But to return to the distribution of his time in these busy days. Having passed, as we have seen, the greater part of the day in the Museum and the school, he had the hours of the night for writing, and rarely left his desk before one or two o'clock in the morning, or even later. His last two volumes of the "Contributions," upon the Acalephs, were completed during these years. In the mean time, the war between North and South had broken out, and no American cared more than he for the preservation of the Union and the institutions it represented. He felt that the task of those who served letters and science was to hold together the intellectual aims and resources of the country during this struggle for national existence, to fortify the strongholds of learning, abating nothing of their efficiency, but keeping their armories bright against the return of peace, when the better weapons of civilization should again be in force. Toward this end he worked with renewed ardor, and while his friends urged him to suspend operations at the Museum and husband his resources until the storm should have passed over, he, on the contrary, stimulated its progress by every means in his power. Occasionally he was assisted by the Legislature, and early in this period an additional grant of ten thousand dollars was made to the Museum. With this grant was begun the series of illustrated publications already mentioned, known as the "Bulletin of the Museum of Comparative Zoology in Cambridge."
During this period he urged also the foundation of a National Academy of Sciences, and was active in furthering its organization and incorporation (1863) by Congress. With respect to this effort, and to those he was at the same time making for the Museum, he was wont to recall the history of the University of Berlin. In an appeal to the people in behalf of the intellectual institutions of the United States during the early years of the war he says: "A well known fact in the history of Germany has shown that the moment of political danger may be that in which the firmest foundations for the intellectual strength of a country may be laid. When in 1806, after the battle of Jena, the Prussian monarchy had been crushed and the king was despairing even of the existence of his realm, he planned the foundation of the University of Berlin, by the advice of Fichte, the philosopher. It was inaugurated the very year that the despondent monarch returned to his capital. Since that time it has been the greatest glory of the Prussian crown, and has made Berlin the intellectual centre of Germany."
It may be added here as an evidence of Agassiz's faith in the institutions of the United States and in her intellectual progress that he was himself naturalized in the darkest hour of the war, when the final disruption of the country was confidently prophesied by her enemies. By formally becoming a citizen of the United States he desired to attest his personal confidence in the stability of her Constitution and the justice of her cause.
Some light is thrown upon the work and incidents of these years by the following letters:—
LONDON, ALBEMARLE ST., April 16, 1861.
MON CHER AGASS,* (* An affectionate abbreviation which Sir Philip often used for him.)
I have this morning received your handsome and welcome present of the third volume of your great undertaking, and this reminds me how remiss I have been in not writing to you sooner. In fact, I have had nothing worth writing about, and I know your time is too valuable to be intrenched upon by letters of mere gossip. I have not of course had time to peruse any portion of the monograph, but I have turned over the pages and seen quite enough to sharpen my appetite for the glorious scientific feast you have so liberally provided. And now that the weight is off your mind, I hope shortly to hear that you are about to fulfill this year the promise you made of returning to England for a good long visit, only postponed by circumstances you could not have foreseen. Now that you have your son as the sharer of your labors, you will be able to leave him in charge during your absence, and so divest your mind of all care and anxiety with reference to matters over the water. Here we are all fighting most furiously about Celts and flint implements, struggle for life, natural selection, the age of the world, races of men, biblical dates, apes, and gorillas, etc., and the last duel has been between Owen and Huxley on the anatomical distinction of the pithecoid brain compared with that of man. Theological controversy has also been rife, stirred up by the "Essays and Reviews," of which you have no doubt heard much. For myself, I have been busy preparing, in conjunction with Huxley, another decade of fossil fishes, all from the old red of Scotland. . .Enniskillen is quite well. He is now at Lyme Regis. . .
At about this time the Copley Medal was awarded to Agassiz, a distinction which was the subject of cordial congratulation from his English friends.
BELGRAVE SQUARE, March, 1862.
Your letter of the 14th February was a great surprise to me. I blamed myself for not writing you sooner than I did on the event which I had long been anxious to see realized; but I took it for granted that you had long before received the official announcement from the foreign secretary that you were, at the last anniversary of the Royal Society, the recipient of the highest honor which our body can bestow, whether on a foreigner or a native. . .On going to the Royal Society to-day I found that the President and Secretaries were much surprised that you had never answered the official letter sent to you on the 1st or 2nd December by the Foreign Secretary, Professor Muller, of Cambridge. He wrote to announce the award, and told you the Copley Medal was in his safe keeping till you wrote to say what you wished to have done with it. I have now recommended him to transmit it officially to you through the United States Minister, Mr. Adams. In these times of irritation, everything which soothes and calms down angry feelings ought to be resorted to; and I hope it may be publicly known that when our newspapers were reciprocating all sorts of rudenesses, the men of science of England thought of nothing but honoring a beloved and eminent savant of America.
I thank you for your clear and manly view of the North and South, which I shall show to all our mutual friends. Egerton, who is now here, was delighted to hear of you, as well as Huxley, Lyell, and many others. . .
In a paper just read to the Geological Society Professor Ramsay has made a stronger demand on the powers of ice than you ever did. He imagines that every Swiss lake north and south (Geneva, Neuchatel, Como, etc.) has been scooped out, and the depressions excavated by the abrading action of the glaciers.
ALBEMARLE ST., LONDON, March 11, 1862.
As I am now settled in London for some months, I take the first opportunity of writing to congratulate you on the distinction which has been conferred upon you by the Royal Society, and I will say that you have most fully earned it. I rejoice exceedingly in the decision the Council have arrived at. I only regret I was not on the Council myself to have advocated your high claims and taken a share in promoting your success. It is now long since I have heard from you, but this terrible disruption between the North and South has, I suppose, rendered the pursuit of science rather difficult, and the necessary funds also difficult of attainment. I should like very much to hear how you are getting on, and whether there is any likelihood of your being able to come over in the course of the summer or autumn. I fully expected you last year, and was very much disappointed that you could not realize your intention. I have this day sent to you through Bailliere, the last decade of the Jermyn St. publications.* (* Publications of the Geological Survey of England.) You will see that Huxley has taken up the subject of the Devonian fishes in a truly scientific spirit. . .
BRITISH MUSEUM, August 30, 1862.
I have received, and since its reception have devoted most of my spare moments to the study of, your fourth volume of the "Natural History of the United States,"—a noble contribution to our science, and worthy of your great name.
The demonstration of the unity of plan pervading the diversities of the Polyps, Hydroids, Acalephal and Echinodermal modifications of your truly natural group of Radiates, is to my mind perfect, and I trust that the harsh and ugly and essentially error-breeding name of Coelenterata may have received its final sentence of exile from lasting and rational zoological terminology.
