine article can be produced in modern scientific bee-culture, adulteration would hardly pay for the trouble. That there is but very little adulteration either of comb or extracted honey may be safely asserted. The prevalent popular belief to the contrary may be accounted for in two ways — by the prevalent ignorance of the character and what I might call the habits of honey, and by the erroneous teachings and misleading reports of the authorities under review. While it may be said, in general terms, that honey chemically consists of sugar and water, in the proportion usually of about seventy-five per cent of the former to twenty-five of the latter,* these elements vary so much in their proportions in different grades of honey gathered from so many different flowers at different seasons of the year that there is no sure test, chemical or other, of honey. Even the polari- scope, but recently considered a certain test of its purity, and still so considered by some analysts, is found to be uncertain and unreliable. While generally in pure honey the ray of light is turned to the left, some samples, equally pure, though perhaps stored rapidly and capped prematurely, may contain so much cane-sugar that the ray is turned to the right. Hence the mis- takes of chemists, relying upon the integrity of the polariscope, in passing up on the purity or impurity of honey. They have * According to C. Tomlinson, F. R. S., F. C. S., dextrose thirty-eight per cent, levulose thirty-six, water twenty-two, and the remaining four, salts, wax, pollen, gluten, and aromatic and coloring matters. ARTIFICIAL HONEY AND MANUFACTURED SCIENCE. 73 pronounced samples adulterated which were known to he the pure products of the flowers gathered by the bees. Every apia- rian specialist knows that during the course of one good honey season, beginning with the early spring bloom of willow, maple, fruit, etc., and ending with the fall bloom of golden-rod, buck- wheat, etc., he can get nearly a dozen different grades or kinds of honey — in color from the very light, almost transparent linden to the turgid and black buckwheat, and in flavor from the mild and delicious sweet to that which is strong, rank, and quite un- palatable to some tastes. Let a person with no special knowl- edge of honey be presented with the former for his sight and palate, and then with the latter, and, ten to one, he will declare that the one sample is not honey at all, but a vile imitation. Then, again, good, pure honey, through mismanagement, may be- come so deteriorated in quality and altered in taste as to at once provoke suspicion of adulteration. Granulation was also regarded as a sure test of the purity of honey, but it is not so, as some pure grades, containing only the non-cry stallizable sugar, will not granulate ; while other samples mixed with glucose will granulate. The light-colored and best grades of honey will be fine-grained ' in granulation, while other grades will be coarse-grained and present the appearance of sugar for certain to the uninitiated. When an honest man falls into an error, he is always willing to correct it as soon as it is pointed out to him and proved to be such. Prof. Wiley was expected to do that much at least toward repairing the injury he had wittingly or unwittingly done the whole fraternity of bee-keepers. But Prof. Wiley failed to do so, so far as the public knows. He neglected — I may safely say refused — to make the amende honorable. The apiarists became incensed, indignant, and demanded proof of his assertion or a retraction. The professor of science vouchsafed neither the one nor the other. Finally, after years had elapsed, being still hotly pursued by the apiarists and bee journals, especially the Ameri- can Bee Journal, Prof. Wiley did manage to make an explana- tion or "statement"; which, however, in no way improved his position before the public either as an honorable man or a pro- fessor of science. About seven years after uttering the slander to the world, he speaks, and makes this astounding admission : " At the time, I repeated this statement more in the light of a pleasantry than as a commercial reality, for I did not believe that it was possible commercially to imitate the comb." (Letter dated Washington, D. C, May 29, 1888, addressed to W. M. Evans, and published in the American Bee Journal of June 13, 1888.) In this attempted justification of himself Prof. Wiley says he had heard from a friend of his (now deceased) that comb-honey 74 THE POPULAR SCIENCE MONTHLY. was manufactured in Boston as stated above. On the strength of that, and that alone, he made the deliberate assertion which I have quoted from The Popular Science Monthly. Now, after reading and re-reading the context in The Popu- lar Science Monthly article, I find not a shadow of evidence that this statement was meant for a fiction and not for a fact. It is given seriously and deliberately, along with other alleged scientific facts, with no intimation or indication whatever of its spurious character. The readers (and no doubt the publishers) of The Popular Science Monthly accepted the statement in good faith as a fact. The newspapers, of course, accepted it as true from so respectable an authority as The Popular Science Monthly, and even the encyclopaedias finally took it in. Indeed, nobody, it seems, took it as a fictitious " pleasantry," or even dreamed it was meant for one, till the exigencies of the case required such a con- struction (or misconstruction) from the author himself. If it really was meant as a harmless scientific squib, with no malice 'prepense, the question arises, How is it that the professor neg- lected to set the matter right when he found that everybody was taking his joke seriously, to the great detriment of an important industry, and the calumnious aspersion of honest honey-pro- ducers ? Another example of spurious science is now before me. The Medical Standard for June, 1889, contains a leading article on Embryology, by a learned New York doctor, in which we are gravely informed that " a worker bee is a highly organized creat- ure, with a well-developed brain, wonderful sense-organs, intricate muscular apparatus, and yet it is an offspring of an unimpreg- nated queen bee." Now, this is all well put and quite true, except the last clause, which is just the opposite, of the truth. Any apiarian specialist could have told the doctor that while it is true that the virgin queen bee lays eggs which produce drones or males, she never deposits eggs which produce females — that is, workers and queens — until after she is impregnated by the drone. Hence, the worker bee is not " an offspring of an unimpregnated queen bee." "While it would be obviously unfair and unreasonable to hold the Monthly morally responsible for the specimen of wily science and its results to which this article refers,- it is, perhaps, not en- tirely free from blame in allowing the matter to rest uncorrected so long. I take the liberty of here suggesting to publishers of encyclopaedias and scientific works the wisdom of first submitting doubtful points and dubious assertions, made by men outside their special departments, to practical men in such departments, whether the latter be learned or unlearned, for the knowledge of an unlearned man touching his own particular line of business WALLACE OX "DARWINISM." 75 (even the science of it) may exceed that of the scientist both in accuracy and extent. Such a course would often save the special- ist from humiliation, and spare the* public the infliction of some very queer science, which, not infrequently, fails to dovetail with every-day facts. •»•» I WALLACE ON "DARWINISM." By the LORD BISHOP OF CAELISLE. HAVE read with deep interest, as doubtless have many other persons, Mr. Wallace's volume entitled Darwinism, which appeared in the month of March last year. No one has a higher right to teach the world on this recondite subject ; and when it is borne in mind that Mr. Wallace was himself an independent dis- coverer of the principle associated with the name of Darwin, and that, nevertheless, no sentence indicative of rivalry or jealousy — in fact, no sentence laying claim to original discovery — occurs throughout the book, it is impossible not to be struck with a feel- ing of reverence toward a writer who combines such remarkable ability with no less remarkable modesty. Reference is made to this point in an article in the Contemporary Review (August, 1889) by Prof. Romanes, who writes thus : It was in the highest degree dramatic that the great idea of natural selection should have occurred independently and in precisely the same form to two work- ing naturalists ; that these naturalists should have been countrymen; that they should have agreed to publish their theory on the same day ; and last, but not least, that, through the many years of strife and turmoil which followed, these two English naturalists consistently maintained toward each other such feelings of magnanimous recognition that it is hard to say whether we should most admire the intellectual or the moral qualities which, in relation to their common labors, they have displayed. Prof. Romanes further lays stress upon the fact that, whereas opinion has lately tended, as between the two naturalists, toward Wallace and away from Darwin, there is no sign of triumph in the book. If ever there was an occasion (writes Prof. Romanes) when a man of science might have felt himself justified in expressing a personal gratification at the turn- ing of a tide of scientific opinion, assuredly such an occasion is the present ; and, in whichever direction the truth may eventually be found to lie, historians of science should not omit to notice that in the very hour when his life-long belief is gaining so large a measure of support, Mr. Wallace quietly accepts the fact with- out one word of triumph. It is very pleasant to read this record of forgetfulness of self in the feeling of complete devotion to the cause of science and of truth ; possibly instances of such self -forgetfulness are not so un- common as they are sometimes supposed to be. 7 6 THE POPULAR SCIENCE MONTHLY. But Mr. Wallace needs no compliments from me, and it is not for the purpose of paying them that I have taken pen in hand. My purpose is rather to commit to paper certain thoughts which have occurred to me during the reading of his most interesting volume, and which it may perhaps be worth while to record. It seems to me that the publication of Mr. Wallace's work affords an occasion for taking stock, as it were, of that which the author describes as "Darwinism." It is needless to say that in the author's use of the word there is nothing vague, much less dis- paraging, in this term. The term is used in a certain definite sense, and is intended to express, not evolution in general, but evolution by those special processes to which Mr. Darwin believed evolution to be due. It is, I think, manifest that much advantage may accrue even from a declaration at the hands of such an authority as Mr. Wallace of what " Darwinism " is ; but, besides this, it is specially advantageous, now that a quarter of a century has passed since the great revolution in thought on this class of subjects commenced, that we should know what is the real position of the controversy ; there has been sufficient time for the smoke and din of the battle to pass away, and we can now form a better estimate than was possible in earlier days of the actual result of the engagement. I propose, therefore, to offer some remarks upon Mr. Wallace's volume, chiefly from the point of view just indi- cated; observing in general that the conclusion which seems to me to be of chief importance is this — that while Mr. Wallace holds to Darwin's views in the most important particulars, he does not regard " Darwinism " as any explanation of some of the most important phenomena which the living world presents. This observation, however, must stand on one side for the present. The point which must occupy us just now is the actual meaning of '"' Darwinism," upon which possibly not a few persons have somewhat hazy notions. Let me quote Mr. Wallace : * In order to show the view Darwin took of his own work, and what it was that he alone claimed to have done, the concluding passage of the introduction to the Origin of Species should he carefully considered. It is as follows: "Although much remains obscure, and will long remain obscure, I can entertain no doubt, after the most deliberate and dispassionate judgment of which I am capable, that the view which most naturalists until recently entertained, and which I formerly entertained — namely, that each species has been independently created — is erro- neous. I am fully convinced that species are not immutable ; but that those belonging to what are called the same genera are the lineal descendants of some other and generally extinct species, in the same manner as the acknowledged varieties of any one species are the descendants of that species. Furthermore, I am convinced that natural selection has been the most important, but not the exclusive, means of modification." It should be especially noted, adds Mr. Wal- * Page 9. WALLA CE ON "DARWINISM." 77 lace, that all which is here claimed is now almost universally admitted, while the criticisms of Darwin's works refer almost exclusively to those numerous ques- tions which, as he himself says, will long remain obscure. Mr. Wallace then proceeds to explain precisely what is meant by natural selection, and what, therefore, the Darwinian theory really is : The theory of natural selection rests on two main classes of facts, which apply to all organized beings without exception, and which thus take rank as fundamental principles or laws. The first is the power of rapid multiplication in a geometrical progression ; the second, that the offspring always vary slightly from the parents, though generally very closely resembling them. From the first fact or law there follows, necessarily, a constant struggle for existence; because, while the offspring always exceed the parents in number, generally to an enor- mous extent, yet the total number of living organisms in the world does not, and can not, increase year by year. Consequently, every year, on the average, as many die as are born, plants as well as animals ; and the majority die premature deaths. They kill each other in a thousand different ways; they starve each other by some consuming the food that others want ; they are destroyed largely by the powers of nature — by cold and heat, by rain and storm, by flood and fire. There is thus a perpetual struggle among them which shall live and which shall die ; and this struggle is tremendously severe, because so few can possibly remain alive — one in five, one in ten, often only one in a hundred or one in a thousand. Then comes the question, Why do some live rather than others ? If all the individuals of each species were exactly alike in every respect, we could only say it is a matter of chance. But they are not alike. We find that they vary in many different ways. Some are stronger, some swifter, some hardier in constitu- tion, some more cunning. An obscure color may render concealment more easy for some, keener sight may enable others to discover prey or escape from an enemy better than their fellows. Among plants the smallest differences may be useful or the reverse. The earliest and strongest shoots may escape the slug ; their greater vigor may enable them to flower and seed earlier in a wet autumn ; plants best armed with spines or hairs may escape being devoured ; those whose flowers are most conspicuous may be soonest fertilized by insects. We can not doubt that, on the whole, any beneficial variation will give the possessors of it a greater probability of living through the tremendous ordeal they have to undergo. There may be something left to chance, but on the whole the fittest will survive* Upon this statement of what " Darwinism " is, coming to ns as it does from the highest authority, certain observations suggest themselves. In the first place, objection may be taken to the phrase, the fittest will survive. The phrase, if I am not mistaken, was not originally devised by Mr. Darwin, and seems open to criticism. For fitness implies something of moral superiority ; you can not measure it in respect of length, or breadth, or strength, or any other quality capable of being tested by strictly physical condi- tions. Moreover, there is some danger of being betrayed by the * Pages 10, 11. 7 8 THE POPULAR SCIENCE MONTHLY. phrase into the error of arguing in a circle ; for, in the case of not a few creatures which have survived, it is difficult to give any good reason for their survival except upon the assumption of their fitness as proved by the very fact of their survival. Thus their fitness leads to their survival, and this survival leads to the conclusion that they must have been the fittest. Which is argu- ing in a circle. Still further, it is not difficult to suggest exam- ples in which the expression, survival of the fittest, manifestly breaks down. Sir Isaac Newton was, as is well known, a very delicate child, difficult to rear. Suppose that Newton and a pow- erful navvy, or coal porter, or grenadier, had been compelled to rough it as children at Dotheboys Hall or some similar establish- ment, which would have survived ? Not Newton ; and yet it may be fairly argued that in many respects he would have been the fittest. Nor is this imaginary case an altogether unfair test of the propriety of the phrase ; for it is impossible to give any true defi- nition of fitness which shall exclude all moral and intellectual qualities, all qualities in fact which are of the highest value, and which shall simply include those elements of toughness and wiri- ness, and strength of sinew or stomach, which are chiefly calcu- lated to prolong life in trying circumstances. Putting out of consideration, however, the propriety of the language by which survival in the struggle for life, whether among vegetables or animals, is expressed, it is to be admitted that the principle indicated is a true one. That is to say, it may be regarded as admitted by all persons whose studies and natural powers render their opinion of any real value, that modification by natural selection is an element in that evolution of living forms of which the evidence appears to be irresistible. Natural selection is a vera causa ; the question is, What is the extent of its action ? how much can it do ? Darwin considered it necessary to supplement natural by that which he termed sexual selection ; in doing which he was quite consistent, because he speaks (as we have already seen) of natural selection as " the most important, but not the exclusive, means of modification " of species. This supplemental hypothesis, however, does not commend itself to Mr. Wallace's judgment. Mr. Darwin (he writes), as is well known, imputed most of the colors and varied paterns of butterflies' wings to sexual selection — that is, to a constant preference, by female butterflies, for the more brilliant males ; the colors thus produced being sometimes transmitted to the males alone, sometimes to both sexes. This view has always seemed to me unsupported by evidence, while it is also quite inadequate to account for the facts. Again, after explaining his own views on the subject of orna- mental appendages of birds and other animals, he writes : The various. facts and arguments now briefly set forth afford an explanation WALLACE ON "DARWINISM." 79 of the phenomena of male ornament as being due to the general laws of growth and development, and make it unnecessary to call to our aid so hypothetical a cause as the cumulative action of female preference.' Whether the views put forward by Mr. Wallace do in reality- render unnecessary the Darwinian hypothesis of sexual selection will not be here discussed ; it is sufficient to note that the conclu- sions of Mr. Darwin in this not unimportant matter have, after abundant time for examination and reflection, been rejected by the naturalist who more perhaps than any other has a right to criticise him. But Mr. Wallace rejects also the evolutionist views of another very competent naturalist, Prof. Romanes ; and it will aid in the development of the purpose of this paper if I refer in passing to this rejection. The theory of Prof. Romanes is described by him under the phrase physiological selection ; it is not necessary in this place to explain what the theory is ; it is sufficient to say it is regarded as highly important by Prof. Romanes, and as utterly unfounded by Mr. Wallace. It would be impertinent on my part to offer any opinion as between these two authorities; but the conclusion may be fairly drawn that there is probably much at present unknown in the subject of evolution, as well as not a little doubt with regard to some fields of inquiry into which our knowl- edge is supposed to extend. But the most striking and interesting feature of Mr. Wallace's book, from what I may describe as the human point of view, is to be found in that part of his work in which he denies, and (as he believes) proves himself to be justified in denying, the application of the principle of natural selection to the evolution of the human faculties. This denial is a fact of the first order of magnitude ; and I confess that I can see no ground for the language of strong depreciation in which Prof. Romanes, in the article already re- ferred to, describes this portion of Mr. Wallace's book. He speaks of the substance of the concluding chapters as being " sadly like the feet of clay in a figure of iron, marring by its manifest weakness what would otherwise have been a completed and self- consistent monument of strength." No argument in the article justifies this condemnation ; and it is, perhaps, not too much to say that many of his readers will find in the condemned portion of Mr. Wallace's book that which has the deepest interest for themselves, while it must not be forgotten that the views put forward are alleged by Mr. Wallace to rest upon proofs which he formally submits for examination. Let us see, then, what this clay formation contains. Mr. Wallace fully accepts " Mr. Darwin's conclusion as to the essential identity of man's bodily structure with that of the higher mammalia, and his descent from some ancestral form common to 80 THE POPULAR SCIENCE MONTHLY. men and to the anthropoid apes." But he observes that u although perhaps nowhere distinctly formulated, his (Mr. Darwin's) whole argument tends to the conclusion that man's entire nature and all his faculties, whether moral, intellectual, or spiritual, have been derived from their rudiments in the lower animals, in the same manner and by the action of the same general laws as his physical structure has been derived/' This conclusion Mr. Wallace con- siders to be " not supported by adequate evidence, and to be di- rectly opposed to many well-ascertained facts." I will not endeavor to reproduce the whole of Mr. Wallace's argument on this subject, but will present what appears to me to be the pith of it; and I do this with the greater satisfaction, because what is here advanced seems to harmonize with what I have already written in criticising the phrase survival of the fittest. Let us confine ourselves, for simplicity's sake, to one human faculty, namely, the mathematical. The problem is, how to pro- duce a mathematician by the process of natural selection. The reader must bear in mind clearly what the theory of natural selection is, as already expounded. It is the survival in the strug- gle for life of those individuals which possess variations from their fellows favorable to their preservation. In order, therefore, that the mathematical faculty should be evolved by the process of natural selection, it is necessary to suppose that those individ- uals, which have an advantage in the possession of rudimentary mathematical faculties somewhat in excess of their fellows, should be the survivors in the struggle for life. The mere possession of this rudimentary advantage must be an aid toward life preser- vation. This in itself is hard to understand ; but it becomes harder still when we bear in mind the rareness of the mathe- matical gift. In our own time it would be perhaps an over- estimate to say that the mathematical faculty existed in any marked degree in one per cent of the population; assume such a proportion to have generally held in human history, then it would be necessary to suppose that these rare specimens of rudi- mentary mathematical ability had some very decided advantage in the struggle for life : but what ground is there for such a sup- position ? Grant that ten men in a tribe of a thousand had dis- covered how to count upon their fingers, or suppose them to have discovered some elementary geometrical theorem, how would this help them when a neighboring tribe attacked them, or when fam- ine and pestilence were abundant ? It is difficult or impossible to say. And the same argument would seem to apply to other human faculties, music and all forms of art, writing, even speech. Con- sider speech for a moment as the most universal and most dis- WALLACE ON "DARWINISM." 81 tinctive of human faculties. Here the problem is just the reverse of that which occurred in the case of mathematics : in that the favorable variation to be preserved is rare, in this the variation scarcely exists ; the faculty of speech is universal ; how, then, can there be a survival of the fittest where all are equally fit ? It seems difficult to resist this kind of argument, and I should not be surprised to find the opinion gain ground, and ultimately become established, that while the human faculties have undoubt- edly been developed gradually, the development can not in any way be traced to the process of natural selection. But if it be once admitted that the principle of natural selec- tion is inadequate to explain the development of specially human qualities, there is a temptation to go back to the consideration of the powers and instincts of some of the inferior creatures, and to inquire whether natural selection may not be inadequate also in their case, as in that of man. I confess that I have never been able to perceive how the principle can be brought to bear upon such phenomena as the architecture of insects — for example, that of bees and wasps. What, I suppose, ought to have happened is this, that some variation of an ancient form of bee made a rough approximation to a modern honeycomb, that they who made the best honeycomb were the fittest to survive, and that in this way by slow degrees and by natural selection a race of bees was pro- duced capable of performing the geometrical wonders which mod- ern bees perform. But there are two difficulties : First, in con- ceiving the original start of insects in the direction of architect- ure ; and, secondly, in perceiving the connection between good architects and survival in the struggle for life. Certain bees might make their wax go further than other bees, and our actual bees use their wax with absolutely mathematical economy ; but it is difficult to perceive how this economy is helpful in the struggle for life. Can we get over these difficulties ? If it were a case of some device for self-preservation, the conclusion might be differ- ent. For example, if we can imagine some variation of a race of spiders devising, in ever so rough a form, those curious houses which have attained such perfection in the hands of the trap-door spider, we can also easily believe that this variation would be likely to survive, and that while less ingenious spiders became the prey of their enemies, those which were concealed in their cunning castles would escape. But there is nothing parallel to this in the case of wasps and bees ; here we have a beautiful geo- metrical problem somehow solved, apparently without connection between the solution and the preservation of life. One of two conclusions seem inevitable — either the geometrical skill has be- longed in its perfection to bees and wasps ever since those insects existed ; or else the geometrical skill has been developed by some VOL. XXXVII. — 6 82 THE POPULAR SCIENCE MONTHLY. internal law of 'growth, independently of all questions of natural selection. There is another class of natural phenomena upon which Mr. Wallace writes much that is deeply interesting, but to which it may possibly be questioned whether the principle of survival by natural selection is applicable — namely, the phenomena of mimic- ry. Of course it is quite intelligible, to take an instance, that a living creature which is very much like a leaf will escape many enemies, and even have such an advantage in the struggle for life that many other living creatures would be like leaves if they could. But when we endeavor to go back in imagination to the commencement of the mimicking process, we must conceive of a creature not at all like a leaf, but among whose offspring there are certain individuals which have a slightly leaf -like appearance, and that these survive in preference to others not having the ap- pearance in question. The conception involves two difficulties : First, the notion of certain individuals having a slightly leaf -like appearance is eccentric and hard to accept. It is different from that of individuals varying by length of leg, or strength of wing, or what not. It is a variation, so to speak, not of degree but of kind. And, secondly, it is difficult to see why a resemblance to a leaf, admitted to be slight, and therefore one would imagine not easily perceived, should be any substantial protection from ene- mies, and so an appreciable advantage in the struggle for life. Similar difficulties occur with regard to other cases of mimicry. My space does not permit me to examine them in detail ; but I have come to the conclusion that, while mimicry may probably be always connected with some advantage which it confers on the animal, it is difficult to conceive of the mimicking transformation being originally brought into operation by any process of natural selection. This failure of the principle of natural selection to explain much that is connected with the evolution both of men and of inferior creatures may lead us to inquire, to what extent the prin- ciple satisfies etiological requirements even in those cases in which its application appears most complete. The modification and multiplication of species require three conditions to be post- ulated : (1) an original species; (2) the power of multiplying that species by reproduction ; and (3) the occurrence of variations in the successive generations. Now (1) the existence of the original living germ or germs must, I suppose, be left by universal consent in mystery. Mr. Darwin treated of the Origin of " Species," not the Origin of " liv- ing tilings" This latter question is not likely ever to come within the reach of human science ; certainly it has not done so yet. Given the existence of the material universe, or the existence of WALLACE ON "DARWINISM." 83 living things, and there is abundance of opening for discovery with respect tb the laws of matter and the laws of life ; bnt mat- ter and life must first be given : this is sufficiently obvious ; but it is worth noting, because there is sometimes a tendency to make a confusion between creation and the laws of created things ; whereas it is obvious that creation is one thing, and the law gov- erning created things is quite another. But (2) as the original existence of living things is a mystery, so also is the reproduction of them. The continuity of life on the earth's surface, insured in various ways more or less resembling each other, and all agreeing in this, that there is apparently no tendency in vital power to de- generate or wear itself out in the course of ages, is, as it were, a standing mystery of creation. The scientific man has nothing to do with this mystery ; to him it is simply a fact or phenomenon ; but he who tries to go beyond phenomena and to get at the cause behind them will recognize reproduction as being etiologically equivalent to continuous creation. The great feature, however, of the principle of natural selection is (3) the occurrence of varia- tions. Mr. Wallace lays great stress on the abundance of the variations which occur in nature, and the corresponding impor- tance of this element in the Darwinian theory ; and he is obviously wise in doing so. But it is well to observe that it is impossible to regard variations either on the one hand as a necessary feature of reproduction, or on the other as simply fortuitous. With regard to the latter supposition it is, certainly, difficult to conceive of chance as being a principal factor, say, in the production of a horse, to say nothing of a man. But even the former supposition is not quite an easy one : it is difficult to see why variations capa- ble of being made permanent should occur, and why (if there be offspring at all) the offspring should not be exactly like the parent ; in not a few cases this seems to be the law of living things. What I wish to point out, however, is this, that from the etiological point of view there ought to be a cause for variations as well as for other phenomena ; and that, therefore, when we use the phe- nomenon of variations as a part of the machinery of natural selec- tion, we do not get rid of the task of inquiring, as philosophers, why those useful variations occurred. In fact, in this as in many other instances, what is done is to shift the process one stage back- ward, but to leave the question of the primary cause very much where it was. Variations are abundant, says the student of natu- ral history, and advantageous variations are preserved and made permanent by the process of natural selection : let it be granted. But the philosopher may still say : How comes it that advan- tageous variations should occur ? Must not this occurrence be the result of some pre-established principle or law of development ? Take the case of the horse, which Mr. Wallace has dwelt upon 84 THE POPULAR SCIENCE MONTHLY. at some length, and has illustrated by a diagram. The evolution of the horse of historical times, and of the present day from the orohippus of the Eocene period, as exhibited to the eye by Mr. Wallace's diagram, is as interesting a presentation of a physical pedigree as can well be conceived. We see, as it were, the progress of Nature's work ; the transformation from several toes to one toe, which was, in reality, the operation of thousands of years, is visi- ble as a connected continuous process from beginning to end. But what the diagram does not, and can not, put in evidence is this — namely, the marvelous beauty of the horse in his ultimate con- dition. So far as any conclusions can be drawn from the diagram, the top and the bottom of the page stand upon an equal footing ; there would seem to be no reason why orohippus should not have been derived from equus by expansion, as easily as equus has been derived from orohippus by contraction. When, however, we look, not at the equus of science, but at the horse of the hunt- ing-field or the race-course, or at our own stable friend, who has carried us safely for hundreds of miles, we perceive that, somehow or other, we have, in these modern days, an animal of the most perfect kind with regard to speed, beauty, and mechanical perfec- tion. We feel convinced that it would be in every way a mistake that he should develop toes and become orohippus ; we are sure that orohippus has rightly been improved off the face of the earth in order to make room for equus. All this is, in the best sense of the phrase, in accordance with the principle of the survival of the fittest ; but I confess that I find it difficult to realize the transfor- mation of orohippus into equus upon the pure and simple notion of advantageous variations in the struggle for life ; for, in truth, if the question be one of mere survival, it is difficult to say, when the earth was inhabited by wild creatures, in what manner the possession of one toe instead of three or four should give equus any advantage over orohippus. One can quite understand that a jury of Newmarket jockeys would decide that equus was fittest to survive ; but in the absence of human judgment the conclusion is not so easy to reach. At all events, it seems more probable that the transformation was originally ideally contained in the concep- tion of this class of creature, and that equus may be regarded as bearing to orohippus something of the same kind of relation as is borne by a frog to a tadpole, or by a moth to a caterpillar. May it not well be that predetermined transformation has as real a place in the genesis of species as it certainly has in that of individual creatures ? Nothing, perhaps, strikes most minds as more surprising than insect and reptile transformation. That a crawling animal should, by a complicated process, involving a condition of motionless helplessness, be ultimately transformed into a creature of active life spent in flying through the air, or WALLA CE ON "DARWINISM." 85 that toads and frogs should find it necessary to pass through the fish-like life of tadpoles — this class of facts may well puzzle the thinking mind ; but the advantage of them is that they are facts ; no one can dispute them ; and taking our stand upon them we may guess that the processes of Nature are analogous, in cases in which we can not distinctly prove that they are so. May it not be, then, that the Eocene period of creation presented a condition of things out of which a higher condition was evolved, not simply by the perpetuation of advantageous variations, but much more by virtue of an internal principle of growth, similar to, or at least comparable with, the principle which develops the foetus or which transforms tadpoles and caterpillars ? Adopting this view, we should have in both cases a limit toward which transformations tended ; as the butterfly is the ultimate form of the caterpillar, and the caterpillar was the forerunner and necessary ancestor of the butterfly, so equus may perhaps be regarded as the ultimate form of orohippus, and orohippus as the forerunner and necessary ancestor of equus. At all events, this view of the facts seems to be tenable, and it is free from certain difficulties by which the hypothesis of natural selection pure and simple is undoubtedly beset. The question of growth, evolution, development, by an internal power similar to, and comparable with, that which we see daily and hourly at work all round about us, leads to the discussion of another and very interesting question — namely, whether man can perfectly be described as " derived from the lower animals." The expression is Mr. Wallace's. He speaks of "man in his bodily structure " as having been " derived from the lower animals, of which he is the culminating development." * I venture to ques- tion whether this is a correct statement of the facts of the case. I am not venturing to throw doubt upon Mr. Wallace's scientific deductions ; on the other hand, their correctness shall for the sake of argument, if on no other ground, be fully granted ; all the more readily in consideration of the important limitations of the principle of natural selection made in the case of man, as already noticed and discussed. What I venture to doubt is, whether the process of human evolution, as accepted by Mr. Wallace, can be rightly described by the terms which he applies to it. Certainly there is something in the conception of such derivation from which the feelings of most of us not unnaturally shrink, and from which they would gladly be free, if freedom can be had consist- ently with scientific truth. There is something in it of that " let- ting the house of a brute to the soul of a man," of which Lord Tennyson sings in his most recent volume. It may be worth * Page 454. 86 THE POPULAR SCIENCE MONTHLY. while, therefore, to consider whether the phrase, " derivation from the lower animals," is one which can be maintained as rightly ex- pressing the truth which it is intended to express concerning the physical history of our race. Now it is manifest that if we look back, so far as is possible, into the remote past, when the first germ of animal life appeared upon the globe, two conditions of things, and two only, are con- ceivable. Either (A) there was a single germ of life, from which all subsequent living forms have been evolved or developed ; or (B) there were several or many germs of life, from which, in sepa- rate streams, so to speak, the evolution of living creatures took place. Mr. Darwin inclined, I think, to the latter supposition ; but either A or B must be accepted by all evolutionists of all schools. Let us consider them successively. A. If we make the supposition that living forms commenced upon the globe from a single germ, then it follows that all living creatures now existing — insects, fishes, birds, beasts, man — have been evolved by some process or processes from one and the same origin : whether the process of variation and natural selection be sufficient to account for the development, it is not necessary for the purpose of this argument to decide ; it is sufficient to say, and this can scarcely be denied, that by some process or processes the development has taken place. Therefore, ascending to the hy- pothesis now under consideration, it will be true that the lower animals and man had a common origin ; but this is manifestly a different thing from asserting that man is "derived from the lower animals." If we go up to the hypothetical origin of life, or the single germ, this latter assertion is obviously untrue, because, as by hypothesis there was then only one germ, there could be no distinction of superior or inferior ; but if we stop short of the ori- gin and observe the condition of things at any period subsequent to the hypothetical beginning, we shall find progress being made toward the development of man and simultaneous progress being made toward the development of the lower animals. But it does not follow that, because this simultaneous development is taking place, therefore we can say that one form of life is developed from the other ; it might be as correct to say that the inferior animals were developed from man, as man from the inferior animals. Take an illustration from that which is possible in the case of rivers. Conceive of two rivers running into the sea ; trace their course, and suppose that ultimately you come to the same source in the distant mountains ; it would not be correct to say that one of these rivers was derived from the other. The correct state- ment would be that they sprang from one and the same source, that they had different histories, and that they terminated in dif- ferent streams. WALLACE ON "DARWINISM." 87 When we speak of the lower animals, do we not in fact postu- late the existence of man ? Lower .than what ? Surely lower than man : therefore inferiority can not be predicated until man's existence has been assumed, or has become a fact ; and therefore to speak of man being derived from the lower animals in the remote past, when, if you only go far enough, there is no higher or lower, would seem to be a confusing use of language. If it be urged that the objection now made to the phraseology used by Mr. Wallace is merely a verbal quibble, I venture to argue, on the other hand, that there is not a little importance in the objection. I quite admit that if the creation of man be a merely fortuitous fact, a lucky hit, so to speak, in the infinite variety of living forms developed from a single original living germ — if, in fact, creation be without the high purpose which human life, as distinguished from all other forms of life, seems to make manifest — it is scarcely worth while to argue the question whether man was derived from the inferior animals or not. But if man be the intended crown of creation existing in the determi- nate counsel and foreknowledge of God from the beginning, then it does seem to be worth while to argue that the derivation of man and beast from the same living germ is not the same thing as the derivation of one from the other. A sane man may have the misfortune to have an idiot brother ; the sane man and the idiot are derived from the same parents, but it would be incorrect to say that one was derived from the other. May there not be some analogy between a case of this kind and the case of man and beast ? B. So much, then, for the hypothesis of one original germ of life ; the argument becomes perhaps more simple if we adopt the second hypothesis, namely, that of several or many germs. For in this case it is not unreasonable to suppose that specific differences existed among the original germs. I confess that the notion of the development of all forms of life from one original germ offers to my own mind an almost insuperable difficulty. The arguments drawn from the experimental facts of variation and natural selection, from the observed progression of animal forms in successive geological strata, and the like, seem to me quite inadequate to explain the development of insects, fishes, birds, mammals, from one stock. Consequently, to my own mind it is a relief to be able to think of several, and if of several then possibly of any number, of original germs. The hypothesis is not opposed to, but quite in accordance with, Mr. Darwin's own views ; in fact, he was far too cautious a man to dogmatize con- cerning the unity of the origin of living forms, when all attempt at the examination of the question of origin would necessarily carry him far beyond the limits of possible experiment. Let us 88 THE POPULAR SCIENCE MONTHLY. then adopt provisionally the hypothesis of a multiplicity of germs of life ; and if we do this, there is nothing wild or strange in the supposition that the germ of man was different from other germs. It would be beyond all that scientific caution would justify to assume that, given a number of original germs of life, it is matter of chance into what each will develop. It is contrary, I think, to the whole analogy of Nature to suppose that a living germ, which is to all intents and purposes an ovum or egg, may ultimately develop into an oak, or a fish, or a man, according to its surround- ings or according to mere chance. At all events, it is much more probable, much more according to analogy, that each germ should have its specific character, and that so man should have been man in intention and preparation from the very beginning of things. It may have been — in fact, according to the supposition of evolu- tion it must have been — that in the early condition of life upon the globe there was no man (in the full and proper sense of the word) in existence, but his progenitors would be there ; and what is submitted is this, that those progenitors were undeveloped men, and not " lower animals." What they visibly were scientific discovery has not yet put in evidence ; it is admitted that there is a " missing link " between the present and the past. Some sci- entific men hope that the link may be found, some think that it is hidden under the sea ; but, whatever the truth may be with regard to this point, what is maintained is this, that, on the hypothesis of a multiplicity of original germs of life, it is more probable than otherwise that certain germs contained the promise of men, others of " lower animals " ; and that, if so, it is incorrect to speak of the lower animals as the progenitors of men. This view of the case, though founded upon a criticism of Mr. Wallace's language, would seem nevertheless to be consistent with his real views concerning the origin of man. In the last chapter of his work, entitled Darwinism applied to Man, to which reference has been already made, it is contended, as we have seen, that the principle of natural selection will not account for the development of the human faculties. I recur to that chapter chiefly for the purpose of making two extracts, which will, I think, tend to strengthen the arguments which have been already advanced. After rehearsing three stages of progress in creation — the change from the inorganic to the organic ; the in- troduction of sensation or consciousness, constituting the funda- mental distinction between the animal and vegetable kingdoms ; and the existence in man of a number of his most characteristic and noblest faculties, those which raise him above the brutes and open up possibilities of almost indefinite advancement — Mr. Wal- lace writes thus : WALLACE ON "DARWINISM." 89 These three distinct stages of progress from the inorganic world of matter and motion up to man, point clearly to an unseen universe — to a world of spirit, to which the world of matter is altogether subordinate.* And again : Those who admit my interpretation of the evidence now adduced — strictly scientific evidence in its appeal to facts which are clearly what ought not to be on the materialistic theory — will be able to accept the spiritual nature of man, as not in any way inconsistent with the theory of evolution, but as dependent upon those fundamental laws and causes which furnish the very materials for evolution to work with.t Declarations such as these, coming from such an authority, must doubtless be very comforting to those minds which feel themselves compelled to receive the evidence for evolution but shrink from materialism, which feel convinced that materialism can not be true, and yet have an uneasy suspicion that evolution points to it as a logical conclusion. But if we admit with Mr. Wallace that variation and natural selection are not adequate to explain the evolution of man's higher qualities and faculties, we are not merely delivered from the acceptance of materialism, we are invited and even compelled (as has been urged in a former part of this paper) to review the whole question of the extent of the application of Mr. Darwin's great principle. He would be a rash man who, in the face of Mr. Darwin, Mr. Wallace, and the whole generation of naturalists who have followed in their steps, should deny that natural selection was a vera causa in creative work ; but there is no rashness or audacity in maintaining what Mr. Darwin did not deny, and what Mr. Wallace emphatically affirms, namely, that there is needed for the explanation of phe- nomena something beyond, and essentially different from, the process of natural selection. All seems to point beyond matter into the region of mind, beyond mechanical sequence to purpose, beyond all verai causm to the causa causarum, beyond Nature to God. I will close this paper by recording an incident which was communicated to me some years ago in the course of conversa- tion by Dr. Thompson, the late Master of Trinity College, Cam- bridge. Dr. Thompson was walking, in his college days, with two com- panions, one of whom was Alfred Tennyson ; of the name of the other I am not sure. The path by which they went was one which all Cambridge men know, namely, that which leads from the backs of the colleges through the fields toward Coton. After passing the brook, which used to be crossed (and perhaps is now) by a rude wooden bridge, it was perceived that Tennyson had * Page 476. t Ibid. VOL. XXXVII. — 7 9 o THE POPULAR SCIENCE MONTHLY, lagged behind. He had paused by the side of the brook, brought his eyes as near as he could to the surface of the water, and was examining with intense interest the subaqueous life which the lit- tle stream contained. After a time he rejoined his companions, and this was his utterance when he joined them : "What an imagi- nation God has ! * The words must have made a deep impression upon my informant's mind ; otherwise he would not have re- tained them in memory, and would not have thought it worth while to repeat them to me. They made a similar impression upon myself when so repeated ; and I can not but regard them as containing a true philosophy of Nature. Whatever may be the power of natural selection, and whatever causes may be at work to produce the varied scene of life which the world contains, you need some underlying cause, both of life itself and of reproduc- tion and variation, and of all natural phenomena ; and if causally the existence of the universe may be attributed to God's will and purpose, so the endless variety of vital manifestations may be attributed to that which in the case of man we should call imagi- nation. In reality, whatever may be the actual historical genesis of Nature, we seem to need a guasi-Platonic doctrine of antecedent ideas in the divine mind as the basis, the underlying condition, of the existence of things as we see them. It is matter for fair discussion among naturalists how much may be attributed to natural selection, how much to sexual, how much to physiologi- cal, and so forth. But such discussions can not go to the root of things ; they do not reach the original thought out of which the works of Nature, as we call them, originally spring. Michael Angelo, as we are told, used to sit with his hammer and chisel before his marble block, and shape it without any previous mod- eling process into the figure which he intended to produce ; other sculptors, I believe, with only this one grand exception, make their model in clay, and thence proceed by semi-mechanical steps to the finished work ; but Michael Angelo and all other sculptors have alike the seminal idea in their minds, and the manner of its evolution is comparatively a matter of detail. Something of the same kind may be said of the production of natural things. It may be possible for naturalists to discover some of the steps by which the finished work comes to be what it is ; but the actual origin of natural things — the wonders of life, the varied beauties of the universe, above all, the mind of man, which is capable of understanding, appreciating, and discussing the problems to which natural things give rise — is to be sought in no region lower than that which may, with all reverence, be described as the mind, or as the imagination of God.— Nineteenth Century. CATS AND THEIR FRIENDSHIPS. 91 CATS AND THEIR FRIENDSHIPS. By W. H. LAERABEE. I HAD for ten years a cat whose intelligence interested me greatly and was considered remarkable by all persons who took notice of her. Her confidence in her master and mistress, her evident enjoyment of their society, her happy faculty of put- ting herself upon an understanding with them, her familiar inter- est in matters of the household, the shifts and devices of which she was master, and her sagacity manifested in ways as various as the exigencies she had to meet, evoked frequent admiration and praise. These manifestations led me to look into the subject of knowledge in cats, and I have found that she was not singular, or even exceptional, in the quality of her faculties. She appears to have been a type to which a great many of the more happily trained members of her race can easily measure up. My observa- tions have been naturally extended to other animals, and have led to the conclusion that most domesticated species and many wild ones are capable of and often manifest equally high degrees of mental development. But cats — and dogs too — are more at home with us, have more opportunities to learn, and come under closer and more constant observation than the others. The cat belongs to a large and highly specialized family ; to one that is clearly distinguishable from the other families of ani- mals, while the resemblances between its own members is so strong that even the careless, unprofessional observer will hardly fail to assign at a glance an individual of any of its species to it. All the members of the family are, according to Wood, light, stealthy, and silent of foot, quick of ear and eye. They are ex- ceedingly graceful in form and movement, have flexible bodies and limbs — walk, we might say, on tiptoe — are alert and swift in action, and are exceedingly cunning. Between many of them and the cat itself there is hardly any prominently visible difference except in size. Curious resemblances in features of line or ex- pression may be remarked between the portraits of the Felidce in Wood's Natural History and cats with which the observer is acquainted. A copy of the photograph of the head and breast of a tiger at rest, in a portfolio by our side, might be easily mis- taken, except for a few differences in the shading of the hair, for a life-size portrait of the cat that has given the occasion of this article. St. George Mivart recognizes fifty living species of the cat family, forty-eight of which he includes in the genus Felis. The history of the domestic cat has been traced back to the ancient Egyptians, among whom the earliest notices of it appear 9 2 THE POPULAR SCIENCE MONTHLY. Fig. 1.— Egyptian Cat (Felis maniculata.) on the monuments of the second empire of the twelfth dynasty (about 2400 b. a), at Beni Hassan. It seems to have appeared there just after the Egyptians had made considerable conquests in Nubia, whence it may have been brought, already domesticated, among the spoils of war. The mummified cats in the Egyptian tombs are not identical with our house cat, but seem to belong to a native species (Felis maniculata, Pig. 1) which is said to be still in- digenous in Nubia, where it is found on the western side of the Nile, in a stony dis- trict in which brushwood grows. The domesticated animal was slow in making its way from Egypt into the neighboring nations. The Hebrews were ap- parently without it, and it is not once mentioned in the Bible. No evidence has been found that the Assyrians and Babylonians were acquainted with it. According to authors who have investigated the philological branch of the history, these people possessed a binary nomenclature for animals, with generic and specific names, and included their lions and panthers among the dogs — a thing they would hardly have done if they had been familiar with house cats. It was not known to the Greeks and Romans till a compar- atively late period ; and all the earlier representations of cats on their monuments are referred by the authorities to the wild cat or some other animal than the domestic cat. According to the most careful conclusions on this subject, the mouser of the Greeks and Romans was a weasel, and led an independent, not a domestic, life. The Aryans of India had cats at a very early but not at their earliest period ; for while the names of the animal are all Aryan, it was not, according to Pictet, designated by any simple term such as would have been given it in primitive times, but by composite names, having such meanings as "house-animal," " rat- eater/' and " mouse-enemy." The name of the wild cat (Fig. 2), however, embodied a root common to many of the European lan- guages. It becomes in Persian, pushak ; in Afghan, pishik ; in Kurdish, psiq; in Lithuanian, pnije ; in Irish, pus and feisag ; and in Erse, pusag and piseag ; whence the English "puss." It is derived by Pictet from a Sanskrit root puclilia or pitclilia, that means ''tail/' and therefore points to one of the most striking external features of the animal. The name by which the cat was known to the later Greeks — alXovpos — and which was origi- nally applied to the weasel, refers to the same feature. It is CATS AND THEIR FRIENDSHIPS. 93 Fig. 2.— Wild Cat (Felis catus.) compounded from two words that give the meaning of "wavy tail." The Latin name of the cat tribe (Felis) appears to have been originally applied to the weasel and other mousers, and after- ward to the wild cat. The word catus or cattus came into nse in about the fourth century, and is found first in the agricultural writer, Palladius, who recommends that cats be kept in artichoke- gardens for protection against mice and moles, and remarks that men had previously been served for this purpose by weasels. The name catta is found later in the Greek church histo- rian, Evagrius Scholasticus, about a. d. 594. Historical inferences have been drawn from the absence of the re- mains of cats in the ruins of Pompeii, and from the fact that the name common to all the other Romance lan- guages does not occur in Wallachian. It is concluded that the domesticated animal had not become common when Pom- peii was destroyed, in a. d. 79, or when Dacia was isolated from the rest of the Roman world by barbarian conquest, in the third century. Mr. W. Boyd Dawkins infers, from his researches in the caves in which the Celts took refuge from the Saxons, that cats were unknown in Great Britain before about the year 800. Cats easily commended themselves as efficient vermin-destroy- ers to such extensive grain-raisers as the ancient Egyptians ; and a people so ready to deify everything needed little prompting to put them in their pantheon. They may also have made them- selves useful in killing snakes, an occupation in which, if the sto- ries are true, they sometimes become very expert. Rengger, who has written of the mammals of Paraguay, declares that he has more than once seen cats pursue and kill snakes, even rattle- snakes, on the sandy, grassless plains of that land. " With their rare skill," he says, " they would strike the snake with their paw, and at the same time avoid its spring. If the snake coiled itself, they would not attack it directly, but would go round it till it be- came tired of turning its head after them j then they would strike it another blow, and instantly turn aside. If the snake started to run away, they would seize its tail, as if to play with it. By virtue of these continued attacks they usually destroyed their enemy in less than an hour, but would never eat its flesh." Cats are represented on some of the Egyptian monuments as accompanying their masters on hunting expeditions. In a wall- 94 THE POPULAR SCIENCE MONTHLY, picture on a tomb at Gurneh, a hunter is represented in his boat in the marshes as about to hurl his throw-stick at a covey of birds, while a cat by his side is on the alert to spring upon the game he is expected to bring down. Another picture (Fig. 3) rep- resents the cat seizing a bird. This would involve going into the Fig. 3.— An Egyptian Fowling Scene. 1. Sportsman using the throw-stick. 2.

Fishes, the emblem of water. water, an act to which our modern cats usually have a very strong dislike. If the Egyptian cats had the same feelings, they must have come under the discipline of skillful trainers. But there have been fisher cats in modern times. Mr. Ross, in his Book of Cats, tells of one that lived in 1829, which caught fish with great assiduity, and frequently brought them home alive. She taught another cat to fish, and they used to go out together, sometimes taking opposite sides of the river. Another story is quoted by the same author, of a cat at the battery in Plymouth, England, that was in the habit of diving into the sea, bringing up fish, and leaving them in the guard- room for the sailors. She was seven years old, and " as fond of the water as a Newfoundland dog," and hunted regularly along the rocks at the water's edge for her game, " ready to dive for it at a moment's notice/ 7 A cat described by Mr. Lawson Tait was a remarkable fisher, and would Domestic.

Mr. Harrison Weir * tells of a cat which used to go into the water up to her shoulders to bring in the fish which her master drew up with the hook, and which stole out the minnows that had been placed, for safe keeping, in a well of cold spring-water. The domestic cat is not identical with the Egyptian cat, and, therefore, if descended from it, must have undergone modifica- tions in the process. It is not known whether it has interbred with the wild cat ; but it is possible that some of the varieties have originated in that way. The marks of difference between the species are very plain. The most obvious one is the shape of the tail (Fig. 2), which in the domestic cat is long, slender, and tapering, while in the wild cat it is shorter, stumpy, and bushy. The fact that no tendency has been observed in either of these Fig. 5.— Mrs. Scott's English Taebt " Coppa." First Prize at the Crystal Palace Cat Show, 1886. forms of tail to revert to the other is in favor of a permanent specific difference. The minor varieties of cats are numerous, but the important ones are not many. A line is drawn between the short-haired and the long-haired varieties. Of the former are the tabbies (Figs. 5 and 10) — brown, blue, or silver ; red and spotted tabbies — of various colors, with their delicate stripings, cloudings, or spots ; the Chartreuse, blue, or Maltese, which has long, slate- colored fur, and a bushy neck and tail ; the Spanish, or tortoise- shell (Fig. 11) — white, black, and reddish-brown, mixed, whose Our Cats and all about Them. Boston and New York : Houghton, Mifflin & Co. 9 6 THE POPULAR SCIENCE MONTHLY. closer resemblance than that of the others to the Egyptian cat has suggested that the animal may have come to Europe by way of the Strait of Gibraltar ; and the Manx (Fig. 6), a curious variety, says Wood, on account of the entire absence of a tail, the place of which member is only indicated by a rather wide protuberance. " It is by no means a canny animal, for it has an unpleasant, weird-like aspect about it. ... A Manx cat, with its glowing eyes and its stump of a tail, is a most unearthly-looking beast." The manner in which its peculiarity has been perpetuated has not been accounted for. The long-haired cats include the Persian (Fig. 7), a gray -blue and silky animal, having a tail of great length and covered with hair six inches long, which it carries arched over its back like a squirrel's ; and the Angola, a beautiful animal, and knowing it — fig. 6,-manx cat. "gorgeous in its superb clothing of long, silky hair and bushy tail." It is one of the largest of domestic cats, and one of the heartiest eaters. Then there are the Chinese cat, large, with fine, glossy hair and hanging ears ; the royal cat of Siam (Fig. 8), clear tawny or buff, with black muzzle, face, ears, and feet, suggesting the figure of a pug dog ; black cats, which belong among the tabbies; and white cats, concerning which the belief prevails that if they also have blue eyes they are deaf. This connection has been accepted by Mr. Darwin as an in- stance of correlated variability, and is explained by Mr. Lawson Tait — the white color or albinism being regarded as a result of arrested development — by the fact of the common origin in the epiblast of the three structures affected — the fur, the iris, and the tympanic membrane. The bent of the cat's mind was pleasantly defined a few years ago by a writer in the London Spectator, who said there could be no doubt as to the view Puss took of the philosophy of nature and life. She is quite satisfied that the world and everything in it were made and exist for cats. This appears in all that well- bred and cared-for cats do, and in every accent and tone of their voice. Puss possesses herself with the air of a proprietor of the best place and the best food ; expects to be waited upon ; demands a share of every dish ; and looks upon us as at once her Provi- dence and her servant. Cats are not demonstrative like dogs, and do not submit to training like the horse. The dog has been credited with un- bounded affections, and the horse with almost human sagacity ; CATS AND THEIR FRIENDSHIPS. 97 but the cat still suffers under the bad character that Buffon — who can not have been acquainted with any reputable specimens of the race — gave her. She is said to be selfish, spiteful, cruel, crafty, treacherous, loving places and not persons, and in every way unworthy of fellowship in the household. J. G. Wood an- swers these accusations by saying that the cats with which he has been most familiar " have been as docile, tractable, and good- tempered as any dog could be, and dis- played an amount of intellectual pow- er which would be equaled by very few dogs, and surpassed by none." To all per- sons who have given their confidence to Puss and received hers in return, they need no answer. Numerous traits of the sort that make all the world kin ap- pear in the cats — human-like qualities and affections that bring them into sym- pathy with their mas- ters. Such traits will be made manifest to any one who even partially takes Puss into fel- lowship ; and whoever puts himself on good terms with her will find his association marked by wonderful examples of intelligence and affection, and will be ready to declare that there is no cat like the particular one with which he is dealing. The declaration will be true in a measure, for individuality is one of the most conspicuous traits of the species. A considerable literature has been written in demonstration and illustration of the more pleas- ing aspects of feline character, on which I have drawn for inci- dents from works that will be mentioned in course; and more freely from articles on animal intelligence in Nature and the Re- vue Scientifique, and from a Cat Competition, organized several years ago by the Republican Journal, of Belfast, Maine, in which many contributors gave the stories of their pets. Evidences are afforded in these observations of the habitual exercise by cats, in the ordinary course of their lives, of such qualities as recognition of their friends and attachment to them, capacity to form friend- Fig. 7, -Mrs. Valance's Persian, " Fluffy II." Cat Show, 1886. Crystal Palace 9 8 THE POPULAR SCIENCE MONTHLY. By per- Pub- ships with men and animals, exercise of self-denial, willingness to do favors or to help, understanding of language, ability to make their wants intelligibly known, humor, foresight, knowledge of right and wrong, the use of means to ends, capacity to adapt means to circumstances, the time-sense, and many other forms of intelligence. Lindsay, in his Mind in the Lower Animals, shows also that they, with other brutes, are liable to mental diseases not unlike those to which the human mind is subject. Thoophile Gautier, remarking on the difficulty of conquering the friendship of a cat, says that " she is a philosophical animal, orderly, quiet, tenacious in her habits, a lover of order and propri- ety, and one who does not bestow her affections blindly. She will gladly be your friend if you are worthy of it, but not your slave. In her tenderness she regards her own free will, and will not do for you what she judges to be unrea- sonable ; but once she has given herself to you, what absolute con- fidence, what fidelity of affection ! " Wood says that there is per- haps no animal so full of trust as a cat that is kindly treated, as there is none which, when subjected to harshness, is so nervously suspicious. Cats keenly recognize these distinctions in character, even among members of the same family, and govern themselves accordingly. Pertinent to this point is the newspaper squib of the maid who told her master that she knew Tom had returned from school, though she had not seen him, because the cat was hiding under the stove. 1 Tad," of Burnham, Maine, used to meet his master, a night watchman, every morning at the store-door, and accompany him home. After the master died, " Tad *' continued to go for him and wait ; then, not finding him, would return home and wander about the house as if in search of him. " Hannah/' of North Monroe, Maine, began to take care of the baby as soon as it came ; increased its attentions when the child could walk ; would go after him and call him back when he started to wander out of bounds, and then go to the house and mew for help till some one came to take the truant in charge. "Thomas," of Sandy Point, Maine, was accustomed to be fed with crumbs from the table by a single Fig. 8.— Mrs. Vyvtan's Rotal Cat of Siam.

My cat in like manner nsed to look to her mistress and to no other person for tidbits from the breakfast-table. " Daisy," of Belfast, who stayed with her mistress during an illness, missed her from the room and went out to look for her. Meeting her unexpectedly, she looked np, says the mistress, " as frightened as if she had seen a ghost. My voice, however, reassured her, and, if ever a cat smiled, I am sure she did." Another cat of the Belfast group, not a favorite and shy toward all other persons, became attached to a sickly infant and its faithful nurse, never failing to respond to its cries by going to its cradle and soothing it by purring and caresses till it became quiet. The cat of M. Arbousset, a French missionary in Africa, refused food when the child to which it was attached died, sought and mourned for its friend in a marked manner, and in a few days was found dead on its grave. The suggestion has been made, and is worthy of con- Fig. 9. — Archangel Blue Cat. By permission, from Harrison Weir's Our Cats and all about Them. Published by Houghton, Mifflin & Co., Boston and New York. sideration, that when pets die in this way soon after their human companions, it may be because they caught the disease from them rather than from intensity of affection. But this can not apply to the cat told of in the Leisure Hour, which, when the child its playmate died, refused food at first, but afterward, having found its companion's grave, spent most of its time there, going to the house for its meals. A critic, in the Saturday Review, claims to have known more than one instance of a cat, ordinarily con- stant to its own habits of comfort, breaking through its self-made rules to sit outside the door of an invalid as if waiting for news. The Rev. J. G. Wood's " Pret " was capable of the most earnest manifestations of gratitude. One day, when, having been forgot- ten, she had become very hungry, she flew " like a mad thing " at the meat and milk her master gave her ; but hardly lapped a drop before she went to him purring loudly and caressing him to express her thanks ; then went to the plate, " but only just touched lOO THE POPULAR SCIENCE MONTHLY. her nose, and again came to thank me " — actually refraining from enjoying the food she was so much in want of till she had repeat- edly acknowledged her obligations for it. A story is quoted by Mrs. Cashel Hoey from the London Spectator, of " Nero/' who, loving all the family and showing his love for each in different ways, especially loved his master, and was usually the first to hear his step. He could distinguish the click of his master's door-key, and would run to answer it ; was distressed if his master failed to return at evening, and would go look for his portmanteau, to see if that was gone too — that being his sign that master was taking a journey. If the portmanteau was in its place, he was satisfied ; if not, he would lie down and refuse food. If he knew the master was going away, he would try to hide himself in the cab ; and if mas- ter appeared with his hat on in the day- time, supposing he was going out, would try to take it off ; but if at night, was con- tented, for master had come home. The cat's strong attachment to its home, and indispo- sition to change it, are not peculiar to it, but are common to all animals, includ- ing man. The trait is often manifested, and sometimes in remarkable ways, in dogs, horses, and cat- tle. In man it is fre- quently illustrated in the affection known as " homesickness." The ability which animals display un- der its influence in finding their way back to their old accustomed haunts from long distances and by difficult or tortuous ways, or even by roundabout roads, when return over the direct route (as when it includes the crossing of bodies of water) is impossible, is the wonder of naturalists, and up to this time one of the unsolved Fig. 10.— Finely Marked Spotted Tabby Cat.

