NATHANIEL THAYER, THE FRIEND WHO MADE IT POSSIBLE TO GIVE THIS JOURNEY THE CHARACTER OF A SCIENTIFIC EXPEDITION, 5Tfje present Volume IS GRATEFULLY INSCRIBED. PREFACE. IN the winter of 1865 it became necessary for me, on account of some disturbance of my health, to seek a change of scene and climate, with rest from work. Europe was proposed ; but though there is much enjoyment for a naturalist in contact with the active scientific life of the Old World, there is little intellectual rest. Toward Brazil I was drawn by a lifelong desire. After the death of Spix, when a student of twenty years of age, I had been employed by Martius to describe the fishes they had brought back with them from their celebrated Bra- zilian journey. From that time, the wish to study this fauna in the regions where it belongs had been an ever-recurring thought with me ; a scheme deferred for want of opportunity, but never quite forgotten. The fact that the Emperor of Brazil was deeply interested in all scientific undertakings, and had expressed a warm sym- pathy with my efforts to establish a great zoological museum in this country, aiding me even by sending collections made expressly under his order for the pur- pose, was an additional incentive. I knew that the head of the government would give me every facility for my investigations. Nevertheless, tempting as was the pros- VI PREFACE. pect of a visit to Brazil, as a mere vacation it had little charm for me. Single-handed, I could make slight use of the opportunities I should have ; and though the ex- cursion might be a pleasant one for myself, it would have no important result for science. I could not forget that, had I only the necessary means, I might make col- lections on this journey which, whenever our building could be so enlarged as to give room for their exhi- bition, would place the Museum in Cambridge on a level with the first institutions of the kind. 'But for this a working force would be needed, and I saw no possibil- ity of providing for such an undertaking. While I was brooding over these thoughts I chanced to meet Mr. Na- thaniel Thayer, whom I have ever found a generous friend to science. The idea of appealing to him for a scheme of this magnitude had not, however, occurred to me ; but he introduced the subject, and, after expressing his interest in my proposed journey, added, " You wish, of course, to give it a scientific character ; take six assist- ants with you, and I will be responsible for all their expenses, personal and scientific." It was so simply said, and seemed to me so great a boon, that at first I hardly believed I had heard him rightly. In the end, I had cause to see in how large and liberal a sense he proffered his support to the expedition, which, as is usual in such cases, proved longer and more costly than was at first anticipated. Not only did he provide most liberally for assistants, but, until the last specimen was stored in the Museum, he continued to advance whatever sums were PREFACE. vii needed, always desiring me to inform him should any additional expenses occur on closing up the affairs of the expedition. It seems to me that the good arising from the knowledge of such facts justifies me in speaking here of these generous deeds, accomplished so unostentatiously that they might otherwise pass unnoticed. All obstacles thus removed from my path, I made my preparations for departure as rapidly as possible. The assistants I selected to accompany me were Mr. James Burkhardt as artist, Mr. John G. Anthony as conchologist, Mr. Frederick C. Hartt and Mr. Orestes St. John as geolo- gists, Mr. John A. Allen as ornithologist, and Mr. George Sceva as preparator. Beside these, my party was enlarged by several volunteers, to whom I was indebted for assist- ance as untiring and efficient as if they had been en- gaged for the purpose. These were Mr. Newton Dexter, Mr. William James, Mr. Edward Copeland, Mr. Thomas Ward, Mr. Walter Hunnewell, and Mr. S. Y. R. Thayer. , I should not omit to mention my brother-in-law, Mr. Thomas G. Gary, as one of my aids ; for, though not nom- inally connected with the expedition, he made collections for me at Monte Video, Buenos Ayres, and other places. I was also joined by my friends Dr. and Mrs. dotting. Dr. Cotting, like myself, was in need of a vacation, and it was his intention to remain with us for as long a time as he could spare from his professional practice. But the climate proved unfavorable to his health, and after passing a couple of months in Rio, and sharing with us all our excursions in that neighborhood, he Vlll PREFACE. ^ sailed with Mrs. Getting for Europe, where they passed the summer. His presence with us during that time was most fortunate, for it so happened that the only serious cases of illness we had among us occurred before he left, and his medical advice and care were of great service. I lost the assistance of Mr. Anthony, and Mr. Allen also, early in the expedition ; their health, always delicate, obliging them to leave for home. With these exceptions, our working force remained intact, and I am happy to state that every member of the party returned in safety to the United States.* No sooner was the Brazilian Expedition known to the public, than I received a letter from Mr. Allen McLane, President of the Pacific Mail Steamship Company, offer- ing to me and my whole party the hospitality of their magnificent ship the Colorado, then just sailing from New York for the Pacific coast. She was going almost empty of passengers, being bound by the way of Cape Horn for San Francisco. We left New York on board this beautiful vessel, on the 1st of April, 1865. The record of our delightful voyage to Rio de Janeiro will * There is but one sad record I have to make connected with this journey. My friend and companion of many years, Mr. Burkhardt, died about ten months after his return, of a disease which, though not contracted in Brazil, since it was of some years' standing, was no doubt aggravated by the hot climate. His great desire to accompany me led him, against my advice, to undertake a journey which, in his case, was a dangerous one. He suffered very much during our stay on the Amazons, but I could not persuade him to leave his work ; and in the following pages it will be seen that his industry was unflagging. PREFACE. be found in the narrative ; but I wish here publicly to acknowledge my obligation to Mr. McLane for his gener- osity to the expedition. Besides the sympathy accorded me by private individuals, I have to thank the Hon. Gideon Welles, Secretary of the Navy, for a general order, received on the eve of my departure, desiring the officers of the United States Navy, wherever I should fall in with them, to afford me such assistance in my scientific researches as would not interfere with the regular service ; and 1 learned at Rio that Mr. Seward had warmly recommended the expedition to General Webb, at that time United States Minister to Brazil. Finally, I would express my thanks also to Messrs. Garrison and Allen for the free passage offered to myself and my companions for our return, on board the line of steamers established be- tween New York and Rio de Janeiro during our stay in Brazil. It will be seen hereafter what facilities were granted me throughout this journey by the Brazilians themselves, and that the undertaking, so warmly speeded on its way, was welcomed no less cordially in the country to which it was bound. One word as to the manner in which this volume has grown into its present shape, for it has been rather the natural growth of circumstances than the result of any preconceived design. Partly for the entertainment of her friends, partly with the idea that I might make some use of it in knitting together the scientific reports of my journey by a thread of narrative, Mrs. Agassiz began this X PREFACE. diary. I soon fell into the habit of giving her daily the more general results of my scientific observations, knowing that she would allow nothing to be lost which was worth preserving. In consequence of this mode of working, our separate contributions have become so closely inter- woven that we should hardly know how to disconnect them, and our common journal is therefore published, with the exception of a few unimportant changes, almost as it was originally written. In this volume I have at- tempted only to give such an account of my scientific work and its results as would explain to the public what were the aims of the expedition, and how far they have been accomplished. It is my hope to complete a work, already begun, on the Natural History, and especially on the Fishes of Brazil, in which will be recorded not only my investigations during the journey and those of my assistants in their independent excursions, but also the researches now regularly carried on in connection with the immense Brazilian collections stored in the Museum at Cambridge. This must, however, be the slow labor of many years, arid can only be published very gradually. In the mean time I hope that this forerunner of the more special reports may serve to show that our year in Brazil, full as it was of enjoyment for all the party, was also rich in permanent results for science.

We have had service from Bishop Potter this morning, and since then we have been on deck reading, walking, watching a singular cloud, which the captain says is a cloud of smoke, in the direction of Pe- tersburg. We think it may be the smoke of a great deci- i 2 A JOURNEY IN BRAZIL. sive engagement going on while we sail peacefully along. What it means, or how the battle ends, if battle it be, we shall not know for two months perhaps.* Mr. Agassiz is busy to-day in taking notes, at regular intervals, of the temperature of the water, as we approach the Gulf Stream. To-night we cut it at right angles, and he will remain on deck to continue his observations. April od. — The Professor sat up last night as he in- tended, and found his watch, which was shared by one or two of his young assistants, very interesting. We crossed the Gulf Stream opposite Cape Hatteras, at a latitude where it is comparatively narrow, some sixty miles only in breadth. Entering it at about six o'clock, we passed out of it a little after midnight. The western boundary of the warm waters stretching along the coast had a temperature of about 57°. Immediately after entering it, the temperature began to rise gradually, the maximum being about 74°, falling occasionally, however, when we passed through a cold streak, to 68°. These cold streaks in the Gulf Stream, which reach to a considerable depth, the warm and cold waters descending together in immediate contact for at least a hundred fathoms, are attributed by Dr. Bache to the fact that the Gulf Stream is not stationary. It sways as a whole sometimes a little toward the shore, sometimes a little away from it, and, in consequence of this, the colder water from the coast creeps in, forming these verti- cal layers in its midst. The eastern boundary is warmer * On the 17th of May, nearly a month after our arrival in Kio, this cloud was interpreted to us. It was, indeed, charged with the issues of life and death, for it was on this day and the following that the final assaults on Petersburg were made, and the cloud which marred an otherwise stainless sky, as we were passing along the shores of Virginia, was, no doubt, the mass of smoke gath- ered above the opposing lines of the two armies. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 3 than the western one, for the latter is chilled by the Arctic currents, which form a band of cold water all along the Atlantic shore. Their influence is felt nearly to the lati- tude of Florida. On coming out of the Gulf Stream the temperature of the water was 68°, and so it continued for an hour longer, after which Mr. Agassiz ceased his obser- vations. To-day some of the gulf-weed was gathered by a sailor, and we found it crowded with life. Hydroids, in numbers, had their home upon it ; the delicate branching plumtilaria and a pretty campanularia, very like some of our New England species ; beside these, bryozoa, tiny com- pound mollusks, crusted its stem, and barnacles were abun- dant upon it. These are all the wonders that the deep has yielded us to-day, though the pretty Portuguese men-of-war go floating by the vessel, out of reach thus far. Such are the events of our life : we eat and drink and sleep, read, study Portuguese, and write up our journals. April 4th. — It has occurred to Mr. Agassiz, as a means of preparing the young men who accompany him for the work before them, to give a course of lectures on ship- board. Some preparation of the kind is the more necessary, since much of the work must be done independently of him, as it will be impossible for so large a party to travel together ; and the instructions needed will be more easily given in a daily lecture to all, than in separate conversa- tions with each one singly. The idea finds general favor. The large saloon makes an excellent lecture-room ; a couple of leaves from the dining-table with a black oil-cloth stretched across them serve as a blackboard. The audi- ence consists, not only of our own company, but includes the few ladies who are on board, Mr. Bradbury, the captain of our steamer, Bishop Potter, some of the ship's officers. 4 A JOURNEY IN BRAZIL. and a few additional passengers, all of whom seem to think the lecture a pleasant break in the monotony of a sea voy- age. To-day the subject was naturally suggested by the sea- weeds of the Gulf Stream, so recently caught and so crowded with life, — "A lecture on the Gulf Stream in the Gulf Stream," as one of the listeners suggests. It was opened, however, by a few words on the exceptional character of the position of this scientific commission on board the Colorado. " Fifty years ago, when naturalists carried their investiga- tions to distant lands, either government was obliged to pro- vide an expensive outfit for them, or, if they had no such patronage, scanty opportunities grudgingly given might be granted them on ordinary conveyances. Even if such ac- commodation were allowed them, their presence was looked upon as a nuisance : no general interest was felt in their objects ; it was much if they were permitted, on board some vessel, to have their bucket of specimens in a corner, which any sailor might kick over, unreproved, if it chanced to stand in his way. This ship, and the spirit prevailing in her com- mand, opens to me a vista such as I never dreamed of till I stood upon her deck. Here, in place of the meagre chances I remember in old times, the facilities could hardly be greater if the ship had been built as a scientific laboratory. If any such occasion has ever been known before, if any naturalist has ever been treated with such consideration, and found such intelligent appreciation of his highest aims, on board a merchant-ship fitted up for purposes of trade, I am not aware of it. I hope the first trip of the Colorado will be re- membered in the annals of science. I, at least, shall know whom to thank for an opportunity so unique. This voyage, and the circumstances connected with it, are, to me, the signs of a good time coming ; when men of different inter- VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 5 ests will help each other ; when naturalists will be more liberal and sailors more cultivated, and natural science and navigation will work hand in hand. And now for my lecture, — my first lecture on ship-board." The lecture was given, of course, specimen in hand, the various inhabitants of the branch of sea-weed giving their evidence in succession of their own structure and way of life. To these living illustrations were added drawings on the blackboard to show the transformations of the animals, their embryological history, &c.* Since the lecture, Captain Bradbury has fitted up a large tank as an aquarium, where any specimens taken during the voyage may be preserved and examined. Mr. Agassiz is perfectly happy, enjoying every hour of the voyage, as well he may, surrounded as he is with such considerate kindness. April Qth. — Though I took notes, as usual, of the lecture yesterday, I had not energy enough to enter them in my journal. The subject was the Gulf Stream, — the stream itself this time, not the animals it carries along with it. Mr. Agassiz's late observations, though deeply interesting to himself, inasmuch as personal confirmation of facts already known is always satisfactory, have nothing novel now-a- days ; yet the history of the facts connected with the dis- covery of the Gulf Stream, and their gradual development, is always attractive, and especially so to Americans, on ac- count of its direct connection with scientific investigations * The species of Hydroids most numerous upon the gulf-weed have not yet been described, and would form a valuable addition to the Natural History of the Acalcphs. For an account of the animals of this class inhabiting the Atlan- tic coast of North America, and especially the New England shores, I may ref«er to the third volume of my Contributions to the Natural History of the Uni^-d States, and to the second number of the Illustrated Catalogue of the Museum of Comparative Zoology at Cambridge. — L. A. 6 A JOURNEY IN BRAZIL. carried on under our government. Mr. Agassiz gave a slight sketch of this in opening his lecture. " It was Franklin who first systematically observed these facts, though they had been noticed long before by navigators. He recorded the temperature of the water as he left the American con- tinent for Europe, and found that it continued cold for a certain distance, then rose suddenly, and after a given time sank again to a lower temperature, though not so low as before. With the comprehensive grasp of mind charac- teristic of all his scientific results, he went at once beyond his facts. He inferred that the warm current, keeping its way so steadily through the broad Atlantic, and carrying tropical productions to the northern shores of Europe, must take its rise in tropical regions, must be heated by a tropical sun.