I shall avail myself of opportunities for bringing myself to your recollection by such brochures as I have time for. One of them will open to your view something of the nature of the contest here waging to obtain for England a suitable Museum of Natural History, equivalent to her wealth and colonies and maritime business. In this I find you a valuable ally, and have cited from the Reports of your Museum of Comparative Zoology in support of my own claims for space.
I was glad to hear from Mr. Bates that the Megatherium had not gone to the bottom, but had been rescued, and that it was probably ere this in your Museum at Cambridge. I trust it may be so.
A line from you or the sight of any friend of yours is always cheering to me. Our friends Enniskillen and Egerton are both well. . .
I remain ever truly yours,
As has been seen by a previous letter from Sir Roderick Murchison, Agassiz tried from time to time to give his English friends more just views of our national struggle. The letter to which the following is an answer is missing, but one may easily infer its tenor, and the pleasure it had given him.
NAHANT, MASSACHUSETTS, August 15, 1862.
. . .I feel so thankful for your words of sympathy, that I lose not an hour in expressing my feeling. It has been agonizing week after week to receive the English papers, and to see there the noble devotion of the men of the North to their country and its government, branded as the service of mercenaries. You know I am not much inclined to meddle with politics; but I can tell you that I have never seen a more generous and prompt response to the call of country than was exhibited last year, and is exhibiting now, in the loyal United States. In the last six weeks nearly 300,000 men have volunteered, and I am satisfied that the additional 300,000 will be forthcoming without a draft in the course of the next month. And believe me, it is not for the sake of the bounty they come forward, for our best young men are the first to enlist; if anything can be objected to these large numbers of soldiers, it is that it takes away the best material that the land possesses. I thank you once more for your warm sympathy. I needed it the more, as it is almost the first friendly word of that kind I have received from England, and I began to question the humanity of your civilization. . .Under present circumstances, you can well imagine that I cannot think of leaving Cambridge, even for a few weeks, much as I wish to take some rest, and especially to meet your kind invitation. But I feel that I have a debt to pay to my adopted country, and all I can now do is to contribute my share toward maintaining the scientific activity which has been awakened during the last few years, and which even at this moment is on the increase.
I am now at Nahant, on the sea-shore, studying embryology chiefly with reference to paleontology, and the results are most satisfactory. I have had an opportunity already of tracing the development of the representatives of three different families, upon the embryology of which we had not a single observation thus far, and of making myself familiar with the growth of many others. With these accessions I propose next winter seriously to return to my first scientific love. . .
I have taken with me to the sea-shore your and Huxley's "Contributions to the Devonian Fishes," and also your notice of Carboniferous fish-fauna; but I have not yet had a chance to study them critically, from want of time, having been too successful with the living specimens to have a moment for the fossils. The season for sea-shore studies is, however, drawing rapidly to an end, and then I shall have more leisure for my old favorites.
I am very sorry to hear such accounts of the sufferings of the manufacturing districts in England. I wish I could foretell the end of our conflict; but I do not believe it can now be ended before slavery is abolished, though I thought differently six months ago. The most conservative men at the North have gradually come to this conviction, and nobody would listen for a moment to a compromise with the southern slave power. Whether we shall get rid of it by war measures or by an emancipation proclamation, I suppose the President himself does not yet know. I do not think that we shall want more money than the people are willing to give. Private contributions for the comfort of the army are really unbounded. I know a gentleman, not among the richest in Boston, who has already contributed over 30,000 dollars; and I heard yesterday of a shop-boy who tendered all his earnings of many years to the relief committee,—2,000 dollars, retaining NOTHING for himself,—and so it goes all round. Of course we have croakers and despondent people, but they no longer dare to raise their voices; from which I infer that there is no stopping the storm until by the natural course of events the atmosphere is clear and pure again.
Ever truly your friend,
Agassiz had now his time more at his own disposal since he had given up his school and had completed also the fourth volume of his "Contributions." Leisure time he could never be said to have, but he was free to give all his spare time and strength to the Museum, and to this undivided aim, directly or indirectly, the remainder of his life was devoted. Although at intervals he received generous aid from the Legislature or from private individuals for the further development of the Museum, its growth outran such provision, and especially during the years of the war the problem of meeting expenses was often difficult of solution. To provide for such a contingency Agassiz made in the winter of 1863 the most extensive lecturing tour he had ever undertaken, even in his busiest lecturing days. He visited all the large cities and some of the smaller towns from Buffalo to St. Louis. While very remunerative, and in many respects delightful, since he was received with the greatest cordiality, and lectured everywhere to enthusiastic crowds, this enterprise was, nevertheless, of doubtful economy even for his scientific aims. Agassiz was but fifty-six, yet his fine constitution began to show a fatigue hardly justified by his years, and the state of his health was already a source of serious anxiety to his friends. He returned much exhausted, and passed the summer at Nahant, where the climate always benefited him, while his laboratory afforded the best conditions for work. If this summer home had a fault, it was its want of remoteness. He was almost as much beset there, by the interruptions to which a man in his position is liable, as in Cambridge.
His letters show how constantly during this nominal vacation his Museum and its interests occupied his thoughts. One is to his brother-in-law, Thomas G. Cary, whose residence was in San Francisco, and who had been for years his most efficient aid in obtaining collections from the Pacific Coast.
CAMBRIDGE, March 23, 1863.
For many years past your aid in fostering the plans of the Museum in Cambridge has greatly facilitated the progress of that establishment in everything relating to the Natural History of California, and now that it has become desirable to extend our scheme to objects which have thus far been neglected I make another appeal to you.
Every day the history of mankind is brought into more and more intimate connection with the natural history of the animal creation, and it is now indispensable that we should organize an extensive collection to illustrate the natural history of the uncivilized races. Your personal acquaintance with business friends in almost every part of the globe has suggested to me the propriety of addressing to you a circular letter, setting forth the objects wanted, and requesting of you the favor to communicate it as widely as possible among your friends.
To make the most instructive collections relative to the natural history of mankind, two classes of specimens should be brought together, one concerning the habits and pursuits of the races, the other concerning the physical constitution of the races themselves.
With reference to the first it would be desirable to collect articles of clothing and ornaments of all the races of men, their implements, tools, weapons, and such models or drawings of their dwellings as may give an idea of their construction; small canoes and oars as models of their vessels, or indications of their progress in navigation; in one word, everything that relates to their avocations, their pursuits, their habits, their mode of worship, and whatever may indicate the dawn or progress of the arts among them. As to articles of clothing, it would be preferable to select such specimens as have actually been worn or even cast off, rather than new things which may be more or less fanciful and not indicate the real natural condition and habits of a race.
