Running over the t.i.tles of his courses during several consecutive years of this school instruction they read: Physical Geography and Paleontology; Zoology; Botany; Coral Reefs; Glaciers; Structure and Formation of Mountains; Geographical Distribution of Animals; Geological Succession of Animals; Growth and Development of Animals; Philosophy of Nature, etc. With the help of drawings, maps, bas-reliefs, specimens, and countless ill.u.s.trations on the blackboard, these subjects were made clear to the pupils, and the lecture hour was antic.i.p.ated as the brightest of the whole morning.
It soon became a habit with friends and neighbors, and especially with the mothers of the scholars, to drop in for the lectures, and thus the school audience was increased by a small circle of older listeners. The corps of teachers was also gradually enlarged. The neighborhood of the university was a great advantage in this respect, and Aga.s.siz had the cooperation not only of his brother-in-law, Professor Felton, but of others among his colleagues, who took cla.s.ses in special departments, or gave lectures in history and literature.
This school opened in 1855 and closed in 1863. The civil war then engrossed all thoughts, and interfered somewhat also with the success of private undertakings. Partly on this account, partly also because it had ceased to be a pecuniary necessity, it seemed wise to give up the school at this time. The friendly relations formed there did not, however, cease with it. For years afterward on the last Thursday of June (the day of the annual closing of the school) a meeting of the old pupils was held at the Museum, which did not exist when the school began, but was fully established before its close. There Aga.s.siz showed them the progress of his scientific work, told them of his future plans for the inst.i.tution, and closed with a lecture such as he used to give them in their school-days. The last of these meetings took place in 1873, the last year of his own life. The memory of it is connected with a gift to the Museum of four thousand and fifty dollars from a number of the scholars, now no longer girls, but women with their own cares and responsibilities. Hearing that there was especial need of means for the care of the more recent collections, they had subscribed this sum among themselves to express their affection for their old teacher, as well as their interest in his work, and in the inst.i.tution he had founded. His letter of acknowledgment to the one among them who had acted as their treasurer makes a fitting close to this chapter.
. . .Hardly anything in my life has touched me more deeply than the gift I received this week from my school-girls. From no source in the world could sympathy be more genial to me. The money I shall appropriate to a long-cherished scheme of mine, a special work in the Museum which must be exclusively my own,--the arrangement of a special collection ill.u.s.trating in a nutsh.e.l.l, as it were, all the relations existing among animals,--which I have deferred because other things were more pressing, and our means have been insufficient. The feeling that you are all working with me will be even more cheering than the material help, much needed as that is.
I wish I could write to each individually. I shall try to find some means of expressing my thanks more widely. Meantime I write to you as treasurer, and beg you, as far as you can do so without too much trouble, to express my grat.i.tude to others. Will you also say to those whom you chance to meet that I shall be at the Museum on the last Thursday of June, at half-past eleven o'clock. I shall be delighted to see all to whom it is convenient to come. The Museum has grown not only in magnitude, but in scientific significance, and I like from time to time to give you an account of its progress, and of my own work and aims. How much thought and care and effort this kind plan of yours must have involved, scattered as you all are! It cannot have been easy to collect the names and addresses of all those whose signatures it was delightful to me to see again. Words seem to me very poor, but you will accept for yourself and your school-mates the warm thanks and affectionate regards of your old friend and teacher.

A few months earlier than the school circular Aga.s.siz issued another prospectus, which had an even more important bearing upon his future work. This was the prospectus for his "Contributions to the Natural History of the United States." It was originally planned in ten volumes, every volume to be, however, absolutely independent, so that the completeness of each part should not be impaired by any possible interruption of the sequence. The ma.s.s of original material acc.u.mulated upon his hands ever since his arrival in America made such a publication almost imperative, but the costliness of a large ill.u.s.trated work deterred him. The "Poissons Fossiles" had shown him the peril of entering upon such an enterprise without capital. Perhaps he would never have dared to undertake it but for a friendly suggestion which opened a way out of his perplexities. Mr. Francis C. Gray, of Boston, who felt not only the interest of a personal friend in the matter, but also that of one who was himself a lover of letters and science, proposed an appeal to the public spirit of the country in behalf of a work devoted entirely to the Natural History of the United States. Mr.
Gray a.s.sumed the direction of the business details, set the subscription afloat, stimulated its success by his own liberal contributions, by letters, by private and public appeals. The result far exceeded the most sanguine expectations of those interested in its success. Indeed, considering the purely scientific character of the work, the number of subscribers for it was extraordinary, and showed again the hold Aga.s.siz had taken upon the minds and affections of the people in general. The contributors were by no means confined to Boston and Cambridge, although the Ma.s.sachusetts list was naturally the largest, nor were they found exclusively among literary and scientific circles. On the contrary, the subscription list, to the astonishment of the publishers, was increased daily by unsolicited names, sent in from all sections of the country, and from various grades of life and occupation. In reference to the character of this subscription Aga.s.siz says in his Preface: "I must beg my European readers to remember that this work is written in America, and more especially for Americans; and that the community to which it is particularly addressed has very different wants from those of the reading public in Europe. There is not a cla.s.s of learned men here distinct from the other cultivated members of the community. On the contrary, so general is the desire for knowledge, that I expect to see my book read by operatives, by fishermen, by farmers, quite as extensively as by the students in our colleges or by the learned professions, and it is but proper that I should endeavor to make myself understood by all." If Aga.s.siz, perhaps, overestimated in this statement the appreciation of the reading public in the United States for pure scientific research, it was because the number and variety of his subscribers gave evidence of a cordiality toward his work which surprised as much as it gratified him. On the list there were also some of his old European subscribers to the "Poissons Fossiles,"
among them the King of Prussia, who still continued, under the influence of Humboldt, to feel an interest in his work.