It has received the name of " the homing instinct/' and is regarded by some naturalists as constitut- ing an additional sense. The dog seems usually to be more ready than the cat to follow his master in a change of home, and to recon- cile himself to the new place, but this may be because he stands in a different relation toward him. The dog is sure of at least one fast friend wherever he lives, while the cat can not always reckon even upon that. In many families, where she is tolerated, as, according to Buffon, only because she is less objectionable than the rats and mice, she has no one to caress her or show affection to her. In this case, when her situation is barely endurable, she naturally fixes her attachment on the place where she has found cozy retreats and knows all the hunting-grounds, rather than upon persons who have given her no consideration, and of whom she perhaps stands in fear. Whether the cat will in the long run prefer its old home, deserted or inhabited by strangers, to a new home, along with the persons it has been accustomed to meet, may depend very much upon the treatment it has received from those persons. My cat was removed three times in ten years ; and, aside from the temporary embarrassment caused by finding herself in a strange place, readily adapted herself to the new quarters, and showed no disposition to go back to the old haunts. Lindsay, in Pig. 11.— Finely Marked Tortoise-Shell Cat. By permission, from Harrison Weir's Onr Cats and all about Them. Published by Houghton, Mifflin & Co., Boston and New York. his Mind in the Lower Animals, refers to cases of cats following their masters from house to house, from place to place, and accom- panying them on visits to other people's residences, as uncon- cernedly as a dog. Wood tells of a family on the coast of Scot- land who removed to the opposite shore — sailing around instead of crossing the country — leaving their cat with a neighbor. But the animal followed them, and found them in some way, present- ing itself after a few weeks at their door, " weary, ragged, and half starved." It had left its old home and gone out into the unknown to seek the family with whom it had lived. A case pre- 102 THE POPULAR SCIENCE MONTHLY. cisely similar, except as to the local topography, is related in Chambers's Journal, of a cat in a military chaplain's family at Madras. This animal also, having found its old friends on the other side of the city, several miles from their former home, went back and brought her kitten. Some of the incidents bear- ing upon this feature have an aspect of eccentricity. The young cat of a neighbor of the writer's disappeared from the house and was not found or heard of for six months. At the end of that time it returned and made itself at home at once, but grown and so changed that, though its familiarity was remarked upon as singular, it was not recognized till its identity was accidentally established by the discovery of a peculiar though obscure mark. Dr. A. Corriveau tells in the Revue Scientifique of a cat which was lost in a similar way. Five months afterward it was found in the house by the side of its companion, travel-soiled but plump, and recognizable by a red spot on its forehead. It had a very pleasant visit with its old mate and friends for a week, and then disappeared as unaccountably as it had done before. It is told in the Life of Sir David Brewster, by his daughter, that a cat in the house entered his room one day and made his friendship in the most affectionate manner — "looked straight at him, jumped on his knee, put a paw on each shoulder, and kissed him as distinctly as a cat could." From that time the philosopher himself provided her breakfast every morning from his own plate, till " one day she disappeared, to the unbounded sorrow of her master. Nothing was heard of her for nearly two years, when Pussy walked into the house, neither hungry nor thirsty nor foot-sore — made her way without hesitation to the study — jumped on my father's knee — placed a paw on each shoulder — and kissed him exactly as on the first day." These incidents pertain to only one of the human-like traits that have been named as to be found in cats. The study to which they introduce us is an alluring one, and opens the more expan- sively the further we proceed in it. Prof. Mendelejeff, in his Royal Institution lecture, found an analogy between the unseen world of chemical changes and the visible world of the heavenly bodies. Our atoms, he said, form distinct portions of an invisible world, as planets, sat- ellites, and comets form distinct portions of the astronomer's universe; "our atoms may therefore be compared to the solar system, or to the systems of double or of single stars ; for example, ammonia may be represented in the simplest man- ner by supposing the sun nitrogen, surrounded by its planets of hydrogen, and common salt may be looked upon as a double star formed of sodium and chlorine. Besides, now that the indestructibility of the elements has been acknowledged, chemical changes can not otherwise be explained than as changes of motion; and the production by chemical reactions of galvanic currents, of light, of heat, of pressure, or of steam-power, demonstrates visibly that the processes of chemical reaction are inevitably connected with enormous though unseen displacements, originating in the movements of atoms in molecules." REGENT GLACIAL WORK IN EUROPE. 103 RECENT GLACIAL WORK IN EUROPE. Bt Mrs. K. B. CLAYPOLE. AT the recent meeting of the British Association at Newcastle, Prof. James Geikie opened the Section of Geology with a summary of the results obtained during the last few years by continental glacialists. Sketching the steps by which the iceberg theory has been abandoned by German and Swiss geologists, he dwelt on certain features of the drifts of the peripheral areas, which for some time were hard to account for by land-ice. Of these, the bedded deposits occurring so frequently in the bowlder- clays of the peripheral regions, and the occasional silty and un- compressed character of the clays themselves, remained unex- plained until a clew was found to their origin in the geographical distribution of the clays in which they occur. ' These stony clays, of inconsiderable thickness in Norway, the higher parts of Sweden, and in Finland, reach a thickness of about forty-three metres in southern Sweden, and eighty metres in the northern parts of Prussia ; and in Holstein attain a depth of one hundred and twenty to one hundred and forty metres, and still greater depths in Hanover, Mark Brandenburg, and Saxony. The aqueous de- posits associated with the stony clays also gradually acquire more importance as they are followed from the mountainous and high- lying tracts to the low ground, until, along the southern margin of the drift area, the " diluvium " appears to consist of aqueous accumulations alone. The explanations of these facts by German geologists have been summed up recently (1884) by Dr. Jentzsch, from whom Prof. Geikie quoted enough to show that they are quite in accordance with the views long held by glacialists else- where. The general conclusions reached by continental glacialists, and summarized by Prof. Geikie, are : 1. Before the invasion of northern Germany by the inland ice, the low grounds bordering on the Baltic were overflowed by a sea which contained a boreal and arctic fauna. 2. The next geological horizon in ascending order is that which is marked by the glacial and fluvio-glacial detritus of the great ice-sheet which flowed to the foot of the Harz Mountains, and has been traced by the occasional presence of rock-strise and roches- moutonnees, of bowlder-clay and northern erratics, rather than by recognizable terminal moraines. 3. A well-marked temperate fauna and flora marks the inter- glacial beds which follow, and which, in their geographical dis- tribution and the presence in them of such forms as Elephas antiquus, Cervus elephas, and C. megaceros, and a flora compar- io 4 THE POPULAR SCIENCE MONTHLY. able to that now existing in northern Germany, justify geologists in concluding that this era was one of long duration, and charac- terized in Germany by climatic conditions apparently not less temperate than those that now obtain. 4. To this well-marked interglacial era succeeded a second overflow of Scandinavian inland ice, confined to a region much narrower than that covered by the first. Its boundaries are shown not only by the geographical distribution of the youngest bowlder- clay, but by the direction of rock-striae, the trend of erratics, and the position of well-marked moraines. Concerning the ground-moraines of the Alpine lands of cen- tral Europe, the only question that has recently given rise to much discussion is the origin of the materials themselves. The observations of able investigators appear to Prof. Geikie to have demonstrated that these materials have been derived, in chief measure, from the underlying rocks by the erosive action of the ice that overflowed them. German geologists are not agreed upon this much-debated question of glacier-erosion — a few still maintaining that glaciers have little or no eroding power. But where the evidences of erosion have been studied over a wide region, from which the ice has completely disappeared, rather than at the lower ends of existing glaciers, some of the strongest opponents of glacier-erosion have been compelled to go over to the other camp. As an example, Prof. Geikie quoted Dr. Blaas, who, through his observations on the glacial forma- tions of the Inn Valley, has recanted his former views and be- come a formidable opponent of the very theory which he once upheld. To his books and to memoirs by Penck, Bruckner, and Bohn, and especially to the chapter on glacier-erosion by the last- named author, Prof. Geikie refers those who may be anxious to know the last word on this question. Observations by Drs. Bruckner and Penck have led to the opinion that the loess is of interglacial age. Examining a wider range of evidence, Prof. Geikie has little doubt that the loess be- longs to no particular horizon, though it must be considered strictly a Pleistocene accumulation. Concerning its mode of formation he discussed the various theories advanced, and gave it as his opinion — an opinion formed from what he has himself seen of the loess in various parts of Germany, from reading, and from conversation with those who have worked over loess-covered re- gions — that it is for the most part of aqueous origin, formed in the slack waters of the great rivers, and in the innumerable tem- porary lakes which occupied or partly occupied many of the val- leys and depressions of the land. Probably some may have been derived from the denudation of bowlder-clay, some from " rain- wash/' while much of the so-called Bergloess with its abundant RECENT GLACIAL WORK IN EUROPE. 105 land-shells, and its generally unstratified character, owes its ori- gin to rain, frost, and wind. Admitting that some of the loess of the lower grounds may have been reworked by the same agents, Prof. Geikie fonnd no evidence in the facts adduced by German geologists of a " dry-as-dust " epoch having obtained in Europe during any stage of the Pleistocene period. Within recent years the fossils of the loess have received close attention, and through them so much knowledge has been gained of the various modifications experienced by Pleistocene organ- isms that, taken with other evidence of interglacial conditions, there is little room to doubt that this period was characterized by great changes of climate. How often arctic, steppe, prairie, and forest faunas and floras have replaced each other is yet a matter of dispute. The occurrence of fossiliferous deposits inter- calated among glacial accumulations throughout all the glaciated tracts of Europe show that however many advances and retreats of the ice there may have been, they were on a gigantic scale characterizing all the glaciated areas. The bearing of the establishment of at least two eras of glaci- ation on the position of Palaeolithic man was pointed out by Prof. Geikie. The mere occurrence of glacial deposits under- neath implement-bearing beds no longer proves these latter to be post-glacial. The horizon of glacial accumulations underlying Palaeolithic gravels must now be determined by ascertaining their relative position ; and it is a remarkable fact that the bowl- der-clays which occur beneath such old alluvia belong, without exception, to the earlier stages of the Glacial period. In 1871- , 72 Prof. Geikie published a series of papers in the Geological Maga- zine, maintaining that the alluvial and cave deposits must be assigned to preglacial and. interglacial times, and in chief to the latter. Evidence was adduced to show that during the last stage of the Glacial period man lived contemporaneously with a north- ern and Alpine fauna, in such regions as southern France ; and that Palaeolithic man and the southern mammalia never revisited northwestern Europe after extreme glacial conditions had disap- peared. Prof. Geikie at the same time colored a map to show at once the areas covered by the glacial and fluvio-glacial deposits of the last Glacial era, and the districts in which the implement- bearing and ossiferous alluvia had been found ; and this clearly brought out that the latter never occurred at the surface within the regions occupied by the former. Similar evidence has been recently obtained by continental geologists ; and a map published by Dr. Penck in 1884, showing the areas covered by the earlier and later glacial deposits in northern Europe and the Alpine lands, and indicating at the same time the various localities where Palaeolithic finds have occurred, does not give a single VOL. XXXVII. 8 io6 THE POPULAR SCIENCE MONTHLY. locality within the regions covered by the accumulations of the last Glacial era. So greatly are students of the Pleistocene ossif- erous beds influenced by what is known of the interglacial depos- its and their organic remains, that many do not now hesitate to correlate with those beds the old ossiferous and implement-bear- ing alluvia which lie altogether outside of glaciated regions. In France, where the relation of Pleistocene alluvia has been espe- cially canvassed, these alluvia have been also included among interglacial deposits. M. Boule also, in the Revue d'Anthropolo- gie, 1889, correlates the Palaeolithic cave and river deposits of France with those of other countries, and shows that they must be of interglacial age. He is satisfied that in France there is evidence of three glacial and two well-marked interglacial eras. The oldest of the Palaeolithic stages of Mortillet culminated during the last interglacial era, while the more recent Palaeolithic stages coincided with the last great development of glacier ice. The Palaeolithic age, so far as Europe is concerned, came to a close during this last cold phase of the Glacial period. Interesting as is the development of the climatic and geo- graphical changes of which our Palaeolithic predecessors were the witnesses, the clearing up of the history of Pleistocene times is not the only end that workers in this field have in view. Prof. Geikie, therefore, closed his address with a hope that the definite knowledge of the conditions of the Pleistocene period and of the causes which gave rise to them would lead to the better under- standing of the climatic conditions of still earlier ages ; the suc- cess with which other problems have been attacked by geologists forbidding him to doubt that ere long we shall have done much to dispel some of the mystery still enveloping the question of geo- logical climates. ■♦•» THE BOTANIC GARDENS AT KEW. By FKEDEK1K A. FERNALD. "T is now about two hundred years — the exact date is not -L known — since Lord Capel laid out the garden that has become a scientific institution of world-wide fame and influence. Switzer says, in his quaint Ichnographia Rustica, 1718, " The earliness with which this lord appeared in gardening merits a very great place in my history, and a better pen than mine to draw it." On the death of Lord Capel, in 1696, the estate of Kew House, includ- ing the garden, passed into the hands of his son-in-law, who added to its importance for a while by making it the headquarters of English astronomy. It was afterward leased by Frederick, Prince of Wales, son of George II. The garden was made a scientific es- THE BOTANIC GARDENS AT KEW. 107 tablishment— what they called a " Physic Garden" in those days— by the widow of Frederick, the dowager Princess Augusta, under the advice of the Earl of Bute. She employed William Aiton to direct the scientific work, and Sir William Chambers to superin- tend the decorative gardening. " Science will ever be grateful to the one," says a writer in The Saturday Review,* "and Taste will never forgive the other while his constructions remain." In 1768 Sir John Hill published a catalogue of the plants at Kew. There were fifty ferns, about six hundred trees and shrubs, and several thousands of herbaceous plants. The list was not greatly lengthened twenty-one years after, when Aiton issued the Hortus Kewensis with the aid of Dr. Solander. But the collections made by Sir Joseph Banks in Captain Cook's famous voyage were deposited here ; then those of Robert Brown and Allan Cunning- ham, who had accompanied Captains Flinders and King respect- ively to Australia; then the plants of Brazil and the Cape of Good Hope, gathered by Messrs. Bowie and Masson; those of Caley, and Ker, and Menzies, and a host of smaller collections. In 1810 William Aiton the younger published a new edition of his father's work, which contained nearly ten thousand descrip- tions. About 1789 the estate was bought by George III, who devoted much of his leisure to its improvement. But evil days followed the death of Sir Joseph Banks, in whom Kew had a friend at court. For all Aiton could do, the gardens sank into neglect, and in 1838 it was proposed to disestablish and disendow them. A protest was raised, and, after further consideration, the gardens were surrendered by the crown and became a national establish- ment in 1810. Sir W. J. Hooker was appointed director in the following year. Kew has been fortunate in having had few changes in directors. It was in charge of William Aiton from 1759 to 1793 ; of William Aiton, Jr., from 1793 to 1840 ; Sir W. J. Hooker was director from 1841 to 1866 ; his son, Sir Joseph D. Hooker, from 1866 to 1886 ; and to him has succeeded Mr. W. T. Thiselton Dyer. Under the directorship of Sir W. J. Hooker the Royal Botanic Gardens rapidly advanced in importance. During his term of ofiice a report of the Progress and Condition of the gardens was made annually. This was superseded in 1883 by a monthly Bul- letin of Miscellaneous Information. The early reports of Sir William Hooker are interesting, besides their historic and scien- tific value, for the evidence they give of his sturdy, ceaseless bat- tles with the Treasury. The director is pathetic, indignant, and argumentative by turns, and one way or another he contrived to * The writer is indebted to an appreciative article in The Saturday Review (Lon- don), of October 5, 12, and 19, 1889, for the material of this sketch. io8 THE POPULAR SCIENCE MONTHLY. worry on till better times. In 1844 Sir William took the first important step of his administration by petitioning for a grant of the Royal Fruit House, which he offered to fill with his private collection of plant products. It was allowed in 1847, and thus the Museum of Economic Botany had its origin. This branch of the establishment now occupies three buildings. Every tree and plant which is known to serve a useful purpose is represented there, with illustrations of the manner of its employment, if pos- sible. While the collection is very popular with the holiday vis- itor who comes only to be entertained, any one can understand its serious value to an ingenious and thoughtful mechanic or manu- facturer. The Museum of Timber is largely used already. Cabi- net-makers and furniture manufacturers quite recognize by this time what a store of hints for their craft is garnered here. The utility of the economic section, moreover, is by no means confined to the inhabitants of the British Isles. From every quarter of the globe samples of new products are sent for examination and report. So long ago as 1815 an Herbarium and Botanical Library had been projected at Kew. George III, doubtless persuaded by Sir Joseph Banks, even raised a building for the purpose. After Sir Joseph's death, however, the scheme lapsed, and the building was granted to the King of Hanover. On his decease, Sir William Hooker urged the fulfillment of the old design, and his petition was granted when Mr. Bentham and Dr. Bromfield bequeathed their collections to the nation. The Herbarium of Kew is the largest in the world, and by far the most useful, because it is also most admirably arranged. The number of specimens in it is not on record. At Sir William Hooker's death, twenty-four years ago a rough estimate made the number a million, exclusive of dupli- cates. The written catalogue fills two gigantic volumes, and has to be continually posted up, for the collection increases by twenty thousand or so yearly. The dried plants in their portfolios stand in cases, and all are arranged upon the system of Sir Joseph Hooker's great work, the Genera Plantarum. The student has only to give the number attached to any genus in that book, and the case is unlocked and the portfolio laid before him in a mo- ment. There are no formalities to check the young scholar here. He has but to present his credentials to Prof. Oliver, keeper of the herbarium, sign his name, and get to work. There are inter- esting features at every step of this noble collection, fascinating bits of history connected with every group of cases which bears the name of some distinguished botanist, the fruits of whose life- long labor are stored here. Of all these, perhaps the herbarium of Dr. Lindley is the most attractive. It occupies only four small cabinets, but the contents will surpass the visitor's utmost expec- tations. On the lower floor is preparing the catalogue of all plants THE BOTANIC GARDENS AT KEW, 109 known, for which Mr. Darwin left a bequest. Mr. Daydon Jack- son, Secretary to the Linnsean Society, has had the work in hand over three years, and it is not nearly finished. He employs a staff at the British Museum also, The catalogue of the library is not printed, but is contained in a ponderous manuscript volume in the keeper's room. The books include, besides all modern volumes and pamphlets on botany, a great number of those antique curios- ities which bibliomaniacs treasure. The work at Kew covers a vast field. In the first place officially stand the botanic interests — to study new plants and class them. Next, where plants are wanted for cultivation, which can not be obtained readily in the market, or which the service of the public demands, the Royal Gardens will supply them if possible. Where diseases, vegetable or animal or insect pests, threaten local plan- tations, Kew will look into the matter and consult with experts at home. Kew is ready also to report and to obtain advice upon new-industries which those upon the spot suggest. Furthermore, it keeps an eye on all institutions of the same class through- out the British Empire, which act in concert with their great model in the mother-country, and through it with one another. Foreign institutions co-operate in like manner with Kew to a cer- tain extent. From time to time the authorities of Kew publish a list of new plants, which at present seem to average five hundred to six hundred a quarter, including those renamed for scientific purposes. From time to time, also, they publish a list of the seeds matured in the Royal Gardens, which are exchanged, on appli- cation, with all regular correspondents. One of these seed-lists includes something like four thousand species. This magazine of seeds is collected, nominally, for the benefit of institutions which may be able some time to return the favor in part, but in practice no one who applies with a serious purpose for seeds or plants is refused. How the rapidly increasing population of the globe is to be provided with food and clothing is a problem which the au- thorities of Kew believe falls within their department. They wel- come every vegetable product which is reported to have qualities that make it useful to mankind, whether as a food, a medicine, a convenience, or a substance useful in manufactures. They are glad to report upon specimens of such substances, or to obtain the reports of trustworthy experts. The story of the cinchona plantations is a good instance of the work of the Royal Gardens. Some forty years ago both the Eng- lish and the Dutch authorities in the East Indies took alarm at the growing price of quinine, due to the rapid decrease of the for- ests of cinchona in Peru. The Dutch moved first, and imported a great number of seeds and seedlings, which they planted in Java at a heavy cost. But, probably because they had no Kew to advise no THE POPULAR SCIENCE MONTHLY, them, the Dutch had chosen a species which was hardly worth growing, and the plantations have been long since nprooted. For some years the English Government confined itself to importing seeds and plants, which died on the passage to India. This was evidently futile, and Sir William Hooker urged a systematic pro- cedure. Mr. Clements Markham, in 1859, was sent to Peru to col- lect seeds and young trees. When he returned, his precious stores were received at the Gardens, nursed, and transmitted to India with trifling loss. This effort was successful. In the plantations of Bengal, laid out and managed by officers recommended by Sir William Hooker, there were, at the date of the latest report, about five million trees. From Kew cinchona-trees have been distrib- uted also to all parts of the world where there was a chance for successful cultivation. The plantations of Ceylon are only infe- rior to those of Bengal ; in Jamaica the sales of bark exceed £5,000 a year ; the tree has been introduced also into St. Helena, Trinidad, Mauritius, Cape of Good Hope, Queensland, and many other settlements. The output of the cinchona drugs from these sources up to 1880 was 87,704 pounds, which, taking quinine at an average value of two dollars an ounce, would represent $2,806,528. Ipecacuanha is a plant scarcely less important than cinchona itself. But few members of the vegetable kingdom so absolutely refuse to exist under anything short of perfectly satisfactory con- ditions. In 1866 Sir Joseph Hooker sent a specimen to the Bo- tanical Gardens at Calcutta, which promptly died. Then a strug- gle began in which the advantage was now on one side, then on the other. In 1875 the Director of the Calcutta Gardens tri- umphantly reported that he had one hundred thousand nice young plants, but in 1886 the strain received from Kew direct alone sur- vived — less than five per cent — and all hope of successful cultiva- tion in India has been abandoned long since. Plants had been sent out to Singapore, however, in 1875, # with much more lively confidence, and there perseverance found its reward. Ipecacuanha is established in the Old World at last, and the authorities of Kew may be trusted to diffuse the cultivation. Another instance is Liberian coffee, distributed from Kew to take the place of that grown in the East Indies, which was affected by a fungoid pest, and that of the West Indies, which suffered from the white fly. Liberian coffee, moreover, will thrive in hot and moist situations, where the Arabian variety is unable even to live. It has been introduced in a great many places, but, although its growth is very promising, it has nowhere become the general crop. This imperfect success was another problem for the investigators of Kew, and the solution is now believed to be found in the fact that the treatment proper for the Arabian berry after gathering is not suited to the Liberian, with a widely different pulp. THE BOTANIC GARDENS AT KEW. m Among the many questions sent to Kew from all parts of the world, there must "be some of trivial importance, or which could be perfectly well answered at the local* botanic gardens. But all genuine inquiries receive attention. Debate has been gravely held, opinions even have been formed and reported upon such matters as a South African cane which some gentleman in those distant parts thought adapted for fishing-rods ; upon the value of West African palm-kernels as material for coat-buttons ; upon a pithy stem which the government of a West India island believed suitable for razor-strops. One function of a national institution very seriously regarded at Kew is the training of young men to fill botanic situations in the colonies. Something is demanded of such young men beyond the practical knowledge which suffices at home. Instruction is given them in the principles of scientific botany, and those general conditions which rule the practice of horticulture under differing circumstances. The advantage of this system all around scarcely needs illustration. While serving the interest of the colonies, it increases the sources of information for Kew, since all these emi- grants keep up more or less of a correspondence with the institu- tion in which they were trained. The village of Kew lies on the south side of the Thames, about six miles westward from Hyde Park Corner in London. " The Gardens " are a favorite resort for holiday-makers and tourists, being visited by six or seven hundred thousand persons yearly. Painters also flock there in summer-time. When the crown sur- rendered its rights to them in 1840, the Gardens had an area of eleven acres, and contained ten greenhouses of one sort or another. Sir William Hooker promptly begged permission to annex the Orangery and the land adjacent ; then a part of the Pleasure Grounds ; and after that the Royal Kitchen and For- cing Grounds. All these petitions being granted, by 1847 the Gardens had reached their present dimensions — about seventy acres. Three years later the rest of the Pleasure Grounds was granted for the establishment of an Arboretum, making the total area little less than two hundred and fifty acres. " The Arbore- tum is the richest in Europe, no doubt," says the writer in The Saturday Review, "but probably inferior to that of Harvard University, where special attention has been paid to this depart- ment." This admission in a British journal, and The Saturday Review above all others, should be very gratifying to Ameri- cans. The failure of Kew's Arboretum to be the finest in the world is explained on the ground that the soil — sandy and shal- low, resting on a stratum of gravel — is unsuited to many kinds of trees. In former times, also, when an imperial collection had to be got together as quickly as possible, and as cheaply, specimens 112 THE POPULAR SCIENCE MONTHLY. were not planted with the care which might have overcome the disadvantage. It became necessary to reconstruct the Arboretum twenty years ago on this account. A singular example of the in- fluence of fashion in gardening then came to light. The British public had been running after evergreens so hotly that nursery- men had ceased to grow deciduous species. It seems incredible that the authorities of Kew should have asked in vain for months throughout England, Scotland, and Ireland, for young aspens. As for American oaks, maples, etc., they absolutely could not be found in the kingdom. Unscientific lovers of the beautiful may rejoice that it has not yet been found necessary to interfere with the old forest trees, planted, perhaps, by Lord Capel. The new-comers are arranged by genus — all the willows, for example, with the alders, around the pretty lake, pines here, cedars there, oaks, nuts, maples, tamarisks, camellias, ranunculus, etc., etc. In the Garden proper the smaller plants are found in bewilder- ing array. No list of the species represented at Kew has been taken since that of the younger Aiton in 1810, but one is now being made. Some departments have been catalogued already. Of orchids, there are about 1,400 species ; ferns, 1,100 ; stove plants, 2,500 ; succulents, 1,000 ; palms and cycads, 500 ; greenhouse plants, 3,000 ; herbaceous, 4,000 ; trees and shrubs, 3,000 ; in several cases, however, the figure is but a guess as yet. The total, great as it will prove to be, bears but a small proportion to the sum of Na- ture's wealth. If we take the flowering plants alone, as enumer- ated in Bentham and Hooker's Genera Plantarum, there are two hundred natural orders, 10,000 genera, and 100,000 species; and this leaves out of account the ferns and all the lower orders of Cryptogamia. The Economic Section has few visitors, and they are not tempted to carry exploration far. Not a few of the culi- nary and medicinal herbs in use are found here. If by some fatal chance the onion of commerce should be exterminated in the back-gardens of England, Kew is prepared to replace it. Side by side therewith grow the patience-dock and the skunk-cabbage, the briony, the cuckoo-pint, the Japanese yam, and the all-good. In ferns the Kew collection is exceedingly rich. It has had three special benefactors in this department, to the first of whom, Mr. George C. Joad, the public is indebted for the charming rock-gar- den opened in 1881. Sir Joseph Hooker had long been working for one, and the bequest of Mr. Joad's collection of ferns brought the matter to a crisis. Dr. Cooper Forster was an enthusiast upon the culture of filmy ferns, and Mr. W. C. Carbonell was specially interested in the cultivation of hardy ferns, particularly in the crossing of them, and the development of sports. Both these gen- tlemen bequeathed their treasures for the nation's enjoyment when their own power of enjoying them ended. SKETCH OF HENRY R. SCHOOLCRAFT. 113 The glass houses at Kew are extensive structures. The Win- ter Garden covers more than an acre and a half of ground. The Palm House is three hundred and sixty-two feet long and one hun- dred feet wide. The new Orchid House is one hundred and forty feet in length, adding the two wings together. This last is not wholly satisfactory — to the orchid enthusiast an orchid house never is, nor can be. Supplemented, however, by a low, neat range, from which the public is excluded, nearly all the 1,400 spe- cies which form the national collection thrive admirably. British orchidists are proud of Kew — nowadays — for it was not so satis- factory in this department a few years since. +•» SKETCH OF HENRY R. SCHOOLCRAFT. MR. SCHOOLCRAFT was a conspicuous figure in the scien- tific life of the early part of the century. A pioneer in some fields, the immediate follower of the pioneers in others, he was, in all the branches of research to which, he gave atten- tion, earnest, ready, diligent, sagacious, original, and modest. As among his titles to be remembered, the biographer who prefaces his Personal Memoirs names the early period at which he entered the field of observation in the United States as a naturalist ; the enterprise he manifested in exploring the geography and geology of the Great West ; and his subsequent researches as an ethnolo- gist in investigating the Indian languages and history. " To him we are indebted for our first accounts of the geological constitu- tion and the mineral wealth and resources of the great valley beyond the Alleghanies, and he is the discoverer of the actual source of the Mississippi River in Itasca Lake. For many years, beginning with 1817, he stirred up a zeal for natural history from one end of the land to the other, and, after his settlement in the West, he was a point of approach for correspondents " — on these topics and for all the Indian tribes. Henry Rowe Schoolcraft was born in Albany County, K Y., March 28, 1793, and died in Washington, D. C, December 10, 1864. He was the descendant, in the third generation, of an English- man, James Calcraft, who, having served with credit in the armies of the Duke of Marlborough, came to America in the reign of George II, in the military service, and was present at operations connected with the building of Forts Anne, Edward, and William Henry. After these campaigns he settled in Albany County as a land-surveyor, married, and in his old age conducted a large school — the first English school that was taught in that frontier region. In connection with this incident his name became TOL. XXXYII. — 9 ii 4 THE POPULAR SCIENCE MONTHLY. changed to Schoolcraft. He died at the age of one hundred and two years. John, his third son, was a soldier under Sir William Johnson. Lawrence, John's son, distinguished himself during the siege of Fort Stanwix. He was afterward director of the glass- works of the Hon. Jeremiah Van Rensselaer, at Hamilton, near Albany ; and established the manufacture of glass in western New York. Henry Schoolcraft spent his childhood and youth in Hamilton, cultivated poetry, and maintained an excellent standing in schol- arship. At an early age he manifested a taste for mineralogy and natural science, which were then (about 1808) almost un- known in the country ; formed the beginnings of collections ; and organized an association for mental improvement. He inves- tigated the drift stratum of Albany County as seen in the bed of Norman's Kill ; and afterward, while living at Lake Dunmore, Vt., put himself under the teaching of Prof. Hall, of Middlebury College; added chemistry, natural philosophy, and medicine to his studies ; erected a chemical furnace, and went into experi- menting ; and picked up a knowledge of Hebrew, German, and French. He began writing for books and periodicals in 1808 — contributing, among other things, papers on the Burning Springs of western New York, and on archaeological discoveries that had been made in Hamburg, Erie County. In the last paper, which was published at Utica in 1817, he pointed out the necessity of discriminating between the antique French and European, and the aboriginal period, in American antiquity. He was engaged for a time in directing the building of works connected with his father's glass-making enterprises in Vermont, New Hampshire, and western New York. The ideas and knowledge gained in these operations supplied the material for his proposed work on Vitreology, or the application of chemistry to glass-making, the publication of which was begun in 1817. The supervision of these works required the making of considerable journeys, and these created in him the desire to travel through the wilds of the " Far West," which then hardly extended beyond the Missouri River. He made some " preliminary explorations " to his contemplated journey in western New York in 1816 and 1817, and started from Olean on the Alleghany River for a journey down the Ohio and up the Mississippi in 1818. A large company of intending emi- grants had gathered there waiting for the season to open, and Schoolcraft took passage in the first ark. Arrived at Pittsburg, he stopped to explore the geology of the Monongahela Valley, and was greatly interested in the rich coal and iron beds. He stopped to visit the Grave Creek mound and the ancient works at Mari- etta. At Louisville he found " organic remains " of several spe- SKETCH OF HENRY R. SCHOOLCRAFT. 115 cies in the limestone rocks of the falls, and published anony- mously in the paper some notices of its mineralogy. At the month of the Cumberland River he exchanged the ark for a keel- boat or barge, with which, propelled by poles pushing on the bot- tom, he made from three to ten miles a day against the swift cur- rent of the Mississippi to Herculaneum, Mo. On this voyage he traveled over a large part of the west bank on foot, and gleaned several facts in its mineralogy and geology which made it an initial point in his future observations. He spent three months in examining the lead mines, personally visiting every mine or digging of consequence in the Missouri country and tracing its geological relations into Arkansas. Hearing of syenite suitable for millstones on the St. Francis, he visited that stream and dis- covered the primitive tract ; and he pushed his examinations west beyond the line of settlement into the Ozark Mountains. He now determined to call the attention of the Government to the impor- tance of its taking care of its domain in the mines, and with this purpose packed his collections and took passage in the new steamer St. Louis for New Orleans. Hence, having inquired into the formation of the delta of the Mississippi, he sailed by brig for New York. He opened his collections and invited examination of them, published a book on the mines and physical geography of the West and a letter on its resources, and went to Washing- ton to present his views on the care of the mines to the officers of the Government. While he was looking for a secretary within whose purview the matter fell, Mr. Calhoun invited him to ac- company General Cass, Governor of Michigan, as naturalist and mineralogist on an expedition to explore the sources of the Mis- sissippi and to inquire into the supposed value of the Lake Supe- rior copper mines. He accepted the position, though the compen- sation was small, because, he says, " it seemed to be the bottom step of a ladder which I ought to climb." Mr. Schoolcraft left New York in March, 1820, reached Niag- ara Falls on the 1st of May, and Detroit by steamer a week later. While waiting for the completion of arrangements for embar- kation, he attended to the correspondence which had been pro- voked by the publication of his work on the mines and the re- sultant awakening of interest in the varied resources of the Mississippi Valley and the subject of geographical and geological explorations. He determined to reply to all letters that appeared to be honest inquiries for geographical facts, " which I only, and not books, could communicate." The route of the expedition " lay up the Detroit and St. Clair Rivers and around the southern shores of Lakes Huron and Superior to Fond du Lac, thence up the St. Louis River in its rugged passage through the Cabotian Mountains to the Savannah summit which divides the Great Lakes n6 THE POPULAR SCIENCE MONTHLY. from the Mississippi Valley. The latter was entered through the Cantaguma or Sandy Lake River. From this point the source of the Mississippi was sought up rapids and falls and through lakes and savannahs, in which the channel winds. We passed the inlet of Leech Lake, which was fixed upon by Lieutenant Pike as its probable source, and traced it through Little Lake Winnipeg to the inlet of Turtle Lake in upper Red Cedar or Cass Lake in lati- tude 47°. On reaching this point the waters were found unfavor- able to proceeding higher. The river was then descended to the falls of St. Anthony, St. Peter's, and Prairie du Chien. From the latter point we ascended the Wisconsin to the portage into Fox River, and descended the latter to Green Bay." At this point the expedition was divided. The party to which Mr. Schoolcraft was attached proceeded to Chicago, thence traced the eastern coast of Michigan, and rejoined the other party, which had gone north to trace the shores to Michilimackinack. About four thou- sand miles were traversed. Reports were made to the Govern- ment by Mr. Schoolcraft on the mineralogy and geology of the region ; on the copper deposits of Lake Superior ; on the botany, fresh-water conchology, zoology, and ichthyology; soil, produc- tions, and climate received attention ; and the Indian tribes were subjects of observation by General Cass. " In short, no explora- tion had before been made which so completely revealed the feat- ures and physical geography of so large a portion of the public domain." A new interest in mineralogy and geology was awak- ened by this expedition, and Mr. Schoolcraft's narrative of it was hurried into press under the pressure of the public clamor for its results. The book was published in May, 1821. Mr. Schoolcraft shortly afterward embarked, with General Cass, on another expedition. The route lay. from the present site of Toledo, up the Miami of the lakes, down the Wabash and Ohio to Shawneetown, overland across the " knobs " and prairies, taking a famous locality of fluor-spar on the way, to St. Louis ; thence up the Illinois to the rapids and on horseback to Chicago, stopping to find the fossil tree in the bed of the Des Plaines. In Chicago, a treaty was made with the Pottawattamies for the surrender of about five million acres of land, to which Mr. Schoolcraft should have given his signature among the others, but he was too ill — { did not, indeed, ever expect to make another entry in a human journal." The incidents and observations of the journey have been published as Travels in the Central Portions of the Missis- sippi Valley. In the next year (1822) Mr. Schoolcraft was ap- pointed Indian agent at Sault Ste. Marie, of which he says, giving his reasons for accepting it : "I had now attained a fixed posi- tion ; not such as I desired in the outset and had striven for, but one that offered an interesting class of duties, in the performance SKETCH OF HENRY R. SCHOOLCRAFT. 117 of which, there was a wide field for honorable exertion, and, if it was embraced, also of historical inquiry and research. The taste for natural history might certainly be transferred to that point, where the opportunity for discovery was the greatest." The posi- tion afforded him excellent opportunities for studying the Chip- pewa language and Indian mythology and superstition, character- istics, and customs, of which he made the best use. He deter- mined to be a laborer in the new field of Indian studies. His diary during the whole term of his office shows him leading a busy and varied life. We find in it notes on his subjects of study, of his readings on various general topics, observations on the natural features of the region, remarks on mineralogical specimens, and incidents of official work. Mr. Schoolcraft spent the winter of 1824- J 25, on leave of ab- sence, in New York, where he superintended the printing of his Travels in the Central Portions of the Mississippi Valley. " So- ciety " was much interested in Mrs. Schoolcraft, the Northern Pocahontas," a lady of aristocratic Irish descent on one side, and tracing her ancestors on the other side to the royal house of the Chippewas, who was withal, having been educated abroad, highly accomplished and refined in her manners. She was the daughter of Mr. John Johnston, of Sault Ste. Marie, who had married the daughter of Wabojeeg, a distinguished Chippewa chieftain. In 1825 he attended a convocation of the Indian tribes at Prairie du Chien, where a treaty was signed, through which it was hoped internal disputes between the tribes might be settled by fixing the boundaries to their respective territories. In the next year he at- tended a similar gathering of the Chippewa tribes at Fond du Lac, where the principles of the treaty of Prairie du Chien were reaf- firmed, and a new treaty was made, under which the Indians ac- knowledged the sovereign authority of the United States ; ceded the right to explore and take away the native copper and copper ores, and to work the mines and minerals in the country ; and provision was made for the education of the Indians and their advancement in the arts. The system of Indian boundaries established by these treaties was completed by the treaty of Butte des Morts, August, 1827. The three treaties embodied a new course and policy for keeping the tribes in peace, and were founded " on the most en- larged consideration of the aboriginal right of fee simple to the soil." In 1827 he was elected a member of the Legislative Council of the newly organized Territory of Michigan — an office which was not solicited, and was not declined. As a member of this body during four sessions, he directed his attention to the incorporation of a historical society ; to the preparation of a system of township names derived from the aboriginal languages ; and to some efforts for bettering the condition of the natives. n8 THE POPULAR SCIENCE MONTHLY. A proposition was made to Mr. Schoolcraft in 1828 to go as one of the scientific corps of an exploring expedition which the Government contemplated sending to the south seas, under the direction of the Secretary of the Navy. In his reflections on the prospects of this expedition and the acquisitions to knowledge that might be expected to accrue from it, he regarded the experi- ments of Dr. Maskelyn, denoting a greater specific gravity in the central portion of the globe than in its crust, as opposed to a theory that was then advocated of an interior void. Yet he thought " we are advertised, by the phenomena of earthquakes, that this interior abounds with oxygen, hydrogen gas, caloric, and sulphur, and that extraordinary geological changes are af- fected by their action. It does seem improbable that the pro- posed expedition will trace any open connection with such an interior world ; but it may accumulate facts of the highest impor- tance." There was something, however, about the getting up and organization of the expedition which he did not like, and an apprehension whether Congress would not cripple it by voting meager supplies and outfits. He declined to go. A note from Mr. G. W. Featherstonaugh, giving a disparaging view of American scientific achievement, and inclosing the pro- spectus of a journal designed to correct these things, gave Mr. Schoolcraft opportunity for bearing strong tribute to the genu- ineness of real American scientific research. The critic's remarks might be true as to a certain class, who had not made science a study; but, if applied to the power and determination of the American mind devoted to natural history, it was " not only un- just in a high degree, but an evidence of an overweening self- complaisance, imprecision of thought, or arrogance. No trait of the American scientific character has been more uniformly and highly approbated by the foreign journals of England, France, and Germany than its capacity to accumulate, discriminate, and describe facts. For fourteen years past, Silliman's Journal of Science, though not exclusively devoted to natural sciences, has kept both the scientific and the popular intelligent mind of the public well and accurately advised of the state of natural science the world over. Before it, Bruce's Mineralogical Journal, though continued but for a few years, was eminently scientific; and Cleaveland's Mineralogy has had the effect to diffuse scientific knowledge not only among men of science, but other classes of readers. In ornithology, in conchology, and especially in botany, geology, and mineralogy, American mind has proved itself emi- nently fitted for the highest tasks." The Michigan Historical Society was founded, chiefly through Mr. Schoolcraft's instrumentality, in 1828, and the Algic Society on February 28, 1832. The latter organization had in view the SKETCH OF HENRY R. SCHOOLCRAFT. 119 reclamation of the Indians, and, connected with, this, the collec- tion and dissemination of information respecting their language, history, traditions, customs, and character; their numbers and condition ; the geological features of their country, and its natural history and productions. It also proposed some definite means of action for furthering the moral instruction of the Indians, and for helping the missionaries in all work for their benefit. As president of this society, Mr. Schoolcraft was asked to lecture on the grammatical construction of the Algonquin languages as spoken by the Northwestern tribes, and to procure a lexicon of it ; also to deliver a poem on the Indian character at the annual meeting of 1833. Other literary efforts of this period were, an address before the Historical Society of Michigan in 1830, and an address, in 1831, before the Detroit Lyceum, on the natural history of the Territory. In the summer of 1832 Mr. Schoolcraft, under a commission from the Government, organized and commanded an expedition to the country upon the sources of the Mississippi River. The primary object of the expedition was to extend to the Indians living north of St. Anthony's Falls the measures previous- ly taken with those south of that point, to effect a pacification ; also, to endeavor to ascertain the actual source of the river. He ascend- ed the St. Louis from Lake Superior to Sandy Lake summit, and passed thence direct to the Mississippi six degrees below the central island in Cass Lake, which was till then the ultimate point of geo- graphical discovery. Thence he went up the river and its lakes, avoiding too long circuits of the stream by portages, to the junc- tion of the two branches, where by the advice of his Indian guide he took the left-hand, or Plantagenian branch, to Lake Assawa, its source. Thence he went by portage, a distance of " twelve rest- ing-places," to Itasca Lake, which he struck within a mile of its southern extremity. The lake was judged to be about seven miles in length, by one or two broad ; " a bay, near its eastern end, gave it somewhat the shape of the letter y." The discoverer returned, through the stream and its lakes,, to St. Peter's. The narrative of this expedition was published in 1834 ; and was republished, with the account of the expedition of 1820, in 1853, under the title, Narrative of an Exploratory Expedition to the Sources of the Mississippi River in 1820, completed by the Discovery of its Origin in Itasca Lake in 1832. The whole of Mr. Schoolcraft's earlier life and work up to this time is recorded, mostly from day to day, in his Personal Memoirs of a Residence of Thirty Years with the Indian Tribes on the American Front- iers, etc., 1812 to 1842, a book having " the flavor of the time, with its motley incident on the frontier, with Indian chiefs, trappers, government employe's, chance travelers, rising legislators, farmers, ministers of the gospel, all standing out with more or less of indi- 120 THE POPULAR SCIENCE MONTHLY. viduality in the formative period of the country." This book abounds with evidence of Mr. Schoolcraft's scientific and literary activity, as well as of his efficiency in work in whatever field. As early as 1820 we find a letter from Amos Eaton, asking him for information for the second edition of his Index to Geology, respecting the secondary and alluvial formations and the strata of the Rocky Mountains. Dr. Samuel Mitchell writes him, in 1821, about the shells and other specimens he has sent, including a " sandy fungus," and inviting specimens for the cabinet of the Emperor of Austria. Profs. Silliman and Hall acknowledge the value of his examination of the mining regions of Missouri ; Prof. Silliman asks for articles for his journal ; and Sir Humphry Davy thinks his book would sell well in England. Prof. Cleaveland writes him, in 1827, that he is about preparing a new edition of his work on mineralogy, and solicits the communication of new localities. In the same year Mr. Schoolcraft himself writes that the collection he made in Missouri, etc., in 1819, appears to have had an effect on the prevalent taste for those subjects, " and at least it has fixed the eyes of naturalists on my position on the frontiers." Mr. Peter S. Duponceau addresses him, in 1834, on the structure of the Indian languages, " in terms which are very complimentary, coming, as they do, as a voluntary tribute from a person whom I never saw, and who has taken the lead in investi- gations on this abstruse topic in America." He pronounces Mr. Schoolcraft's book on the Chippewa languages one of the most philosophical works on the Indian languages which he has ever read. In another letter Mr. Duponceau acknowledges having used Mr. Schoolcraft's grammar, giving due credit, in preparing a prize essay for the Institute of France, on the grammatical struct- ure of Indian languages. Dr. Thomas H. Webb, of Providence, in 1835, notifies him of his election as an honorary member of the Rhode Island Historical Society, and asks about aboriginal in- scriptions on rocks. The Massachusetts Historical Society, in 1836, asks him to proceed with his work on the Ojibway lan- guage, complete it, and let the society publish it. John J. Audu- bon asks for aid in preparing his work on American quadrupeds. There are numerous notices of specimens that have been sent to Mr. Schoolcraft to pass upon, and solicitations from persons rep- resenting the principal magazines, to contribute of the results of his researches. A new disposition of official posts having been made, Mr. Schoolcraft transferred his residence in 1837 to Michilimackinac or Mackinaw. Thence he removed, in 1841, to New York, where he expected to find the surroundings more favorable to the col- lation and publication of the results of his observations on the red race, whom he " had found in many traits a subject of deep SKETCH OF HENRY R. SCHOOLCRAFT. 121 interest ; in some things wholly misunderstood and misrepresent- ed ; and altogether an object of the highest humanitarian inter- est." But the publishers were not yet prepared in their views to undertake anything corresponding to his ideas. In the next year he carried out a long-deferred purpose of visiting England and continental Europe, attending the British Association at Man- chester. On his return he made a tour through western Vir- ginia, Ohio, and Canada. In 1875 he was appointed by the Legis- lature of New York as a commissioner to take the census of the Indians of the State, and collect information concerning the Six Nations. The results of this investigation were embodied in his Notes on the Iroquois, a second enlarged edition of which was published in 1847. The latter part of his life was spent in the preparation — under an act passed by Congress in 1847 — of an elaborate work on all the Indian tribes of the country, based upon information obtained through the reports of the Indian Bureau. This work — which was published in six quarto volumes — is de- scribed in Duyckink's Cyclopaedia of American Literature as cov- ering a wide range of subjects in the general history of the race ; their traditions and associations with the whites ; their special antiquities in the several departments of archaeology in relation to the arts ; their government, manners, and customs ; their phys- iological and ethnological peculiarities as individuals and na- tions ; their intellectual and moral cultivation ; their statistics of population ; and their geographical position, past and present. Mr. Schoolcraft became interested in religion at an early pe- riod in his career, and his journals show him ever more earnestly co-operating in local religious movements ; furthering the prog- ress of missionary effort among the Indians, by whatever de- nomination ; laboring for the promotion of temperance among them ; and taking the lead in whatever might contribute to their well-being or to the repression of wrong against them. His literary activity was prolific, and appears to have .been nearly evenly divided between poetry, Indian lore and ethnology, and the objects of his explorations and scientific investigation. Be- sides books of poems and the narratives already named, he pub- lished Algic Researches, a collection of Indian allegories and legends (1839) ; Oneota, or the Characteristics of the Red Race in America (1844-'45), republished in 1848 as The Indian and his Wigwam; Report on Aboriginal Names and the Geographical Terminology of New York (1845) ; Plan for investigating Ameri- can Ethnology (1846) ; The Red Race of America (1847) ; A Bib- liography of the Indian Tongues of the United States (1849) ; and American Indians, their History, Condition, and Prospects (1850). He received the degree of LL. D. from the University of Geneva in 1846 ; and was a member of many learned societies. 122 THE POPULAR SCIENCE MONTHLY. CORRESPONDENCE. AGRICULTURE 02T THE PLAINS. Editor Popular Science Monthly : IN the February number of The Popular Science Monthly was published an arti- cle, by Stuart 0. Henry, entitled Rainfall on the Plains. Mr. Henry claims that the rainfall on our plains has not increased to any appreciable extent since the first settle- ment ; and he says that the general impres- sion that settlement and cultivation traveling westward have been attended by a gradual increase of rainfalls is a " remarkable falla- cy." He concludes that agricultural opera- tions can never be successfully carried on west of a line about the ninety-eighth me- ridian, and that attempts to utilize the regions named for purely agricultural purposes, with- out artificial irrigation, will only result in calamitous failure. Mr. Henry makes the statement that " the reports of the Kansas and Nebraska Boards of Agriculture will show that, in the territory lying west of the ninety-eighth meridian in those States, the acreage of land actually under cultivation, when compared with the whole area of that territory, is almost insignificant." After seventeen years of residence in southwestern Nebraska, near the one hundredth meridian, I am convinced that Mr. Henry is correct as to the absence of an increase of rainfall ; but his conclusions are very erroneous, and must have been formed without informa- tion as to the great growth in wealth and population in the region west of the ninety- eighth meridian during the last ten years. The statement that the cultivated land west of the ninety-eighth meridian in Kansas and Nebraska is insignificant when compared with the whole area of that territory may have been true ten years ago, but at the present time it is far from the truth. The writer believes that no increase of rainfall has ever been necessary to fit the country named for profitable farming, but that the rainfall has always been sufficient, and that the obstacles to farming that have existed resulted from the newness of the country, rather than from lack of rain, and that these obstacles are gradually disappearing as the country settles up, and will wholly disappear when the coun- try becomes as densely settled as are the States of Iowa and Illinois. Mr. Henry's gloomy statements seem like an echo of predictions made by sundry scien- tific gentlemen twenty years ago concerning the plains of Kansas and Nebraska ; and he might be aptly compared to a modern Rip Van Winkle, who has just awakened after a twenty years' sleep, ignorant of the wonderful growth that the country west of the ninety- eighth meridian has made. When he penned the lines quoted, was he aware that Jewell County, Kansas, which lies west of the ninety- eighth meridian, is the champion corn-pro- ducing county in the Union ? Was he aware that nearly one half of the wealth and pop- ulation of the State of Nebraska is to be found west of the ninety-eighth meridian? The report of the Nebraska Board of Agri- culture for the year 1889 has not been issued, but we have the report for 1888. The crops in Nebraska in 1888 were not as good as in 1889, nor was there as much ground in culti- vation. I give below some statistics taken from the report for 1888 making a compara- tive statement of the amount of wheat, corn, and potatoes raised east of the ninety-eighth meridian and west of that meridian in the State of Nebraska. It will be admitted by all that wheat, corn, and potatoes require as much moisture as do any farm products. It must be borne in mind that many of the western counties are very new and their capa- bilities not developed ; but enough is shown to completely disprove Mr. Henry's state- ments. In the counties of Nebraska that lie west of the ninety-eighth meridian there were raised in 1888 of corn, wheat, and potatoes: Corn 52,847.469 bushels Wheat 7,038.688 " Potatoes 8,626,145 " In the counties in Nebraska lying east of the ninety-eighth meridian there were raised in 1888: Cora 93,379,370 bushels Wheat 4,876,190 " Potatoes 2,724,996 " It will thus be seen that the counties west of the ninety-eighth meridian produced about thirty-six per cent of all the corn, about sixty per cent of all the wheat, and about seventy-six per cent of all the pota- toes that were raised in 1888 in Nebraska, and as a matter of fact a good portion was raised west of the one hundredth meridian. Reference to the same report shows that in 1888 there were 2,611,33V acres of improved land in the Nebraska counties lying west of the ninety-eighth meridian. These statistics clearly demonstrate that the improvements there made are far from " insignificant," and, could the statistics for 1889 be had, we would, without doubt, have a still more en- couraging showing.

Editor Popular Science Monthly : Under the above heading Mr. Reece presented some statistics in The Popular Science Monthly for January, apparently showing a high and increasing per cent of crime in those communities where there EDITOR'S TABLE. 123 were the fewest illiterates as compared with those where there were the most. In the succeeding numbers of the Monthly two writers, apparently accepting the statistics without question, have proceeded to draw conclusions from them. Some one has wit- tily said that " nothing can lie like fig- ures " ; and certainly any one who deals much with statistics knows that unless care- fully and thoughtfully handled they are capable of giving the most deceptive re- sults. For this reason startling conclusions should not be accepted without careful con- sideration. There is getting to be too wide a tendency to accept statistics as decisive proof on any subject without regard to how they were prepared or discussed. In the January Lend a Hand, Mr. David C. Torrey carefully discussed the records of crime in Massachusetts, which was one of the States where Mr. Reece found his high- est per cent of criminals, and some of his results seem worthy of quoting, as throwing much light on this subject : From 1350 to 1835 the total commitments in- creased from 8,761 to 26,651 ; in the first-mentioned year, 1 to 113 inhabitants : in the second, 1 to 72 in- habitants. It is found, however, on investigation, that the increase is almost entirely confined to crimes against public order and decency, while the commit- ments for the more serious crimes against persons and property have not even kept pace with the growth of population. The following statistics for the years since 1865 in which a census has been taken proves this statement. This division by crimes was first made in the returns to the State in 1865, and was not made in 1875: COMMITMENTS FOB CEIMES AGAINST YEAR. Persons and property. Order and decency. 1365 3,975 5,097 3,779 4,339 5,760 11,290 1370 1S80 13,274 1335 21,812 For the more serious crimes in 1S65 and 1870, the average commitments were 1 to 301 inhabitants, while in the years 1880 and 1S35 they were 1 to 436 inhabitants. The increase in commitments was for less serious crimes exclusively, and there was an actual decrease in commitments for more serious crimes, in proportion to population, of forty-four per cent. The larger portion of the less serious crimes, those for which commitments are increasing, are crimes of intemperance; so Mr. Torrey makes a sec- ond division of crimes, separating those of intem- perance from all other crimes. The returns to the State permit of this division for a longer period : YEAR. Commitments for intem- perance. Commitments for all other crimes. Total com- mitments. 1850 3.341 8,221 3,442 4.302 9,350 10,962 18,701 5,420 7.-11 8,322 5,616 7,250 6,091 7,950 8.761 1855 16,032 I860 .. 1865 11,764 9,918 1870 16,600 1875 24,548 1880 17,053 1885 26,651 This division shows that the total increase in all crimes other than intemperance, taken together, has been only fifty per cent (population not considered), but that commitments for intemperance have in- creased nearly five hundred per cent. The commit- ments which were not for intemperance are com- pared with the population of the State with the fol- lowing results : In 1850, 1 commitment to 183 in- habitants; in 1S55, 1 to 144; in 1S60, 1 to 147:. in 1865, 1 to 225; in 1870, 1 to 201; in 1875, no statis- tics ; in 18S0, 1 to 280 ; in 18S5, 1 to 244. From 1350 to 1865 the average commitments for crimes other than intemperance were 1 to 174 inhabitants, while from 1870 to 1835 it was 1 to 241 inhabitants. Thus a decrease of thirty-eight per cent is shown in all crimes other than intemperance during a period of seventeen years. The question of crime in Massachusetts thus re- solves itself into a question of intemperance, pure and simple for it is owing to intemperance alone that there is an increase of commitments. Mr. Tor- rey proceeds to show that the increasing commit- ments for intemperance do not necessarily prove an increase of intemperance. The public has a different opinion of the crime of intemperance from what it has of other crimes. The commitments for more serious crimes could not increase without an increase of those crimes ; but, because so few of the men who drink to excess are committed, there is abundant opportunity for an increase in commitments for in- temperance without an actual increase of intemper- ance. In thirty-five years public sentiment has been aroused against intemperance, and the increased commitments caused by this sentiment and the changes in law which it has brought about are the inadequate grounds which warrant claims that crime is increasing in Massachusetts. The State seems still to have encouragement to continue its schools and its reformatories and its churches, with faith that it can not only take care of the children born to it, but also that it can assimilate to its social order those which it is forced to adopt. — Boston Post.