With regard to the collections intended to illustrate the physical constitution of the races it is more difficult to obtain instructive specimens, as the savage races are generally inclined to hold sacred all that relates to their dead; yet whenever an opportunity is afforded to obtain skulls of the natives of different parts of the world, it should be industriously improved, and good care taken to mark the skulls in such a way that their origin cannot be mistaken. Beside this, every possible effort should be made to obtain perfect heads, preserved in alcohol, so that all their features may be studied minutely and compared. Where this cannot be done portraits or photographs may be substituted.
Trusting that you may help me in this way to bring together in Cambridge a more complete collection, illustrative of the natural history of mankind than exists thus far anywhere,* (* All the ethnographical collections of the Museum of Comparative Zoology have now been transferred to the Peabody Museum, where they more properly belong.)
I remain, ever truly your friend and brother,
The following letter to Mr. Ticknor is in the same spirit as previous ones to Mr. Haldeman and others, concerning the distribution of fishes in America. It is given at the risk of some repetition, because it illustrates Agassiz's favorite idea that a key to the original combination of faunae in any given system of fresh waters, might be reached through a closer study than has yet been possible of the geographical or local circumscription of their inhabitants.
NAHANT, October 24, 1863.
Among the schemes which I have devised for the improvement of the Museum, there is one for the realization of which I appeal to your aid and sympathy. Thus far the natural productions of the rivers and lakes of the world have not been compared with one another, except what I have done in comparing the fishes of the Danube with those of the Rhine and of the Rhone, and those of the great Canadian lakes with those of the Swiss lakes.
I now propose to resume this subject on the most extensive scale, since I see that it has the most direct bearing upon the transmutation theory. . .First let me submit to you my plan.
Rivers and lakes are isolated by the land and sea from one another. The question is, then, how they came to be peopled with inhabitants differing both from those on land and those in the sea, and how does it come that every hydrographic basin has its own inhabitants more or less different from those of any other basin? Take the Ganges, the Nile, and the Amazons. There is not a living being in the one alike to any one in the others, etc. Now to advance the investigation to the point where it may tell with reference to the scientific doctrines at present under discussion, it is essential to know the facts in detail, with reference to every fresh-water basin on earth. I have already taken means to obtain the tenants of all the rivers of Brazil, and partly of Russia, and I hope you may be able to put me in the way of getting those of Spain, if not of some other country beside. The plan I propose for that country would be worthy of the Doctors of Salamanca in her brightest days. If this alone were carried out, it would be, I believe, sufficient to settle the whole question.
My idea is to obtain separate collections from all the principal rivers of Spain and Portugal, and even to have several separate collections from the larger rivers, one from their lower course, one from their middle course, and another from their head-waters. Take, for instance, the Douro. One collection ought to be made at Oporto, and several higher up, among its various tributaries and in its upper course; say, one at Zamora and Valladolid, one at Salamanca from the Tormes River, one at Leon from the Esla River, one at Burgos and Palencia from the northern tributaries, one at Soria and Segovia from the southern tributaries. If this could be done on such a scale as I propose, it would in itself be a work worthy of the Spanish government, and most creditable to any man who should undertake it. The fact is that nothing of the kind has ever been done yet anywhere. A single collection from the Minho would be sufficient, say from Orense or Melgaco. From the northern rivers along the gulf of Biscay all that would be necessary would be one thoroughly complete collection from one of the little rivers that come down from the mountains of Asturias, say from Oviedo.
The Ebro would require a more elaborate survey. From its upper course, one collection would be needed from Haro or Frias or Miranda; another from Saragossa, and one from its mouth, including the minnows common among the brackish waters near the mouth of large rivers. In addition to this, one or two of the tributaries of the Ebro, coming down from the Pyrenees, should be explored in the same manner; say one collection from Pampeluna, and one from Urgel, or any other place on the southern slope of the Pyrenees. A collection made at Barcelona from the river and the brackish marshes would be equally desirable; another from the river at Valencia, and, if possible, also from its head-waters at Ternel; another from the river Segura at Murcia, and somewhere in the mountains from its head-waters. Granada would afford particular interest as showing what its mountain streams feed. A collection from the Almeria River at Almeria, or from any of the small rivers of the southern coast of Spain, would do; and it would be the more interesting if another from the river Xenil could be obtained at or near Granada, to compare with the inhabitants of the waters upon the southern slope of the Sierra Nevada.
Next would come the Guadalquivir, from which a collection should be made at San Lucar, with the brackish water species; another at Seville or Cordova, one among the head-waters from the Sierra Nevada, and another from the mountains of the Mancha. From the Guadiana a collection from Villa Real, with the brackish species; one from Badajoz, and one from the easternmost headwaters, and about where the river is lost under ground.
The Tagus would again require an extensive exploration. In the first place a thorough collection of all the species found in the great estuary ought to be made with the view of ascertaining how far marine Atlantic species penetrate into the river basin; then one from Santarem, and another either from Talavera or Toledo or Aranjuez, and one from the head-waters in Guadalaxara, and another in Molina.
The collections made at different stations ought carefully to be kept in distinct jars or kegs, with labels so secure that no confusion or mistake can arise. But the specimens collected at the same station may be put together in the same jar. These collections require, in fact, very little care. (Here some details about mode of putting up specimens, transportation, etc.) If the same person should collect upon different stations, either in the same or in different hydrographic basins, the similarity of the specimens should not be a reason for neglecting to preserve them. What is aimed at is not to secure a variety of species, but to learn in what localities the same species may occur again and again, and what are the localities which nourish different species, no matter whether these species are in themselves interesting or not, new to science or known for ages, whether valuable for the table or unfit to eat. The mere fact of their distribution is the point to be ascertained, and this, as you see, requires the most extensive collections, affording in themselves comparatively little interest, but likely to lead, by a proper discussion of the facts, to the most unexpected philosophical results. . .Do, please, what you can in this matter. Spain alone might give us the materials to solve the question of transmutation versus creation. I am going to make a similar appeal to my friends in Russia for materials from that country, including Siberia and Kamschatka. Our own rivers are not easily accessible now.
Ever truly your friend,
Correspondence with Dr. S.G. Howe.Bearing of the War on the Position of the Negro Race.Affection for Harvard College.Interest in her General Progress.Correspondence with Emerson concerning Harvard.Glacial Phenomena in Maine.