* This was his inference : to work it out, to ascertain the origin and course of the Gulf Stream, has been, in a great degree, the task of the United States Coast Survey, under the direction of his descendant, Dr. Bache." f * " This stream," he writes, " is probably generated by the great accumu- t.ation of water on the eastern coast of America, between the tropics, by the trade-winds which constantly blow there." These views, though vaguely hinted at by old Spanish navigators, were first distinctly set forth by Frank- lin, and, as is stated in a recent printed report of the Coast Survey Explo- rations, " they receive confirmation from every discovery which the advance of scientific research brings to aid in the solution of the great problem of oceanic circulation." t No one can read the account of the explorations undertaken by the Coast Survey in the Gulf Stream, and continued during a number of successive years, and the instructions received by the officers thus employed from the Superintendent, Dr. A. D. Bache, without feeling how comprehensive, keen, and persevering was the intellect which has long presided over this department of our public works. The result is a very thorough survey of the stream, es- pecially along the coast of our own continent, with sections giving the temper- ature to a great depth, the relations of the cold and warm streaks, the form of the ocean bottom, as well as various other details respecting the direction and VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 7 * We are now fairly in the tropics. "The trades'1 blow heavily, and yesterday was a dreary day for those unused to the ocean ; the beautiful blue water, of a peculiar metallic tint, as remarkable in color, it seemed to me, as the water of the Lake of Geneva, did not console us for the heavy moral and physical depression of sea-sick mortals. To-day the world looks brighter ; there is a good deal of motion, but we are more accustomed to it. This morning the lec- ture had, for the first time, a direct bearing upon the work of the expedition. The subject was, " How to observe, and what are the objects of scientific explorations in mod- ern times." " My companions and myself have come together so sud- denly and so unexpectedly on our present errand, that we have had little time to organize our work. The laying out of a general scheme of operations is, therefore, the first and one of the most important points to be discussed between us. The time for great discoveries is passed. No student of nature goes out now expecting to find a new world, or looks in the heavens for any new theory of the solar system. The work of the naturalist, in our day, is to explore worlds the existence of which is already known ; to investigate, not to discover. The first explorers, in this modern sense, were Humboldt in the physical world, Cuvier in natural history, Lavoisier in chemistry, La Place in astronomy. They have been the pioneers in the kind of scientific work characteristic of our century. We who have chosen Brazil as our field must seek to make ourselves familiar with its physical features, its mountains and its rivers, its animals and plants. There is a change, however, to be introduced force of the current, the density and color of the water, and the animal and vegetable productions contained in it. (See Appendix No. I.) — L. A. 8 A JOURNEY IN BRAZIL. in our mode of work, as compared with that of former investigators. When less was known of animals and plants the discovery of new species was the great object. This has been carried too far, and is now almost the lowest kind of scientific work. The discovery of a new species as such does not change a feature in the science of natural history, any more than the discovery of a new asteroid changes the character of the problems to be investigated by astrono- mers. It is merely adding to the enumeration of objects. We should look rather for the fundamental relations among animals ; the number of species we may find is of impor- tance only so far as they explain the distribution and lim- itation of different genera and families, their relations to each other and to the physical conditions under which they live. Out of such investigations there looms up a deeper question for scientific men, the solution of which is to be the most important result of their work in coming genera- tions. The origin of life is the great question of the day. How did the organic world come to be as it is ? It must be our aim to throw some light on this subject by our pres- ent journey. How did Brazil come to be inhabited by the animals and plants now living there ? Who were its inhab- itants in past times ? What reason is there to believe that the present condition of things in this country is in any sense derived from the past ? The first step in this investi- gation must be to ascertain the geographical distribution of the present animals and plants. Suppose we first ex- amine the Rio San Francisco. The basin of this river is entirely isolated. Are its inhabitants, like its waters, com- pletely distinct from those of other basins ? Are its species peculiar to itself, and not repeated in any other river of the continent? Extraordinary as this result would seem, VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 9 I nevertheless expect to find it so. The next water-basin we shall have to examine will be that of the Amazons, which connects through the Rio Negro with the Orinoco. It lias been frequently repeated that the same species of fish exist in the waters of the San Francisco and in those of Guiana and of the Amazons. At all events, our works on fishes constantly indicate Brazil and Guiana as the common home of many species ; but this observation has never been made with sufficient accuracy to merit confi- dence. Fifty years ago the exact locality from which any animal came seemed an unimportant fact in its sci- entific history, for the bearing of this question on that of origin was not then perceived. To say that any speci- men came from South America was quite enough ; to specify that it came from Brazil, from the Amazons, the San Francisco, or the La Plata, seemed a marvellous accu- racy in the observers. In the museum at Paris, for instance, there are many specimens entered as coming from New York or from Par£ ; but all that is absolutely known about them is that they were shipped from those sea-ports. Nobody knows exactly where they were collected. So there are specimens entered as ooming from the Rio San Francisco, but it is by no means sure that they came exclusively from that water-basin. All this kind of investigation is far too loose for our present object. Our work must be done with much more precision ; it must tell something positive of the geographical distribution of animals in Brazil. There- fore, my young friends who come with me on this expedi- tion, let us be careful that every specimen has a label, recording locality and date, so secured that it shall reach Cambridge safely. It would be still better to attach two labels to each specimen, so that, if any mischance happens 10 A JOURNEY IN BRAZIL. to one, our record may not be lost. We must try not to mix the fishes of different rivers, even though they flow into each other, but to keep our collections perfectly dis- tinct. You will easily see the vast importance of thus ascertaining the limitation of species, and the bearing of the result on the great question of origin. " Something is already known. It is ascertained that the South American rivers possess some fishes peculiar to them. Were these fishes then created in these separate water-systems as they now exist, or have they been trans- ferred thither from some other water-bed ? If not born there, how did they come there ? Is there, or has there ever been, any possible connection between these water-sys- tems ? Are their characteristic species repeated elsewhere ? Thus we narrow the boundaries of the investigation, and bring it, by successive approaches, nearer the ultimate question. But the first inquiry is, How far are species distinct all over the world, and what are their limits ? Till this is ascertained, all theories about their origin, their derivation from one another, their successive transforma- tion, their migration from given centres, and so on, are mere beating about the bush. I allude especially to the fresh-water fishes, in connection with this investigation, on account of the precision of their boundaries. Looking at the matter theoretically, without a positive investigation, I do not expect to find a single species of the Lower Amazons above Tabatinga.* I base this supposition upon my own ob- * This anticipation was more than confirmed by the result of the journey. It is true that Mr. Agassiz did not go beyond the Peruvian frontier, and therefore could not verify his prophecy in that region. But he found the localization of species in the Amazons circumscribed within much narrower limits than he ex- pected, the whole length of the great stream, as well as its tributaries, being broken up into numerous distinct faunae. There can be no doubt that what is VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 11 servations respecting the distribution of species in the Euro- pean rivers. I have found that, while some species occur simultaneously in the many upper water-courses which com- bine to form the Rhine, the Rhone, and the Danube, most of them are not found in the lower course of these rivers ; that, again, certain species are found in two of these water- basins and do not occur in the third, or inhabit only one and are not to be met in the two others. The brook trout, for instance (^Salmo Fario), is common to the upper course and the higher tributaries of all the three river-systems, but does not inhabit the main bed of their lower course. So it is, also, and in a more striking degree, with the Salm- ling (Salmo Salvelinus). The Huchen (jSalmo Hucho) is only found in the Danube. But the distribution of the perch family in these rivers is, perhaps, the most remark- able. The Zingel (Aspro Zingel) and the Schraetzer (Aceri- na tSchrcetzer) are only found in the Danube ; while Acerina cernua is found in the Danube as well as in the Rhine, but not in the Rhone ; and Aspro asper in the Danube as well as in the Rhone, but not in the Rhine. The Sander (Lucioperca Sandra) is found in the Danube and the other large rivers of Eastern Europe, but occurs neither in the Rhine nor in the Rhone. The common perch (Perca flu- viatilis), on the contrary, is found both in the Rhine and Rhone, but not in the Danube, which, however, nourishes another species of true Perca, already described by Schaeffer as Perca vulgaris. Again, the pickerel (Esox Lucius) is common to all these rivers, especially in their lower course, and so is also the cusk (Lota vulgaris). The special dis- truc for nearly three thousand miles of its course is true also for the head-waters of the Amazons ; indeed, other investigators have already described some spe- cies from its higher tributaries differing entirely from those collected upon this expedition. 12 A JOURNEY IN BRAZIL. tribution of the carp family would afford many other striking examples, but they are too numerous and too little known to be used as an illustration here. " This is among the most remarkable instances of what I would call the arbitrary character of geographical dis- tribution. Such facts cannot be explained by any theory of accidental dispersion, for the upper mountain rivulets, in which these great rivers take their rise, have no con- nection with each other ; nor can any local circumstance explain the presence of some species in all the three basins, while others appear only in one, or perhaps in two, and are absent from the third, or the fact that certain species inhabiting the head-waters of these streams are never found in their lower course when the descent would seem so natural and so easy. In the absence of any positive ex- planation, we are left to assume that the distribution of ani- mal life has primary laws as definite and precise as those which govern anything else in the system of the universe. "It is for the sake of investigations of this kind that I wish our party to divide, in order that we may cover as wide a ground as possible, and compare a greater number of the water-basins of Brazil. I wish the same to be done, as far as may be, for all the classes of Vertebrates, as well as for Mollusks, Articulates, and Radiates. As we have no special botanist in the party, we must be content to make a methodical collection of the most characteristic families of trees, such as the palms and tree ferns. A col- lection of the stems of these trees would be especially important as a guide to the identification of fossil woods. Much more is known of the geographical distribution of plants than of animals, however, and there is, therefore, less to be done that is new in that direction. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 13 " Our next aim, and with the same object, namely, its bearing upon the question of origin, will be the study of the young, the collecting of eggs and embryos. This is the more important, since museums generally show only adult specimens. As far as I know, the Zoological Museum at Cambridge is the only one containing large collections of embryological specimens from all the classes of the ani- mal kingdom. One significant fact, however, is already known. In their earliest stages of growth all animals of the same class are much more alike than in their adult condition, and sometimes so nearly alike as hardly to be distinguished. Indeed, there is an early period when the resemblances greatly outweigh the differences. How far the representatives of different classes resemble one another remains to be ascertained with precision. There are two possible interpretations of these facts. One is that animals so nearly identical in the beginning must have been origi- nally derived from one germ, and are but modifications or transmutations, under various physical conditions, of this primitive unit. The other interpretation, founded on the same facts, is, that since, notwithstanding this material iden- tity in the beginning, no germ ever grows to be different from its parent, or diverges from the pattern imposed upon it at its birth, therefore some other cause besides a material one must control its development ; and if this be so, we have to seek an explanation of the differences between animals outside of physical influences. Thus far both these views rest chiefly upon personal convictions and opinions. The true solution of the problem must be sought in the study of the development of the animals themselves, and embry- ology is still in its infancy ; for, though a very complete study of the embryology of a few animals has been iniule, 14 A JOURNEY IN BRAZIL. yet these investigations include so small a number of repre- sentatives from the different classes of the animal kingdom that they do not yet give a basis for broad generalizations. Very little is known of the earlier stages in the formation of hosts of insects whose later metamorphoses, including the change of the already advanced larva, first to the con- dition of a chrysalis and then to that of a perfect insect, have been carefully traced. It remains to be ascertained to what extent the caterpillars of different kinds of butter- flies, for instance, resemble one another during the time of their formation in the egg. An immense field of observa- tion is open in this order alone. " I have, myself, examined over one hundred species of bird embryos, now put up in the museum of Cambridge, and found that, at a certain age, they all have bills, wings, legs, feet, &c., &c. exactly alike. The young robin and the young crow are web-footed, as well as the duck. It is only later that the fingers of the foot become distinct. How very interesting it will be to continue this investiga- tion among the tropical birds ! — to see whether, for instance, the toucan, with its gigantic bill, has, at a certain age, a bill like that of all other birds ; whether the spoonbill ibis has, at the same age, nothing characteristic in the shape of its bill. No living naturalist could now tell you one word about all this ; neither could he give you any infor- mation about corresponding facts in the growth of the fishes, reptiles, or quadrupeds of Brazil, not one of the young of these animals having ever been compared with the adult. In these lectures I only aim at showing you what an extensive and interesting field of investigation opens before us ; if we succeed in cultivating even a few corners of it we shall be fortunate." VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 15 In the evening, which is always the most enjoyable part of our day, we sat on the guards and watched the first tropi- cal sunset we had yet seen. The sun went down in purple and gold, and, after its departure, sent back a glow that crimsoned the clouds almost to the zenith, dying off to paler rose tints on the edges, while heavy masses of gray vapor, just beginning to be silvered by the moon, swept up from the south. April 1th. — To-day the lecture was upon the physical features of South America, something with reference to the geological and geographical work in which Mr. Agassiz hopes to have efficient aid from his younger assistants. So much of the lecture consisted of explanations given upon geological maps that it is difficult to record it. Its principal object, however, was to show in what direction they should work in order to give greater precision to the general information already secured respecting the forma- tion of the continent. " The basin of the Amazons, for instance, is a level plain. The whole of it is covered with loose materials. We must watch carefully the char- acter of these loose materials, and try to track them to their origin. As there are very characteristic rocks in various parts of this plain, we shall have a clew to the nature of at least some portion of these materials. My own previous studies have given me a special interest in certain questions connected with these facts. What power has ground up these loose materials ? Are they the result of disintegration of the rock by ordinary atmospheric agents, or are they caused by the action of water, or by that of glaciers ? Was there ever a time when large masses of ice descended far lower than the present snow line of the Andes, and, moving over the low lands, ground these 16 A JOURNEY IN BRAZIL. materials to powder ? We know that such an agency has been at work on the northern half of this hemisphere. We have now to look for its traces on the southern half, where no such investigations have ever been made within its warm latitudes ; though to Darwin science is already indebted for much valuable information concerning the glacial phenomena of the temperate and colder portions of the South American continent. We should examine the loose materials in every river we ascend, and see what relation they bear to the dry land above. The color of the water in connection with the nature of the banks will tell us something. The waters of the Rio Branco, for instance, are said to be milky white ; those of the Rio Negro, black. In the latter case the color is probably owing to the decomposition of vegetation. I would advise each one of our parties to pass a large amount of water from any river or stream along which they travel through a filter, and to examine the deposit microscopically. They will thus ascertain the character of the detritus, whether from sand, or lime, or granite, or mere river mud formed by the decomposition of organic matter. Even the smaller streams and rivulets will have their peculiar char- acter. The Brazilian table-land rises to a broad ridge running from west to east, and determining the direction of the rivers. It is usually represented as a mountain range, but is in fact nothing but a high flat ridge serving as a water-shed, and cut transversely by deep fissures in which the rivers flow. These fissures are broad in their lower parts, but little is known of their upper range ; and whoever will examine their banks carefully will do an important work for science. Indeed, very little is known accurately of the geology of Brazil. On the geological maps almost the whole country is represented as consisting of granite. