We left Rondon, Lyra, and Pyrineus to take observations, and the rest of us embarked for the last time on the canoes, and, borne swiftly on the rapid current, we pa.s.sed over one set of not very important rapids and ran down to Senhor Caripe's little hamlet of Sao Joao, which we reached about one o'clock on April 27, just before a heavy afternoon rain set in. We had run nearly eight hundred kilometres during the sixty days we had spent in the canoes. Here we found and boarded Pyrineus's river steamer, which seemed in our eyes extremely comfortable. In the senhor's pleasant house we were greeted by the senhora, and they were both more than thoughtful and generous in their hospitality. Ahead of us lay merely thirty-six hours by steamer to Manaos. Such a trip as that we had taken tries men as if by fire.

Cherrie had more than stood every test; and in him Kermit and I had come to recognize a friend with whom our friendship would never falter or grow less.

Early the following afternoon our whole party, together with Senhor Caripe, started on the steamer. It took us a little over twelve hours'

swift steaming to run down to the mouth of the river on the upper course of which our progress had been so slow and painful; from source to mouth, according to our itinerary and to Lyra's calculations, the course of the stream down which we had thus come was about 1,500 kilometres in length--about 900 miles, perhaps nearly 1,000 miles-- from its source near the 13th degree in the highlands to its mouth in the Madeira, near the 5th degree. Next morning we were on the broad sluggish current of the lower Madeira, a beautiful tropical river.

There were heavy rainstorms, as usual, although this is supposed to be the very end of the rainy season. In the afternoon we finally entered the wonderful Amazon itself, the mighty river which contains one tenth of all the running water of the globe. It was miles across, where we entered it; and indeed we could not tell whether the farther bank, which we saw, was that of the mainland or an island. We went up it until about midnight, then steamed up the Rio Negro for a short distance, and at one in the morning of April 30 reached Manaos.

Manaos is a remarkable city. It is only three degrees south of the equator. Sixty years ago it was a nameless little collection of hovels, tenanted by a few Indians and a few of the poorest cla.s.s of Brazilian peasants. Now it is a big, handsome modern city, with Opera house, tramways, good hotels, fine squares and public buildings, and attractive private houses. The brilliant coloring and odd architecture give the place a very foreign and attractive flavor in northern eyes.

Its rapid growth to prosperity was due to the rubber trade. This is now far less remunerative than formerly. It will undoubtedly in some degree recover; and in any event the development of the immensely rich and fertile Amazonian valley is sure to go on, and it will be immensely quickened when closer connections are made with the Brazilian highland country lying south of it.

Here we found Miller, and glad indeed we were to see him. He had made good collections of mammals and birds on the Gy-Parana, the Madeira, and in the neighborhood of Manaos; his entire collection of mammals was really noteworthy. Among them was the only sloth any of us had seen on the trip. The most interesting of the birds he had seen was the hoatzin. This is a most curious bird of very archaic type. Its flight is feeble, and the naked young have spurs on their wings, by the help of which they crawl actively among the branches before their feathers grow. They swim no less easily, at the same early age. Miller got one or two nests, and preserved specimens of the surroundings of the nests; and he made exhaustive records of the habits of the birds.

Near Mega.s.so a jaguar had killed one of the bullocks that were being driven along for food. The big cat had not seized the ox with its claws by the head, but had torn open its throat and neck.

Every one was most courteous at Manaos, especially the governor of the state and the mayor of the city. Mr. Robiliard, the British consular representative, and also the representative of the Booth line of steamers, was particularly kind. He secured for us pa.s.sages on one of the cargo boats of the line to Para, and thence on one of the regular cargo-and-pa.s.senger steamers to Barbados and New York. The Booth people were most courteous to us.

I said good-by to the camaradas with real friendship and regret. The parting gift I gave to each was in gold sovereigns; and I was rather touched to learn later that they had agreed among themselves each to keep one sovereign as a medal of honor and token that the owner had been on the trip. They were a fine set, brave, patient, obedient, and enduring. Now they had forgotten their hard times; they were fat from eating, at leisure, all they wished; they were to see Rio Janeiro, always an object of ambition with men of their stamp; and they were very proud of their membership in the expedition.