AGASSIZ'S letters give little idea of the deep interest he felt in the war between North and South, and its probable issue with reference to the general policy of the nation, and especially to the relation between the black and white races. Although any judgment upon the accuracy of its conclusions would now be premature, the following correspondence between Agassiz and Dr. S. G. Howe is nevertheless worth considering, as showing how the problem presented itself to the philanthropist and the naturalist from their different stand-points.
PORTSMOUTH, August 3, 1863.
You will learn by a glance at the inclosed circular the object of the commission of which I am a member.
The more I consider the subject to be examined and reported upon, the more I am impressed by its vastness; the more I see that its proper treatment requires a consideration of political, physiological, and ethnological principles. Before deciding upon any political policy, it is necessary to decide several important questions, which require more knowledge for their solution than I possess.
Among these questions, this one occupies me most now. Is it probable that the African race, represented by less than two million blacks and a little more than two million mulattoes, unrecruited by immigration, will be a persistent race in this country? or will it be absorbed, diluted, and finally effaced by the white race, numbering twenty-four millions, and continually increased by immigration, beside natural causes.
Will not the general practical amalgamation fostered by slavery become more general after its abolition? If so, will not the proportion of mulattoes become greater and that of the pure blacks less? With an increase and final numerical prevalence of mulattoes the question of the fertility of the latter becomes a very important element in the calculation. Can it be a persistent race here where pure blacks are represented by 2, and the whites by 20-24?
Is it not true that in the Northern States at least the mulatto is unfertile, leaving but few children, and those mainly lymphatic and scrofulous?
In those sections where the blacks and mulattoes together make from seventy to eighty and even ninety per cent of the whole population will there be, after the abolition of slavery, a sufficiently large influx of whites to counteract the present numerical preponderance of blacks?
It looks now as if the whites would EXPLOITER the labors of the blacks, and that social servitude will continue long in spite of political equality.
You will see the importance of considering carefully the natural laws of increase and their modification by existing causes before deciding upon any line of policy.
If there be irresistible natural tendencies to the growth of a persistent black race in the Gulf and river States, we must not make bad worse by futile attempts to resist it. If, on the other hand, the natural tendencies are to the diffusion and final disappearance of the black (and colored) race, then our policy should be modified accordingly.
I should be very glad, my dear sir, if you could give me your views upon this and cognate matters. If, however, your occupations will not permit you to give time to this matter, perhaps you will assist me by pointing to works calculated to throw light upon the subject of my inquiry, or by putting me in correspondence with persons who have the ability and the leisure to write about it.
I remain, dear sir, faithfully,
NAHANT, August 9, 1863.
When I acknowledged a few days ago the receipt of your invitation to put in writing my views upon the management of the negro race as part of the free population of the United States, I stated to you that there was a preliminary question of the utmost importance to be examined first, since whatever convictions may be formed upon that point must necessarily influence everything else relating to the subject. The question is simply this: Is there to be a permanent black population upon the continent after slavery is everywhere abolished and no inducement remains to foster its increase? Should this question be answered in the negative, it is evident that a wise policy would look to the best mode of removing that race from these States, by the encouragement and acceleration of emigration. Should the question be answered, on the contrary, in the affirmative, then it is plain that we have before us one of the most difficult problems, upon the solution of which the welfare of our own race may in a measure depend, namely, the combination in one social organization of two races more widely different from one another than all the other races. In effecting this combination it becomes our duty to avoid the recurrence of great evils, one of which is already foreshadowed in the advantage which unscrupulous managers are taking of the freedmen, whenever the latter are brought into contact with new social relations.
I will, for the present, consider only the case of the unmixed negroes of the Southern States, the number of which I suppose to be about two millions. It is certainly not less,—it may be a little more. From whatever point of view you look upon these people you must come to the conclusion that, left to themselves, they will perpetuate their race ad infinitum where they are. According to the prevalent theory of the unity of mankind it is assumed that the different races have become what they are in consequence of their settlement in different parts of the world, and that the whole globe is everywhere a fit abode for human beings who adapt themselves to the conditions under which they live. According to the theory of a multiple origin of mankind the different races have first appeared in various parts of the globe, each with the peculiarities best suited to their primitive home. Aside from these theoretical views the fact is, that some races inhabit very extensive tracts of the earth's surface, and are now found upon separate continents, while others are very limited in their range. This distribution is such that there is no reason for supposing that the negro is less fitted permanently to occupy at least the warmer parts of North and South America, than is the white race to retain possession of their more temperate portions. Assuming our pure black race to be only two millions, it is yet larger than the whole number of several races that have held uninterrupted possession of different parts of the globe ever since they have been known to the white race. Thus the Hottentots and the Abyssinians have maintained themselves in their respective homes without change ever since their existence has been known to us, even though their number is less than that of our pure black population. The same, also, is the case with the population of Australia and of the Pacific islands. The Papuan race, the Negrillo race, the Australian race proper, distinct from one another, as well as from all other inhabitants of the earth, number each fewer inhabitants than already exist of the negro race in the United States alone, not to speak of Central and South America.
This being the case there is, it seems to me, no more reason to expect a disappearance of the negro race from the continent of America without violent interference, than to expect a disappearance of the races inhabiting respectively the South Sea Islands, Australia, the Cape of Good Hope, or any other part of the globe tenanted by the less populous races. The case of the American Indians, who gradually disappear before the white race, should not mislead us, as it is readily accounted for by the peculiar character of that race. The negro exhibits by nature a pliability, a readiness to accommodate himself to circumstances, a proneness to imitate those among whom he lives,—characteristics which are entirely foreign to the Indian, while they facilitate in every way the increase of the negro. I infer, therefore, from all these circumstances that the negro race must be considered as permanently settled upon this continent, no less firmly than the white race, and that it is our duty to look upon them as co-tenants in the possession of this part of the world.
Remember that I have thus far presented the case only with reference to the Southern States, where the climate is particularly favorable to the maintenance and multiplication of the negro race. Before drawing any inference, however, from my first assertion that the negro will easily and without foreign assistance maintain himself and multiply in the warmer parts of this continent, let us consider a few other features of this momentous question of race. Whites and blacks may multiply together, but their offspring is never either white or black; it is always mulatto. It is a half-breed, and shares all the peculiarities of half-breeds, among whose most important characteristics is their sterility, or at least their reduced fecundity. This shows the connection to be contrary to the normal state of the races, as it is contrary to the preservation of species in the animal kingdom. . .Far from presenting to me a natural solution of our difficulties, the idea of amalgamation is most repugnant to my feelings. It is now the foundation of some of the most ill-advised schemes. But wherever it is practiced, amalgamation among different races produces shades of population, the social position of which can never be regular and settled. From a physiological point of view, it is sound policy to put every possible obstacle to the crossing of the races, and the increase of half-breeds. It is unnatural, as shown by their very constitution, their sickly physique, and their impaired fecundity. It is immoral and destructive of social equality as it creates unnatural relations and multiplies the differences among members of the same community in a wrong direction.