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 17 If this be correct, it is very inconsistent with what we know of the geological structure of other continents, where the stratified rocks are in much larger proportions." Upon this followed some account of the different kinds of valley formation and of terraces. " Do the old terraces above the rivers of South America correspond to the river terraces on any of our rivers, — those of the Connecticut, for instance, — showing that their waters had formerly a much greater depth and covered a much wider bottom ? There must of course have been a cause for this great accumulation of water in ancient periods. I account for it in the northern half of the hemisphere by the melting of vast masses of ice in the glacial period, causing immense freshets. There is no trustworthy account of the river terraces in Brazil. Bates, however, describes flat-topped hills between Santarem and Para in the narrow part of the valley, near Almeyrim, rising 800 feet above the present level of the Amazons. If this part of the valley were flooded in old times, banks might have been formed of which these hills are a remnant. But because such a theory might account for the facts it does not follow that the theory is true. Our work must be to study the facts, to see, among other things, of what these hills are built, whether of rock or of loose materials. No one has told us anything as yet of their geological constitution." To-day we have seen numbers of flying-fish from the deck, and were astonished at the grace and beauty of their motion, which we had supposed to be rather a leap than actual flight. And flight indeed it is not, their pectoral * Mr. Agassiz afterward visited these hills himself, and an account of their structure and probable origin will be found in the chapter on the physical history of the Amazons. 2 18 A JOURNEY IN BRAZIL. fins acting as sails rather than wings, and carrying them along on the wind. They skim over the water in this way to a great distance. Captain Bradbury told us he had followed one with his glass and lost sight of it at a consider- able distance, without seeing it dip into the water again. Mr. Agassiz has great delight in watching them.* Having never before sailed in tropical seas, he enjoys every day some new pleasure. April 9th. — Yesterday Mr. Agassiz lectured upon the traces of glaciers as they exist in the northern hemisphere, and the signs of the same kind to be sought for in Brazil. After a sketch of what has been done in glacial investigation in Europe and the United States, showing the great extension of ice over these regions in ancient times, he continued as fol- lows : " When the polar half of both hemispheres was covered by such an ice shroud, the climate of the whole earth must have been different from what it is now. The limits of the ancient glaciers give us some estimate of this difference, though of course only an approximate one. A degree of temperature in the annual average of any given locality corresponds to a degree of latitude ; that is, a degree of temperature is lost for every degree of latitude as we travel northward, or gained for every degree of latitude as we travel southward. In our times, the line at which the average annual temperature is 32°, that is, at which glaciers may be formed, is in latitude 60° or thereabouts, the latitude of Greenland ; while the height at which they may originate in latitude 45° is about 6,000 feet. If it appear that the ancient southern limit of glaciers is in latitude 36°, we must admit that in those days the present climate of Greenland extended to that line. Such a change of climate with * See Appendix No. II. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 19 reference to latitude must have been attended by a corre- sponding change of climate with reference to altitude. Three degrees of temperature correspond to about one thousand feet of altitude. If, therefore, it is found that the ancient limit of glacier action descends on the Andes, for instance; to 7,000 feet above the level of the sea under the equator, the present line of perpetual snow being at 15,000, it is safe to infer that in those days the climate was some 24° or thereabouts below its present temperature. That is, the temperature of the present snow line then pre- vailed at a height of 7,000 feet above the sea level, as the present average temperature of Greenland then prevailed in latitude 36°. I am as confident that we shall find these indications at about the limit I have pointed out as if I had already seen them. I would even venture to prophesy that the first moraines in the valley of the Maranon should be found where it bends eastward above Jaen." Although the weather is fine, the motion of the ship continues to be so great that those of us who have not what are popularly called " sea-legs," have much ado to keep our balance. For my own part, I am beginning to feel a personal animosity to " the trades." I had imagined them to be soft, genial breezes wafting us gently southward ; instead of which they blow dead ahead all the time, and give us no rest night or day. And yet we are very unreasonable to grumble ; for never were greater comforts and conveniences * It proved in the sequel unnecessary to seek the glacial phenomena of tropical South America in its highest mountains. In Brazil the moraines are a? distinct and as well preserved in some of the coast ranges on the Atlantic side, not more than twelve or fifteen hundred feet high, as in any glaciated localities known to geologists in more northern parts of the world. The snow line, even in those latitudes, then descended so low that m:i--t •> of ice formed above its level actually forced their way down to the sea-coast. — L. A. 20 A JOURNEY IN BRAZIL. provided for voyagers on the great deep than are to be found on this magnificent ship. The state-rooms large and commodious, parlor and dining-hall well ventilated, cool, and cheerful, the decks long and broad enough to give a chance for extensive " constitutionals " to everybody who can stand upright for two minutes together, the attendance punctual and admirable in every respect ; in short, nothing is left to be desired except a little more stable footing. April ~LQth. — A rough sea to-day, notwithstanding which we had our lecture as usual, though I must say, that, owing to the lurching of the ship, the lecturer pitched about more than was consistent with the dignity of science. Mr. Agas- siz returned to the subject of embryology, urging upon his assistants the importance of collecting materials for this object as a means of obtaining an insight into the deeper relations between animals. " Heretofore classification has been arbitrary, inasmuch as it has rested mainly upon the interpretation given to structural differences by various observers, who did not measure the character and value of these differences by any natural standard. I believe that we have a more certain guide in these matters than opinion or the indi- vidual estimate of any observer, however keen his insight into structural differences. The true principle of classifica- tion exists in Nature herself, and we have only to decipher it. If this conviction be correct, the next question is, How can we make this principle a practical one in our laboratories, an active stimulus in our investigations ? Is it susceptible of positive demonstration in material facts ? Is there any method to be adopted as a correct guide, if we set aside the idea of originating systems of classification of our own, and seek only to read that already written in VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 21 nature ? I answer, Yes. The standard is to be found in the changes animals undergo from their first formation in the egg to their adult condition. " It would be impossible for me here and now to give you the details of this method of investigation, but I can tell you enough to illustrate my statement. Take a homely and very familiar example, that of the branch of Articulates. Naturalists divide this branch into three classes, — Insects, Crustacea, and Worms ; and most of them tell you that Worms are lowest, Crustacea next in rank, and that Insects stand highest, while others have placed the Crustacea at the head of the group. We may well ask why. Why does an insect stand above a crustacean, or, vice versa, why is a grass- hopper or a butterfly structurally superior to a lobster or a shrimp ? And indeed there must be a difference in opinion as to the respective standing of these groups so long as their classification is allowed to remain a purely arbitrary one, based only upon interpretation of anatomical details. One man thinks the structural features of Insects superior, and places them highest ; another thinks the structural features of the Crustacea highest, and places them at the head. In either case it is only a question of individual appreciation of the facts. But when we study the gradual development of the insect, and find that in its earliest stages it is worm-like, in its second, or chrysalis stage, it is crusta- cean-like, and only in its final completion it assumes the character of a perfect insect, we have a simple natural scale by which to estimate the comparative rank of these animals. Since we cannot suppose that there is a retrograde move- ment in the development of any animal, we must believe that the insect stands highest, and our classification in this instance is dictated by Nature herself. This is one of the A JOURNEY IN BRAZIL. most striking examples, but there are others quite as much so, though not as familiar. The frog, for instance, in its successive stages of development, illustrates the comparative standing of the orders composing the class to which it belongs. These orders are differently classified by various naturalists, according to their individual estimate of their structural features. But the growth of the frog, like that of the insects, gives us the true grade of the type.* There are not many groups in which this comparison has been carried out so fully as in the insects and frogs ; but where- ever it has been tried it is found to be a perfectly sure test. Occasional glimpses of these facts, seen disconnectedly, have done much to confirm the development theory, so greatly in vogue at present, though under a somewhat new form. Those who sustain these views have seen that there was a gradation between animals, and have inferred that it was a material connection. But when we follow it in the growth of the animals themselves, and find that, close as it is, no animal ever misses its true development, or grows to be anything but what it was meant to be, we are forced to * In copying the journal from which these notes are taken, I have hesitated to burden the narrative with anatomical details. But for those who take an interest in such investigations it may be well to add here that the frog, when first hatched, is simply an oblong body, without any appendages, and tapering slightly towards its posterior end. In that condition it resembles the Cecilia. In its next stage, that of the tadpole, when the extremity has elongated into a tail, the gills are fairly developed, and it has one pair of imperfect legs, it resembles the Siren, with its rudimentary limbs. In its succeeding stages, when the same animal has two pairs of legs and a fin around the tail, it recalls the Proteus and Menobranchus. Finally the gills are suppressed, the animal breathes through lungs, but the tail still remains ; it then recalls Menopoma and the Salamanders. At last the tail shrinks and disappears, and the frog is complete. This gives us a standard by which the relative position of the leading groups of the class may safely be deter- mined. — L. A. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 23 admit that the gradation which unquestionably unites all animals is an intellectual, not a material one. It exists in the Mind which made them. As the works of a human intellect are bound together by mental kinship, so arc the thoughts of the Creator spiritually united. I think that considerations like these should be an inducement for us all to collect the young of as many animals as possible on this journey. In so doing we may change the fundamental principles of classification, and confer a lasting benefit on science. " It is very important to select the right animals for such investigations. I can conceive that a lifetime should be passed in embryological studies, and yet little be learned of the principles of classification. The embryology of the worm, for instance, would not give us the natural classifica- tion of the Articulates, because we should see only the first step of the series ; we should not reach the sequence of the development. It would be like reading over and over again the first chapter of a story. The embryology of the Insects, on the contrary, would give us the whole succession of a scale on the lowest level of which the Worms remain forever. So the embryology of the frog will give us the classification of the group to which it belongs, but the embryology of the Cecilia, the lowest order in the group, will give us only the initiatory steps. In the same way the naturalist who, in studying the embryology of the reptiles, should begin with their lowest representatives, the serpents, would make a great mistake. But take the alligator, so abundant in the regions to which we are going. An alligator's egg in the earliest condition of growth has never been opened by u naturalist. The young have been occasionally taken from the egg just before hatching, but absolutely nothing is known 24 A JOURNEY IN BRAZIL. of their first phases of development. A complete embryology of the alligator would give us not only the natural classifica- tion of reptiles as they exist now, but might teach us some- thing of their history from the time of their introduction upon earth to the present day. For embryology shows us not only the relations of existing animals to each other, but their relations to extinct types also. One prominent result of embryological studies has been to show that animals in the earlier stages of their growth resemble ancient represent- atives of the same type belonging to past geological ages The first reptiles were introduced in the carboniferous epoch, and they were very different from those now existing. They were not numerous at that period ; but later in the world's history there was a time, justly called the ' age of reptiles,' when the gigantic Saurians, Plesiosaurians, and Ichthyosaurians abounded. I believe, and my conviction is drawn from my previous embryological studies, that the changes of the alligator in the egg will give us the clew to the structural relations of the Reptiles from their first crea- tion to the present day, — will give us, in other words, their sequence in time as well as their sequence in growth. In the class of Reptiles, then, the most instructive group we can select with reference to the structural relations of the type as it now exists, and their history in past times, will be the alligator. We must therefore neglect no opportunity of collecting their eggs in as large numbers as possible. " There are other animals in Brazil, low in their class to be sure, but yet very important to study ernbryologically, on account of their relation to extinct types. These are the sloths and armadillos, — animals of insignificant size in our days, but anciently represented in gigantic proportions. The Megatherium, the Mylodon, the Megalonyx, were some VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 25 of these immense Mammalia. I believe that the embryonic changes of the sloths and armadillos will explain the struc- tural relations of those huge Edentata and their connection with the present ones. South America teems with the fossil bones of these animals, which indeed penetrated into the northern half of the hemisphere as high up as Georgia and Kentucky, where their remains have been found. The living representatives of the family are also numerous in South America, and we should make it one of our chief objects to get specimens of all ages and examine thorn from their earliest phases upward. We must, above all, try not to be led away from the more important aims of our study by the diversity of objects. I have known many young natu- ralists to miss the highest success by trying to cover too much ground, — by becoming collectors rather than investi- gators. Bitten by the mania for amassing a great number and variety of species, such a man never returns to the general consideration of more comprehensive features. We must try to set before ourselves certain important questions, and give ourselves resolutely to the investigation of these points, even though we should sacrifice less important things more readily reached. " Another type full of interest, from an embryological point of view, will be the Monkeys. Since some of our