Later, at Belen, I said good-by to Colonel Rondon, Doctor Cajazeira, and Lieutenant Lyra. Together with my admiration for their hardihood, courage, and resolution, I had grown to feel a strong and affectionate friendship for them. I had become very fond of them; and I was glad to feel that I had been their companion in the performance of a feat which possessed a certain lasting importance.

On May 1 we left Manaos for Belen-Para, as until recently it was called. The trip was interesting. We steamed down through tempest and sunshine; and the towering forest was dwarfed by the giant river it fringed. Sunrise and sunset turned the sky to an unearthly flame of many colors above the vast water. It all seemed the embodiment of loneliness and wild majesty. Yet everywhere man was conquering the loneliness and wresting the majesty to his own uses. We pa.s.sed many thriving, growing towns; at one we stopped to take on cargo.

Everywhere there was growth and development. The change since the days when Bates and Wallace came to this then poor and utterly primitive region is marvellous. One of its accompaniments has been a large European, chiefly south European, immigration. The blood is everywhere mixed; there is no color line, as in most English-speaking countries, and the negro and Indian strains are very strong; but the dominant blood, the blood already dominant in quant.i.ty, and that is steadily increasing its dominance, is the olive-white.

Only rarely did the river show its full width. Generally we were in channels or among islands. The surface of the water was dotted with little islands of floating vegetation. Miller said that much of this came from the lagoons such as those where he had been hunting, beside the Solimoens--lagoons filled with the huge and splendid Victoria lily, and with ma.s.ses of water hyacinths. Miller, who was very fond of animals and always took much care of them, had a small collection which he was bringing back for the Bronx Zoo. An agouti was so bad- tempered that he had to be kept solitary; but three monkeys, big, middle-sized, and little, and a young peccary formed a happy family.

The largest monkey cried, shedding real tears, when taken in the arms and pitied. The middle-sized monkey was stupid and kindly, and all the rest of the company imposed on it; the little monkey invariably rode on its back, and the peccary used it as a head pillow when it felt sleepy.

Belen, the capital of the state of Para, was an admirable ill.u.s.tration of the genuine and almost startling progress which Brazil has been making of recent years. It is a beautiful city, nearly under the equator. But it is not merely beautiful. The docks, the dredging operations, the warehouses, the stores and shops, all tell of energy and success in commercial life. It is as clean, healthy, and well policed a city as any of the size in the north temperate zone. The public buildings are handsome, the private dwellings attractive; there are a fine opera-house, an excellent tramway system, and a good museum and botanical gardens. There are cavalry stables, where lights burn all night long to protect the horses from the vampire bats. The parks, the rows of palms and mango-trees, the open-air restaurants, the gay life under the lights at night, all give the city its own special quality and charm. Belen and Manaos are very striking examples of what can be done in the mid-tropics. The governor of Para and his charming wife were more than kind.

Cherrie and Miller spent the day at the really capital zoological gardens, with the curator, Miss Snethlage. Miss Snethlage, a German lady, is a first rate field and closet naturalist, and an explorer of note, who has gone on foot from the Xingu to the Tapajos. Most wisely she has confined the Belen zoo to the animals of the lower Amazon valley, and in consequence I know of no better local zoological gardens. She has an invaluable collection of birds and mammals of the region; and it was a privilege to meet her and talk with her.

We also met Professor Farrabee, of the University of Pennsylvania, the ethnologist. He had just finished a very difficult and important trip, from Manaos by the Rio Branco to the highlands of Guiana, across them on foot, and down to the seacoast of British Guiana. He is an admirable representative of the men who are now opening South America to scientific knowledge.

On May 7 we bade good-by to our kind Brazilian friends and sailed northward for Barbados and New York.

Zoologically the trip had been a thorough success. Cherrie and Miller had collected over twenty-five hundred birds, about five hundred mammals, and a few reptiles, batrachians, and fishes. Many of them were new to science; for much of the region traversed had never previously been worked by any scientific collector.