From all this it is plain that the policy to be adopted toward the miscellaneous colored population with reference to a more or less distant future should be totally different from that which applies to the pure black; for while I believe that a wise social economy will foster the progress of every pure race, according to its natural dispositions and abilities, and aim at securing for it a proper field for the fullest development of all its capabilities, I am convinced also that no efforts should be spared to check that which is inconsistent with the progress of a higher civilization and a purer morality. I hope and trust that as soon as the condition of the negro in the warmer parts of our States has been regulated according to the laws of freedom, the colored population in the more northern parts of the country will diminish. By a natural consequence of unconquerable affinities, the colored people in whom the negro nature prevails will tend toward the South, while the weaker and lighter ones will remain and die out among us.
Entertaining these views upon the fundamental questions concerning the races, the next point for consideration is the policy to be adopted under present circumstances, in order to increase the amount of good which is within our grasp and lessen the evil which we may avert. This will be for another letter.
Very truly yours,
August 10, 1863.
I am so deeply impressed with the dangers awaiting the progress of civilization, should the ideas now generally prevalent about amalgamation gain sufficient ascendancy to exert a practical influence upon the management of the affairs of the nation, that I beg leave to urge a few more considerations upon that point.
In the first place let me insist upon the fact that the population arising from the amalgamation of two races is always degenerate, that it loses the excellences of both primitive stocks to retain the vices or defects of both, and never to enjoy the physical vigor of either. In order clearly to appreciate the tendencies of amalgamation, it is indispensable to discriminate correctly between the differences distinguishing one race from another and those existing between different nationalities of the same race. For while the mixture of nationalities of the same race has always proved beneficial as far as we are taught by history, the mixture of races has produced a very different result. We need only look at the inhabitants of Central America, where the white, the negro, and the Indian races are more or less blended, to see the baneful effects of such an amalgamation. The condition of the Indians on the borders of civilization in the United States and in Canada, in their contact with the Anglo-Saxons as well as with the French, testifies equally to the pernicious influence of amalgamation of races. The experience of the Old World points in the same direction at the Cape of Good Hope, in Australia; everywhere, in fact, history speaks as loudly in favor of the mixture of clearly related nations as she does in condemnation of the amalgamation of remote races. We need only think of the origin of the English nation, of that of the United States, etc. The question of breeding in-and-in, that of marriage among close relations, is again quite distinct. In fact, there is hardly a more complicated subject in physiology, or one requiring nicer discriminations, than that of the multiplication of man, and yet it is constantly acted upon as if it needed no special knowledge. I beseech you, therefore, while you are in a position to exert a leading influence in the councils of the nation upon this most important subject to allow no preconceived view, no favorite schemes, no immediate object, to bias your judgment and mislead you. I do not pretend to be in possession of absolute truth. I only urge upon you the consideration of unquestionable facts before you form a final opinion and decide upon a fixed policy. Conceive for a moment the difference it would make in future ages for the prospects of republican institutions, and our civilization generally, if instead of the manly population descended from cognate nations the United States should be inhabited by the effeminate progeny of mixed races, half Indian, half negro, sprinkled with white blood. Can you devise a scheme to rescue the Spaniards of Mexico from their degradation? Beware, then, of any policy which may bring our own race to their level.
These considerations lead me naturally to the inquiry into the peculiarities of the two races, in order to find out what may be most beneficial for each. I rejoice in the prospect of universal emancipation, not only from a philanthropic point of view, but also because hereafter the physiologist and ethnographer may discuss the question of the races and advocate a discriminating policy regarding them, without seeming to support legal inequality. There is no more one-sided doctrine concerning human nature than the idea that all men are equal, in the sense of being equally capable of fostering human progress and advancing civilization, especially in the various spheres of intellectual and moral activity. If this be so, then it is one of our primary obligations to remove every obstacle that may retard the highest development, while it is equally our duty to promote the humblest aspirations that may contribute to raise the lowest individual to a better condition in life.
The question is, then, what kind of common treatment is likely to be the best for all men, and what do the different races, taken singly, require for themselves? That legal equality should be the common boon of humanity can hardly be matter for doubt nowadays, but it does not follow that social equality is a necessary complement of legal equality. I say purposely legal equality, and not political equality, because political equality involves an equal right to every public station in life, and I trust we shall be wise enough not to complicate at once our whole system with new conflicting interests, before we have ascertained what may be the practical working of universal freedom and legal equality for two races, so different as the whites and negroes, living under one government. We ought to remember that what we know of the negro, from the experience we have had of the colored population of the North, affords but a very inadequate standard by which to judge of the capabilities of the pure blacks as they exist in the South. We ought, further, to remember that the black population is likely at all times to outnumber the white in the Southern States. We should therefore beware how we give to the blacks rights, by virtue of which they may endanger the progress of the whites before their temper has been tested by a prolonged experience. Social equality I deem at all times impracticable,—a natural impossibility, from the very character of the negro race. Let us consider for a moment the natural endowments of the negro race as they are manifested in history on their native continent, as far as we can trace them back, and compare the result with what we know of our own destinies, in order to ascertain, within the limits of probability, whether social equality with the negro is really an impossibility.
We know of the existence of the negro race, with all its physical peculiarities, from the Egyptian monuments, several thousand years before the Christian era. Upon these monuments the negroes are so represented as to show that in natural propensities and mental abilities they were pretty much what we find them at the present day,—indolent, playful, sensual, imitative, subservient, good-natured, versatile, unsteady in their purpose, devoted and affectionate. From this picture I exclude the character of the half-breeds, who have, more or less, the character of their white parents. Originally found in Africa, the negroes seem at all times to have presented the same characteristics wherever they have been brought into contact with the white race; as in Upper Egypt, along the borders of the Carthaginian and Roman settlements in Africa, in Senegal in juxtaposition with the French, in Congo in juxtaposition with the Portuguese, about the Cape and on the eastern coast of Africa in juxtaposition with the Dutch and the English. While Egypt and Carthage grew into powerful empires and attained a high degree of civilization; while in Babylon, Syria, and Greece were developed the highest culture of antiquity, the negro race groped in barbarism and NEVER ORIGINATED A REGULAR ORGANIZATION AMONG THEMSELVES. This is important to keep in mind, and to urge upon the attention of those who ascribe the condition of the modern negro wholly to the influence of slavery. I do not mean to say that slavery is a necessary condition for the organization of the negro race. Far from it. They are entitled to their freedom, to the regulation of their own destiny, to the enjoyment of their life, of their earnings, of their family circle. But with all this nowhere do they appear to have been capable of rising, by themselves, to the level of the civilized communities of the whites, and therefore I hold that they are incapable of living on a footing of social equality with the whites in one and the same community without becoming an element of social disorder.* (* I fear the expression "social equality" may be misunderstood in this connection. It means here only the relations which would arise from the mixture of the two races, and thus affect the organization of society as a whole. It does not refer to any superficial or local social rules, such as sharing on common ground public conveyances, public accommodations, and the like.—ED.)