IN" last month's Table we had a few words upon the discredit into which what is sometimes called the M or- thodox" political economy has fallen among practical men. It is a pleasure to be able to call attention to a book which furnishes a signal example of the way in which economical studies should be pursued. We refer to the volume brought out a few months ago by Mr. D. A. Wells, under the title of Recent Economic Changes. Mr. Wells is not a dogmatist, though it is evident he has sufficiently definite opinions of his own. He conceives it to be his main business to marshal the facts that seem to him capable of explaining the present mate- rial condition of society, and of indi- cating the course that things are likely 124 THE POPULAR SCIENCE MONTHLY. to take in the future. He has no spe- cial theory to advocate, and he prom- ises no speedy renovation of society if only his advice be taken. He knows too much to be a visionary ; he has too firm a hold on the actual to be carried away by the merely ideal or fanciful. He finds no fatal flaw in the present so- cial system ; he does not see, in fact, how, given human nature as it is, things could be very different from what they are. At the same time he is an earnest be- liever in progress ; but he thinks that progress depends more npon individual adaptation to necessary conditions of existence than upon any cunningly con- trived devices for an improved distri- bution of the products of industry. In a word, he is a man whom the devour- er of contemporary socialistic romances would tind a little dull, but whom the practical man of business would find both interesting and instructive in the highest degree. As a large part of Mr. "Wells's book appeared originally in the pages of this magazine, we may pre- sume that many of our readers have a more or less vivid recollection of the course of his argument. What Mr. "Wells set himself chiefly to do was to trace to its cause or causes the present disturbed condition of the world from an eco- nomic point of view. Given such a problem, a writer who wished to create an immediate sensation would bring forward some theory about the land, or about the currency, or about monopo- lies, or about the waste involved in com- petition, and would declare with much emphasis and vainglory that he alone had the true key to the whole situation. Mr. Wells is more modest. All he pro- fesses to see is that the rapid pace of invention and discovery in the modern world is sufficient to account for enor- mous vicissitudes both in the money market and in the labor market. Capi- tal has been destroyed in huge blocks and recreated by new methods; labor has been forced to quit one employ- ment after another and find new open- ings for itself. The course of business has become more and more difficult to calculate, and only the stronger heads and more resolute wills have been able to hold their own amid the changes and chances of the hour. Mr. Wells does not deal in mere gener- alities. He treats separately each aspect of his subject, and under every head gives facts in abundance — "modern instances," as Shakespeare expresses it. He shows what has been done in the way of open- ing new routes ; and, in the case of the Suez Canal, he traces to that one cause the most momentous results as regards the course of trade. He discusses very fully the effects of the cheapening of transportation by land and by sea, show- ing how, to this cause, must be attrib- uted much of the agricultural depression existing in different parts of the world. He dwells on the inventions and dis- coveries by which manufactures have been cheapened, and labor constantly displaced and again provided for. He shows how improved methods of farm- ing render less efficient ones unprofit- able, and how little good has been done to the farming population by the home- stead and other exceptional laws passed for their benefit— nay, how they have been injured by the overzeal of their friends in the Legislature. He discusses the effect of restrictions on trade, and shows in what idle fashion the govern- ments of the world, with one or two ex- ceptions, handicap their own commerce in the effort to injure that of their neigh- bors, and how the effect of the whole protectionist madness is simply to place a heavy drag upon the industrial energy, not to say upon the conscience, of man- kind. We can not pretend, however, in this place to give even the most rapid summary of the contents of Mr. Wells's volume. Suffice it at present to say that he has described with great fullness and, so far as we can judge, with great accu- racy, the conditions under which the business of the world is now being car- ried on, and the circumstances that have EDITOR'S TABLE. 125 concurred to make the present epoch one of peculiar commercial and industrial unrest. What is the lesson, then, we are to draw from Mr. "Wells's pages, so far as the social problems of our own time are concerned ? We learn from it that there is nothing radically unsound in our social system ; and, further, that the total effect of all the changes of the last twenty-five or thirty years has been to improve materially the condition of the working classes. Hours of labor are not as long on the whole as they used to be ; wages are higher ; and the pur- chasing power of money is greater. What is the case, however, is that, in the rush of change which has marked recent years, there is a constant selec- tion and reselection of the better men, and that the worse — the less competent, the less efficient in every way — find them- selves relegated to poorer conditions of life. There is an upward current and there is a downward current : those who move up do not spend much time or en- ergy in singing the beauties of the pres- ent system ; but those who are moving down waste no small amount of the little energy they have in bewailing its de- fects, and, with the help of a few liter- ary gentlemen of lively sympathies and facile speech, manage to create a wide- spread impression that a world in which they do not get all they would like must be a very badly governed world indeed. The whole social question seems to lie here, that some, through natural defi- ciencies of one kind or another, can not, in any satisfactory degree, adapt them- selves to the world as it is. We should be sorry to profess, or to feel, indiffer- ence to the problem even as thus stated ; but what are we going to do about it ? The true methods of reform are of slow application ; and immediate suffering it is impossible altogether to prevent. The path of social reform, we are strongly persuaded, lies mainly along these three lines : 1. Diminution of state interference with private liberty, including state re- strictions on trade and state encourage- ment of trade. 2. Constant inculcation of the doc- trine of individual responsibility, and constant effort to mold better individ- uals. 3. An honest, vigorous, and simple administration of justice. These three conditions (to which many minor but still important ones might be added) are all intimately con- nected. For example, how can we preach the doctrine of individual re- sponsibility with any success, if the in- dividual is daily surrounded by a closer and closer network of arbitrary enact- ments, designed at once to abridge his liberty and to relieve him of the exer- cise of judgment and caution ? And how can we have a really efficient adminis- tration of law, till law itself undergoes a pruning, and is brought down to its necessary elements? To return, however, to Mr. Wells's book. We are glad to see its merits very frankly acknowledged in an article published in the March number of Mac- millan's Magazine, the writer declaring that Mr. Wells deals with his subject " in a manner altogether superior to any- thing which this country (England) can show." We shall only say in conclusion that the book is an eminently useful one to-day and will remain so for many years to come. A careful perusal of its pages would clear infected brains of many sickly fancies. TRAINING IN REALITIES. It is a long time since an earnest thinker proclaimed that wisdom was the principal thing, and that with all a man's gettings he should strive to get under- standing; but whether the world to-day — even those who regard the utterance as carrying with it more than human authority — can be said to pay due heed to the maxim is more than doubtful. Instead of wisdom, men exalt opinion, 126 THE POPULAR SCIENCE MONTHLY. and traditions are taught where truth should be explored. We have large and influential schools decrying the use of reason, and we have millions of people to-day trying to think true what their common sense tells them is not true. All this does not make for the world's peace or stability. It will not be really well with society until men generally are brought to recognize that there is such a thing as truth, and that its claims upon them are paramount. Our systems of education need to be revolutionized. "When a young person leaves school or college nowadays, do we expect to find that his or her judgment has been de- veloped in practical things ? Do we ex- pect to find a keen sense of what is true, a quickness in distinguishing shams from realities, and a well-established habit of yielding, upon all disputed questions, to the greater weight of evidence ? Nothing of the kind. We look for a little knowl- edge of arithmetic and mathematics generally, a modicum of geography and grammar, a smattering of literature, a few confused notions of natural science, a dis- continuous skeleton of historical knowl- edge, and not much else. The judgment has not been trained, the sense of truth has not been trained, nor has any insight worth mentioning been given into the realities of life and duty. We do not blame the teaching fraternity for this ; society as a whole is responsible. The want of interest in truth as truth, the lack of perception of its importance, is a broad social characteristic of the time, and floods the schools just as it floods the market-place, the press, and the pul- pit. But, while we do not in any special manner blame the teaching profession, we feel like summoning all serious men to consider whether a very decided and vigorous effort should not be made to place our schools upon a higher level in this respect. No one can doubt that, if our minds were set upon it, a sim- ple gymnastic might be devised which would, from the outset, train childish minds in the perception of truth and lead them on from stage to stage in the acquisition, not of sham but of real knowledge. A child in course of edu- cation should never be removed from actual contact with the world about him. He should be made to feel that every general rule given to him is merely a summary expression of a number of con- crete examples. He should be early familiarized with the method of proof, and in every possible way encouraged to ask for proofs. He should be made to realize the activity of his own senses ; to feel that knowledge is coming to him through those avenues ; and that, only as it so comes, is it entitled to be con- sidered real knowledge. Such a system of education as we have hinted at would banish the intel- lectual poverty and squalor of our time; and this could not be done without an immense improvement of general social conditions. The sentimentalists of our day bestow a huge amount of sympathy upon the victims of poor wages ; but they do not grieve as they might over the victims of poor thoughts and disor- dered imaginations. The dust and dirt heaps that obstruct the entrance to thou- sands of minds are not visible as material masses ; but they are there all the same, and the injury they cause is greater than any due to mere limitation of material conditions. The land is full of delusions, and scarcely anywhere do we see any clear consciousness of the grand possi- bility open to the human race of co-op- erating in the discovery and application of truth, including, of course, and in the first place, the laws of social well-being. "We too readily resign ourselves to the idea that men's opinions must differ by the whole circle of possible thought, and that a common standard of truth is un- attainable. Well might the reproach be launched against this generation, " O ye of little faith ! " Amid the manifold and ever-widening discoveries of science we resign ourselves to intellectual chaos, as if there were no common heritage of truth for us all, or as if human minds LITERARY NOTICES. 127 were not all made essentially on the same pattern. What the times seem to call for is some association of men and women bent on nothing else than the introduction, primarily into our educa- tional systems, but as much as possible into social life generally, of a supreme regard for that which is real. LITERARY NOTICES. Practical Hints for the Teachers op Pub- lic Schools. By George Howland. In- ternational Education Series, Vol. XIII. New York : D. Appleton & Co. Pp. 198. Price, $1.50. This volume deals with the practice rather than with the theory of education. It tells what to do, and does not concern itself with any comprehensive scheme of educa- tional philosophy. The author is superin- tendent of the public schools of Chicago, and the several chapters of this volume are based upon papers read before the teachers of that city and vicinity. The author has not aimed to produce an exhaustive and systematic treatise, but has confined his at- tention to the following ten topics : Moral training in city schools, the character of the teacher, the place of memory in school instruction, elements of growth in school- life, the scholarship aimed at in the school, the teacher in the school-room, how the school develops character, the class recita- tion, the school principal, and the work of the superintendent. The pages of the book are dominated by the personality of the au- thor, and the things and practices recom- mended are such as his experience tells him are good. In regard to moral training, the subject that he treats first, he has no faith in text-books or special instruction ; he would trust entirely to " the quiet suggestion, the fitly chosen word, the interested inquiry, the look, the unfeigned sympathy, the favored opportunity, the firm but calm decision of the loved and loving teacher." In other subjects, however, he would depend al- together upon books. The sesame to all progress, he says, is found inscribed on the printed page. In the six years before the child comes to school he has had a training without books which, as Mr. Howland affirms, has been very effective. " He has early learned that fire will burn, that cold will freeze, and knows, beyond the power of Webster or Worcester to tell him, the mean- ing of burn and freeze ; and by many a bump has the force of attraction been im- pressed upon him." He has learned a lan- guage, and has acquired much other knowl- edge. By similar means the Indian acquires a wonderful training of his senses, his hands, and his mental powers. " He learns to do," says Mr. Howland, " in the only true way, by the doing." In acquiring a knowledge of language the author recommends this same process. Correct use of words and a nice appreciation of their meanings and force are to be secured, he says, " not from dictionary, but from use alone." That the teacher should learn by this method, how- ever, he deems inadmissible. In his chap- ter on " The School Principal " he says : " We learn to do by doing, is one of those aphoristic half-truths well suited to catch the ear and delude the mind of the un- thinking. We may acquire a mechanical facility by repeated doings of what we al- ready know how to do, but we learn to do by learning how other people do, and by the aid of this knowledge striving to do some- thing better." The volume is especially marked by an energetic character and a confident tone which assure the reader of the real interest of the author in the work of the teacher. First Lessons in Political Economy. By Francis A. Walker. New York : Henry Holt & Co. Pp. 323. Price, $1.25. The special purpose of this book is to bring political economy within the grasp of youth from fifteen to seventeen years of age. The author has not made it childish by re- stricting himself to " words of two sylla- bles," or by any similar device. The char- acter which he has aimed to give the volume in order to adapt it to young pupils consists in " a clear arrangement of topics ; a simple, direct, and forcible presentation of the ques- tions successively raised ; the avoidance, as far as possible, of certain metaphysical dis- tinctions which the author has found very perplexing to students of even a greater age ; a frequent repetition of cardinal doctrines ; and, especially, a liberal use of concrete illustrations, drawn from facts of common 128 THE POPULAR SCIENCE MONTHLY. experience or observation." The fact that one purpose of the treatise is to interest be- ginners in the subject of political economy has also modified its character. " The author has not held himself, as strictly as he has sought in previous works to do, to the treat- ment of political economy as a science, to be distinguished from the art of political econ- omy. He has allowed himself great freedom in assuming that certain results are desirable in themselves, and certain other results un- desirable ; and he has sought to show how these may be avoided and those attained. Much, which, in his other works, has been treated as belonging to the applications of political economy, is wrought into the sub- stance of the present treatise." The work is divided into two chief parts, one treating of " Production and Exchange," the other of " Distribution and Consumption." Each section is numbered and has a title, and the volume is indexed. Fuel and its Applications. By E. J. Mills and F. J. Rowan. Illustrated. Phila- delphia : P. Blakiston, Son & Co. Pp. xx + 802. Price, $7.50. It is one of the obstacles to gaining a competent knowledge of technology that its manuals become almost worthless when a few years old, but it is the glory of the sci- ences on which technology depends that they advance fast enough to make these books antiquated so quickly. This is espe- cially true of the group of industries based upon the science of chemistry. In order to supply the lack of a comprehensive, authori- tative new work dealing with these indus- tries, a series ' of volumes has been pro- jected, under the general title "Chemical Technology, or Chemistry in its Applica- tions to Arts and Manufactures." It will be edited by Charles E. Groves, F. R. S., editor of the " Journal of the Chemical So- ciety," and William Thorp, B. Sc. As much of the matter of Richardson and Watts's "Chemical Technology " as is available, es- pecially the historical portions, will be incor- porated in the new work. Of this series the present volume is the first. The most im- portant sections of the general field, to be covered in later volumes, are "Lighting," "Acids and Alkalies," "Glass and Pottery," "Metallurgy," "Textile Fabrics," "Leather, Paper, etc.," " Coloring Matters and Dyes," "Oils and Varnishes," "Brewing and Dis- tilling," "Sugar, Starch, Flour," etc. The present volume treats of "Fuel and its Ap- plications " generally ; its special employ- ment in various branches of chemical manu- facture being preserved for detailed consid- eration in the volumes devoted to the special subjects enumerated above. In the chapters devoted to the production of fuel, tables are given showing the composition of the differ- ent woods and coals, together with informa- tion concerning the formation of peat, lig- nite, and coal, the world's production of coal, explosions in mines from fire-damp and coal- dust, etc. The figures representing the out- put of coal in Britain and other countries show the enormous development which has taken place in the fuel industry all over the world. Methods of burning charcoal, both in heaps and kilns ; and methods of coking, in heaps and in ovens, are described, with illustrative views and diagrams. On the continent of Europe, methods of cleaning, washing, and classifying coal have reached a great degree of elaboration, and the prac- tice in Britain has progressed somewhat in the same direction. Considerable space is devoted to these methods, and the machines employed in them. The most marked ad- vance in respect to the manufacture and application of fuels in the past generation has been in the control and utilization of gases. The waste gases from coking ovens are now collected for their ammonia, tar, and other by-products, the gases from blast- furnaces using coal and from gas-producers are also made to yield these products ; and great advance has been achieved in the ex- traction of ammonia in shale distillation. More important than these is the use of coal-gas, and in America of " natural " gas also, as fuel. The methods and appliances for using gaseous and also liquid fuel re- ceive a general representation in this vol- ume, and copious references are given for specialists who may wish to study particular branches of the subject. The portion of the volume devoted to the application of fuel is introduced by chapters on the theory of heat and the nature of flame. The matters of chimney - draught, forced combustion, and smoke prevention are then taken up. The special application of fuel considered first LITERARY NOTICES. 129 is in domestic heating. The open fireplace and several ventilating fireplaces, and the " American " stove, are mentioned ; but most space is given to gas heating and cooking stoves. Heating by means of hot air, hot water, and steam also receives attention. The application of fuel to vaporization, i. e., the heating of boilers, is next treated ; and from this subject the authors pass to the evapora- tion of liquids and distillation. The drying of wood and malt, baking bread, and firing brick and porcelain, also have a place. Fur- naces for metallurgical and other technologi- cal operations are next treated, and an im- portant chapter follows on gas-furnaces, in- cluding those using the regenerative prin- ciple. The closing chapter deals with the practical effect of fuel. A series of tables giving analyses of coals follows. Through- out the book exact information in regard to the several divisions of the subject is fur- nished in tables and diagrams. The volume contains seven plates and six hundred and seven other illustrations, and is provided with an adequate index. Liberty and a Living. By Philip G. Hu- bert, Jr. New York and London : G. P. Putnam's Sons. Pp. 239. This book is described in its sub-title as the record of an attempt to secure bread and butter, sunshine and content, by gardening, fishing, and hunting. One of its mottoes is, " The royal peace of a rural home." The author, a writer on New York newspapers, wearied with the monotony and drudgery of city life, sought a way in which he could spend his time in the outdoor season prof- itably in the open air, and without giving up the winter residence in the city which his profession demanded. He found a place on the sea coast of Long Island which af- forded a home, garden, wood-lot, access to the water for boating and fishing, and hunt- ing privileges. The book describes his life there, and the moral and practical lessons derived from it. The transcript of the diary of a week gives a realistic picture of the average life. The home and its arrange- ments, the garden-work and its returns, the fishing, the bee-raising, the advantages de- rived from the possession of a wood-lot, and the balance of advantages and disadvantages, are described in successive chapters. The vol. xxxvii. — 10 balance is shown to be decidedly in favor of the country, pre-eminently so to those who seek quiet, rational enjoyment, with health, who desire leisurely culture without excite- ment, who are willing to live independently of fashion, and who do not attach an exag- gerated importance to show. Jonathan Edwards. By Alexander V. G. Allen, D. B. Boston and New York : Houghton, Mifflin & Co. Pp. 401. Price, $1.25. This is the first volume of the series of "American Religious Leaders," or biogra- phies of men who have had great influence on religious thought and life in the United States, in which it is intended, besides de- picting great figures in American religious history, to indicate the leading character- istics of that history, the progress and pro- cess of religious philosophy in America, the various types of theology which have shaped or been shaped by the various churches, and the relation of these to the life and thought of the nation. The present volume relates to the earliest and probably the greatest of those leaders — the thinker who, along with Benjamin Franklin, American and foreign critics agree in naming as representative of American intellectual activity in the eight- eenth century. Prof. Allen's aim in this bi- ography has been "to reproduce Edwards from his books, making his treatises, in their chronological order, contribute to his por- traiture as a man and as a theologian." Some- thing more than a mere relation of facts seemed to be demanded in order to justify the endeavor to rewrite his life. What we most desire to know is, what he thought, and how he came to think as he did. " Ed- wards is always and everywhere interesting, whatever we may think of his theology. On literary and historical grounds alone no one can fail to be impressed with his imposing fig- ure as he moves through the wilds of the New World." Edwards's life is full of dramatic incident, and his writings furnish ground for fruitful study — a study which he that would understand the significance of New England thought in the last century, and un- der its later aspects as well, will find indis- pensable. The summation of the result of Edwards's work is concluded with the asser- tion that " all who accept the truth that divine things are known to be divine be- 13° THE POPULAR SCIENCE MONTHLY. cause humanity is endowed with the gift of direct vision into divinity, are accepting what Edwards proclaimed, what constitutes the positive feature of his theology. There are those who have made the transition from the old Calvinism, through the mediation of this principle, to a larger theology as if by a natural process. Among these typical think- ers were Thomas Erskine, McLeod Camp- bell, and Bishop Ewing in Scotland, or the late Mr. Maurice in England. These and such as these, in whom the God-conscious- ness is supreme, are the true continuators of the work of Jonathan Edwards." Exercises in Wood-working; with a Short Treatise on Wood. By Ivin Sickels. New York: D. Appleton & Co. Pp. 158, with Plates. This book is written for manual train- ing classes in schools and colleges, having been prepared in the first instance in manu- script for the students in the College of the City of New York. The manuscript was copied for other schools. Many changes and additions were made under the suggestions of subsequent teaching ; and it is now print- ed and published, for all who desire a vol- ume of the kind. Being the product and result of work in teaching, it could hardly be other than a working book ; and a work- ing book, so far as it reveals itself to a critic's ken, it is. Its scope is the presentation of the facts which are most essential to the wood-worker's success and the good execu- tion of his work, and of directions for the use of his tools and for manipulation. These facts and directions are given in a simple, concise style, intelligible to any pupil of or- dinary sense. The book deals particularly with carpentry and joinery, and is divided into two parts. The first part treats of the structure, properties, and kinds of wood ; its manufactures and economic relations to other substances ; parasitic plants and in- sects, and means of preserving wood ; under these heads are articles on the structure and composition of wood, branching of stems, age of trees, their decay, the season for cutting, milling, drying, and warping, the properties and defects of wood, its measure and values, and the kinds of wood. The several species used in wood-work, coarse and fine, are named and described; their value is estimated, their special qualities are pointed out, and the purposes indicated to which they are applied. This is followed by a tabular exhibit of the qualities of the va- rious kinds of wood. A few words are given to the relations of wood and iron, and the wood-working trades are mentioned, and car- pentry and joinery defined. A description of parasitic plants or fungi injurious to living trees and lumber follows ; an account of in- jurious insects, prepared expressly for the book by Mr. Bashford Dean, and directions concerning the preservation of wood are given. The second part contains the exercises, pre- ceded by a description of tools. The directions for the care and use of tools are explicit, and are illustrated by drawings representing the method of handling each tool, and the mark it makes. These exercises are followed by those concerning the forming and fixing of the several kinds of joints, gluing, making boxes, with hinging tops, drawers, and gen- erally on uniting several pieces to make a complete structure; a series on the details of ordinary house carpentry, whence models may be constructed and the building of the various parts making up a wooden dwelling learned; the use of the frame-saw and meth- ods of bending wood ; pattern-work ; shap- ing (boat model) by the use of templets ; and veneering, with directions for painting and polishing. The National Medical Dictionary. Two vols. By John S. Billings, M. D., etc., and Collaborators. Philadelphia : Lea Brothers & Co. Price, $12. This work aims to define " every medical term in current use in English, French, Ger- man, and Italian medical literature, including the Latin medical terminology of all of these languages." The pronunciation' of English and Latin terms is indicated, and the deriva- tion of most English and Anglicized Latin words (except names of drugs and plants) is given. The dictionary does not attempt to be cyclopedic, but gives simply brief defi- nitions of the words and phrases included in its list. Prefixed to the first volume is a number of tables, including a table of doses, of antidotes, of the inch and metre system of numbering spectacle-glasses, of thermo- metric scales, of the average dimensions of the foetus at different ages, of the average dimensions of the parts and organs of the adult human body, and of the weights of the LITERARY NOTICES. 131 organs. Among these tables, also, there is a series, prepared by Prof. W. 0. Atwater, showing the percentages of nutrient ingredi- ents in a large number of food-materials, the fuel-values in the same, and standards for dietaries for different classes and occupa- tions. Another table shows the expectation of life as derived from records of life-insur- ance companies, and from the last United States census. The Anatomy op the Frog. By Dr. Al- exander Ecker. Translated, etc., by George Haslam, M. D. Illustrated. Ox- ford : Clarendon Press ; New York : Mac- millan & Co. Pp. 449, with Colored Plates. Price, $5.25. The frog is aptly designated by the au- thor as eminently the physiological domestic animal. It is kept in every physiological laboratory, and is daily sacrificed in num- bers on the altar of science. The physiolo- gist has recourse to it, not only to obtain an- swers to new questions, but for the sake of demonstrating easily and quickly the most important known facts of the science. It has furnished the means through which many most important discoveries in physiology have been made. It has " afforded almost the only material for the investigation of the excita- bility of nerves and its associated electro- motive changes, and also no inconsiderable part of the remaining nerve and muscle physiology." Much of our knowledge of the functions of the spinal cord is derived from experiment upon it. Its muscles have served for the investigation of the phenomena and the conditions of contraction. But for the web of its foot and the gills and tail of its tadpole, " we should not perhaps for a long time have arrived at a satisfactory knowl- edge of the existence and the conditions of the capillary circulation. Acquaintance with the constituents of the blood directly con- cerned in nutrition ; important facts in the physiology of the blood and lymph ; and in- sight into the laws of the heart's action, have all been obtained by observations and experiments on the frog. To it, also, in his- tology, we owe much of our knowledge of the structure of nerve-fibers, their origin and termination, their relations within the ganglia, and the structure of muscular fiber ; and for the study of reproduction and devel- opment the frog has, next to the chick, af- forded the most important material." The importance of students being well acquaint- ed with the anatomy and structure of an ani- mal which plays so prominent a part in their researches is obvious ; and it is this which Dr. Ecker, who is Professor of Human and Comparative Anatomy in the University of Freiberg, and Dr. Haslam, have furnished in the present book. The original work of Prof. Ecker was published in 1864. A second part, embodying, besides the author's work, fruits of the researches of Prof. Wieders- heim, appeared in 1881-82. The transla- tion was undertaken by Dr. Haslam at the suggestion of Prof. A. Gamgee, and was ac- cepted by the delegates of the Clarendon Press as one of the series of Foreign Bio- logical Memoirs published by them. But it soon became evident that a mere translation would be unsatisfactory, and that it would be desirable to recast and modify parts of the book, and to give descriptions of the minute structure of the several organs. The translator has included the results of recent researches, and has added facts derived from his own observations. The Elements op Astronomy. With an Uranography. By Prof. Charles A. Young. Boston : Ginn & Co. Pp. 470. Price, $1.55. Prop. Young has prepared this text-book for use in high schools and academies, using in it much of the material and many of the illustrations of his larger work, General As- tronomy. The author has tried to avoid going to an extreme in cutting down and simplifying, while giving a clear treatment of every subject. From the number of pages in the book it may be inferred that he has provided abundant material for a high- school course in astronomy. He has paid special attention to making all statements correct as far as they go, though many of them, on account of the elementary charac- ter of the book, are necessarily incomplete. No mathematics higher than elementary algebra and geometry is introduced into the text. In an appendix of some seventy pages, methods of making certain calculations and the construction of astronomical instruments are described. The Uranography comprises a brief description of the constellations vis- ible in the United States, with four maps, from which the principal stars may be iden- 132 THE POPULAR SCIENCE MONTHLY. tified ; also a list of such telescopic objects in each constellation as are easily found, and lie within the power of a small telescope. The volume is illustrated with one hundred and fifty-eight cuts. American Spiders and their Spinning-Work. Vol. I. By Henry C. McCook, D. D. Published by the Author: Academy of Natural Sciences, Philadelphia. Pp. 372. Price $30 (set of three volumes). The naturalist who takes dried or alco- holic specimens as the subjects of his study can prosecute his researches at all times and seasons, and independently of the will of the creatures that he is studying. But this ad- vantage is offset by the limitation that the habits of the creatures, the kind of places they live in, the sort of structures they make, the way they move about, obtain their food, and rear their young, are a sealed book to him. The observations of the field natural- ist, on the other hand, are attended by many more difficulties than those of the laboratory student. He must go to his specimens in- stead of having them brought to him. Per- haps they are not to be found at all seasons, and, when they are accessible, many hours must be spent in watching familiar actions in order not to miss a chance of seeing a new operation. He has the compensation, however, that he studies the creatures alive ; hence the things which are hidden from the laboratory naturalist are revealed to him, and the knowledge that he gains arouses the widest interest and wins the greatest appre- ciation. The results which Dr. McCook lays before us in the present volume belong mainly in the latter class. They relate to the spinning-work of spiders, as performed in the making of webs and dens. With this is naturally connected some account of the methods of procuring food and the nesting- habits of these creatures, and the intelli- gence that they display in adapting their operations to particular circumstances. In order to give the reader a correct idea of how spiders form their threads, a fully illus- trated chapter on the structure of the spin- ning-organs has been introduced. The whole work will be confined to the orb-weavins: spiders of the United States, but a vast amount of material relating to other tribes, which the author has collected, has been drawn upon in order to make comparisons between the habits of the orb-weavers and other spiders. To the general reader, who sees no important difference between any two common wheel-shaped spider-webs, the distinct varieties of orb-weavers' snares de- scribed by Dr. McCook will be a revelation. Artists, too, who are supposed to be careful about the correct shapes of the things they draw, seem to have looked only carelessly at spiders' webs, for our author states that he has never seen but one in art work or book illustrations that gave proof of having been drawn from a natural web, by one who knew its characteristics. In three chapters the general features, the mode of constructing in detail, and the armature of orb-webs are presented. Passing to varieties of the orb, Dr. McCook describes the web with its center of closely woven silk tis- sue and a zigzag ribbon extending upward and downward, which is made by Argiope, a spider whose large size and beautiful mark- ings make it conspicuous in our autumn fields. The round vertical webs made by Epe'ira and other spiders are then touched upon. An account is given of the composite snares, which consist of a wheel-shaped web combined with a maze of intersecting lines ; also of the sectoral orb, in which there is always one division of the wheel that is not crossed by the concentric rings. Among the other peculiar features in webs that the author describes are the domed orb of the basilica spider, the ribbon decorations of the feather-foot, the triangle or part of a circle constructed by the triangle spider, and the somewhat irregularly radiating snare of the ray spider. A chapter on the engineer- ing skill of spiders gives instances of their using weights to hold their webs taut, their placing of stay -lines in the best position al- lowed by circumstances, using unfamiliar substances for building a nest, etc. Espe- cially interesting is a chapter on the me- chanical strength of webs and the physical power of spiders, in which cases are given of spiders capturing and hoisting from the ground animals many times as large as them- selves. Other topics that are fully treated, but which can be only mentioned here, are feeding habits, uses of poison, and nest- making habits. In a concluding chapter on the genesis of snares, the author traces the relations which exist between the various LITERARY NOTICES. J 33 forms of spinning-work treated in the fore, going pages. The volume contains three hundred and fifty-four illustrations, the au- thor being convinced that a drawing is bet- ter to communicate some facts than pages of words. The pictures, moreover, are of artistic quality, and the mechanical work of the volume is of a high grade, making the book a remarkably handsome one. In the second volume of this work the author will treat the habits and industry associated with mating and maternal instincts, life of the young, etc. The third volume will be a sys- tematic presentation of the orb-weavers of the United States, the descriptions being ac- companied by a number of lithographic plates colored by hand. The work, aside from its scientific value and its popular in- terest, will be a treasure to the library of any one who secures a copy. The " author's edition " is limited to two hundred and fifty numbered copies, which are issued in cloth with uncut edges. A large part of the edi- tion had been subscribed for before publi- cation. The Report of S. P. Langley, Secretary of the Smithsonian Institution, for 1889, states that the income of the Smithsonian fund is becoming less and less adequate for the work of the Institution with each year of the country's growth. This fund is now $703,000, of which only $1,500 have been received in bequests since the original Smith- son legacy. The secretary calls attention to the Institution as a suitable trustee for moneys intended for the advancement of knowledge. Additional space is needed for exhibition purposes for the National Museum. The appropriation allowed for making the foreign exchanges required by Government does not cover what this service costs the Institution, even though free transportation is given by many steam- ship companies. The library received 17,- 354 accessions in the course of the year, and the collection is so large that much of it is inaccessible from lack of room. The collec- tion of living animals, which numbers over three hundred, has outgrown its accommoda- tions, and a scheme for creating a zoologi- cal park on Rock Creek, in the District of Columbia, is being agitated. The report in- cludes statistics of publications of the Insti- tution during the year, of accessions to the museum and to the library, and of interna- tional exchanges. A great many facts which chemists con- stantly need to refer to are put into handy shape in the little pamphlet which Prof. John H. Appleton has published now for eight years, called the Laboratory Year-Book (G. Roscoe and Co., Providence, 12 cents). This publication contains a calendar, notes on the chemical work done in the preceding year, a list of new elements announced since 1877, a table based on the latest revision of atomic and molecular weights, tables of weights, measures, and thermometer scales and equivalents, the C. G. S. system of units, pronunciations of words used in chemistry, logarithms, postal regulations, etc. The Meteorological Observations made on the Summit of Pike's Peak, January, 187 4^ to June, 1888, are published in the Annals of Harvard College Observatory, Vol. XXII. The observations were made and were pre- pared for the press by the United States Signal Service, and the expense of publica- tion has been borne by the Boyden fund. The observations occupy four hundred and fifty-eight quarto pages, and are introduced and supplemented by a few pages of text. The Observations of the Neio England Meteorological Society for 1888, published in the Annals of the Harvard College Observa- tory, contains tables in which the work of the society for the year is summarized. In a general account of the weather of the year it is stated that nine months were colder and three warmer than the average in New England. The total precipitation exceeded the usual annual fall by twenty-five per cent. Among the papers that have appeared in recent numbers of The Modern Science Es- sayist (James H. West, Boston ; 10 cents a number) is one on The Scope and Principles of the Evolution Philosophy, by Lewis G. Janes, the first lecture of the Brooklyn Ethi- cal Association's second season. Dr. Janes represents evolution as a universal method, explaining the processes of all activity. He states the agnostic position in regard to the Unknowable Cause, and denies that the evo- lutionist is a materialist. In his closing paragraphs he points out the kind of aid that evolutionary philosophy can give to the solution of the problems of society. The 134 THE POPULAR SCIENCE MONTHLY. Moral and Religious Aspects of Herbert Spencer's Philosophy are presented in a paper by Sylvan Drey, under three heads: First, Spencer's theory of religion; second, Spencer's theory of morality ; third, the re- lation of religion to morality from the Spen- cerian point of view. The object of the essay is exposition and not defense, and the author has the happy faculty of clear state- ment, which such work requires. In a lect- ure on Primitive Man, Z. Sidney Sampson sketches the life-record of man as it is re- vealed to us by the flint implements belong- ing to the Pleistocene and possibly to earlier geologic periods, by the articles found among the piles in the Swiss lakes, etc. The lect- ure is devoted mostly to the discoveries and conclusions relating to the earlier Old and New Stone Periods. C. Staniland Wake de- scribes The Growth of the Marriage Rela- tion, giving the attitude of primitive peoples toward consanguineous marriage, some of the varieties of polygyny and of polyandry that have obtained in various countries, and the chief features in the growth of monog- amy. Two successive volumes of the Questions of the bay series are devoted to " the rail- way problem." One of these, by Hon. W. D. Dabney, is entitled The Public Regulation of Railways (Putnams, $1.25). It deals with the commercial relations of the rail- ways to the public, and does not take up the regulation of the roads with reference to safety and convenience. The author dis- cusses first the legal aspects of the ques- tion and then its economic aspects. Un- der the former head are considered the sources of legislative power over railroads, and the limitations of this power arising from charter contracts, from the property rights of the owners of railways, and from the powers of Congress over interstate commerce. On these subjects, the decisions of the United States Supreme Court are taken as authority almost exclusively. On the economic side the discussion is based principally upon material contained in the reports and decisions of the Interstate Com- merce Commission, and in the testimony and arguments presented to that body in the re- port made and testimony taken by the "Cullom Committee" of the Senate, and various other reports. The closing chapters contain a brief analysis of the Interstate Commerce Act, and a consideration of the relations of the express companies to the railways and to the people. The phase of the subject dealt with by Mr. John M. Bonham concerns Railway Se- crecy and Trusts (Putnams, $1.25). The secret discounts that railways make to cer- tain monopolistic manufacturing corporations the author regards as the most serious feat- ure of the railway problem. In his discus- sion of the subject he traces the growth of abuses in railroad management, showing that they owe their existence to the faulty system under which railroad charters have been granted. He states that the commis- sions that have been appointed to regulate great trusts and corporations fail to accom- plish any reform because they have not the power to get at the secret agreements of these bodies, and he recommends a system of inspection which will prevent the unjust favoritism complained of. The Report of the Commissioner of Edu- cation for 1887-88 is about as late in ap- pearing as that of the preceding year, although it was completed three months earlier. The efforts and appeals of Com- missioner Dawson for prompt publication of this document should meet with better suc- cess. Among the topics that receive special attention in the report are the condition and needs of education among the thousand Metlakahtla Indians, who have recently re- moved from British Columbia to an island near Sitka, also among the other inhabitants of Alaska. Manual training, industrial in- struction, and education at the South, are also carefully reviewed. A course of lectures on the Constitutional History of the United States, as seen in the Development of American Laiv (Putnams, $2), delivered at the University of Michigan, has been published in book form. The subjects and lecturers are as follows : The Federal Supreme Court : its Place in the American Constitutional System, by Judge Thomas M. Cooley; Constitutional Development in the United States as influenced by Chief-Justice Marshall, by Hon. Henry Hitchcock ; as influ- enced by Chief -Justice Taney, by Hon. George W. Biddle ; as influenced by the Decisions of the Supreme Court since 1865, by Prof. Charles A. Kent ; and The State Judiciary : LITERARY NOTICES. 135 its Place in the American Constitutional System, by Hon. Daniel H. Chamberlain. The treatise on Money, by James Piatt (Putnams, 75 cents), is historical, commer- cial, and economic in scope. It gives a sketch of the origin of money, after which the question, What is money ? is discussed. The author defines money as " a commodity, of the same general nature as all other com- modities." But he says that, although a wealth in itself, its utility consists in its ready convertibility. Paper is not money, according to his view. Considerable space is devoted to explanations and counsel about banking. Exchange and interest receive attention, and the author then proceeds to discuss wealth and capital. Some consider- ations on panics are given, with the aim of preventing the tight grip on money that always aggravates a panic. In the closing sections, means of attaining individual suc- cess and national prosperity are pointed out. The History of Federal and State Aid to Higher Education in the United States has been prepared by Frank W, Blackmar, Ph. D., at the request of the Bureau of Educa- tion, as one of the series upon the history of higher education in the United States, au- thorized by the Secretary of the Interior. It is intended to represent the progress of the State idea in education from the founda- tion of the colonies to the present time. It discusses the rise of national education, with its relation to local, and brings forward the opinions of statesmen and scholars concern- ing the duties and functions of government in public education. A brief history is given of the methods adopted by Congress to en- courage and assist institutions of learning, while the main body of the work is devoted to the presentation in a condensed form of the plans pursued by the Legislatures of thirty-eight States in the treatment of higher education. One of the strongest inferences drawn by Commissioner Dawson from the investigation is that in nearly every instance the foremost desire of the people has been for colleges and universities rather than for schools of a lower grade, the opinion having prevailed that primary and secondary schools were dependent for their existence on higher institutions. The Twenty-seventh Annual Report of the Massachusetts Agricultural College gives an account of the work of the institution dur- ing 1889, with the usual information about course of study, professors, equipment, etc. Appended to this report is a paper by Prof. Paul Wagner, of Darmstadt, On the most Profitable Use of Commercial Manures, translated by Prof. Charles Wellington in answer to the demand for information on the subject. In The Evolution of a Life (Holt Pub- fishing Company, $2), Henry Truro Bray tells the story of his early life, of his career as a clergyman in the Methodist and then in the Episcopal Church, and of Ms being forced to leave the ministry on account of his growing disbelief in the supernatural doctrines of re- ligion and his increasing disgust with the practices of church - members and men in holy orders. The experiences and incidents which are told in this volume under the veil of fictitious names exhibit many of the per- sons with whom Mr. Bray's labors brought him in contact in no very enviable light. The story, especially the part relating to the author's married life, reveals the joys and sorrows, hopes and fears, discouragements and triumphs of an affectionate, sensitive, and religious nature, which has been sadly torn by contact with the world. Bulletin No. 7 of the Iowa Agricultural Experiment Station contains accounts of ex- periments and observations on seven sub- jects. The chief article is on varieties of corn, and is illustrated with four plates. The other topics treated are the millets, sugar from sorghum, the codling moth, new Cyni- pidce, the hog-louse, and varieties of grapes. The Monthly Bulletin of the Iowa State Board of Health (Des Moines, 25 cents a year) is a decidedly practical and wide-awake document. Each number is made up of brief and timely articles on hygienic sub- jects, replies to questions, reports of mortal- ity, and of the appearance of contagious dis- eases within the State, etc. A Signal Corps meteorological report for each month is also included. A brief account of Massage and the Origi- nal Swedish Movements has been prepared for physicians and others interested by Kurre W. Ostrom (Blakiston, 75 cents). It de- scribes the operations of massage, with fig- ures, and the various passive movements be- longing to the Swedish system. Lists of 136 THE POPULAR SCIENCE MONTHLY. manipulations and movements suitable for a large number of diseases are given. In these applications Ling's and Mezger's systems have generally been followed. Some consid- erations in regard to the effects of exercise are included in the volume, and a caution against the untrained " rubbers " who form a large part of those who claim to be mas- seurs in America, or who use the name as a cloak for vice.

Jacob EnniSt — This able but retiring man was born in Essex County, N. J., in 1807. He came of sturdy Scotch-Irish stock on his fa- ther's side, and was of Dutch extraction (the Doremuses) on his mother's side. After grad- uating at Rutgers College, and when yet quite a young man, he connected himself with the Dutch Reformed Church, and was by that or- ganization sent to the islands of Java and Sumatra as a missionary, where he remained four years. Here his powers of observation and his love for the study of nature had an early development. Returning to his native country, he soon engaged in educational work, and was elected Professor of Natural Sciences in the National Military College of Bristol, Pa. Afterward he became principal and pro- prietor of the Scientific and Classical Insti- tute of Philadelphia, where he spent the best part of his life. He also occupied for some years the chair of Physical Sciences in the State Normal School at Shippenburg, Pa. In his career as an educator, he from the start laid great stress on the importance of the study of nature, and was indeed a bold and fearless innovator in this respect, anticipat- ing by perhaps a quarter of a century the recognition that scientific studies have sub- sequently had in all the highest institutions of learning. His life was quiet, simple, dig- nified, but laborious. He was a member of the chief scientific bodies both in this coun- try and abroad, and his contributions in the shape of addresses before learned societies, pamphlets, and articles in scientific periodi- cals were many and varied, always strikingly original, often profound, and sometimes pro- phetic. Among these contributions, chiefly on astronomical problems, "was one entitled The Two Great Works to be done on our Si- dereal Systems. In this publication two ques- tions are asked — First : Which way round does the great ring of the milky way revolve ? Second : In which direction must we look for the center of our sidereal systems, and how far is it distant? These two questions he attempted to answer himself in an unpub- lished work, upon which he expended all the time and thought that he could command during the latter days of his life. He con- sidered this the most important and certain- ly the most original and far-reaching of his works on astronomy, and it will no doubt be published in due time. In his book on The Origin of the Stars, published over twenty years ago, some of the most transcendental problems of physical astronomy were at- tacked and solved with a keen analysis, an abundance of facts, and a wealth of illus- tration worthy of a master of the science. Prof. Ennis's intellectual scope and sympa- thies were not narrow or one-sided ; he was familiar with the entire range of English and classical literature, and was an excellent lin- guist. His literary style was simple, direct, and lucid ; he had a great dislike for " big words," and always succeeded in making his ideas clear by the use of plain and untechnical language even when handling the most ab- struse problems. His habits and tastes were simple, his wants few, his disposition kindly and gentle, and the attitude of his mind was distinctly reverent. He was so quiet, mod- i 3 8 THE POPULAR SCIENCE MONTHLY. est, and unobtrusive that but few suspected the presence of a great thinker so near at home, and fewer still knew him personally. He died in Houston, Texas, January 12, 1890. The Late Henry James Clark. — A biogra- phy and bibliography of Henry James Clark has been published by the Massachusetts Agricultural College, in which he was the first professor. He was born in 1826, be- gan the study of botany under Asa Gray in 1850, and became a pupil and private assist- ant of Agassiz, who spoke of him in 1857 as "the most accurate observer in the coun- try." He was in succession adjunct Pro- fessor of Zoology in Harvard University; Professor of Botany, Zoology, and Geology in the Agricultural College of Pennsylvania ; Professor of Natural History in the Univer- sity of Kentucky; and Professor of Com- parative Anatomy and Veterinary Science in the Massachusetts Agricultural College; and he was a member, fellow, or correspond- ent of the principal American scientific so- cieties, including the Academy of Sciences when its membership was limited to fifty. He assisted Agassiz in the preparation of parts of the Contributions to the Natural History of the United States ; delivered lect- ures on histology and the Cambridge Muse- um of Comparative Zoology ; and delivered a course of lectures at the Lowell Institute on Mind in Nature ; or the Origin of Life, and the Mode of Development of Animals. He died on the first day of July, 1873, in the forty-eighth year of his age. The list of his scientific writings comprises twenty -seven titles, mos of which cover more than one article. Educational Valne of Manual Training. — The committee report of the National Council of Education on the Educational Value of Manual Training admits the rea- sonableness of substituting a system of man- ual training in special schools, in so far as it can be done, for the old system of appren- ticeship, but insists that the training ought not to be begun before the completion of the pupil's twelfth year, nor before he has had the statutory instruction prescribed by the state in the intellectual branches of school work. It admits that manual train- ing is an educative influence, and that, in so far as the schools teach the scientific prin- ciples that underlie the practical points of their work, they add intellectual education to physical education. The study of general scientific principles, according to Dr. William T. Harris's interpretation of the views of the report, would be educative in the first rank : they explain all machines and all natural phenomena in our present experience, and will explain those that we meet in the fu- ture. In the second rank are special appli- cations of science in the form of theories of special machines, as, for example, of the steam-engine. These theories explain all machines made in accordance with them ; they are very general, but not so general as the scientific theories of the forces involved. They are accordingly less educative. A third and least educative school exercise is the construction of a particular machine, when the theory is narrowed down to a special example. The laborer meets many new things in the work of constructing the ma- chine, but unhappily they are not educative, because they are contingent, and do not as- sist in explaining or constructing the next machine. Examined in these three grades of educative value, the purely manual work of the school belongs to the lowest grade, and furnishes the obscurest knowledge of principles covered up by a mass of non-es- sential circumstances. The committee, how- ever, lays stress on the importance of aes- thetic culture through drawing. It is cult- ure in taste that American workmen need, and not culture in skill, for our laborers are already ingenious and skillful and indus- trious. Drawing is the best means of ac- quiring familiarity with the conventional forms of beauty in ornament — forms that express the outlines of freedom and grace- fulness, and charm all peoples, even those who have not the skill to produce them; and make markets for the articles that bear them. Causes of Insanity. — The latest report of the British Commissioners of Lunacy gives tables showing the causes of insanity as verified by the medical officers of the institu- tions, in the cases of 136,478 patients who have been admitted into public and private asylums since 1887. The causes are classi- fied as " moral " and " physical." As might POPULAR MISCELLANY. »39 be expected, " intemperance in drink " heads the list of single causes, with 18,290 cases. Of "moral causes," "domestic trouble," " adverse circumstances," and " mental anxiety and worry, and overwork," are col- lectively held responsible for 25,897 cases. Of other moral causes, "religious excite- ment" is credited with 3,769 cases, "love affairs " with 2,224, and " fright and nerv- ous shock " with 1,953. Of physical causes, "sexual diseases" are credited with 3,447 cases, " overexertion " with 761, " sun- stroke " with 1,686, " accident or injury " with 4,199, " diseases of women " with 11,315, "old age" with 5,773, "privation and starvation " with 2,607, " fevers " with 880, "puberty" with 582, and "other bodi- ly diseases or disorders " with 14,719. Previous attacks had occurred in 22,703 cases. Hereditary influence was ascertained in 28,063, and congenital defect in 5,881. As between the sexes, 66,918 were of the male and 69,560 of the female sex. Rights on Other Men's Lands. — A paper by Mr. Hyde Clarke, on "The Rights of Property in Trees " on the land of another, relates to a curious custom of primeval times which still survives in some lands. The author first met it as a land judge in Asia Minor in 1862, when he was called upon to grant compensation for olive-trees belonging to one or more persons on the lands of others, and for honey - trees or hoards of wild honey in state or communal forests. Papers read by the Rev. Dr. Cod- ington gave information of the existence of a like system in Melanesia. It likewise prevails, according to Mr. Crocker, of the British North Borneo Company, in Borneo, in respect to the Icatapang, or honey-tree, and also in the case of caves containing edi- ble bird's-nests. Sir Spencer St. John also observes that in Borneo the land nominally belongs to the state or tribe, but the owner- ship is not a private property in land in our sense of the word. He had observed that certain of the tapang, on which the bees construct their nests, often belonged to special families, and were not touched by their neighbors. Sir Thomas Wade has found a similar right in China, where, when hill farms or gardens are leased, the tenant will pay the proprietor a yearly rent. All fir-trees or bamboos on the ground before it is let belong to the proprietors, and the ten- ant is "not free to appropriate them. If there were no such trees on the ground when it was let, and such trees were subsequently planted by the tenant, they would be at his disposal. Separate property in trees is also traceable in India, particularly in Chota Nagpore, where Mr. J. F. Hewitt has fre- quently found that fruit trees growing on land are owned by persons other than the owners or cultivators of the soil. The mhowa- trees, which are exceedingly valu- able, are frequently divided among the in- habitants of the villages near which they grow. This individual property in trees is not in Turkey confined to Asia Minor, but prevails as a general law in the empire. Miss Pauline Inby found it in Bosnia, and bought an interest of the kind in a certain estate. It seems also to have anciently existed in the British Islands, and is recog- nized in the Brehon records of Ireland. But there, and in most European countries, the vestiges of the separate rights have ceased to exist. Soaping Geysers. — It ha3 been often ob- served that throwing soap into the geysers of the Yellowstone Park will produce or hasten an outburst. The phenomenon has been investigated by Prof. Arnold Hague, of the United States Geological Survey, who finds that two conditions are essential to the production of an eruption in this way : first, the surface caldron or reservoir should hold but a small amount of water, exposing only a limited area to the atmosphere ; and, sec- ond, that the water should stand at or above the boiling-point of water for the altitude of the geyser basin above sea-level. The latter is the principal factor. Many of the geysers and hot springs present the singular phe- nomena of pools of water heated above the theoretical boiling-point, and, unless dis- turbed, frequently remain so for many days without exhibiting any signs of ebullition. Thermal waters in this condition may be made to boil by other artificial means that will dis- turb their equilibrium, as by casting sinter into them, and, in one instance at least, by a strong temporary gust of wind. If soap or lye is thrown into most of the small pools, a viscous fluid is formed ; and viscosity is, in 140 THE POPULAR SCIENCE MONTHLY. the opinion of the author, the principal cause in hastening geyser-action. It tends to cause the steam to be retained within the basin, and, when the temperature stands at or above the boiling-point, explosive liberation must follow. All alkaline solutions exhibit, by reason of this viscosity, a tendency to bump and boil irregularly. Viscosity in the hot springs must also tend to the formation of bubbles and foam when the steam rises to the surface, and this in turn aids to bring about the explosive action, followed by a relief of pressure, and thus to hasten the final and more powerful display. The prac- tice of casting in soap is regarded as detri- mental to the preservation of the geysers, and as a proper object of restriction. The Nature of Poisoned Arrows. — The word poison, as applied to the poisoned arrows used in the Solomon Islands, Santa Cruz, the Banks Islands, and the New Hebrides, should be understood, according to the Rev. Dr. R. H. Codington, in a peculiar sense. The practice of administering poison in food was com- mon among the natives, but it was doubtful whether what was used had much power of doing harm. The deadly effect was expected to follow from the incantations with which the poison was prepared. In the same way the deadly quality of the poisoned arrows was never thought by the natives to be due to poison in our sense of the word, though what was used might be, and was meant to be, injurious and active in inflaming the wound. It was the supernatural power that belonged to the human bone of which the arrow-head was made on which they chiefly relied, and with that the magical power of the incantations with which it was fastened to the shaft. The bone of any dead man will give efficacy in the native belief to the arrow, because any ghost may have power to work on the wounded man ; but the bone of one who was powerful when alive is more valued. In Lepers' Island, a young man, out of affection for his dead brother, took up his bones and made them into arrows. He carried these about him, and did not speak of himself as " I," but as " we two " — his brother and himself — and he was much feared; all the supernatural power of the dead brother was with the living. Although it is the human bone that gives the deadly quality to the arrow, the bone must be pre- pared with certain incantations which add supernatural power. The poison is an addi- tion to the power of the bone. The native did not much consider, if at all, the natural power to hurt, of either bone or poison. A dead man's bone made the wound, the power of the ghost was brought by incantation to the arrow, and therefore the wounded man would die. Euphorbia-juice is hot and inflaming; it is smeared on the bone with an incanta- tion which calls in the power of a dead man's ghost ; when the wound is given, the ghost will make it inflame. The cure of the wounded man is conducted on the same prin- ciple. If the arrow-head, or a part of it, can be recovered, it is kept in a damp place or on cool leaves ; the inflammation of the wound is little, or subsides. Shells are kept rattling over the house where the man lives, to keep off the hostile ghost. In the same way the enemy who has inflicted the wound, and his friends, will drink hot and burning juices, and chew irritating leaves ; pungent and bitter herbs will be burned to make an irritating smoke, and will be tied upon the bow that sent the arrow ; the arrow-head, if recovered, will be put into the fire. The bow will be kept near the fire, and its string kept taut and occasionally pulled, to bring on tension of the nerves and the spasms of tetanus. Prof. Victor Horsley has suggested that the value of the human bone tipping the arrow was first made evident by the employ- ment of a bone from a corpse recently dead, in the decomposing tissues of which the septicsemic virus would consequently be flour- ishing. The Mesozoie Atlantic Coast Region. — In his address before the Geological Section of the American Association, Prof. Charles E. "White, defining the Mesozoie formations of North America, said that the rocks of the Triassic age are found from Prince Edward Island to the Carolinas. They rest on for- mations, from the Archaean to the Carbon- iferous, inclusive. Verv few invertebrate fossils have been found in the Trias of the Atlantic coast region, and these are of little value for indicating the age of the strata that contained them. Intermediate between the Triassic beds and the undisputed Creta- ceous deposits of this region is a series of POPULAR MISCELLANY. 141 strata of littoral and estuary origin, to which the name Potomac formation has been ap- plied. These deposits are only a few hun- dred feet thick, and, though frequently cov- ered from sight, seem to be continuous from New Jersey to Mississippi. Invertebrate fos- sils are rare, but large collections of fos- sil plants have been found in the Potomac region. The best authorities recognize sev- eral of these fossils as Jurassic. Briefly, then, the Mesozoic of the Atlantic coast region consists of a probable representation of the Upper Trias of Europe, a possible one of the Upper Jura, a probable slight one of the Middle Cretaceous, and a practically certain representation of a large part of the Upper Cretaceous, with a hiatus between the latter and the Eocene. The speaker advo- cated a system of classification more suited to this country than the European one. The time has come when North American geolo- gists can and ought to hold a commanding position in this matter. Olives and their Oil. — The olive has been cultivated in the regions of the Medi- terranean coasts from time immemorial. Ol- ive-oil there takes the place of butter. Spain has about 3,000,000 acres in olives, Italy 2,250,000, and France about 330,000 acres. Forty-five varieties of the fruit are described. The tree occasionally grows to be sixty feet high, and twelve feet in circumference of trunk. The varieties differ in the nature of the wood, the foliage, and the quality and shape of the fruit. The fruit is mild, or sharp, or bitter ; and the oils differ like- wise ; so that a pure olive-oil may be unfit for purposes of food, and only fit for greas- ing machinery and making soap. The green, unripe olives, having had the bitter taste extracted with salt, are preserved in vinegar with spices. The ripe olives are gathered in the fall, when they are as large as common plums. They are of dark-green color, and the pit, now become a hard stone, contains a savory kernel. The flesh is spongy, and its little cells are filled with the mild oil, which runs out at the least pressure. The finest oil is the virgin oil which is made by col- lecting the freshly gathered olives in little heaps, and letting them press the oil out by their own weight. It is clear, and has a deli- cate, nutty taste, with little or no odor. When the fruits cease to give the oil by them- selves, they are pressed with small millstones, yielding an oil which is also clear and has a pleasant taste. The olives, still rich in oil, are next put in sacks, boiling water is poured over them, and they are pressed once more. The oil gained by this process is yellowish- green, and has a sharp taste and an unpleas- ant smell. At Marseilles the olive-oils are classed into manufacturing oils for burning, greasing machinery, and soap-making; re- fined oil ; oil from the pulp or husks, and table or edible oil. The last is superfine, fine, half fine, and ordinary. The table oil is refined by allowing it to run through lay- ers of thin sheets of wadding into tin perfo- rated boxes. The wadding absorbs all the thick particles, and leaves the oil clear and tasteless. The olive crop is variable and un- certain, and is seldom profitable more than once in six or eight years. Avogadro. — According to a sketch pub- lished by Prof. Hugo Schiff, of Florence, in the " Chemiker Zeitung," Amadeo Count Avogadro, son of the magistrate Filippo Vercellone, was born in Turin, August 9, 1776. He studied jurisprudence at the Tu- rin University, became Doctor of Laws on March 16, 1796, and then held a position under the Government till 1S06, when he began his scientific career. In physics he was self-taught, and obtained a subordinate position in the Collegio delle Provincie in Turin, which was then and still is a richly endowed department of the Turin Universi- ty. On November 7, 1809, he became Pro- fessor of Physics at the Gymnasium in Ver- celli. In 1820 he was elected Professor of Mathematical Physics at the Turin Univer- sity. Later this chair of instruction was abolished, and Avogadro resumed the prac- tice of law. He was, however, reinstated in his chair through the influence of Charles Albert, and remained at the university till 1850, when he retired on account of old age and ill health. He died at Turin, July 9, 1856, at the age of eighty years. Avogadro was but little known in Italy and unknown in foreign countries. He shared with Charles Gerhard, who died in the same year, August 19, 1856, the same fate. It was only after death that their great and important contri- butions to science found recognition. 142 THE POPULAR SCIENCE MONTHLY. Atmospheric Nitrogen as Food for Plants. — The results of experiments at the agricultural stations at Middletown and Mansfield, Conn., are in favor of the value of atmospheric nitrogen as a food for plants. The conclusions are deduced from them by Prof. Atwater that many, if not most, of the leguminous plants are able to and do ac- quire large quantities of nitrogen from the air during their period of growth ; and that there is some connection, not yet defined, between root -tubercles and the acquisition of this aliment. The cereals with which ex- periments have been completed have not manifested the same power, and they do not have such tubercles as are formed on the roots of the legumes. The addition of soil in- fusions did not seem necessary for the pro- duction of root-tubercles. The size and vigor of the plants, and their gain of nitrogen from the air, seemed to be proportional to the abun- dance of root-tubercles in the experiment. Losses of nitrogen sometimes occurred, but always in cases where there were no root-tu- bercles. The ability of legumes to gather nitrogen from the air helps to explain the usefulness of certain members of the family as renovating crops, and enforces the im- portance of using them to restore fertility to exhausted soils. Conversely, the loss of ni- trogen suffered by some other crops, such as oats, suggests a possible reason why they should appear to be " exhausting " crops. Coffee in Brazil.— The cultivation of cof- fee has been greatly extended in Brazil dur- ing recent years, chiefly in the southern provinces. The planting is done on freshly cleared ground after a single crop of Indian corn has been raised from it, either by sow- ing the seed directly or often by transplant- ing from slips grown in nursery rows. Dur- ing the earlier years corn, beans, and occa- sionally sugar-corn are grown between the rows. The coffee-plant usually begins to bear at the fourth year from the nursery, or the fifth or sixth year from the seed. The tree is supposed to reach its prime at ten years old, becomes practically sterile at twen- ty, and may by care be kept in bearing for forty years. The extremes of the flowering season are from August to January. The berry begins to form in November, and to ripen in April or May, when the harvesting begins. This is done by hand, and gener- ally very carelessly. The berries are washed, dried, and put through various processes of cleaning for the market ; what is called " washed " coffee is put through a different process, in which much of the treatment is given under water. Objeet-Stndies in Botany. — Prof. Bessey some time ago urged teachers of botany to give a more intelligent direction to the col- lections which their pupils will make during the season of study. The usual course is to gather a surplus of the showy flowers which are the most easily studied, and neglect the others, of which less is known. The teacher should take special pains to point out the features of interest in the funguses, etc., which the student may bring in. Let him direct attention to the pores, on the walls of which the spores are developed — to the closely interwoven threads of the body of the fungus. When a spotted strawberry- leaf is brought in, let him tell something, if it be but little, about the cause of the spots ; and let the pupil be taught to look for similar spots on other plants, and to study them. Do so with lichens, with pond-scums, with green slimes, with mosses, with liver- worts — in fact, with whatever is brought in by the sharp-eyed young collector. " He must be a poor teacher indeed who can not suggest something to his pupil about a toad- stool or a puff-ball. It is not necessary to know the species or even the genus to which a plant has been assigned in order to be able to make valuable suggestions to one's pu- pils." Contributions to the Geology of Staten Island. — Dr. N. L. Britton has reported to the Natural Science Association of Staten Island concerning observations that lead him to consider that the serpentine and talcose rocks forming the main ridge of the island were derived from magnesian limestone and hornblende or tremolite strata. The rocks were doubtless originally deposited in a con- formable sequence, but the serpentines were left on top in the folding of the strata. The hypothesis of a southwestward extension of the crystalline rocks across New Jersey has been confirmed in a well-boring at Perth Am- bov. Considerable additions to the fossil NOTES. H3 flora have been obtained by Mr. Hallick from the ferruginous sandstone on the shore at Tottenville. The occurrence of copper, de- rived from the decomposition of pyrites, in the limonite ore beds at Todt Hill is men- tioned. Several well-defined nearly driftless areas north and west of the terminal mo- raine illustrate an interesting feature of gla- ciation. NOTES. Prof. D. S. Martin's Geological Map of New York City and its Environs is the only map giving in detail the geology of the en- tire region (fifty-five by sixty-eight miles) surrounding the metropolis ; it is compiled with great care from separate sources, some of which are not easily accessible, and some are unpublished ; it exhibits the relations of many geological systems and series east of the Alleghanies ; and shows striking features connected with the Glacial age, the terminal moraine, and the ancient (now submerged) channel of the Hudson River. A pamphlet of explanations accompanies every copy. A few copies of the second edition of the map still reman for disposal at ten dollars each. No more are likely to be published.

Orcutt remarks, in the West American Scientist, on the prominence of the great variety in rock-lichens in producing a pleasing effect in the scenery of Lower Cali- fornia. Red, yellow, gray, and white are the prevailing colors, and the whole side of a cliff is often covered by lichens of the same tint. Quartz, however, is not a favorite rock with the lichens, and consequently is seldom con- cealed. The lichens frequently imitate, in coloring, the natural hue of the rocks on which they are found. A book by Mr. George F. Kunz, the dis- tinguished mineralogical expert of the house of Tiffany & Co., on the Gems and Precious Stones of North America, is announced for publication by the Scientific Publishing Company, New York. It will be a popular description of the occurrence, value, history, and archaeology of precious stones in Amer- ica, and of the collections in which they ex- ist, with a chapter on pearls. The several species and varieties are described system- atically. The work will be sold at ten dol- lars a copy. Mr. John Griffttt, of Smyrna, has re- ported favorably on the results of a sea- son's experiments in rearing silk-worms on mulberry-trees, under muslin screens, in the open air, using the regenerated Bournabat graine. They show that the regeneration was thorough and complete, enabling the worms to endure the low temperature of 45° F., with storm and wet for ten consecutive days. The proportion of Ratine or satin-like cocoons was extraordinary — fifty to two hundred and ninety-four in all. A somewhat similar trial made in India some years ago was success- ful experimentally but not financially. In this case the worms, under calico screens, ate along the hedge at their will, new relays taking the place of the old ones as the parts of the hedge over which thev had eaten re- covered their leaves. River water was substituted for spring water in one of the quarters of Paris sev- eral times last summer. In every instance, according to the " Semaine Medicale," an in- crease of typhoid fever was observed. The quantity of spring water brought to Paris being insufficient for the demand, the Coun- cil of Public Hygiene and Health has deter- mined to expedite the labors for the new supply from springs recently bought by the city, and to insist that the use of the present spring waters be limited to food purposes.

M. de Malarce recently informed the French Academy of Sciences that the use of the metric system had in 1887 become com- pulsory in countries having an aggregate pop- ulation of 302,000,000, being an increase of 53,000,000 persons obliged to use it in ten years ; use was optional in countries having nearly 97,000,000 inhabitants ; and was le- gally admitted and partially applied in coun- tries having an aggregate population of 395,- 000,000. The systems of Japan, China, and Mexico are decimal but not metric. Hence the metric system is legally recognized by 794,000,000 people and decimal systems by about 474,000,000 others. By the Hungarian trade law of 1884, every commune in which there are fifty or more apprentices must provide for their ed- ucation, and afford special courses of in- struction. The apprentice schools in Buda- Pesth contain a preparatory class, provide a course of three years, and are chiefly de- signed to educate apprentices for the higher trade schools. Each district of the town must have at least one apprentice school. No class is to have more than fifty or at most sixty pupils. Deserving pupils are pro- moted at the end of each year. In the oth- er towns and counties of the kingdom there are 229 apprentice schools, with 1,237 teach- ers and 38,081 pupils.

A scheme of the French Government to encourage the intermarriage of life-convicts in New Caledonia with life-convicts import- ed from the prisons at home is pronounced mischievous by the " Lancet." The purpose is to build up family relations in the inter- est of morality ; but British experience is to the effect that such alliances lead to the multiplication of criminals, and that the real check to crime lies in breaking up and iso- lating the criminal class. Testimony gleaned by M. Louis Barron from the journals of New Caledonia points in the same direction, and forms an instructive commentary on the law of heredity as deduced by Darwin. The French fishermen are troubled by the depredations of porpoises, for which they have not succeeded in finding a remedy. An attempt was made to catch them in seine nets, but they jumped out of the snares. They were scared away by guns and torpe- does, but the fish were frightened and dis- appeared with them. They are too numer- ous to be shot one by one in an effective manner. The only thing to be done seems to be for the fishermen to unite and drive them away in crowds ; but this will have to be often repeated. Insurance and payment of damages by the Government are the last measures of relief suggested ; but they, too, are expensive to somebody. Vanilla is produced from a species of orchid that attaches itself to walls, trees, and other suitable objects. The plant has a long, fleshy stem, and the leaves are alter- nate, oval, and lanceolate. The flower is of a greenish-white color, and forms axillary spikes. The fruit is a pod, measuring when full grown some ten or twelve inches in length and about half an inch in diameter. The quality of the pod can be determined by the presence or non-presence of a crystalline efflorescence called givre, and by its dark chocolate-brown color. The fragrant givre is vanillin, C 8 H 8 3 . The pods also contain va- nillic acid, oily matter, soft resin, sugar, gum, and oxalate of lime. A striking example of degeneration in growth is exhibited by the scale that attacks greenhouse and other plants. According to Mr. Bernard Thomas, in "Science Gossip," it is a degenerated female which lives upon the sap of the plant, continuing to increase in size and reproduce its young. These may be found underneath it as minute red bod- ies, just visible to the naked eye, and at this time of their life comparatively active creat- ures ; but they soon settle down and begin to degenerate. Their eyes become indis- tinct, and finally, with their antenna; and legs, shrivel away, the body loses its thick- ness, and they appear as if without life. Totems are defined by Mr. J. G. Fraser as " a class of material objects which a sav- age regards with superstitious respect, be- lieving that there exists between him and every member of the class an intimate and altogether special relation." They are tribal emblems, family symbols, signals of nation- ality, expressions of religion, bonds of un- ion, and regulators of marriage-laws and of the social institutions. The system of to- tems exists among most primitive peoples, and in similar forms with the North Ameri- can Indians, Australians, South Africans, Arabs, hill tribes of India, Polynesians, and many other peoples. Among a tribe in Co- lombia, where descent is in the female line, it goes so far that if a man happens to cut himself with his own knife, to fall off from his own horse, or to hurt himself in any way, his mother's clan demand blood-money from him for injuring one of their totems. OBITUARY NOTES. Prof. Van Quenstedt, of Tubingen, one of the most famous of German paleontolo- gists, died December 21st, at an advanced age. He was the author of a work on the Jura, and of a Handbook of Petrefacten- kunde, or the science of petrifactions. He had an especially profound knowledge of the Lias of Wiirtemberg and its fossils. M. Ch. Fievez, assistant in the spectro- scopic department of the Royal Observatory of Brussels, died February 2d, aged forty-five years. He studied first for the military pro- fession, but was invited to the observatory by M. Houzeau, and entered it after studying under Janssen at Meudon. His most impor- tant work was the construction of a chart of the solar spectrum on a larger scale than that of Angstrom. He made a detailed study of the spectrum of carbon, and experi- ments on the behavior of spectral lines un- der the influence of magnetism and of changes of temperature. Dr. C. C. Parry, a distinguished Ameri- can botanist, recently died at Davenport, Iowa, aged sixty-seven years. He made val- uable collections of plants, and was an au- thority in the classification of the North American flora. He was for several years a botanist in the* Agricultural Department in Washington. Mount Parry, near Denver, was named after him. Prof. Richard Owen, geologist, died from accidental poisoning at his home in New Har- mony, Ind., March 24th. He was a son of the Scotch philanthropist, Robert Owen, and was born in Scotland, January 6, 1810. Having been schooled in Europe and come to the United States, he studied civil engineering in Kentucky, was a Professor of Geology there, served in the United States Survey, was a captain in the Mexican War, was State Ge- ologist for Indiana, professor in Indiana State University, and lieutenant-colonel and colonel in Indiana volunteer regiments. THEODORE SCHWANN. THE POPULAR SCIENCE MONTHLY. JUNE, 1890. NEW CHAPTERS IN THE WARFARE OF SCIENCE. VIII. THE ANTIQUITY OF MAN AND EGYPTOLOGY. By ANDREW DICKSON WHITE, LL. D., L.H.D., EX-PRESIDENT OF CORNELL UNIVERSITY. IN the great ranges of investigation which, bear most directly upon the origin of man, there are two in which Science within the last few years has gained final victories. The significance of these in changing, and ultimately in re- versing, one of the greatest currents of theological thought, can hardly be overestimated ; not even the tide set in motion by Cusa, Copernicus, and Galileo was so powerful to bring in a new epoch of belief. The first of these conquests relates to the antiquity of man on the earth. The fathers of the early Christian Church, receiving all parts of our sacred books as equally inspired, laid little, if any, less stress on the myths, legends, genealogies, and tribal, family, and personal traditions contained in the Old Testament, than upon the most lofty poems, the most instructive apologues, and the most powerful utterances of prophets, psalmists, and apostles. As to the life of man upon our planet, by bringing together indi- cations of elapsing time in the various books of the Bible, early Christian commentators arrived at conclusions varying some- what, but in the main agreeing. Some, like Origen, Eusebius, Lactantius, Clement of Alexandria, and the great fathers gener- ally of the first three centuries, dwelling especially upon the Sep- tuagint version of the Scriptures, thought that man's creation took place about six thousand years before the Christian era. Strong confirmation of this view was found in a simple piece of VOL. XXXYII. — 11 i 4 6 THE POPULAR SCIENCE MONTHLY. purely theological reasoning : for, just as the seven candlesticks of the Apocalypse were long held to prove the existence of seven planets revolving about the earth, so it was felt that the six days of creation prefigured six thousand years during which the earth in its first form was to endure ; and that, as the first Adam came on the sixth day, Christ, the second Adam, had come at the sixth millennial period. Theophilus, Bishop of Antioch, in the second century, clinched this argument with the text, " One day is with the Lord as a thousand years"; hence the view of the early Church, that the world was then in its last period, and that the seventh day — the great millennium — would arrive about the year 1000 of our era. What striking consequences this belief finally produced all scholars of mediaeval history know well. On the other hand, Eusebius and St. Jerome, dwelling more especially upon the Hebrew text, which we are brought up to re- vere, thought that man's origin took place at a somewhat shorter period before the Christian era ; and St. Jerome's overwhelming authority made this the dominant view throughout western Eu- rope during fifteen centuries. The simplicity of these great fathers as regards chronology is especially reflected from the tables of Eusebius. In these, Moses, Joshua, and Bacchus — Deborah, Orpheus, and the Amazons — Abimelech, the Sphinx, and CEdipus, appear together as person- ages equally real, and their positions in chronology equally ascer- tained. At times great bitterness was aroused between those holding the longer and the shorter chronology, but, after all, the difference between them, as we now see, was trivial ; and it may be broadly stated that in the early Church, " always, and everywhere, and by all," it was held as certain, upon the absolute warrant of Script- ure, that man was created from four to six thousand years before the Christian era. To doubt this, and even much less than this, was to risk dam- nation. St. Augustine insisted that belief in the antipodes and in the longer duration of the earth than six thousand years were deadly heresies, equally hostile to Scripture. Philastrius, the friend of St. Ambrose and St. Augustine, whose fearful catalogue of heresies served as a guide to intolerance throughout the middle ages, condemned with the same holy horror those who expressed doubt as to the orthodox number of years since the beginning of the world, and those who doubted an earthquake to be the literal voice of an angry God, or who questioned the plu- rality of the heavens, or who gainsaid the statement that God brings out the stars from His treasures and hangs them up in the solid firmament above the earth every night. About the beginning of the seventh century, Isidore of Seville, NEW CHAPTERS IN THE WARFARE OF SCIENCE. i 47 the great theologian of his time, took up the subject. He accepted the dominant view, not only of Hebrew but of all other chro- nology, without anything like real criticism ; the childlike faith and simplicity of his system may be* imagined from his summa- ries which follow. He tells us : " Joseph lived one hundred and five years. Greece began to cultivate grain. " The Jews were in slavery in Egypt one hundred and forty- four years. Atlas discovered astrology. "Joshua ruled for twenty-seven years. Ericthonius yoked horses together. " Othniel, forty years. Cadmus introduced letters into Greece. " Deborah, forty years. Apollo discovered the art of medicine and invented the cithara. " Gideon, forty years. Mercury invented the lyre and gave it to Orpheus." Reasoning in this general way, Isidore kept well under the longer date; and the great theological authority of southern Europe having thus spoken, the question was virtually at rest throughout Christendom for nearly a hundred years. Early in the eighth century the Venerable Bede, the great theological authority of the North, took up the problem. Dwell- ing especially upon the received Hebrew text of the Old Testa- ment, he soon entangled himself in very serious difficulties ; but, in spite of the great fathers of the first three centuries, he reduced the antiquity of man on the earth by nearly a thousand years, and, in spite of mutterings against him as coming dangerously near a limit which made the theological argument from six days to six ages look doubtful, his authority had great weight, and did much to fix western Europe in its allegiance to the general system laid down by Eusebius and Jerome. In the twelfth century this belief was re-enforced by a tide of thought from a very different quarter. Rabbi Moses Maimonides and other Jewish scholars, by careful study of the Hebrew text, arrived at conclusions diminishing the antiquity of man still fur- ther, and thus gave strength to the shorter chronology throughout the middle ages : it was incorporated into the sacred science of Christianity; and Vincent de Beauvais, in his great Speculum Historiale, forming part of that still more enormous work which sums up all the knowledge possessed by the ages of faith, placed the creation of man at about four thousand years before our era.* * For the date of man's creation as given by leading chronologists in various branches of the Church, see L'Art de Verifier les Dates, Paris, 1819, vol. i, pp. 27 et seq. In this edition there are sundry typographical errors ; compare with Wallace, True Age of the World, London, 1844. As to preference for the longer computation by the fathers of the Church, see Clinton, Fasti Hellenici, vol. ii, p. 291. For the sacred significance of the six days of i 4 8 THE POPULAR SCIENCE MONTHLY. At the Reformation this view was not disturbed. The same manner of accepting the sacred text which led Luther, Melanch- thon, and the great Protestant leaders generally, to oppose the Copernican theory, fixed them firmly in this biblical chronology ; the key-note was sounded for them by Luther when he said, " We know, on the authority of Moses, that longer ago than six thousand years the world did not exist." Melanchthon, more exact, fixed the creation of man at 3963 b. c. But the great Christian scholars continued the old endeavor to make the time of man's origin more precise ; there seems to have been a sort of fascination in the subject which developed a long array of chronologists, all weighing the minutest indications in our sacred books, until the Protestant divine, De Vignolles, who had given forty years to the study of biblical chronology, de- clared that he had gathered no less than two hundred computa- tions based upon Scripture, and no two alike. As to the Roman Church, about 1580 there was published, by authority of Pope Gregory XIII, the Roman Martyrology, and this, both as originally published and as revised in 1640 under Pope Urban VIII, declared that the creation of man took place 5199 years before Christ. But of all who gave themselves up to these chronological studies, the man who exerted the most powerful influence upon the dominant nations of Christendom was Archbishop Usher. In 1650 he published his Annals of the Ancient and New Testaments, and it at once became the greatest authority for all English-speak- ing peoples. Usher was a man of deep and wide theological learning, powerful in controversy; and his careful conclusion, after years of the most profound study of the Hebrew Scriptures, was, that man was created 4004 years before the Christian era. His verdict was widely received as final ; his dates were inserted in the margins of the authorized version of the English Bible, and were soon practically regarded as equally inspired with the sacred text itself ; to question them seriously was to risk prefer- ment in the Church and reputation in the world at large. The same adhesion to the Hebrew Scriptures which had influ- enced Usher, brought leading men of the older Church to the same view ; men who would have burned each other at the stake for creation in ascertaining the antiquity of man, see especially Eicken, Geschichte der mittelalterlichen Weltanschauung ; also Wallace, True Age of the World, pp. 2,3. For the views of St. Augustine, see Topinard, Anthropologic, citing the De Civ. Dei., lib. xvi, c. viii, lib. xii, c. x. For the views of Philastrius, see the De Haeresibus, c. 102, 112, et passim, in Migne. For Eusebius's simple credulity, see the tables in Palmer's Egyptian Chronicles, vol. ii, pp. 828, 829.