Of course, the most important work we did was the geographic work, the exploration of the unknown river, undertaken at the suggestion of the Brazilian Government, and in conjunction with its representatives. No piece of work of this kind is ever achieved save as it is based on long continued previous work. As I have before said, what we did was to put the cap on the pyramid that had been built by Colonel Rondon and his a.s.sociates of the Telegraphic Commission during the six previous years. It was their scientific exploration of the chapadao, their mapping the basin of the Juruena, and their descent of the Gy- Parana that rendered it possible for us to solve the mystery of the River of Doubt.

The work of the commission, much the greatest work of the kind ever done in South America, is one of the many, many achievements which the republican government of Brazil has to its credit. Brazil has been blessed beyond the average of her Spanish-American sisters because she won her way to republicanism by evolution rather than revolution. They plunged into the extremely difficult experiment of democratic, of popular, self-government, after enduring the atrophy of every quality of self-control, self-reliance, and initiative throughout three withering centuries of existence under the worst and most foolish form of colonial government, both from the civil and the religious standpoint, that has ever existed. The marvel is not that some of them failed, but that some of them have eventually succeeded in such striking fashion. Brazil, on the contrary, when she achieved independence, first exercised it under the form of an authoritative empire, then under the form of a liberal empire. When the republic came, the people were reasonably ripe for it. The great progress of Brazil--and it has been an astonishing progress--has been made under the republic. I could give innumerable examples and ill.u.s.trations of this. The change that has converted Rio Janeiro from a picturesque pest-hole into a singularly beautiful, healthy, clean, and efficient modern great city is one of these. Another is the work of the Telegraphic Commission.

We put upon the map a river some fifteen hundred kilometres in length, of which the upper course was not merely utterly unknown to, but unguessed at by, anybody; while the lower course, although known for years to a few rubbermen, was utterly unknown to cartographers. It is the chief affluent of the Madeira, which is itself the chief affluent of the Amazon.

The source of this river is between the 12th and 13th parallels of lat.i.tude south and the 59th and 60th degrees of longitude west from Greenwich. We embarked on it at about lat.i.tude 12 degrees 1 minute south, and about longitude 60 degrees 15 minutes west. After that its entire course lay between the 60th and 61st degrees of longitude, approaching the latter most closely about lat.i.tude 8 degrees 15 minutes. The first rapids we encountered were in lat.i.tude 11 degrees 44 minutes, and in uninterrupted succession they continued for about a degree, without a day's complete journey between any two of them. At 11 degrees 23 minutes the Rio Kermit entered from the left, at 11 degrees 22 minutes the Rio Marciano Avila from the right, at 11 degrees 18 minutes the Taunay from the left, at 10 degrees 58 minutes the Cardozo from the right. In 10 degrees 24 minutes we encountered the first rubbermen. The Rio Branco entered from the left at 9 degrees 38 minutes. Our camp at 8 degrees 49 minutes was nearly on the boundary between Matto Grosso and Amazonas. The confluence with the Aripuanan, which joined from the right, took place at 7 degrees 34 minutes. The entrance into the Madeira was at about 5 degrees 20 minutes (this point we did not determine by observation, as it is already on the maps). The stream we had followed down was from the river's highest sources; we had followed its longest course.

APPENDIX A.

The Work of the Field Zoologist and Field Geographer in South America

Portions of South America are now entering on a career of great social and industrial development. Much remains to be known, so far as the outside world is concerned, of the social and industrial condition in the long-settled interior regions. More remains to be done, in the way of pioneer exploring and of scientific work, in the great stretches of virgin wilderness. The only two other continents where such work, of like volume and value, remains to be done are Africa and Asia; and neither Africa nor Asia offers a more inviting field for the best kind of field worker in geographical exploration and in zoological, geological, and paleontological investigation. The explorer is merely the most adventurous kind of field geographer; and there are two or three points worth keeping in mind in dealing with the South American work of the field geographer and field zoologist.

Roughly, the travellers who now visit (like those who for the past century have visited) South America come in three categories-- although, of course, these categories are not divided by hard-and-fast lines.