I am not prepared to state what political privileges they are fit to enjoy now; though I have no hesitation in saying that they should be equal to other men before the law. The right of owning property, of bearing witness, of entering into contracts, of buying and selling, of choosing their own domicile, would give them ample opportunity of showing in a comparatively short time what political rights might properly and safely be granted to them in successive installments. No man has a right to what he is unfit to use. Our own best rights have been acquired successively. I cannot, therefore, think it just or safe to grant at once to the negro all the privileges which we ourselves have acquired by long struggles. History teaches us what terrible reactions have followed too extensive and too rapid changes. Let us beware of granting too much to the negro race in the beginning, lest it become necessary hereafter to deprive them of some of the privileges which they may use to their own and our detriment. All this I urge with reference to the pure blacks of the South. As to the half-breeds, especially in the Northern States, I have already stated it to be my opinion that their very existence is likely to be only transient, and that all legislation with reference to them should be regulated with this view, and so ordained as to accelerate their disappearance from the Northern States.
Let me now sum up my answer to some of your direct questions.
1st. Is it probable that the African race will be a persistent race in this country, or will it be absorbed, diluted, and finally effaced by the white race?
I believe it will continue in the Southern States, and I hope it may gradually die out at the North, where it has only an artificial foothold, being chiefly represented by half-breeds, who do not constitute a race by themselves.
2nd. Will not the practical amalgamation fostered by slavery become more general after its abolition?
Being the result of the vices engendered by slavery, it is to be hoped that the emancipation of the blacks, by securing to them a legal recognition of their natural ties, will tend to diminish this unnatural amalgamation and lessen everywhere the number of these unfortunate half-breeds. My reason for believing that the colored population of the North will gradually vanish is founded in great degree upon the fact that that population does not increase where it exists now, but is constantly recruited by an influx from the South. The southern half-breeds feel their false position at the South more keenly than the blacks, and are more inclined to escape to the North than the individuals of purer black blood. Remove the oppression under which the colored population now suffers, and the current will at once be reversed; blacks and mulattoes of the North will seek the sunny South. But I see no cause which should check the increase of the black population in the Southern States. The climate is genial to them; the soil rewards the slightest labor with a rich harvest. The country cannot well be cultivated without real or fancied danger to the white man, who, therefore, will not probably compete with the black in the labors of the field, thus leaving to him an opportunity for easy and desirable support.
3rd. In those sections where the blacks and mulattoes together make from seventy to eighty and even ninety per cent of the population will there be, after the abolition of slavery, a sufficiently large influx of whites to counteract the present numerical preponderance of blacks?
To answer this question correctly we must take into consideration the mode of distribution of the white and of the colored population in the more Southern States. The whites inhabit invariably the sea-shores and the more elevated grounds, while the blacks are scattered over the lowlands. This peculiar localization is rendered necessary by the physical constitution of the country. The lowlands are not habitable in summer by the whites between sunset and sunrise. All the wealthy whites, and in the less healthy regions even the overseers, repair in the evening to the sea-shore or to the woodlands, and return only in the morning to the plantation, except during the winter months, after the first hard frost, when the country is everywhere habitable by all. This necessarily limits the area which can be tenanted by the whites, and in some States that area is very small as compared with that habitable by the blacks. It is therefore clear that with a free black population, enjoying identical rights with the whites, these States will sooner or later become negro States, with a comparatively small white population. This is inevitable; we might as soon expect to change the laws of nature as to avert this result. I believe it may in a certain sense work well in the end. But any policy based upon different expectations is doomed to disappointment.
4th. How to prevent the whites from securing the lion's share of the labor of the blacks?
This is a question which my want of familiarity with the operations of the laboring classes prevents me from answering in a manner satisfactory to myself. Is it not possible to apply to the superintendence of the working negroes something like the system which regulates the duties of the foreman in all our manufacturing establishments?
I should like to go on and attempt to devise some scheme in conformity with the convictions I have expressed in these letters. But I have little ability in the way of organizing, and then the subject is so novel that I am not prepared to propose anything very definite.
Ever truly yours,
NEW YORK, August 18, 1863.
I cannot refrain from expressing my thanks for your prompt compliance with my request, and for your two valuable letters.
Be assured I shall try to keep my mind open to conviction and to forbear forming any theory before observing a wide circle of facts. I do not know how you got the idea that I had decided in favor of anything about the future of the colored population. I have corresponded with the founders of "La Societe Cosmopolite pour la fusion des races humaines" in France,—an amalgamation society, founded upon the theory that the perfect man is to be the result of the fusion of all the races upon earth. I have not, however, the honor of being a member thereof. Indeed, I think it hardly exists. I hear, too, that several of our prominent anti-slavery gentlemen, worthy of respect for their zeal and ability, have publicly advocated the doctrines of amalgamation; but I do not know upon what grounds.
I do, indeed, hold that in this, as in other matters, we are to do the manifest right, regardless of consequences. If you ask me who is to decide what is the manifest right, I answer, that in morals, as well as in mathematics, there are certain truths so simple as to be admitted at sight as axioms by every one of common intelligence and honesty. The right to life is as clear as that two and two make four, and none dispute it. The right to liberty and to ownership of property fairly earned is just as clear to the enlightened mind as that 5 x 6 = 30; but the less enlightened may require to reflect about it, just as they may want concrete signs to show that five times six do really make thirty. As we ascend in numbers and in morals, the intuitive perceptions become less and less; and though the truths are there, and ought to be admitted as axiomatic, they are not at once seen and felt by ordinary minds.
Now so far as the rights of blacks and the duties of whites are manifest to common and honest minds, so far would I admit the first and perform the second, though the heavens fall. I would not only advocate entire freedom, equal rights and privileges, and open competition for social distinction, but what now seems to me the shocking and downward policy of amalgamation. But the heavens are not going to fall, and we are not going to be called upon to favor any policy discordant with natural instincts and cultivated tastes.