scien- tific colleagues look upon them as our ancestors, it is impor- tant that we should collect as many facts as possible concern- ing their growth. Of course it would be better if we could make the investigation in the land of the Orangs, Gorillas, and Chimpanzees, — the highest monkeys and the nearest to man in their development. Still even the process of growth in the South American monkey will be very instructive. Give a mathematician the initial elements of a series, and 26 A JOURNEY IN BRAZIL. he will work out the whole ; and so I believe when the laws of embryological development are better understood, natu- ralists will have a key to the limits of these cycles of growth, and be able to appoint them their natural boundaries even from partial data. " Next in importance I would place the Tapirs. This is one of a family whose geological antecedents are very important and interesting. The Mastodons, the Palaeothe- rium, the Dinotherium, and other large Mammalia of the Tertiaries, are closely related to the Tapir. The elephant, rhinoceros, and the like, are of the same family. From its structural standing next to the elephant, which is placed highest in the group, the embryology of the Tapir would give us a very complete series of changes. It would seem from some of the fossil remains of this family that the Pachyderms were formerly more nearly related to the Ruminants and Rodents than they now are. Therefore it would be well to study the embryology of the Capivari, the Paca, and the Peccary, in connection with that of the Tapir. Lastly, it will be important to learn something of the em- bryology of the Manatee or Sea-Cow of the Amazons. It is something -like a porpoise in outline, and seems to be the modern representative of the ancient Dinotherium." April Vlth. — The lecture to-day was addressed especially to the ornithologists of the party, its object being to show how the same method of study, — that of testing the classifi- cation by the phases of growth in the different groups, — might be applied to the birds as profitably as to other types. We have made good progress in the last forty-eight hours, and are fast leaving our friends " the trades " behind. The captain promises us smooth waters in a day or two. With the dying away of the wind will come greater heat, but as VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 27 yet we have had no intensely warm weather. The sun, however, keeps us within doors a great part of the day, but in the evening we sit on the guards, watch the sunset over the waters, and then the moonlight, and so while away the time till nine or ten o'clock, when one by one the party disperses. The sea has been so rough that we have not been able to capture anything, but when we get into smoother waters, our naturalists will be on the look out for jelly-fish, argonautas, and the like. April \Wi. — In to-day's lecture Mr. Agassiz returned again to the subject of geographical distribution and the importance of localizing the collections with great precision. " As Rio de Janeiro is our starting-point, the water-system in its immediate neighborhood will be as it were a school- room for us during the first week of our Brazilian life. We shall not find it so easy a matter as it seems to keep our collections distinct in this region. The head-waters of some of the rivers near Rio, flowing in opposite directions, are in such close proximity that it will be difficult sometimes to distinguish them. Outside of the coast range, to which the Organ Mountains belong, are a number of short streams, little rills, so to speak, emptying directly into the ocean. It will be important to ascertain whether the same animals occur in all these short water-courses. I think this will be found to be the case, because it is so with corresponding small rivers on our northern coast. There are little rivers along the whole coast from Maine to New Jersey ; all these dis- connected rivers contain a similar fauna. There is another extensive range inland of the coast ridge, the Serra de Mantiquera, sloping gently down to the ocean south of the Rio Belmonte or Jequitinhonha. Rivers arising in this range are more complex ; they have J(arge tributaries, 28 A JOURNEY IN BRAZIL. Their upper part is usually broken by waterfalls, their lower course being more level ; probably in the lower courses of these rivers we shall find fishes similar to those of the short coast streams, while in the higher broken waters we shall find distinct faunas." The lecture closed with some account of the excursions likely to be undertaken in the neighborhood of Rio de Janeiro on arriving, and with some practical instructions about collecting, based upon Mr. Agassiz's personal experience.* * On account of the many exploring expeditions for which the Bay of Eio de Janeiro has been a favorite port, it has acquired a special interest for the naturalist. It may seem at first sight as if the fact that French, English, German, Russian, and American expeditions have followed each other in this locality, during the last century, each bringing away its rich harvest of speci- mens, by diminishing its novelty would rather lessen than increase its interest as a collecting ground. On the contrary, for the very reason that the speci- mens from which the greater part of the descriptions and figures contained in the published accounts of these voyages were obtained from Rio de Janeiro and its neighborhood, it becomes indispensable that every zoological museum aiming at scientific accuracy and completeness should have original specimens from that very locality for the identification of species already described. Otherwise doubts respecting the strict identity or specific difference of speci- t mens obtained on other parts of the Atlantic shore, not only in South America but in Central and North America, may at any time invalidate important gen- eralizations concerning the distribution of animals in these seas. From this point of view, the Bay of Rio de Janeiro forms a most important centre of comparison, and it was for this reason that we made so prolonged a stay there. Although the prospect of discovering any novelties was diminished by the extensive investigations of our predecessors, I well knew that whatever we collected there would greatly increase the value of our collections elsewhere. One of my special aims was to ascertain how far the marine animals inhabiting the coast of Brazil to the south of Cape Frio differed from those to the north of it, and furthermore, how the animals found along the coast between Cape Frio and Cape St. Roque differed from or agreed with those inhabiting the more northern shore of the continent and the West Indian Islands. In the course of the following chapters I shall have occasion to return, more in de- tail, to this subject. — L. A. VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 29 April llth. — Last evening was the most beautiful we have had since we left home ; perfectly clear with the exception of soft white masses of cloud on the horizon, all their edges silvered by the moonlight. We looked our last for many months to come on the north star, and saw the southern cross for the first time. With the visible image I lost a far more wonderful constellation which had lived in my imagination ; it has vanished with all its golden glory, a celestial vision as amazing as that which converted Constan- tine, and in its place stands the veritable constellation with its four little points of light. The lecture to-day was upon the fishes of South America. " I will give you this morning a slight sketch of the charac- teristic fishes in South America, as compared with those of the Old World and North America. Though I do not know how the fishes are distributed in the regions to which we are going, and it is just upon the investigation of this point that I want your help, I know their character as dis- tinguished from those of other continents. We must re- member that the most important aim of all our studies in this direction will be the solution of the question whether any given fauna is distinct and has originated where it now exists. To this end I shall make you acquainted with the Brazilian animals so far as I can in the short time we have before beginning our active operations, in order that you may be prepared to detect the law of their geographical distribution. I shall speak to-day more especially of the fresh-water fishes. " In the northern hemisphere there is a remarkable group of fishes known as the Sturgeons. They are chiefly found in the waters flowing into the Polar seas, as the Mackenzie River on our own continent, the Lena and Yenissoi in ilu- 30 A JOURNEY IN BRAZIL. Old World, and in all the rivers and lakes of the temperate zone, communicating with the Atlantic Ocean. They occur in smaller numbers in most tributaries of the Mediterra- nean, but are common in the Volga and Danube, as well as in the Mississippi, in some of the rivers on our north- ern Atlantic and Pacific coasts, and in China. This fam- ily has no representatives in Africa, Southern Asia, Austra- lia, or South America, but there is a group corresponding in a certain way to it in South America, — that of the Go- niodonts. Though some ichthyologists place them widely apart in their classifications, there is, on the whole, a striking resemblance between the Sturgeons and Gonio- donts. Groups of this kind, reproducing certain features common to both, but differing by special structural modifica- tions, are called ' representative types.' This name applies more especially to such groups when they are distributed over different parts of the world. To naturalists the com- parison of one of these types with another is very interest- ing, as touching upon the question of origin of species. To those who believe that animals are derived from one another the alternative here presented is very clear : either one of these groups grew out of the other, or else they both had common ancestors which were neither Sturgeons nor Goni- odonts, but combined the features of both and gave birtty to each. " There is a third family of fishes, the Hornpouts or Bull- heads, called Siluroids by naturalists, which seem by their structural character to occupy an intermediate position be- tween the Sturgeons and Goniodonts. There would seem to be, then, in these three groups, so similar in certain fea- tures, so distinct in others, the elements of a series. But while their structural relations suggest a common origin, VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 31 their geographical distribution seems to exclude it. Take, for instance, the Hornpouts ; they are very few in the north- ern hemisphere, hardly ever occurring in those rivers where the Sturgeons abound, and they are very numerous in the southern hemisphere, in southern Asia, Australia, Africa, and South America, where the Sturgeons are altogether wanting. In South America the Siluroids everywhere exist with the Goniodonts, in all other parts of the world without them ; the Goniodonts being only found in South America. If these were the ancestors of the Siluroids in South Amer- ica, they were certainly not their ancestors anywhere else. If the Sturgeons were the ancestors of the Siluroids and of the Goniodonts, it is strange that their progeny should con- sist of these two families in South America, and in the Old World of the Siluroids only. But if all three had some other common ancestry, it would be still more extraordinary that its progeny should exhibit so specific a distribution upon the surface of our globe. The Siluroids lay very large eggs, and as they are very abundant in South America we shall no doubt have opportunities of collecting them. Of the re- production of the Goniodonts absolutely nothing is known. Of course the embryology of both these groups would have a direct bearing on the problem of their origin. "Another family very abundant in various parts of the world is that of the Perches. They are found all over North America, Europe, and Northern Asia ; but there is not one to be found in the fresh waters of the southern hemisphere. In South America and in Africa they are represented how- ever by a very similar group, that of the Chromids. These two groups are so much akin that from their structure it would seem natural to suppose that the Chromids were transformed Perches ; the more so, since in the western 82 A JOURNEY IN BRAZIL. hemisphere the latter extend from the high north to Texas, south of which they are represented by the Chromids. Here the geographical as well as the structural transition would seem an easy one. But look at the eastern hemisphere. Perches abound in Asia, Europe, and Australia, but there are no Chromids there. How is it that the Perches of this continent have been so fertile in producing Chromids, and the Perches of all other continents, except Africa, absolutely sterile in this respect ? Or if we reverse the proposition, and suppose the Perches to have grown out of the Chromids, why have their ancestry disappeared so completely on the Asiatic side of the world, while they do not seem to have diminished on this ? And if Perches and Chromids should be represented as descending from an older common type, I would answer that Palaeontology knows nothing of such a pedigree. " Next come the Chubs, or in scientific nomenclature the Cyprinoids. These fishes, variously called Chubs, Suckers, or Carps, abound in all the fresh waters of the northern hemisphere. They are also numerous in the eastern part of the southern hemisphere, but have not a single represent- ative in South America. As the Goniodonts are charac- teristic of the southern hemisphere in its western half, so this group seems to be characteristic of it in its eastern half. But while the Cyprinoids have no representative in South America, there is another group there, structurally akin to them, called the Cyprinodonts. They are all smalL sized ; our Minnows belong to this group. From Maine to Texas they are found in all the short rivers or creeks all along the coast. It is for this reason that I expect to find the short coast rivers of South America abounding in Min nows. I remember to have found in the neighborhood of VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 33 Mobile no less than six new species in the course of an af- ternoon's ramble. These fishes are almost all viviparous, or at least lay their eggs in a very advanced state of develop- ment of the young. The sexes differ so greatly in appear- ance that they have sometimes been described as distinct species, nay, even as distinct genera.* We must be on our guard against a similar mistake. Here again we have two groups, the Cyprinoids and Cyprinodonts, so similar in their structural features that the development of one out of the other naturally suggests itself. But in South Amer- ica there are no Cyprinoids at all, while the Cyprinodonts abound ; in Europe, Asia, and North America on the con- trary, the Cyprinoids are very numerous and the Cyprino donts comparatively few." The Characines were next con- sidered with reference to their affinities as well as their geographical distribution ; and a few remarks were added upon the smaller families known to have representatives in the fresh waters of South America, such as the Erythri- noids, the Gymnotines, t 44 A JOURNEY IN BRAZIL. the looseness in the methods of study upon which it is based. Whatever be your ultimate opinions on this subject, let them rest on facts and not on arguments, however plausible. This is not a question to be argued, it is one to be investigated. " As I have advanced in these talks with you, I have become more and more dissatisfied, feeling the difficulty of laying out our work without a practical familiarity witli the objects themselves. But this is the inevitable position of one who is seeking the truth : till we have found it, we are more or less feeling our way. I am aware that in my lectures I have covered a far wider range of subjects than we can handle, even if every man do his very best ; if we accomplish one tenth of the work I have suggested, I shall be more than satisfied with the result of the expedition. In closing, I can hardly add anything to the impressive admonitions of Bishop Potter in his parting words to us last Sunday, for which I thank him in your name and my own. But I would remind you, that, while America has recovered her political inde- pendence, while we all have that confidence in our insti- tutions which makes us secure, that so far as we are true to them, doing what we do conscientiously and in full view of our responsibilities we shall be in the right path, we have not yet achieved our intellectual indepen- dence. There is a disposition in this country to refer all literary and scientific matters to European tribunals ; to accept a man because he has obtained the award of societies abroad. An American author is often better satisfied if he publish his book in England than at home. In my opinion, every man who publishes his work on the other side of the water deprives his country of so much VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 45 intellectual capital to which she has a right. Publish your results at home, and let Europe discover whether they are worth reading. Not until you are faithful to your citizenship in your intellectual as well as your po- litical life, will you be truly upright and worthy students of nature." At the conclusion of these remarks a set of resolutions was read by Bishop Potter.* They were followed by a few little friendly speeches, all made in the most informal and cordial spirit ; and so ended our course of lectures on board the Colorado. Later in the day we observed singular bright red patches in the sea. Some were not less than seven or eight feet in length, rather oblong, and the whole mass looked as red as blood. Sometimes they seemed to lie on the very top of the water, sometimes to be a little below it, so as only to tinge the rippling surface. One of the sailors succeeded in catching a portion of it in a bucket, when it was found to consist of a solid mass of little crustaceans, bright red in color. They were all very lively, keeping up a constant rapid motion. Mr. Agassiz examined them under the microscope and found them to be the young of a crab. He has no doubt that every such patch is a single brood, floating thus compactly together like spawn. * See Appendix No. III. 46 A JOURNEY IN BRAZIL. CHAPTER II.