First, there are the travellers who skirt the continent in comfortable steamers, going from one great seaport to another, and occasionally taking a short railway journey to some big interior city not too far from the coast. This is a trip well worth taking by all intelligent men and women who can afford it; and it is being taken by such men and women with increasing frequency. It entails no more difficulty than a similar trip to the Mediterranean--than such a trip which to a learned and broad-minded observer offers the same chance for acquiring knowledge and, if he is himself gifted with wisdom, the same chance of imparting his knowledge to others that is offered by a trip of similar length through the larger cities of Europe or the United States.

Probably the best instance of the excellent use to which such an observer can put his experience is afforded by the volume of Mr.

Bryce. Of course, such a trip represents travelling of essentially the same kind as travelling by railroad from Atlanta to Calgary or from Madrid to Moscow.

Next there are the travellers who visit the long-settled districts and colonial cities of the interior, travelling over land or river highways which have been traversed for centuries but which are still primitive as regards the inns and the modes of conveyance. Such travelling is difficult in the sense that travelling in parts of Spain or southern Italy or the Balkan states is difficult. Men and women who have a taste for travel in out-of-way places and who, therefore, do not mind slight discomforts and inconveniences have the chance themselves to enjoy, and to make others profit by, travels of this kind in South America. In economic, social, and political matters the studies and observations of these travellers are essential in order to supplement, and sometimes to correct, those of travellers of the first category; for it is not safe to generalize overmuch about any country merely from a visit to its capital or its chief seaport. These travellers of the second category can give us most interesting and valuable information about quaint little belated cities; about backward country folk, kindly or the reverse, who show a mixture of the ideas of savagery with the ideas of an ancient peasantry; and about rough old highways of travel which in comfort do not differ much from those of mediaeval Europe. The travellers who go up or down the highway rivers that have been travelled for from one to four hundred years--rivers like the Paraguay and Parana, the Amazon, the Tapajos, the Madeira, the lower Orinoco--come in this category. They can add little to our geographical knowledge; but if they are competent zoologists or archaeologists, especially if they live or sojourn long in a locality, their work may be invaluable from the scientific standpoint. The work of the archaeologists among the immeasurably ancient ruins of the low-land forests and the Andean plateaux is of this kind. What Aga.s.siz did for the fishes of the Amazon and what Hudson did for the birds of the Argentine are other instances of the work that can thus be done. Burton's writings on the interior of Brazil offer an excellent instance of the value of a sojourn or trip of this type, even without any especial scientific object.

Of course travellers of this kind need to remember that their experiences in themselves do not qualify them to speak as wilderness explorers. Exactly as a good archaeologist may not be competent to speak of current social or political problems, so a man who has done capital work as a tourist observer in little-visited cities and along remote highways must beware of regarding himself as being thereby rendered fit for genuine wilderness work or competent to pa.s.s judgment on the men who do such work. To cross the Andes on mule-back along the regular routes is a feat comparable to the feats of the energetic tourists who by thousands traverse the mule trails in out-of-the-way nooks of Switzerland. An ordinary trip on the highway portions of the Amazon, Paraguay, or Orinoco in itself no more qualifies a man to speak of or to take part in exploring unknown South American rivers than a trip on the lower Saint Lawrence qualifies a man to regard himself as an expert in a canoe voyage across Labrador or the Barren Grounds west of Hudson Bay.

A hundred years ago, even seventy or eighty years ago, before the age of steamboats and railroads, it was more difficult than at present to define the limits between this cla.s.s and the next; and, moreover, in defining these limits I emphatically disclaim any intention of thereby attempting to establish a single standard of value for books of travel. Darwin's "Voyage of the Beagle" is to me the best book of the kind ever written; it is one of those cla.s.sics which decline to go into artificial categories, and which stand by themselves; and yet Darwin, with his usual modesty, spoke of it as in effect a yachting voyage. Humboldt's work had a profound effect on the thought of the civilized world; his trip was one of adventure and danger; and yet it can hardly be called exploration proper. He visited places which had been settled and inhabited for centuries and traversed places which had been travelled by civilized men for years before he followed in their footsteps. But these places were in Spanish colonies, and access to them had been forbidden by the mischievous and intolerant tyranny-- ecclesiastical, political, and economic--which then rendered Spain the most backward of European nations; and Humboldt was the first scientific man of intellectual independence who had permission to visit them. To this day many of his scientific observations are of real value. Bates came to the Amazon just before the era of Amazonian steamboats. He never went off the native routes of ordinary travel.