FROM HUMBOLDT TO AGa.s.sIZ.
September 1, 1856.
. . .I hear that by some untoward circ.u.mstances, no doubt accidental, you have never received, my dear Aga.s.siz, the letter expressing the pleasure which I share with all true lovers of science respecting your important undertaking, "Contributions to the Natural History of the United States." You must have been astonished at my silence, remembering, not only the affectionate relations we have held to each other ever since your first sojourn at Paris, but also the admiration I have never ceased to feel for the great and solid works which we owe to your sagacious mind and your incomparable intellectual energy. . .I approve especially the general conceptions which lie at the base of the plan you have traced. I admire the long series of physiological investigations, beginning with the embryology of the so-called simple and lower organisms and ascending by degrees to the more complicated. I admire that ever-renewed comparison of the types belonging to our planet, in its present condition, with those now found only in a fossil state, so abundant in the immense s.p.a.ce lying between the sh.o.r.es opposite to northern Europe and northern Asia. The geographical distribution of organic forms in curves of equal density of occupation represents in great degree the inflexions of the isothermal lines. . .I am charged by the king, who knows the value of your older works, and who still feels for you the affectionate regard which he formerly expressed in person, to request that you will place his name at the head of your long list of subscribers. He wishes that an excursion across the Atlantic valley may one day bring you, who have so courageously braved Alpine summits, to the historic hill of Sans Souci. . .
Something of Aga.s.siz's astonishment and pleasure at the encouragement given to his projected work is told in his letters.
To his old friend Professor Valenciennes, in Paris, he writes: "I have just had an evidence of what one may do here in the interest of science. Some six months ago I formed a plan for the publication of my researches in America, and determined to carry it out with all possible care and beauty of finish. I estimated my materials at ten volumes, quarto, and having fixed the price at 60 francs (12 dollars) a volume, thought I might, perhaps, dispose of five hundred. I brought out my prospectus, and I have to-day seventeen hundred subscribers. What do you say to that for a work which is to cost six hundred francs a copy, and of which nothing has as yet appeared? Nor is the list closed yet, for every day I receive new subscriptions,--this very morning one from California! Where will not the love of science find its niche!". . .
In the same strain he says, at a little later date, to Sir Charles Lyell: "You will, no doubt, be pleased to learn that the first volume of my new work, 'Contributions to the Natural History of the United States,' which is to consist of ten volumes, quarto, is now printing, to come out this summer. I hope it will show that I have not been idle during ten years' silence. I am somewhat anxious about the reception of my first chapter, headed, 'Cla.s.sification,'
which contains anything but what zoologists would generally expect under that head. The subscription is marvelous. Conceive twenty-one hundred names before the appearance of the first pages of a work costing one hundred and twenty dollars! It places in my hands the means of doing henceforth for Natural History what I had never dreamed of before.". . .
This work, as originally planned, was never completed. It was cut short by ill-health and by the pressure of engagements arising from the rapid development of the great Museum, which finally became, as will be seen, the absorbing interest of his life. As it stands, the "Contributions to the Natural History of the United States"
consists of four large quarto volumes. The first two are divided into three parts, namely: 1st. An Essay on Cla.s.sification. 2nd. The North American Testudinata. 3rd. The Embryology of the Turtle,--the latter two being ill.u.s.trated by thirty-four plates. The third and fourth volumes are devoted to the Radiata, and consist of five parts, namely: 1st. Acalephs in general. 2nd. Ctenophorae. 3rd.
Discophorae. 4th. Hydroida. 5th. h.o.m.ologies of the Radiates, --ill.u.s.trated by forty-six plates.* (* The plates are of rare accuracy and beauty, and were chiefly drawn by A. Sonrel, though many of the microscopic drawings were made by Professor H.J. Clark, who was at that time Aga.s.siz's private a.s.sistant. For details respecting Professor Clark's share in this work, and also concerning the aid of various kinds furnished to the author during its preparation, the reader is referred to the Preface of the volumes themselves.)
For originality of material, clearness of presentation, and beauty of ill.u.s.tration, these volumes have had their full recognition as models of scientific work. Their philosophy was, perhaps, too much out of harmony with the current theories of the day to be acceptable. In the "Essay on Cla.s.sification" especially, Aga.s.siz brought out with renewed earnestness his conviction that the animal world rests upon certain abstract conceptions, persistent and indestructible. He insists that while physical influences maintain, and within certain limits modify, organisms, they have never affected typical structure,--those characters, namely, upon which the great groups of the animal kingdom are united. From his point of view, therefore, what environment can do serves to emphasize what it cannot do. For the argument on which these conclusions are based we refer to the book itself. The discussion of this question occupies, however, only the first portion of the volume, two thirds of which are devoted to a general consideration of cla.s.sification, and the ideas which it embodies, with a review of the modern systems of zoology.