April 23e?. — Yesterday at early dawn we made Cape Frio light, and at seven o'clock were aroused by the wel- come information that the Organ Mountains were in sight. The coast range here, though not very lofty, (its highest summits ranging only from two to three thousand feet,) is bold and precipitous. The peaks are very conical, and the sides slope steeply to the water's edge, where, in many places, a wide beach runs along their base. The scenery grew more picturesque as we approached the entrance of the bay, which is guarded by heights rising sentinel-like on either side. Once within this narrow rocky portal, the immense harbor, stretching northward for more than twenty miles, seems rather like a vast lake enclosed by mountains than like a bay. On one side extends the ridge which shuts it from the sea, broken by the sharp peaks of the Corcovado, the Tijuca, and the flat-topped Gavia ; on the other side, and more inland, the Organ BIO DE JANEIRO AND ITS ENVIRONS. 47 Mountains lift their singular needle-like points, while within the entrance rises the bare bleak rock so well known as the Sugar Loaf (Pao de Assucar^). Were it not for the gateway behind us, through which we still have a glimpse of the open ocean, and for the shipping lying here at anchor, leaving the port or entering it, we might easily believe that we were floating on some great quiet sheet of inland water. We reached our anchorage at eleven o'clock, but were in no haste to leave the ocean home where we have been so happy and so comfortable for three weeks past ; and as the captain had kindly invited us to stay on board till our permanent arrangements were made, we remained on deck, greatly entertained by all the stir and confusion attending our arrival. Some of our young people took one of the many boats which crowded at once around our steamer, and went directly to the city ; but we were satisfied with the impressions of the day, and not sorry to leave them undisturbed. As night came on, sunset lit up the mountains and the harbor. In this latitude, however, the glory of the twilight is soon over, and as darkness fell upon the city it began to glitter with innu- merable lights along the shore and on the hillsides. The city of Rio de Janeiro spreads in a kind of crescent shape around the western side of the bay, its environs stretching out to a considerable distance along the beaches, and running up on to the hills behind also. On account of this disposition of the houses, covering a wide area and scattered upon the water's edge, instead of being compact and concentrated, the appearance of the city at night is exceedingly pretty. It has a kind of scenic effect. The lights run up on the hill-slopes, a little cluster crown- 48 A JOURNEY IN BRAZIL. ing their summits here and there, and they glimmer all along the shore for two or three miles on either side of the central, business part of the town. Soon after our arrival Mr. Agassiz received an official visit from a custom-house agent, saying that he had orders to land all our baggage without examination, and that a boat would be sent at any day and hour convenient to him to bring his effects on shore. This was a great relief, as the scientific apparatus, added to the personal luggage of so large a party, makes a fearful array of boxes, cases, ^*. ii f k— I'-f/iV «*>v yg5 .^ '^ - -v ^ • II" «^ 'I- %;^ * Ufe: j ' >*v- =r-:=T ^3^?^i;,T,- ^^ .mEV* i i • Wi*' « iffl / ' - ^" * VT" *" - jy /jp '/it.' . • j./^. ./ •<--'. /* . • JA y*-*" ' .

On the embankments also between which we passed, vines of many varieties were creeping down, as if they would fain clothe in green garments the ugly gaps the railroad had made. Yet it must be confessed that, in this instance, the railroad has not destroyed, but rather heightened, the picturesque scen- ery, cutting, as it does, through passes which give beauti- ful vistas into the heart of the mountain range. Once, as we issued from a tunnel, where the darkness seemed tan- gible, upon an exquisite landscape all gleaming in the sunshine, a general shout from the whole party testified their astonishment and admiration. "We. were riding on an open car in front* of the engine, so that nothing im- peded our view, and we had no inconvenience from smoke or cinders. During the latter part of the ride we came into the region of the most valuable coffee-plantations ; and indeed the road is chiefly supported by the transpor- • tation of the immense quantities of coffee raised along its track or beyond it. Near its terminus is an extensive fazenda, from which we were told that five or six hun- dred tons of coffee are sent out in a good year. These fazendas are singular-looking establishments, low (usually only one story) and very spreading, the largest of them covering quite an extensive area. As they are rather isolated in situation, they must include within their own borders all that is needed to keep them up. There is something very primitive in the way of life of these great country proprietors. Major Ellison told me that some *time ago a wealthy Marqueza living at some dis- tance beyond him in the interior, and going to town for a stay of a few weeks, stopped at his house to rest. 5G A JOURNEY IN BRAZIL. She had a troop of thirty-one pack-mules, laden with all conceivable baggage, besides provisions of every sort, fowls, harns, &c., and a train of twenty-five servants. Their hos- pitality is said to be unbounded ; you have only to present yourself at their gates at the end of a day's journey, and if you have the air of a respectable traveller, you are sure of a hearty welcome, shelter and food. The card of a friend or a note of introduction insures you all the house can afford for as long as you like to stay. The last three miles of our journey was over what is called the " temporary road," the use of which will be discontinued as soon as the great tunnel is completed. I must say, that to the inexperienced this road looks ex- ceedingly perilous, especially that., part of it which is carried over a wooden bridge 65 feet high, with a very strong curvature and a gradient of 4 per cent (211 feet per mile). As you feel the engine laboring up the steep ascent, and, looking out, find yourself on the edge of a precipitous bank, and almost face to face with the hindmost car, while the train bends around the curve, it is difficult to resist the sense of insecurity. It is certainly greatly to the credit of the management of the line that no accident has occurred under circumstances where the least carelessness would be fatal.* It gives one an idea of the labor expended on this railroad, to learn that for the great tunnel alone, now almost completed (one of fourteen), a corps of some three * Some weeks after this I chanced to ask a beautiful young Brazilian woman, recently married, whether she had ever been over this temporary road for the sake of seeing the picturesque scenery. "No," she answered with perfect seriousness, " I am young and very happy, and I do not wish to die yet." It was an amusing comment on the Brazilian estimate of the dangers attending the journey. RIO DE JANEIRO AND ITS ENVIRONS. 57 hundred men, relieving each other alternately, have been at work day and night, excepting Sundays, for seven years. The sound of hammer and pick during that time has hardly ever been still, and so hard is the rock through which the tunnel is pierced, that often the heaviest blows of the sledge yield only a little dust, — no more in bulk than a pinch of snuff.* On our return we were detained for half an hour at a station on the bank of the river Parahyba. This first visit to one of the considerable rivers of Brazil was not without its memorable incident. One of our friends of the Colorado, who parts from us here on his way to San Francisco, said he was determined not to leave the expe- * This road, which is but the beginning of railroad travel in Brazil, opens a rich prospect for scientific study. From this time forward the difficulty of transporting collections from the interior to the seaboard will be diminish- ing. Instead of the few small specimens of tropical vegetation now preserved in our museums, I hope that hereafter, in every school where geology and palaeontology are taught, we shall have large stems and portions of trunks to show the structure of palms, tree-ferns, and the like, — trees which represent in modern times the ancient geological forests. The time is coming when our text-books of botany and zoology will lose their local, limited character, and present comprehensive pictures of Nature in all her phases. Then only will it be possible to make true and pertinent comparisons between the condi- tion of the earth in former times and its present aspect under different zones and climates. To this day the fundamental principle guiding our identification of geological formations in different ages rests upon the assumption that each period has had one character throughout ; whereas the progress of geology is daily pressing upon us the evidence that at each period different latitudes and different continents have always had their characteristic animals and plants, if not as diversified as now, at least varied enough to exclude the idea of uni- formity. Not only do I look for a vast improvement in our collections with improved methods of travel and transportation in Brazil, but I hope that scientific journeys in the tropics will cease to be occasional events in the progress and civilization of nations, and will be as much within the reach of every student as journeys in the temperate zone have hitherto Urn.

He improvised a fishing apparatus, with a stick, a string, and a crooked pin, and caught two fishes, our first harvest from the fresh waters of Brazil, one of which was en- tirely new to Mr. Agassiz, while the other he had never seen, and only knew from descriptions. April 2St7i. — This morning we went over to the Colorado, which still lies in the harbor, and where the visit of the Emperor was expected. We all felt an interest in the occasion, for we have a kind of personal pride in the fine ship whose first voyage has been the source of so much enjoyment to us. The Imperial yacht arrived punc- tually at twelve o'clock, and was received by the captain with a full salute from his Parrott guns, fired with a prompt- ness and accuracy which the Emperor did not fail to notice. His Majesty went over the whole steamer ; and really an exploring expedition over such a world in little, with its provision-shops, its cattle -stalls, its pantries and sculleries, its endless accommodations for passengers and freight, its variety of decks and its great central fires, deep below all, is no contemptible journey for a tropical morning. The arrangements of the vessel seemed to excite the in- terest and admiration both of the Emperor and his suite. Captain Bradbury invited his Majesty to lunch on board ; he very cordially accepted, and remained some time after- ward, conversing chiefly about scientific subjects, and es- pecially on matters connected with the expedition. The Emperor is still a young man ; but though only forty, he has been the reigning sovereign of Brazil for more than half that time, and he looks careworn and somewhat older than his years. He has a dignified, manly presence, a face rather stern in repose, but animated and genial in conversa- tion ; his manner is courteous and friendly to all. RIO DE JANEIRO AND ITS ENVIRONS. 59 May 1st. — We celebrated May-day in a strange land, where May ushers in the winter, by driving to the Botanical Garden. When I say we, I mean usually the unprofessional members of the party. The scientific corps are too busily engaged to be with us on many of our little pleasure excursions. Mr. Agassiz himself is chiefly occupied in seeing numerous persons in official positions, whose influ- ence is important in matters relative to the expedition. He is very anxious to complete these necessary prelimi- naries, to despatch his various parties into the interior, and to begin his personal investigations. He is commended to be patient, however, and not to fret at delays ; for, with the best will in the world, the dilatory national habits cannot be changed. Meanwhile he has improvised a laboratory in a large empty room over a warehouse in the Rua Direita, the principal business street of the city. Here in one corner the ornithologists, Mr. Dexter and Mr. Allen, have their bench, — a rough board propped on two casks, the seat an empty keg ; in another, Mr. Anthony, with an apparatus of much the same kind, pores over his shells ; a dissecting-table of like carpentry occupies a conspicuous position ; and in the midst the Professor may generally be seen sitting on a barrel, for chairs there are none, assorting or examining specimens, or going from bench to bench to see how the work progresses. In the midst of the confusion Mr. Burkhardt has his little table, where he is making colored drawings of the fish as they are brought in fresh from the fishing-boats. In a small adjoining room Mr. Sceva is preparing skeletons for mounting. Every one, in short, has his special task and is busily at work. A very questionable perfume, an " ancient and fish-like smell," strongly tinged with alcohol, guides one to this abode »t 60 A JOURNEY IN BRAZIL. Science, where, notwithstanding its unattractive aspect, Mr. Agassiz receives many visitors, curious to see the actual working process of a laboratory of Natural History, and full of interest in the expedition. Here also pour in specimens from all quarters and of every kind ; voluntary contributions, which daily swell the collections.* Those of the party who are not engaged here have their work else- where. Mr. Hartt and Mr. St. John are at various stations along the railroad line, making geological sections of the road ; several of the volunteers are collecting in the country, and Mr. Hunnewell is studying at a photograph- ic establishment, fitting himself to assist Mr. Agassiz in this way when we are beyond the reach of professional artists. , Our excursion of to-day took us to another of those exquisite drives in the neighborhood of the city, always along the harbor or some inlet of it, always in sight of the mountains, always bordered by pretty country houses and gardens. The Botanical Garden is about eight miles from the centre of the town. It is beautiful, because the situation is admirably well chosen, and because anything * Among the frequent visitors at the laboratory, and one to whom Mr. Agassiz was indebted for most efficient aid in making his collection of fishes from the harbor of Rio, was our friend Dr. Pacheco de Silva, who never lost an opportunity of paying us all sorts of friendly attentions. He added quite a number of luxuries to the working-room described above. Another friend who was often at the laboratory was Dr. Nageli. Notwithstanding his large practice, he found time to assist Mr. Agassiz not only with collections but with drawings of various specimens. Being himself an able naturalist, his co-operation was very valuable. The collections were indeed enriched by contributions from so many sources that it would be impossible to enumerate them all here. In the more technical reports of the expedition all such gifts are recorded, with the names of those persons from whom the specimens were received. V.