But he was a devoted and able naturalist. He lived an exceedingly isolated, primitive, and laborious life for eleven years. Now, half a century after it was written, his "Naturalist on the Amazon" is as interesting and valuable as it ever was, and no book since written has in any way supplanted it.

Travel of the third category includes the work of the true wilderness explorers who add to our sum of geographical knowledge and of the scientific men who, following their several bents, also work in the untrodden wilds. Colonel Rondon and his a.s.sociates have done much in the geographical exploration of unknown country, and Cherrie and Miller have penetrated and lived for months and years in the wastes, on their own resources, as incidents to their mammalogical and ornithological work. Professor Farrabee, the anthropologist, is a capital example of the man who does this hard and valuable type of work.

An immense amount of this true wilderness work, geographical and zoological, remains to be done in South America. It can be accomplished with reasonable thoroughness only by the efforts of very many different workers, each in his own special field. It is desirable that here and there a part of the work should be done in outline by such a geographic and zoological reconnaissance as ours; we would, for example, be very grateful for such work in portions of the interior of the Guianas, on the headwaters of the Xingu, and here and there along the eastern base of the Andes.

But as a rule the work must be specialized; and in its final shape it must be specialized everywhere. The first geographical explorers of the untrodden wilderness, the first wanderers who penetrate the wastes where they are confronted with starvation, disease, and danger and death in every from, cannot take with them the elaborate equipment necessary in order to do the thorough scientific work demanded by modern scientific requirements. This is true even of exploration done along the courses of unknown rivers; it is more true of the exploration, which must in South America become increasingly necessary, done across country, away from the rivers.

The scientific work proper of these early explorers must be of a somewhat preliminary nature; in other words the most difficult and therefore ordinarily the most important pieces of first-hand exploration are precisely those where the scientific work of the accompanying cartographer, geologist, botanist, and zoologist must be furthest removed from finality. The zoologist who works to most advantage in the wilderness must take his time, and therefore he must normally follow in the footsteps of, and not accompany, the first explorers.

The man who wishes to do the best scientific work in the wilderness must not try to combine incompatible types of work nor to cover too much ground in too short a time.

There is no better example of the kind of zoologist who does first- cla.s.s field-work in the wilderness than John D. Haseman, who spent from 1907 to 1910 in painstaking and thorough scientific investigation over a large extent of South American territory hitherto only partially known or quite unexplored. Haseman's primary object was to study the characteristics and distribution of South American fishes, but as a matter of fact he studied at first hand many other more or less kindred subjects, as may be seen in his remarks on the Indians and in his excellent pamphlet on "Some Factors of Geographical Distribution in South America."

Haseman made his long journey with a very slender equipment, his extraordinarily successful field-work being due to his bodily health and vigor and his resourcefulness, self-reliance, and resolution. His writings are rendered valuable by his accuracy and common sense. The need of the former of these two attributes will be appreciated by whoever has studied the really scandalous fictions which have been published as genuine by some modern "explorers" and adventurers in South America; and the need of the latter by whoever has studied some of the wild theories propounded in the name of science concerning the history of life on the South American continent. There is, however, one serious criticism to be made on Haseman: the extreme obscurity of his style--an obscurity mixed with occasional bits of scientific pedantry, which makes it difficult to tell whether or not on some points his thought is obscure also. Modern scientists, like modern historians and, above all, scientific and historical educators, should ever keep in mind that clearness of speech and writing is essential to clearness of thought and that a simple, clear, and, if possible, vivid style is vital to the production of the best work in either science or history. Darwin and Huxley are cla.s.sics, and they would not have been if they had not written good English. The thought is essential, but ability to give it clear expression is only less essential. Ability to write well, if the writer has nothing to write about, ent.i.tles him to mere derision. But the greatest thought is robbed of an immense proportion of its value if expressed in a mean or obscure manner. Mr. Haseman has such excellent thought that it is a pity to make it a work of irritating labor to find out just what the thought is. Surely, if he will take as much pains with his writing as he has with the far more difficult business of exploring and collecting, he will become able to express his thought clearly and forcefully. At least he can, if he chooses, go over his sentences until he is reasonably sure that they can be pa.r.s.ed. He can take pains to see that his whole thought is expressed, instead of leaving vacancies which must be filled by the puzzled and groping reader. His own views and his quotations from the views of others about the static and dynamic theories of distribution are examples of an important principle so imperfectly expressed as to make us doubtful whether it is perfectly apprehended by the writer. He can avoid the use of those pedantic terms which are really nothing but offensive and, fortunately, ephemeral scientific slang. There has been, for instance, a recent vogue for the extensive misuse, usually tautological misuse, of the word "complexus"--an excellent word if used rarely and for definite purposes. Mr. Haseman drags it in continually when its use is either pointless and redundant or else serves purely to darken wisdom.