NEW CHAPTERS IN THE WARFARE OF SCIENCE. 149 their differences on other points, agreed on this : Melanchthon and Tostatus, Lightfoot and Jansen, Salmeron and Scaliger, Petavius and Kepler, inquisitors and reformers,- Jesuits and Jansenists, priests and rabbis, stood together in the belief that the creation of man was proved by Scripture to have taken place between 3900 and 4004 years before Christ. In spite of the severe pressure of this line of authorities, ex- tending from St. Jerome and Eusebius to Usher and Petavius, all in favor of this scriptural chronology, even devoted Christian scholars, had sometimes felt obliged to revolt. The first great source of difficulty was increased knowledge regarding the Egyp- tian monuments. As far back as the last years of the sixteenth century, Joseph Scaliger had done what he could to lay the foundations of a more scientific treatment of chronology, insist- ing especially that the historical indications in Persia, in Babylon, and, above all, in Egypt, should be brought to bear on the ques- tion. More than that, he had the boldness to urge that the chronological indications of the Hebrew Scriptures should be fully and critically discussed in the light of Egyptian and other records, without any undue bias from theological considerations. His idea may well be called inspired, yet it had little effect as re- gards a true view of the antiquity of man, even upon himself, for the theological bias prevailed above all his reasonings, even in his own mind. Well does a brilliant modern writer declare that, " among the multitude of strong men in modern times abdicating their reason at the command of their prejudices, Joseph Scaliger is perhaps the most striking example." Early in the following century Sir Walter Raleigh, in his History of the World (1603-1616), pointed out the danger of ad- hering to the old system. He, too, foresaw one of the results of modern investigation, stating it in these words, which have the ring of prophetic inspiration : " For in Abraham's time all the then known parts of the world were developed. . . . Egypt had many magnificent cities, . . . and these not built with sticks, but of hewn stone, . . . which magnificence needed a parent of more antiquity than these other men have supposed." In view of these considerations, Raleigh followed the chronology of the Septuagint version, which enabled him to give to the human race a few more years than were usually allowed. About the middle of the seventeenth century Isaac Vossius, one of the most eminent scholars of Christendom, attempted to bring the prevailing belief into closer accordance with ascertained facts, but save by a chosen few his efforts were rejected. In some parts of Europe a man was by no means safe from bodily harm in holding new views on chronology. As an example of the ex- treme pressure exerted by the old theological system at times i 5 o THE POPULAR SCIENCE MONTHLY. upon honest scholars, we may take the case of La Peyrere, who, about the middle of the seventeenth century, put forth his book on the Pre-Adamites — an attempt to reconcile sundry well-known difficulties in Scripture by claiming that man existed on earth be- fore the time of Adam. He was taken in hand at once; great theologians rushed forward to attack him from all parts of Europe ; within fifty years thirty-six different refutations of his arguments had appeared ; the Parliament of Paris burned the book, and the Grand Yicar of the archdiocese of Mechlin threw him into prison and kept him there until he was forced, not only to retract his statements, but to abjure his Protestantism. But, in spite of warnings like this, we see the new idea crop- ping out in various parts of Europe. In 1672 Sir John Marsham published a work in which he showed himself bold and honest. After describing the heathen sources of Oriental history, he turns to the Christian writers, and, having used the history of Egypt to show that the great Church authorities were not exact, he ends one important argument with the following words : " Thus the most interesting antiquities of Egypt have been involved in the deepest obscurity by the very interpreters of her chronology, who have jumbled everything up {qui omnia susque deque permiscue- runt), so as to make them match with their own reckonings of Hebrew chronology: truly a very bad example, and quite un- worthy of religious writers." This sturdy protest of Sir John against the dominant system and against the " jumbling " by which Eusebius had endeavored to cut down ancient chronology within safe and sound orthodox limits, had little effect. Though eminent chronologists of the eighteenth century, like Jackson, Hales, and Drummond, gave forth multitudes of ponderous volumes pleading for a period somewhat longer than that generally allowed, and insisting that the received Hebrew text was grossly vitiated as regards chronol- ogy, even this poor favor was refused them ; the great mass of believers found it more comfortable to hold fast the faith com- mitted to them by Usher, and it remained settled that man was created about four thousand years before our era. This tide of theological reasoning rolled on through the eight- eenth century, swollen by the biblical researches of leading com- mentators, Catholic and Protestant, until it came in great majesty and force into our own nineteenth century ; and it was well re- ceived. At the very beginning of our century it gained new strength from various great men in the Church, among whom may be especially named Dr. Adam Clarke, who declared that," to preclude the possibility of a mistake, the unerring Spirit of God directed Moses in the selection of his facts and the ascertaining of his dates." NEW CHAPTERS IN THE WARFARE OF SCIENCE. 151 All opposition to the received view seemed broken down ; and as late as 1835, indeed as late as 1850, came an announcement in the work of one of the most eminent Egyptologists, Sir J. G. Wilkinson, to the effect that he had modified the results he had obtained from Egyptian monuments, in order that his chronology might not interfere with the received date of the Deluge of Noah.* But all investigators were not so docile as Wilkinson, and there soon came a new train of scientific thought which rapidly undermined all this theological chronology. Not to speak of other noted men, we have early in the present century Young, Champollion, and Rosellini, beginning a new epoch in the study of the Egyptian monuments. Nothing could be more cautious than their procedure, but the evidence was soon overwhelming in favor of a vastly longer existence of man in the Nile Valley than could be made to agree with even the longest duration then allowed by theologians. First of all, in spite of all the suppleness of men like Wilkin- son, it became evident that, whatever system of scriptural chro- nology was adopted, Egypt was the seat of a flourishing civiliza- tion at a period before the "Flood of Noah," and that no such flood had ever interrupted it. This was bad, but worse remained behind : it was soon clear that the civilization of Egypt began earlier than the time assigned for the creation of man, even ac- cording to the most liberal of the sacred chronologists. As time went on, this became more and more evident : the long duration assigned to human civilization in the fragments of Manetho, the Egyptian scribe at Thebes in the third century b. c, was discovered to be more accordant with truth than the chronol- ogies of the great theologians ; and, as the present century has gone on, scientific results have been reached absolutely fatal to the chronological view based by the universal Church upon Script- ure for nearly two thousand years. * For Lightfoot, see his Prolegomena relating to the age of the world at the birth of Christ; see also in the edition of his works, London, 1822, vol. iv, pp. 64, 112.

As is well known, the first of the Egyptian kings of whom mention is made upon the monuments of the Nile Valley is Mena, or Menes. Manetho had given a statement, according to which Mena must have lived nearly six thousand years before the Chris- tian era ; this was looked upon for a long time as utterly inad- missible, since it was so clearly at variance with the chronology of our own sacred books ; but, as time went on, large fragments of the original work of Manetho were more carefully studied and distinguished from corrupt transcriptions, the lists of kings at Karnak, Sacquarak, and the two temples at Abydos were brought to light, and the lists of court architects were discovered. Among all these monuments the scholar who visits Egypt is most im- pressed by the sculptured tablets giving the lists of kings. Each shows the monarch of the period doing homage to the long line of his ancestors. Each of these sculptured monarchs has near him a tablet bearing his name. That great care was always taken to keep these imposing records correct is certain ; the loyalty of sub- jects, the devotion of priests, and the family pride of kings were all combined in this, and how effective this care was is seen in the fact that kings now known to be usurpers are carefully omitted. The lists of court architects, extending over the pe- riod from Seti to Darius, throw a flood of light over the other records. Comparing, then, all these sources, and applying an average from the lengths of the long series of well-known reigns to the reigns preceding, the most careful and cautious scholars have satisfied themselves that the original fragments of Manetho rep- resent the work of a man honest and well informed, and, after making all allowances for discrepancies and the overlapping of reigns, it has become clear that the period known as the reign of Mena must be fixed at about five thousand years B. c. In this the three great Egyptologists of our time concur ; Mariette, the emi- nent French authority, puts the date at 5004 B. c, and with this the foremost English authority, Sayce, agrees ; Brugsch, the lead- ing German authority, puts it at about 4500 B. c. We have it, then, as the result of a century of work by the most acute and trained Egyptologists, and with the inscriptions upon the temples and papyri before them, both of which are now read with as much facility as many mediaeval manuscripts, that the reign of Mena must be placed close upon seven thousand years ago. But the significance of this conclusion can not be fully under- stood until we bring into connection with it some other facts re- vealed by the Egyptian monuments. The first of these is that which struck Sir Walter Raleigh — that, even in the time of the first dynasties in the Nile Valley, a high civilization had already been developed. Take, first, man NEW CHAPTERS IN THE WARFARE OF SCIENCE. 153 himself : we find sculptured upou the early monuments types of the various races — Egyptians, Israelites, negroes, and Libyans — as clearly distinguishable in these paintings and sculptures of from four to six thousand years ago as the same types are at the ■present day. No one can look at these sculptures upon the Egyp- tian monuments, or even the f ac-similes of them, as given by Lep- sius or Prisse d'Avennes, without being convinced that they indicate, even at that remote period, a difference of races so great that long previous ages must have been required to produce it. Take, next, the social condition of Egypt revealed in these early monuments of art : they force us to the same conclusion. Those earliest monuments show that a very complex society had even then been developed. We not only have a separation be- tween the priestly and military orders, but agriculturists, manu- facturers, and traders, with a whole series of subdivisions in each of these classes. The early tombs show us sculptured and painted representations of a daily life which even then had been developed into a vast wealth and variety of grades, forms, and usages. Take, next, the political and military condition : one fact out of many reveals a policy which must have been the result of long experience. Just as now, at the end of the nineteenth century, the British Government, having found that they can not rely upon the native Egyptians for the protection of the country, are drilling the negroes from the interior of Africa as soldiers, so the celebrated inscription of Prince Una, as far back as the sixth dynasty, speaks of the Maksi or negroes levied and drilled by tens of thousands for the Egyptian army. Take, next, engineering : here we find very early operations in the way of canals, dikes, and great public edifices, so bold in con- ception and thorough in execution as to fill our greatest engineers of these days with astonishment. The quarrying, conveyance, cutting, jointing, and polishing of the enormous blocks in the interior of the Great Pyramid alone are the marvel of the fore- most stone-workers of our century. As regards architecture, we find not only the pyramids, which date from the very earliest period of Egyptian history, and which are to this hour the wonder of the world for size, for boldness, for exactness, and for skillful contrivance, but also the temples with long ranges of colossal columns wrought in polished granite, with wonderful beauty of ornamentation, with architraves and roofs vast in size and exquisite in adjustment, which by their propor- tions tax the imagination, and lead the beholder to ask whether all this can be real. As to sculpture, we have not only the great Sphinx of Gizeh, so wonderful by its boldness and plastic character, dating from i 5 4 THE POPULAR SCIENCE MONTHLY. the very first period of Egyptian history, but we have ranges of sphinxes, heroic statues, and bas-reliefs, showing that even in the early ages this branch of art had reached an amazing develop- ment. As regards the perfection of these, Lubke, the most eminent German authority on plastic art, referring to the early works in the tombs about Memphis, declares that, " as monuments of the period of the fourth dynasty, they are an evidence of the high perfection to which the sculpture of the Egyptians had attained." Brugsch declares that " every artistic production of those early days, whether picture, writing, or sculpture, bears the stamp of the highest perfection in art." Maspero, the most eminent French authority in this field, while expressing his belief that the Sphinx was sculptured even before the time of Mena, declares that " the art which conceived and carved this prodigious statue was a finished art, an art which had attained self-mastery and was sure of its effects " ; and Sir James Fergusson, the highest English au- thority, declares, " We are startled to find Egyptian art nearly as perfect in the oldest periods as in any of the later." The evidence as to the high development of Egyptian sculpture in the earlier dynasties becomes every day more overwhelming. What exquisite genius the early Egyptian sculptors showed in their lesser statues is known to those who have seen those most precious specimens in the Boulak Museum at Cairo, which were wrought before the conventional type was adopted in obedience to religious considerations. Take, next, decorative and especially ceramic art : as early as the fourth and fifth dynasties we have vases, cups, and other ves- sels showing exquisite beauty of outline and a general sense of form equal to Etruscan and Grecian work of the best periods. Take, next, astronomy : to say nothing of the other evidences of a long development of thought in this field, we may go back to the very earliest period of Egyptian civilization, and we find that the four sides of the Great Pyramid are adjusted to the cardinal points with the utmost precision. " The day of the equinox can be taken by observing the sun set across the face of the pyramid, and the neighboring Arabs adjust their astronomical dates by its shadow." The same view is confirmed by philologists. To use words of Max Diincker : " The oldest monuments of Egypt, and they are the oldest, monuments in the world, exhibit the Egyptian in possession of the art of writing." It is found also by the inscriptions of the early dynasties that the Egyptian language had even at. that early time been developed in all essential particulars to the highest point it ever attained. What long periods it must have required for such a development every scholar in philology can imagine. NEW CHAPTERS IN THE WARFARE OF SCIENCE. 155 As regards medical science, we have the Berlin papyrus, which, although of a later period, refers with careful specification to a medical literature of the first dynasty. So, too, as regards archaeology : the earliest known inscrip- tions point to still earlier events and buildings, indicating a long sequence of previous events. * And, finally, as to all that pertains to the history of civiliza- tion, no man of fair and open mind can go into the museums of Boulak or the Louvre or the British Museum and look at the monuments of those earlier dynasties without seeing in them the results of a development in art, science, laws, customs, and lan- guage, which must have required a vast period before the time of Mena for their development. And this conclusion is forced upon us all the more invincibly when we consider the slow growth of ideas in the earlier stages of civilization as compared with the later — a slowness of growth which has kept the natives in many parts of the world in that earliest civilization to this hour. To this we must add the fact that Egyptian civilization was espe- cially immobile; its development into castes is but one among many evidences that it was the very opposite of a civilization developed rapidly. As to the length of the period before the time of Mena, there is, of course, nothing exact. Manetho gives lists of great personages before that first dynasty extending over twenty-four thousand years. Bunsen, one of the most learned of Christian scholars, de- clares that not less than ten thousand years were necessary for the development of civilization up to the point where we find it in Mena's time. No one can claim precision for either of these state- ments, but they are valuable as showing the impression of vast antiquity made upon the most competent judges by the careful study of those remains. No unbiased judge can doubt that an immensely long period of years must have been required for the development of civilization up to the state in which we there find it. The investigations in the bed of the Nile confirm these views. That some unwarranted conclusions have at times been an- nounced is true ; but the fact remains that again and again rude pottery and other evidences of early stages of civilization have been found in borings at places so distant from each other, and at depths so great, that for such a range of concurring facts, consid- ered in connection with the rate of earthy deposit by the Nile, there is no adequate explanation save the existence of man in that valley thousands on thousands of years before the longest time admitted by our sacred chronologists. Nor have these investigations been of a careless character. Be- tween the years 1851 and 1854, Mr. Horner, an extremely cautious i 5 6 THE POPULAR SCIENCE MONTHLY. English, geologist, sank ninety-six shafts in f our rows at intervals of eight English miles, at right' angles to the Nile, in the neigh- borhood of Memphis. From these pottery was brought up from various depths, and beneath the statue of Rameses II at Mem- phis at a depth of thirty-nine feet. At the rate of the Nile de- posit a careful estimate has declared this to indicate a period of over eleven thousand years. As eminent a German authority in geography as Peschel characterizes objections to such deductions as groundless. However this may be, the general results of these investigations, taken in connection with the other results of re- search, are most convincing. And, finally, as if to make assurance doubly sure, a series of archaeologists of the highest standing, French, German, English, and American, have within the past twenty years discovered relics of a savage period, of vastly earlier date than the time of Mena, prevailing throughout Egypt. These relics have been discovered in various parts of the country, from Cairo to Luxor, in great numbers. They are the same sort of prehistoric implements which prove to us the early existence of man in so many other parts of the world at a geological period so remote that the figures given by our sacred chronologists are but trivial. The last and most convincing of these discoveries, that of flint implements in the drift, far down below the tombs of early kings at Thebes, will be referred to later. What such discoveries prove, we shall con- sider in the next chapter.* * As to Manetho, see for a very full account of his relations to other chronologists, Palmer, " Egyptian Chronicles," vol. i, chap. ii.

HANFORD HENDERSON, PROFESSOR OF PHYSICS AND CHEMISTRY IN THE PHILADELPHIA MANUAL TRAINING SCHOOL. IV. — IN THE ATELIER OF A GLASS-WORKER. THERE are few objects of manufacture which better than glass illustrate the immense preponderance in value of hu- man labor over crude material. It is a substance which might serve economists as a parallel to their favorite illustration of the comparative values of a steel watch-spring and the bit of iron- bearing earth from which it is wrought. In the case of glass, the crude materials are so plentifully dis- tributed in nature as to be almost valueless. The basis of the compound, sand, is so very abundant that it has furnished the symbol, in more than one parable, for quantity without limit. Like the unnumbered sands of the sea was a vast promise to the children of men. Somewhat less abundant than the sand are the other chemicals which it is necessary to mix with it in order to produce that double silicate which goes under the general name of glass. They are, however, far from being either scarce or ex- pensive. The alkaline ingredient, the carbonate of soda, is made from common salt, a mineral whose wide distribution in nature is at once apparent when one recalls the fact that the sea, thirty or forty times in bulk the total elevated mass of the earth, is one- vast storehouse of the substance ; that salt springs or brines abound at our very doors — in New York State, in Michigan, and in Virginia ; and that vast deposits of the solid rock-salt are to be found in Louisiana and Prussia. The third ingredient, the lime, is simply calcined limestone, a rock which forms whole ranges of hills, and is found in every corner of the globe. For the produc- tion of the fine flint glass, or crystal, which forms the special sub- ject of the glass- worker's skill, it is also necessary to add a fourth ingredient, red lead or minium.

The Rocky Mountains and the Missis- sippi Valley furnish lead ores in such abundance that the com- pounds of the metal may fairly be classed among cheap products. The total cost of the "batch" can not be more than a few cents a pound. Compare this with the value of the finished products. The finer cut glass will sell for perhaps as many dollars a pound, while the finest cameo glass may bring almost as many hundred, It must not be supposed, however, that the difference, or even the Fig. 1.— The Glass-Cctter at his Wheel. greater part of it, goes into the pocket of the manufacturer. A fair proportion reaches that destination, but by far the larger share goes for meat and bread and coal, houses and cloth, to sus- tain the life of the army of men, women, and children by whose labor these dull earths and oxides are transformed into the brill- iant carafes and bowls which adorn our dinner-table-. Much the greater part of this increased value is conferred upon the glass by the dexterous hand-work expended in the atelier, rather than by the coarser operations which attend the furnace proee— This, however, is the basis of all that follows, and the beginnings of the finest cut-glass bowl or cameo vase are to be sought in the mixing-room, where the crude materials are put together. In different establishments the proportions vary, as in the manufacture of all other forms of glass products, and even in the same establishment uniformity is far from absolute. GLASS-MAKING. 159 Although, glass is supposed to be a fairly definite chemical com- pound, each manufacturer has his own notions on the subject, and occasionally he changes his mind, or perhaps his supplies come from a different locality. The result, in either case, would be a slight change in the composition of the batch. A typical mixture would be for every hundred parts of fine white sand about forty parts of alkali (carbonate of soda), ten parts of burned lime, and forty parts of red lead. It will be noticed that the batch is essentially different from that used in the manufacture of window and Of bottle glass. It differs both in the character and the quality of the materials em- ployed. The ingredients common to the several mixtures must be much purer for use in the production of table and household glassware of the finer grades. Care is taken that the sand shall contain no iron ; and, in order to free it from any admixture of loam or other disadvantageous earthy materials, it is subjected to a washing process before it is brought to the mixing-room. By this treatment the more finely divided matter, such as clay and the like, is carried off with the water, while the coarser sand settles to the bottom of the washing-troughs. Further, in the selection of the alkali, the cheaper sulphate of soda is never substituted for the carbonate, as is frequently done in the manufacture of bottles. In the processes of the atelier the competition is a question of quality rather than of quantity. The element of human labor is so large that it would not be economical to expend it upon an in- ferior grade of glass. The workers, or rather the men who direct them, go on the principle of those wise domestic economists who reflect that the cost of labor in making up clothing is approxi- mately constant, and who therefore do not feel that they can afford to buy shoddy. The earthy materials — sand, alkali, and lime — give substance and transparency. Fused together, they form ordinary glass. The additional ingredient, the red lead, has a special function to perform It has for its immediate object an increase in the weight of the glass ; and since in general an increase in weight means an increase in refracting power, its ultimate object is an additional brilliancy in the product. Every one has noticed the heaviness of cut glass ; or, if he has not, and enters a shop to buy a piece of it, the shop-keeper is very apt to call his attention to the fact — particularly if the price be correspondingly heavy — assuming that weight is an undeniable guarantee of quality and brilliancy. If you object to the price, he puts the piece into your hands and says confidingly, " Just feel the weight of it ! * The argument is a pertinent one, but not altogether conclusive, for there are many other elements besides weight upon which the merit of the prod- uct depends. It is quite possible to have the glass too heavy for i6o THE POPULAR SCIENCE MONTHLY beauty, since the dense lead compounds have a tendency to sepa- rate from the lighter silicates, and, consequently, if present in too large amounts, they make the glass streaky and mottled. In gen- eral, lead glass for domestic uses has a specific gravity of from three to four — that is, it is from three to four times as heavy as an equal bulk of water. The brilliancy given to the glass by its increased density has attached the name crystal to this particular product. It is essential that the several ingredients should be thoroughly mixed, and to this end the operation is carried out mechanically. The materials are fed into the upper end of a slowly revolving hopper, whose axis is slightly inclined to the horizontal, and are thoroughly mixed by the time they reach the discharging end. A dainty pink pow- der falls into the re- ceiving bins. Its sub- sequent baptism by fire transforms the opaque into the trans- parent. The furnaces employed for this purpose are of the type common to other glass-melting process- es — simply a circular and intensely heated chamber, surmounted by a stack, and pro- vided with radial openings to permit the blowers to dip their blow- pipes into the molten contents of the fire-clay crucible-pots. The scene around this industrial caldron is quite as busy as that which has its center in the bottle furnace, and is even more varied. The workers are fashioning objects of the most diverse shape and for the most unlike purposes. Some are blowing lamp- chimneys, others gaslight globes, or decanters or dishes. In the center of the apartment a large press, with engraved steel dies, is squeezing the plastic " metal " — for so the glass-blower designates his still fluid glass — into decorative panels for car-windows and transoms. As one passes from one end of the large room to the other, he will see almost every conceivable shape in glass, suited Fig. 2.— The Process of Engraving on Glass. GLASS-MAKING. 161 for table or other domestic usage, taking form in the hands of the adroit workers. It is the scene of an intense and a highly ingen- ious activity. The bottles and dishes and globes intended for sub- sequent treatment in the atelier are all blown, the manipulations being varied in accordance with the special form it is desired to produce. As a rule, it may be said that it is cheaper to produce the pressed glass than the blown, since less time is required in fashioning the articles; but for the finer work the blown is always preferred, as glass worked exclusively in the air has a much more brilliant surface than that which has been formed in con- tact with the faces of the iron mold. The plain articles thus shaped are known in the trade as " blanks." The largest manufact- urers of cut and en- graved glass also make their own blanks, but there are a number of establishments which confine themselves ex- clusively to the proc- esses of ornamentation. The articles intended for such decoration go from the blower to the annealing leer, where they are permitted to pass through a cham- ber of brick- work some sixty to eighty feet long, subjected to a gradually decreasing temperature for a period of twenty-four hours or less, according to the circumstances of the work. The articles to be annealed are placed in wrought-iron cars, and are slowly moved through the leer, coming out perfectly cold. It is in this way that the blanks are prepared for the atelier proper. Here one finds a number of very interesting operations going on side by side. The untechnical visitor will perhaps be most attracted by the cutting process, since the results are so brilliant, and the articles possess so staple a value. He will get a good insight into the general principles by following the process of cutting a carafe. Fig. 3.— The Operation of making Ground Glass Globes. i6z THE POPULAR SCIENCE MONTHLY. The blank itself is perfectly plain — a simple, heavy bottle with smooth surface. Its proportions are good. The decoration is to consist of a twenty-fonr-pointed star on the bottom, a series of more or less complicated diagonal cuttings on the bulging sides, and six or eight broad facets around the neck. To these may be added a number of features of less prominence, such as a series of oval facets around the base of the carafe, and some smaller cut- tings at the top. It is the glass-worker's custom to begin with the star on the bottom. This is cut entirely by the eye, no design being traced on the glass. The first process is known technically as " roughing " it, and consists in cutting the design in the glass with coarse tools, which leave rough facets, but remove most of the glass to be cut away. The roughing- wheel is made of iron, and is about two feet in diameter. It is mounted on a horizonal axis. The face of the wheel is about seven eighths of an inch broad, and is kept supplied with a mixture of coarse sand and water allowed to constantly drip upon it from a hopper above. The wheel makes about a thousand revolutions a minute, the speed varying with the character of the work to be done. It is slower for the deeper cuttings. The workman seizes the carafe with both hands, and presses the bottom firmly against the edge' of the rotating wheel, making a cut across the center, and as far each way as it is desired to have the star extend. Then he turns the carafe around one sixth of a revolution, and makes a similar cut through the center, judging of the distance entirely by his eye. A second turn of one sixth of a revolution, and a third cut along a diameter is made. This gives a six-pointed star. The intervening spaces are then divided by similar cuts, and the spaces thus formed again divided, giving a twenty -four- pointed star. A tyro in the art would make a very poor figure of it, but the regular cutters become exceedingly expert, and are able to make comparatively perfect designs in this seemingly off-hand fashion. A trained eye will, of course, have no difficulty in detecting inac- curacies, but the designs are symmetrical enough for all purposes of decoration, The cutting does not yet possess much beauty, for its faces are as rough as ground glass. Already, however, it begins to show the promise of what it is to be. In treating the bulging sides of the carafe, greater difficulties present themselves in disposing the pattern symmetrically. It is, therefore, the custom to paint a number of guiding lines on the surface of the glass. A few cir- cular lines surrounding the carafe, and a few up-and-down lines afford a series of intersections which are sufficient to enable the cutter to develop a uniform pattern. In the same way the facets surrounding the neck are determined by a couple of limiting cir- GLASS-MAKING. 163 cles, and similarly with the secondary part of the decoration. This completes the rough work. The second process is that of " smoothing/' and is carried out by means of wheels made of a natural stone found in Scotland, known as the Craig Leigh stone. A large part of modern Edinburgh is built out of this material. It is a compact silicious stone, wearing very uniformly, and almost free from that tendency to crumble which characterizes the majority of our native sandstones. The stone wheels are about the same size as the iron wheels used in the roughing process ; but their cutting edges, instead of being smooth, are beveled, thus giving a sharp edge in the center of the face. This is occasionally sharpened by regrind- ing, or by holding pieces of flint against the beveled faces of the revolving wheel. A tiny stream of wa- ter falls constantly against the face of the stone. Each cut made on the iron wheel is gone over on the stone, and, by the finer fric- tion, the surface of the facets becomes smooth and transparent. The carafe is slowly be- coming an object of beauty. Next in the order of the processes comes the polishing, which is effected by wooden wheels mounted as be- fore and supplied with pumice or rotten-stone. Red willow is considered the best material for the polishing-wheel, though poplar is also frequently used. The hard woods are found to be less suitable for the purpose. The wooding — for so this third process is called in the atelier — gives a fine finish to the smoothed facets and adds greatly to their brilliancy. It is a process, how- ever, which is only practicable in cases where the cutting is rather deep. "Where it amounts to little more than a tracing, the wooden wheel would be of slight use. Still a fourth process is required before the carafe is ready to Fig. 4. — The Sand-Blast in Operation. 164 THE POPULAR SCIENCE MONTHLY. be washed and placed on sale. It is that of brushing. The brush is made of spun glass, and is applied in the form of a wheel as a burnisher. Those who have seen gilt used in china-painting will recall the pencils of spun glass with which the gilding is bur- nished after being fired. The rapidly revolving brush of glass cleans out the cuttings more perfectly than could be done in any other way, and adds the final luster to the facets. The carafe is now completed. Other articles are cut in much the same way, slight modifications being made to suit different shapes and pat- terns. At the present time very good copies of cut-glass articles are made in pressed goods, and at about one twentieth of the cost ; but the difference between the two products can readily be de- tected. Not only are the pressed goods less brilliant, but the edges of their facets are visibly rounded from the fusion, and fail to give the sharp, clear faces of the genuine cut glass. One can tell the fine article at once by simply rubbing his finger over the cutting. The sharp edges of the genuine article are unmistaka- ble. Another attempt to combine beauty and economy is made by cutting some prominent feature of a pressed-glass article, and letting the brilliancy thus obtained make amends for the duller facets of the less exposed portions. In this way pressed-glass de- canters are made quite presentable by being supplied with well- cut stoppers, and covered dishes pass muster through the merit of their brilliant knobs. Still another device is that of grinding off the faces of pressed-glass goods, and thus securing, as the result of a much cheaper process, the sharp edges and well -polished faces of the real cut glass. The process, however, is not a very successful one. It sounds better than it works out in practice. Wares treated in this way have the serious defect of lacking brill- iancy when compared to the air-blown glass and entire cutting. They are now made in but small quantity, for they can not com- pete in public estimation with the ordinary pressed goods, since they cost about five times as much, and are far from being five times as effective. In the most artistic circles there is at present a slight reaction against cut glass in favor of the light and graceful articles made in blown glass. But meanwhile the sale of cut glass grows larger each year, for the improvements in the method of production bring it within reach of an increasingly wide circle of buyers. It promises to remain a standard article of manufacture, for its brilliancy will always attract admirers, and any disappearance will be but temporary. The old-fashioned chandeliers and cande- labra, made with pendants of cut glass, are pushed out of the market by newer metallic goods, only to periodically reappear from their obscurity. GLASS-MAKING. 165 Alongside of the cutter's wheel one sees a corner of the atelier devoted to a species of cutting in miniature, which goes under the name of engraving. The cutting instrument is a small cop- per disk, sometimes as tiny as a dentist's tool, and sometimes sev- eral inches in diameter. It is mounted with its axis horizontal, and is made to rotate very rapidly. The cutting is lone under- pin. 5.— The Printed Designs, ready for Transference to the Glass, in the Etching Process. hand, instead of overhand, as in the former operation, which means, in the language of the outside world, that the article to he engraved is brought into contact with the rotating disk from be- neath, instead of being pressed against its upper surface. The disk is supplied with a mixture of emery and oil. This is the real cutting agent ; the disk simply applies it. In almost all cases the work is done solely by the eye, without any guiding lines what- 166 THE POPULAR SCIENCE MONTHLY. ever. Frequently the engraver originates his pattern as he goes along — a species of improvising which is quite full of interest to an on-looker. In time the men become very skillful in this sort of work, and are quite ready in thinking out new designs. It is entirely a matter of experience, the work depending largely on a nice sense of touch, since the glass is for the most part obscured by the spattered emery and oil. In this way geometric designs of considerable complication, wreaths and flowers, birds, fishes, and dragons, are traced on goblets and other table-ware, as well as on globes and similar articles. It is also the process by which initials and monograms are cut on glass, and its frequent appli- cation for this purpose is familiar to every one who is not near- sighted. The tracery is accomplished sooner than one would fancy. As a rule, it is used in connection with some other form of ornamen- tation. Frequently in the case of globes there is a light tracery around the central portion, and plain bands at the top and bot- tom. These are put on very expeditiously, and, consequently, at little cost. The process is known technically as " obscuring." The globes are mounted on a lathe over a sand-box, being fastened between plates of cork in order that they shall not be fractured by the jar. The workman presses a bundle of soft, annealed iron wire against the surface of the quickly rotating globe, and, almost in less time than it takes one to tell about it, the band is completed. The band at the other end of the globe is put on in the same way. If two parallel bands are to be put on near to- gether, the bundle of wire is in two parts, and both bands are made at the same time. The wires simply determine where the obscuring shall be. The real grinding is done by the sand and water with which the surface of the globe is kept constantly sup- plied. By using a larger bundle of wire, and passing it over the entire surface of the globe, the obscuring is made complete, and we have the so-called ground-glass globe. The obscuring process is used in connection with both cutting and engraving, a design frequently being brought out much more beautifully by reason of the obscured or translucent background. In this case, however, the cut pattern must not be subjected to the final brushing process, for the glass brush would smooth the obscured surface and give it the almost transparent character displayed by ground glass when moistened with oil or water. The effect would be to make the portion of the glass around the cutting look constantly wet — an undesirable form of decoration. Some of the most pleasing designs are thus produced by a com- bination of two or more processes. However fully and artistically a plain glass globe may be decorated, there is apt to be an un- pleasant effect of thinness of design from the unrestricted pas- GLASS-MAKING. 167 sage of the light through the transparent portions. But by ob- scuring the entire surface of * the globe, and then cutting even a very modest design upon the background so prepared, the result is much more effective. The transmitted light, from its subdued character, is also more agreeable. The cutting is done in the so- called " mud-box " — a designation which has arisen from the fact that the spent sand or mud from the cutting of heavier articles is here utilized. . Fig. 6.— Printing the Designs and Wrapping the Globes, prior to the Etching. These processes are all purely mechanical. They depend upon the direct friction between the glass and the abrading powder, or between the glass and the cutting stone, as in the case of the smoothing process. It is possible, however, to bring about this grinding action by less direct pressure. One of these indirect methods — the sand-blast — deserves particular mention, both be- cause of its commercial importance and because of its ingenuity. Some years ago there was published a book which pointed out, with more or less cunning, a prototype in nature for nearly all our mechanical devices. The author did not, I believe, mention the sand-blast, but he might well have done so, for it is a direct imitation, though perhaps an unconscious one, of a process which Nature has been using very effectively ever since the first blast of wind carried the earliest sand-grains against the Eozoic rocks. This natural sand-blast has done not a little in altering the ap- pearance of the face of the earth. In the Rocky Mountains there are many curiously sculptured rocks in the comparatively rain- less districts, which owe their carving almost entirely to this 1 68 THE POPULAR SCIENCE MONTHLY. -■ - ~~ agency. Still more striking, perhaps, has been the effect of blow- ing sand upon the monuments of antiquity. Those who have seen the Obelisk, in Central Park, New York, or have read descriptions of it, will probably recall the fact that on those sides which were originally exposed to the desert wind the hieroglyphics have been entirely worn off by the grinding action of centuries of blow- ing sand. The action is precisely the same in the atelier, except as to the matter of time. A strong blast of air, charged with par- ticles of sharp, clean sand, will obscure a plain glass surface in the course of a few seconds. It is applied very ingeniously. The design to be traced on the glass is cut out of soft rubber, and the stencil thus formed is held firmly against the surface. The blast of sand-carrying air is secured by means of an exhaust, and is so arranged that it may be made to enter a sheet-iron box placed so that its upper sur- face shall be at about the level of an ordi- nary table. There is a round opening in the top of the box, somewhat larger than the pattern to be ground, but not so large as the sheet of rubber in which it is cut. Glass and rub- ber are then pressed against the opening, and, by means of a pedal, the blast is turned on. In a very ¥§j short time, scarcely more than five or ten seconds, the blast is turned off, and the stenciled pattern is found ground on the glass. So quickly does the blast do its work that the capacity of the machine may be said to be limited only by the speed with which the operator can adjust things. The action of the blast is rather interesting. The soft-rubber stencils will endure many exposures, while the hard flint glass is perceptibly worn away in a few seconds. The reason of this is Fig. 7.— The Process of Etching. GLASS-MAKING. 169 that the little particle of moving sand can not be brought to rest immediately. However quickly its flight is arrested, there is an appreciable interval of time during which its motion must be parted with. Striking against the soft and flexible rubber, the sand is brought to rest gradually, for the rubber is sufficiently de- pressed by the Lilliputian blow to dispose of the motion stored up in the particle. When, however, the sand strikes against the hard and rigid glass, there is no giving way possible. The grains must either stop instantly or else they must penetrate between the molecules of the glass. In the latter case they would natu- rally detach little fragments in sufficient number to roughen the surface of the glass and make ■ it translucent. Experience shows that this is precisely what happens. If the naked hand be held over the blast, a pricking sensation is felt, but the skin is not broken ; it is too pliable. Thin sheet-iron stencils are sometimes substituted for those of rubber ; their elasticity makes them fairly durable. The sand-blast was invented by an American, but, as the origi- nal patent has expired, any one is at liberty to use the machine. The inventor has since made a number of modifications and im- provements, which are protected by subsequent patents. The newer form is used, I believe, more in England than in this coun- try — not so much from a failure on our part to appreciate its merits, as from a dislike of the peculiar royalty arrangements. The machines are sold, and a certain royalty charged each week, whether the works are running or not. As such an arrangement makes the expense a constant quantity, while the income is a variable, it is not acceptable to the majority of American glass- workers. Other agents besides mechanical find employment in the atelier. One of the properties of glass which makes it most highly es- teemed, in both the household and the laboratory, is its almost total indifference at ordinary temperatures to acids and other cor- rosive chemicals. It is slightly acted upon by the strongest sul- phuric acid and by steam under great pressure, but only after the lapse of considerable time. There are few substances, however, which are not, Achilles-like, vulnerable in some one particular. In the case of glass, the effective solvent is the comparatively rare compound, hydrofluoric acid. It is not strange, therefore, that in the numerous manipulations to which glass is subjected this fact should be utilized. It forms the basis of the one chemical process of the atelier, that of etching. It is a process readily and cheaply carried out, and from its effectiveness it is one of increasing im- portance. The piece of glassware to be treated is protected, in those parts which it is desired shall not be acted upon by the acid, by some substance indifferent to it, such as wax, paraffin, or a 170 THE POPULAR SCIENCE MONTHLY. specially prepared ink. The parts not coated are thus the only ones exposed when the piece is phinged into the bath of hydro- fluoric acid. They are soon bitten by the acid, and in this way the design is traced upon the glass. As globes for lamps and gas are the subjects most frequently chosen for this treatment, the process can, perhaps, best be understood by following such an article through the several stages of its decorative development. The designs are adapted from a variety of sources. The draughtsman is supplied with drawing-books containing examples of conven- tionalized flowers. From this unit he works out a design of proper size and shape — that is, something which when wrapped around the globe shall cover just one half of it, and so, by repeti- tion, the whole. He traces his designs on a panel of heavy plate Pig. 8. — Four Stages : To the right, the plain ground globe ; then the globe wrapped in printed paper; next, the printed globe, with the paper removed; and finally, to the left, the finished product. glass. The surface is coated with a special ink made of lamp- black, rosin, and wax, and the design then picked out by means of a sharp tool. The plate, thus prepared, is subjected to the action of a strongly acid bath of hydrofluoric acid for a period of from fifteen to twenty minutes. The uncovered parts of the plate are deeply eaten away. The ink is then washed off, and the plate is ready to print from. Frequently designs are etched on both sides of the panel, both for economy of material and of storage. The printing is done on a simple engraver's press, the im- pressions being taken upon smooth, white paper, somewhat heavier than tissue. As the ink used for the purpose has a decided tend- GLASS-MAKING. 1 7 1 ency to become stiff and unmanageable in the cold, a gas-flame is kept constantly burning under the engraving plate. The sheets of paper as they come from the press are covered with a thick layer of ink in those portions which correspond to the parts of the globe not to be etched. While still fresh, the printed sheets are passed to a girl sitting at a neighboring table. She cuts off the superfluous paper surrounding the design, and wraps the print around the globe to be treated. A second print serves to cover the globe completely. The paper is pressed tightly against the glass, and the wrapped-up globe then warmed over a gas-stove for a few moments. The paper is left on for a day or so, and when it is finally removed the design is found transferred to the glass. It will be seen that the process is not unlike that by which in former years decalcomania were attached to china and marble, to their supposed ornamentation. The globe is now a study in black and white, and is ready for the etching proper. The acid-room — for such is the name applied to the apartment where the etching process is carried out — is a truly villainous place. The atmosphere is so charged with hydrofluoric acid that* it has a sharp smell and a most irritating effect upon the bodily economy generally. The instantaneous photograph of the bath had to be taken with more than customary expedition, lest the ninety-dollar lens in use should be fouled by the fumes. The man in charge of the process wears rubber gloves, and has his face partially pro- tected from the fumes by a thick, bluish- white ointment. His ap- pearance, in consequence, is far from prepossessing. The protec- tion, however, is of a very superficial character. It leaves the eyes and the breathing apparatus entirely exposed. The operators soon show the ravages of the unwholesome atmosphere. Poor, pale ghosts of men, with red and blinking eyes, one wonders that, in a world so full of wholesome activities, they should be willing to sacrifice the best part of themselves in such an unnecessary cause. It is one of the saddest features of modern industrial life that things become so vastly more important than men, that both employers and employed — the responsibility is a joint one — come to look upon the ledger account as the first consideration and man- hood the second. Dainty as are the products of this industrial- ism, I find myself taking less pleasure in them as I go more among the workers, and see what a price of dull routine and unwhole- some labor is paid for the wares. If beautiful things are neces- sarily the product of unbeautiful lives, I am quite willing to forego the things. Under the present industrial regime, one feels almost an accessory to the degradation of human life if he purchase arti- cles made on a large scale under the factory system. Morally, there is complicity, however unwilling we may be to admit it. It 172 THE POPULAR SCIENCE MONTHLY. is a question worth considering whether political freedom and industrial slavery represent an ideal with which any people may worthily remain content. An industrialism is conceivable, with hours so reasonable and conditions so wholesome that the lives of the workers shall be as beautiful as the wares they produce. Whether this will result from the present competitive system car- ried to its extreme, or from a substituted co-operative system, re- mains to be seen. In the atelier, the main process in operation is the transformation of moving, human energy into the stored-up Fig. 9.— The Portland Vase. energy represented by a highly wrought product. One may be pardoned, then, if his thought turns occasionally upon the source of the energy, the man. It is not an agreeable reflection to pre- sent to the reader that the majority of our brothers in large cities are living bitter, hateful lives, but I believe that it is a true one. It is perhaps well to entertain the thought for a moment, since our people, presumably sympathetic and compassionate, not only GLASS-MAKING. 173 do not deplore this sacrifice of the best elements in human life, but on the contrary hold up as an ideal for whose protection and extension the national policy should chiefly exert itself, that very industrialism under which this sacrifice takes place. Food, cloth- ing, shelter, and the household goods and gods have value only as they minister to human life. But, by a curious inversion, these things are now held to be of greater importance than the life which they were originally intended to conserve. The savagery of modern times wears a different garb from that of the past, but it is none the less of the essence. But to return to the acid- worker, for his besmeared face and irritated eyes are still before us. The three windows of the little room in which he works are kept open winter and summer, in the hope of diluting the poisonous fumes — a clumsy arrangement at the best. It would be quite possible to have the atmosphere, if not entirely wholesome, at least comparatively so, by placing the acid bath directly under a good flue or exhaust, so that the escap- ing fumes should be drawn off artificially. Every chemist's labo- ratory contains such an evaporating closet. The hydrofluoric acid employed for etching is a chemical un- familiar to the majority of people. Its corrosive character, and the fact that it has few common uses, preclude such an acquaint- ance. The source of the acid, however, the mineral fluor-spar, is quite abundant in nature. It is so beautiful a mineral, occurring in nearly all the colors of the rainbow and in well-defined cubes and octahedra, that it is given a prominent place in all mineral- ogical cabinets. It is, therefore, probably better known than the acid derived from it. The mineral itself is a fluoride of lime, and, when treated with oil of vitriol, gives off fumes of hydrofluoric acid. These are exceedingly soluble in water, forming the ordi- nary hydrofluoric acid of commerce. The bath used in etching the globes contains in addition a certain amount of oil of vitriol. Glass plunged into such a bath will have its surface eaten away, but will remain transparent. The wooden trough containing the bath is from three to four feet long, and less than a square foot in cross-section. Half a dozen globes are treated at a time. They are mounted on a steel axle, separated from each other by washers cut out of thick rubber. These serve the double purpose of pro- tecting the glass from injury and of keeping the liquid out of the interior. When the axle is put in place in the trough, the globes are about half submerged in the bath. The axle is given a slow rotary motion, and, at the end of about fifteen minutes, the etch- ing is completed. The globes are removed from the bath, and an- other axle carrying six fresh globes put in its place. The chemi- cal action consists in the formation of gaseous fluoride of silicon, the bath affording the fluorine and the glass the silicon. It is VOL. XXXVII. — 13 i 7 4 THE POPULAR SCIENCE MONTHLY, rendered more complete and more uniform by the rotary move- ment of the axle. The globes have now only to be washed, and nothing further remains but to sell them. The etching process is completed. The solution of hydrofluoric acid leaves the etched portions of the glass transparent ; but if some alkaline salt, such as ammonium or potassium sulphate, be present in the bath, the etched portions are rendered opaque. This reaction is utilized to obscure globes, in place of the grinding process already described. The globes have only to be dipped into such a bath for a moment or so, to be thoroughly obscured. As both sides of the glass are acted upon, the process of chemical obscuring is only used where the globe is not to be further decorated. In this same department the opera- tion of "bisquing" is being carried on. If opalescent glass or colored translucent glass be dipped into such an alkaline bath for a brief, time, it will take the dull finish characteristic of bisque. Thousands of the so-called fairy lamps, in red and pink and blue opalescent glass, are treated in this manner. Glass surfaces which are subsequently to be painted on are also bisqued in order to facilitate the process. A very brief immersion makes the sur- face sufficiently rough to write on with an ordinary lead-pencil without the least difficulty. The large white plaques exposed for sale in the art-stores are prepared in this manner. The bath is contained in large wooden tanks, and the articles are simply dipped in by hand. The products of all these processes — of cutting, engraving, grinding, and etching — are all more or less beautiful. The highest excellence is attained, however, when the several processes are combined in the production of the once greatly admired cameo glass. The best of this is now manufactured in England, but it has also been made, though with less success, in America. The prototype of this variety of glass is the celebrated Port- land vase, with whose history and mishaps most people are famil- iar. It was found about the sixteenth century in a sarcophagus in the neighborhood of Rome, and for more than two centuries adorned the salon of the Barberini family. When their collection was sold, the vase was purchased by the Duchess of Portland, for eighteen hundred and seventy-two pounds, and was loaned to the British Museum. Even in such safe keeping it came very near complete destruction at the hands of a madman named Lloyd, who gave it a heavy blow with a stick. It has since been repaired with such ingenuity that one can scarcely distinguish the numer- ous fractures. The vase is supposed to date from the time of the Antonines, and is one of the finest examples of ancient glass-mak- ing extant. The body is of a deep-blue color and the raised figures are of opaque white. For many years archaeologists be- GLASS-MAKING, i 75 lieved that the vase was made of onyx, and described it as a most interesting cameo. It is now known to be made of glass composed of two layers. The Portland vase was a hint to the glass-makers, and one that they made good use of. In the most elaborate examples of the modern product three colors are employed, and the effect, if the material has been judiciously managed, is exceedingly beau- tiful. A vase is the best type of the cameo glass, since the function of the ware is almost wholly decorative. From beginning to end the process is one of great ingenuity. The basis of the vase is commonly of opalescent glass — that is, glass made opaque by the presence of some finely ground but insoluble oxide, or some such mineral as cryolite or fluor-spar. A lump of this glass is gathered on the end of the blowpipe and formed into a symmetrical shape by rolling on the marvering-table. It is then dipped at short in- tervals into two baths of molten glass of the colors desired. The composite lump is fashioned into shape by means of those various manipulations which the glass-blowers perform so adroitly. This gives a vase made up of three distinct layers of different colors. Its subsequent treatment is both chemical and mechanical. The design is painted on the glass by hand, or else transferred with special care from freshly printed paper, as in the case of the etched globes. The vase is then dipped into the bath of hydro- fluoric acid and allowed to remain until both of the outer colors on the exposed portions are eaten off. It is now taken out, the ink washed off, and its subsequent treatment intrusted to the en- graver. At this stage of the process only two out of the three colors are plainly visible, the intermediate one being seen simply as a colored line between the other two surfaces. By means of the engraving-wheel the outline of the design is made more clear cut, and enough of the outer layer removed to show the interme- diate color as a delicate shading. An immense amount of work can thus be put upon a comparatively small article, and the cost meanwhile grows in proportion. Single pieces have been manu- factured in England valued as high as two thousand dollars. In spite of its great beauty and ingenuity, however, it is an undeniable fact that the cameo glass is losing rather than gain- ing in favor with the buying public. Some of the establishments which formerly produced it have ceased to do so. Several causes have been assigned for this lessened appreciation. Manufactur- ers say that the cost has been so far reduced that the rich will not buy it, and, in consequence, the middle classes no longer care for it. But such is not the general course of events in industrial matters, and the statement is to be taken with a grain of salt. The probable trouble is, that some of the cameo-ware has been i 7 6 THE POPULAR SCIENCE MONTHLY. produced in distressing colors and in unfortunate combinations. Injudiciously managed, it is easily possible to produce meager and inartistic effects. The average buyer has, therefore, been dis- posed to reckon with himself that, dollar for dollar, he could get more beauty elsewhere, and has accordingly gone there. The intrinsic merit of the ware is such, however, that an early revival of interest in it may be expected. The processes of the atelier are much more varied than those described. These special ones have been selected as being among the most characteristic, particularly of American establishments. Moreover, they are types, and have an independent interest as ingenious adaptations of means to ends. Before closing the door upon the atelier, the factor of its per- sonnel deserves a moment's attention. I refer now to the work- ers — not in their social or human capacity, but merely as mer- chandise-producers. Their labor is expended almost exclusively in the creation of supposed beauty. It is true that the work is lavished for the most part upon objects of utility ; but still it would all fall under the head of ornamentation, since the utili- tarian quality in the products has been conferred elsewhere than in the atelier. It is curious, then, in view of this end, to find the workers of the most inartistic cult. In other departments of glass-making, and notably in the production of picture-windows, the possibilities of the material have attracted artists of the high- est rank, and the results have been quite worthy of their effort. No such artistic invasion has taken place in this department. Considering the lives and training of the workers, the surprise is that they have realized as much beauty as they have. There is nothing in the atmosphere they breathe to cultivate such a senti- ment. It is related of a celebrated Japanese cloissonne-msiker that, having acquired a considerable sum of money from the sale of some of his choice wares at one of the Paris expositions, he expended the entire amount in the creation of a beautiful garden around his work-rooms, believing that such an environment would inspire his people to produce even more beautiful wares. I presume that a spirit such as this is possible only where one works for excellence rather than for money. Accoeding to Dr. S. T. Hickson, a naturalist-traveler, the people of the island of Sangir, near Celebes, suppose that, when a man is sick, his proper soul is driven out of him and replaced by a saMt, or soul of sickness ; and they employ, to eject the evil spirit, a means of mild persuasion. God-cages or god-canoes, made of wood and ornamented with twigs and leaves, are hung up in the patient's dwell- ing, in which the sakit, if pleased with the substance and design of the structure, will take up its abode ; after which, it is supposed, the sick man will imme- diately recover. ATMOSPHERIC DUST. 177 ATMOSPHERIC DUST.* By Db. WILLIAM MARCET, F. R. S. THE infinitely small particles of matter we call dust, though possessed of a form and structure which escape the naked eye, play important parts in the phenomena of nature. A certain kind of dust has the power of decomposing organic bodies and bringing about in them definite changes known as putrefaction, while other kinds exert a baneful influence on health, and act as a source of infectious diseases. Again, from its lightness and extreme mobility, dust is a means of scattering solid matter over the earth. It may float in the atmosphere as mud does in water, and, blown by the wind, will perhaps travel thousands of miles before again alighting on the earth. Thus Ehrenberg, in 1828, detected in the air of Berlin the presence of organisms be- longing to African regions ; and he found in the air of Portugal fragments of infusoria from the prairies of America. The smoke of the burning of Chicago was, according to Mr. Clarence King, seen on the Pacific coast. Dust is concerned in many interesting meteorological phenom- ena, such as fogs, as it is generally admitted that fogs are due to the deposit of moisture on atmospheric motes. Again, the scat- tering of light depends on the presence of dust, as is shown in one of Tyndall's interesting experiments. There is no atmosphere without dust, although it varies much in quantity, from the summit of the highest mountain, where the least is found, to the low plains, at the sea-side level, where it occurs most abun- dantly. The origin of dust may be looked upon, without exaggeration, as universal. Trees shed their bark and leaves, which are pow- dered in dry weather and carried about by ever-varying currents of air ; plants dry up and crumble into dust ; the skin of man and animal is constantly shedding a fine material of a scaly form. The ground in dry weather, high roads under a midsummer's sun, emit clouds of dust consisting of very fine particles of earth. The fine river and desert sand, a species of dust, is silica ground down into a fine powder under the action of water. If the vege- table and mineral world crumbles into dust, on the other hand it is highly probable that dust was the original state of matter before the earth and heavenly bodies were formed ; and here we enter the region of theory and probabilities. While it is best to avoid as much as possible stepping out of the track of known * Abstract of an address delivered before the Royal Meteorological Society, January 15, 1890. VOL. XXXVII. — 14 i 7 8 THE POPULAR SCIENCE MONTHLY, facts, there is a limit to physical observation, and in some cases we can do no more than glance into the possible or probable source of natural phenomena. This has been done, as to the origin of the universe, by Prof. Norman Lockyer, in his article on the History of a Star. The author proposes there to clear in our imagination a limited part of space, and then set possible causes to work : that dark void will sooner or later be filled with some form of matter so fine that it is impossible to give it a chemical name ; but the matter will eventually condense into a kind of dust mixed with hydrogen gas, and constitute what are called nebulae. These nebulae are found by spectrum analysis to be made up of known substances, which are magnesium, carbon, oxygen, iron, silicon, and sulphur. This dust comes down to us in a tangible form — dust shed from the sky on the earth, and large masses, magnificent specimens of meteorites, which have fallen from the heavens at different times, some of them weighing tons. There are swarms of dust traveling through space, and their motion may be gigantic. From photo- graphs taken of the stars and nebulae, we are entitled to conclude that the swarms of dust meet and interlace each other, becoming raised by friction and collision to a very high temperature, and giving rise to what looks like a star. The light would last so long as the swarms collide, but would go out should the collision fail ; or, again, such a source of supply of heat may be withdrawn by the complete passage of one stream of dust-swarms through an- other. We shall, therefore, have various bodies in the heavens, suddenly or gradually increasing or decreasing in brightness, quite irregularly, unlike those other bodies where we get a pe- riodical variation in consequence of the revolution of one of them round the other. Hence, as Mr. Lockyer expresses it, " it can not be too strongly insisted upon that the chief among the new ideas introduced by the recent work is that a great many stars are not stars like the sun, but simply collections of meteorites, the par- ticles of which may be probably thirty, forty, or fifty miles apart." These swarms of dust undergo condensation by attraction or gravi- tation ; they will become hotter and brighter as their volume de- creases, and we shall pass from the nebulae to what we call true stars. Mr. Lockyer imagines such condensed masses of meteoric dust being pelted or bombarded by meteoric material, producing heat and light, the effect continuing as long as the pelting is kept up. To this circumstance is due the formation of stars like suns. Our earth originally belonged to that class of heavenly bodies, but from a subsequent process of cooling assumed its present character. The dust scattered everywhere in the atmosphere, which is lighted up in a sunbeam or a ray from the electric lamp, is of ATMOSPHERIC DUST. 179 an organic nature. It is seen to consist of countless motes, rising, falling, or gyrating, although it is impossible to follow any of them with the eye for longer than a fraction of a second. We conclude that their weight exceeds but very slightly that of the air ; and, moreover, that the atmosphere is the seat of multitudes of minute currents, assuming all kinds of directions. One day last June, from the top of Eiffel's Tower in Paris, I amused my- self by throwing an unfolded newspaper over the railing round the summit of the tower. At first it fell slowly, carried away by a light breeze ; but presently it rose, and, describing a curve, began again to fall. As it was vanishing from sight, the paper seemed to me as if arrested now and then in its descent, perhaps under- going again a slight upheaval. Here was, indeed, a gigantic mote floating in the atmosphere, and subject to the same physical laws, though on a larger scale, as those delicate filaments of dust we see dancing merrily in a sunbeam. It is difficult to say how much of the dust present in the air may become a source of disease, and how much is innocuous. Many of the motes belong to the class of micro-organisms ; and experiments show how easily these micro-organisms or sources of infectious diseases can reach the lungs, and do mischief if they should find a condition of the body on which they are able to thrive and be reproduced. Atmospheric motes, although it has been shown that they are really deposited in the respiratory organs, do not accumulate in the lungs and air-passages, but un- dergo decomposition and disappear in the circulation. Smoke, which is finely divided coal-dust, is clearly subjected to such a destructive process ; otherwise the smoky atmosphere of many of our towns would soon prove fatal, and tobacco-smoke would leave a deposit interfering seriously after a very short time with the process of respiration. Dust, however in its physical aspect is very far from being always innocuous, and many trades are liable to suffer from it. The cutting of chaff, for horses' food, is one of the most pernicious occupations, as it generates clouds of dust of an essentially penetrating character. Persons engaged in needle manufacturing and steel - grinders suffer much from the dust of metallic particles. Stone-cutters, and workmen in plaster of Paris, coal-heavers, men engaged in the manufacture of cigars and rope, those employed in flour-mills and hat and carpet mak- ing, are liable to suffer from dust. A number of methods have been adopted, more or less successfully, to rid these trades of the danger due to this source. I observed many years ago that char- coal has the power of retaining dust in a remarkable degree, and having had respirators made of it, found them very effective in preventing dust reaching the lungs. Micro-organisms — dust-like particles capable of cultivation or 180 THE POPULAR SCIENCE MONTHLY. reproduction in certain media and at certain temperatures — are scattered everywhere in the atmosphere. Interesting inquiries into their distribution in air and water have been made by Dr. Miquel at the Montsouris Observatory, Paris, and by Dr. Percy Frankland in England. Dr. Frankland has found that the num- ber present is much reduced in winter. Experiments made in in- closed places, where there is little or no aerial motion, show the number of suspended organisms to be very moderate ; but as soon as any disturbance in the air occurs, from draughts or people moving about, the number rapidly increases and may become very great. Being slightly heavier than air, they have an invari- able tendency to fall, and on that account collect on the surface of water. Hence rivers, lakes, and ponds are constantly being thus contaminated. Important points connected with dust of organic origin are its inflammability and its liability to explode when mixed with air. The property of explosiveness was forcibly illustrated in the de- struction of six flour-mills by this cause in Minneapolis, Minn., in May, 1878. Coal-dust in coal-mines is a cause of accident from explosions which has been closely investigated in England, Ger- many, and other mining countries. The subject was thoroughly treated by Sir Frederick Abeel, in a paper on Accidents in Mines, read before the Institution of Civil Engineers in 1888. Extremely fine particles of mineral dust may exist in the at- mosphere, and do exist there more frequently than is generally thought, while they escape detection by our senses. The author, while making experiments on the Peak of Teneriffe, in 1878, found the knife-edges of his balance so clogged with this invisible dust that the balance refused to act. When wiped off, the dust col- lected again in a few minutes, and it was only by continually wiping it away that he was able to go on with his investiga- tion. Prof. Piazzi Smyth, while on the Peak of Teneriffe, wit- nessed strata of dust rising to a height of nearly a mile, reaching out to the horizon in every direction, and so dense as to hide fre- quently the neighboring hills. Prof. S. P. Langley, looking down from the height of fifteen thousand feet on Mount Whitney, Cali- fornia, into a region that had appeared clear from the valley below, saw " a kind of level dust ocean, invisible from below, but whose depth was six or seven thousand feet, as the upper portion only of the opposite mountain-range rose clearly out of it." Dust storms are classified by Dr. Henry Cook, according to their intensity, as atmospheric dust, dust columns, and dust storms. Dr. Cook has observed in India that there are some days on which, however hard and violently the wind may blow, no dust accom- panies it, while on others every little puff of air or current of wind forms or carries with it clouds of dust. If the wind which ATMOSPHERIC BUST. 181 raises the dust is strong, nothing will be visible at the distance of a few yards, and the snn will be obscured. The dnst penetrates everywhere, and can not be excluded from honses, boxes, and even watches, however carefully guarded. The individual particles of sand appear to be in such an electrical condition that they are ever ready to repel each other, and are consequently disturbed and carried up into the air. Dust columns are regarded by Dr. Cook as due to electrical causes. On calm, quiet days, when hardly a breath of air is stirring, and the sun pours down its heated rays with full force, little eddies arise in the atmosphere near the surface of the ground. These increase in force and diam- eter, catching up and whirling round bits of sticks, grass, dust, and lastly sand, until a column is formed of great height and con- siderable diameter, which usually, after remaining stationary for some time, sweeps away across country at great speed. Ultimately it loses gradually the velocity of its circular movement and dis- appears. In the valley of Mingochar, which is only a few miles in width, and surrounded by high hills, Dr. Cook, on a day when not a breath of air was stirring, counted upward of twenty of these columns. They seldom changed their places, and, when they did so, moved but slowly across the level tract. They never inter- fered with one another, and appeared to have independent exist- ences. Mr. P. L. H. Baddeley, in his book on Whirlwinds and Dust Storms of India, tells of a gentleman at Lahore who fixed an electrometer apparatus, so adjusted as to report atmospheric elec- trical movements, and observed that it was strongly affected dur- ing dust storms. Volcanic dust consists mainly of powdered vitrified substances reduced by the action of intense heat. It is interesting in many respects. The ashes or scoria shot out in volcanic eruptions are mostly pounded pumice, but they also originate from stones and fragments which are pulverized by striking against each other. Volcanic dust has a whitish-gray color, and is sometimes nearly white. Thus it is that, in summer, the terminal cone of the Peak of Teneriff e appears from a distance as if covered with snow ; but there is no snow on the mountain at that season of the year, and the white cap of the peak is due to pumice ejected centuries ago. The friction caused by volcanic stones and rocks as they are crushed in their collision develops a mass of electricity which shows itself in brilliant displays of branch lightning darting from the edges of the dense ascending column. During the great erup- tion of Vesuvius in 1822 they were constantly visible, and added much to the grandeur of the spectacle. It not unfrequently hap- pens that the dust emitted from Vesuvius falls into the streets of Naples ; but this is nothing in comparison with the mass of finely powdered material which covered and buried the towns of Pompeii, i8z THE POPULAR SCIENCE MONTHLY, Herculaneum, and Stabise, in the year 79. The eruption of Kra- katoa, in 1883, exceeded, in all probability, in its deadly effects, and as a wonderful phenomenon of nature, the outburst of Vesu- vius in the year 79. It is shown, in the report of the Krakatoa Committee of the Royal Society, that the detonations caused by the explosive action were heard a hundred and fifty miles away. Captain Thompson, of the ship Medea, sailing at a point seventy- six miles northeast of Krakatoa, saw a black mass like smoke rising into the clouds to an altitude which was estimated as not less than seventeen miles. All the eye-witnesses agree as to the splendor of the electrical phenomena. The old crater of Krakatoa was eviscerated, and a cavity was formed more than a thousand feet deep. On the morning of the 27th of August three vessels at the eastern entrance of the Strait of Sunda encountered the fall of mingled dust and water, which soon darkened the air, and cov- ered their decks and sails with a thick coating of mud. Some of the pieces of pumice falling on the Sir R. Sale were said to have been of the size of a pumpkin. All that day the three vessels were beating about in darkness, pumice-dust falling upon them in such quantities as to employ the crews for hours in shoveling it from the decks and in beating it from the sails and rigging. The speed and distance attained by the pumice ejected from the volcano may be conceived from the fact stated in Mr. Douglas Archibald's con- tribution to the report, that dust fell on September 8th more than thirty-seven hundred English miles from the seat of the eruption. The great mass of the pumice was of a dirty, grayish-white tint, and was very irregular in size. The dust ejected from Krakatoa did not all fall back at the same time upon the sea and the earth. The lightest portion formed into a haze, which was as a rule propagated westward. Most ob- servers agree in regarding this haze as the proximate cause of the twilight glows, colored suns, and large corona which were seen for a long time (more than two years) after the eruption. The haze was densest in the Indian Ocean and along the equatorial belt, and was often thick enough to hide the sun when within a few degrees of the horizon. I hope I have succeeded in showing that infinitely small ob- jects, no larger than particles of dust, act important parts in the physical phenomena of nature. Mr. H. "W. Seton-Karr tells, in one of his books of travels, of his ascent of one of the spurs of Mount St. Elias, following the track of a brown bear with always an uneasy expectation of meeting the animal itself, to the height of seven thousand two hundred feet. Here the wonderful spectacle was presented of no less than seventeen thousand square miles of glaciers stretching over the face of the country. Excepting Greenland, according to this traveler, these glaciers are the most extensive in the world outside of the arctic and antarctic regions. ON JUSTICE. 183 ON JUSTICE. By HERBERT SPENCER. [Conclu de d. ] IV. The Sentiment of Justice. — Acceptance of the doctrine of organic evolution determines certain ethical conceptions. The doctrine implies that the numerous organs in each of the innu- merable species of animals, have been either directly or indirectly molded into fitness for the requirements of life by constant con- verse with those requirements. Simultaneously, through nervous modifications, there have been developments of the sensations, instincts, emotions, and intellectual aptitudes, needed for the ap- propriate uses of these organs ; as we see in caged rodents that exercise their incisors by purposeless gnawing, in gregarious creat- ures which are miserable if they can not join their fellows, in beavers which, kept in confinement, show their passion for dam- building by heaping up whatever sticks and stones they can find. Has this process of mental adaptation ended with primitive man ? Are human beings incapable of having their feelings and ideas progressively adjusted to the modes of life imposed on them by the social state into which they have grown ? Shall we sup- pose that the nature which fitted them to the exigencies of sav- age life has remained unchanged, and will remain unchanged, by the exigencies of civilized life ? Or shall we suppose that this aboriginal nature, by repression of some traits and fostering of others, is made to approach more and more to a nature which finds developed society its appropriate environment, and the required activities its normal ones ? There are many believers in the doctrine of evolution who seem to have no faith in the con- tinued adaptability of mankind. While glancing but carelessly at the evidence furnished by comparisons of different human races with one another, and of the same races in different ages, they ignore entirely the induction from the phenomena of life at large. But if there is an abuse of the deductive method of reasoning there is also an abuse of the inductive method. One who refused to believe that a new moon would in a fortnight become full, and, disregarding observations accumulated throughout the past, in- sisted on watching the successive phases for three weeks before he was convinced, would be considered inductive in an irrational degree. But there might not unfairly be classed with him those who. slighting the inductive proof of unlimited adjustability, bod- ily and mental, which the animal kingdom at large presents, will not admit the adjustability of human nature to social life until the adjustment has taken place : nay, even ignore the evidence that it is taking place. i8 4 THE POPULAR SCIENCE MONTHLY. Here we shall assume it to be an inevitable inference from the doctrine of organic evolution, that the highest type of living being, no less than all lower types, must go on molding itself to those requirements which circumstances impose. And we shall, by implication, assume that moral changes are among the changes thus wrought out. The fact that when surfeit of a favorite food has caused sick- ness, there is apt to follow an aversion to that food, shows how, in the region of the sensations, experiences establish associations which influence conduct. And the fact that the house in which a wife or child died, or in which a long illness was suffered, be- comes so associated with painful states of mind as to be shunned, sufficiently illustrates, in the emotional region, the mode in which actions may be determined by mental connections formed in the course of life. When the circumstances of a species make certain relations between conduct and consequence habitual, the appro- priately-linked feelings may come to characterize the species. Either inheritances of modifications produced by habit, or more numerous survivals of individuals having nervous structures which have varied in fit ways, gradually form guiding tenden- cies, prompting appropriate behavior and deterring from inap- propriate. The contrast between fearless birds found on islands never before visited by man, and the birds around us, which show fear of man immediately they are out of the nest, exemplifies such adaptations. By virtue of this process there have been produced to some ex- tent among lower creatures, and there are being further produced in man, the sentiments appropriate to social life. Aggressive ac- tions, while they are habitually injurious to the group in which they occur, are not unfrequently injurious to the individuals committing them ; since, though certain pleasures may be gained by them, they often entail pains greater than the pleasures. Con- versely, conduct restrained within the required limits, calling out no antagonistic passions, favors harmonious co-operation, profits the group, and, by implication, profits the average of its indi- viduals. Consequently, there results, other things equal, a tend- ency for groups formed of members having this adaptation of nature, to survive and spread. Among the social sentiments thus evolved, one of chief impor- tance is the sentiment of justice. Let us now consider more closely its nature. Stop an animal's nostrils, and it makes frantic efforts to free its head. Tie its limbs together, and its struggles to get them at liberty are violent. Chain it by the neck or leg, and it is some time before it ceases its attempts to escape. Put it in a cage, and ON JUSTICE. 185 it long continues restless. Generalizing these instances we see that in proportion as the restraints on actions by which life is maintained are extreme, the resistances to them are great. Con- versely, the eagerness with which a bird seizes the opportunity for taking flight, and the joy of a dog when liberated, show how strong is the love of unfettered movement. Displaying like feelings in like ways, man displays them in other and wider ways. He is irritated by invisible restraints as well as by visible ones ; and as his evolution becomes higher, he is affected by circumstances and actions which in more remote ways aid or hinder the pursuit of ends. A parallel will elucidate this truth. Primitively the sentiment of property is gratified only by possession of food and shelter, and, presently, of cloth- ing ; but afterward it is gratified by possession of the weapons and tools which aid in obtaining these, then by possession of the raw materials serving for making weapons and tools and for other purposes, then by possession of the coin which purchases them as well as things at large, then by possession of promises to pay exchangeable for the coin, then by a lien on a banker, regis- tered in a pass-book. That is, there comes to be pleasure in an ownership more and more abstract and remote from material sat- isfactions. Similarly with the sentiment of justice. Beginning with the joy felt in ability to use the bodily powers and gain the resulting benefits, accompanied by irritation at direct interfer- ences, this gradually responds to wider relations: being excited now by the incidents of personal bondage, now by those of politi- cal bondage, now by those of class privilege, and now by small political changes. Eventually, this sentiment, sometimes so little developed in the negro that he jeers at a liberated companion because he has no master to take care of him, becomes so much developed in the Englishman that the slightest infraction of some mode of formal procedure at a public meeting or in Parliament which can not intrinsically concern him, is vehemently opposed because in some distant and indirect way it may help to give possible powers to unnamed authorities who may perhaps impose unforeseen burdens or restrictions. Clearly, then, the egoistic sentiment of justice is a subjective attribute which answers to that objective requirement consti- tuting justice — the requirement that each adult shall receive the good and evil effects of his own nature. For unless the faculties of all kinds have free play, these results can not be gained or suf- fered, and unless there exists a sentiment which prompts mainte- nance of the sphere for this free play, it will be trenched upon and the free play impeded. While we may thus understand how the egoistic sentiment of justice is developed, it is much less easy to understand how there 186 THE POPULAR SCIENCE MONTHLY. is developed the altruistic sentiment of justice. On the one hand, the implication is that the altruistic sentiment of justice can come into existence only in the course of adaptation to social life. On the other hand the implication is that social life is made possible only by maintenance of those equitable relations which imply the altruistic sentiment of justice. How can these reciprocal require- ments be fulfilled ? The answer is that the altruistic sentiment of justice can come into existence only by the aid of a sentiment which temporarily supplies its place and restrains the actions prompted by pure ego- ism — a pro-altruistic sentiment of justice as we may call it. This has several components which we must successively glance at. The first deterrent from aggression is one which we see among animals at large — the fear of retaliation. Among creatures of the same species the food obtained by one or place of vantage taken possession of by it, is in some measure insured to it by the dread which most others feel of the vengeance which may follow any attempt to take it away ; and among men, especially during primi- tive stages of social life, it is chiefly such dread which secures for each man free scope for his activities, and exclusive use of what- ever they bring him. A further restraint is the fear of reprobation shown by uncon- cerned members of the group. Though in the expulsion of a " rogue " elephant from the herd, or the slaying of a sinning mem- ber of the flock by rooks or storks, we see that even among ani- mals individuals suffer from an adverse public opinion ; yet it is scarcely probable that among animals expectation of general dislike prevents encroachment. But among mankind, " looking before and after " to a greater extent, the thought of social dis- grace is usually an additional check on ill-behavior of man to man. To these feelings, which come into play before there is any social organization, have to be added those which arise after political authority establishes itself. When a successful leader in war acquires permanent headship, and comes to have at heart the maintenance of his power, there arises in him a desire to prevent the trespasses of his people one against another ; since the result- ing dissensions weaken his tribe. The rights of personal venge- ance and, as in feudal times, of private war, are restricted ; and, simultaneously, there grow up interdicts on the acts which cause them. Dread of the penalties which follow breaches of these, is an added restraint. Ancestor-worship in general, developing as the society devel- ops into special propitiation of the dead chiefs ghost, and pres- ently the dead king's ghost, gives to the injunctions he uttered during life increased sanctity ; and when, with establishment of ON JUSTICE. 187 the cult, he becomes a god, his injunctions become divine com- mands with dreaded punishments for breaches of them. These four kinds of fear co-operate. The dread of retaliation, the dread of social dislike, the dread of legal punishment, and the dread of divine vengeance, united in various proportions, form a body of feeling which checks the primitive tendency to pursue the objects of desire without regard to the interests of fellow-men. Containing none of the altruistic sentiment of justice, properly so called, this pro-altruistic sentiment of justice serves temporarily to cause respect for one another's claims, and so to make social co-operation possible. Creatures which become gregarious tend to become sympa- thetic in degrees proportionate to their intelligences. Not, in- deed, that the resulting sympathetic tendency is exclusively, or even mainly, of that kind which the words ordinarily imply ; for in some there is little beyond sympathy in fear, and in others little beyond sympathy in ferocity. All that is meant is that in gregarious creatures a feeling displayed by one is apt to arouse kindred feelings in others, and is apt to do this in proportion as others are intelligent enough to appreciate the signs of the feel- ing. In two chapters of the Principles of Psychology — Sociality and Sympathy and Altruistic Sentiments — I have endeavored to show how sympathy in general arises, and how there is eventually produced altruistic sympathy. The implication is, then, that the associated state having been maintained among men by the aid of the pro-altruistic sentiment of justice, there have been maintained the conditions under which the altruistic sentiment of justice itself can develop. In a per- manent group there occur, generation after generation, incidents simultaneously drawing from its members manifestations of like emotions — rejoicings over victories and escapes, over prey jointly captured, over supplies of wild food discovered ; as well as la- ments over defeats, scarcities, inclemencies, etc. And to these greater pleasures and pains felt in common by all, and so express- ing themselves that each sees in others the signs of feelings like those which he has and is displaying, must be added the smaller pleasures and pains daily resulting from meals taken together, amusements, games, and from the not infrequent adverse occur- rences which affect several persons at once. Thus there is fos- tered that sympathy which makes the altruistic sentiment of justice possible. But the altruistic sentiment of justice is slow in assuming a high form, partly because its primary component does not become highly developed until a late phase of progress, partly because it is relatively complex, and partly because it implies a stretch of 188 THE POPULAR SCIENCE MONTHLY. imagination not possible for low intelligences. Let us glance at each of these reasons. Every altruistic feeling presupposes experience of the cor- responding egoistic feeling. As, until pain has been felt there can not be sympathy with pain, and as one who has no ear for music can not enter into the pleasure which music gives to oth- ers ; so, the altruistic sentiment of justice can arise only after the egoistic sentiment of justice has arisen. Hence where this has not been developed in any considerable degree, or has been re- pressed by a social life of an adverse kind, the altruistic senti- ment of justice remains rudimentary. The complexity of the sentiment becomes manifest on observ- ing that it is not concerned only with concrete pleasures and pains, but is concerned mainly with certain of the circumstances under which these are obtainable or preventable. As the egoistic senti- ment of justice is gratified by maintenance of those conditions which render achievement of satisfactions unimpeded, and irri- tated by the breaking of those conditions, it results that the altru- istic sentiment of justice requires for its excitement not only the ideas of such satisfactions, but also the ideas of those condi- tions which are in the one case maintained and in the other case broken. Evidently, therefore, to be capable of this sentiment in a devel- oped form, the faculty of mental representation must be relatively great. Where the feelings with which there is to be sympathy are simple pleasures and pains, the higher gregarious animals occasionally display it : pity and generosity are from time to time felt by them as well as by human beings. But to conceive simul- taneously not only the feelings produced in another, but the plexus of acts and relations involved in the production of such feelings, presupposes the putting together in thought of more elements than an inferior creature can grasp at the same time. And when we come to those most abstract forms of the sentiment of justice which are concerned with public arrangements, we see that only the higher varieties of men are capable of so conceiving the ways in which good or bad institutions and laws will eventually affect their spheres of action, as to be prompted to support or oppose them ; and that only among these, therefore, is there excited un- der such conditions that sympathetic sentiment of justice which makes them defend the political interests of fellow-citizens. There is, of course, a close connection between the sentiment of justice and the social type. Predominant militancy, by the coercive form of organization it implies, alike in the fighting body and in the society which supports it, affords no scope for the egoistic sentiment of justice ; but, contrariwise, perpetually tramples on it, and at the same time the sympathies which origi- ON JUSTICE. 189 nate the altruistic sentiment, of justice are perpetually seared by- militant activities. Contrariwise, in proportion as the regime of status is replaced by the regime of contract, or, in other words, as fast as voluntary co-operation, which characterizes the industrial type of society, becomes more general than involuntary co-opera- tion, which characterizes the militant type of society, individual activities become less restrained, and the sentiment which rejoices in the scope for them is encouraged ; while, simultaneously, the occasions for repressing the sympathies become less frequent. Hence during warlike phases of social life the sentiment of jus- tice retrogrades, while it advances during peaceful phases, and can reach its full development only in a permanently peaceful state.* V. The Idea of Justice. — While describing the sentiment of justice, the way has been prepared for describing the idea of justice. Though the two are intimately connected they may be clearly distinguished. One who had dropped his pocket-book, and, turning round, finds that another who has picked it up will not surrender it, is indignant. If the goods sent home by a shopkeeper are not those he purchased, he protests against the fraud. Should his seat at a theatre be usurped during a momentary absence he feels himself ill-used. Morning noises from a neighbor's poultry he complains of as grievances. And meanwhile he sympathizes with the anger of a friend who has been led by false statements to join a disas- trous enterprise, or whose action at law has been rendered futile by a flaw in the procedure. But though in these cases his sense of justice is offended, he may fail to distinguish the essential trait which in each case causes the offense. He may have the senti- ment of justice in full measure while his idea of justice remains vague. This relation between sentiment and idea is a matter of course. The ways in which men trespass on one another become more nu- merous in their kinds, and more involved, as society grows more complex ; and they must be experienced in their many forms, gen- eration after generation, before analysis can make clear the essen- tial distinction between legitimate acts and illegitimate acts. A special reason for this should be recognized. Ideas as well as sentiments must on the average be adjusted to the social state. Hence, as war has been frequent or habitual in nearly all societies, such ideas of justice as have existed have been perpetually con- * Permanent peace does in a few places exist, and where it exists the sentiment of jus- tice is exceptionally strong and sensitive. I am glad to have again the occasion for point- ing out that among tribes called uncivilized, there are some, distinguished by the entire absence of warlike activities, who in their characters put to shame the peoples called civilized. In Political Institutions, §§ 437 and 574, I have given eight examples of this connection of facts taken from races of different types. i 9 o THE POPULAR SCIENCE MONTHLY. fused by the conflicting requirements of internal amity and exter- nal enmity. Already it has been made clear that the idea of justice, or at least the idea of human justice, contains two elements. On the one hand there is that positive element implied by recognition of each man's claims to unimpeded activities and the benefits they bring. On the other hand there is that negative element implied by the consciousness of limits which the presence of other men having like claims necessitates. Two opposite traits in these two components especially arrest the attention. Inequality is the primordial idea suggested. For if the prin- ciple is that each shall receive the benefits and evils due to his own nature and consequent conduct, then since men differ in their powers there must be differences in the results of their actions. Unequal amounts of benefit are implied. Mutual limitations to men's actions suggest a contrary idea. When it is seen that if each pursues his ends regardless of his neighbor's claims, quarrels must be caused and social co-opera- tion hindered, there arises the consciousness that bounds must be set to the doings of each ; and the thought of spheres of action bounded by one another, involves the conception of equality. Unbalanced appreciations of these two factors in human justice lead to divergent moral and social theories, which we must now glance at. In some of the rudest groups of men the appreciations are no higher than those which we see among inferior gregarious ani- mals. Here the stronger takes what he pleases from the weaker without exciting general reprobation ; while, elsewhere, there is practiced and tacitly approved something like communism. But where habitual war has developed political organization, the idea of inequality becomes predominant. If not among the conquered, who are made slaves, yet among the conquerors, who naturally think of that which conduces to their interest as that which ought to be, there is fostered this element in the conception of justice which asserts that superiority shall have the benefits of superiority. Though the Platonic dialogues may not be taken as measures of Greek belief, yet we may reasonably assume that the things they take for granted were currently accepted. Socrates inquires — " Do you admit that it is just for subjects to obey their rulers ? " ' I do," replies Thrasymachus.* Though otherwise in antagonism, * The Republic, Book I, translated by Jowett, p. 159 (edit, of 1871). Instead of " Do you admit," the rendering given by Messrs. Llewelyn Davies and Yaughan is " You doubt- less also maintain." ON JUSTICE. 191 the two agree in this conception of what is just. At a later stage of the inquiry, Glaucon, describing a current opinion, says : " This, as they affirm, is the origin and nature of justice: — there is a mean or compromise between the best of all, which is to do and not to suffer injustice, and the worst of all,, which is to suffer without the power of retaliation ; and justice being the mean between the two, is tolerated not as good, but as the lesser evil." And immediately afterward it is said that men " are only diverted into the path of justice by the force of law." * In this significant passage several things are to be noted. There is first a recognition of the fact, above indicated, that at an early stage the practice of justice is initiated by the dread of retaliation, and the conviction, suggested by experience, that it is on the whole the best to avoid aggression and to respect the limit which compromise implies ; there is no recognition of intrinsic flagitiousness in aggression, but only of its impolicy. Further, the limit to each man's actions, described as " a mean of compro- mise," and respect for which is called " the path of justice," is said to be established only " by the force of law." Law is not considered as an expression of justice otherwise cognizable, but as itself the source of justice ; and hence results the meaning of the preceding proposition, that it is just to obey the law. Thirdly, there is an implication that were it not for retaliation and legal penalties, the stronger might with propriety take ad- vantage of the weaker. There is a half -expressed belief that su- periority ought to have the advantages of superiority ; inequality occupies a prominent place, while equality makes no definite appearance. The conception here indicated that justice consists in legality, is, toward the close of Book IV, developed into the conception that justice consists " in each of the three classes doing the work of its own class " : carpenter, shoemaker, or what not, " doing each his own business, and not another's " ; and all obeying the class whose business it is to rule.f Thus the idea of justice is made to include the idea of inequality. Though there is some recog- * Book II, p. 229. f On another page there is furnished a typical example of Socratic reasoning. It is held to be a just " principle that individuals are neither to take what is another's, nor to be deprived of what is their own." From this it is inferred that justice consists in " hav- ing and doing what is a man's own " ; and then comes the further inference that it is unjust for one man to assume another's occupation, and " force his way " out of one class into another. Here, then, because a man's own property and his own occupation are both called his own, the same conclusion is drawn concerning both. Two fallacies are in- volved — the one that a man can " own " a trade in the same way that he owns a coat, and the other that because he may not be deprived of the coat he must be restricted to the trade. The Platonic dialogues are everywhere vitiated by fallacies of this kind, caused by confounding words with things — unity of name with unity of nature. i 9 2 THE POPULAR SCIENCE MONTHLY. nition of equality of positions and claims among members of the same class, yet the regulations respecting community of wives, etc., in the guardian-class, have for their avowed purpose to establish, even within that class, unequal privileges for the benefit of the superior. But now observe that while in the Greek conception of justice there predominates the idea of inequality, while the idea of equal- ity is inconspicous, the inequality refers, not to the natural achievement of greater rewards by greater merits, but to the artificial apportionment of greater rewards to greater merits. It is an inequality mainly established by authority. The gradations in the civil organization are of the same nature as those in the military organization. Regimentation pervades both, and the idea of justice is everywhere conformed to the traits of the social structure. And this is the idea of justice proper to the militant type at large, as we are again shown throughout Europe in subsequent ages. It will suffice to point out that along with the different law-established positions and privileges of different ranks, there went gradations in the amounts paid in composition for crimes according to the rank of the injured. And how completely the idea of justice was determined by the idea of rightly-existing in- equality, is shown by the condemnation of serfs who escaped into the towns and were said to have " unjustly " withdrawn them- selves from the control of their lords. Thus, as might be expected, we find that while the struggle for existence between societies is going on actively, recognition of the primary factor in justice which is common to life at large, human and sub-human, is very imperfectly qualified by recogni- tion of the secondary factor. That which we may distinguish as the brute element in the conception is but little mitigated by the human element. All movements are rhythmical, and among others social move- ments, with their accompanying doctrines. After that concep- tion of justice in which the idea of inequality unduly predomi- nates, comes a conception in which the idea of equality unduly predominates. A recent example of such reactions is furnished by the ethical theory of Bentham. As is shown by the following extract from Mr. Mill's Utilitarianism (p. 91), the idea of inequality here en- tirely disappears : The Greatest-Happiness Principle is a mere form of words without rational signification, UDless one person's happiness, supposed equal in degree (with the proper allowance made for kind), is counted for exactly as much as another's. Those conditions being supplied, Bentham's dictum, " everybody to count for one, ON JUSTICE. 193 nobody for more than one, 11 might be written under the principle of utility as an explanatory commentary. Now though Bentham ridicules the taking of justice as our guide, saying that while happiness is an end intelligible to all, justice is a relatively unintelligible end, yet he tacitly asserts that his principle — " everybody to count for one, nobody for more than one/' is just ; since, otherwise, he would be obliged to admit that it is unjust, and we may not suppose he would do so. Hence the implication of his doctrine is that justice means an equal appor- tionment of the benefits, material and immaterial, which men's activities bring. There is no recognition of inequalities in men's shares of happiness, consequent on inequalities of their faculties or characters. This is the theory which Communism would reduce to prac- tice. From one who knows him, I learn that Prince Krapotkin blames the English socialists because they do -not propose to act out the rule popularly worded as " share and share alike." In a recent periodical, M. de Laveleye summed up the communistic principle as being " that the individual works for the profit of the State, to which he hands over the produce of his labor for equal division among all." In the communistic Utopia described in Mr. Bellamy's Looking Backward, it is held that each " shall make the same effort," and that if by the same efforts, bodily or mental, one produces twice as much as another, he is not to be advantaged by the difference. At the same time the intellectually or physic- ally feeble are to be quite as well off as others : the assertion being that the existing regime is one of " robbing the incapable class of their plain right in leaving them unprovided for." The principle of inequality is thus denied absolutely. It is assumed to be unjust that superiority of nature shall bring supe- riority of results, or, at any rate, superiority of material results ; and as no distinction appears to be made in respect either of phys- ical qualities or intellectual qualities or moral qualities, the im- plication is not only that strong and weak shall fare alike, but that foolish and wise, worthy and unworthy, mean and noble, shall do the same. For if, according to this conception of justice, defects of nature, physical or intellectual, ought not to count, neither ought moral defects, since they are one and all primarily inherited. And here, too, we have a deliberate abolition of that cardinal distinction between the ethics of the family and the ethics of the State emphasized at the outset : an abolition which must eventu- ate in decay and disappearance of the species or variety in which it takes place. After contemplation of these divergent conceptions of justice, in which the ideas of inequality and equality almost or quite ex- VOL. XXXVII. — 15 i 9 4 THE POPULAR SCIENCE MONTHLY. elude one another, we are prepared for framing a true conception of justice. In other fields of thought it has fallen to niy lot to show that the right view is obtained by co-ordinating the antagonist wrong views. Thus, the association-theory of intellect is harmonized with the transcendental theory on perceiving that when, to the effects of individual experiences are added the inherited effects of experiences received by all ancestors, the two views become one. So, too, when the molding of feelings into harmony with require- ments, generation after generation, is recognized as causing an adapted moral nature, there results a reconciliation of the ex- pediency-theory of morals with the intuitional theory. And here we see that the like occurs with this more special component of ethics now before us. For if each of these opposite conceptions of justice is accepted as true in part, and then supplemented by the other, there results that conception of justice which arises on contemplating the laws of life as carried on in the social state. The equality concerns the mutually-limited spheres of action which must be maintained if associated men are to co-operate harmoniously. The inequality concerns the results which each may achieve by carrying on his actions within the implied limits. No incongruity exists when the ideas of equality and inequality are applied the one to the bounds and the other to the benefits. Contrariwise, the two may be, and must be, simultaneously asserted. Other injunctions which ethics has to utter do not here concern us. There are the self-imposed requirements and limitations of private conduct, forming that large division of ethics treated of in Part III ; and there are the demands and restraints included under Negative and Positive Beneficence, to be hereafter treated of, which are at once self-imposed and in a measure imposed by public opinion. But here we have to do only with those claims and those limits which have to be maintained as conditions to harmonious co-operation, and which alone are to be enforced by the society in its corporate capacity. Any considerable acceptance of so definite an idea of justice is not to be expected. It is an idea appropriate to an ultimate state, and can be but partially recognized during transitional states ; for the prevailing ideas must, on the average, be congruous with ex- isting institutions and activities. The two essentially-different types of social organization, mili- tant and industrial, based respectively on status and on contract, have, as we have above seen, feelings and beliefs severally ad- justed to them ; and the mixed feelings and beliefs appropriate to intermediate types, have continually to change according to the • ON JUSTICE. i 95 ratio between the one and the other. As I have elsewhere shown,* during the thirty — or rather forty — years' peace, and consequent weakening of the militant organization, the idea of justice became clearer : coercive regulations were relaxed and each man left more free to make the best of himself. But, since then, the redevelop- ment of militancy has caused reversal of these changes ; and, along with nominal increases of freedom, actual diminutions of freedom have resulted from multiplied regulations and exactions. The spirit of regimentation proper to the militant type has been spreading throughout the administration of civil life. An army of workers with appointed tasks and apportioned • shares of prod- ucts, which socialism, knowingly or unknowingly, aims at, shows in civil life the same characters as an army of soldiers with pre- scribed duties and fixed rations shows in military life ; and every further act of Parliament which takes from the individual money for public purposes and gives him public benefits, tends more and more to assimilate the two. Germany best shows this kinship. There, where militancy is most pronounced, and where the regu- lation of citizens is most elaborate, socialism is most highly devel- oped ; and from the head of the German military system has now come the proposal of regimental regulations for the working classes throughout Europe*. Sympathy which, a generation ago, was taking the shape of justice, is relapsing into the shape of generosity ; and the gener- osity is exercised by inflicting injustice. Daily legislation betrays little anxiety that each shall have that which belongs to him, but great anxiety that he shall have that which belongs to somebody else For Wliile no energy is expended in so reforming our judi- cial administration that every one may obtain and enjoy all he has earned, great energy is shown in providing for him and others benefits which they have not earned. Along with that miserable laissez-faire which calmly looks on while men ruin themselves in trying to enforce by law their equitable claims, there goes activity in supplying them, at other men's cost, with gratis novel- reading !