A case may be supposed in which the higher race ought to submit to the sad fate of dilution and debasement of its blood,—as on an island, and where long continued wrong and suffering had to be atoned for. But this is hardly conceivable, because, even in what seems punishment and atonement, the law of harmonious development still rules. God does not punish wrong and violence done to one part of our nature, by requiring us to do wrong and violence to another part. Even Nemesis wields rather a guiding-rod than a scourge. We need take no step backward, but only aside, to get sooner into the right path.
Slavery has acted as a disturbing force in the development of our national character and produced monstrous deformities of a bodily as well as moral nature, for it has impaired the purity and lowered the quality of the national blood. It imported Africans, and, to prevent their extinction by competition with a more vigorous race, it set a high premium on colored blood. It has fostered and multiplied a vigorous black race, and engendered a feeble mulatto breed. Many of each of these classes have drifted northward, right in the teeth of thermal laws, to find homes where they would never live by natural election. Now, by utterly rooting out slavery, and by that means alone, shall we remove these disturbing forces and allow fair play to natural laws, by the operation of which, it seems to me, the colored population will disappear from the Northern and Middle States, if not from the continent, before the more vigorous and prolific white race. It will be the duty of the statesman to favor, by wise measures, the operation of these laws and the purification and elevation of the national blood.
In the way of this is the existence of the colored population of the Northern and Middle States. Now, while we should grant to every human being all the rights we claim for ourselves, and bear in mind the cases of individual excellence of colored people, we must, I think, admit that mulattoism is hybridism, and that it is unnatural and undesirable. It has been brought to its present formidable proportions by several causes,—mainly by slavery. Its evils are to be met and lessened as far as may be, by wise statesmanship and by enlightenment of public opinion. These may do much.
Some proclaim amalgamation as the remedy, upon the theory that by diluting black blood with white blood in larger and larger proportions, it will finally be so far diluted as to be imperceptible and will disappear. They forget that we may not do the wrong that right may come of it. They forget that no amount of diffusion will exterminate whatever exists; that a pint of ink diffused in a lake is still there, and the water is only the less pure.
Others persist that mulattoism is not and cannot be persistent beyond four generations. In other words, that like some other abnormal and diseased conditions it is self-limiting, and that the body social will be purged of it.
In the face of these and other theories, it is our duty to gather as many facts and as much knowledge as is possible, in order to throw light upon every part of the subject; nobody can furnish more than you can.
Faithfully yours,
SAMUEL G. HOWE.* (* In this correspondence with Dr. Howe, one or two phrases in Agassiz's letters are interpolated from a third unfinished letter, which was never forwarded to Dr. Howe. These sentences connect themselves so directly with the sense of the previous letters that it seemed worth while to add them.—ED.)
The Museum and his own more immediate scientific work must naturally take precedence in any biography of Agassiz, and perhaps, for this reason, too little prominence has been given in these pages to his interest in general education, and especially in the general welfare and progress of Harvard College. He was deeply attached to the University with which he had identified himself in America. While he strained every nerve to develop his own scientific department, which had no existence at Harvard until his advent there, no one of her professors was more concerned than himself for the organization of the college as a whole. A lover of letters as well as a devotee of nature, he valued every provision for a well proportioned intellectual training. He welcomed the creation of an Academic Council for the promotion of free and frequent interchange of opinion between the different heads of departments, and, when in Cambridge, he was never absent from the meetings. He urged, also, the introduction of university lectures, to the establishment of which he largely contributed, and which he would fain have opened to all the students. He advocated the extension of the elective system, believing that while it might perhaps give a pretext for easy evasion of duty to the more inefficient and lazy students, it gave larger opportunities to the better class, and that the University should adapt itself to the latter rather than the former. "The bright students," he writes to a friend, "are now deprived of the best advantages to be had here, because the dull or the indifferent must still be treated as children."
The two following letters, from their bearing on general university questions, are not out of place here. Though occasioned by a slight misconception, they are so characteristic of the writers, and of their relation to each other, that it would be a pity to omit them.
December 12, 1864.
If your lecture on universities, the first of your course, has been correctly reported to me, I am almost inclined to quarrel with you for having missed an excellent chance to help me, and advance the true interests of the college. You say that Natural History is getting too great an ascendancy among us, that it is out of proportion to other departments, and hint that a check-rein would not be amiss on the enthusiastic professor who is responsible for this.
Do you not see that the way to bring about a well-proportioned development of all the resources of the University is not to check the natural history department, but to stimulate all the others? not that the zoological school grows too fast, but that the others do not grow fast enough? This sounds invidious and perhaps somewhat boastful; but it is you and not I who have instituted the comparison. It strikes me you have not hit upon the best remedy for this want of balance. If symmetry is to be obtained by cutting down the most vigorous growth, it seems to me it would be better to have a little irregularity here and there. In stimulating, by every means in my power, the growth of the Museum and the means of education connected with it, I am far from having a selfish wish to see my own department tower above the others. I wish that every one of my colleagues would make it hard for me to keep up with him, and there are some among them, I am happy to say, who are ready to run a race with me. Perhaps, after all, I am taking up the cudgels against you rather prematurely. If I had not been called to New Haven, Sunday before last, by Professor Silliman's funeral, I should have been present at your lecture myself. Having missed it, I may have heard this passage inaccurately repeated. If so, you must forgive me, and believe me always, whatever you did or did not say,
Ever truly your friend,
CONCORD, December 13, 1864.
I pray you have no fear that I did, or can, say any word unfriendly to you or to the Museum, for both of which blessings—the cause and the effect—I daily thank Heaven! May you both increase and multiply for ages!
I cannot defend my lectures,—they are prone to be clumsy and hurried botches,—still less answer for any report,—which I never dare read; but I can tell you the amount of my chiding. I vented some of the old grudge I owe the college now for forty-five years, for the cruel waste of two years of college time on mathematics without any attempt to adapt, by skillful tutors, or by private instruction, these tasks to the capacity of slow learners. I still remember the useless pains I took, and my serious recourse to my tutor for aid which he did not know how to give me. And now I see to-day the same indiscriminate imposing of mathematics on all students during two years,—ear or no ear, you shall all learn music,—to the waste of time and health of a large part of every class. It is both natural and laudable in each professor to magnify his department, and to seek to make it the first in the world if he can. But of course this tendency must be corrected by securing in the constitution of the college a power in the head (whether singular or plural) of coordinating all the parts. Else, important departments will be overlaid, as in Oxford and in Harvard, natural history was until now. Now, it looks as if natural history would obtain in time to come the like predominance as mathematics have here, or Greek at Oxford. It will not grieve me if it should, for we are all curious of nature, but not of algebra. But the necessity of check on the instructors in the head of the college, I am sure you will agree with me, is indispensable. You will see that my allusion to naturalists is only incidental to my statement of my grievance.