He speaks of the "Antillean complex" when he means the Antilles, of the "organic complex" instead of the characteristic or bodily characteristics of an animal or species, and of the "environmental complex" when he means nothing whatever but the environment. In short, Mr. Haseman and those whose bad example he in this instance follows use "complexus" in much the same spirit as that displayed by the famous old lady who derived religious--instead of scientific-- consolation from the use of "the blessed word Mesopotamia."

The reason that it is worth while to enter this protest against Mr.

Haseman's style is because his work is of such real and marked value.

The pamphlet on the distribution of South American species shows that to exceptional ability as a field worker he adds a rare power to draw, with both caution and originality, the necessary general conclusions from the results of his own observations and from the recorded studies of other men; and there is nothing more needed at the present moment among our scientific men than the development of a school of men who, while industrious and minute observers and collectors and cautious generalizers, yet do not permit the faculty of wise generalization to be atrophied by excessive devotion to labyrinthine detail.

Haseman upholds with strong reasoning the theory that since the appearance of all but the lowest forms of life on this globe there have always been three great continental ma.s.ses, sometimes solid sometimes broken, extending southward from the northern hemisphere, and from time to time connected in the north, but not in the middle regions or the south since the carboniferous epoch. He holds that life has been intermittently distributed southward along these continental ma.s.ses when there were no breaks in their southward connection, and intermittently exchanged between them when they were connected in the north; and he also upholds the view that from a common ancestral form the same species has been often developed in entirely disconnected localities when in these localities the conditions of environment were the same.

The opposite view is that there have been frequent connections between the great land ma.s.ses, alike in the tropics, in the south temperate zone, and in the Antarctic region. The upholders of this theory base it almost exclusively on the distribution of living and fossil forms of life; that is, it is based almost exclusively on biological and not geological considerations. Unquestionably, the distribution of many forms of life, past and present, offers problems which with our present paleontological knowledge we are wholly unable to solve. If we consider only the biological facts concerning some one group of animals it is not only easy but inevitable to conclude that its distribution must be accounted for by the existence of some former direct land bridge extending, for instance, between Patagonia and Australia, or between Brazil and South Africa, or between the West Indies and the Mediterranean, or between a part of the Andean region and northeastern Asia. The trouble is that as more groups of animals are studied from the standpoint of this hypothesis the number of such land bridges demanded to account for the existing facts of animal distribution is constantly and indefinitely extended. A recent book by one of the most learned advocates of this hypothesis calls for at least ten such land bridges between South America and all the other continents, present and past, of the world since a period geologically not very remote. These land bridges, moreover, must, many of them, have been literally bridges; long, narrow tongues of land thrust in every direction across the broad oceans. According to this view the continental land ma.s.ses have been in a fairly fluid condition of instability. By parity of reasoning, the land bridges could be made a hundred instead of merely ten in number. The facts of distribution are in many cases inexplicable with our present knowledge; yet if the existence of widely separated but closely allied forms is habitually to be explained in accordance with the views of the extremists of this school we could, from the exclusive study of certain groups of animals, conclude that at different periods the United States and almost every other portion of the earth were connected by land and severed from all other regions by water--and, from the study of certain other groups of animals, arrive at directly opposite and incompatible conclusions.