EVIDENCES OF GLACIAL ACTION IN SOUTH- EASTERN CONNECTICUT. By Hon. DAVID A. WELLS. EEMARKABLE evidences of glacial action in southeastern Connecticut seem thus far to have almost entirely escaped the attention of geologists. In fact, the most superficial survey of the section of country bordering on Long Island and Fisher's Island Sounds, and extending from Connecticut River on the west to Watch Hill, and perhaps to a point farther east, in Rhode Island, can hardly fail to produce a conviction that it was in this region that one, at least, of the great New England glaciers debouched into the waters of the Atlantic ; unloading or drop- FlG. 1. ping, as its progress was arrested by the ocean, or as it subse- quently gradually wasted and receded by change of climate, a vast multitude of bowlders, of which a very large proportion are of uncommon magnitude. There would also seem some reasons for believing that the central or medium line of this glacier is now indicated by the course of the so-called Thames River — which is more properly an arm of the sea rather than a river — EVIDENCES OF GLACIAL ACTION IN CONNECTICUT. 197 and represents a deep but comparatively narrow cut in the under- lying hard granitic rocks ; and which, certainly near its mouth, to a depth of fifty feet or more beneath. the present river-bottom, as was shown by the recent borings in connection with the con- struction of the Shore Line Railroad Bridge at New London, is now filled up with mud or coarser detritus. East of the mouth of the Thames River the shores of the mainland, and the surface of the numerous little adjoining islands, are strewed with bowl- ders — many of large size, and often resting on a highly smoothed basis of bed-rock without the intervention of any surface soil whatever; as is illustrated by Fig. 1, which represents (from a photograph) a bowlder (and the changes in the way of destruc- tion which such masses of rock are undergoing), between Groton and Noank, on the line of the New London and Providence Rail- road, and which is a very conspicuous object as seen from the cars, on the left hand side of the track going east.* The number and size of the bowlders that are strewed over the bottom of Fisher's Island Sound are also a matter of interest and Vza. 2. wonderment to even those least acquainted with the subject, who sail over and fish in its shallow waters ; while Fisher's Island itself is little other than a mass of bowlders covered in great part by sand, and probably marks the terminal line where a heavy ocean surf arrested the further progress of the glacier by * All the illustrations accompanying this paper are reproduced from photographic pictures. 198 THE POPULAR SCIENCE MONTHLY. breaking in upon its structure, floating off its ice-fragments in the form of bergs or floes, and, by releasing at the same time its heavier rock and gravel . constituents, built up a breakwater which, as an island, now forms what is known as " Fisher's Island Sound." Fig. 2 represents a not unfrequent example of the char- acter of the materials which enter into the construction of this natural breakwater, as seen from the western side of this island. But it is in the region to the east and west of the line of the Thames River, and which it has been suggested may have been the axis of the ancient glacier, and not very far removed from this line, that bowlders of extraordinary size occur most numer- ously ; and among them is a rock which until very recently has been regarded as one of the largest, if not the very largest, bowl- der that has thus far been recognized in this or any other coun- try. This rock — of coarse crystalline granite — is situated in the town of Montville, New London County, about six miles south of Norwich, and about a mile west of the Montville Station on the New London and Northern Railroad ; and, under the Indian name of ' Sheegan," has almost from the first settlement of the country been recognized as a great natural curiosity. Its posi- tion is on the edge of a gentle mound or knoll, on the northeast slope of a little valley ; and its dimensions, according to recent EVIDENCES OF GLACIAL ACTION IN CONNECTICUT. 199 measurements by Prof. Crosby, of the Boston Society of Natural History, are as follows : northwest side, forty-six feet ; northeast, fifty-eight ; southeast, forty-five ; southwest, seventy. Maximum height, reckoning from the lower or down-hill side, to the highest point on the upper side, approximately, sixty feet ; approximate cubic contents, seventy thousand cubic feet ; approximate weight, about six thousand tons. Other and former reported measure- ments of this rock indicate much larger dimensions than those reported by Prof. Crosby ; and, although the determinations of an expert observer like the latter are entitled to the greatest confidence, it is nevertheless true that the form of the rock is so irregular as to render an exact estimate of its size, cubical con- tents, and weight a matter of no little difficulty. Figs. 3 and 4 give an idea of the position, size, and appearance of the " Sheegan " Eock, as seen from the valley beneath it, looking west. The intro- duction into the picture of the horse and wagon beneath the rock affords in some degree a standard for estimating its height. The cavity or recess beneath the rock, which is said to have been occupied, at the time of the first settlement of the country, by a Fig. 4. Mohegan Indian (from whom the rock undoubtedly derived its name) as a dwelling-place, is sufficiently capacious to admit of being used as a place of shelter for the sleds and other farm implements of the farmer proprietor. A rude ladder on the southern side of the rock affords facilities for reaching its top and obtaining a somewhat extensive view of the surrounding country. It will probably have been noticed in the above description 200 THE POPULAR SCIENCE MONTHLY. that the expression, " has been regarded " as a bowlder, has been employed. The reason of this is, that a recent examination of this rock (in March, 1890) has led Prof. Crosby to the somewhat start- ling conclusion that it is not a bowlder, but " simply an angular and prominent remnant of a large granite vein, still undisturbed in its original position upon beds of gneiss ; and that its chief geological interest is found in the fact that, notwithstanding its Fig. 5. exposed position, it has survived the disintegrating influence of the elements and successfully resisted the pressure of the great ice-sheet." Prof. Crosby also states that, " through the undercut- ting action of the frost, forming quite an extensive rock-shelter " (i. e., the cavity or recess on the lower or valley side), " is afforded an opportunity to observe the actual contact of the massive gran- ite and the finely laminated micaceous gneiss " upon which the granite rests. For one of very limited experience to dispute the conclusions of such a trained observer as Prof. Crosby would be presumpt- uous ; and yet it would not seem unreasonable to ask that they should not be considered as entirely determinative without a further careful examination of the problem on the part of ex- perts. The question as to whether the contact of the granite of the assumed bowlder and the underlying gneiss is one of situ- ation or of composition is not an easy one for decision, without a very clear opportunity for examination. The fact that such a EVIDENCES OF GLACIAL ACTION IN CONNECTICUT. 201 huge mass of granite should have resisted the pressure of a great ice-sheet, and remained so prominently in place as part of a vein, when such pressure and an accompanying movement and grind- ing were sufficient to not only round off and obliterate everything like angularity from the granite surface, but also remove or re- duce down to a much lower level and over a large proximate area the whole vast mass of rock on which the granite protuberance, if it be a portion of a vein, must have been as it were originally imbedded, is, as Prof. Crosby admits, a result not a little singular. There is certainly nothing analogous to such a phenomenon in the vicinity, and it may well be questioned whether there is any- thing similar anywhere. Furthermore, as throwing some light on this subject, there are, as before stated, in comparative proximity to the " Sheegan " Rock, a large number of undoubted bowlders of .the same granite, which, though not comparable as regards size, may yet be regarded as extraordinary, and as clearly involving the exercise of an enor- mous disrupting and transporting power within a rather limited area. One of these bowlders in the same township of Montville, which is also an object of public curiosity, and known as the " Goal " Rock, is, according to measurements made for the writer, twenty-one feet high, twenty-five long, and twenty-five thick. Another, in the vicinity of Gardner's Lake, from which nearly one fourth of the original mass has been detached in fragments, is reported as eighteen feet six inches high, thirty-five feet long, and twenty feet thick. A third, on the east side of the Thames River, in the town of Preston, is fourteen feet high, twenty feet long, and seventeen feet thick ; and at least three or four others in the same region, of similar dimensions, might be enumerated. Above a mile east of " Allen's Point," and on one of the highest of the elevations bordering the river, an area of several acres is so covered with huge bowlders that in places it is difficult to find a path through them ; while the -southern slope of the same ele- vation, not far removed, is so strewed with such a multitude of rounded, small bowlders that they have the appearance of having been planted artificially. Fig. 5 represents an extremely picturesque though not a very large bowlder, on the road between Norwich and Taftville, on the lands of the Ponemah Manufacturing Company, and almost in the center of the village that has within a comparatively few years grown up about it ; and which, most fortunately, has thus far been carefully protected by the company against the Vandalic spirit which is so often prompted to mutilate or destroy everything in the nature of a public curiosity. VOL. XXXVII. — 16 202 THE POPULAR SCIENCE MONTHLY, UTILITY IN ARCHITECTURE. By BARK FEEEEE. IT is a significant commentary on the actual state of our culture that architecture, the most ancient and grandest of the arts, is to-day the least understood, the least satisfactory, the least appreciated of all the achievements of our civilization. This is the more remarkable because there are few periods so prolific of building as our own. There have been times when great and splendid works have been raised by some ambitious ruler who has produced monuments quite unlike anything that is under- taken at the present ; but, while we erect no costly palaces or mag- nificent temples, we build thousands of smaller structures whose combined cost in any one year or term of years greatly exceeds the sums expended on the most elaborate edifices of antiquity in the same time. This is especially the case in our own country, where there is a constant and active demand for buildings of all kinds, for the most expensive as well as the cheapest, for state use and for the individual citizen. And yet, in spite of this undi- minished call, which in any department of trade or of manufact- ures would at once produce the very best results and the most satisfactory methods, the architecture of our time is so thoroughly bad, so wanting in the first principles of common sense, so de- based, that this noblest of all the arts is scarcely included in the term, and our critics speak patronizingly of it as just being " gradually recognized " as such. Architecture has an historical chronology of at least four thou- sand years during which we can trace its growth, and in which it expressed in a very thorough manner the conditions under which it was developed. It has been reserved for the superior knowledge of modern times to cast it aside as one of the peculiar products of a less intelligent age, as something to admire for its past monu- ments, but as being quite out of our modern ideas of progress. Because in the last few years a partial revival has taken place ; because it has been discovered that it offers a convenient and expensive way of impressing the beholder with the importance of the builder ; because our rich men and large corporations want to give some visual evidence of their resources — it has been taken up as something that may be approved of as a means of testifying to the wealth of our cities and adding to their general good looks. The very art element of architecture has been the cause of its degradation. From the most useful of arts, it has become mostly ornamental. From meaning and expressing the utility of an edi- fice, it has come to refer to its appearance only. People have for- UTILITY IN ARCHITECTURE. 203 gotten that it arose from the necessity of man for shelter, and view it as a product of the study or of "the studio in which beauty and sesthetic effects are the only ends sought, while utility, con- venience, expression of intention, have all become secondary con- siderations. Nothing could "be more erroneous, nothing more fatal to the production of sound architecture. Architecture is not the product of the imagination, but the result of experience and foresight. The painter in his studio, or the sculptor in his, has nothing to dictate to his thoughts or force them into certain channels. His fancy is free, and he allows it to carry him where it will. The architect, on the other hand, is limited by innumerable requirements and difficulties, all of which are real and physical, and all of which must be overcome before his work can be a success. His creations are not intended for the decoration of a gallery or to be preserved under glass, but they must stand the test of time and of climate, must bear a relation to the manners and customs of the day. He must exer- cise care and discrimination in the selection of his materials. He must count their cost and be fully acquainted with their phys- ical properties. There is, in fact, no end to the details he must consider, in all of which there is no place or opportunity for the exercise of the imagination. His art is the product of natural conditions, and may be not inappropriately compared to a plant which, through the action of certain external elements or forces, finally assumes a character that can be directly traced to the en- vironment, and which is, in fact, directly dependent on it. These views are not those popularly held on the subject, but it is impossible to make an intelligent study of the history of the art without reaching them, if, indeed, they had not been already indicated by common sense. Of all the arts, architecture calls, for the greatest exercise of thought ; yet, strangely enough, this is the very element that is most wanting in it at the present day. All successful buildings must express an idea ; they must mean something. The architecture of previous times rests on this basis, and those structures which give the most evidence of the fact are the most successful. Even in the distorted view of our day those buildings which depart from this position are the most condemned. Yet the very people who censure such lack of judgment by their ancestors do not hesitate to follow in their footsteps and produce architectural monstrosities that should never have been conceived in an intelligent age. The very rudest of African savages is fully aware of this important fact, and keeps it well in mind in building such structures as the simple needs of his life and his primitive ideas require. Thus, for example, he will build a very different edifice for a granary than he will to live in. It has been reserved for the 204 THE POPULAR SCIENCE MONTHLY. nineteenth, century, with its great wealth, its boundless resources, and its extensive and diversified knowledge, to cast this cardinal principle to one side. Savages may, indeed, be foolish enough, to build houses which, exactly express the life of their builders and answer every requirement of their primitive form of existence, but we of this time are above such, petty expedients, and can well afford to conform our lives to our architecture. We do not need to make our architecture conform to ourselves. Judging from the monuments of our time, the view that archi- tecture is not ornamentation but construction, not for beauty but for utility, not for an elaborate exterior but for a well-devised in- terior, not for something pleasing to look at, but for something to live in or to be put to a certain well-defined purpose, is not one that has any considerable support. A glance at a few of the chief points of architectural history will show how true this is, and to what an extent it underlies all that is good in the building art. It is characteristic of the earliest stages of society, those in which architecture had its birth, that nothing is built without a reason. Then people had too few ideas, were provided with too limited means, to be able, on the one hand, to think of unnecessary erec- tions, or, on the other, to do more than was called for by abso- lute necessity. Architecture was barren of ornament, and had a crudeness that is almost repulsive to modern eyes ; but, never- theless, primitive buildings answered their purpose, as a rule, much more satisfactorily than many later ones. Illustrations of structures in which use, not beauty, is the cen- tral idea, are to be found among the masters of art in antiquity. The Egyptians, Assyrians, Greeks, Romans, all followed this leading idea. There are, indeed, instances where the folly of a wealthy tyrant has produced an overloading of ornament, an un- necessary multiplication of details, and a striving after effect has led to the employment of bad methods ; but these exceptions do not disprove the rule. On the contrary, these very structures are censured for their violation of this fundamental principle, and it is those in which it is adhered to most closely that excite our admiration and esteem. Utility, then, being the first element of successful architecture, it follows that the structure of buildings varies according to the use to which they are to be put. This proposition is self-evident, and expresses only ordinary common sense. It would scarcely call for demonstration, were it not for the fact that many modern buildings are constructed on the basis that, if they look well, whether the outward form is suitable or not for the purpose for which they are intended, or whether the exterior expresses the interior in any way, all has been done that is required. A very different state of affairs existed in the past. The ancient Egyp- UTILITY IN ARCHITECTURE. 205 tians, for example, adopted a totally different style of architect- ure for their temples or palaces than they did for their dwellings. The former were of stone, and of a massive method of building that was intended to withstand the wear and tear of ages ; the latter were of wood or brick, constructed in a light manner, and without much concern as to their durability. The Romans sup- ply another illustration of the same fact. These people were un- questionably the greatest builders the world has seen, and the methods they employed can properly serve as a guide for later usage. Much of their architecture, judged by the pure standard of the Greek, on which it largely rested, is bad from an aesthetic point of view, and not a little of their construction was devised on methods that can not always be approved of ; but, apart from this, the buildings of the Romans offer many interesting exam- ples of the application of idea to structure, and- the importance of utility over mere questions of art. It has been remarked that in ancient Rome no one ever had a doubt as to the use to which any building was put or what it was ; and, in truth, great as was the variety of Roman buildings, their forms were so many, their plans so varied and so well ex- pressed in the structure, that there never could have been room for the smallest doubt on the subject. The temple" differed from the basilica, the basilica from the amphitheatre, the amphitheatre from the palace, the palace from the baths. In a word, each class of buildings had its own form, its own plan, which was based, not on some fancy of the architect, not on some individual caprice, not on some mistaken idea of the beautiful, but on the single thought that if the building answered its purpose it was satisfac- tory and accomplished all that was to be expected of it. In the golden age of the Roman Empire enormous sums of money were spent in adorning the capital and chief cities with public works — buildings not only for the emperor himself but for public and state use as well. The display of wealth and luxury was lavish in the extreme ; ornament and decoration were to be seen in every available place in the greatest profusion ; yet in the midst of all this gorgeousness the Roman architect never forgot the destina- tion of the building. If a complicated structure, like a bath, was needed, there was no limit to the extent to which the plan was elaborated ; if a simple edifice was required, such as a basilica, there was no multiplication of parts for external effect, but simply the large hall and the necessary rooms. The ornament was fre- quently profuse and much overdone, but the architecture proper, the structure itself, the plan, the essential part, was never any- thing else than what it was intended to be. There is nothing astonishing in this method, which is only the application of common sense to art and the subordination of orna- 2 o6 THE POPULAR SCIENCE MONTHLY. ment to the requirements of the time. It would not call for com- ment were it not that modern builders so persistently refuse to recognize it as a fundamental principle in building. Nowadays, when an architect designs a building, he is satisfied he has done all he is required to do if it looks well. If the builder of a house wants a stairway or a window in a particular place because he thinks it will be more convenient, and thereby interferes with the symmetry of the drawing that is submitted for his inspection, he is argued out of it because, forsooth, it will destroy this carefully prepared symmetry or spoil some technical gimcrack that the architect regards as his chief device ; and if by chance the owner carries the day, the architect retires in chagrin, and despairs of his art ever making good progress. No greater harm is done to the true advancement of architect- ure than this insistence that exterior effect is the sole end to be de- sired. More than any other cause it has operated to depress the art, and helped to make people question the utility of intrusting their interests to the architects. It has spread abroad the impression that these gentlemen, who might be very useful, are unnecessary luxuries, and that a much more comfortable dwelling can be built by indicating one's own desires and following one's own sugges- tions and views as to convenience, than by paying large sums for "pretty" facades that very likely conceal more discomfort and dissatisfaction than the most vivid imagination can conceive of in a twelvemonth. As a natural result there is a popular skepticism as to the value of professional services that not only hinders the development of a modern architecture, but does serious injury to the profession as well. Yet architects have only themselves to thank for this condition of things, and they can never hope to win the confidence of the public until they have laid aside their so- called art, and begun to design structures with the sole end of making them answer the requirements for which they are in- tended. The most remarkable movement in modern architecture has been the Gothic revival, in the midst of which we are living. It has resulted in the wholesale approval of all that is mediaeval, and all that bears the impress of Gothic art. It is important, not only as showing an interest in the really good work of previous times, but as indicating an appreciation for an art that is based on com- mon sense and the adaptation of ends to means. Gothic architect- ure is nothing if not sensible. It originated in a time in the world's history when building was at its lowest ebb. The found- ers of Gothic art were possessed of limited means ; they were without wealth, and their general knowledge was of the scantiest. The magnificent structures to which the Romans had been accus- tomed were impossible to them. Every stone counted, every item UTILITY IN ARCHITECTURE. 207 of expenditure was rigorously scrutinized and, if not essential, cast to one side as a luxury that was unnecessary and could not be afforded. It followed, therefore, that a Gothic building had no superfluous parts, no erections intended solely for effect, noth- ing that was not absolutely essential. There was no unnecessary multiplication of detail ; there was no attempt at a refined balance of parts or at symmetry. Symmetrical building is the greatest bugbear that besets the modern architect, and has done more to throw him into disrepute than any other invention of the craft. The making of two parts of a building the same, whether their use was identical or not, is a very recent invention, and, though practiced by the Romans to a limited extent, was almost unknown prior to the fourteenth century. Every style has permitted more or less irregularity, according as the plan required it, and it was not. until the Renais- sance — a movement that is responsible for more architectural sins than is generally supposed — that the astonishing idea was pre- sented to the world that all the corresponding parts of a building must be alike. The Egyptians, Assyrians, Greeks, Romans, and the architects of mediaeval Europe, were all equally free and un- symmetrical in their designs and their methods. Even the Greeks, who produced more symmetrical buildings than any other people of antiquity, varied their designs to suit circumstances. It is needless to multiply examples, and it is sufficient to point out that this freedom from restraint, this ability to vary the design, is one of the chief glories of Gothic architecture, and helps make it applicable to the varied requirements of modern life. Yet this very freedom militates against the use of Gothic, and is one of the reasons why it is not as satisfactory for modern re- quirements as it ought to be. The capability for constant varia- tion permits the architect to compose designs of not a little beauty and almost infinite variety, which so fascinate him that in his search for a pleasing facade he forgets that the external ap- pearance of his building may not conform to the best plan or the greatest convenience. The new Law Courts in London furnish a remarkable illustration of this. These buildings were designed by one of the leaders of the Gothic movement — Sir George Gilbert Scott — a man who was thoroughly imbued with the Gothic spirit, and who devoted his life to the propagation of Gothic forms. Yet he so far overlooked the prime element of Gothic architecture — utility — that the completed structures have been found totally un- suited for the purposes for which they were intended. It can not be wondered at that, when those to whom we look for guidance fail, there should be so many smaller failures by those not so well equipped, and who can not, therefore, be expected to have the same knowledge. There can be no surprise that there has been a revul- 208 THE POPULAR SCIENCE MONTHLY. sion against Gothic art, which, bids fair to reach such proportions as to once more drive it out of- use. There is nothing more misunderstood at the present day than Gothic architecture. It is popularly supposed that if a building has a sloping roof, and is plentifully adorned with buttresses, pin- nacles, towers, arches, balconies, dormers, and similar things, it is in the correct form of that order. Gothic architecture is, indeed, characterized by all these objects in one shape or another ; but the mere placing of them in juxtaposition no more produces it than does the placing alongside of each other water, flour, and yeast make bread. It is the proper and due combination of these constituents that produces the desired result in each case. Gothic buildings have sloping roofs, because the style originated in a part of the world where the rainfall was abundant, and some de- vice was needed to throw off the water. They have arched open- ings, because practical experiments in building have demon- strated that they are the most economic and safe form to use. They have buttresses and pinnacles, because they were necessary to resist the thrust of a vaulted roof. In the best Gothic not one of these forms was used unless it was an essential part of the con- struction. The moment one is applied to a building for orna- mental purposes, or for any object other than as a necessity to its statical condition, the structure ceases to be Gothic and becomes a hybrid without a name. Gothic architecture never employed a form that was not neces- sary. In this respect it offers a striking contrast to what is now called modern Gothic, which consists in applying ornament to sur- faces and giving them forms which have no real meaning of their own, and are nothing more than ornamentation. A building does not become Gothic simply because it has a gable or a carved door- frame ; the principle, the cause which made them Gothic in the old form, is wanting, because from parts of the structure they have become mere pieces of decoration. Gothic architecture is expressed by many forms ; but its true character lies not in them, but in the application of sound constructive methods to the sci- ence of building. It is this principle that gives it a glory of its own, and it is the violation of this fundamental element which renders the Gothic architecture of the present day so unsatis- factory and so un-Gothic in spirit. But there is another element of Gothic architecture that calls for consideration, and that is, that notwithstanding it could be varied and each part made to be exactly what it was intended to be without regard to the total effect, the results are perfectly satis- factory from an aBsthetic standpoint. It shows, in a conclusive manner, that a building can be erected with the sole aim of being useful and answering exactly the requirements for which it is UTILITY IN ARCHITECTURE. 209 designed, and at the same time be of sufficient beauty to call forth, the commendation of future ages. In other words, utility in architecture is not synonymous with ugliness, nor does it follow that, because a structure is essentially useful, it is any the less beautiful. This fact is of great importance, because many modern builders have the singular idea that beauty of form and utility of structure are mutually antagonistic. The Gothic builders, for instance, employed the grandest forms and the most ambi- tious designs for their cathedrals; but, when they set about building a dwelling or a warehouse, kept their designs well within the limits for which they were intended. They used the same shapes, the same details, the same ideas, it is true ; but the applica- tion of them is different in a dwelling from that in a church. Modern architects, on the contrary, do not hesitate to apply forms and methods that are peculiarly ecclesiastical, and which have no significance in any other connection, to domestic work ; and it is no unusual thing to-day to see a castle turret decorating the cor- ner of a thoroughfare, or a church doorway leading into a financial institution. A confusion naturally ensues as to the use of the structure, and the average spectator is frequently at a loss to know for what purpose a particular building is intended. In mediaeval times such a condition would have been impossible, because then the idea that intention was the chief thing to be ex- pressed in a structure was so firmly imbedded that any other process would never have been thought of. It goes without saying that, if an adherence to this principle produced satisfactory results in past times, the same methods would bring about equally good ones at the present day. And yet the thought is so far forgotten as to be seldom practiced. Not all the architecture of the present time is bad, but so much of it is, that no opportunity should be neglected of hastening a reform. Our political thought is directed toward reform ; we have ballot reform, civil-service reform, tariff reform, and very shortly the art world must have architectural reform, or it will be impossible to live in our houses. In place of use, we are given ornament ; in place of intention, we have design. On every side buildings are criticised for their appearance, and are generally found unsatisfac- tory — a state of affairs that can be directly traced to their lack of ideas. Music is flat and insipid just so far as ideas are absent from it, and the same may be said of architecture. There are un- rivaled opportunities for good work and plenty of it in this coun- try, and yet there is a constant cry of dissatisfaction with the products of our architectural labor. Government architecture is as bad as that produced under private auspices. In ancient Rome it was the government's work that was the best done and has survived the longest. In the nineteenth century it is the private 210 THE POPULAR SCIENCE MONTHLY. work that reaches a respectable age, while that done by the gov- ernment undergoes a rapid decay. The difference between the ancient and the modern method is enormous, and it needs no guide to tell which is the better. In our time, in our country at least, government architecture is considered of more importance for its effect on the " boys " than for any direct relation to the progress of art. There is no limit to the expenditures that are made on our large public buildings, but they are no sooner com- pleted than extensive repairs are necessary that not infrequently amount to as much as the original cost. Nothing could be worse than this, yet it is happening every day. Our streets are lined with hideous structures and comfort- less dwellings. Lighting and ventilation, plumbing and heating, and all the requirements of our daily life, are sunk into subordi- nate positions beside the questions of external effect and the sup- port of a large number of political hangers-on whose interest in architecture terminates with the job. It is evident that this can not be continued indefinitely. Sooner or later there will come a revulsion in public feeling, and an insistence that our architecture shall express our civilization in its fullest development, regardless of designs or exteriors. The direction in which we are working is essentially bad ; and it is manifest that, if they did things bet- ter in past time, when utility was the prime consideration, the sooner we return to primitive methods the better it will be. It is a lasting disgrace to our culture that the Bushman and the Hot- tentot, the Indian and the Patagonian have ideas in architecture that put our own attempts to the blush and will render us a laugh- ing stock to posterity. The instincts of animals, even, teach them ways and means of construction that are far in advance of the methods of the men of the nineteenth century. Did not the wise man say go to the ant and consider her way and be wise ? The architecture of the past teaches us many facts of interest and value, but none more important than this, that a building must express an idea. It must not seem to be what it is, but be it, without any uncertainty or doubt. In the structures now going up around us, in this land as well as in other lands, this essen- tial element is apt to be found wanting. There are too many buildings that need repairs and alterations before they can be occupied. There are too many structures erected for external effect, without due regard to the planning and the use to which they are to be put. There is too much drawing of pretty plans and elevations on paper, without proper attention to structural re- quirements. There is too much haste, too much careless manage- ment, too much poor construction, too much attention to detail, too much bad taste. As a result, our buildings are bad in concep- tion and execrable in execution. "We must not condemn a build- EDUCATION AND CRIME. 211 ing f or some unpleasant detail, some crude idea. Nothing could be less proper ; no building, no matter what its form, should be condemned until we know its purpose, and whether it fills it or not. The very fact that it is necessary to speak of " knowing the purpose " of a building shows how thoroughly the art has degen- erated. ■♦•» EDUCATION AND CRIME. By Rev. A. W. GOULD. IN the January number of The Popular Science Monthly there was an article by Benjamin Reece on Public Schools as affect- ing Crime and Vice. In that article Mr. Reece mentions the fact that " in the decade ending with 1880, population having increased thirty per cent and illiteracy only ten per cent, the number of criminals present the alarming increase of eighty-two per cent." And he asks : " Can it be possible that with greater educational fa- cilities there is to be increased crime ? Perish the thought ! Yet if the instruction of our common schools subdues the tendency to crime,' why is it that the ratio of prisoners, being one in every 3,442 in 1850, rose to one in every 1,647 in 1860, one in 1,021 in 1870, and one in 837 in 1880 ? " He tells us further that " the illiterates of the United States comprise seventeen per cent of the total pop- ulation. . . . The general average of illiteracy is exceeded by ev- ery one of the original slave States with the exception of Missouri, but the average ratio of the mentally and morally unsound is only reached in the State of Maryland. South Carolina, which shows the highest percentage of illiterates, presents the lowest average of any State in the Union as regards insanity and crime " ; and his conclusion is that " our condition of decreasing illiteracy and increasing crime" means that "in the adjustment of our schools we have gone too far in our aim for material advance- ment and development of wealth, and that we are correspond- ingly losing in the direction of moral growth and culture." In other words, he thinks that the United States census proves that the increase of prisoners in our prisons is the result of the increase of pupils in our schools. And as I find that these " novel and threatening facts" have aroused some apprehension among those interested in our public-school system, it seems to me desira- ble that some one should point out the figures in our census which seriously modify, if not wholly destroy, Mr. Reece's alarming in- ference that our public schools are nurseries of crime. Figures, like Bible-texts, may not lie, but they can be made to prove almost anything ; and it would not be difficult to establish, by our census figures, the exact opposite of Mr. Reece's conclu- 212 THE POPULAR SCIENCE MONTHLY. sion, if we may be allowed to use the same reasoning that he does. For his statistics only show that crime and edncation are both increasing. But that does not prove that the increase in educa- tion is the cause of the increase in crime. Diseases have increased during the past half-century, and so has medical skill ; but that does not prove that the one increase was caused by the other. Perhaps the increase of diseases would have been far greater had it not been for the increase in the power to cope with them. So education may, for aught Mr. Reece's statistics prove, be the only thing that prevents a still more rapid growth in crime. The statistics of our last report show that the most enormous strides in developing a criminal class have been taken in those States where ignorance, and not education, most aboimds. If we take the ten States that have the largest number of citizens un- able to write, we shall find that from 1850 to 1880 the ratio of their prisoners has increased over fivefold, from one in 5,400 to one in 970 ; from 1860 to 1880 it has grown threefold, or from one in 3,600 to one in 970 ; while the ten States that have the fewest citizens unable to write have swelled the proportion of their criminals only threefold for the longer period and only fifty per cent for the shorter — the figures being, for 1850 one in 3,100, for 1860 one in 1,500, and for 1880 one in 1,050. So that in the States of greatest illiteracy the relative increase of criminals during the last twenty years has been six times as rapid as in the States of least illiteracy. And if we ask in what classes the most ignorance is to be found, our census tells us that the foreign-born are fifty per cent more illiterate than the natives, and the blacks seven times as illiterate as the whites ; and our census tells us. further that the foreign- born furnish one hundred per cent more than their share of crimi- nals, and the blacks one hundred and fifty per cent more than their share. Do not these facts prove that the advance in crime is the result not of education but of the absence of education ? We might think so, if figures had not that reprehensible habit of being all things to all men. Therefore, we may find, upon a more careful examination, that there is some other cause than ignorance for this rapid growth of our prison population in certain parts of our country. If I am not mistaken, there are several such causes, some of them entirely independent of the change in the illiteracy of the nation. One of them lies in the transition from an unsettled con- dition to a settled condition on our constantly advancing frontier : another is in the change from slavery in the South ; and, a third is in the gradual elevation of the standard of human conduct, mak- ing crimes of actions that had been only lawful escapades in ear- lier times. The first cause comes out clearly if we compare the ten States EDUCATION AND CRIME. 213 that were on the frontier in 1850 with ten older States— the New England and Middle States, for instance. In the former the ratio of criminals has been multiplied four or five times during the past thirty years, while in the latter it has only doubled, rising from 244 to 1,148 prisoners in a million inhabitants on the frontier, and from 450 to 1,074 on the seaboard. Of course, it is obvious that in a new country there will be a certain amount of lawless conduct unpunished at first, before sheriffs, courts, and jails are in running order. But the rapid increase in the proportion of criminals, as the State grows older, does not mean more crime ; it often means less. The evil-doers are arrested and sentenced, and so get into our prisons and our census ; and then we are told that crime is increasing. Kansas had only 289 prisoners to each million of inhabitants in the decade before the rebellion, while it had 1,300 to the same number in the last report ; yet every one knows that this State was a far more dangerous place at the ear- lier time than now. Colorado had only 477 offenders per mill- ion at its first census, in 1870, but in 1880 it reported 1,950, a gain of nearly fivefold in a single decade ; while on the other hand the older States, like New Hampshire and Connecticut, showed an actual decrease in percentage during these periods. But the transition from slavery to freedom was a far more efficient cause in swelling the ratio of this class. If we compare ten of the original slave States with our ten New England and Middle States, we shall find that the increase in crime in the slave States has been three or four times as great as in the free States. The former had, for each million of population, only 161 criminals in 1850, and 240 the next decade. But in 1870 they had 829, and in 1880 1,166. This was an increase of sevenfold, while the free States only a little more than doubled their criminal element. That this was the result of the emancipation is seen in many ways. The sudden leap shows it between the decade before and after the war, or between 1860 and 1880, if 1870 be thought too near the contest to be a fair test. Those twenty years gave a gain of fivefold in the proportion of prisoners of the Southern States, while the Northern States showed a gain of less than forty per cent. Single instances reveal it still more clearly. Mis- sissippi sprang from 67 to 1,158 criminals in a million inhabitants, and other States of the South show nearly as great a gain ; while New York and Massachusetts actually declined in their criminal percentage during that time, as did some other Northern States. The explanation is obvious. Before the war the negroes were slaves, and nearly all their offenses were punished by their mas- ters, so that the State had no occasion to imprison them. But now, from five to ten times as many blacks as whites, in proportion to their numbers, are found in the jails or chain-gangs of the South. 214 THE POPULAR SCIENCE MONTHLY. And when we remember that the greatest illiteracy is to be found in the former slave States, we- see that the increase of the criminal ratio in the South may not be due wholly to ignorance, in spite of census figures. The ignorance and the crime were both there be- fore the criminals were locked up and counted in the census. One might, indeed, claim that the lessened ignorance had much to do with revealing this criminal element and imprisoning it. And this brings us to our third cause of the increased ratio of crime. The gradual elevation in the standard of life, and the intervention of the courts in cases which were formerly decided by the bullet or the knife, occasions a rapid increase in the official number of criminals. Drunkenness, I suppose, was not a crime anywhere in our land half a century ago. Now drunkenness and disorderly conduct form one tenth of all the crime of the country. And naturally the restraint of these offenders will be most complete in the most orderly and educated parts of our land. Accordingly, we find that the ten educated States show a proportion of imprisonments for these offenses tenfold greater than the uneducated States do. The one has 2,865 and the other only 198 in a population three fourths as large. And the educated States record three times as many pris- oners as the uneducated States for assault and battery and simple assault. If any one wishes to prove from the census that educa- tion is a failure, he could find no stronger facts than these — a ten- fold larger share of drunkenness and a threefold larger share of violence in the States where men can read and write than in the States where they can not. But, of course, no one thinks that the South is more quiet, or- derly, and innocent than the North. No one believes that there was not a single case of drunkenness or disorder in all Alabama and Ar- kansas in 1880, and only a score of cases of assault, while Massachu- setts, with a less population, had 597 cases of drunkenness and dis- order and 337 cases of assault ; yet this is what the census tells us. The natural interpretation must be, that drunkenness and violence are not punished by imprisonment in certain States, while they are in others, and the States that punish least are most illiterate. This interpretation is amply confirmed by the census itself. Though education shows three times the violence that ignorance does, yet ignorance perpetrates three times as many murders as education, and that, too, while two or three of the educated States imprison the murderer for life, and so swell the number, and while the illit- erate States do not even think of arresting some murderers, and often acquit others who are most notoriously guilty. It was only last year that all the land heard that a certain Dr. McDow, a mar- ried man of Charleston, S. C, murdered a Captain Dawson, simply because he saved a girl whom the doctor was trying to ruin. No EDUCATION AND CRIME. 215 one denied the murder, yet the papers tell us that the doctor was triumphantly acquitted and honored by the society of the city as a hero, instead of being counted by the census as a criminal. And it is only in a high state of society that offenses against virtue cease to be either overlooked or avenged by violence. In this very State of South Carolina there are only four such offend- ers reported in prison, while Michigan has forty and Massachusetts over two hundred. The latter State, indeed, has more than all the illiterate States together. Yet, are we to think that Michigan is ten times as sinful as South Carolina, or that Massachusetts has more vice than all the ignorant States combined ? McDow's case shows that such vice exists, and how it is regarded. A clergyman of the South recently asserted in the Nation — and he has not been contradicted — that only a small minority of the colored women were chaste ; yet the census makes them far more virtuous than their white sisters of the North. We do, indeed, hear quite fre- quently of negroes being lynched for such offenses, but they obvi- ously do not count in the census. Therefore, though education may swell the list of criminals, there are reasons for thinking that more education and not less is what certain parts of our country need. They need more prison- ers. If more men were punished for drunkenness and violence, there would be less murder. If more murderers were executed instead of being lynched or lionized, there would be less violence. It is by checking the lesser offenses that the greater offenses are avoided, though the prisons are filled thereby. And as civiliza- tion improves in the South, no doubt the proportion of men in prison will increase, at least for the present ; and the whole country can not rise in its standard of moral conduct without increasing the law-breakers, especially while we have to assimi- late each year such a large and often lawless element from other lands. One of the results of raising the mass to a higher moral level is, that individuals here and there drop out ; and the higher we are raised the more will drop, and this will continue till those in- capable of self-control have disappeared. It is only among sav- ages — where there is no chance to drop, because all are on the ground — that we find no criminals or paupers. And Mr. Reece actually sighs for the " perfect order " found associated with the " densest ignorance " among the cave-dwelling Veddahs and other tribes. Possibly we might attain this " perfect order " if we would imitate the savages in leading a savage life. But that would be a pretty dear price to pay for such order as savages secure. Most of us prefer civilization with all its drawbacks. We pre- fer to see our country settled, though we know that jails will be 216 THE POPULAR SCIENCE MONTHLY. built and occupied. The very convenience of city life is paid for by added crime. The disorder that might be allowed in a wilder- ness among savages can not be tolerated in a crowded metropolis among civilized people. The ten States that have the largest cities punish fifty per cent more violence and sixty per cent more drunkenness than their share, though they have twenty per cent less than their proportion of murders. Petty crimes come from civilization, great crimes from barbarism. But among barbarians great crimes are called virtues, and petty crimes are unknown or unnoted. I think, then, we need not fear that universal education is to bring us universal crime. We want more and better education. Of course, it is not the mere ability to read and write that is to save a man from prison. He must learn self-control and acquire a loftier standard of life. Mr. Reece dwells much upon the fact that a large percentage of our criminals can read and write. But that does not prove that their education made them criminals. I dare say a still larger percentage of them can see, yet it was not their ability to see that made them criminals. The densest igno- rance may, like total blindness, keep men from crime ; but we do not propose to put out our eyes of either mind or body. We will have men learn to see better, morally and physically. It is im- perfect education that has brought men to prison, as we see from the constant relation of our criminal class to our illiterate classes. They may, indeed, have some sort of an education, but the vast majority of them are ignorant themselves, and have ignorant kindred and associates ; and to be ignorant amid the civilization of to-day is to be jealous and bitter and rebellious. The very fact that Mr. Reece cites to prove his thesis, that igno- rance is innocence and knowledge crime, disproves it most com- pletely. South Carolina, he says, has the highest percentage of illiteracy and the lowest of crime ; but, if he had taken one glance below the surface, he would have seen a fact far more " novel and threatening " than any he discovered. Out of the 626 criminals of South Carolina, 570 are black and only 56 are white. Why are there ten times as many blacks as whites in jail, when they constitute only three fifths of the population ? The only answer the census gives is in the fact that they are three times as illiter- ate as the whites. So that the very State summoned to prove that ignorance is exemption from crime, has ten elevenths of its crimi- nals from the most ignorant class in the country. But perhaps Mr. Reece thinks that their ignorance is not quite dense enough, as one in four can still write. They certainly have not yet reached the point where ignorance is bliss. THE AFFIRMATIVE SIDE OF AGNOSTICISM. 217 THE AFFIRMATIVE SIDE OF AGNOSTICISM. By JAMES A. SKTLTOK WITH LETTERS FROM HERBERT SPENCER, PROF. HUXLEY, AND DR. LYMAN ABBOTT. IN the sacred literature of the Christian Church a word appears that to its founder and to his immediate followers evidently had a deep significance, the nature of which was at least partially concealed from his later followers, and is still concealed from those of the present day, through admitted mistranslation. Standing on Mars' Hill and speaking to the men of Athens, Paul affirmed that in all things they were " too Godi-f earing." * Whereupon he proceeded to declare and make known unto them the God whom they worshiped as the Unknown or Agnostic God. In so doing he spoke of a God, the Lord of heaven and earth, who made the world and all things therein ; who dwelt not in temples made with hands ; who needed nothing, seeing he was the giver of life, breath, and all things ; who had made of one blood all nations of men; and who had determined the times before ap- pointed and the bounds of their habitation. He declared that they should seek the Lord if haply they might feel after him and find him, though he was constantly at hand, and the one in whom they lived and moved and had their being. He closed with a strongly put antithesis in which, without declaring divine con- demnation of their agnosticism, which he said God " winked at," and they might therefore tolerate, he urged them to obey the com- mand of God — "metanoein" — to practice metanosticism. This word has been translated to mean " repent." It is hardly suffi- cient to say that that translation is etymologically inadequate; the history of the Christian Church also, for eighteen centu- ries, proves it to be practically so. Paul evidently found in the word " metanoein " the open door of a temple in which a God- fearing worship might be exchanged for a God-loving worship. The history of his own life shows that his personal conversion was a metanostic process through which a defective external sight was exchanged for a clear insight, revealed to him as with a lightning-flash at midnight, wherein he instantly saw " the world and all things therein " in an entirely new aspect. The question, then, indirectly presented for the consideration of the entire Christian Church, in the following correspondence, is, Whether it should adopt the word actually used by Paul, with its large meaning, either alone, as a step forward, and to restore to the sacred record and to the working power of the Church the * The word he uses is " deisidaimonesterous," and includes the idea of devil-fearing.