But it is not kept with great care. Indeed, the very readiness with which plants respond to the least culture bestowed upon them here makes it very difficult to keep grounds in that trim order which we think so essential. This garden boasts, however, one feature as unique as it is beautiful, in its long avenue of palms, some eighty feet in height. I wish it were possible to give in words the faintest idea of the archi- tectural beauty of this colonnade of palms, with their green crowns meeting to form the roof. Straight, firm, and smooth as stone columns, a dim vision of colonnades in some ancient Egyptian temple rises to the imagination as one looks down the long vista.* May 6th. — Yesterday, at the invitation of our friend Mr. B , we ascended the famous Corcovado peak. Leav- ing the carriages at the terminus of the Larangeiras road, we made the farther ascent on horseback by a winding narrow path, which, though a very fair road for mountain travelling in ordinary weather, had been made exceedingly slippery by the late rains. The ride was lovely through the fragrant forest, with enchanting glimpses of view here and there, giving promise of what was .before us. Occa- sionally a brook or a little cascade made pleasant music by the roadside, and when we stopped to rest our horses we heard the wind rustle softly in the stiff palms overhead. The beauty of vegetation is enhanced here by the singular character of the soil. The color of the earth is peculiar all about Rio ; of a rich warm red, it seems to glow beneath the mass of vines and large-leaved plants above it, and every now and then crop^ out in vivid, striking * The palm is the beautiful Oreodoxa oleracea. 62 A JOURXEY IN BRAZIL. contrast to the surrounding verdure. Frequently our path followed the base of such a bank, its deep ochre and ver- milion tints looking all the softer for their framework of green. Among the larger growth, the Candelabra-tree {Cecropia) was conspicuous. The strangely regular struc- ture of the branches and its silvery-tinted foliage make it stand out in bold relief from the darker background. It is a striking feature of the forest in this neighborhood. A wide panoramic prospect always eludes description, but certainly few can combine such rare elements of beauty as the one from the summit of the Corcovado. The immense landlocked harbor, with its gateway open to the sea, the broad ocean beyond, the many islands, the circle of moun- tains with soft fleecy clouds floating about the nearer peaks, — all these features make a wonderful picture. One great charm of this landscape consists in the fact, that, though very extensive, it is not so distant as to deprive objects of their individuality. After all, a very distant view is something like an inventory : so many dark, green patches, forests ; so many lighter green patches, fields ; so many white spots, lakes ; so many silver threads, rivers, &c. But here special effects are not lost in the grandeur 'of the whole. On the extreme peak of the height a wall has been built around the edge, the descent on one side being so vertical that a false step might hurl one to instant destruction. At this wall we dismounted and lingered long, unwilling to leave the beautiful view before sunset. We were, however, anxious to return by daylight, and, to confess the truth, being a timorous and inexperienced rider at best, I was not without some anxiety as to the descent, for the latter part of the slippery road had been a sheer scramble. Putting a bold face on the matter, EIO DE JANEIRO AND ITS ENVIRONS. 63 however, I resumed my seat, trying to look as if it were my habit to mount horses on the tops of high mountains and slide down to the bottom. This is really no inaccurate description of our descent for the first ten minutes, after which we regained the more level path at the little station called " the Pameiras." We are told to-day that parties usually leave their horses at this station and ascend the rest of the way on foot, the road beyond that being so steep that it is considered unsafe for riding. However, we reached the plain without accident, and I look back upon yesterday's ride with some complacency as a first lesson in mountain travelling.* May 20th. — On Friday, the 12th of May, we left Rio on our first excursion of any length. A day or two after our arrival Mr. Agassiz had received an invitation from the President of the Union and Industry Company to go with some of his party over their road from Petropolis to Juiz de Fora, in the Province of Minas Geraes, a road celebrated not only for the beauty of its scenery, but also for its own excellence. A word as to the circumstances under which it has been built may not be amiss here ; and it must be confessed, that, if the Brazilians are, as they are said to be, slow in their progress, the improvements they do un- dertake are carried out with great thoroughness. It is true that the construction of the road has been intrusted to French engineers, but the leading man in its projec- tion and ultimate completion has been a Brazilian, Senhor * Leuzinger's admirable photographs of the scenery about the Corcovado, as well as from Petropolis, the Organ Mountains, and the neighborhood of Rio generally, may now be had in the print-shops of Boston and New York. I am the more desirous to make this fact known as I am indebted to Mr. Leuzinger for very generous assistance in the illustration of scientific ob- jects. — L. A. 64 A JOURNEY IN BRAZIL. Mariano Procopio Ferreira Lage, a native of the province of Minas Geraes. This province is said to be remarkable for the great energy and intelligence of its inhabitants, as compared with those of the adjoining provinces. Per- haps this may be owing to its cooler climate, most of its towns lying among the highlands of the Serras, and en- joying a fresher, more stimulating air than those nearer the sea-coast. Before undertaking the building of this road, Senhor Lage travelled both in Europe and America with the purpose of learning all the modern improvements in works of a similar character. The result bears testimony to the energy and patience with which he has carried out his project.* Twelve years ago the only means of going into the interior from Petropolis was through narrow, dangerous, broken mule-tracks, and a journey of a hundred miles involved a difficult ride of three or four days. Now one travels from Petropolis to Juiz de Fora between sunrise and sunset over a post-road equal to any in the world, changing mules every ten or twelve miles at pretty little stations, built somewhat in the style of Swiss chalets, each one of which is a settlement for the German colonists who have been induced to come out as workmen on the road. This emigration in itself is a great advantage to the country ; wherever these little German villages occur, nestled down among the hills, there are the neat vege- table and flower gardens, the tidy houses, the general aspect of thrift and comfort, so characteristic of the better classes of the German peasantry. Nominally no slaves are * A commemorative tablet, set in the rocks on the dividing line between the provinces of Rio de Janeiro and Minas Geraes, recording the speech of the Emperor on the occasion of the opening of the road, testifies the appreciation in which this undertaking was held by the government of Brazil. RIO DE JANEIRO AND ITS ENVIRONS. 65 allowed on the service of the road, Portuguese and German workmen being chiefly employed. This is a regulation which applies not only here, but on other public works about Rio. The contracts granted by the government expressly exclude the employment of slaves, though un- fortunately this rule is not adhered to strictly, because for the performance of certain kinds of work no substitute for slave labor has yet been found. In the direct care of the road, however, in the repairs, for instance, re- quiring gangs of men who are constantly at work blasting rock and cracking the fragments into small pieces for the fresh macadamizing of any imperfect spot, mending any defects in the embankments or walls, &c., none but free labor is employed. This attempt to exclude slaves from the public works is an emancipation movement, undertaken with the idea of gradually limiting slave labor to agricultural processes, and ridding the large cities and their neighborhood of the presence of slavery. The subject of emancipation is no such political bugbear here as it has been with us. It is very liberally and calmly discussed by all classes ; the general feeling is against the institution, and it seems to be taken for granted that it will disappear before many years are over. During this very session of the Assem- bly one or two bills for emancipation have been brought forward. Even now any enterprising negro may obtain his freedom, and, once obtained, there is no obstacle to his rising in social or political station. But while from this point of view slavery is less absolute than it was with us, it has some appalling aspects. The slaves, at least in the cities, are literally beasts of burden. One sees the most cumbersome furniture, — pianos and the like, 5 66 A JOURNEY IN BRAZIL. and the heaviest trunks or barrels, piled one on top of the other, or bales of sugar and coffee weighing hundreds of pounds, — moving about the streets on the heads of the negroes. The result of this is that their limbs often become crippled, and it is common to see negroes in the prime of life who are quite crooked and maimed, and can hardly walk without a stick to lean upon. In justice I must add, however, that this practice, though it shocks a stranger even now, is gradually disappearing. We are told that a few years ago there were hardly any baggage- wagons except these living ones, and that the habit of using the blacks in this way is going out of vogue. In this as in other matters the Emperor's opinions are those of an enlightened and humane man, and were his power equal to his will, slavery would vanish from his dominions at once. He is, however, too wise not to know that all great social changes must be gradual ; but he openly declares his abhorrence of the system.* But to return from this digression to the road of the Union and Industry Company. It is now completed as far as Juiz de Fora, affording every convenience for the transport of the rich harvest of coffee constantly travelling over it from all the fazendas in the region. As the whole district is very rich in coffee-plantations, the improvement in the means of transportation is of course very im- portant to the commercial interests of the country, and * Since this was written the Emperor, at a large pecuniary sacrifice, has liberated all the slaves belonging to the property of the crown, and a general scheme of emancipation has been announced by the Brazilian government, the wisdom, foresight, and benevolence of which can hardly be too highly praised. If this be adopted, slavery in Brazil will disappear within the century by a gradual process, involving no violent convulsion, and perilling neither the safety of the slave nor the welfare of his master. RIO DE JANEIRO AND ITS ENVIRONS. 67 Senhor Lage is making practicable roads to the smallest settlements in his neighborhood. He has not, however, been free from the difficulties which men encounter whose schemes are in advance of their surroundings. No doubt a great part of the dissatisfaction is owing to the fact that the road is not so remunerative as was anticipated, the advance of the Bom Pedro Railroad having impaired its success. Still it must be considered as a monument to the public spirit and energy of the men who undertook it. Not wishing to interrupt the course of the narrative, I have thought it best to preface the story of our journey by some account of this road, the building of which is a significant fact in the present history of Brazil. I will now take up again the thread of our personal adventures. Leaving the city at two o'clock in the ferry-boat, we kept up the harbor some fifteen miles. There was a cool breeze, and the day, though warm, was not oppressive. Passing the large Ilha do Governador, the smaller but exceedingly pretty island of Paqueta, and many others, with their palms, banana and acacia trees, dotting the harbor of Rio and adding another grace to its beauty, we landed in about an hour and a quarter at the little town of Maua.* Here we took the cars, and an hour's ride through low and marshy grounds brought us to the fcot of the Serra (Raiz da Serra), where we left the rail- road for the post-coach, which runs regularly from this station. The drive was delightful, in an open diligence drawn by four mules on the full gallop over a road as smooth as a floor. It wound zigzag up the mountains, * To the Baron de Maua, a leader in the great improvements now going on in Brazil, the citizens of Rio de Janeiro owe their present convenient road to Fetropolis, their favorite summer residence. 68 A JOURNEY IN BRAZIL. through the wildest scenery, while below us lay the valley broken into a billowy sea of green hills, and the harbor with the coast range beyond, growing soft and mellow in the afternoon sunshine. To complete the picture, one must clothe it in palms and acacias and tree-ferns, and drape it in a tangle of parasitic growth, with abundant bloom of the purple Quaresma (Flower of Lent),* the Thunbergia vine, with its little straw-colored blossoms creeping over every wall and shrub, and the blue and yellow Bignonias. We are constantly astonished at the variety of palms. A palm is such a rarity in our hot- houses, that we easily forget how numerous and varied they are in their native forests. We have the scarlet-oak, the white-oak, the scrub-oak, the chestnut-oak, the swamp- oak, and many others. And so in the tropical forest there is the cocoanut-palm, with its swollen, bulb-like stem when young, its tall, straight trunk when full grown, its cluster of heavy fruit, and its long, plume-like, drooping flower ; f the Coccoeiro, with its slighter trunk and pendant branch- es of small berry-like fruit ; the Palmetto, with its tender succulent bud on the summit of the stem, which is used as a vegetable here, and makes an excellent substitute for cabbage ; the thorny Icaree or Cari, a variety of fan- palms, with their leaves cut like ribbons ; and very many others, each with its characteristic foliage and appearance. * A species of Melastoma, with very large, conspicuous flowers. — L. A. t This is not, however, native to Brazil. J Indeed, their diversity is much greater even than that of our Oaks, and it would require a comprehensive comparison with a majority of our forest-trees to match the differences they exhibit among themselves ; and their native names, far more euphonic than the systematic names under which they are entered in our scientific works, are as familiar to the Indians as those of our beeches, birches, hazels, chestnuts, poplars, or willows to our farmers. There RIO DE JANEIRO AND ITS ENVIRONS. 