The most brilliant and unsafe exponent of this school was Ameghino, who possessed and abused two gifts, both essential to the highest type of scientist, and both mischievous unless this scientist possess a rare and accurate habit of thought joined to industry and mastery of detail:--namely, the gift of clear and interesting writing, and the gift of generalization. Ameghino rendered marked services to paleontology. But he generalized with complete recklessness from the slenderest data; and even these data he often completely misunderstood or misinterpreted. His favorite thesis included the origin of mammalian life and of man himself in southernmost South America, with, as incidents, the belief that the mammalian-bearing strata of South America were of much greater age than the strata with corresponding remains elsewhere; that in South America various species and genera of men existed in tertiary times, some of them at least as advanced as fairly well advanced modern savages; that there existed various land bridges between South America and other southern continents, including Africa; and that the ancestral types of modern mammals and of man himself wandered across one of these bridges to the old world, and that thence their remote descendants, after ages of time, returned to the new. In addition to valuable investigations of fossil-bearing beds in the Argentine, he made some excellent general suggestions, such as that the pithecoid apes, like the baboons, do not stand in the line of man's ancestral stem but represent a divergence from it away from humanity and toward a retrogressive b.e.s.t.i.a.lization. But of his main theses he proves none, and what evidence we have tells against them.

At the Museum of La Plata I found that the authorities were practically a unit in regarding his remains of tertiary men and proto- men as being either the remains of tertiary American monkeys or of American Indians from strata that were long post-tertiary. The extraordinary discovery, due to that eminent scientist and public servant Doctor Moreno, of the remains of man a.s.sociated with the remains of the great extinct South American fauna, of the mylodon, of a giant ungulate, of a huge cat like the lion, and of an extraordinary aberrant horse (of a wholly different genus from the modern horse) conclusively shows that in its later stages the South American fauna consisted largely of types that elsewhere had already disappeared and that these types persisted into what was geologically a very recent period only some tens of thousands of years ago, when savage man of practically a modern type had already appeared in South America. The evidence we have, so far as it goes, tends to show that the South American fauna always has been more archaic in type than the arctogeal fauna of the same chronological level.

To loose generalizations, and to elaborate misinterpretations of paleontological records, the kind of work done by Mr. Haseman furnishes an invaluable antis...o...b..tic. To my mind, he has established a stronger presumption in favor of the theory he champions than has been established in favor of the theories of any of the learned and able scientific men from whose conclusions he dissents. Further research, careful, accurate, and long extended, can alone enable us to decide definitely in the matter; and this research, to be effective, must be undertaken by many men, each of whom shall in large measure possess Mr. Haseman's exceptional power of laborious work both in the field and in the study, his insight and accuracy of observation, and his determination to follow truth with inflexible rect.i.tude wherever it may lead--one of the greatest among the many great qualities which lifted Huxley and Darwin above their fellows.

APPENDIX B.

The Outfit for Travelling in the South American Wilderness

South America includes so many different kinds of country that it is impossible to devise a scheme of equipment which shall suit all. A hunting-trip in the panta.n.a.ls, in the swamp country of the upper Paraguay, offers a simple problem. An exploring trip through an unknown tropical forest region, even if the work is chiefly done by river, offers a very difficult problem. All that I can pretend to do is to give a few hints as the results of our own experience.

For bedding there should be a hammock, mosquito-net, and light blanket. These can be obtained in Brazil. For tent a light fly is ample; ours were brought with us from New York. In exploring only the open fly should be taken; but on trips where weight of luggage is no objection, there can be walls to the tent and even a canvas floor- cloth. Camp-chairs and a camp table should be brought--any good outfitter in the United States will supply them--and not thrown away until it becomes imperative to cut everything down. On a river trip, first-cla.s.s pulleys and ropes--preferably steel, and at any rate very strong--should be taken. Unless the difficulties of transportation are insuperable, canvas-and-cement canoes, such as can be obtained from various firms in Canada and the United States, should by all means be taken. They are incomparably superior to the dugouts. But on different rivers wholly different canoes, of wholly different sizes, will be needed; on some steam or electric launches may be used; it is not possible to lay down a general rule.