CORRESPONDENCE. New York, November 20, 1889. Herbert Spencer, Esq. Dear Sir : I beg the privilege of presenting hereby, for your consideration and determination, a question of seemingly uni- versal importance, that has arisen in the course of our work in the Brooklyn Ethical Association. As far as possible I have sought to so present it as to limit your labors therein to yea, yea, or nay, nay. The question relates to the selection and adoption of words for general use in the new philosophy, and as substitutes for the words agnostic and agnosticism, to express the affirmative side of the agnostic conception. As a result of our experience of nearly two years in attempt- ing to popularize evolution views, we find that just there our greatest obstacle is to be found, and our time and labor are most occupied and consumed, and increasingly so as we approach the popular mass. The object of this communication is to propose as such affirma- tive substitutes the words metagnosticism and metagnostic, or metanosticism and metanostic, and to ask therefor your own ap- proval and also that of Prof. Huxley — in concert, if possible. My own view is that the new or substitute words involve no surrender or concession, but, on the contrary, if adopted would mark an advance in the nomenclature of the agnostic phi- losophy. The accompanying statement was made by me as part of the discussion following the reading of the essay of Dr. Lewis G. Janes, on The Scope and Principles of the Evolution Philosophy, the first of the current series of the Brooklyn Ethical Associa- tion, on the evening of October 13, 1889, and it will explain itself. I also hand you herewith a list of words and their definitions, derived or derivable from the Greek verbs gignoslcein and noein, in composition with the preposition meta, the imperative form of which was used, according to the Greek Testament, by John the Baptist and Jesus Christ, in that passage in which they are made in the Douay Bible to say, "Do penance, for the kingdom of heaven is at hand," following the Latin Yulgate ; and in King James's and later English versions, " Eepent, for the kingdom of heaven is at hand." THE AFFIRMATIVE SIDE OF AGNOSTICISM. 219 These definitions of these words were prepared more than a year ago, at the special written request of Rev. Lyman Abbott, D. D., the pastor of Plymouth Church, Brooklyn ; and the list is a copy of the first rough draft or study made in compliance with that request, but, for reasons unnecessary to explain here, has not yet been presented to him. For what use these definitions were intended by him I am neither authorized nor prepared to posi- tively state. Dr. Abbott is in special charge of theology, liturgies, and ecclesiastical history, as editorial contributor, under the chief editorship of Prof. William D. Whitney, in the preparation of The Century Dictionary, which is an encyclopedic dictionary of the English language, now in course of publication by the Cent- ury Company, the first volume of which now lies before me. . . . In Volume I the words agnostic and agnosticism are defined at length, with references to Huxley, Romanes, and Cobbe, and to the source of the suggestion of the same by Prof. Huxley in the mention by St. Paul of the altar he had seen erected by the Athe- nians to the Unknown God.* As I have previously informed you, early in his pastorship of Plymouth Church, Dr. Abbott declared his belief in the evolution philosophy, and his high sense of the value of its co-operation in the religious work of the future. He is also the editor of The Christian Union, the leading liberal religious newspaper in Amer- ica. His position as such may be stated to be evangelical-liberal, or conservative-progressive, with the promise of moving faster and further, as soon as circumstances permit. Practically, things are in a ferment in all religious denominations in America at this time ; or, to speak more accurately, we seem to be entering a new constructive period, and one which furnishes agnosticism and evolution their great religious opportunity. In the statement referred to I have used the words meta- gnostic and metagnosticism to preserve or make parallelism in form with the words agnostic and agnosticism, to which the public eye and ear have now become accustomed, and to the bet- ter present the expressive antithesis involved therein. I am, however, fully aware that a word-form and meaning directly de- rived from the word metanoeite (metanoeo), which is the actual word placed in the mouth of Christ by and through the Greek original, would have certain great advantages. Prominent among them would be the ever-present evidence it would furnish that in the gospel, as actually preached by Christ and his immediate con- temporaries and handed down to us, so far as we know it, the human mind was to occupy the leading place, to be elevated, and * The authority of the Century Dictionary for this erroneous explanation of Prof. Hux- ley's derivation of the word " agnostic " (see letter from Prof. Huxley) was the New Eng- lish Dictionary. 220 THE POPULAR SCIENCE MONTHLY. not degraded and disfranchised, as it lias been by bis alleged fol- lowers for ages past. Not only in this respect, as it seems to me, would the adoption of such a word bring science and philosophy into harmony with the true religion of Christ and nature, but it would also compel the beginning of a change in organized Chris- tianity that would eventually bring it into complete harmony with them. Whether the best word is metagnostic, metanostic, meta- gnosticism, or metanosticism, or some other form derivable di- rectly or more remotely from the root nous, mind, is to me a ques- tion of minor importance. I would select that which, on the whole, is the truest and best, for the purpose of bringing about the desired reconciliation of religious with other forms of truth, even if it were necessary to manufacture the form for the occa- sion; and this, it seems to me, we are at liberty to do, since, strange as it may seem, while we have in our language and in frequent use all the other words derived from the kindred Greek words, the most important words of all, and the supreme words of the religion of the English race (metanoeite and metanoia), have never, apparently, up to this time, been transferred to or adopted into the English language. The suggestion is based upon the proposition that the words to be adopted do and shall express, cover, or include the affirma- tive side of the terms agnostic and agnosticism. The selection of the proper forms I leave entirely to you, in co-operation with Prof. Huxley, if you approve the suggestion and think the mat- ter worthy your and his attention. Certainly it must, it seems to me, be considered a desirable thing to find words of affirmative import to designate the affirma- tive meaning hidden under the terms in present use, since it must seemingly tend to foreclose further argument and confusion on that branch of the subject. I inclose copies of these papers to be addressed and forwarded to Prof. Huxley, if that course meets your approval. My own plan would be, on receipt of the approval of yourself and Prof. Huxley, to bring the matter before the public, through our Association, at one of the meetings of the series now well com- menced for the season, through The Popular Science Monthly, and by other means within my present reach. I am confident that recognition in the Century Dictionary would follow, and that a great impulse would be given to the new philosophy, to what would practically be a new or reformed Christian religion, m harmony with human intelligence and progress, with the ex- press word and thought of the founder of Christianity, and cal- culated to combine them in the interests of the world and the race. Very respectfully yours, James A. Skilton. THE AFFIRMATIVE SIDE OF AGNOSTICISM. 221 a The "list" referred to included the words meta(g)nostic, nouns and adjective, meta(g)nosticism, meta(g)noiology, and meta(g)no- sis. The definitions given were made approximately parallel with the definitions of the words diagnostic, prognostic, diagno- sis, prognosis, etc., as found in Webster, and need not he here presented. Monday, November 25th. P. S. — The foregoing letter was complete on Saturday last. On Sunday, the 24th inst., by a coincidence that seems to me not to be a mere coincidence, Dr. Abbott, without any knowledge of this correspondence or my intentions, took for his subject the sermon of Paul on Mars' Hill, for the purpose of dealing with the " new doctrine " and " new thing " involved in the " new theology " now agitating the American churches. He referred to your position and that of Prof. Huxley, quoted from your writings, and prac- tically placed himself not only in line with agnosticism as ex- plained by you, but so near to the position I have given him in these pages that the next step must have brought out the new word. His expressed thought implied it, and I had prepared myself to hear it, when he suddenly brought his sermon to a close. I feel myself, therefore, once more justified in my statements, and am all the more anxious to use, or rather to have you use, the present opportunity. I will ask him to print the sermon, that I may send it to you in confirmation.* J. A. S. STATEMENT. Dr. Janes having unexpectedly and without suggestion of mine used my name in connection with the term "metagnos- ticism," I feel compelled to make my use of it as clear as possible at once, without waiting another occasion. The doctor chooses his words with exceeding skill and care. He says that he will endeavor, in defining philosophical agnos- ticism, to show that " in every department of scientific, historical, and true philosophic investigation, indeed, it is consistent and coincident with the meta-gnosticism of his friend Mr. Skilton." \ As so limited — to the definition of philosophical agnosticism — the statement and the subsequent showing are both entirely satisfactory. But the limitation is not so. As adopted and used by me, the term meta-gnosticism has a much larger meaning, and has an important bearing not only upon science, history, and philosophy, but also upon and in re- * The substance of the sermon is embodied in an article in the Forum for April, 1890. f For a discussion of meta(g)nosticism in relation to the evolution of society, see Evo- lution — Popular Lectures and Discussions, before the Brooklyn Ethical Association, pp. 216-227. 222 THE POPULAR SCIENCE MONTHLY. ligion, meaning the religion of our civilization, as well as the religion of evolution and the future. The evidence is abundant that even in the domains of science and philosophy the word agnosticism does not and can not express in full the idea or system for which it stands representative. Mr. Huxley, the inventor of it, is, as we all know, in a state of con- stant warfare over it ; and as to Mr. Spencer, it is sufficient to refer to his controversy with Frederic Harrison and his " x u " as the appropriate symbol " for the religion of the Infinite Unknow- able." With both of these men — the acknowledged leaders among agnostics — and with all their followers, the trouble is that at present they are compelled to seek to accomplish the practically impossible by attempting to read a positive and affirmative mean- ing into a word that is and can be only indefinite and negative. And the words meta-gnosticism and meta-gnostic are proposed for the purpose of meeting precisely that difficulty, and for the reason that they are positive and affirmative. Mr. Huxley really found the word agnostic, or its root, already in use in the Greek language, and borrowed and used it for the want of a better one, little thinking, doubtless, how important it would become. It is believed that the time has now arrived for importing another word, cognate in origin and affirmative in meaning, into our language, if it be found by competent authority to meet the requirements of the case. In his essay entitled Retrogressive Religion, in reply to Harri- son, Spencer says (p. 68, Appletons' edition) : " I might enlarge on the fact that, though the name Agnos- ticism fitly expresses the confessed inability to know or conceive the nature of the Power manifested through phenomena, it fails to indicate the confessed ability to recognize the existence of that Power as of all things the most certain. I might make clear the contrast between that Comtean Agnosticism which says that ( theology and ontology alike end in the Everlasting Wo with which Science confronts all their assertions/ and the Agnosticism set forth in First Principles, which, along with its denials, em- phatically utters an Everlasting Yes. And I might show in detail that Mr. Harrison is wrong in implying that Agnosticism, as I hold it, is anything more than silent with respect to the question of personality ; since, though the attributes of person- ality, as we know it, can not be conceived by us as attributes of the Unknown Cause of things, yet ' duty requires us neither to affirm nor deny personality/ but 'to submit ourselves with all humility to the established limits of our intelligence ' in the con- viction that the choice is not 'between personality and some- thing lower than personality/ but e between personality and some- THE AFFIRMATIVE SIDE OF AGNOSTICISM. 223 thing higher/ and that ' the Ultimate Power is no more repre- sentable in terms of human consciousness than human conscious- ness is representable in terms of a plant's functions/ " And again (p. 6Q, id.) : "Whereas, in common with his teacher Sir William Hamilton, Dean Mansel alleged that our consciousness of the Ab- solute is merely ' a negation of conceivability ' ; I have, over a space of ten pages, contended that our consciousness of the Abso- lute is not negative but positive, and is the one indestructible ele- ment of consciousness ' which persists at all times, under all cir- cumstances, and can not cease until consciousness ceases ' — have argued that while the Power which transcends phenomena can not be brought within the forms of our finite thought, yet that, as be- ing a necessary datum of every thought, belief in its existence has, among our beliefs, the highest validity of any : is not, as Sir W. Hamilton alleges, a belief with which we are supernaturally ' inspired/ but is a normal deliverance of consciousness." These quotations are sufficient to show that, as he holds it, there is a positive and affirmative side to the doctrine of the Unknowable, or to agnosticism, as taught by Mr. Spencer ; and also that there is occasion for a word or words to express it. In his article Agnosticism, published in The Popular Science Monthly for April, 1889, Prof. Huxley says : " Agnosticism, in fact, is not a creed, but a method, the essence of which lies in the rigorous application of a single principle. That principle is of great antiquity ; it is as old as Socrates ; as old as the writer who said, 'Try all things, hold fast by that which is good ' ; it is the foundation of the Reformation, which simply illustrated the axiom that every man should be able to give a reason for the faith that is in him ; it is the great principle of Descartes ; it is the fundamental axiom of modern science. Positively, the principle may be expressed : In matters of the in- tellect, follow your reason as far as it will take you, without regard to any other consideration. And negatively : In matters of the intellect, do not pretend that conclusions are certain which are not demonstrated or demonstrable. That I take to be the agnostic faith, which, if a man keep whole and undefiled, he shall not be ashamed to look the universe in the face, whatever the future may have in store for him. " The results of the working out of the agnostic principle will vary according to individual knowledge and capacity, and accord- ing to the general condition of science. That which is unproved to-day may be proved, by the help of new discoveries, to-morrow. The only negative fixed points will be those negations which flow from the demonstrable limitation of our faculties. And the only obligation accepted is to have the mind always open to con- viction." 224 THE POPULAR SCIENCE MONTHLY. In view of such utterances — and of many similar ones in other writings of both Spencer and Huxley — it seems that a positive and affirmative word, or set of words, capable of expressing the agnostic idea, if to be found or framed, would not only be appli- cable, but would be acceptable to them and fit for the system of thought with which the essay of the evening is concerned. The words proposed come from the same root as the words gnostic, agnostic, prognostic, and diagnostic. The root is verbal and affirmative. It means to know ; and with the prefix meta, means to know beyond. The noun means beyond-knowledge. Beyond-knowledge may be knowledge "be- yond the sphere of sense," and correspond to Spencer's definition of religion, or, as you will, it may refer to all knowledge beyond mere sense-perception, and so include all human knowledge that exceeds that of the brute animal and is derived from or limited by the senses. As for myself, I prefer the total meaning : for then, as the civil engineer uses his base-line and two known angles to measure distances and relations of things beyond the river where he can not go with his tape-line, and the astronomer the distances, actual and relative, of the heavenly bodies, so we may use our actual hither-knowledge for the purpose of dealing with the field of beyond-knowledge — or of the Unknowable — where the senses can give us no direct aid. As to the appropriateness of the adoption of the proposed words into the English nomenclature of religion, the evidence at hand is still more authoritative and conclusive than in the case of science and philosophy. In his preceding essay — Religion : A Retrospect and a Prospect — Mr. Spencer begins with these words : "Unlike the ordinary consciousness, the religious conscious- ness is concerned with that which lies beyond the sphere of sense. * A brute thinks only of things which can be touched, seen, heard, tasted, etc. ; and the like is true of the untaught child, the deaf- mute, and the lowest savage. But the developing man has thoughts about existences which he regards as usually intangible, inaudible, invisible ; and yet which he regards as operative upon him." If you ask the source from which the proposed words are de- rived, the reply is that, as to the second form, it is found in the New Testament, and is the supreme word in the messages of John the Baptist, of St. Paul, of Jesus Christ, and of the gospel gener- ally, wherein it is believed truly to have the precise meaning — as shown by the context — of the proposed English word or words under discussion ; and that, as to the first form, it is constructed by throwing out the prefix — a — from the word agnosticism, and substituting the prefix — meta. Prof. Huxley, the inventor of the word agnostic, is said to THE AFFIRMATIVE SIDE OF AGNOSTICISM. 225 have derived it from St. Paul's mention of the Unknown or Ag- nostic God. The word now suggested is derived from the substi- tute proposed by St. Paul at the same time. While St. Paul did not advise the Athenians to erect an altar to the metanostic God in place of the altar they had erected to the Agnostic God, he used the word metanoein, and he thereby clearly advocated the practice of what we may properly call metanosticism as the alter- native and substitute for agnosticism, in connection with religion and its observances. This he did after expressly declaring the absence of any divine condemnation of their agnosticism, which God is said to have " winked at " or overlooked. The strong and suggestive antithesis made use of by St. Paul has been lost in the translations of the language employed by him on that occasion ; but there is no time to enlarge, here and now, upon the fraudu- lent travesty practiced upon mankind for ages by the Church in translating the original word so used to mean " do penance " and " repent." I content myself with asking, What would be the consequences of the candid, common, and proper acceptance and use, through- out the civilized world, of such a word to express the central thought of the science, the philosophy, and the religion of our age and of the ages to come, sanctioned by the high priests of each of these departments of thought ? I have only a word to add : Without committing this Associa- tion, as its corresponding secretary, or otherwise, or any other person but myself, to the proposition, it is my purpose to submit the question of the adoption of the words meta-gnostic and meta- gnosticism, or metanostic and metanosticism, as affirmative sub- stitutes for the words agnostic or agnosticism, to Mr. Spencer and Mr. Huxley, in the hope that, as leaders in modern agnostic thought, they will see their way clear to their adoption, and thereby supply a link to unite science, philosophy, and a true Christian religion in behalf of humanity and future ages. And when their replies are received — if so be — they will be communicated to this Association for its further consideration, and possibly for its co-operative action. LETTER OF HERBERT SPENCER. 64 Avenue Road, Regent's Park, London, N. W., December 22, 1889. My Dear Sir : I have to thank you for the volume of Evolu- tion lectures, which I received recently. I presumed that they would eventually be bound together, and that you would kindly send me a copy. This, of course, I shall like to keep. Will you excuse me if I do not go into the matters raised by your late letters ? I have been made so ill by over-excitement that until Wednesday last I had not been out for more than a 226 THE POPULAR SCIENCE MONTHLY. month, and, though I am now better, I must avoid every mental tax, however small. I did not receive the journal which you named in your last, containing some matter respecting Dr. Abbott's address (I think it was). Very truly yours, Herbert Spencer. J. A. Skilton, Esq. LETTER OF PROFESSOR HUXLEY. Eastbourne, England, December 10, 1889. Dear Sir : I have read the papers which accompanied your letter of the 25th of November with much attention ; but, I regret to say, with the result that I can discover no good ground for the change of nomenclature which you propose. Permit me to trouble you with my reasons for that conclusion : The term " Agnostic " was not suggested by the passage in the " Acts of the Apostles " in which Paul speaks of an inscription to the " Unknown God" (dyvwo-ro) 0ehio, many a time, before starting to drive home the cows from a woods-pasture— in which they might easily have wandered out of sight— have I looked about in the angle of a gate-post, or under the cap of a board fence, in whose shady cor- ners the daddy-long-legs often lurk, and, having found one of the torpid beings, seized him by one leg and held him as I repeated our prescribed incantation: " Gran'-daddy, gran'-daddy-long-legs, Tell me where my cows are, or I'll kill you ! " Naturally, the spider, discomfited by his bondage, would lift one of his legs, and the cows, it was said, would be found in the direction indicated by this uplifted leg. I don't think that we children really believed that this indication would always hold good, or that we even paid very much attention to the path so designated; but, as I remember it, we felt it to be the proper thing to do to consult our oracle, and I doubt not the ceremony sent us off on our evening quest with better courage. The same custom is reported from different parts of New York State, Indiana, Illi- nois, and Tennessee. The incantation varies somewhat with the locality. In Tennessee it is simply — "Daddy-long-legs, which way are my cows? " An old physician writes me that " in western New York, sixty years ago, the verses ran — ' Grandfather gray-beard, Tell me where my cows are, or I'll kill yon ! ' After this had been repeated several times in a drawling mono- tone, lengthening out the syllables e gray ' and ' kill/ if the captive lifted a leg and held it suspended for a moment, he was faithfully released; otherwise, he was ruthlessly killed." Certainly there must be some occult connection between these malodorous arach- nids and the cows, for in Tennessee the farmer-boys tell you that killing a grand-daddy-long-legs will make the cows go dry. In the pine woodlands of southern Louisiana, so a New Or- leans lady writes, there are found little mounds of mud, with quite a large opening in the center of each — probably crayfish- holes. Negro nurses caution the children under their charge never to touch these tiny mounds, believing that they are snake- holes, and that any meddling will lead the snake which lives there to leave his burrow at night and come and bite the offender. In western New York, forty or fifty years ago, the panacea for dirt or other foreign substances in the eye was what the children called " crabs' eye-stones," the two calcareous, lenticular concre- tions found between the stomach-walls of the crayfish. In these ANIMAL AND PLANT LORE. 251 gastroliths is stored away for the molting season a reservoir of material to form a new shell. The children, having no knowledge of the real use of the gastroliths, believe them to be a providen- tial arrangement for the relief of pain in man, and for genera- tions this belief has been entertained by adults, for the gastroliths are really the commercial eye-stones that were once widely used to remove any irritating particle from the eye ; but the practice is now condemned by physicians. It is scarcely possible that there is any power sui generis in these neat little bodies which an arti- ficial f ac-simile would not possess. Very likely this widely credited virtue of the eye-stones is a result of the varied use in medicine of the European crayfish in past ages. Powdered gastroliths were formerly used in Europe as an antacid, while Pliny cites a score of prescriptions in which the crushed animal, the bruised flesh, the juice expressed from it, macerations in various liquids, or the incinerated and pulverized shell were recommended for all sorts of purposes from antidoting poisons to allaying fevers. Some time ago I heard a very notable New England house- keeper ask a young girl, who was assisting her by preparing a lob- ster for the tea-table, if she had been careful to remove the "lady." In answer to my inquiry as to what was meant by this, I was told that there is a part known as the " lady" — a small, greenish object inside the lobster, which is a perfect image of a tiny woman seated in a chair — and that this part of the animal is deadly poison, and should therefore always be carefully removed in preparing the flesh for the table. I find that, in general throughout Massachu- setts, this name of " lady " is given to the stomach, which may be imagined to bear a remote resemblance to a miniature woman. Since the lobster is a notorious sea-scavenger, the contents of the stomach would probably be very undesirable for food, though why this stigma of being poisonous should need to be attached to the hard, calcareous-toothed, inedible stomach-walls it would not be easy to tell. In central New Hampshire the name " lady " is some- times applied to the intestine — the dark tube running lengthwise of the lobster's body — and this is considered poisonous. In Cam- bridge, Mass., an intelligent fish-dealer, on being questioned as to the nature and position of the " lady " in the lobster, designated by that name the edible ovary popularly called the " coral." An in- genious theory has been propounded to me to explain the cause of the so-called " lady " being dangerously poisonous. The reasoning was about as follows: "You know that lobsters must be alive when they are dropped into hot water to be cooked. If you should let them die before they are cooked, they would be poison and not fit to eat, and I suppose that the poison, which before they are cooked is scattered everywhere through its whole body, all goes into the " lady " while the lobster is being boiled." 252 THE POPULAR SCIENCE MONTHLY. In Louisville, Ky., the children are afraid to kill the common sow-bug (Oniscus), which they call " mad dog," believing that the disagreeable-looking little crustacean can give one the hydropho- bia. In my own mind there is a faint recollection of having heard that a poultice made from these creatures possessed great remedial powers of some kind. The genuineness of my half-ob- literated reminiscence of the therapeutical value of the sow-bug lately received an unexpected confirmation from the pages of a copy of The Complete English Dispensatory, by John Quincy, printed not far from the middle of the eighteenth century. This rare old book, which had long lain among the unconsidered rub- bish in the garret of an old-fashioned New Hampshire farm-house, contains a vast amount of curious medical lore. Not a few of the remedies which it describes are so alchemistically compounded as to seem to have come straight down from the later adepts in that pseudo-science. Other preparations, again, are unpleasant enough in their composition to satisfy an ancient Roman or a modern Chinese practitioner, as witness the following (by no means one of the most objectionable) : " Expressio Millipedum Simplex (A Simple Expression of Millipedes). — Take live millipedes and white sugar ana § iij, beat them well together in a marble mortar, and pour upon them lb. j of white wine, which strain out again by hard squeezing." This formula is quoted by Quincy from Dr. Fuller's Pharma- copoeia Extemporanea as a diuretic. Among other synonyms for " millipedes " as here used, Quincy gives " sows " and " onisci." I find that Pliny recommends " millipedes " (which the editor of the translation of the Natural History in Bohn's series identifies with onisci) for pains in the ear. Holland is quoted in a foot-note in the above-mentioned translation, as sanctioning the use of wood- lice (sow-bugs) for pains in the ears ; and the editor also states that English school-boys swallow them alive, and that old women advise their use in consumptive cases. Perhaps every one has noticed the club-shaped, whitish mass at the proximal end of a freshly pulled human hair. This root of the hair, together with the attached connective tissue and adipose material, is often absent, from the fact that the hair frequently breaks off near the opening of the follicle, instead of coming out entire from the interior of the latter. So it has come about that the root of the hair is in different localities mistaken for an ani- mal parasite, called a hair-eater. In many places in Maine and Massachusetts, if these bulbs are noticed among combings, people will say that the scalp is infested with hair-eaters, and that the latter must be killed, or they will certainly ruin the hair. NATURAL AND ARTIFICIAL CEMENTS. 253 NATURAL AND ARTIFICIAL CEMENTS. By Prof. LA ROY F. GRIFFIN. THE cements now in the market are of two kinds: natural, made directly from stone ; and artificial, commonly called Portland cement. The manufacture of the former consists simply in burning and grinding the cement stone, a magnesian limestone containing about fifteen per cent of silica and a little silicate of alumina. The burning drives off the small amount of combined water and all the carbon dioxide from the stone, leaving the lime and magnesia as oxides, while the grinding to a powder puts it into the best possible condition for mixing with sand and gravel, and moistening to form a mortar. Artificial cement consists of about sixty-two per cent of lime mixed with silica and silicate of alumina in nearly the same proportions as' those found in the cement stone, and it is free from magnesia. This seems to be the whole difference in its constitution. In use, the artificial cement sets rapidly and attains maximum hardness in a comparatively short time ; the natural cement hardens rather slowly and reaches its maximum hardness only after a long period of exposure to the air. The increasing use of cement in modern construction, either alone or more commonly as mixed with sand and gravel, demands that the qualities of the different kinds, and the means of testing, both roughly and accurately, should be generally understood. The foundations of all important structures, in situations where they can not rest directly upon solid rock, owe their strength to cement. They are usually made of concrete, cement mixed with sand or gravel, and they are often strengthened by iron beams so as to bind the whole into one continuous mass. Tunnels under rivers, sewers, cable trenches, and all the numerous subways of our large cities, are either concrete or masonry laid in cement mortar. Their strength, again, is the strength of the cement used. And even the piers of most of the large bridges are now made in part or wholly of concrete. Oftentimes, even the walls of stone and brick buildings are rendered more secure by being laid up with mortar of which cement forms a large ingredient. Used for so many purposes, the necessity of uniform quality, and proper knowledge of the quality of the cement used, become plain. Before examining the methods of testing now employed and comparing the results, the process of hardening needs to be com- prehended. Some things are not yet quite clear in it, but it is certainly in the main a chemical process. Mixed with water, the lime and magnesia of the cement unite to form a hydrate, and it 254 THE POPULAR SCIENCE MONTHLY. is probable that the silicates also recombine with some of the water. This is the first step, and produces the so-called setting. It is best passed through while the cement is exposed to the air, and is the reason why cement mixtures must be used as soon as moistened. But, this now complete, a more complex process is set up. The moistened cement brought in contact with the air, or exposed to water, at once begins to absorb carbon dioxide, for all ordinary air contains the gas, and most water holds it in solution. The gas unites with the lime to form a carbonate again, and this goes on until the whole of the lime is turned back to limestone. The same change occurs in the magnesia, but in this the action proceeds more slowly. With a pure lime cement this action is probably nearly complete at the end of a few months ; but, with a cement containing magnesia, it will continue for many years. The strength of the cement increases so long as the change con- tinues. So a Portland cement will develop its full strength in a few months, while our natural cements will not for years, and, so long as it continues, the structure improves. Rough testing of cement, so as to enable a workman to get a crude and imperfect idea of its value, is easy. Enough of the pure cement should be taken to make a ball an inch in diameter and mixed with just sufficient water to make it mold readily and be rolled into a ball. Then it should be exposed to the air and left for two hours. At the end of that time it should be set ; then it should be put into water and left. It should grow gradually harder, and should show no signs of cracking or crumbling, even when left for ten days. Any cement that does not endure this test is not of sufficiently good quality to make satisfactory structures ; any cement that stands this properly will be gener- ally satisfactory if properly used. In determining how to construct a building, a series of tests is often required that shall show tensile, breaking, twisting, and crushing strength, and also adhesion of the materials used for mortar. No one of these can be dispensed with, since material that will endure one satisfactorily will often fail utterly in an- other, and hence prove worthless for the use desired ; but for gen- eral purposes the test of cement which is the most valuable is that which determines its tensile strength. Comparative tests of this show the value of cements from different sources better than any other one test. To make an accurate test of any lot of cement, great care is necessary in selecting and manipulating the samples. The test sample ought not to be taken from a single package, but from several in equal quantities and thoroughly mixed. The sample must also be carefully protected from air and moisture until the test is made. When used, it must be molded with just the right NATURAL AND ARTIFICIAL CEMENTS. 255 Fig. 1 amount of water to render it plastic. Too small an amount will leave some particles dry; too large an amount will gather in masses, will evaporate, leaving pores, and will give too small results. The test is now commonly made by molding a bri- quette of a form approved by engineers, as shown in Fig. 1, which is drawn of one third actual size. The mold is a clamp of metal exactly one inch in thickness and exactly one inch across at R. This makes the area of the smallest place exactly an inch. The moistened cement is carefully placed in the mold with a spatula and pressed enough to ren- der the whole mass homogeneous. It is left in the mold until it can be removed by opening the mold, and then it is exposed to the air for exactly twenty- four hours, after which it is put into water and allowed to rest there until the test is made. ■ The length of time depends upon the purpose of the test. In order to make certain that all the cement produced is of a uniform quality, seven days is suf- ficient. Such a test is made of every lot shipped by the Milwaukee Cement Company, and probably by all other reliable manufacturers. If the test is to determine the ultimate strength developed or to compare cements from different sources, then a series of tests should be made by break- ing " briquettes " made at the same time but left in water for different periods. The reason is, that a quick-setting cement 'will develop its full strength in a short time, and if the test is made at the end of that time it might show a greater tensile strength than another one slow in setting, even when the latter would ultimately have sev- eral times its strength. The test can be made in any form of testing machine, though one in which the test is applied by uniformly increasing the strain, as by running shot into a bucket upon the end of a lever, gives the most accurate results ; but the briquette should be held in a clutch that presses accu- rately upon the sides, as shown in Fig. 2. This applies the tension equally, and gives a very ac- curate test. A long series of these were made by Mr. D. J. Whettemore, C. E., at Milwaukee in 1874, in which seventeen native cements showed an average tensile strength at the end of seven days of 80 &• pounds. The lowest of these broke at 38 pounds, while the highest sustained 139f pounds. Later tests made in Fig. 2. z 5 6 THE POPULAR SCIENCE MONTHLY, the same way have shown that these were unreliable as final tests of strength, because the briquettes had not hardened suffi- ciently, and the table would place inferior cements above those of much greater strength because the inferior develops its ulti- mate strength much sooner. But a comparative test of the same cements when mixed with sand in equal parts was also made, and is of very great value and probably perfectly reliable, for the tests were then made at the end of ninety days, so giving the slow-setting cements time to develop their strength. Thus the one which in the test applied to clear cement broke at 38 pounds now sustained 152i pounds, an increase of four hun- dred per cent ; while the one that was the strongest at the end of seven days now broke at 204|- pounds, an increase of only fifty-four per cent. The one that showed the greatest tensile strength of all, at the end of ninety days, the Milwaukee cement, 290 pounds, broke at only 96 at the end of seven days. An experiment made with a briquette taken at random, that had been made six months and exposed to the air at least half that time, strikingly showed the same fact, for it broke only under a strain of 636 pounds. This test was made simply to show the writer the method of using the testing machine. The United States Government had a series of tests made a few years ago, using the cements commonly sold in the West, and giving in each case the mean result of seventy -five tests. The table is so interesting that we give it entire. Tensile Strength of Pur.e Cements, each Test given "being the Mean Result from Seventy-five Specimens, Thirty and Sixty Days. Thirty days.

A large number of tests has been made to de- termine the weight required to crush a cube one inch in each dimension. When mixed with sand in equal proportions, the best cements will sustain a crushing weight of upward of a ton, the specimen having been allowed to harden for ninety days, while the poorest do not sustain quite half a ton, and even when mixed with three parts sand to one of the cement, the Milwaukee, which tests have shown the best, sustains over eleven hundred pounds. These tests show conclusively that structures well built of mixed cement SKETCH OF THE ODOR SCHWANN. 257 and sand or coarse gravel will sustain any reasonable weight without danger of yielding. Little needs to be added upon adhesion. Many attempts have been made to determine the adhesive strength of various cements, usually without success — not because they do not hold properly, but because they hold until the brick or stone to which they have been applied is ruptured before the cement is separated from its surface. This shows that the adhesion is always sufficient for all uses, and this seems to be true of all our native cements. Their use, therefore, mixed with mortar adds greatly to the strength of the structure. All these qualities of cement warrant its continual and in- creased use, particularly of all the better grades. Probably the English Portland is the best of all, but its cost is so much be- yond that of our native cements as to warrant using them in its place in somewhat larger proportion in all places where time can be allowed for the hardening. » » SKETCH OF THEODOR SCHWANN. By M. LEON FREDERICQ. ON the 23d of January, 1878, was celebrated at the University of Lie'ge, by the scientific men of Belgium and others rep- resenting neighboring European states and more distant coun- tries, the fortieth anniversary of the professorship of Theodor Schwann. Men of all nations joined, by their presence or by letter, in honoring the man who, as the founder of the cell theory, had showed that all the varied and complex manifestations of Nature are one in kind, and had given a new direction to physio- logical research. The object of this demonstration, Theodor Schwann, was born on the 7th of December, 1810, at Neuss, near Dusseldorff, in Rhenish Prussia, and died in Lie'ge, in January, 1882. His father and grandfather were goldsmiths ; but the father, after Theodor was born, established a printing-office — himself, with the aid of an artisan, constructing the first press — which has become one of the most prosperous concerns of the kind in the Rhenish country. From it was issued the memorial volume published in 1879 in honor of Theodor Schwann. The youth inherited from his father a decided taste for manual occupations, which afterward proved of great assistance to him in his laboratory work. While still a child he used to spend his play-hours in making miniature instruments of physics with the most primitive materials. From the primary school he went into VOL. XXXVII. — 20 25 8 THE POPULAR SCIENCE MONTHLY. the humanitarian courses in the pro-gymnasium of his native village, and thence, for the completion of his studies, to the Jesuit College at Cologne. His lively intelligence and assiduity attracted the attention of all his teachers. He exhibited a marked predilection for mathematical and scientific studies, es- pecially in physics. He was still undecided as to the career he should choose, when he enrolled himself, in October, 1829, in the class in philosophy at Bonn. His family were deeply religious, and would have been glad to see him become a clergyman like his elder brother Peter, who died in 1881, Professor of Theology and honorary canon at Frauenburg. Therefore he began with a mixed course, including metaphysical and logical studies, along with those in mathematics and science. The latter branches in the end absorbed all his at- tention, and he decided to study medicine. He became the pupil of the anatomist and physiologist Jo- hann Muller, and that fixed his destiny. Muller, with a full appreciation of Schwann's abilities, made him an associate in his labors, and they experimented together on the motor and sensitive roots of the spinal nerves, and on the coagulation of the blood. Having passed the philosophical and scientific examinations at Bonn, Schwann went to Wurzburg, where he passed three semes- ters, and then removed to Berlin to complete his studies and go through his final examinations. He found Muller here again, as Professor of Anatomy and Physiology, and under his direction performed the investigation on the necessity of oxygen to the development of the embryo in the hen's egg, on which was based his inaugural dissertation on receiving the degree of doctor of medicine. Muller, insisting upon Schwann's following a scientific career, had him appointed in 1834 aid at the Anatomical Museum, of which he was director. The position was an extremely modest one, and not at all pleasant. The late Director of the Berlin Mu- seum, Peters, speaks of having seen Schwann at work for whole days scraping the fins of a giant ray while preparing its skeleton ; and many of the specimens in the zoological collections bear wit- ness to the conscientious care with which he performed this mo- notonous work. The five years which Schwann spent here with Muller were a period of intense application, marked by a succes- sion of discoveries. All the great works which illustrate his name date from this epoch. A characteristic portrait of Schwann as he appeared at this time has been drawn by Henle, who passed several years under the same roof with him. He says : " He was a man of stature below the medium, with a beardless face, an almost infantine and always smiling expression, smooth, dark-brown hair, wearing a SKETCH OF THE OD OR SCHWANN. 259 fur-trimmed dressing-gown, living in a poorly lighted room on the second floor of a restaurant which was not even of the second class. He would pass whole days there without going out, with a few rare books around him and numerous glass vessels, retorts, vials, and tubes, simple apparatus which he made himself. Or I go in thought to the dark and fusty halls of the Anatomical Insti- tute, where we used to work till nightfall by the side of our excel- lent chief, Johann Muller. We took our dinner in the evening, after the English fashion, so that we might enjoy more of the ad- vantage of daylight. Our porter's wife furnished the meat, we the wine and wit. Those were happy days which the present genera- tion might envy us ; happy days when the first good microscopes had been sent out from the shops of Plossi at Vienna, or of Pis- tor and Schick at Berlin, which we paid for by exercising a stu- dent's economies ; happy days, when it was still possible to make a first-class discovery by scraping an animal' membrane with the nail or cutting it with the scalpel." Muller had at that time be- gun the publication of his great treatise on physiology, a work of scientific criticism into which he admitted nothing as true that had not been verified by himself or by his assistants under his eyes. Schwann, at his instigation, undertook a number of physi- ological and microscopical researches for this work. He exam- ined the texture of the voluntary muscles ; pointed out a method of isolating the primary fibers, and demonstrated the origin of the transverse striae of their primitive bundles. He sought for the terminations of the nerves in the muscles, without being able to discover them. He did not accept the ansated termination, which was generally believed in then, but has now been dis- proved. He first determined the existence of the proper walls of the capillary vessels, and came very near discovering their endo- thelium. He demonstrated, by physiological experiments with cold water, the muscular contractibility of the arteries. He dis- covered in the mesentery of the frog and the tail of the tadpole the division of the primitive fiber of the nerves, an observation then without precedent. He first proved, by microscopical ex- amination and by the re-establishment of the function, the res- torableness of cut nerves ; and he first made use of that faculty in approaching the question of learning whether the sensitive or motor fibers, when stimulated in their middle parts, propagate the irritation toward both the center and periphery at once, or only in one direction. He invented the muscular balance, for measuring the force of the muscle in different states of contrac- tion. He demonstrated that muscular contractility follows the same law as the elasticity of a body which, having the same length as the muscle at its maximum contraction, is stretched out to the length of the muscle at rest. This work on muscular force 2 6o TEE POPULAR SCIENCE MONTHLY. was the beginning of the series of researches by the aid of which Du Bois-Reymond, Helmholtz, and others have built up the general physiology of the nerves and muscles. It was the first instance, says Du Bois-Reymond, of the examination of an emi- nently vital force as if it were a physical one, and of the mathe- matical expression in figures of the laws of its action. Schwann assisted, with the professors at Berlin, in the prepa- ration of the Encyclopedic Dictionary of the Medical Sciences, to which he contributed the articles on vessels, hematose, urinary secretion, and cutaneous secretion. At this period, also, he began the experiments which led up to the discovery of the digestive ferment, pepsin; and the principles which he set forth on the subject are essentially the same as are still taught, the elucidation of a few details being all that has been added. In one of the theses attached to his inaugural dissertation, Schwann had opposed the theory of spontaneous generation, which had begun to prevail again, after a general abandonment of Spa'ilanzani's germ theory. The absence of microbes from prepa- rations which had been hermetically sealed was attributed to the deprivation of oxygen. Schwann and Franz Schulze labored independently to disprove this view. Schulze showed that vege- table and animal infusions could be preserved for months in the presence of air and after renewing supplies of air, if the air was first passed over sulphuric acid to kill the germs in it. Schwann communicated to the Society of German Naturalists and Physi- cians the results of similar experiments, and of others in which he destroyed the germs by calcination. He explained putrefac- tion as a work of decomposition by the germs developing them- selves at the expense of the organic substance, in proof of which he showed that arsenic and corrosive sublimate, which were poi- sonous to infusoria, were also the best preservatives against putre- faction. It remained to be shown that the calcination of the air did not deprive it of its essential properties of sustaining respira- tion and promoting alcoholic fermentation — for the advocates of spontaneous generation might say that the development of life was prevented by asphyxiation. Schwann's view was sustained when he found that frogs suffered no inconvenience in calcined air ; but, when it came to apply the test to the fermentation of alcohol, no fermentation took place. Schwann was not discour- aged by this, but proclaiming a new discovery, that yeast was an organic growth, and working out experiments to prove it, con- verted the apparently hostile result into an additional support to his theory. These ideas did not receive at once the support they deserved. They had a formidable adversary in Liebig, who set forth another theory of fermentation, and ridiculed them with a parody. Schwann, averse to controversy, made no answer to SKETCH OF THE ODOR SCHWANN. 261 Liebig's contradictions or to his joke. He bided bis time. It came in a quarter of a century, when Schwann saw his theory- extended to cover a great variety of chemical and pathological actions, and almost universally accepted ; and received in 1878, from Pasteur, who had carried it to its highest triumph, a letter recognizing him as the one who had opened the road by follow- ing which his own wonderful discoveries were made. These researches might of themselves have sufficed to make the name of Schwann illustrious. But they are relatively but little known because their fame has been dimmed in the face of the incomparable luster of his great discovery of the cell theory. The publication of the book in which the basis of this theory was laid down opened a new era in biological study. We might search in vain, says Simon, in his History of the Natural Sciences, for an example of a more radical revolution in the direction and character of scientific labors than that which was effected in 1838 and 1839 by the publication of Schwann's histogenetic theory. The revolu- tion was sudden, and triumphed, we might say, without resistance. As Henle has remarked, the scientific soil in which this theory took root and grew had been prepared from two different points of view : one, philosophical or ideal ; the other, positive or histo- logical. The philosophical preparation dated from the beginning of the study of Nature, and was illustrated in the propensity of the human mind to look for some simple cause for the diversity of phenomena. To this we owe the monads of Epicurus and Leib- nitz, Oken's philosophy of Nature, and many other efforts ancient and modern. On the other side, certain histological researches, often very modest, but coming close to the facts, had prepared a way for the cell theory. Robert Brown had discovered the cellu- lar nucleus in 1831 ; Mirbel, Von Mohl, and Unger had demon- strated that the organs and tissues of plants were at bottom aggregations of cells in different degrees of transformation. Schleiden had been studying the important part played by the nucleus in the formation of vegetable cells, and had given it the name of cytoblast ; and other authors had found in animals or- gans formed of cells. But these were as yet only isolated facts. Schwann has himself told the story of the way the idea of his discovery first occurred to him. " One day," he says, " when I was dining with M. Schleiden, that illustrious botanist spoke of the important part which the nucleus plays in the development of plant-cells. I at once recollected that I had seen a similar organ in the cells of the dorsal cord, and instantly appreciated the extreme importance the discovery would have if I could show that it plays the same part there as the nucleus of plants in the development of vegetable cells. It must follow, in fact, in conse- quence of the identity of so characteristic phenomena, that the 2 6 2 THE POPULAR SCIENCE MONTHLY. cause which produces the cells of the dorsal cord could not be different from the one that gives origin to the vegetable cells." The two men went together to the amphitheatre of anatomy to examine the nucleuses in question, and Schleiden recognized a complete resemblance between them and the nucleuses of the cells of plants. " From that time," Schwann continues, " all my efforts were directed to finding proof of the pre-existence of the nucleus in the cell." And he goes on to tell how his views were confirmed as his researches advanced. At the time Schwann thus undertook to show that all the organs are of cellular origin, the structure of most of them was very imperfectly known. The application of the microscope to researches in animal histol- ogy was of recent introduction, and everything was to create. Schwann did not shrink from the tremendous task which opened up before him ; and what he had done first for the cartilages and the dorsal cord, he tried in succession for all the other bodily tis- sues ; and in all he had the joy of seeing his idea confirmed. Schwann came upon many new discoveries in the course of these investigations. He first compared the egg to a cell, and rec- ognized cells in the globules of the blastoderm; described the stellar pigmentary cells, the layers of the nail, the development of feathers, the nucleuses of the prisms of the enamel, those of the smooth and striated muscles, the fibers of the dental pulp, the cells destined to be transformed into fibers of the crystalline, etc. He called attention to the envelope of the nervous fibers which bears his name as the sheath of Schwann — all of which discover- ies have been confirmed by modern research armed with its more perfect technic and superior instruments. The theory of the cell as the primordial element of all the tissues was hereafter to serve as the Ariadne's thread to the numerous investigators who devoted themselves to the study of morphology, ' and was to help them explain the infinite variety of organic forms. It gave a definite purpose to the application of the microscope to investigations in anatomy and physiology. It was the foundation of modern physi- ology? and all the morphological progress accomplished during nearly the past half-century has grown out from it. Except for its having familiarized the conception of the constitutional unity of living matter, and having declared the principle that every cell is the product of another cell, the doctrine of selection and descent could not, in the opinion of Edward Van Beneden, have gained ground. Its salutary influence in pathological anatomy and the advance of physiology was immediate and great. Acting in another direction, it put an end to the theory of a special vital force, which was in full sway when it was first promulgated, and raised up that of physico-chemical action, which has taken its place. How was it possible to reconcile the notion of cellular SKETCH OF THE ODOR SCHWANN, 263 individuality with the existence of a single vital force, presiding over the working of all the functions ? It would be necessary to reject such a hypothesis and seek the reason of vital phenomena in the properties of molecules and atoms, or else to assign a vital force in miniature to each cell. Schwann insisted that the hypothesis was both superfluous and insufficient. He could not conceive its existence unless it possessed the attributes of intelli- gent beings ; and preferred to seek the cause of the final purpose in nature in the Creator rather than in the creature. Schwann was just putting in press the book containing his microscopical researches and his later results, when he was in- vited, in his twenty-ninth year, to take the place of Windischman as Professor of Anatomy at Louvain. His position at Berlin was pleasant, but overmodest, and offered no near prospects for pro- motion. So he accepted the proffer, and prepared at the end of 1838 to remove. He had to meet a considerable difficulty, in the beginning of his career at Louvain, from the necessity of speak- ing in French ; but his lectures were successful, and still form the basis of instruction in microscopic anatomy at the university. During his term here he published a memoir on the uses of the bile, the results of which, while it gave a new operation in physio- logical technics, have not been fully confirmed ; applied Quetelet's method of statistics to physiological phenomena; and attempted the artificial production of organic elements. In 1848, Spring, of the University of Lie'ge, finding the com- bined labors of the chairs of Physiology, General Anatomy, and Comparative Anatomy too much for a single professor to perform, asked to be relieved of a part of his burden. Schwann was selected to fill the place, and was installed in November of the same year Professor of Anatomy, Spring reserving to himself the branches of osteology and myology till 1853, when the whole course came under Schwann's charge. Some opposition was expressed at first to the coming of a stranger to the univer- sity ; but this soon passed away, for the brilliant reputation of the new professor, the excellence of his teaching, and the loyalty and amenity of his disposition silenced hostile comment, and won hearts to him. In later years he refused several offers of brilliant scientific positions in Germany — from Breslau in 1852, Wtirzburg and Munich in 1854, and Giessen in 1855. In 1858 he exchanged the chair of Descriptive Anatomy for that of Human Physiology, and in 1870 became an emeritus professor. Clearness, order, and method are described by those who at- tended his lectures as the characteristic qualities of Schwann's teaching. His courses in physiology were eminently demonstra- tive and experimental. Laboratory work always presented a great attraction to him. He was interested in the development of 2 6 4 THE POPULAR SCIENCE MONTHLY. scientific technics, and regularly made himself acquainted with new instruments and methods. He had qualities of heart corre- sponding with the superiority of his mind. His pupils recollect the quiet good-will and fatherly kindness which he showed toward them, and returned them with grateful demonstrations. Although he was actively engaged in scientific pursuits during the whole of his long career, he never mingled in the discussions of the learned world after he went to Belgium. During the five years of his residence in Berlin, his discoveries followed upon one another like the explosions of a piece of fire-works ; and all the great discoveries that made his name illustrious and opened new horizons to scientific thought date from that time. After remov- ing to Belgium, he published only one work, his researches on the uses of the bile. He became almost forgotten outside of Belgium, and many, not hearing his name mentioned any more, thought he was dead. This may be charged to his aversion to personal con- troversy. While the cell theory, as a whole, was established, some of the details gave rise to disputes in which he did not care to en- gage. Believing that he had reached an ultimate principle which time would only establish more strongly, he was willing to let details take care of themselves. But he never lost his interest in the scientific movement ; and, at the time of his death, he was engaged in studying the influence of electrical discharges on the development of the lower beings in organic infusions. In Schwann's theory all the phenomena of life were explained by the properties of atoms. The cell was an aggregation of atoms obeying the laws of nature as if it were a crystal. Plants and animals were aggregations of cells, likewise machines destitute of spontaneity. But man differed from animals by possessing an immaterial element that lifted him above them and gave him freedom. It was in this way that he escaped materialism, and kept himself in line with the Church, to which he submitted his studies, having even sought and obtained ecclesiastical approval for the cell theory before he would publish it. For many years he was collecting materials for a great philosophical work in which the cell theory should take the proportions of a general theory of organisms. Beginning with the definition of the atom, his Theoria, as he called it, was to include all the manifestations of life. Psychological phenomena and the dogmas of the Catho- lic religion were to have definite places in it. Death prevented his beginning the final preparation of it ; and his heirs could only find in his desk a manuscript of seventy-two sheets entitled Man considered from the Physiological Point of View, as he is, and as he is to he.— Translated for the Popular Science Monthly from the Revue Scientifique. CORRESP ONDENCE. 265 CORRESPONDENCE. PRESIDENT HILL'S DEFENSE. Editor Popular Science Monthly : DEAR, SIR : In the April number of your magazine you say that a sen- tence quoted from me by Bishop Vincent in The Chautauquan " is absolutely without foundation." The objectionable sentence is, " Some counselors, like Herbert Spencer, ad- vise us to follow our own self-interest, with- out concern for others, with the assurance that all will thus be happier, because more independent." The quotation is made from my volume of lectures on The Social Influ- ence of Christianity. It is I rather than Bishop Vincent who should " either justify the above statement in regard to Mr. Spen- cer or withdraw it." My respect for Mr. Spencer's ability as a thinker and his sin- cerity as a man is so great that I should certainly withdraw a statement that I felt misrepresented him to those who may not share my high opinion of him. In seeking to render justice to Mr. Spencer, I trust you will not apply the lex talionis to those who may seem to you to do him wrong. The sentence which you condemn as " ab- solutely without foundation " occurs after a criticism of " undiscriminating charity" in the distribution of wealth, and the citation of a case where the literal interpretation of Christ's words, " Give to him that asketh thee," led to the demoralization of a parish. In antithesis to this extreme I name Mr. Spencer as a representative of what I con- sider the opposite extreme — the emphasis of egoism. Of course, I do not mean that Mr. Spencer advocates an absolute and unquali- fied selfishness, taking no account of the rights of others. His teaching is, that there is a u permanent supremacy of egoism over altruism " ; that " each creature shall take the benefits and the evils of his own nature, be they derived from ancestry or those due to self - produced modifications," and that " egoistic claims must take precedence of altruistic claims" (Data of Ethics, pp. 186, 187, 189). He advances two suppositions : (1) "that each citizen pursues his own hap- piness independently, not to the detriment of others, but without active concern for others " ; and (2) " that each, instead of making his own happiness the object of pursuit, makes the happiness of others the object of pursuit"; and argues that the amount of happiness would not be greater in the second case (Data of Ethics, p. 227). He sees " inconsistency " in the doctrine ex- pressed in the Christian maxim — " Love your neighbor as yourself " (Data of Ethics, p. 233). His conclusion is that "general happiness is to be achieved mainly through the adequate pursuit of their own happiness- es by individuals ; while, reciprocally, the happinesses of individuals are to be achieved in part by their pursuit of the general hap- piness " (Data of Ethics, p. 238). Is not the center of concern here for each one his own happiness, with only so much regard for the happiness of others as is likely to reflect hap- piness upon himself ? Mr. Spencer also says : " The poverty of the incapable, the distresses that come upon the imprudent, the starvation of the idle, and those shoulderings aside of the weak by the strong, which leave so many ' in shallows and in miseries,' are the decrees of a large, far-seeing benevolence. It seems hard that an unskillfulness which with all his efforts he can not overcome should entail hunger upon the artisan. It seems hard that a la- borer incapacitated by sickness from com- peting with his stronger fellows should have to bear the resulting privation. It seems hard that widows and orphans should be left to struETEcle for life or death. Neverthe- less, when regarded not separately, but in connection with the interests of universal humanity, these har^h features are seen to be full of the highest beneficence — the same beneficence which brings to early graves the children of diseased parents, and singles out the low-spirited, the intemperate, and the debilitated as the victims of an epidemic " (Social Statics, p. 354). In the foregoing paragraph Mr. Spencer has included types of all the objects of human charity. He himself says (p. 356) : "At first sight these considerations seem conclusive against all relief to the poor — voluntary as well as com- pulsory; and it is no doubt true that they imply a condemnation of whatever private charity enables the recipients to elude the necessities of our social existence." He " makes no objection " to " helping men to help themselves," " countenances it rather," but he shows no concern for those who need our charity because they can not help them- selves. In another book he says, " It may be doubted whether the maudlin philanthropy which, looking only at direct mitigations, persistently ignores indirect mischiefs, does not inflict a greater total of misery than the extremest selfishness inflicts " (The Study of Sociology, p. 345). But all charity inspired by personal sympathy looks mainlv to "di- rect mitigations," and overlooks those " indi- rect mischiefs " which the aid of the inferior is likely to produce. The " extremest self- ishness " would seem from this presentation to be better than interference with that " large, far-seeing benevolence " which Mr. Spencer sees in the operation of the law of consequences. 2 66 THE POPULAR SCIENCE MONTHLY. I am not alone in my view of Mr. Spen- cer'a teaching upon this point. In his criti- cism of The Kan versus the State, in The Popular Science Monthly, vol. xxvii, p. 170, Trof. ile Lareleye says, "The law that Mr. Herbert Spencer desires to adopt is simply Darwin's law — the survival of the fittest." < >n page 1 T'J, after citing a passage explaining the manner in which natural selection among animals is accomplished, M. de Laveleye adds, " This is the ideal order of things which, we are told, ought to prevail in hu- man societies." In his Rejoinder Mr. Spen- cer evades this by saying that his Social Statics was written in 1851, while Darwin's Origin of Species was written in 1859. This le - itisfactory so far as the expression " sur- vival of the fittest" is especially "Darwin's law," but the principle is involved in the operation of the u large, far-seeing benevo- lence" which kills off the weak and helpless, by whatever name it is designated. Mr. Spencer docs not seem to complain of M. de Laveleye's imputation, if the latter means "the survival of the industrially superior, and those who are fittest for the require- ments of social life." I understand Mr. Spencer to oppose carrying the struggles of the "tooth and claw" period into our indus- trial era, but that he is willing to permit the operation of the principle of natural selection with more civilized weapons. In his Rejoinder to M. de Laveleye, Mr. Spencer, after speaking of the distribution of aid by the Government, says, " If others, in their private capacities, are prompted by affection to pity or to mitigate the evil re- sults, by all means let them do so " ; but this assumes the tone of mere sufferance when he immediately adds : " No power can equitably prevent them from making efforts, or giving money, to diminish the sufferings of the unfortunate and the inferior ; at the same time that no power can equitably co- erce them into doing so." I understand this to mean that there is no right in the state to interfere with private charity, if any one is moved to it. In another place Mr/Spencer says (p. 189), "Without wishing to restrain philanthropic action, but quite contrariwise, I have in various places argued that philan- thropy will better achieve its ends by non- governmental means than by governmental means." I understand by this that Mr. Spencer has no wish to " restrain " philan- thropy, and he believes the voluntary form better than the compulsory ; but he does not claim any wish to promote charity, and the kind of "philanthropy" he has in mind seems to be only such as is consistent with his other doctrines. As he views it, true philanthropy is best expressed by non-inter- ference. The greatest happiness is worked out by the law of consequences, which in reality is a " large, far-seeing benevolence." 'Inevitably, then, this law in conformity with which each member of a species takes the consequences of its own nature ; and In virtue of which the progeny of each mem- ber, participating in its nature, also takes such consequences : is one that tends ever to raise the aggregate happiness of the species by furthering the multiplication of the happier and hindering that of the less happy. All this is true of human beings as of other beings" (Data of Ethics, p. 190). I have tried to present the grounds on which my statement regarding Mr. Spencer rests. I think he means to encourage self- reliance as the primary virtue of humanity, and that he seriously believes that what is known in the world as " charity " weakens it. The question is not now whether he is right or wrong, but whether or not this is his teaching. I am aware that my words can be so interpreted as to represent Mr. Spencer as indifferent to human beings other than himself, but that is not my meaning. He distinguishes between acting " to t/ie detriment of others " and acting " without active concern for others' 1 '' (Data of Ethics, p. 227), and I use the words " without concern for others " in his own sense. If you think the word " active " modifies the meaning in any important way, I am willing to introduce it in my sentence, if I can be assured that "concern," which is but passive and not active, has any meaning. Otherwise the ex- pression " active concern " is a pleonasm. Mr. Spencer's doctrine is, as I interpret it, that, if each looks out well for himself, then all will be happy, at least as soon as " adaptation " has been realized ; and until it has, no amount of solicitude for others or sacrifice in their behalf can possibly realize their happiness. Very respectfully yours, David J. Hill. University of Rochester, Rochester, N. Y., April 12, 1890. THE SUSPENSION BRIDGE. Editor Popular Science Monthly : Sir : In reply to the letter of Mr. Gustav Lindenthal (vol. xxxvi, page 844), criticising my remarks as to the lack of stability of sus- pension bridges (page 478), I would like to make the following statement : I do not consider it at all necessary that my remarks upon any of the different types of bridges should be followed by the words "as usually built," as, from thetitle of the article, The Evolution of the Modern Rail- way Bridge, I could not possibly refer to any mode of construction other than that in gen- eral use or some antiquated method. I did refer to the suspension bridge as "usually built," and as such it is very defi- cient in rigidity, and in practice it has been found almost impossible to so brace it later- ally and vertically as to render it in any way a desirable bridge for the passage of our modern heavy trains at a high rate of speed. I refer simply to the suspension bridge up to its present point of evolution, both as EDITOR'S TABLE. 267 to length of span and method of construc- tion, and not to the possible suspension bridge of the future. In regard to the remainder of Mr. Lin- denthal's letter : A bridge to be stable and rigid, in the engineering meaning of the words, must be so designed that under any probable form of loading no change of form can take place, either in the bridge as a whole or any of its parts, other than that due to the elasticity of the material used. The suspension bridge, as we know it, consists of a flexible chain or cable from which the roadway is hung: given a suffi- ciently heavy moving load relative to the dead weight of the bridge, and the form of the curve assumed by this chain or cable will change with each change in the position of the load, and the bridge can not be called stable. The mere fact that the inverted arch is in stable equilibrium while the upright arch is not, has absolutely no bearing upon this question, when we consider the form of the materials that are used in each case. I ad- mit that, if the steel arches of the St. Louis Bridge were inverted and braced and coun- terbraced in a manner similar to that made use of at present, the bridge would be as stable, etc., as the present bridge ; but cer- tainly not- if the vertical and lateral brac- ing were dispensed with, and simply a chain substituted for the present compression arch. It is, however, impossible to state the relative merits of different bridge desi. •les, Robert G., M. D. Evolution of Medical oe. Boston : James H. West. Pp. 16. 10 c<.nt>. Elmer, Dr. G. H.