69 The mountains along the road, as indeed throughout the neighborhood of Rio, are of very peculiar forms, steep and conical, suggesting at first sight a volcanic origin. It is this abruptness of outline which gives so much grandeur to mountain ranges here, the average height of which does not exceed two or three thousand feet. A closer examina- tion of their structure shows that their wild, fantastic forms are the result of the slow processes of disintegration, not of sudden convulsions. Indeed, the rocks here differ so much in external character from those of the Northern Hemisphere, that the European geologist stands at first bewildered before them, and feels that the work of his life is to be done over again. It is some time before he obtains a clew to the facts and brings them into harmony with his previous knowledge. Thus far Mr. Agassiz finds himself painfully perplexed by this new aspect of phenome- na so familiar to him in other regions, but so baffling here. are four essentially different forms among the palms : the tall ones, with a slender and erect stem, terminating with a crown of long feathery leaves, or with broad fan-shaped leaves ; the bushy ones, the leaves of which rise as it were in tufts from the ground, the stem remaining hidden under the foliage ; the brush-like ones, with a small stem, and a few rather large leaves ; and the winding, creeping, slender species. Their flowers and fruits are as varied as their stock. Some of these fruits may be compared to large woody nuts, with a fleshy mass inside ; others have a scaly covering ; others resemble peaches or apricots, while others still are like plums or grapes. Most of them are eatable and rather pleasant to the taste. It is a thousand pities that so many of these majestic trees should have been deprived of their sonorous native names, to bear henceforth, in the annals of science, the names of some unknown princes, whom flattery alone could rescue from oblivion. The Innja has become a Maximiliana, the Jara a Leopoldinia, the Pupunha a Guilielma, the Pachiuba an Iriartea, the Canina a Mauritia. The changes from Indian to Greek names have not been more felicitous. I would certainly have preferred Jacitara to Desmonchus, Mucaja to Acrocomia, Baccaba to CEnocarpus, Tucuma to Astrocaryum. Even Euterpe for Assai is hardly an improvement. — L. A. 70 A JOURNEY IN BRAZIL. He comes upon a rock, for instance, or a rounded elevation which by its outline he would suppose to be a " roche mou- tonnee," but approaching it more nearly he finds a decom- posed crust instead of a glaciated surface. It is the same with the loose materials corresponding to the drift of the Northern hemisphere, and with all boulders or detached masses of rock ; on account of their disintegration wher- ever they are exposed to the atmosphere, nothing is to be learned from their external appearance. There is not a natural surface of rock, unless recently broken, to be found anywhere. The sun had set before we drove into the pretty town of Petropolis, the summer paradise of all Rio Janeirans whose circumstances enable them to leave the heat and dirt and vile smells of the city, for the pure air and enchanting views of the Serra. In a central position stands the summer palace of the Emperor, a far gayer and more cheerful-looking edifice than the palace at San Christovao. Here he passes six months of the year. Through the midst of the town runs the pretty river Piabanha, a shallow stream, now rippling along in the bottom of its bed between high green banks ; but we were told that a night of rain in the hot season is enough to swell its waters till they overflow and flood the road. I could not but think how easy it would be for any one who cares to see tropical scenery to come here, when the direct line of steamers from New York is established, and, instead of going to Newport or Nahant, to take a house in Petropo- lis for the summer. It commands all the most beautiful scenery about Rio, and the horseback rides are without end. During our summer the weather is delightful here, just admitting a semblance of wood-fire morning and even- RIO DE JANEIRO AND ITS ENVIRONS. 71 ing, while the orange orchards are golden with fruit, and flowers are everywhere. We had little time to become acquainted with the beauty of the place, which we hope to explore more at our leisure on some future visit, for sunrise the next morning saw us on our road again. The soft clouds hanging over the tops of the mountains were just tinged with the first rays of the sun when we drove out of the town on the top of the diligence, the mules at full gallop, the guard sounding a gay reveille as we rattled over the little bridge and past the pretty houses where closed windows and doors showed that the inhabitants were hardly yet astir. The first part of our road lay through the lovely valley of the Piabanha, the river whose acquaintance we had already made in Petropolis, and which accompanied us for the first forty or fifty miles of our journey, sometimes a restless stream broken into rapids and cascades, sometimes spread- ing into a broad, placid river, but always enclosed between mountains rising occasionally to the height of a few thou- sand feet, lifting here and there a bare rocky face seamed with a thousand scars of time and studded with Bromelias and Orchids, but more often clothed with all the glory of the Southern forest, or covered from base tb summit with coffee shrubs. A thriving coffee plantation is a very pretty sight ; the rounded, regular outline of the shrubs gives a tufted look to the hillside on which they grow, and their glittering foliage contrasts strikingly at this season with their bright red berries. One often passes coffee planta- tions, however, which look ragged and thin ; in this case the trees are either suffering from the peculiar insect so injurious to them, (a kind of Tinea,) or have run out and become exhausted. As we drove along, the scenes 72 A JOURNEY IN BRAZIL. upon the road were often as amusing as they were pic- turesque. Now we came upon a troop of pack mules with a tropeiro (driver) at their head ; if a large troop, they were divided into companies of eight, with a man to guide each company. The guard wound his horn to give warning of our coming, and a general struggle, gar- nished with kicks, oaths, and many lashes, ensued, to induce the mules to make way for the coach. These troops of mules are beginning to disappear from the sea- board since the modern improvements in railroads and stage lines, making transportation so much easier ; but until lately it was the only way of bringing down the produce from the interior. Or again we fell in with a line of country wagons made of plaited bamboo, a kind of fabric which is put to a variety of uses here, such as the building of fences and lining of ceilings or roofs, as well as the construction of carts. Here and there the laborers were sitting in groups at the roadside, their work suspended while they cooked their midday meal, their kettles hanging over the fire, their coffee-pot simmering over the coals, and they themselves lying about in gypsy-like freedom of attitude. At Posse, the third stage of Our road, after having gone some thirty miles, we also stopped to breakfast, a meal which was by no means unacceptable after our three hours' ride. It is an almost universal custom with the Brazilians, especially when travelling, to take their cup of black coffee on rising, and defer their more solid break- fast till ten or eleven o'clock. I do not know whether my readers will sympathize with me, but I am always dis- appointed myself if any book of travels, having led me along the weary road, does not tell me what the hungry RIO DE JANEIRO AND ITS ENVIRONS. 73 wanderers had to eat. It seems hardly fair, having shared their fatigues, that I should not also share their refresh- ment and be invited to sit down at table with them. Doing, therefore, as I would be done by, I shall give our bill of fare, and take an opportunity of saying a word at the same time of the characteristic Brazilian dishes. In the first place we had black beans stewed with came secca (dried meat), the invariable accompaniment of every meal in Brazil. There is no house so poor that it does not have its feijoes, no house so rich as to exclude this homely but most excellent dish, a favorite alike with high and low. Then there was chicken stewed with potatoes and rice, almost as marked a feature of the Brazilian cuisine as the black beans. Beside these, there were eggs served in various ways, cold meat, wine, coffee, and bread. Vegetables seem to be rare, though one would expect a plentiful variety in this climate.* At Posse Mr. Agassiz found a cordial co-operator in Mr. Charles Taylor, who expressed a warm interest in his scientific researches, and kept one of the collecting cans that he might fill it with fishes from the neighboring rivers and streams. f Our kind friend Senhor Joao Baptista da Fonseca, who was our guide and our host on this journey, had neglected nothing which could contribute to the success * This observation was confirmed by our year's travel. The Brazilians care little for a variety of vegetables, and do not give much attention to their culti- vation. Those they do use are chiefly imported in cans from Europe. t On our return from the Amazons a year later we heard with great regret of the death of Mr. Taylor For many months he took an active part in the objects of the Expedition, being himself a good naturalist, and not only made valuable collections for Mr. Agassiz, but also some admirable colored draw- ings of fishes and insects, which it is hoped may be published at a future time with the other scientific results of this journey. 4 74 A JOURNEY IN BRAZIL. and pleasure of the party, and had so prepared the way for the scientific objects of the excursion that at several points of the road we found collections of fishes and other animals awaiting us by the roadside. Once or twice, as we passed a fazenda, a negro carrying a basket came out to stop the diligence, and, lifting the cool green leaves which covered them, showed freshly caught fishes of all hues and sizes. It was rather aggravating, especially as we ap- proached the end of our long drive, and the idea of dinner readily suggested itself, to see them disappear in the alcohol cans.* At about midday we bade good by to the pretty river we had followed thus far, and at the Estagao d'Entre Rios (between the rivers) crossed the fine bridge which spans the Parahyba at this point. The Parahyba is the large river which *flows for a great part of its course between the Serra do Mar and the Serra da Mantiqueira, emptying into the Atlantic at San Joao da Barra considerably to the northeast of Rio de Janeiro. One is a little bewildered at first by the variety of Serras in Brazil, because the * My experience of this day might well awaken the envy of any naturalist, and I was myself no less astonished than grateful for its scientific results. Not only had Senhor Lage provided us with the most comfortable private con- veyance, but he had sent messengers in advance to all the planters residing near our line of travel, requesting them to provide all the fishes that were to be had in the adjoining rivers and brooks. The agents of the stations situated near water-courses had also received instructions to have similar collections in readiness, and in two places I found large tanks filled with living specimens of all the species in the neighborhood. The small number of species subsequently added, upon repeated excursions to different parts of the basin of the Parahyba, convinced me that in this one day, thanks to the kindness of our host and his friends, I had an opportunity of examining nearly its whole ichthyological fauna, and of making probably as complete a collection from it as may be found from any of the considerable rivers of Europe in the larger museums of the Old World.— L. A. RIO DE JANEIRO AND ITS ENVIRONS. 75 word is used to express not only important chains of mountains, but all their spurs. Any mountainous eleva- tion is a Serra ; but though there is an endless number of them between the Serra do Mar and the Serra da Manti- queira, these are the two most important chains, running parallel with the sea-coast. Between them flows the Para- hyba with its many branches. It is important to make col- lections here, as the peculiar character of this water basin, the many tributaries of which drain the southern water- shed of the Serra da Mantiqueira, and the northern water- shed of the Serra do Mar, make it of especial interest for the naturalist. On account of its neighborhood to the sea, it is also desirable to compare its inhabitants with those of the many short, disconnected rivers which empty into the Atlantic on the other side of the coast range. In short, it gives a good opportunity for testing those questions of the geographical distribution of living beings, as connected with their origin, which Mr. Agassiz so strongly urged upon his assistants during our voyage. Soon after crossing the Parahyba, the road strikes the Parahybuna, a tributary which enters the main river on its northern side, nearly opposite the Piabanha. The latter part of the journey is less wild than the first half; the mountains fall away in somewhat gentler slopes, and do not shut in the road with the steep rugged precipices so striking in the valley of the Piabanha. But though perhaps less picturesque on approaching Juiz de Fora,* the scenery is beautiful enough throughout the whole ride to satisfy the most fastidious and keep the attention constantly awake. We arrived at the end of our journey at about six o'clock, and found most comfortable accommodations prepared for * In some maps this place is inscribed under the name of Parahybuna. 76 A JOURNEY IN BRAZIL. us at a little cottage, built somewhat in the style of a Swiss chalet, and kept by the company for the use of their guests or for the directors of the road. An excellent dinner awaited us at the little hotel just opposite, the door of which is shaded by two stately palms ; and with a ramble in the neighboring grounds of Senhor Lage, and a concert by a band of German musicians, consisting of employees on the road, our day closed, — a day full of pleasure. The following morning we were indebted to Senhor Lage for a walk, as instructive as it was charming, through his gardens and orange orchards. Not only has he arranged his grounds with exquisite taste, but has endeavored to bring together the shrubs and trees most characteristic of the country, so that a stroll through his place is a valuable lesson to the botanist, the more so if he is fortunate enough to have the proprietor as a companion, for he may then learn the name and history of every tree and flower he passes. Such a guide is invaluable here, for the Brazilians seem to remain in blissful ignorance of systematic nomen- clature ; to most of them all flowers are " flores," all animals, from a fly up to a mule or an elephant, " bixos." One of the most beautiful features of Senhor Lage's grounds is a plantation of parasites, — an extensive walk, bordered on either side by a rustic fence, over which are trained some of the most exquisite parasitic plants of the Brazilian forests. In the midst of this walk is the Grotto of the Princesses, so called after the daughters of the Em- peror who, on occasion of a visit made by the Imperial family to Juiz de Fora, at the opening of the road, were exceedingly pleased with this pretty spot, where a spring all overhung with parasitic vines, Orchids, &c. flows out from the rock. The spring, however, is artificial, and is a part RIO DE JANEIRO AND ITS ENVIRONS. 77 of the admirable system of irrigation introduced over the whole estate. So rapid is the growth of everything here that one can hardly believe this beautiful country place to have been under cultivation only five or six years ; a few years more under the same direction will make it a tropi- cal paradise. A variety of plans combining pleasure and science had been arranged for the next day. First on the list was a drive to the " Forest of the Empress." Everything of any interest in the neighborhood recalls the visit of the Im- perial family at the opening of the road. From this event all loyal Juiz de Forans date, and the virgin forest we were to visit is consecrated by the fact that on this great occasion the Emperor with his family and suite breakfasted here in presence of a numerous assemblage of their loving subjects. Surely a more stately banqueting-hall could scarcely be found. The throne was cut in the broad buttressed trunk of a huge figueira ; the rustic table, built of rough stems, stood under the shadow of great palm-trees ; and around was the tropical forest, tapestried with vines, and embroi- dered with Orchids. These were royal accompaniments, even though the whole entertainment was conducted with a simplicity in harmony with the scene. Neither gold nor silver nor glass was brought to vie with the beauties of nature ; the drinking-cups were made from the hollow stems of the wild bamboo-tree, and all the service was of the same rustic description. The tables, seats, LIFE IN RIO CONTINUED. 