But I have made my letter ridiculously long, and pray you to remember that you have brought it on your own head. I do not know that I ever attempted before an explanation of any speech.
Always with entire regard yours,
At about this time, in September, 1864, Agassiz made an excursion into Maine, partly to examine the drift phenomena on the islands and coast of that State, and partly to study the so-called "horse-backs." The journey proved to be one of the most interesting he had made in this country with reference to local glacial phenomena. Compass in hand, he followed the extraordinary ridges of morainic material lying between Bangor and Katahdin, to the Ebeene Mountains, at the foot of which are the Katahdin Iron Works. Returning to Bangor, he pursued, with the same minute investigation, the glacial tracks and erratic material from that place to the seacoast and to Mount Desert. The details of this journey and its results are given in one of the papers contained in the second volume of his "Geological Sketches." In conclusion, he says; "I suppose these facts must be far less expressive to the general observer than to one who has seen this whole set of phenomena in active operation. To me they have been for many years so familiar in the Alpine valleys, and their aspect in those regions is so identical with the facts above described, that paradoxical as the statement may seem, the presence of the ice is now an unimportant element to me in the study of glacial phenomena; no more essential than is the flesh to the anatomist who studies the skeleton of a fossil animal."
This journey in Maine, undertaken in the most beautiful season of the American year, when the autumn glow lined the forest roads with red and gold, was a great refreshment to Agassiz. He had been far from well, but he returned to his winter's work invigorated and with a new sense of hope and courage.

THE next important event in the life of Agassiz, due in the first instance to his failing health, which made some change of scene and climate necessary, is best announced by himself in the following letter.
CAMBRIDGE, March 22, 1865.
You will shed tears of joy when you read this, but such tears are harmless. Listen, then, to what has happened. A few weeks ago I was thinking how I should employ my summer. I foresaw that in going to Nahant I should not find the rest I need after all the fatigue of the two last years, or, at least, not enough of change and relaxation. I felt that I must have new scenes to give me new life. But where to go and what to do?
Perhaps I wrote you last year of the many marks of kindness I have received from the Emperor of Brazil, and you remember that at the time of my debut as an author, my attention was turned to the natural history of that country. Lately, also, in a course of lectures at the Lowell Institute, I have been led to compare the Alps, where I have passed so many happy years, with the Andes, which I have never seen. In short, the idea came to me gradually, that I might spend the summer at Rio de Janeiro, and that, with the present facilities for travel, the journey would not be too fatiguing for my wife. . .Upon this, then, I had decided, when most unexpectedly, and as the consummation of all my wishes, my pleasure trip was transformed into an important scientific expedition for the benefit of the Museum, by the intervention of one of my friends, Mr. Nathaniel Thayer. By chance I met him a week ago in Boston. He laughed at me a little about my roving disposition, and then asked me what plans I had formed for the Museum, in connection with my journey. I answered that, thinking especially of my health, I had provided only for the needs of myself and my wife during an absence of six or eight months. Then ensued the following conversation.
"But, Agassiz, that is hardly like you; you have never been away from Cambridge without thinking of your Museum."
"True enough; but I am tired,—I need rest. I am going to loaf a little in Brazil."
"When you have had a fortnight of that kind of thing you will be as ready for work as ever, and you will be sorry that you have not made some preparation to utilize the occasion and the localities in the interest of the Museum."
"Yes, I have some such misgiving; but I have no means for anything beyond my personal expenses, and it is no time to ask sacrifices from any one in behalf of science. The country claims all our resources.
"But suppose some one offered you a scientific assistant, all expenses paid, what would you say?"
"Of that I had never thought."
"How many assistants could you employ?"
"Half a dozen."
"And what would be the expense of each one?"
"I suppose about twenty-five hundred dollars; at least, that is what I have counted upon for myself."
After a moment's reflection he resumed:—
"If it suits you then, Agassiz, and interferes in no way with the plans for your health, choose your assistants among the employees of your Museum or elsewhere, and I will be responsible for all the scientific expenses of the expedition.". . .
My preparations are made. I leave probably next week, from New York, with a staff of assistants more numerous, and, I think, as well chosen, as those of any previous undertaking of the kind.* (* Beside the six assistants provided for by Mr. Thayer, there were a number of young volunteer aids who did excellent work on the expedition.)
. . .All those who know me seem to have combined to heighten the attraction of the journey, and facilitate it in every respect. The Pacific Mail Steamship Company has invited me to take passage with my whole party on their fine steamer, the Colorado. They will take us, free of all expense, as far as Rio de Janeiro,—an economy of fifteen thousand francs at the start. Yesterday evening I received a letter from the Secretary of the Navy, at Washington, desiring the officers of all vessels of war stationed along the coasts I am to visit, to give me aid and support in everything concerning my expedition. The letter was written in the kindest terms, and gratified me the more because it was quite unsolicited. I am really touched by the marks of sympathy I receive, not only from near friends, but even from strangers. . .I seem like the spoiled child of the country, and I hope God will give me strength to repay in devotion to her institutions and to her scientific and intellectual development, all that her citizens have done for me.
I am forgetting that you will be anxious to know what special work I propose to do in the interest of science in Brazil. First, I hope to make large collections of all such objects as properly belong in a Museum of Natural History, and to this end I have chosen from among the employees of our Museum one representative from each department. My only regret is that I must leave Alex in Cambridge to take care of the Museum itself. He will have an immense amount of work to do, for I leave him only six out of our usual staff of assistants. In the second place, I intend to make a special study of the habits, metamorphoses, anatomy, etc., of the Amazonian fishes. Finally, I dream sometimes of an ascension of the Andes, if I do not find myself too old and too heavy for climbing. I should like to see if there were not also large glaciers in this chain of mountains, at the period when the glaciers of the Alps extended to the Jura. . .But this latter part of my plan is quite uncertain, and must depend in great degree upon our success on the Amazons. Accompanied as I am with a number of aides naturalistes, we ought to be able among us to bring together large collections, and even to add duplicates, which I can then, on my return, distribute to the European Museums, in exchange for valuable specimens.
We leave next week, and I hope to write you from Rio a letter which will reach you about the date of my birthday. A steamer leaves Brazil once a month for England. If my arrival coincides with her departure you shall not be disappointed in this.