EYOlution of the Fish-Hook. — "The Evolution of the Fishing-Hook" has been made the subject of a study by Mr. Edward Lovett, who discerns the first implement of the kind in the flint " gorges," and some of the flints, which are called " knives," of the paleolithic "finds." They were fastened, perhaps, to a line of twisted vegetable fiber, or to a thong of one of the whip-like marine algae, by being suspended around the middle. When baited, the " hook " would stand up and down. Swallowed by the fish and jerked up, it would be brought at right angles to the line and stand across the throat of the POPULAR MISCELLANY. 281 fish, so as to bring it along. Another form was a bow, sharpened at both ends and tied around the middle ; or a disk of haliotis- shell, which is still used, in connection with a hook, as a trolling bait for jack or pike. Some very early hooks appear to have been provided with some kind of a barb. Of the bone hooks of the Eskimos, one is mentioned that was carved to resemble a fish ; another had an iron nail for a point ; and another example had the shaft of bone, the point of iron, and a polished stone sinker, showing a combination of the Stone, Bone, and Iron ages in one specimen. The Fijians use a barbless hook of mother-of-pearl for trail- ing over the stern of a canoe, the glitter of which attracts the fish. Some hooks from the Ellis Islands are made of the iron wire in which European packing-cases are bound, which is bent into a curve, the end sharp- ened to a point, and turned inward and downward, and is lashed in such a way that the strain on the hook has a tendency to keep the curve in proper adjustment. One hook is made of a forked limb. In Europe, not many hooks are found anterior to the Iron age. Among the bronze hooks from the lake-dwellings of Switzerland is one very closely resembling the hooks of our own time. An extraordinary specimen is formed of the upper mandible of an eagle, notched down to the base. Hooks in the British Islands have undergone but little change, except in finish and quality, since the dawn of the Iron period. Looking upon the subject as a whole, we find a gradual development from the rudest form of stone, through shell, wood, bone, copper, and iron, down to the beautifully tempered fine steel salmon-hook of the present day ; and we also have exam- ples in which these stages of progression overlap one another, as shown by hooks of compound manufacture, like those of shell and bone, wood and bone, bone and iron, and even stone, bone, and iron together. Cloud-bursts. — Many recent disastrous floods have owed their severity to a sudden down-pour of water occurring when the streams of the surrounding country were already filled by rain which had fallen pre- viously. Such a down-pour is called a cloud- burst. As explained by Prof. Ferrel, in his book on The Winds, great quantities of rain and hail sometimes collect at a considerable height in the vortex of a tornado, being held up by the strong upward current of air.* When the weight of the accumulated mass has become great enough to over- come the force of the ascending current, the rain or hail pours down at one or more points. The whole system may also be- come weak and break up from some other cause, when the same result follows. Thus, if a tornado heavily charged with rain, in moving over the country, strikes a mountain- side, its whirling motion is checked and the upward current weakened, when a cloud- burst results. This is why cloud-bursts oc- cur oftenest on mountain-sides. It is not to be supposed that the accumulation of water would be evenly distributed over all parts of the ascending current, but it would collect at several points ; hence, when it becomes able to force its way down, it descends not in drops, but in streams which often make great holes in the ground. On a steep mountain-side, if the stream continues for a short time only, it may give rise to a land- slide, or may wash out a great ravine, through which the water rushes down to the valley below, carrying rocks and trees along with it. Treatment of Lightning-Shock. — A re- port of a curious case of lightning-shock, with recovery, has been published by Dr. J. B. Paige, of Montreal, with remarks by Drs. Frank Buller and T. Wesley Mills. The sub- ject, a young married woman, was struck by a flash, the intensity of which was shown by its effects on metallic objects to be very great. It passed from a bird-cage, hanging near her, to her head above the left eye, thence along the ear to the central line of the thorax, along the stocking suspender to the top of the stocking, leaving marks on both legs. Thence no trace of the current was detected till the foot was reached, whence it passed, leaving large rents in the stocking and slipper, but no marks on the skin. The force of the shock was enough to throw the woman from the chair on which she was sit- ting, upon and across another some two or three feet distant. She was found complete- ly unconscious, motionless, with muscles re- laxed, left eye closed, right one open, face purple, pulse imperceptible, and neither heart-sounds nor respiratory murmur audi- 282 THE POPULAR SCIENCE MONTHLY. ble. Her clothes were loosened and artificial respiration was begun, and the first sign of life appeared about three minutes afterward. Breathing was greatly impeded, when respira- tion was first resumed, by accumulations of saliva, whieh were removed. Consciousness began to return and the muscles of the arm to regain strength in between half and three quarters of an hour. Sight was restored to the right eye, but it could not be moved. Though the subject could not speak, the pa- ralysis passed away slowly, so that in about two weeks solid food could be swallowed. Twelve or fourteen hours after the accident, intense pain set in about the head, neck, arms, and chest, which did not pass away from the head for seven days, and occurred occasionally after that. At the end of four weeks the patient was able to return to her home. In six months complete recovery had taken place, except in the left eye. To the question whether the patient could have re- covered without the assistance rendered just after the accident, Prof. Mills replies that " considering that respiration was suspended, that the circulation, even with artificial res- piration, was so feeble that the temperature fell, that consciousness did not return for so long, it does not seem reasonable to believe in the possibility of spontaneous recovery. But the case does seem to teach, in the clearest way, the importance of using such means as those employed in this instance promptly and perseveringly." Natural Guides to Land Values.— The chief of the Agricultural College at Down- ton, England, has given in a recently pub- lished article some of the indications by which the fertility of soils may be judged. The following colors indicate barrenness in soils: 1. Black, as being in most cases caused by an excess of vegetable matter or peat. 2. White, as indicating a thin, chalky soil, or the presence of white sand close to the surface. 3. Yellow, whether dark or light. 4. Light gray. 5. Blue. 6. A pie- bald or variegated color. A good soil ought to be from twelve to eighteen inches deep. Alluvial soils owe their fertility in a great measure to their depth. Tenacity docs much to determine the productive power of soil. Tenacity is seen in the clearly cut furrow, and the impression left by the foot when the soil is moist. In tenacious soil the footprint is clear and sharp at the edges, and every nail-mark shows ; whereas, in loamy soil the tread is indistinct and the edges of the footprint crumble away. In dry weather, a cracked surface and hard yellow clods are the marks of a stiff soil. The skillful judge of land will not rely too much upon the physical charac- ter of the soil alone. Land always covers itself with herbage of some sort, from the quality and quantity of which the best pos- sible indication of the soil's yielding power may be obtained. Plenty of timber is a favorable augury. "Who can not recall some beautiful valley where the well-grown trees seem almost to meet their branches over green meadows and patches of grain and other crops ? On the other hand, inclement and thin soils carry a stunted and forlorn timbering. Turning to the sort of tree, we may mention large, spreading oaks as signs of good land. The elm is found to perfec- tion on village greens and near to home- steads where the ground has become, or always was, rich, and in other favored situ- ations. The mulberry and the walnut, the apple and the quince, are never found vig- orous on other than good land ; and the ash, the sycamore, and the chestnut are also in- dications of fertility. Certain other trees indicate the reverse. We see plantations of larch on barren uplands and soils difficult to put to other uses. Scotch fir, spruce, yew, and other cone-bearing trees are often found on poor land. Beeches thrive on the thin- nest of limestone, and the birch will grow in the most unpromising places. Coming down to the plants, none is a more unfailing guide to fertility than chick weed. Nettles never grow on bad land, and dandelions and buttercups are not seen on poor pastures. Thistles also show a good soil. The state of growing crops and the appearance of stubbles should also be noted, although such indications may show rather the character of the farming. Certain wild grasses show barrenness, while grass-land which seems covered with dead, unkempt stuff, like badly made hay, is always barren. Gardening Classes of the Missouri Bo- tanical Garden.— The Trustees of the Mis- souri Botanical Garden, carrying on the in- POPULAR MISCELLANY. 283 tentions of Mr. Shaw, its founder, have prepared a plan of garden scholarships, providing for the instruction of a limited number of pupils in practical horticulture. The classes are intended to consist of six pupils, who will be taught for not more than six years each. They will be regarded as apprentices in the Botanical Garden, and required to work in it under the direction of the head gardener, performing the duties of garden hands, and being advanced gradu- ally from simpler to more responsible tasks. After the first year their working hours will be reduced to five a day, that they may de- vote the rest of the time to study, in which they will enjoy free the privileges of the tuition of the School of Botany at Washing- ton University. For their services in the garden they will be paid from two hundred to three hundred dollars a year, with con- veniently situated lodgings. Applicants for scholarships will be examined in the upper grammar-school branches ; and, in case of an excess of them, will be subjected to com- petitive examination, in which other branches will be brought in. The studies will be, for the first year, in practical duties ; for the second year, vegetable and flower gardening, small- fruit culture, and orchard culture; for the third year, readings in forestry, elementary botany, landscape gardening, and the rudi- ments of surveying and draining; for the fourth year, botany of weeds, garden vege- tables, and fruits ; for the fifth year, vege- table physiology, economic entomology, and fungi ; for the sixth year, botany of garden and greenhouse plants, ferns, and trees in their winter condition, with the theoretical part of some branch of special gardening. Pupils will also be trained in legal forms and in keeping accounts. Two of the six scholarships are at the disposal of local hor- ticultural societies, provided their candidates pass the examinations. Museum of the University of Pennsyl- vania. — The Archaeological Museum of the University of Pennsylvania, begun in Decem- ber, 1889, by the purchase of a small collec- tion of stone implements, has grown in the few months since, till it includes ten thousand objects from all the United States, Mexico, Central America, and parts of South America. It is intended to make it representative of the early civilization of the Americas, and to exhibit as far as possible the implements used by the Indians, in their warfare, agri- culture, and domestic life, before the advent of Columbus. It is intended hereafter to build up the collection mainly by explora- tions, and to this end all parts of the coun- try will be thoroughly searched. In addi- tion to the American specimens, the museum contains a fine collection of flints, bronze implements, and pottery from Europe, and objects from Asia, Africa, and the South Sea islands. Preparations are making by Prof. Rothrock for the establishment in the university of a Museum of Economic Bot- any, to consist of all kinds of woods, vege- table fibers, grains, and drugs, arranged so as to illustrate the processes of manufacture from the raw product, and the various uses to which each material may be put. It is expected to make this department of practi- cal use to manufacturers and wood-workers, who may be guided by its aid to the selec- tion of suitable material, and learn where it can be got. Coffin-IVails. — Baring-Gould has contrib- uted to The Gentleman's Magazine an arti- cle full of curious lore on this sepulchral subject. He says that the studding of a cof- fin with nails — which has evidently not ceased to be common in England — is a curious sur- vival. The nails are no longer of any use, for the lid is fastened down with screws, but even when stone coffins were used — sar- cophagi — the nails were not omitted. Iron was from the first regarded with supersti- tious reverence. In Egypt iron was the symbol of victory over death — of the power of resurrection given to man. The Romans also had a reverence for iron, and attributed to it mysterious powers. By drawing a cir- cle on the ground or in the air, with an iron point, thrice round a person, they believed all noxious influences were banished. An iron spike applied lightly to a wounded part would relieve its pain. Rust for curative and pro- tective purposes might be had from old nails, from which it must be removed with moistened iron. The nail was specially used because it was a symbol of fate. On the Ides of September every year the highest in authority in Rome drove a nail into the wall of the Temple of Jupiter. That day was the 284 THE POPULAR SCIENCE MONTHLY. beginning of the Roman year, and the driv- ing of the nail was thought to bring with it prosperity fur the new year. Livy tells us i , it when the gods seemed hostile and un- moved by the distresses of the nation, the dic- tator broke the spell of evil by driving in a nail. Once a nail driven in had banished a plague ; then a nail had healed discord, riiny says that, if a nail be driven into the pillow on which a man suffering from epilep- sy has laid his head, it will heal him. In all these notices we see iron used as destroying the power of evil, breaking the force of dis- aster, banishing disease, expelling death. Consequently, nails were put in urns or fu- nereal cists to keep away from them every evil power, demons, witches, and as a pledge of final restoration. The iron horseshoe nailed to a door owes its power to break the force of witchcraft not only to its being a symbol of Odin's horse, but also to the met- al of which it is composed. Shears were fre- quently buried with bodies down till late in the middle aires. It is said that even within O the memory of man they have been buried in coffins with corpses in Swabia. Some- times as many as five were laid in the coffin with one corpse. The idea was the same as with nails — the metal was the important mat- ter, rather than the form it took. The steel or iron was a preservative to the corpse, a protection and an assurance of resurrection. For the same reason that nails and shears were buried with the dead, swords were laid with them, and not necessarily because they would need them in the next world. Even Charlemagne was buried with his sword. The Icelandic sagas are full of stories of cairns broken into by heroes to rob the dead of their swords. Already in historic times the significance of the sword buried with the dead was lost ; and in the Saga of Olaf the Saint a ghost actually invites a Norseman to break into his tomb and relieve him of his sword and other valuables. Habits of the Manatee. — The London Zoological Society has acquired a living spe- cimen of the manatee, one of the only two kinds of " herbivorous cetaceans " now ex- isting. Concerning the habits of these ani- mals, Miss Agnes Crane has written, from observations of a pair several years ago in the Brighton Aquarium, that lettuce and endives, of which they could eat thirty pounds a day, formed their favorite food. The male would devour at a pinch leaves of the cabbage, turnip, and carrot. Both rel- ished those of the dandelion and sow-thistle. Sometimes the animals would swim about and pursue the leaves floating on the water ; at other times the plants were seized in their mouths, drawn down, and eaten under the water, while the hand-like fore-fins were em- ployed in separating the leaves. The food was invariably swallowed below the surface. They are not at all at ease when out of the water, but seem oppressed by their bulk. The male was observed to make a few at- tempts at terrestrial progress by turning himself round and moving a few inches when the tank was empty. With jaws and tail- fin pressed closely to the ground, the body of the animal became arched, and was moved by a violent lateral effort, aided and slightly supported by the fore paddles, which were stretched out in a line with the mouth. But the effect of these very labored efforts was not commensurate with their violence ; and their relation to active locomotion might be compared to the state of a man lying prone, with fettered feet and elbows tied to his side. Odd Dishes of the Olden Time. — The cook-books of a hundred or more years ago afford reading well adapted to excite curi- osity of appetite, if we may speak in that way. Their lists of pickles and flavors em- braced a great many articles that we do not think now of using in that way. Jams were made of vegetables ; parsnips, raspber- ries, etc., were made into cakes ; and beets, potatoes, and oranges into biscuits. For making violet cakes the directions were to " take the finest violets you can get, pick off the leaves, beat the violets fine in a mortar with the juice of a lemon, beat and sift twice their weight of double-refined sugar, put your sugar and violets into a silver saucepan or tankard, set it over a slow fire, keep stirring it gently until all your sugar is dissolved ; if you let it boil it will discolor your violets ; drop them in china plates ; when you take them off put them in a box, with paper between every layer." Wines were made of every fruit ; of such flowers and vegetables as cowslips and parsnips ; POPULAR MISCELLANY. 285 from flowers and berries of elder ; from syc- amore, walnut, blackberry, and balm. To make shrub, to one gallon of milk flavored with lemons and Seville oranges were added two quarts of red wine, two gallons of rum, and one gallon of brandy. The books give directions how to spin gold and silver webs for dessert, to spin birds' nests, to make a Chinese temple or obelisk, a fish-pond with silver and gold fishes, a hen's nest with strips of lemon for straw, and eggs filled with flummery, and a hen and chickens in jelly. To make a "desert island," "take a lump of paste and form it into a rock three inches broad at the top, set in the middle of a deep china dish, and set a cast figure on it with a crown on its head and a knot of sugar-candy at its feet, etc. ... If this dish is for a wedding supper, put two figures in- stead of one." There are also recipes for a " rocky island," a " floating island," with sheep and swans, " or you may put in snakes or any wild animals of the same sort," " Sol- omon's temple in flummery," " moonshine," and " moon and stars in jelly " — a half-moon with seven stars shining out of flummery colored with cochineal and chocolate to imi- tate the color of the sky. Among solid dishes the books tell how to make porcupine of a breast of veal, to surprise a shoulder of mutton or any other joint, to dress a joint to look like a hen and chickens, to bombard veal, to transmogrify pigeons, to Florent'ne a hare, make a Solomon Gundy, make an artificial turtle, and barbecue a pig. Trees and Malaria. — According to Prof. Corrado Tommassi Crudelli, some of the prevalent notions respecting relations of for- ests and malaria are mistaken ones. The relations are not direct. Forests do not contribute to the propagation of malaria un- less they are growing upon a malarious soil ; and they can not make a soil malarious which would not be malarious without them. But they favor the development of malaria, when it is already there, by intercepting the solar rays, and thus checking evaporation and retaining moisture in summer. When the obstacle to the direct action of the solar rays is removed from infected land, the sum- mer drying lessens the malarious generation, and in some favorable circumstances may even arrest it. The idea prevails in Rome that forests act as a screen to prevent mala- ria from crossing them by causing it to be filtered out in their foliage, and the estab- lishment of forests at certain places is ad- vised for that purpose. But it has been proved that the destruction of woods and forests in such situations has not led to an increase of malaria, but frequently to its mitigation by promoting better drainage and improved cultivation. The production of fe- vers in the Agro Romano and in Rome is the result of a complexity of meteorological and physiological conditions. An abundant development of malaria is verified only when the malarious soil is damp and warm. The malarious charge of the atmosphere may vary greatly according to the different pro- portion of the two indispensable factors of malaria — heat and moisture. If both are at their maximum, so is the malaria, especially when the sky is clear. When the malarious charge of the atmosphere has been great for many days in succession, and the bodies of the inhabitants have become more or less impregnated with the malarious germs, a fall of temperature may be very injurious, by causing an arrest of the germs within the organism and preventing their rapid elimination by the secretions. Hence it is that northern winds exercise an unfavorable influence during the fever seasons. Soda Salts in Arizona. — The deposits of sulphate of soda of the valley of the Verde River, Arizona, have long been known and extensively quarried by the rancheros of the region to obtain a substitute for salt for cat- tle and horses. They have recently been visited by William P. Blake, who found the deposits of thenardite and allied minerals associated with it to cover several acres in extent, and reach a thickness of fifty or sixty feet or more. They appear as a series of rounded hills, with sides covered with a snow-white efflorescence and a greenish-col- ored and yellow clay at the bottom and top, partially covering the saline beds. The bulk of the deposits consists of thenardite, in a coarsely crystalline mass, so compact and firm that it has to be got out by drilling and blasting. The white efflorescence on the hills is composed of the hydrous sulphate of soda {mirabilite), which occurs in close as- sociation with the thenardite. Other asso- 286 THE POPULAR SCIENCE MONTHLY. ciatdl minerals are rock-salt in beautifully transparent masses, sparingly disseminated ; the anhydrous sulphate of lime and soda (glauh, rib | ; and " pseudomorphs," in which- the glauberite having disappeared, its place is supplied by amorphous carbonate of lime exactly filling the matrices of its crystals. Iloly Things and Toys from Torres Strait. — Prof. A. C. Haddon has fitted up in the British Museum a collection of objects from Torres Strait, which illustrates the customs and superstitions of the people of that still savage quarter. Among the ob- jects are some forty native skulls, some of which had been strung in bunches as trophy decorations of the hut of a warrior, while others had been used for ceremonies and divination. The great eccentric masks em- ployed in semi-religious and secular dances are represented by specimens which the col- lector believes to be the last of their kind. One of them, a crocodile mask, had such striking powers that the native from whom it was obtained refused to put it on for fear that death would be the consequence, be- cause it was not the season of the year when it might be legitimately worn. Of the charms, those in stone and wood shaped like dugongs are very interesting. There are charms to protect against poisoning, love- charms, rain-making charms, charms to make the tobacco-plant grow ; female figures, some in coral to keep the fire in when the house- wife is absent ; and taboo figures and signs of various kinds. The musical instruments include some ingenious drums, "bull-roar- ers," and a new kind of simple construction. Of toys there are tops of considerable weight, of which the Papuan spins several on his toes at the same time, and arrangements of string used as a sort of cat's cradle. The implements and articles of clothing and those for personal adornment are varied. An or- nament worn by a betrothed girl appears to be derived from two fish-hooks placed back to back. Several specimens grimly illustrate the old savage customs. A hard- wood weapon is marked with eleven notches, to indicate as many heads which the owner has cut off. A double cassowary head-dress that belonged to a late king of the island Tud was handed over by his son to Prof. Haddon, together with the boar-tusks which he wore in his mouth on war expeditions, on the understanding that they were to go to the British Museum, where "plenty men" wanted to see them. When drawings or photographs of some of the natives were be- ing taken they would ask, " Queen Victoria, he see picture along we fellow ? " — that is, Will Queen Victoria see our picture ? — to which the professor replied in the same strain, " S'pose he want> he see ; I no savee. Plenty men along England want to savee about you fellow." Some of these photo- graphs may now be seen in this collection, recording features and decorations which, in a few years, will have died out. NOTES. Dr. S. Weir Mitchell, of Philadelphia, recently received from a woman-patient the singular present of a cord of white-oak wood, chopped down and sawed up by her own hands. He had recommended to her an act- ive, outdoor life in the woods for nervous invalidism. She had followed his directions, with results of which the cord of sawed wood was one of the evidences. Dr. E. N. Sneath, lecturer on the His- tory of Philosophy at Yale, has been inspir- ing the preparation of a series of small vol- umes of selections from the leading philoso- phers from Descartes down, so arranged as to present an outline of their systems. Each volume will contain a biographical sketch of the author, a statement of the historical po- sition of the system, and a bibliography. Those so far arranged for are Descartes, by Prof. Ladd, of Yale ; Spinoza, by Prof. Fuller- ton, of the University of Pennsylvania ; Locke, by Prof. Russell, of Williams ; Berke- ley, by ex-President Porter, of Yale ; Hume, by Dr. Sneath, of Yale ; and Hegel, by Prof. Royce, of Harvard. Kant, Comte, and Spen- cer will certainly be added to the series, and others if encouragement is received. The publishers will be Henry Holt & Co. The American Academy of Political and Social Science, of which Prof. Edmund J. James is president, was founded in December, 1 889, for promoting the study of the polit- ical and social sciences, particularly of those which are omitted from the programmes of other societies, or which do not at present receive the attention they deserve. Among them are sociology, comparative constitu- tional and administrative law, philosophy of the state, and portions of the field of politics. It will attend to the publication of material that will be of use to students which does not now reach the public in any systematic way. The plan of the academy includes meetings for the presentation of papers and NOTES. 287 communications, the establishment of a li- brary, and the dissemination of knowledge through publications and by other means. The Messrs. Merriam, publishers of Web- ster's Dictionary, issue a circular calling at- tention to the misleading way in which a cheap reprint of an old edition of Webster's Unabridged Dictionary is being advertised. It is the edition of 1847, the copyright of which has expired by the lapse of forty-two Tears. It lacks all the words that have been added to the language since 184*7, and these, especially in the department of science, have been many ; it contains numerous etymolo- gies that have been proved erroneous by the results of later research ; it lacks the tables of biographical, geographical, and other in- formation, which are appended to recent edi- tions of Webster, and it has no illustrations in the body of the volume. The reprint is produced by some method of photogravure, giving blurred letters, very trying to the eyes, and the paper and binding are so flimsy that the book must fall to pieces with very little use. It is not the current edition of Web- ster's Unabridged Dictionary, as its publish- ers wish the public to believe — it is not even the "original" edition, as it explicitly claims to be, for that was published in 1828. The most interesting feature of Dr. R- W. Shufeldt's report to the American Or- nithologists' Union on Progress in Avian Anatomy for the Years 1888-1889, is the announcement that a Handbook to the Muscles of Birds has been prepared by the author, and is in the press of Macmillan & Co. It is based on studies of the raven. Several monographs, mostly technical, by Dr. Shu- feldt and other authors, American and for- eign, are mentioned in the report. Among them is one by Mr. F. A. Lucas, on the Skele- ton of the Extinct Great Auk. A clear and forcible article on The Sup- pression of Consumption, by G. W. Hamble- ton, is published in Science for April 25th. Dr. Hambleton deems the most important step in suppressing this disease to be to re- duce its production. The means which he recommends for this end are almost entirely hygienic, and are based on the theory that consumption is produced by conditions that impede the respiratory functions. The chief of these are compression of the chest, and the presence of dust in the air inhaled. His statements are well fortified by cases which he has treated successfully, including his own. The first fossil found in the " Cheyenne sandstone " of Kansas — which is considered referable to the Trinity division of Arkansas and Texas — is described by Mr. F. W. Cragin as a part of a cycad, similar to those from the Purbeck Dirt-beds of England, but dif- fering from them in form and in the size of the petioles. A leaf of Platanus, found in a stratum of very fine, soft chalk of supposed Niobrara Cretaceous age, is described by the same author as of interest, both on account of its preservation in a kind of rock in which land vegetation is rare, and because it con- tributes evidence that chalk is sometimes formed very near land, and if so, then pre- sumably in water of but moderate depth. The increase of leprosy in British Guiana is attracting attention. It was introduced by negroes from Africa, and added to by immigrants from India in 1842 and 1858, and from China in 1861 and 1862. One Indian tribe was infected with it fifty years ago from the negro colony, but no other tribe has had it. Mr. J. D. Hilles, of Deme- rara, who has investigated the subject, is convinced that the disease is communicable by marriage or cohabitation, and by inocula- tion or contact. He has seen cases that un- doubtedly arose by contagion. The investigations of Dr. Th. Kocher, of Berne, on goitre, while they do not clear up the question of the origin of the disease, cast a dim light upon it. Comparing the water of the parts of his canton in which goitre is common with those parts that are free from it, the author found considerable quan- tities of organic or organized material in it. In certain goitrous parts, particular families having access to special water-supplies free, or relatively so, from this organic material are free from goitre, although breathing the same air, living on the same soil, engaging in the same occupations, and eating the same food with their goitrous neighbors. Hence, he concludes, the organic factor is the one that determines the prevalence of goitre. Mr. Joseph Thomson commends the semi- civilized region forming the central area of the Niger basin as one of the most promis- ing fields for commerce in all tropical Africa. It is densely populated, and is divided into powerful and, for Africa, well-governed em- pires, in which life and property are fairly secure. The people have made some ad- vance in civilization, and are famed for the excellence of their manufactures. Inland trade is organized, an efficient transport service exists, labor is abundant, the Niger presents an uninterrupted water-way to the very heart of the region, and the country is healthy, for Africa. A large stump of Syringodendron alter- nans, discovered some time ago standing in the coal mines of St. Etienne, France, is about ten feet high, three feet in diameter at the starting-point of the roots, and twenty inches in diameter at the top. The roots re- semble the fossil Siigmaria. The trunk has the cicatrices and flutings of the Sigillaria, and the leaves seem to have been linear. In a prostrate tree (upper part) of the same species a few feet from this one, the leaf- scars were more clearly marked, but smaller. 288 THE POPULAR SCIENCE MONTHLY. Dr. E. Pagf.t Thurston believes that while it is theoretically right to omit farina- ceous food in feeding infants that have to be brought up by hand, a little is needed when cow's milk is used, to retard curdling. These' solids, as well as the preparations of barley, Isinglass, and linseed, act mechanically by adding something to thicken the milk, and entangle the curds as they are formed. In the shape of bread-crust, Brighton biscuit, or other " infant's foods," they may be added in very small quantities, so that the milk can still be sucked through the tube of a feed- ing-bottle. Cases of lead-poisoning among the Jac- quard weavers in a Swiss factory were traced by F. Schiiler to the dust from leaden weights which are used by the weavers to carry the thread of their warp. After the varnish has been rubbed off from the weights, the lead begins to wear away, and falls in fine parti- cles among the dust on the floor. In some, cases this dust is as much as 56*86 per cent lead, and even when the utmost care was taken, nine or ten per cent of lead was found in it. According to Mr. Ilansen-Blansted, the beech is overcoming all other trees in the struggle for existence in the Danish forests. It is driving out the birch, except in marshy places ; it is taking the place of the firs ; and there are signs that it is gradually gaining the advantage over the oaks. OBITUARY NOTES. Sir Robert Kane, a distinguished Irish chemist and author, died in Dublin, Febru- ary 16th. He was born in Dublin in Sep- tember, 1810. His father was the proprietor of sulphuric-acid and alkali works near the city, and he developed a taste for chemical knowledge very early in life, publishing his first paper— On the' Existence of Chlorine in the Native Peroxide of Manganese— in 1828. This was followed by other contribu- tions. He was appointed Professor of Nat- ural Philosophy to the Dublin Society in 1834, and devoted himself to original re- search in chemistry. He was afterward head of the Museum of Irish Industry, and first President of Queen's College, Cork. He was author of a large and important work on the Industrial Resources of Ireland. He received many honors, in reco£mition of his scientific labors, from the Government and from learned societies. M. Edmond Hebert, an eminent French geologist, died April 4th, in the seventy- eighth year of his age. He was made Pro- fessor of Geology at the Sorbonne in 1857, and in the same year was chosen to succeed Charles Sainte-Claire Deville in the Section of Mineralogy in the Academy of Sciences. He was author of many important geological memoirs. His principal works were on the Oscillations of the Crust of the Earth, and the Ancient Seas and their Shores in the Paris Basin. He was an exponent of the doctrine of the adequacy of existing causes to explain geological phenomena. Prof, von Quenstedt, of Tubingen, one of the most famous of German paleontolo- gists, and a mineralogist, too, died December 21st. He was author of works on the Jura, and one on petrifactions or fossils. He was distinguished for his profound knowl- edge of the Lias of Wiirtemberg and its fossils. Dr. Paul Niemeyer, Sanitarv Counselor, and author of works relating to hygiene, died in Berlin, on the 25th of February, in the fifty-sixth year of his age. Several of his books, including his Doctrine of Health, Advice to Mothers, and Sunday Rest, had wide circulation, and were translated into other languages. He assisted Miss Nightin- gale in the revision of her Notes on Nursing. M. Charles M. V. Montigny, a Belgian astronomer and meteorologist, died near Brussels, March 16th, aged about seventy years. He was honorary professor in the Royal Athenaeum of Brussels, and a member of the Belgian Academy of Science ; and had been connected with the observatory as a correspondent since 1879. His most im- portant researches were on the scintillation of the stars, for which he invented an instru- ment called the scintillometer, which he ob- served industriously for several years, and which led him to new views concerning re- fraction ; the relation of the height of the barometrical column and the pressure of the wind ; the velocity of the wind, and its in- clination. In the last research he is believed to have been the first who occupied himself with the subject. Dr. George Thurber, an eminent bota- nist and writer on horticultural subjects, died in Passaic, N. J., April 2d, in the sev- entieth year of his age. He was born in Providence, R. I., in 1821. Studying phar- macy, he became interested in botany. In 1850, in connection with the United States and Mexico Boundary Survey, he explored the botany of the country between the Gulf of Mexico and the Pacific Ocean. The re- sults of this, study were published by Asa Gray in Plantae Novas Thurberianae. He was from 1859 to 1863 Professor of Botany and Horticulture in the Agricultural College of Michigan. As editor of the American Agri- culturist, from 1863 till 1885, he made it the ablest and most influential journal of its class. He published, in 1859, American Weeds and Useful Plants — an enlargement of Darlington's Agricultural Botany; con- tributed on botanical subjects to Appletons' Cyclopaedia ; and made a thorough, systematic study of grasses. MATTHEW FONTAINE MAURY. THE POPULAR SCIENCE MONTHLY. JULY, 1890. NEW CHAPTERS IN THE WARFARE OF SCIENCE. IX. THE ANTIQUITY OF MAN AND PEEHISTORIC ARCHAEOLOGY. By ANDREW DICKSON WHITE, LL. D., L. H. D., EX-PRESIDENT OF CORNELL UNIVERSITY. WHILE the view of chronology based npon the literal accept- ance of Scripture texts was thus shaken by researches in Egypt, another line of observation and thought was slowly devel- oped, even more fatal to the theological view. From a very early period there had been dug from the earth, in various parts of the world, strangely shaped masses of stone, some rudely chipped, some polished ; in ancient times these were generally considered as thunderbolts, and known as " thunder- stones." This idea was carried into the middle ages, and we find in the eleventh century an emperor of the East sending to the Emperor Henry IV, of Germany, a " heaven axe " ; and, in the twelfth century, a Bishop of Rennes asserting the value of thun- der-stones as a divinely appointed means of securing success in battle, safety on the sea, security against thunder, and immunity from unpleasant dreams : even as late as the seventeenth century a French ambassador brought a stone hatchet, which still exists in the museum at Nancy, as a present to the Prince-Bishop of Ver- dun, and claimed for it health-giving virtues. Yet, as early as the latter part of the sixteenth century, Michael Mercati tried to prove that the " thunder-stones " were weapons or implements of early races of men, though from some cause his book was not published until the following century, when other thinking men had begun to take up the same idea. But early in the eighteenth century a fact of great importance was quietly established : in the year 1715 a large pointed weapon of black flint was found in contact with the bones of an elephant, vol. xxxvii. — 22 zgo THE POPULAR SCIENCE MONTHLY. in a gravel-bed near Gray's Inn Lane, in London. The world in general paid no heed to this ; if the attention of theologians was called to it, they dismissed it summarily with a reference to the Deluge of Noah ; but the specimen was labeled, the circumstances regarding it were recorded, and both specimen and record care- fully preserved. In 1723 Jussieu addressed the French Academy on The Origin and Uses of Thunder-stones. He showed that recent travelers from various parts of the world had brought a nunibei* of weapons and other implements of stone to France, and that they were es- sentially similar to what in Europe had been known as " thunder- stones " : a year later this fact was clinched into the scientific mind of France by the Jesuit Lafitau, who published a work showing the similarity between the customs of aborigines then existing in other lands and those of the early inhabitants of Europe. So began, in these works of Jussieu and Lafitau, the science of comparative ethnography. In 1730 Mahudel presented a paper to the French Academy of Inscriptions on the so-called " thunder-stones," and also presented a series of plates which showed that these were stone implements, which must have been used at an early period in human history. In 1778 Buffon, in his Epoques de la Nature, intimated his belief that " thunder- stones" were made by early races of men; but he did not press this view, and the reason for his reserve was obvious enough : he had already one quarrel with the theologians on his hands, which had cost him dear — public retraction and humiliation ; his declaration, therefore, attracted little notice. In the year 1800 another fact came into the minds of thinking men in England. In that year John Frere presented to the Lon- don Society of Antiquaries sundry flint implements found in the clay-beds near Hoxne ; that they were of human make was certain, and, in view of the undisturbed depths in which they were found, the theory was suggested that the men who made them must have lived at a very ancient geological epoch ; yet even this discovery and theory passed like a troublesome dream, and soon seemed to be forgotten. About twenty years later Dr. Buckland published a discussion of the subject, in the light of various discoveries in the drift and in caves. It received wide attention, but theology was hushed to silence by his soothing concession that these striking relics of human handiwork, associated with the remains of various extinct animals, were proofs of the Deluge of Noah. In 1823 Boue*, of the Vienna Academy of Sciences, showed to Cuvier sundry human bones found deep in the alluvial deposits of the upper Rhine, and suggested that they were of an early geo- logical period; this Cuvier virtually, if not explicitly, denied: NEW CHAPTERS IN THE WARFARE OF SCIENCE. 291 great as he was in his own field, he was not a great geologist ; he, in fact, led geology astray for many years. Moreover, he lived in a time of reaction ; it was the period of the restored Bonrbons — of the Yoltairean King Lonis XVIII, governing to please orthodoxy. Bond's discovery was, therefore, at first opposed, then enveloped in studied silence. Cnvier evidently thought, as Voltaire had felt under similar circumstances, that " among wolves one must howl a little " ; and his leading disciple, Elie de Beaumont, who succeeded him in the sway over geological science in France, was even more opposed to the new view than his great master had been. Bou^s discoveries were, accordingly, apparently laid to rest forever.* In 1825 Kent's Cavern, near Torquay, was explored by the Rev. Mr. McEnery, a Roman Catholic clergyman, who seems to have been completely overawed by orthodox opinion in England and elsewhere; for, though he found human bones and imple- ments mingled with remains of extinct animals, he kept his notes in manuscript, and they were only brought to light more than thirty years later by Mr. Vivian. The coming of Charles X, the last of the French Bourbons, to the throne, made the orthodox pressure even greater. It was the culmination of the reactionary period — the time in France when a clerical committee, sitting at the Tuileries, took such measures as were necessary to hold in check all science that was not per- fectly " safe " ; the time in Austria when Kaiser Franz made his famous declaration to sundry professors, that what he wanted of them was simply to train obedient subjects, and that those who did not make this their purpose would be dismissed ; the time in Germany when Nicholas of Russia and the princelings and min- isters under his control, from the King of Prussia downward, put forth all their might in behalf of " scriptural science " ; the time in Italy when a scientific investigator, arriving at any conclusion distrusted by the Church, was sure of losing his place and in dan- ger of losing his liberty ; the time in England when what little science was taught was held in due submission to Archdeacon Paley's doctrines and the Thirty-nine Articles ; the time in the United States when the first thing essential in science was, that it be adjusted to the ideas of revival preachers. Yet men devoted to scientific truth labored on ; and in 1828 * For the general history of early views regarding stone implements, see the first chap- ters in Cartailhac, La France Prehistorique ; also Joly, L'Homme avant les Metaux ; also Lyell, Lubbock, and Evans.

Tournal, of Narbonne, discovered in the cavern of Bize specimens of human industry, with a fragment of a human skeleton, among bones of extinct animals. In the following year Christol pub- lished accounts of his excavations in the caverns of Gard ; he had found in position, and under conditions which forbade the idea of after-disturbance, human remains mixed with bones of the extinct hyena of the early Quaternary period. Little general notice was taken of this, for the reactionary orthodox atmosphere involved such discoveries in darkness. But in the French Revolution of 1830 the old politico-theologi- cal system collapsed : Charles X and his advisers fled for their lives ; the other continental monarchs got glimpses of new light ; the priesthood in charge of education were put on their good be- havior for a time, and a better era began. Under the constitutional monarchy of the house of Orleans in France and Belgium less attention was therefore paid by Govern- ment to the saving of souls ; and we have in rapid succession new discoveries of remains of human industry, and even of human skeletons so mingled with bones of extinct animals as to give ad- ditional proofs that the origin of man was at a period vastly ear- lier than any which theologians had dreamed of. A few years later the reactionary clerical influence against science in this field rallied again. Schmerling in 1833 explored a multitude of caverns in Belgium, especially at Engis and Engi- houl, and found human skulls and bones closely associated with bones of extinct animals, such as the cave bear, hyena, elephant, and rhinoceros, while mingled with these were evidences of hu- man workmanship in the shape of chipped flint implements ; dis- coveries of a similar sort were made by De Serres in France and Lund in Brazil ; but, at least as far as continental Europe was concerned, these discoveries were received with much coolness, both by Catholic leaders of opinion in France and Belgium, and by Protestant leaders in England and Holland. Schmerling him- self appears to have been overawed, and gave forth a sort of apol- ogetic theory, half scientific, half theologic, vainly hoping to sat- isfy the clerical side. Nor was it much better in England. Sir Charles Lyell, so devoted a servant of prehistoric research thirty years later, was still holding out against it on the scientific side ; and, as to the theological side, it was the period when that great churchman, Dean Cockburn, was insulting geologists from the pulpit of York Minster, and the Rev. Mellor Brown denouncing geology as " a black art," " a forbidden province " ; and when in America Prof. Moses Stuart and others like him were belittling the work of Benjamin Silliman and Edward Hitchcock. In 1840 Godwin Austin presented to the Royal Geological So- NEW CHAPTERS IN THE WARFARE OF SCIENCE. 293 ciety an account of his discoveries in Kent's Cavern near Torquay, and especially of human bones and implements mingled with, bones of the elephant, rhinoceros, cave bear, hyena, and other extinct animals ; yet this memoir, like that of McEnery fifteen years before, found an atmosphere so unfavorable that it was not published. But just at the middle of the nineteenth century came the be- ginning of a new epoch in science — an epoch when all these earlier discoveries were to be interpreted by means of investigations in a different field : for, in 1847, a man previously unknown to the world at large, Boucher de Perthes, published at Paris the first volume of his work on Celtic and Antediluvian Antiquities, and in this he showed engravings of typical flint implements and weap- ons, of which he had discovered thousands upon thousands in the high drift beds near Abbeville in northern France. The significance of this discovery was great indeed — far greater than Boucher himself at first supposed. The very title of his book showed that he at first regarded these implements and weap- ons as having belonged to men overwhelmed at the Deluge of Noah ; but it was soon seen that they were something very differ- ent from proofs of the literal exactness of Genesis : for they were found in terraces at great heights above the river Somme, and, under any possible theory having regard to the truth, must have been deposited there at a time when the river system of northern France was vastly different from anything known in the historic period. The whole discovery indicated a series of great geologi- cal changes since the time when these implements were made, re- quiring cycles of time compared to which the space allowed by the orthodox chronologists were as nothing. His work was the result of over ten years of research and thought. Year after year a force of men under his direction had dug into these high-terraced gravel deposits of the river Somme, and in his book he now gave, in the first full form, the results of his labor. So far as France was concerned, he was met at first by what he calls " a conspiracy of silence," and by a contemptuous opposition among orthodox scientists, at the head of whom stood Elie de Beaumont. This heavy, sluggish opposition seemed immovable : nothing that Boucher could do or say appeared to lighten the pressure of the orthodox theological opinion behind it — not even his belief that these fossils were remains of men drowned at the Deluge of Noah, and that they were proofs of the literal exactness of Gene- sis seemed to help the matter. His opponents felt instinctively that such discoveries boded danger to the accepted view, and they were right : Boucher himself soon saw the folly of trying to account for them by the orthodox theory which he had adopted at first. 294 THE POPULAR SCIENCE MONTHLY. And it must be confessed that not a little force was added to the opposition by certain characteristics of Boucher de Perthes himself ; gifted, f oresighted, and vigorous as he was, he was his own worst enemy ; carried away by his own discoveries, he jumped to the most astounding conclusions : the engravings in the later volume of his great work, showing what he thought to be human i hires and inscriptions upon some of the flint implements, are worthy of a comic almanac ; and at the great National Museum of Archseology at St. Germain, beneath the shelves bearing the remains which he discovered, which mark the triumph of a great new movement in human science, are drawers containing speci- mens hardly worthy of a penny museum, from which he drew the most unwarranted inferences as to the language, religion, and usages of prehistoric man. But Boucher triumphed none the less. Among his bitter oppo- nents at first was Dr. Rigollot, who in 1855, searching earnestly for materials to refute the innovator, dug into the deposits of St. Acheul — and was converted : for he found implements similar to those of Abbeville, making still more certain the existence of man dur- ing the Drift period. So, too, Gaudry a year later made similar discoveries. But most important was the evidence of the truth which now came from other parts of France and from many other countries. The French leaders in geological science had been held back, not only by awe of Cuvier, but by recollections of Scheuchzer. Ridi- cule has always been a serious weapon in France, and the ridicule which finally overtook the adherents of the attempt of Scheuchzer, Mazurier, and others, to square geology with Genesis, was still re- membered. From the great body of French scientists, therefore, Boucher secured at first no aid. His support came from the other side of the Channel. The most eminent English geologists, such as Falconer, Prestwich, and Lyell, visited the beds at Abbeville and St. Acheul, convinced themselves that the discoveries of Boucher, Rigollot, and their colleagues were real, and then quietly but firmly told England the truth. And now there appeared a most effective ally in France. The arguments used against Boucher de Perthes and some of the other early investigators of bone caves had been that the implements found might have been washed about and turned over by great floods, and therefore that they might be of a recent period ; but in 1861 Edward Lartet published an account of his own excava- tions at the Grotto of Aurignac, and the proof that man had ex- isted in the time of the Quaternary animals was complete. This grotto had been carefully sealed in prehistoric times by a stone at its entrance ; no interference from disturbing currents of water had been possible ; and Lartet found, in place, bones of eight out NEW CHAPTERS IN THE WARFARE OF SCIENCE. 295 of nine of the main species of animals which, characterize the Quaternary period in Europe ; upon them were marks of cutting implements, and in the midst of them coals and ashes. Close upon these came the excavations at Eyzies by Lartet and his English colleague, Christy. In both these men there was a sobriety and a carefulness in making researches and in stating results which converted many of those who had been repelled by the enthusiasm of Boucher de Perthes. The two colleagues found buried together, in the stony deposits made by the water dropping from the roof of the cave at Eyzies, the bones of numerous ani- mals extinct or departed to arctic regions, one of. these a vertebra of a reindeer with a flint lance-head still fast in it, and with these were found evidences of fire. Discoveries like these were thoroughly convincing. But there still remained here and there a few gainsayers in the supposed in- terest of Scripture, and these, in spite of the convincing array of facts, insisted that in some way, by some combination of circum- stances, these bones of extinct animals of vastly remote periods might have been brought into connection with all- these human bones and implements of human make in all these different places, without supposing that these ancient relics of men and animals were of the same period. But a new class of discoveries came to silence this contention. At La Madeleine in France, and at vari- ous other places, were found rude but striking carvings and en- gravings on bone and stone representing sundry specimens of those long-vanished species. These specimens, or casts of them, can now be seen in all the principal museums. They show the hairy mammoth, the cave bear, and various other animals of the Quaternary period, carved rudely but vigorously by contemporary men ; and, to complete the significance of these discoveries, travel- ers returning from the icy regions of North America have brought similar carvings of animals now existing in those regions, made by the Eskimos during their long arctic winters to-day.* * For the explorations in Belgium, see Dupont, Le Temps Prehistorique en Belgique.

As a result of these discoveries and others like them, showing that man was not only a contemporary with long-extinct animals of past geological epochs, but that he had already developed into a stage of culture above pure savagery, the tide of thought began to turn. Especially was this seen in 1863, when Lyell published the first edition of his Geological Evidence of the Antiquity of Man; and the fact that he had so long opposed the new ideas re 'force to the clear and conclusive argument which led him to renounce his early scientific beliefs. Research among the evidences of man's existence in the early Quaternary, and possibly in the Tertiary period, was now pressed forward along the whole line. In 1864 Gabriel Mortillet founded his review devoted to this subject; and in I860 the first of a series of scientific congresses devoted to such researches was held in Italy. These investigations went on vigorously in all parts of France and spread rapidly to other countries. The explorations which Dupont began in 1861, in the caves of Belgium, gave to the museum at Brussels eighty thousand flint implements, forty thousand bones of animals of the Quaternary period, with a num- ber of human skulls and bones found mingled with these remains. From Germany, Italy, Spain, America, India, and Egypt similar results were reported. Especially noteworthy were the further explorations of the caves and drift throughout the British Islands. The discovery by Colonel Wood in 1861, of flint tools in the same strata with bones of the earlier forms of the rhinoceros, was but typical of many. A thorough examination of the caverns of Brixham and Torquay, by Pengelly and others, made it still more evident that man had existed in the early Quaternary period : the existence of a period before the Glacial epoch or between different glacial epochs in England, when the Englishman was a savage, using rude stone tools, was then fully ascertained, and, what was more significant, there were clearly shown a gradation and evolution even in the history of that period. It was found that this ancient Stone epoch showed progress and development : in the upper lay- ers of the caves, with remains of the reindeer, who, although he has migrated from these regions, still exists in more northern cli- mates, were found stone implements revealing some little advance in civilization ; next below these, sealed up in the stalagmite, came, as a rule, another layer, in which the remains of reindeer were rare and those of the mammoth more frequent, the im- plements found in this stratum being less skillfully made than produced to-day by the Eskimos and others, see Lubbock, Prehistoric Times, chapters x and xiv. For very striking exhibitions of this same artistic gift in a higher field to-day by descendants of the barbarian tribes of northern America, see the very remarkable illustrations in Rink, Danish Greenland, London, 1877, especially those in chap. xiv. NEW CHAPTERS IN THE WARFARE OF SCIENCE. 297 those in the upper and more recent layers ; and, finally, in the lowest levels, near the floors of these ancient caverns, with re- mains of the cave bear and others of the most ancient extinct ani- mals, were fonnd stone implements evidently of a yet ruder and earlier stage of human progress. No fairly unprejudiced man can visit the cave and museum at Torquay without being con- vinced that there were a gradation and evolution in these begin- nings of human civilization. The evidence is complete ; the masses of breccia taken from the cave, with the various soils, im- plements, and bones carefully kept in place, put this progress beyond a doubt. All this indicated a great antiquity for the human race ; but in it lay the germs of still another great truth, even more important and more serious in its consequences to the older theologic view, and this will be discussed in the following chapter. But new evidences came in, showing a yet greater antiquity of man. Remains of animals were found in connection with human remains, which showed not only that man was living in times more remote than the earlier of the new investigators had dared dream, but that some of these early periods of his existence must have been of immense length, embracing climatic changes be- tokening different geological periods: for with remains of fire and human implements and human bones were found not only bones of the hairy mammoth and cave bear, woolly rhinoceros and reindeer, which could only have been deposited there in a time of arctic cold, but bones of the hyena, hippopotamus, saber-toothed tiger, and the like, which could only have been deposited when there was in these regions a torrid climate. The conjunction of these remains clearly showed that man had lived in England early enough and long enough to pass through times when there was arctic cold and times when there was torrid heat ; times when great glaciers stretched far down into England and indeed into the continent, and times when England had a land connection with the European continent, and the European continent with Africa, allowing tropical animals to migrate freely from Africa to the middle regions of England. The question of the origin of man at a period vastly earlier than the sacred chronologists permitted was thus absolutely settled ; but among the questions regarding the existence of man at a period yet more remote, the Drift period, there was one which for a time seemed to give the champions of science some difficulty. The orthodox leaders in the time of Boucher de Perthes, and for a considerable time afterward, had a weapon of which they made good use ; the statement that no human bones had yet been discovered in the drift. The supporters of science 29 8 THE POPULAR SCIENCE MONTHLY. naturally answered that few if any other bones as small as those of man had been found, and that this fact was an additional proof of the great length of the period since man had lived with the extinct animals; for, since specimens of human workman- ship proved man's existence as fully as remains of his bones could do, the absence or even rarity of human and other small bones simply indicated the long periods of time required for dissolving them away. Yet Boucher, inspired by the genius he had already shown, and filled with the spirit of prophecy, declared that human bones would yet be found in the midst of the flint implements, and in 18G3 he claimed that this prophecy had been fulfilled by the dis- covery at Moulin Quignon of a portion of a human jaw deep in the early Quaternary deposits. But his triumph was short-lived ; the opposition ridiculed his discovery ; they showed that he had offered a premium to his workmen for the discovery of human remains, and they naturally drew the inference that some tricky laborer had deceived him. The result of this was, that the men of science felt obliged to acknowledge that the Moulin Quignon discovery was not proved. But ere long human bones were found in the deposits of the early Quaternary period, or indeed of an earlier period, in various other parts of the world, and the question regarding the Moulin Quignon relic was of little importance. We have seen that researches regarding the existence of pre- historic man in England and on the Continent were at first mainly made in the caverns ; but the existence of man in the ear- liest Quaternary period was confirmed on both sides the English Channel, in a way even more striking, by the close examination of the drift and early gravel deposits. The results arrived at by Boucher de Perthes were amply confirmed in England. Rude stone implements were found in terraces a hundred feet and more above the levels at which various rivers of Great Britain now flow, and under circumstances which show that, at the time when they were deposited, the rivers of Great Britain in many cases were entirely different from those of the present period, and formed parts of the river system of the European continent. Re- searches in the high terraces above the Thames, the Ouse, as well as at other points in Great Britain, placed beyond a doubt the fact that man existed on the British Islands at a time when they were connected by solid land with the Continent, and made it clear that, within the period of the existence of man in northern Eu- rope, a large portion of the British Islands had been sunk to depths between fifteen hundred and twenty-five hundred feet beneath the Northern Ocean — had risen again from the water — had formed part of the continent of Europe, and had been in NEW CHAPTERS IN THE WARFARE OF SCIENCE. 299 unbroken connection with Africa, so that elephants, bears, tigers, lions, the rhinoceros and hippopotamus, of species now mainly extinct, had left their bones in the same deposits with human implements as far north as Yorkshire. Moreover, connected with this fact came in the new conviction, forced upon geologists by the more careful examination of the earth and its changes, that such elevations and depressions of Great Britain and other parts of the world were not the results of sudden cataclysms, but of slow processes extending through vast cycles of years — processes such as are now known to be going on in various parts of the world. Thus it was that the six or seven thousand years allowed by even the most liberal theologians of former times were seen more and more clearly to be but as a mere nothing in the long succession of ages since the appearance of man. Confirmation of these results came from various other parts of the world, especially from the drift deposits both on the east- ern and western coasts of America. The discoveries at Trenton, New Jersey, and at various places in Delaware, Ohio, Minnesota, and elsewhere, along the southern edge of the drift of the glacial epochs, clinched the new scientific truth yet more firmly ; and the statement made by an eminent American authority is, that " man was on this continent when the climate and ice of Greenland extended to the mouth of New York Harbor." The discoveries of prehistoric remains on the Pacific coast, and especially in British Columbia, finished completely the last chance at a reasonable contention by the adherents of the older view. As to these inves- tigations on the Pacific slope of the United States, the discoveries of Whitney and others in California had been so made and an- nounced that the judgment of scientific men regarding them was suspended until the visit of perhaps the greatest living authority in his department, Alfred Russel Wallace, in 1887. He confirmed the view of Prof. Whitney and others with the statement that " both the actual remains and works of man found deep under the lava-fiows of Pliocene age show that he existed in the New World at least as early as in the Old." To this may be added the discoveries in British Columbia, which prove that, since man ex- isted in these regions, * valleys have been filled up by drift from the waste of mountains to a depth in some cases of fifteen hun- dred feet ; this covered by a succession of tuffs, ashes, and lava- streams from volcanoes long since extinct, and finally cut down by the present rivers through beds of solid basalt, and through this accumulation of lavas and gravels." The immense antiquity of the human remains in the gravels of the Pacific coast is summed up by a most eminent English authority and declared to be proved, "first, by the present river systems being of subse- quent date, sometimes cutting through them and their superin- 3 oo THE POPULAR SCIENCE MONTHLY. cumbent lava-cap to a depth, of two thousand feet ; secondly, by the great denudation that lias taken place since they were depos- ited, for they sometimes lie on the summits of mountains six thousand feet high ; thirdly, by the fact that the Sierra Nevada has been partly elevated since their formation." * As an important supplement to these discoveries of ancient implements came sundry comparisons made by eminent physiolo- * For the general subject of investigations in British prehistoric remains, see especially Boyd Dawkins, Early Man in Britain and his Place in the Tertiary Period, London, 1880.

Human bones had been found under these circumstances as early as 1835 at Canstadt near Stuttgart, and in 1856 in the Nean- derthal near Dusseldorf ; but in more recent searches they have been discovered in a multitude of places, especially in Germany, France, Belgium, England, the Caucasus, Africa, and North and South America. But comparison of these bones showed that even in that remote Quaternary period there were great differences of race, and here again came in an argument for the yet earlier ex- istence of man on the earth ; for long previous periods must have been required to develop such racial differences. Considerations of this kind have given a new impulse to the belief that man's ex- istence dates back at least into the Tertiary period. The evidence for this earlier origin of man has been ably summed up not only by its brilliant advocate, Mortillet, but by a former opponent, one of the most conservative of modern anthropologists, Quatref ages ; and the conclusion arrived at by both is, that man did really ex- ist in the Tertiary period. The acceptance of this conclusion is also seen in the recent work of that most able investigator, Alfred Russel Wallace, who, cautious and conservative as he is, places the origin of man not only in the Tertiary period, but in an earlier stage of it than most have dared assign; even in the Miocene. The first thing raising a strong presumption, if not giving proof, that man existed in the Tertiary, was the fact that from all explored parts of the world came in more and more evidence that in the earlier Quaternary man existed in different, strongly marked races and in great numbers. From all regions which geologists had explored, even from those the most distant and dif- ferent from each other, came this same evidence — from northern Europe to southern Africa ; from France to China ; from New Jersey to British Columbia ; from British Columbia to Peru. The development of man in such numbers and in so many different regions, with such differences of race and at so early a period, must have required a long previous time. This argument seemed to be strengthened by discoveries of bones bearing marks apparently made by cutting instruments, in the Tertiary formations of France and Italy, and by the dis- coveries of what were claimed to be flint implements by the Abbe' Bourgeois in France, and of implements and human bones by Prof. Capellini in Italy. On the other hand, some of the more cautious men of science are content to say that the existence of man in the Tertiary period is not yet settled. As to his existence throughout the Quaternary epoch no new proofs are needed. Even so determined a supporter 02 THE POPULAR SCIENCE MONTHLY. of the theological side as the Duke of Argyll has been forced to yield to the evidence. Of attempts to make an exact chronological statement throw- in «• light on the length of the various prehistoric periods, the most notable have been those by M. Morlot, on the accumulated strata of the Lake of Geneva ; by Gillieron, on the silt of Lake Neuf chatel ; by Horner, in the delta deposits of Egypt ; and by Riddle, in the delta of the Mississippi. But while these have failed to give anything like an exact result, all these investiga- tions together point to the one great truth so amply established, of the vast antiquity of man, and the utter inadequacy of the orthodox chronology based by theologians upon our sacred books. The period of man's past life upon our planet, which has been fixed by the universal Church, " always, everywhere, and by all," is thus perfectly proved to be merely trivial compared with those vast geological epochs during which man is now known to have existed.* -♦♦♦- GREENLAND AND THE GREENL ANDERS. \ By ELISEE EECLUS. TILL recently Hooker, Payer, and others supposed that the interior of Greenland presented vast spaces free of ice, grassy valleys where herds of reindeer grazed, and popular legends were appealed to in support of this view. Nordenskjold also sug- gested that the phenomenon might be explained by the action of the winds, which after crossing the inland ranges descended in warm currents like the fohn of Switzerland, and thus melted the snows of the valleys. But the systematic researches made in re- cent years have failed to discover any of these inland oases. The whole land appears, on the contrary, to be covered with a continu- ous ice-cap fringed by glaciers which move down the outer valleys to the neighborhood of the sea, or to the fiords of the periphery. The valleys themselves have disappeared, and, despite local irregu- * As to the evidence of man in the Tertiary period, see works already cited, especially Quatrefages, Cartailhac, and Mortillet.

Thus, in certain places the explorer should expect to meet elevations of seven thousand or eight thousand feet ; but, owing to an optical illusion, he scarcely knows whether he is climbing or descending. The horizon seems to rise on all sides, says Nordensk- jold, " as if he were at the bottom of a basin." The aspect of these boundless wastes rolling away in scarcely perceptible undulations, and in the distance mingling the gray of their snows with the gray of the skies, at first gave the impression that Greenland was a uniform plateau, a sort of horizontal table. The belief now prevails that the rocky surface of the land is, on the contrary, carved into mountains and hills, valleys and gorges, but that the plastic snows and ice have gradually filled up all the cavities, which now show only in slight sinuosities on the surface. Allowing to the whole mass of the ice-cap an average thickness of five hundred feet, it would represent a total volume of about one hundred and fifty thousand cubic miles. This sermer sudk, or " great ice " of the Greenlanders, flows like asphalt or tar with extreme slowness seaward, while the surface is gradually leveled by the snow falling during the course of ages and distributed by the winds. In the interior of the country the surface of the ice and snow is as smooth as if it were polished, looking like " the undisturbed surface of a frozen ocean, the long but not high bil- lows of which rolling from east to west are not easily distinguish- able to the eye." * Nevertheless, the exterior form of the ice-cap has been greatly diversified, at least on its outer edge, where in many places it is difficult to cross, or even quite impassable. The action of lateral pressure, of heat produced by the tremendous friction, of evaporation and filtration, has often broken the surface into innumerable cones a few yards high, in form and color resem- bling the tents of an encampment. The depressions of the snowy plateau are filled with meres, lagoons, and lakes ; streams and riv- ulets excavate winding gorges with crystal walls in the snow and ice. Cascades, frozen at night, plunge during the day into pro- found crevasses ; during the expedition of 1870 Nordenskjold saw intermittent jets of water rising to a great height, which he was unable to study, but which he supposes must be geysers. Most of the glaciers reaching the coast round the Greenland seaboard present a somewhat regular frontal line, from which blocks of varying size break off with every wave and drift away with the current. But the frozen streams which yield those huge masses large enough to be called icebergs, that is, " mountains of ice," are relatively few in number, their production requiring a combination of favorable circumstances, such as the thickness of * Nansen, Proceedings of the Royal Geographical Society, August, 1889. 304 THE POPULAR SCIENCE MONTHLY. the parent glacier, the form of its bed, and the depth of the water at its mouth. The larger fragments originate for the most part along that remarkable break which is presented in the normal for- mation of the coast-line between Egedesminde and the Svartenhuk Peninsula. Rink enumerates not more than thirty Greenland gla- ciers which discharge really large icebergs, and of this number only six or eight yield blocks of the first magnitude. The average velocity of the congealed masses is about fifty feet in the twenty-four hours, but in some places a much greater speed has been recorded, though still varying considerably with the seasons. A branch of the Augpadlartok glacier, north of Upernavik, moves at the rate of one hundred feet a day, the high- est yet measured. But how enormous must be the pressure of the inland ice-fields to discharge into the sea the vast quantities of ice- bergs which are yearly sent adrift along the Greenland seaboard ! Estimated in a single block the annual discharge from each of the five best-known glaciers would represent a mass of about seven- teen billion cubic feet in capacity, and fifty-six hundred feet in height, depth, and thickness. Reduced to a liquid state this mass would be equivalent to a stream discharging seaward five hun- dred cubic feet per second, or 15,500,000 a year. The formation of this drift ice, or floating icebergs, is one of those phenomena which were discussed long before the seaboard had been studied, or before the breaking away of the frozen masses had actually been witnessed. "Wherever the glaciers discharge through a broad valley preserving a uniform width and depth for a considerable space, and advancing seaward through a fiord of like dimensions, and with gently sloping bed, the ice may pro- gress without any of those accidents caused by the inequalities of more rugged channels. Under such conditions the compact mass glides smoothly forward over its rocky bed without developing any rents or fissures. But as it moves down like a ship on its keel, it tends to rise, being at least one twentieth lighter than the displaced water. It is also left without support by the sudden fall of its bed beyond the normal coast-line. Nevertheless, it still continues its onward movement through the waters to a point where its weight prevails over its force of cohesion with the frozen stream thrusting it forward. At this point it snaps off suddenly with a tremendous crash, and the iceberg, enveloped in»a thousand fragments projected into space, plunges into the abyss and whirls round and round to find its center of gravity amid the troubled waters. On recovering from the bewilderment caused by all this tumult and chaos, the spectator finds that the glacier has apparently receded a long way toward the head of the bay, in the middle of which a crystal peak is seen slowly drifting away with the current. . In this he recognizes the huge fragment detached GREENLAND AND THE GREENLANDERS. 305 H - w hi < w QQ H — S H O O -J a a Z C a — M vol. xxxvii. — 23 3° 6 THE POPULAR SCIENCE MONTHLY. < rr. Eh (■'.

If Greenland, like other regions, passed through a glacial epoch, the fossil remains preserved in its sedimentary rocks show that it had also its hot and temperate periods.

The upper chalk beds, abounding in vegetable forms, analogous to those of the subtropical and temperate zones, had already been examined by Giesecke at the beginning of this century. They supplied to Nordenskjold a very remarkable flora, especially rich in dicotyledonous plants represented by numerous families of Cycadea, a tree-fern, and even a bread-fruit tree. At that time the mean temperature must have been as high as 68° Fahr. The Miocene flora, whose general physiognomy corresponds to a more temperate climate, averaging about 53° or 54° Fahr., is il- lustrated by splendid specimens discovered chiefly in Disco Island 3 o8 THE POPULAR SCIENCE MONTHLY. and the surrounding peninsulas. Quite a fossil forest is buried under the ferruginous mass of Mount Atanekerdluk, a peak which rises to a height of over a thousand feet over against Disco, and which is now surrounded by glaciers on all sides. From these de- posits Whymper, Nordenskjold, and others have extracted one hun- dred and sixty-nine species of plants, of which about three fourths were shrubs and trees, some with stems as thick as a man's body. Altogether there have been discovered in the Greenland strata as many as six hundred and thirteen species of fossil plants. The most prevalent tree is a Sequoia, closely resembling the Oregon and Calif ornian giants of the present epoch. Associated with this conifer were beeches, oaks, evergreen oaks, elms, hazel-nuts, wal- nuts, magnolias, and laurels ; and these forest trees were festooned with the vine, ivy, and other creepers. A leaf of a Cycadea found among these fossil remains is the largest ever seen ; and a true palm, the Flabellaria, has been discovered among the remains of these old arctic forests. To develop such a flora the climate of north Greenland must at that time have been analogous to that at present enjoyed on the shores of Lake Geneva, twenty-four degrees nearer to the equator. According to the same gradation of temperature, the dry lands about the north pole itself must at the same epoch have had their forests of aspens and conifers. According to Oswald Heer, the change that has taken place in the climate since then represents a fall of 30° or 40° Fahr. for north Greenland. The interval between these two ages was marked by the Glacial period, whose traces are visible on the west coast. Although incomparably poorer than that of Miocene times, the present flora of Greenland is sufficient to clothe extensive tracts with a mantle of mosses, grasses, and brushwood. Wherever the snows melt under the influence of the sun or of the warm east winds, herbaceous and other lowly plants spring up even on the exposed nunatdkher, and to a height of five thousand feet. Owing to the uniform intensity of the solar heat, the summer flora is almost identical on the low-lying coast-lands and highest mount- ain-tops. True trees occur in the southern districts, where Egede was said to have measured some nearly twenty feet high. But the largest met by Rink during all his long rambles was a white birch fourteen feet high growing amid the rocks near a Norse ruin. Few trees, in fact, exceed five or six feet, while most of the shrubs become trailing plants. Such are the service and alder, which on the coast reach 65° north latitude ; the juniper, which ad- vances to 67° ; and the dwarf birch, which ranges beyond 72°. In its general features the Greenland flora, comprising about four hundred flowering plants and several hundred species of lichens, greatly resembles that of Scandinavia. Hooker and Dr. GREENLAND AND THE GREENLANDERS. 309 Robert Brown regard it as essentially the same as that of the north European highlands and lacustrine regions. Even on the west coast, facing America, this- European physiognomy is said to prevail, although to a less degree than on the opposite side, which appears to be much poorer in vegetable forms. But, though lim- ited, the American element is important, supplying to the natives numerous edible berries, alga?, and fuci, which have saved whole tribes from starvation during periods of scarcity. The Europeans have also their little garden-plots, where they grow lettuce, cab- bage, turnips, and occasionally potatoes about the size of school- boys' marbles. The great bulk of the present population consists of Danes, Danish half-breeds, and the Eskimo proper, more or less modified by crossings with the early Norse settlers. Nearly all the inhabit- ants, already Christianized and civilized by the missionaries, are grouped in parishes, whose organization differs from correspond- ing European communities only in those conditions that are im- posed by the climate and the struggle for existence. There still survive, however, a few tribes of pure Eskimo stock, such as those recently discovered by European explorers beyond the Danish ter- ritory north of Melville Bay and on the east coast. Others also may perhaps exist along the shores of unvisited or inaccessible fiords. But the most northern camping-ground hitherto discovered is that of Ita (Etah), situated in Port Foulke on Smith Sound, in 78° 18' north latitude. In 1875 and again in 1881 it was found aban- doned ; but it is known to have been previously inhabited, and the natives had returned to the place in 1882 and 1883.* When vis- ited by Hall and his party, this little group of twenty persons, who had never seen any other human beings, fancied that the strangers were ghosts, the souls of their forefathers descending from the moon or rising from the depths of the abyss. In their eyes the ships of John Ross were great birds, with huge, flapping wings. Among the Greenland Eskimo are most frequently found men of average and even high stature, especially on the east coast. Most of those on the west side are short, but thick-set and robust, with short legs, small hands, and a yellowish- white complexion. The face is broad and flat, the nose very small, the eyes brown and slightly oblique like the Chinese ; the hair black, lank, and falling over the forehead ; the expression mild, suggesting that of the seal, the animal which is ever in their thoughts, and whose death is their life. They have also the seal's gait and carriage, as well as a rounded figure well lined with fat to protect it from the cold. What essentially distinguishes the Eskimo from the Mongolian, with whom he was till recently affiliated, is the extremely " doli- * Greely, Three Years of Arctic Service. 3io THE POPULAR SCIENCE MONTHLY. chocephalous " form of his head, the skull, with its vertical sides and sharp crest, often affecting a " scaphocephalous " or boat-like shape. According to Dall, the cranial capacity is higher than that of the red-skins. Both sexes are dressed very much alike. European fashions, however, have already penetrated among the Greenlanders, and in many districts men are now met wearing the garb of European laborers, while the women deck themselves with cotton stuffs and many-colored ribbons. But in winter no costume could advan- tageously replace their capacious boots, sealskin pantaloons, close- fitting jacket, and the amaut, or hood which "keeps baby warm/' In Danish Greenland the women no longer tattoo their chin, cheeks, hands, or feet, nor do they now insert variegated threads under the skin, the missionaries having interdicted these " pagan " practices. Singing, dancing, the relation of the old legends, even athletic games among the young people, were also formerly sternly repressed. Indul- gence in strong drinks is allowed only once a year, on the anniversa- ry of the King of Denmark, and the royal monopoly of the trade with Greenland is justi- fied on the ground that in this way the importation of spirits is pre- vented. Posses sing- great natural in- telligence com- bined with love of instruction, the Greenlanders may justly claim to be civilized. The great majority read and write their mother - tongue, and sing European melodies, while several speak English or Danish. Nearly all the families have their little library, and read their Eskimo newspaper, as well as the collections of national legends, illustrated with engravings by native artists.