The following letter was one of many in the same tone received from his European correspondents concerning this work.
FROM RICHARD OWEN.
December 9, 1857.
. . .I cannot permit a day to elapse without thanking you for the two volumes of your great work on American zoology, which, from your masterly and exhaustive style of treatment, becomes the most important contribution to the right progress of zoological science in all parts of the world where progress permits its cultivation.
It is worthy of the author of the cla.s.sical work on fossil fishes; and such works, like the Cyclopean structures of antiquity, are built to endure. I feel and I beg to express a fervent hope that you may be spared in health and vigor to see the completion of your great plan.
I have placed in Mr. Trubner's hands a set of the numbers (6) of my "History of British Fossil Reptiles," which have already appeared; a seventh will soon be out, and as they will be sent to you in succession I hope you will permit me to make a small and inadequate return for your liberality in the gift of your work by adding your name to the list of my subscribers. . .
Believe me always truly yours,
RICHARD OWEN.
Aga.s.siz had promised himself that the first volume of his new work should be finished in time for his fiftieth birthday,--a milestone along the road, as it were, to mark his half century. Upon this self-appointed task he spent himself with the pa.s.sion dominated by patience, which characterized him when his whole heart was bent toward an end. For weeks he wrote many hours of the day and a great part of the night, going out sometimes into the darkness and the open air to cool the fever of work, and then returning to his desk again. He felt himself that the excitement was too great, and in proportion to the strain was the relief when he set the seal of finis on his last page within the appointed time.
His special students, young men who fully shared his scientific life and rewarded his generosity by an affectionate devotion, knowing, perhaps, that he himself a.s.sociated the completion of his book with his birthday, celebrated both events by a serenade on the eve of his anniversary. They took into their confidence Mr. Otto Dresel, warmly valued by Aga.s.siz both as friend and musician, and he arranged their midnight programme for them. Always sure of finding their professor awake and at work at that hour, they stationed the musicians before the house, and as the last stroke of twelve sounded, the succeeding stillness was broken by men's voices singing a Bach choral. When Aga.s.siz stepped out to see whence came this pleasant salutation, he was met by his young friends bringing flowers and congratulations. Then followed one number after another of the well-ordered selection, into which was admitted here and there a German student song in memory of Aga.s.siz's own university life at Heidelberg and Munich. It was late, or rather early, since the new day was already begun, before the little concert was over and the guests had dispersed. It is difficult to reproduce with anything like its original glow and coloring a scene of this kind.
It will no more be called back than the hour or the moonlight night which had the warmth and softness of June. It is recorded here only because it ill.u.s.trates the intimate personal sympathy between Aga.s.siz and his students.
For this occasion also were written the well-known birthday verses by Longfellow, which were read the next day at a dinner given to Aga.s.siz by the "Sat.u.r.day Club." In speaking of Longfellow's relation to this club, Holmes says "On one occasion he read a short poem at the table. It was in honor of Aga.s.siz's birthday, and I cannot forget the very modest, delicate musical way in which he read his charming verses." Although included in many collections of Longfellow's Poems, they are reproduced here, because the story seems incomplete without them.
THE FIFTIETH BIRTHDAY OF AGa.s.sIZ.
It was fifty years ago, In the pleasant month of May, In the beautiful Pays de Vaud, A child in its cradle lay.
And Nature, the old nurse, took The child upon her knee, Saying: "Here is a story-book Thy Father has written for thee."
"Come wander with me," she said, "Into regions yet untrod; And read what is still unread In the ma.n.u.scripts of G.o.d."
And he wandered away and away With Nature, the dear old nurse, Who sang to him night and day The rhymes of the universe.
And whenever the way seemed long, Or his heart began to fail, She would sing a more wonderful song, Or tell a more marvelous tale.
So she keeps him still a child, And will not let him go, Though at times his heart beats wild For the beautiful Pays de Vaud;
Though at times he hears in his dreams The Ranz des Vaches of old, And the rush of mountain streams From glaciers clear and cold;
And the mother at home says, "Hark!
For his voice I listen and yearn; It is growing late and dark, And my boy does not return!"
May 28, 1857.
Longfellow had an exquisite touch for occasions of this kind, whether serious or mirthful. Once, when some years after this Aga.s.siz was keeping Christmas Eve with his children and grandchildren, there arrived a basket of wine containing six old bottles of rare vintage. They introduced themselves in a charming French "Noel" as pilgrims from beyond the sea who came to give Christmas greeting to the master of the house. Gay pilgrims were these six "gaillards," and they were accompanied by the following note:--
"A Merry Christmas and Happy New Year to all the house of Aga.s.siz!
"I send also six good wishes in the shape of bottles. Or is it wine?
"It is both; good wine and good wishes, and kind memories of you on this Christmas Eve."