81 thrown out from a romantic-looking road, and as we found no carriage on the wharf, and ascertained that the boat did not return for two hours, we wandered up this road to see where chance would lead us. The afternoon would have been full of interest had it ended in the walk along the crescent-shaped bay, with the water rippling on the sands, and the mountains opposite all purple in the afternoon sunshine. The road brought us, however, to a magnifi- cent hospital for the insane, the hospital of Dom Pedro Se- gundo, which we had seen and admired from the deck of the steamer on the day of our arrival. We entered the grounds, and as the great door of the building was open and the official on guard looked by no means forbidding, we ascended the steps and went in. It is difficult to imagine an edifice more appropriate for the purpose to which it is devoted. It is true we saw only the public rooms and corridors, as a permit was required to enter the wards ; but a plan hanging near the entrance gave us an idea of the arrangement of the building, and its general aspect bore testimony to the cleanliness, cheerful- ness, and order of the establishment. Some of the public rooms were very handsome, — especially one, at the end of which stands a statue of the boy Emperor, taken, no doubt, at the time of his coronation. In the man of forty you still recognize the frank, intelligent, manly face of the lad on whom such great responsibility was thrown at the age of fifteen. As we went up the spacious stair- case, the sound of music brought us to the door of the chapel, where the evening service was going on. Patients and nurses were kneeling together ; a choir of female voices was singing sweetly a calm, peaceful kind of music ; that somewhat monotonous chanting, so passion- 4* F 82 A JOURNEY IN BRAZIL. less in its regular movement, which one hears in the Catholic Church ; the candles were burning before the altar, but the great window just outside the door was open to the setting sun, and, as I stood in the balcony looking out on the mountains and listening to the music, I thought that a mind which had gone astray might find its way back again in such scenes and under such influences. Certainly, if nature has any healing power, it must be felt here. We lingered and listened as long as we dared, and stole away as the services were closing, just in time to take the evening boat. May 25th. — The fish-market is, in all seaport towns, a favorite haunt with Mr. Agassiz, and here it has an especial interest for him on account of the variety and beauty of the fishes brought in every morning. I sometimes accompany him in these rambles for the pleasure of seeing the fresh loads of oranges, flowers, and vegetables, and of watch- ing the picturesque negro groups selling their wares or sitting about in knots to gossip. We have already learned that the fine-looking athletic negroes of a nobler type, at least physically, than any we see in the States, are the so-called Mina negroes, from the province of Mina, in Western Africa. They are a very powerful-looking race, and the women especially are finely made and have quite a dignified presence. I am never tired of watching them in the street and market, where they are to be seen in numbers, being more commonly employed as venders of fruit and vegetables than as house-servants. It is said that a certain wild and independent element in their character makes them unfit for domestic service. The women always wear a high muslin turban, and a long, bright-colored snawl, either crossed on the breast and thrown carelessly over the LIFE IN EIO CONTINUED. 83 Mina Negress. shoulder, or, if the day be chilly, drawn closely around them, their arms hidden in its folds. The amount of ex- pression they throw into the use of this shawl is quite amazing. I watched a tall, superbly made woman in the street to-day who was in a great passion. Gesticulating vio- lently, she flung her shawl wide, throwing out both arms, then, drawing it suddenly in, folded it about her, and stretched herself to her full height ; presently opening it once more, she shook her fist in the face of her opponent, 84 A JOURNEY IN BRAZIL. Mina Negress and Child. and then, casting one end of her long drapery over her shoulder, stalked away with the air of a tragedy queen. It serves as a cradle also, for, tying it loosely round their hips, they slip the baby into the folds behind, and there it hangs, rocked to sleep by the mother's movement as she walks on with her long, swinging tread. The Mina ne- gress is almost invariably remarkable for her beautiful hand and arm. She seems to be conscious of this, and usually wears close-fitting bracelets at the wrist, made of LIFE IN RIO CONTINUED. 85 some bright-colored beads, which set off the form of the hand and are exceedingly becoming on her dark, shining skin. These negroes are Mohammedans, and are said to remain faithful to their prophet, though surrounded by the observances of the Catholic Church. They do not seem to me so affable and responsive as the Congo negroes, but are, on the contrary, rather haughty. One morning I came upon a cluster of them in the market breakfasting after their work was done, and I stopped to talk with them, ask- ing what they had for breakfast, and trying various subjects on which to open an acquaintance. But they looked at me coldly and suspiciously, barely answering my questions, and were evidently relieved when I walked away. May 26^A. — Tijuca. In the pleasant environs of Rio there is no resort more frequented than the establishment, of Mr. Bennett at Tijuca, and we were not sorry the day before yesterday to leave the hot, dusty city, with a pleasant party of friends, for this cluster of mountains, some eigh- teen hundred feet above the sea level and about eight miles from Rio. It takes its name from the peak of Tijuca, so conspicuous an object in the coast range. On our arrival we were very cordially welcomed by our host himself, who was not quite a stranger to us, for Mr. Agassiz has been already indebted to him for valuable collections. Mr. Ben- nett has an Englishman's love of nature, and is very fa- miliar with the botany and zoology of the beautiful region which has been his home for many years. Under his guid- ance, we have taken a number of pleasant rambles and rides, regretting only that we cannot avail ourselves for a longer time of his intimate knowledge of the locality and its productions. I have alluded before to the perplexing character of the 86 A JOURNEY IN BRAZIL. geology, and the almost universal decomposition of the rock surfaces, making it difficult to decipher them. The presence of the drift phenomena, so universal in the North- ern hemisphere, has been denied here ; but, in his long walk to-day, Mr. Agassiz has had an opportunity of ob- serving a great number of erratic boulders, having no connection with the rocks in place, and also a sheet of drift studded with boulders and resting above the partially stratified metamorphic rock in immediate contact with it. I introduce here a letter written by him to his friend, Professor Peirce of Harvard University, under the first impression of the day's experience, which will best explain his view of the subject. " May 27th, 1865, TIJUCA. " MY DEAR PEIRCE : — "Yesterday was one of the happiest days of my life, and I want to share it with you. Here I am at Tijuca, a clus- ter of hills, about eighteen hundred feet high and some seven or eight miles from Rio, in a charming cottage-like t hotel, from the terrace of which you see a drift hill with innumerable erratic boulders, as characteristic as any I have ever seen in New England. I had before seen sundry unmistakable traces of drift, but there was everywhere con- nected with the drift itself such an amount of decomposed rocks of various kinds, that, though I could see the drift and distinguish it from the decomposed primary rocks in place, on account of my familiarity with that kind of deposits, yet I could probably never have satisfied anybody else that there is here an equivalent of the Northern drift, had I not found yesterday, near Bennett's hotel at Tijuca, the most palpable superposition of drift and decomposed rocks, with a distinct line of demarcation between the two, of which I shall secure LIFE IN RIO CONTINUED. 87 a good photograph. This locality afforded me at once an opportunity of contrasting the decomposed rocks which form a characteristic feature of the whole country (as far as I have yet seen it) with the superincumbent drift, and of making myself familiar with the peculiarities of both deposits ; so that I trust I shall be able hereafter to dis- tinguish both, whether they are in contact with one another or found separately. These decomposed rocks are quite a new feature to me in the structure of the country. Imagine granite, gneiss, mica slate, clay slate, and in fact all the various kinds of rocks usually found in old metamorphic formations, reduced to the condition of a soft paste, ex- hibiting all the mineralogical elements of the rocks, as they may have been before they were decomposed, but now completely disintegrated and resting side by side, as if they had been accumulated artificially in the manner you have seen glass cylinders filled with variously colored sands or clays to imitate the appearance of the beds of Gay-Head. And through this loose mass there run, here and there, larger or smaller dikes of quartz-rock or of granite or other rocks equally disintegrated ; but they retain the arrangement of their materials, showing them to be disintegrated dikes in large disintegrated masses of rock ; the whole passing unmistakably to rocks of the same kind in which the decomposition or disintegration is only partial, or no trace of it visible, and the whole mass exhibiting then the appearance of an ordinary meta- morphic set of rocks. " That such masses forming everywhere the surface of the country should be a great obstacle to the study of the erratic phenomena is at once plain, and I do not therefore wonder that those who seem familiar with the country A JOURNEY IN BRAZIL. should now entertain the idea that the surface rocks are everywhere decomposed, and that there is no erratic forma- tion or drift here. But upon close examination it is easy to perceive that, while the decomposed rocks consist of small particles of the primitive rocks which they represent, with their dikes and all other characteristic features, there is not a trace of larger or smaller boulders in them ; while the superincumbent drift, consisting of a similar paste, does not show the slightest sign of the indistinct stratifica- tion characteristic of the decomposed metamorphic rocks below it, nor any of the decomposed dikes, but is full of various kinds of boulders of various dimensions. I have not yet traced the boulders to their origin ; but the majority consist of a kind of greenstone composed of equal amounts of a greenish black hornblende and feldspar. In Entre Rios on the Parahyba, I was told by an engineer on the road that in Minas Geraes iron mines are worked in a rock like these boulders. This week I propose to explore the Serra da Mantiqueira,* which separates the province of Rio from Minas, and may advance the question further. But you see that I need not go to the Andes to find erratics, though it may yet be necessary for me to go, in order to trace the evidence of glacier action in the accumulation of this drift ; for you will notice that I have only given you the evidence of extensive accumu- lations of drift similar in its characteristics to Northern drift. But I have not yet seen a trace of glacial action properly speaking, if polished surfaces and scratches and furrows are especially to be considered as such. "The decomposition of the surface rocks to the extent to which it takes place here is very remarkable, and points * Mr. Agassiz was prevented from making this excursion. LIFE IN RIO CONTINUED. 89 to a new geological agency, thus far not discussed in our geological theories. It is obvious here (and to-day with the pouring rain which keeps me in doors I have satis- factory evidence of it) that the warm rains falling upon the heated soil must have a very powerful action in accelerating the decomposition of rocks. It is like torrents of hot water falling for ages in succession upon hot stones. Think of the effect, and, instead of wondering at the large amount of decomposed rocks which you meet everywhere, you will be surprised that there are any rocks left in their primitive condition. It is, however, the fact, that all the rocks you see are encased, as it were, in a lining of the decomposed part of their surface ; they are actually covered with a rotten crust of their own substance. " Ever truly yours, " L. AGASSIZ." Among the objects of special interest which we have seen here for the first time are the colossal fruits of the Sapucaia-tree, a species of Lecythis, belonging to the same family as the Brazilian nuts. These fruits, of which there are a number of species, vary from the size of an apple to that of an ordinary melon ; they resemble an urn closed with a lid, and contain about fifty seeds as large as almonds. The woods all over these Tijuca hills are beautiful and wonderfully luxuriant ; but I lack names for the various trees. We are not yet familiar enough with the aspect of the forest to distinguish readily its different forms of vegetation ; and it is besides exceedingly difficult here to ascertain the common names of plants. The Brazilians do not seem to me observant of nature in its details ; at all events, I never get a satisfactory answer to the question I 90 A JOURNEY IN BRAZIL. ani constantly putting, " What do you call this tree or flower ? ' And if you ask a botanist, he invariably gives you the scientific, not the popular name, nor does he seem to be aware that any such exists. I have a due respect for nomenclature, but when I inquire the name of some very graceful tree or some exquisite flower, I like to receive a manageable answer, something that may fitly be introduced into the privacy of domestic life, rather than the ponderous official Latin appellation. We are struck with the variety of Melastornas in full flower now, and very conspicuous, from their large purple blossoms, and have remarked also several species of the Bombaceae, easily distinguished by their peculiar foliage and large cotton fruits. 9 The Cande- labra-tree (Cecropia) is abundant here, as throughout the neighborhood of Rio, and is covered at this season with fruit resembling somewhat the fruit of the bread-tree, but more slender and cylindrical in form. Large Euphorbias, of the size of forest-trees, also attract our attention, for it is the first time we have seen them except as shrubs, such as the " Estrella do Norte" (Poinsettia). But there is before Mr. Bennett's house a very large nut-tree, " No- gueira," of this family. The palms are numerous ; among them the Astrocaryum Cari, whose spiny stems and leaves make it difficult to approach, is very common. Its bunches of bright chestnut-brown fruit hang from between the leaves which form its crown, each bunch about a foot in length, massive and compact, like a large cluster of black Hamburg grapes. The Syagrus palm is also frequent ; it has a greenish fruit not unlike the olive in appearance, also hanging in large pendent bunches just below the leaves. The mass of foliage is everywhere knit together by parasitic vines without number, and every dead branch or fallen LIFE IN RIO CONTINUED. 91 trunk is overgrown by parasites. Foreign tropical trees are cultivated about the houses everywhere,- -bread-fruit i • ap - i ' '• in Fallen Trunk overgrown by Parasites. trees and Ameixas, a kind of plum of the hawthorn family, bananas, etc. The bamboo of the East Indies also is used to form avenues in Rio do Janeiro and its environs. The alleys of bamboo in the grounds of the palace at San Chris- tovao are among its most beautiful ornaments. Mr. Agassiz has been surprised to find that shrimps of considerable size are common in all the brooks and even in the highest pools of Tijuca. It seems strange to meet with Crustacea of marine forms in mountain streams. To-day we are kept in the house by a violent rain, but there is enough to do in looking over specimens, working up journals, writing letters,