Formerly, the right of property was restricted to objects of personal use, such as clothes and weapons ; the hunting-grounds belonged to the whole community, and the produce of the chase or fisheries was equally distributed among all. The rights of communal property were also regulated and safeguarded by gen- eral assemblies followed by public banquets. But the Europeans have changed all that by introducing the principle of sale and purchase, by enlarging to their own profit the rights of personal ownership, and proclaiming the new gospel of "every man for himself." The result is a general impoverishment and moral degradation of the people. They are no longer like the Eskimo visited by Graah on the east coast — " the gentlest, the most upright and virtuous of men." Nevertheless, the language possesses not a single abusive term, and it is impossible to swear in Eskimo. The part of Greenland where Eric the Red built his strong- hold, and where the banished Norsemen flocked around him, is still one of the least deserted regions, as it also is the most fertile and temperate. Julianahaab, capital of this district, contains one fourth of the entire population of the country grouped on the banks of a small stream in a grassy valley near a deep fiord, which is unfortunately not easily accessible to shipping. Upernivik (Upernavik) and Tasiusak, lying still farther north in 73° 24' north latitude, are the last European settlements in Greenland, gloomy abodes lost amid the snows at the foot of yel- lowish or brick-red rocks. In winter the sun sets for eighty days, yet by a sort of mockery this glacial district bears an Eskimo name meaning " spring." The horrors of war were extended to this extremity of the habitable world at the beginning of the present century, when Upernavik was burned by the English whalers, and all communication between Greenland and Den- mark interrupted for the seven years from 1807 to 1814. The Siamese Government is taking great pains to encourage the speedy develop- ment of the enormous potential resources of the country, and has sagaciously done much in that direction. Telegraphs have been established ; schools, hospitals, and other public buildings have been erected, and are increasing every day. A tramway company, supported mainly by Siamese capital, is running street cars in the me- tropolis. A river flotilla company, wholly Siamese, carries the passenger traffic of the stream on which Bangkok is built ; important gold-mining operations have been begun by a company, in which a majority of the subscribers are Siamese ; and a trunk line of railway is under contract. A large and lucrative export trade in cattle has sprung up ; and mills, docks, and fleets of German and Eng- lish ships, all doing a flourishing business, attest the prevalence of a spirit of enterprise. EVOLUTION AND DISTRIBUTION OF ANIMALS. 313 EVOLUTION AND THE DISTRIBUTION OF ANIMALS.* By DAVID STARR. JORDAN, PRESIDENT OF THE UNIVERSITY OF INDIANA. I. ""VTO one with good eyes and brains behind them has ever -i-N looked forth on the varied life of the world — on forest or field or brook or sea — without at least once asking himself this question : " What is the cause of nature's endless variety ? " We see many kinds of beasts and birds and trees and flowers and in- sects and blades of grass, yet when we look closely we find not one grass-blade in the meadow quite like another blade. Not one worm is like its fellow-worm, and not one organism in body or soul is the measure of its neighbor.' You may search all day to match one clover-leaf, and, should you succeed, even then you have failed ; for, if the two leaves agree in all physical respects, they may still be unlike in that which we can not see, their ancestries, their potentialities. Again, with each change of conditions, of temperature, of moisture, of space, of time, with each shifting of environment, the ranga in variety increases. " Dauer in Wechsel " (persistence in change) ; " this phrase of Goethe," says Amiel, "is a summing up of nature." And the naturalist will tell you that the real variety is far greater than that which appears. He will tell you that, where commonness seems to prevail, it is the cover of variety. The green cloak which covers the brown earth is the shelter under which millions of organisms, brown or green, carry on their life-work. Each recognizable kind of animal or plant is known in biology as a species. The number of forms now considered as distinct species is far beyond the usual conception of those who have not made a special study of such matters. I have an old book in my library, the tenth edition of the Systema Naturse, published by Linngeus in 1758. This book treats of all the species of animals known a little more than a century ago. In its eight hundred and twenty-three pages some four thousand different kinds of animals are named and briefly described. But for every one of these enumerated by Linnaeus, more than one hundred kinds are known to the modern naturalist, and the number of species still unknown doubtless exceeds the number of those already recorded. Every year for the last quarter of a century there has been pub- lished in London a plump octavo volume known as the Zoological Record. Each of these volumes, larger than the whole Systema * An address delivered before the Chicago Institute, in a course on the Testimony of Science in regard to Evolution. vol. xxxvii. — 24- 3 i4 THE POPULAR SCIENCE MONTHLY. Naturae, contains the names of the species new to science added to our lists during the year of which it treats ; and in the record of each year we find the names of two or three times as many as are mentioned in the whole Systema Naturae. Yet the field shows no signs of exhaustion. As these volumes stand on the shelf together, it is easy to see that the later volumes are the thickest, and that the record for the present year is the largest of all. The additional species named and described in 1889 are more than ten thousand. Moreover, what is true of the increase of knowledge in systematic zoology, is even more marked in the case of botany. Such, then, is the variety of life on the globe — a variety of which Linnaeus and his successors had never dared to dream. And yet, great as this variety is, there are, after all, only a few types of structure among all animals and plants — some three or four or eight or ten general modes of development — all the rest being minor variations from these few types. It is even true that all life is but a series of modifications of a single plan ; for all organisms are composed of cells, the essential element of which is always a single substance — protoplasm. All are governed by the same laws of development, reproduction, and susceptibility to outside influences. Unity in life is therefore not less a fact than is life's great diversity. In whatever way we account for the diversity, the essential unity must not be forgot- ten. The bonds of unity among organisms constitute what the naturalist calls homology. That these resemblances have some deep significance, no thoughtful student of nature has ever doubted. What this sig- nificance may be is the underlying question in that branch of philosophy which has come to be known as evolution. In the present discussion I shall take for- granted that answer to these questions which is associated with the name of Darwin ; and, as a student of the relations and distribution of animals, I firmly believe that no answer to these questions fundamentally different from his will ever be possible. The essence of the Darwinian theory is this, that the various species of the present day are all derived from pre-existing forms, more or less unlike them ; that this derivation takes place through the operation of natural laws — the law of heredity, the law of response to external stimulus or environment, and the law less clearly understood by which variations from ancestral types are constantly produced; the "divine initiative" in the individual which struggles against sameness and monotony. The constant tendency of organisms to multiplication by geometric progression in a world of limited extent, already apparently full, brings about a constant struggle for existence among these organisms, and by this struggle, we have the progressive adjustment of individuals -EVOLUTION AND DISTRIBUTION OF ANIMALS. 315 to tlieir environment — an adjustment which is made more and more complete by the ceaseless destruction of the unadjusted. According to this theory, the * same causes which have produced difference of species in the past must be still at work, and must continue to produce similar differences in the future. To the theory of derivation is opposed the old idea of " special creation." But this theory of special creation has never had in science other than a provisional existence. It was a mere name for a process not understood. If each of the millions of species of animals and plants living and extinct came about by a " special creation," then special creation can not be an operation outside the limits of law. It is simply the name given in ignorance to the law by which species are produced. What has been done so many times must be done in some uniform way. What this way is, the theory of evolution professes in some degree to define. The fact is, the theory of development gives the only clew by which the naturalist can be guided in his work. If the mutual affinities of species do not depend on the law of heredity, they are unintelligible. They are impossible. If the variation of species is really immutability in disguise, we can not trust our senses. We are left to choose between some form of the development theory and a hopeless unscientific agnosticism, content with the surface facts, and ignorant of the laws of which these facts are the expression. I do not wish to-night to discuss either the general question of evolution nor that special theory of the method of evolution which is associated with the name of the master of modern zool- ogy. I shall take evolution and Darwinism for granted, and con- fine myself to a statement of certain facts and principles in the science of zoogeography and to their bearing on the question of the origin of species. There are many difficulties in bringing the facts of this science down to the needs of concrete illustration. A science so broad as to include all human history at once with the history of every group of animated organisms can not well be compressed into a discussion of a single hour. And with this I may recall the additional difficulty, present in all discussions of the subject of evolution, of distinguishing single illustrations from arguments. Isolated cases of geographical variations in species would not have great value as arguments for the develop- ment theory were the cases really isolated. The force lies in this fact, that these cases are typical ; that what may be said of one is true of a thousand. In like manner the full force of the laws of homology and he- redity can only be felt when their effect is cumulative, as in the mind of the anatomist who has followed each organ through its protean disguises in a wide range of forms. 316 THE POPULAR SCIENCE MONTHLY. Still, again, the force of the argument drawn from embryology does not come from a knowledge of the changes in a single egg. All these studies need the second premise, obtained by years of comparison in different fields of investigation, that no case is iso- lated. Without this premise, the argument would be incomplete. The few cases of development or change which can be brought to popular notice are simply illustrations and not proofs. As Prof. Bergen has well said, "it is important that we should understand that none of the kinds of evidence in favor of evolution loses so much by being represented only by scattered instances as the argument from distribution." And, conversely, no argument is so strong when all the known facts are brought into consideration together. The universal fact of the mutability of species can be really understood or appreciated only by him by whose eyes multitudes of species have been seen to change. To the ordinary observer the species seems constant, just as the face of a cliff seems constant. To the student of nature mutability is everywhere. Just as the wind and rain and frost quietly but surely change the face of a cliff, so do other forces of nature as quietly but as surely change the face of a species. And now we may notice that it was precisely this phase of the subject, the relation of species to geography, which first attracted the attention of both Mr. Darwin and Mr. Wallace. Both these observers noticed that island life is neither strictly like nor unlike the life of the nearest land, and that the degree of difference varies with the degree of isolation. Both were led from this fact to the theory of derivation, and to lay the greatest stress on the progressive modification resulting from the struggle for existence. In the voyage of the Beagle, you remember, Mr. Darwin was brought in contact with the singular fauna of the Galapagos Isl- ands, that cluster of volcanic rocks which lies in the open sea some six hundred miles west of the coast of Equador and Peru. The sea birds of these islands are essentially the same as those of the coast of Peru. So with most of the fishes. We can see how this might well be, for both sea birds and fishes can readily pass from the one region to the other. But the land birds, as well as the reptiles, insects, and plants, are mostly peculiar to the islands. The same species are found nowhere else. But other species very much like them in all respects are found, and these all live along the coast of Peru. In the Galapagos Islands, according to Dar- win's notes, " there are twenty-six land birds ; of these, twenty-one or perhaps twenty-three are ranked as distinct species, and would commonly be assumed to have been here created ; yet the close affinity of most of these birds to American species is manifest in every character, in their habits, gestures, and tones of voice. So EVOLUTION AND DISTRIBUTION OF ANIMALS. 317 it is with, the other animals and with a large proportion of the plants. . . . The naturalist, looking at the inhabitants of these volcanic islands in the Pacific, feels that he is standing on Ameri- can land." The question, then, is this : If these species have been created as we find them on the Galapagos, why is it that they should all be very similar in type to other animals, living under wholly dif- ferent conditions, but on a coast not so very far away ? And again, why are the animals and plants of another cluster of vol- canic islands — the Cape "Verde Islands — similarly related to those of the neighboring coast of Africa, and wholly unlike those of the Galapagos ? If the animals were created to match their condi- tions of life, then those of the Galapagos should be like those of Cape Verde, the two archipelagoes being extremely alike in re- spect to soil, climate, and physical surroundings. If the species on the islands are products of separate acts . of creation, what is there in the nearness of the coasts of Africa or Peru to influence the act of creation so as to cause the island species to be, as it were, echoes of those on shore ? If, on the other hand, we should adopt the obvious suggestion that both these clusters of islands have been colonized by immi- grants from the mainland, the fact of uniformity of type is ac- counted for, but what of the difference of species ? If the change of conditions from continent to island may on the island cause such great and permanent changes as to form new species from the old, why may not like changes take place on the mainlands as well as on the islands ? And if possible on the mainland of South America, what evidence have we that species are perma- nent anywhere ? May they not be constantly changing ? May not what we now consider as distinct species be only the present phase in the changing history of the series of forms which consti- tutes the species ? The study of these and many similar facts can lead to but one conclusion : These volcanic islands rose from the sea destitute of land life. They were settled by the waifs of wind and of storm, birds and insects blown from the shore by trade winds, lizards carried on drift-logs and floating vegetation. Of these waifs few came per- haps in any one year, and few perhaps of those who came made the islands a home ; yet, as the centuries passed on, suitable inhab- itants were found. That this is not fancy we know, for we have the knowledge of many similar transfers. Every one who has approached our eastern shores by sea in the face of a storm will realize this. Hosts of land birds — sparrows, warblers, chickadees, and even woodpeckers — are carried out by the wind, a few fall- ing exhausted on the decks of ships, a few others falling on 3 i8 THE POPULAR SCIENCE MONTHLY. off-shore islands, like the Bermudas, the remainder drowned in the sea. Of the immigrants to the Galapagos the majority doubtless die and leave no sign. A few will remain, multiply, and take pos- session, and their descendants are thus native to the islands. But, isolated from the great mass of their species and bred under new surroundings, these island birds come to differ from their parents and still more from the great mass of the land species of which their ancestors were members. Separated from these, their indi- viduality would assert itself. They would assume with new envi- ronment new friends, new foes, new conditions. They would de- velop qualities peculiar to themselves— qualities intensified by isolation. " Migration/' says Dr. Coues, " holds species true ; localization lets them slip/' This would be more exactly the truth should we say that localization holds peculiarities true; migration lets them slip. Local peculiarities disappear by wide association and are intensified when individuals of similar peculiarities are kept together. Should later migrations of the original land species come to the islands, the individuals surviv- ing would in time form distinct species, or more likely, mixing with the mass of those already arrived, their special characters would be lost in those of the majority. The Galapagos, first studied by Mr. Darwin, serve to us only as an illustration. The same problems come up in one guise or another in all questions of geographical distribution, whether of continent or island. The relations of the fauna of different regions are intimate in direct relation to the ease by which barriers may be crossed. Dis- tinctness is in direct proportion to isolation. What is true in this regard of the fauna of any region as a whole is likewise true of any of its individual species. The degree of resemblance among individuals is in direct proportion to the freedom of their move- ment, and variation within what we call specific limits is again proportionate to the barriers which prevent equal and perfect dif- fusion. The various divisions or realms into which the surface of the earth may be divided on the basis of the differences in animal life each has its boundary in the obstacles offered to the spread of the average animal. Each species broadens its range as far as it can. It struggles knowingly or not to overcome the barriers of ocean or river, of mountain or plain, of woodland or desert, of moist- ure or drought, of cold or heat, of lack of food or abundance of enemies, whatever these barriers may be. Were it not for these barriers, every species would become what only man now is, prac- tically cosmopolitan. Man is pre-eminently the barrier-crossing animal. The degree of hindrance offered by any barrier to the EVOLUTION AND DISTRIBUTION OF ANIMALS. 319 extension of species is only relative. That which constitutes an impassable barrier to some gronps is a high-road to others. The river which opposes the passage of the monkey or the cat would be the king's highway to the frog or the turtle. The waterfall which checks the ascent of the fish would be the chosen home of the ouzel. In spite of the great variety among the barriers existing on the earth, we may divide the globe roughly into five realms or areas of distribution, having their boundaries in the sea or in differences of climate. One or two of these realms are sharply defined ; the others are surrounded by a broad fringe of debatable ground, which forms a region of transition to some other zone. The largest of these realms is the holarctic realm, which com- prises nearly all of Asia, Europe, and North America, the arctic and north temperate zones. The north temperate zone has prac- tically a continuous climate, the chief variations being in eleva- tion and rainfall. The close union of Alaska to Siberia forms an almost unbroken land area from the eastern coast of America around to western Europe. To the south the species increase in number and variety ; the arctic regions are remarkable for what they lack, yet the general character of the life is almost unbroken over this vast district. Alfred Kussel Wallace refers to this unity of northern life in these words : " When an Englishman travels by the nearest sea route from Great Britain to northern Japan, he passes by countries very unlike his own both in aspect and in natural productions. The sunny isles of the Mediterranean, the sands and date-palms of Egypt, the arid rocks of Aden, the cocoa-groves of Ceylon, the tiger-haunted jungles of Malacca and Singapore, the fertile plains and volcanic peaks of Luzon, the forest-clad mountains of For- mosa, and the bare hills of China pass successively in review, until after a circuitous journey of thirteen thousand miles he finds him- self at Hakodadi in Japan. He is now separated from his start- ing-point by an almost endless succession of plains and mountains, arid deserts or icy plateaus ; yet, when he visits the interior of the country, he sees so many familiar natural objects that he can hardly help fancying he is close to his home. He finds the woods and fields tenante'd by tits, hedge-sparrows, wrens, wagtails, larks, redbreasts, thrushes, buntings, and house-sparrows, some abso- lutely identical with our own feathered friends, others so closely resembling them that it requires a practiced ornithologist to tell the difference. . . . There are also, of course, many birds and in- sects which are quite new and peculiar, but these are by no means so numerous or conspicuous as to remove the general impression of a wonderful resemblance between the productions of such remote islands as Britain and Yesso " (Island Life). 3 2o THE POPULAR SCIENCE MONTHLY. A journey to the southward from Britain or Japan or Illinois, or any point within the holarctic realm, would show the success- ive changes in the character of .life, though gradual, to be more rapid. The barrier of frost which keeps the fauna of the tropics from encroaching on the northern regions once crossed, we come on the multitude of animals whose life depends on sunshine, the characteristic forms of the neotropical realm. The neotropical realm includes South America, the West In- dies, and the hot coast-lands of Mexico and Central America. To the northward, this realm overlaps the holarctic in the transition regions of Sonora, Arizona, Texas, and Florida ; but to the south- ward the barrier of the broad ocean keeps it practically distinct from all others. The richness of this fauna in forms and species makes the great forests of the Amazon the dream of the natural- ist. Joaquin Miller gives a vivid picture of the life of tropical America : Birds hung and swung, green-robed and red, Or drooped in curved lines dreamily, Rainbows reversed from tree to tree, Or sang — low hanging overhead, Sang soft as if they sang and slept, Sang low like some far waterfall, And took no note of us at all. Corresponding to the neotropical realm in position, but with a less rich and varied fauna, is the Ethiopian realm. This includes the greater part of Africa, merging gradually on the north into the holarctic realm, through the transition regions of Barbary, Italy, and Spain. In monkeys, herbivorous mammals, and reptiles, this region is wonderfully rich. In variety of birds and fishes the neotropical region far surpasses it. The Indian realm comprises southern Asia and the neighbor- ing islands. Its rich fauna has much in common with that of Africa, and it is, moreover, surrounded by transition districts which lead on the north to the holarctic, and on the west to the Ethiopian. On the east the Indian realm is lost in the islands of Polynesia, which represent each one its own degree of transition and isolation. The Australian realm of Australia and its islands is more iso- lated than any of the others. It shows a singular development of low types of life, as though in the progress of evolution this con- tinent had been left a whole geological age behind the others. It is certain that, could the closely competing fauna of the holarctic or Indian realms have been able to invade Australia, the dominant mammals and birds of that region would not have been marsu- pials and parrots. In the words of Prof. Bergen, "the antiquated forms of life are found in abundance only in regions where they EVOLUTION AND DISTRIBUTION OF ANIMALS. 321 have been long shut off from communication with the great land masses." The rapid multiplication which certain holarctic ani- mals and plants have shown when transported to the Australian realm, demonstrates what might have taken place if impassable barriers had not previously shut them out. Each of these great realms may be indefinitely subdivided into provinces and sections, for there is no end to the possibility of analysis. No township or school district has exactly the same animals or plants as any other ; and, finally, in ultimate analysis no two animals or plants are alike. Modification comes with the growth of each new individual, and steadily increases with the individual's separation in time or space from the parent stock. Moreover, we observe apparent anomalies of distribution in every realm : here appears an animal, there a plant, which seems to have a character or a place which it ought not to hold. To the result of unexpected or chance crossing of barriers these apparent anom- alies in geographical distribution are due. Anomalies in distri- bution, like anomalies in evolution, would cease to be such if we knew all the facts and circumstances of their previous history. The present range of the tapir in Farther India and in the north- ern part of South America, two widely separated regions, is at first sight an anomaly of distribution. This anomaly disappears when we know that formerly the tapir ranged over the holarctic realm and became gradually extinct with the changing climate. The bones of a tapir, much like one of the South American species, are found in recent clays in Indiana (Ellettsville), and similar re- mains exist in France, in China, and in Burmah. The isolated, unexterminated colonies are now left at the extremes of the ani- mal's former range, and these colonies at present constitute what we call distinct species. The more extended are our studies the fewer are the anomalies which arrest our attention, and the fewer are the distinctive or characteristic forms. There is little foundation for the current belief that each species of animal has originated in the area it now occupies, for in many cases our knowledge of paleontology shows the reverse of this to be true. Even more incorrect is the belief that each species occupies the district or the surroundings best fitted for its habitation. This is manifest in the fact of the extraordinary fertility and persistence shown by many kinds of animals and plants in taking possession of new lands, which have become, through the voluntary or involuntary interference of man, open to their invasion. Facts of this sort are the " enor- mous increase of rabbits and pigs in Australia and New Zealand, of horses and cattle in South America, and of the sparrow in North America, though in none of these cases are the animals natives of the countries in which they thrive so well " ("Wallace). 322 THE POPULAR SCIENCE MONTHLY. The persistent spreading of European weeds to the exclusion of our native plants is a fact too well known to every farmer in America, The constant movement westward of the white- weed and the Canada thistle marks the steady deterioration of our grass -fields. Especially noteworthy has been this change in Australia and New Zealand. In New Zealand the weeds of Europe, toughened by centuries of struggle, have won an easy victory over the native plants. Edward Wakefield, in his history of New Zealand, says that " many animals and birds acquire peculiarities in the new country which would indeed astonish those accustomed to them in the old. They usually run to a much larger size and breed oftener. They also take to strange kinds of food. Birds deemed granivorous at home become in- sectivorous here, and vice versa. Some learn the habits of the native species. Skylarks imitate the native wagtail, and may often be seen perching on fences and telegraph wires. They sing in the night-time, too, a thing unheard of in the old country, and doubtless acquired from the nocturnal habits of New Zealand birds." The European house-fly in New Zealand has completely extir- pated the large blue-bottle fly which was formerly a source of great annoyance to the settlers. An account is given of a farmer who filled a bottle with house-flies and carried them eighty miles into the country, liberating them one by one, in the vicinity of his sheep-folds, in order to let them take the place of the native flies. It is said that red clover would not grow in New Zealand un- til bumble-bees were introduced to fertilize its flowers. "Wake- field estimates that the introduction of these large wild bees has been worth five million dollars to the farmers in New Zealand. Dr. Hooker states that, in New Zealand, " the cow-grass has taken possession of the road-sides ; dock- and water-cress choke the rivers, the sow-thistle is spread all over the country, growing luxuriantly up to six thousand feet ; white clover in the mount- ain districts displaces the native grasses," and the native (Maori) saying is, ' ' As the white man's rat has driven away the native rat, as the European fly drives away our own, and the clover kills our fern, so will the Maoris disappear before the white man himself" (E. L. Youmans). As among some characteristic survivals of the Celts in Hampshire, England, Mr. T. W. Shore mentions the round huts of the charcoal-burners, resembling those which were common in the Celtic period; the art cf osier-working or basket-making ; the mounds on which many ancient churches are built, which were probably sacred sites of those people ; and the peculiar orientation of many churches twenty degrees north of east, which is supposed to have been derived from the pagan Celtic reverence for the May-day sunrise. CONCERNING CORPORATION LAW. 323 CONCERNING CORPORATION LAW. By AMOS G. WARNER, PROFESSOR OF ECONOMIC AND POLITICAL SCIENCE IN THE UNIVERSITY OF NEBRASKA.. IF ten Americans desire to engage in ten distinct business enter- prises, it is conceivable that they will incorporate ten joint- stock companies, and each, belong to all of them. While other countries have granted the privilege of existence to private cor- porations with extreme caution, if not reluctance, the many Legis- latures of the United States have vied with one another in making it easy for them to be born. To adapt words heretofore applied to another matter : " The whole system of the free incorporation of private companies in the United States, with all its excellences and all its defects, is thoroughly characteristic of the American people. It grew up untrammeled by any theory as to how it ought to grow, and developed with mushroom rapidity." We have no " system " of corporation law in this country ; we have, instead, a tangled mass of statutes, which is yet further amended and ensnarled at the recurring sessions of our various Legislatures. We have a still larger mass of judicial decisions, which all the ingenuity and industry of the many writers on the subject can never quite systematize and reduce to order. Even when this feat may be approximately accomplished for a moment, the growth of judge-made law is so rapid that any treatise is speedily out of date. A redeeming feature of the situation is that the mimetic tendencies of our States lead the new ones to follow the examples set by the older, and thus a certain degree of uni- formity is introduced into the different codes of law. The many sources of legislation also make it possible that a large amount of experimenting may be done without danger to the country as a whole. The immediate and disastrous consequences of the Granger railroad laws were thus limited to a few States in the Northwest, while their more general influence, as examples of what can but should not be done, has been of use to the whole country. One railroad president has gone so far as to say that in their results these laws have made a solution of the railroad prob- lem possible. The diversity of regulation has two effects — one commend- able, the other not. The first is that when companies do busi- ness in all or many of the States at once, and in any line, like that of insurance, where ascertained corporate soundness is the best advertisement, a good code of laws in any one State makes the fact that a company does business there a helpful recom- mendation. The Massachusetts law regulating insurance is an 3 24 THE POPULAR SCIENCE MONTHLY, example of this. Its stringent requirements do not hamper the companies of that State, but are, on the other hand, an introduc- tion and a guarantee that distinctly aid the Massachusetts com- panies when they carry their operations into other common- wealths. The same influence is apparently at work in the case of mortgage investment companies ; a few of the "best established among them priding themselves on complete and ostentatious compliance with the rigid but wise laws regarding publicity of accounts. The second effect of the diverse rules regarding corporations in the different States operates in an exactly opposite direction. Since it is quite well established that a corporation may incor- porate in one State and do all its business in another or others, there is a tendency for dishonest companies to take out charters in that State which bothers them with the fewest restrictions. A charter granted by the Legislature of Pennsylvania incorporating a company to do business in any State except Pennsylvania was held to be void; the Kansas court holding that no interstate comity permitted one commonwealth "to spawn corporations" upon other States which it would not allow to operate within its own borders. But the same thing is accomplished if a State, by a general act, permits companies to organize without specifying the place of business. Under some laws one corporation is not allowed to hold the stock of another ; but, on the other hand, there are States that will willingly incorporate a company for the ex- press purpose of holding the stocks of other companies. This is a very convenient fact when a " trust " is to be formed. A State noted for the laxity of its laws in this regard can serve as the birthplace of any number of companies. At present, according to Mr. W. W. Cook, " the snug harbor of roaming and piratical corporations is the little State of West Virginia. Under its laws a corporation may be created for any purpose for which a part- nership may be formed, except speculation in land ; the capital stock may be five millions of dollars or less ; there is no tax ex- cept fifty dollars annually ; residents or non-residents, aliens or citizens, may be directors; the principal place of business and directors' or stockholders' meetings may be in or out of the State ; there is no liability of directors or stockholders except on unpaid subscriptions, and no public reports are required. . . . The incor- poration of companies for the purpose of enabling them to do all their business in other States seems to be one of the chief indus- tries of West Virginia." States can only guard themselves against the invasion of hordes of these irresponsible artificial persons by strict statutory regulation of " foreign corporations," but for the most part they have not taken any general precautions of this character. CONCERNING CORPORATION LAW. 325 Besides the defects in the corporation law of the United States which originate in its formless heterogeneity, there are other spe- cific evils quite generally present, which it seems not impossible to lessen. It is the purpose of this rJaper to present suggestions, drawn from the experience of this and other countries, regarding four points that seem to be of strategic importance in the reform of corporation law : 1. The prevention of "frauds in founding" (Grundungs- schwindeln). It is a suggestive fact that we have in English no recognized equivalent of the German word here parenthetically introduced. Neither is the English term " promoters " commonly used by American writers. Our examination of the problems of corporate management has been so superficial that we must make or borrow a nomenclature when we wish to discuss the evils con- nected immediately with the creation of companies. Yet a large portion of the evils connected with the existence of corporations originate at just this point. Men organize companies, at times, for the sole purpose of unloading upon them an unprofitable busi- ness. Let the experience of Eastern capitalists with Western mining stocks be put in evidence, and no one will question this statement. Mining companies with a nominal capital of fifty million dollars that have never declared a dividend are not un- common ; and very frequently the stock of mammoth companies sells at one cent on the dollar for some time before it becomes worthless. But the experience in mining is only an extreme case of what takes place in many departments of industry. In England, turning thither solely because the facts have there been made accessible and have not in this country, it is found that certain men make a business of acting as " promoters." They are skilled in the writing of prospectuses of companies, and know all the arts by which stock can be sold. They devote their energies especially to small companies and small investors. For a time their activity was turned largely to organizing " single- ship companies," the shares of which could be placed among country parsons, serving- women, and other classes of small in- vestors likely to know very little about commerce, and therefore likely to believe anything a well-printed " prospectus " might tell them. Many of these small companies never went so far as to build even a single ship, but enough ships were built by them to materially increase the number of " ocean tramps," and to call for much adverse criticism from the committee appointed "to in- vestigate the loss of life at sea." The " commission appointed to inquire into the depression of trade " also had much to say of the influence of the creation of such great numbers of limited liability companies, of the direct loss to investors, and of the general de- moralization of trade resulting from it. In fact, many English 326 THE POPULAR SCIENCE MONTHLY. investigators have laid great emphasis on the idea that over- speculation is due largely to the formation of joint-stock com- panies that have no real excuse for existence except the further- ance of the personal aims of the " promoters." It is a little curi- ous that, among the three hundred real or alleged causes of " hard times/' brought to the attention of our National Bureau of Labor, the reckless creation of limited liability concerns was not men- tioned. In 1886 a writer estimated that there were afloat in the English stock market fully two billion pounds of speculative securities, of which at least a fourth were mere gambling count- ers. It is to such a state of things that a recent law review at- tributes the fact that real investors now shun the stock exchange, and speculative operators are compelled to live on the plan of " dog eat dog." The stock exchanges of this country have had a somewhat similar experience, and the self-limiting nature of the speculation fever is indicated by the fall in value of a place in the Chicago Stock Exchange of three thousand dollars within a few years. As yet few steps have been taken to restrain the incorporation of absurd or fraudulent companies. Wasteful and semi-piratical paralleling of railroad lines is encouraged ; incipient railroads are preyed upon by construction companies ; companies of all sorts are bound hand and foot by the contracts entered into by an initial board of directors, and are brought into existence that they may be so bound. None of the leading commercial countries seem to be quite satisfied with the attempts they have made to remedy such evils as these. Germany allows definite payment from the corporation funds for the trouble and expense properly incurred by the men who organize a joint-stock company, but guards very carefully against the illicit gains too often made by "promoters." The pro- visions for registering new companies are especially stringent in all cases where a private business or factory is to be sold to a cor- poration organized to buy and manage it. The fullest possible publicity is sought regarding all the initial acts of a new com- pany, and some matters where the first decision must be final are reserved for a second meeting of the stockholders. Shares may run either to " bearer " or to a particular name. The latter can not be issued for a less amount than fifty thaler per share and the former for less than one hundred thaler per share. By forbidding the issue of shares of less amount; it is hoped to make investors consider more carefully the subject of investing, and to prevent the floating of small shares in worthless companies among the class of very small investors, who are most likely to be swindled. Some companies designed to engage in what are considered espe- cially hazardous enterprises are forbidden to issue shares of less CONCERNING CORPORATION LAW. 327 than one thousand marks each. The opinion of the United States consul-general at Frankfort-on-the-Main is that all these restrictions have not availed to prevent a regular "incorpora- tion fever," from which he expects 'very disastrous results ere long. In France there has been some agitation in favor of returning to the old system in operation till' 1863 of " special concessions r by which the right to organize a joint-stock company was a favor granted by the Government, and not a right conferred by general statute. The weight of authority and influence is, however, against this retrograde movement. Leroy-Beaulieu, in consid- ering it, recalls the fact that the prefect of police of Louis Phi- lippe refused Leclaire permission to organize the great profit- sharing company which was afterward established with signal success and which still bears his name. Leroy-Beaulieu adds, " We can bear the guardianship of law, but not of government." Certainly there should be no wish in this country to go back to the old system of special legislative charter, under which men made a business of lobbying for charters which were afterward sold to the highest bidder. One of the things upon which we can especially congratulate ourselves is of having got rid of this old source of legislative corruption, which gave us our wild-cat banks, and numberless other reasons for dreading it. Our own experience may help us in dealing with frauds in founding if we will stop to consider the difference between the old State banks and our present national banks. The greater security of the latter comes largely from detailed legislation which prescribes the conditions under which artificial persons, designed for the transaction of a given business, will be permitted to be born. What we need at present as regards miscellaneous corporations is fuller knowledge of all the facts connected with their history, and especially of their genesis. Massachusetts is the only State that has collected statistics of private corporations at all comparable with those of the English register of joint-stock companies. Most of the States provide that all new corporations shall register with more or less fullness ; but this is either a mere formality negligently performed, or else its sole object is to bring the corporation within reach of the tax-gatherer. The record is usually not published, or in some cases, as in Ohio, there is no way to trace in the published returns the outcome of the enterprises whose beginning is chronicled. In fact, our greatest need in pre- venting frauds in founding, as in preventing most other evils con- nected with corporate management, is completer publicity, and, as one result of this, fuller statistical data. 2. The proper regulation of the borrowing power. It has been stated on good authority, but is not true, that the evils of 328 THE POPULAR SCIENCE MONTHLY. corporate management of property began when it was found that corporations could borrow. Abuse of the borrowing power is cer- tainly a very common sin among artificial persons, and especially among American railways. When the holders of a small amount of stock, only partially paid in, build a road with borrowed money, the limitation of their liability shields them from personal loss ; while their power of voting themselves salaries, and of concluding profitable contracts either with themselves or friends, gives them great opportunities for personal profit irrespective of the success of the road. The last report of the statistician of the Interstate Commerce Commission shows that many of the minor and branch lines of the country have been built wholly with borrowed money —that is, they are bonded to their full cost value. Many of the longer and independent roads are bonded at half to three fourths of their entire capitalization. The total bonded debt of the rail- roads of the United States is actually greater than the total of their share capital ; and this, although the amount of water in the stocks is much larger than in the bonds. As the possession of the majority of the stock gives control over all the capital invested in the roads, it follows, from the figures given in the statistician's report, that the ownership of 81,932,234,128, or 2377 per cent of the total railway capital, insures complete direction over $8,129,787,731 of railway capital, or 136,883*53 miles of line. Massachusetts law forbids the bonding of a road to an amount exceeding the total of paid-up share capital, and this regulation is being introduced by other States. To forbid the issue of bonds that must be sold below par has been found to limit unsatisfactorily legitimate enterprises, but the effect of such a regulation is thought to be good if applied with care to specific classes of corporations. As to what is best in this matter, as in those that have gone before, we need more definite information. 3. How to secure a more representative and more responsible directorate. In regard to the election of directors it may be said that one device to prevent the tyranny of a majority of the stock- holders has been frequently tried, and another frequently recom- mended. The former plan is to limit the number of votes which any one person may cast. In Massachusetts no person except a municipal corporation can vote over one tenth of the capital stock of a railroad corporation. The trouble with this plan, and the variations of it that have been tried, is that evasion is too easy. Dummy stockholders are very easy to manufacture, and it is diffi- cult to unmask them. The much-recommended device for accom- plishing a similar purpose is that of cumulative voting. By this device a shareholder is allowed to cast as many votes for any one director as the number of his shares, multiplied by the number of directors to be elected at the given time. Nebraska has a provision CONCERNING CORPORATION LAW. 329 of this sort in her Constitution, but the domestic corporations in the State have not had a sufficient development to thoroughly test its influence. It will probably do but little good to secure minori- ty representation on the board of directors, unless the laws are so drawn as to limit the tyranny of a majority of the directors. The State of Maryland and the city of Baltimore have derived but scant benefit from their privilege of appointing a minority of the directors of the Baltimore and Ohio Railroad. But if minority representation be backed by the proper legislation governing the actions of the directors, there is no doubt that it is an efficient way of checking the misdeeds of stock majorities. . In Germany there is a second body chosen, under special rules, by the stockholders, known as the board of supervisors (Auf- sichtsrath). This board has the fullest possible power of inves- tigation and report, but very little power of any other kind. Its usefulness must obviously depend on the rules governing its selection, since, if so chosen as to have interests wholly in common with the directors, it would be of no use as a check upon them. Turning to the question of responsibility, we find that in this country the principle of limited liability is almost invariably the same for the director as for an ordinary stockholder, though the director is personally liable for all illegal or unauthorized acts. There has been a great deal of agitation of late for the introduc- tion of the French plan of protecting ordinary stockholders by the grant of limited liability, but leaving the directors liable for the corporate debts to the full amount of their respective fortunes. The experience of France with these societes en commandite has proved that responsible men can be found to manage any legiti- mate enterprise under this plan. A recent English act permits the formation of such companies in England, but the companies decline to adopt this principle under mere permissive legislation. To make this form of organization mandatory upon certain select- ed classes of our corporations is an experiment that ought to be tried, and is much better than going back to the old plan of un- limited liability for stockholders, as California has done. Under the head of the responsibility of the directors must also be treated the question of the relation of the corporation to its employe's. Albert Fink one day called together the presidents of certain roads he was trying to organize for their mutual good, and told the gentlemen who responded to his call that he wanted them all to resign. He further explained that this was advisable in order that their general freight agents might thereafter be nominally, as then actually, in charge of the several properties. The Interstate Commerce Association went down very largely be- cause the " gentlemen " who were partners to the agreement could vol. xxxvii. — 25 33 o THE POPULAR SCIENCE MONTHLY. not or would not control their subordinates. Part of this alleged powerlessness is no doubt assumed that the head may escape re- sponsibility for the action of the members, but part of it is quite certainly genuine. The development in bulk of the ponderous artificial beings has exceeded the development of their nervous sys- tems, and the monsters can only sprawl and plunge instead of go- ing forward to a definite end. This condition, however, is progress- ively cured by automatic processes. We have as yet no economic treatise on corporation by-laws in general, but well-recognized rules are developing for the organization of specific classes of cor- porations. In the narrower view the relation of the corporation to its em- ploye's is merely a question of wages, of strikes, and lock-outs, and of relative losses from these disturbances to employers and em- ployed. The statistics of strikes and lock-outs collected by our National Bureau of Labor show that almost the only industry in which the losses inflicted by strikes are heavier on the employers than on the men is that of transportation. The undetermined losses inflicted upon the general public by this class of strikes must be also especially large. Two ways of dealing with these evils have been tried in Europe, either of which seems to be a par- tial remedy, but neither of which seems likely to commend itself to Americans. The first is to impose a heavy per diem fine or even forfeiture of charter upon any corporation that fails to per- form its public functions. This forces the company to make terms of some kind with the strikers. When strikers in this country have tried to secure the forfeiture of charters through the courts, on the ground that the companies did not discharge their public functions, they have met with little success, though in some cases a street-car company has thought it necessary to insist on running a single car each day in order to secure its charter against at- tack on this ground. The second European method of guarding the public against the loss of strikes is to make it a misdemeanor for any employe* to quit work without giving (say) five days' no- tice. The trial of this method has been advocated in this country, but it may be doubted if our system of police could be relied on to enforce such a law, or if, at the critical time, public opinion would indorse it. That the great corporations see the necessity of acting in the matter, so as to avert the danger that continually hangs over them and the public, is seen in the rapid development of relief associations and other devices for making the position of the employe* more stable than it has ever yet been in this coun- try. The President of the Union Pacific Road has advocated the withholding from subordinate officials of the arbitrary power of dismissing the men, the object being to make the men an integral part of the corporation, and to give them security in their posi- CONCERNING CORPORATION LAW. 331 tions during good conduct, and a prospect of promotion if espe- cially efficient. The problems that our Government must con- front in the matter of civil-service reform are also to be dealt with by our corporations, and the conditions are enough alike so that the experience of each may serve for the guidance of both. 4. Adequate publicity of corporate transactions. The need of thorough publicity of corporation accounts has been already dwelt on at some length. Nearly all the abuses to which corpo- rate management of property is liable originate and wax mighty only when concealed. On the other hand, secrecy, even when it does not cloak abuses, is commonly suspected of doing so. Most of the unreasoning and unreasonable attacks on corporations have been made when those in charge of the corporations insisted on the privilege of keeping their affairs entirely to themselves. The advantages of business secrecy to the individual business man who practices it are abundantly manifest, but its advantages to the public at large, while also manifest, are countervailed by very serious disadvantages. Experience seems to have demonstrated quite conclusively that a being at once so vulnerable and so pow- erful as a corporation can not afford to keep its affairs entirely to itself, and if it could afford to do so the public can not afford to let it. There is said to be a strong tendency toward " socialism " in this wresting of business secrets from the great managers of the world's industries, and bringing the most private of business transactions to the bar of public opinion. Many will no doubt answer that " the charge is true, and we glory in its truth." Many more will be inclined to say, with the present writer, that, while this objection should be given its due force, it has not nearly force enough to overrule the strong necessities of the case. The chief danger that legitimate enterprises have to fear from com- plete publicity is that of overtaxation. The wealth of the cor- porations lying fully exposed to public view, it is so easy for the politician to fill the public coffers from that source that we already find certain classes of corporations driven out of certain States by excessive taxation. But it may be doubted whether tax- ation is as likely to be excessive when the state of a company's ac- counts is definitely known, as when the politician and his constitu- ents are free to draw upon their imaginations for the amount of wealth in the corporate coffers. In other words, it seems probable that in this country, as yet, we have less to fear from willful injus- tice than from mutual misunderstandings begotten of secrecy on the one hand, and suspicion on the other. European countries are distinctly ahead of us in this matter. They have by no means solved all the problems connected with the corporate manage- ment of property, but they have at least collected more of the data that will make a solution possible. 33 2 THE POPULAR SCIENCE MONTHLY. When, in 1873, Adolph Wagner read before the German Verein fiir Socialpolitik an elaborate paper on joint-stock companies, he made many suggestions as to the reform of corporation law. But he concluded by defending the thesis that, while the reform of corporation law was indispensable, this alone, however perfectly accomplished, could not suffice to eliminate the evils of corporate management of property ; he contended that corporations must continue to be mischievous until they are restricted to a narrower field of activity than that now occupied by them ; that the state, in its various branches, must assume control of those enterprises that are of necessity monopolies. To the interminable discussion recalled by the name of Wag- ner and the mention of his thesis it is here desired to contribute but a single suggestion. Spencer and others dwell always upon the distinction between " compulsory co-operation " through the state, which is said to be characteristic of a " militant regime" and " voluntary co-operation " through private associations, which is said to be the proper thing under an " industrial regime." ISTow, is it not true that the distinction between these two kinds of " co- operation " is fading out ? Co-operation can be wholly " volun- tary " only when isolation is a possible alternative. Is not indus- trial isolation becoming almost as impossible as political isola- tion ? Co-operation through the state is becoming less and less " compulsory " in the old significance of the term, because it is becoming more and more possible to choose what government we will live under. This comes from increased facilities, both physi- cal and legal, for moving from one state to another. Formerly, a man must obey the state under which he was born ; his " co- operation " with it was, indeed, compulsory. Now, expatriation is a comparatively simple and pleasant alternative to obedience. States and nations are coming to compete with each other for desirable citizens, as producers of services or commodities for- merly competed with each other for purchasers. There can be no doubt that Bismarck's hand was less heavy upon Germany because so many of her citizens emigrated, and so many more of them might have emigrated to this or other countries. Within the States and cities of our own republic we see our Legislatures and town councils continually coerced by considerations of at- tracting or retaining desirable classes of citizens. It is easier to escape from the power of the Legislature of Pennsylvania than from the influence of the Pennsylvania Railroad ; it is easier to get beyond the reach of the tax-gatherers of all our States than to cease to pay tribute to the Standard Oil Company or to the anthracite coal pool. The point may be restated thus: The ^coming servitude" to which we are advancing through the increasing dominance of the state will be modified by the power INSECT PESTS OF THE HOUSE. 333 of the individual to choose what state he will serve. On the other hand, industrial co-operation, in its broadest sense, is be- coming more and more compulsory ; the distinction, therefore, between "voluntary" and "involuntary" "co-operation" is of ever-lessening importance. -+++- INSECT PESTS OF THE HOUSE. By Miss MAEGAEETTE W. BEOOKS. THE various insects which infest the dwelling have been from time immemorial a trial to careful housekeepers. Just as out of doors the gardener is constantly employed in protecting plants of all kinds from the ravages of insects, so in the house there is a perpetual warfare carried on against these indoor pests. Some eat holes in our clothes, others destroy carpets and hangings, while still others are attracted by the food in our pantries and store- rooms. Unless one has watched the habits of insects and studied their development, it is hard to realize that in their mode of growth they differ from the other animals with which we are familiar. By some it is supposed that an insect grows as a bird or a cat grows — that is, by imperceptible increase in size, with no marked change in form. With this idea it is not strange that a tiny fly should be thought a young fly that will gradually grow bigger, or that a large fly should be supposed to have lived some time to have at- tained such size. It is a fact fairly well understood that moths and butterflies pass through several changes between the egg and the perfect insect, and that the caterpillar, or worm, as it is more often called, seen feeding in our gardens, or crawling over side- walks or fences in search of a convenient spot in which to under- go its transformations, will before long assume a totally differ- ent appearance ; it is not so generally known, however, that in the larger number of insects the change is nearly if not quite as great. Among the insects which infest our houses we find representa- tives of most of the various orders of insects, and a study of these forms alone would prove of interest and value. Their habits are well known to the housekeeper, and so in many cases is their ap- pearance in one or more stages ; but a history of their life from the egg to the perfect insect is still a mystery to many people, and it is to these that the following pages may be of interest. In this article attention is called only to the more common insect pests of the house. Clothes-Moth (Tinea pellionella). — One of the commonest of 334 THE POPULAR SCIENCE MONTHLY. household pests is this little moth. Most housekeepers are famil- iar with the different stages of its growth, and all are aware of the fact that it is not the little delicate silvery moth that does the damage, except indirectly by laying its eggs in our woolen garments. The moth, measuring less than half an inch across its spread wings, easily makes its way through the smallest crevices, and unless care is taken in the spring and summer we may find gar- ments that have been carefully laid away in boxes and drawers, as well as clothes hanging in closets, are infested by this creature. As a general rule, the worm deb a seems to prefer partial- Fig. 1.— Clothes-Moth, a, the moth (natural size) ; b, larva ; ly worn and Soiled gar- c, case ; d, pupa (b, c, and d are enlarged).* n , n ments to new cloth. Early in the spring garments should be well beaten and brushed to dislodge the moths or any eggs that may have been deposited in the folds of the cloth, and then hung in the air and sun for a while. When possible, garments should be folded in paper, leaving no chance for the moth to enter ; large paper bags being convenient for this purpose. Camphor-wood or red-cedar chests are valuable in protecting articles which can not easily be wrapped in paper, as the odor of these woods is disagreeable to the moth ; and when these are not to be had, oil of cedar poured on paper, which is then rolled up so that the oil shall not grease the garments, will make an ordinary box moth-proof. These rolls of paper should be scat- tered through the box and should be renewed two or three times during the spring and summer. It is said that black pepper or whole cloves sprinkled among woolen clothes will prevent the moth from depositing its eggs, as will also pieces of tallow wrapped in paper, and the odor of carbolic acid, turpentine, or benzine is very offensive to the moth. Camphor, as is well known, is beneficial in keeping away moths, but should never be placed near seal-skin, as it causes this fur to change color, show- ing streaks of gray or yellow. The great secret in taking care of furs is said to be frequent and thorough beating, the furs being kept in close closets lined with tar-paper. It has been said that the odor of tobacco is disagreeable, but in the experience of some it has seemed rather to attract than to re- * Figs. 1, 5, and 6 are from Our Common Insects, by Prof. A. S. Packard, and we are indebted to the kindness of the author for permission to use them. INSECT PESTS OF THE HOUSE. 335 pel the moths. In more than one case it was found that clothes belonging to men using no tobacco were free from the attacks of moths, while in the pockets of -those who smoked constantly were found both eggs and larvae mixed with bits of tobacco, the gar- ments having been eaten in various places. Of course, this is not an absolute proof of the inefficacy of tobacco, as there may have been other causes of attraction, and fresh, clean tobacco may, after all, be found effectual. The larvae or the eggs can be killed by putting the article in which they are found in a tightly closed vessel, and plunging it for a short time into boiling water, or it can be placed in an oven heated to a temperature of 150° Fahr. It is hardly necessary to describe the moth, which, although so small, is easily recognized as an enemy by most housewives, though in many cases little moths of various species attracted to our rooms by the lamp-light in the evening are often mistaken for the clothes-moth and destroyed. It may be well to state that the clothes-moth rarely flits about the light. Soon after the moth issues from the cocoon the female finds its way to the substance suitable for food for its young, and upon this material it lays fifty or more eggs. In about a week the egg is hatched, and almost immediately the worm begins to eat, and not only uses for food the fibers of the article upon which the egg was laid, but also makes of the material a covering for itself — a little tube in which it lives, spinning for a lining the softest silk, which it emits from glands in the head. From time to time, as the little worm grows, it enlarges its case, either by adding to the ends or by cutting with its sharp jaws little slits in the sides of the case, filling in the space between the edges with the substance nearest at hand, forming a neat patch. Not content with eating and making a shelter for itself of the cloth upon which it lives, the little worm cuts through the cloth as it makes its way in various directions, dragging its case after it. If the case is torn from it, or in any way injured, it soon makes a new one or patches the old. After a while, at the approach of warm weather, the little worm closes the ends of its case and changes to a pupa or chrysalis, and in two or three weeks the moth appears. Buffalo-Bug (Anthrenus scrophularice). — Within fifteen or twenty years there has appeared a new addition to the already long list of injurious insects introduced into this country from Europe. Although called a bug, which is the name commonly applied to all insects having inconspicuous wings, it is in reality a beetle, and why the name buffalo is applied is not known for a certainty ; some say it was first noticed in this country in the city of Buffalo, New York, while one writer says it was named from its fancied resemblance to a buffalo. Whatever may be the 33 6 THE POPULAR SCIENCE MONTHLY, reason for this name, and however inapt it may be, it is known more commonly by it than by its more proper name of " carpet- beetle." The larva which does the damage measures when full grown about three sixteenths of an inch in length. It is covered with hairs, the longest ones being on the last segment of the body, forming a sort of tail. It makes no cocoon, but when full grown remains quiet for a short time, then the skin splits along the back Fig. 2.— Cabpet-Beetle. a, larva, upper side; 6, larva, under side; c, pupa; d, perfect insect (after Riley). The straight lines at the sides show the actual length of each form. and the pupa is seen. It continues in this state for a few weeks, when the skin of the pupa bursts and the perfect insect is dis- closed — a beautiful little beetle, less than an eighth of an inch in length, marked with red, black, and white. From October until spring the beetles may be found in all stages of growth — that is to say, in the larval, pupal, and perfect states. It is found that few of the usual preventives are of any use against the attacks of this beetle, and for this reason it is a diffi- cult pest to eradicate. In some places it has proved so destructive that carpets have to be dispensed with, and in their place rugs are used, as being more conveniently examined. Tallow or tallowed paper placed around the edges of the car- pet, which are often the parts first attacked, is said to be effectual. In many cases the carpets are cut, as if with scissors, following the line of the seams in the floor, and as a remedy for this it has been recommended that the seams be filled during the winter with cotton saturated with benzine. Kerosene, naphtha, or gasoline are offensive to the beetle as well as benzine, but benzine is perhaps the simplest and safest preventive to use. It can be poured from a tin can having a very small spout, it being necessary to use but little. Before tacking down a carpet it should be thoroughly ex- amined, and if possible steamed. If in spite of precautions a car- INSECT PESTS OF THE HOUSE. 337 pet is found infested, a wet cloth, can be spread down along the edges, and a hot iron passed over it, the steam thus generated not only killing the beetles and larva?, but destroying any eggs that may have been laid. Clothing is sometimes attacked as well as objects of natural history — such as stuffed birds and mammals. It was believed that the beetle must feed on some plant, for in a number of cases it was captured out of doors, and it was finally discovered feeding on the pollen of the flowers of spiraeas, the beetle living on the plant for a while and then returning to the house to lay its eggs. When this was proved, it was suggested that spiraeas should be planted around houses infested by the beetle ; by doing this the plants could be often examined and the beetles destroyed. Cockroaches (Blattidce). — Among the Orthoptera, to which order this family belongs, we find a different mode of transforma- tion. Were it not for its small size and the absence of wings, the young would closely resem- ble the parent, and, after molting or changing its skin several times, it reach- es maturity without having passed through a stage in which it keeps perfectly quiet, as in the case of the moth and beetle. The eggs of the cockroach are carried about in a lit- tle case by the female, and when these eggs are ready to hatch, this case is dropped ; and it is said by some writers that the little ones are helped out by the mother. Just after the young come from the egg, and after each molt, they are white, but the usual color is brown or black. They molt five or six times before reaching maturity. Cockroaches are very troublesome, eating anything that comes in their way ; are unpleasant to look upon, and are specially dis- gusting to us on account of their disagreeable odor. The large cockroach (Periplaneta orienialis), or "black beetle," as it is sometimes called, might in some cases be not unwelcome, as it acts as a scavenger, keeping the corners of the rooms it fre- quents clean, and furthermore it feeds on that most disgusting of pests, the bed-bug. Though this is said in its favor, we think there is no doubt that the remedy might be thought as bad as the disease, and it would be considered more agreeable to find some other way of exterminating the bed-bug ; and most people would 25* Fig. 3. — Cockroach, a, male ; b, female. 338 THE POPULAR SCIENCE MONTHLY. prefer having their corners cleaned in the ordinary way, with soap and water ; nevertheless, it is sometimes of service in this way. This cockroach is of a dark-brown color, about an inch in length ; the male having short wings, while the female has only rudimentary wings. It is very troublesome in kitchens, coming out at night when the lights are out. A somewhat larger insect is the American cockroach (Peripla- neta americana), which is a lighter brown color, both the male and female having well-developed wings. This species is not so often found in houses, but frequents water-pipes and sewers and the cargoes of vessels. The smallest cockroach which is a pest in our houses is the "water-bug" (Ectdbia lapponica). It is also known as the " Cro- ton-bug." This insect is very common in houses in New Eng- land, and, though eating any kind of food, is especially fond of bread. It frequents bakeries, where it proves a great annoyance, sometimes being baked in the bread in spite of care. It also eats the covers of books bound in cloth, but will not touch those bound in leather. It has been said that sailors have been greatly troubled by cockroaches eating the nails of their fingers and toes, and the hard parts of their feet and hands, but this has been questioned. However, a writer in Nature affirms that while in Australia he was awakened one night by cockroaches nibbling his feet, which were badly blistered, and in the morning he found the skin had been eaten from a large blister, causing a painful sore, and that the hard skin of the heel had also been eaten. Another writer in the same journal says that this habit of cockroaches is well known to all West Indians. Borax is very disagreeable to cockroaches and will drive them away, and it is said to kill them if mixed with white sugar and sprinkled around the corners frequented by them. The following receipt for a preparation to exterminate cockroaches is given in a late number of Science : thirty-seven parts of borax, nine parts of starch, and four parts of cocoa. This preparation should be sprinkled around their haunts. Insect-powder does not kill them but renders them stupid, and while in this condition they can easily be swept up and destroyed. In England cockroaches are sometimes caught with stale beer, which is placed in a deep dish, bits of wood being so arranged that the cockroaches can climb into the liquid. The following preparations are mentioned in Harris's Insects Injurious to Vege- tation, but, as they are poisonous, they should be used with the greatest care. The first is a tablespoonful of red lead and Indian meal, mixed with enough molasses to make a thick batter ; the other is a teaspoonful of powdered arsenic mixed with a table- INSECT PESTS OF THE HOUSE. 339 spoonful of mashed potatoes. These preparations should be used for several nights in succession. Bristle-Tail or Silver-Fish (Lepisma). — Often when look- ing into a box or drawer which has remained in a damp place for some time, or on opening an old book, we see a curious little silvery creature running swiftly out of sight. It is so unlike the insects which we usually find in our houses that one hardly knows what to call it. It is nevertheless an insect, though belonging to a low order. Its long, slender body is covered with delicate iri- descent scales, from which is derived its name "silver-fish"; it has no wings and passes through no metamorphoses. It feeds on silken clothing, tapestry, and the like, but is more destructive to books, eating the paste of the binding and even the leaves, though loose papers are more often attacked. A few years ago one species was found doing a great deal of damage in museums by eating the labels. The labels which were, rendered illegible by the attacks of this insect were made of heavily sized paper, in most cases common unglazed paper remaining untouched by them ; and it was also found that only clothing finished with starch or sizing was subject to their attacks. Prof. Hagen, writing on this pest, recommends that insect-powder, which easily kills them, should be sprinkled about silk dresses or any articles liable to be' injured by them. Where papers are pressed close together the Lepisma can do no damage ; but in cases where pressure might injure the papers or pictures they might be inclosed in boxes, taking care that the covers fit so closely that no space is left for the insect to enter, or the boxes might be sealed up by pasting strips of paper around the covers, a paste with which insect-pow- der has been mixed being used for this purpose ; valuable framed engravings might be covered on the backs with common paper, the same kind of paste being used. There is no doubt that labels washed in an alcoholic solution of corrosive sublimate would be rendered proof againstr the attacks of this insect. Death- Watch (Anobium). — Books are also eaten by the larva and the mature insect of several species of beetles belonging to the genus Anobium. These beetles produce the ticking sound some- times heard in the wood-work of houses, specially noticeable at night, when everything is quiet. This sound is probably a sexual call, and is made by the beetle rapping the wood with its head. Injury is also done by them to furniture and food, and they some- times prove a great annoyance. Their depredations may be pre- vented by washing articles liable to be attacked in a solution of corrosive sublimate in alcohol, or objects such as books may be exposed to the odor of carbolic acid or benzine, or they may be fumigated with burning sulphur. There are still other insects which do more or less damage in 34 o THE POPULAR SCIENCE MONTHLY. libraries * by eating the books, but those already mentioned are the principal ones. Ants (Formic idee). — Of the large black or brownish ants that trouble us in store-rooms but little can be said, as, so far as I have examined the authorities within my reach, I have found but little mention of them. Judging by my own experience, they are very difficult pests to expel from the house. Cayenne pepper is said to be disagreeable to them, and arsenic mixed with any kind of attractive food will kill them. Oil of peppermint is found very effectual in driving them away, but everything in its vicinity is so permeated with the odor that its use can not be recommended. It is often said that borax will drive them away, but this has been tried without success ; however, according to a writer in the Popular Science News, the borax should first be heated, to deprive it of its water of crystallization. Hot alum- water is very offensive to most of the insect pests of the house, and should be applied with a brush when nearly boiling hot. Ants are extremely fond of sugar, and anything containing it will attract them. A glass of jelly left uncovered within their reach will be found tunneled in every direction, and, by pouring boiling water upon it, the ants within may be killed. An excellent and simple trap for them is a sponge wet with some sweet sirup. When the interstices of the sponge are filled with the ants, it can be carefully taken up and plunged into boil- ing water, and again set for them after saturating the sponge with the sirup. Another trap which is still more simple is a plate covered with a thin layer of lard, which should be placed in the closet frequent- ed by them. This would probably prove more effectual in catch- ing the little yellow ant (Myrmica molesta), which is sometimes very troublesome in the house. Mention should be made of the white ants, which, although resembling the true ants in appearance, really belong to the order of Neuroptera. The only species found in the United States does great damage by eating the interior of the wood-work of build- ings. These ants enter the timbers of the foundation from below, and extend their galleries to the top, leaving the outside untouched, so that their presence is unsuspected until the supports suddenly give way. Several years ago the " dungeon/' as it is called in the State- House in Boston, was found to be undermined by them, and Dr. Hagen apprehended considerable trouble if their depredations 1 Prof. Yerrill found in the library of Yale College a caterpillar belonging to the genua Angioma eating the leather bindings of old books. When ready to transform, this larva spins a silken cocoon, and after a short time there issues from it a little moth measuring half an inch across its spread wings. INSECT PESTS OF THE HOUSE, 341 were not immediately checked. In addition to the danger of the supports giving way, there was reason for alarm in the fact that they also destroy books and paper ; but in this case, fortunately, the papers stored in the part of the ' State-Honse in which they appeared were of little value. Measures were taken at the time to prevent their devastating work, and it is hoped that they have been exterminated ; but Dr. Hagen, in an article on the subject a few years later, thought it not improbable that they had spread farther, as nothing was done to prevent their entering other parts of the building. These ants feed on rotten wood, living in old stumps of trees, and sometimes in old fences, and Dr. Hagen suggested the remov- ing of every old stump around buildings and in the vicinity of cities, thus diminishing the number by depriving them of their necessary food. Places kept moist by hot steam are particularly favorable for the work of these little creatures ; and more or less trouble was occasioned in Cambridgeport, at the telescope works of Alvan Clark and Son, where a timber constantly moist from the steam was honey-combed by them ; and some years ago a bridge near Porter's Station in Cambridge was destroyed, probably from the same cause. As many trains stopped under this bridge, it was constantly moist from the steam of the locomotives. So far the insects mentioned are those that do direct injury to our clothes, carpets,* food, books, etc., but there are still others which frequent our houses and prove very annoying in various ways ; and besides these there are numerous insects which cause much trouble in collections of natural history, and in mu- seums the utmost care must be exercised to prevent their attacks. It is not often that these museum pests prove of much annoyance in the house. I have found the larva of a beetle (Attagenus pellio) in the sawdust of a doll's arm ; and the larva of another species (Attagenus megatama) is sometimes found to have eaten the feathers in pillows, and the short particles of the feathers become so firmly fastened in the ticking by the repeated shakings of the pillow that a fine, soft felting is made, resembling the fur of a mole. Bed-Bug (Cimex lectularius) . — The eggs of the bed-bug are white in color and oval in shape. The young differ but slightly from the parent. The full-grown bug is wingless or possesses rudimentary wings, is less than a quarter of an inch in length and of a brown color. It is about eleven weeks in attaining its * A brief mention may be made of a fly {Sccnopinus pallipcs) whose habits are but little known. The larva is a long, white worm living under carpets, upon which it is supposed to feed, and it is also found in rotten wood, but as yet it has not appeared in numbers suffi- ciently large to prove an annoyance in the house. The fuil-grown fly measures about a quarter of an inch in length. 34 2 THE POPULAR SCIENCE MONTHLY. growth. Dr. Packard, in his Guide to the Study of Insects, says that bed-bugs may be destroyed by " a preparation consisting of thirty parts of unpurified, cheap petroleum, mixed with a thousand parts of water" ; and in the Popular Science News was published the following formula for a bed-bug poison : Into one half pint of alcohol put one ounce of camphor, with one ounce of pulverized sal ammoniac and one ounce of corrosive sublimate ; to this add one half pint of spirits of turpentine and shake well before using. These solutions may be ap- plied around the cracks Fig. 4.-Bed-Bug. a, young; 5, adult (after Kiley), both an( J crev iceS of a bedstead; C'liltir^cd. benzine, too, may be used with good effect, and boiling water will destroy them, but the best preventive is perfect cleanliness. Curiously enough, they live parasitic upon domestic birds. Flea (Pulex cams). — The fleas, although having no wings, have until lately been classed with the flies (Diptera), but are now placed by many writers in an order by themselves, the Aphanip- tera. During the past summer and fall there has been considerable annoyance caused in and around Boston by this troublesome in- sect, and owing to its habit of attacking man it was supposed to be the true human flea, but a letter of in- quiry on the subject, addressed to an emi- nent entomologist brought the following reply : " So far as I know, we do not have the human flea in North America, and ours is Pulex canis, the dog and cat flea. It seems to breed in sandy cellars and such places at certain seasons." The eggs of this flea are laid on the dog or cat, and, being sticky, adhere to the hair until almost ready fo hatch, when they fall to the ground. These eggs are very small, white, and oblong, and but eight or ten are laid by one female. The young larvse are hatched in about a week, and their growth Fig. 5.— Flea, (much enlarged). INSECT PESTS OF THE HOUSE. 343 is usually attained in less than two weeks ; they then pass two more weeks in the pupal stage, when the perfect insect appears. When dogs are badly infested by them, the use of common olive- oil is recommended. This should be well rubbed into the hair and over the skin, being allowed to remain for half an hour, when it should be washed out with the best yellow soap and lukewarm water. Dalmatian insect-powder has also been found efficacious. This powder can be rubbed into the hair, and it can be sprinkled around their kennels. It is not, however, best to use it on cats, but possibly it might do no harm to sprinkle it around their sleeping-places. A better plan is to have the cat's bed made of shavings or some such material that can often be replaced, the old bedding being carefully taken up and burned. Some years ago there were on exhibition a number of so-called educated fleas, and it is thought by some people that the intelligence of fleas must be very great if they can be trained in this way ; but an article by Mr. W. FlG . 6.-larva op Flea. H. Dall, in the American Naturalist, a few years ago, showed that in every
