Ever since America was discovered, the question about it which has excited the most general interest has been, Whence came its inhabitants? The inquiry, Who are the American Indians? has been the theme of many a ponderous folio and labored dissertation, with answers nearly as various as the number of debaters.
Few or none of them have reflected on the unphilosophical character of the inquiry as thus crudely put. Take a precisely analogous question, and this will be apparent—Whence came the African Negroes? All will reply—From Africa, of course. Originally? Yes, originally; they constitute the African or Negro sub-species of Man.
The answer in the case of the American Indians is entirely parallel—their origin is American; the racial type was created and fixed on the American continent; they constitute as true and distinct a sub-species as do the African or the White Race.
Each of the great continental areas moulded the plastic, primitive man into a conformation of body and mind peculiar to itself, in some special harmony with its own geographic features, thus producing a race or sub-species, subtly correlated in a thousand ways to its environment, but never forfeiting its claim to humanity, never failing in its parallel and progressive development with all other varieties of the species.
America was no exception to this rule, and it is time to dismiss as trivial all attempts to connect the American race genealogically with any other, or to trace the typical culture of this continent to the historic forms of the Old World. My early studies inclined me to these opinions, and they have been constantly strengthened by further research. Yet they are not popularly accepted; the very latest writer of competence on the pre-history of America says, “It is now generally held that the earliest population (of the continent) was intruded upon by other races, coming either from Asia or from the Pacific Islands, from whom were descended the various tribes which have occupied the soil down to the present time.”[1]
It is true that this opinion is that generally held, and for this reason I have selected for reprinting some articles intended to show that it is utterly fallacious—devoid of any respectable foundation.
The first two papers treat of the archæologic material, and its value for ascertaining the pre-historic life of the American race; the third, on its pretended affinities to Asiatic peoples. These are followed by two papers respectively on the Toltecs and Mound-Builders, setting aright, I hope, the position of these semi-mythical shapes in the culture-history of North America, maintaining that for neither do we have to call in as explanation migrations from Asia, Europe, Oceanica or Africa, as has so often been attempted.
Early in this century the doubt was expressed by Alexander von Humboldt[3] whether it is philosophical to inquire into the origin of any of the human races or sub-species. Although he expressed this doubt with particular reference to the American race, I believe I am right in assuming that the hesitancy he felt in pushing inquiry so far should now diminish in view of new methods of research and a wider range of observations. We may not, in fact we shall not, be able to trace the American or any other sub-species directly back to its origin in place or time; but by reviewing all the data which have been offered in solution of such a problem, we may perceptibly narrow the question, and also estimate the relative value of the means proposed. It is to such a review, applied to the American race, that I now invite your attention.
The data upon which theories of the antiquity, the genealogy and the affinities of this race have been constructed are varied. For convenience of treatment I shall class them under six heads. They are:
I. Legendary, including the traditions of the native tribes and their own statements of their history.
II. Monumental, where we have to do with those structures whose age or character seems to throw light on the question.
III. Industrial, under which heading we may inquire as to the origin of both the useful and the decorative arts in the New World.
IV. Linguistic, broaching the immense and important questions as to the diversity and affinities of languages.
V. Physical, which takes into consideration the anatomic and morphologic peculiarities of the American race; and finally,
VI. Geologic, where its position in the geologic horizons is to be determined, and the influence upon it of the physical geography of the continent.
Legendary. Turning to the first of these, the legendary data, I confess to a feeling of surprise that learned scholars should still hold to the opinion that the native tribes, even some of the most savage of them, retain to this day traditions which they had brought from their supposed Asiatic homes. Thus the missionaries, Bishop Henry Faraud and the Abbé Emile Petitot, both entirely familiar with the Cree and the Athapaskan languages and lore, insist that the myths and legends of these tribes bear such strong resemblances to the Semitic traditions that both must have had a common origin.[4] No one can deny the resemblance; but the scientific student of mythology discovers such identities too frequently, and at points too remote, to ask any other explanation for them than the common nature of the human mind.
The question has been often raised how long a savage tribe, ignorant of writing, is likely to retain the memory of past deeds. From a great many examples in America and elsewhere, it is probable that the lapse of five generations, or say two centuries, completely obliterates all recollection of historic occurrences. Of course, there are certain events of continuous influence which may be retained in memory longer—for example, the federation of prominent tribes; and perhaps a genealogy may run back farther. My friend, Dr. Franz Boas, informs me that some tribes on Vancouver’s Island pretend to preserve their genealogies for twelve or fifteen generations back; but he adds that the remoter names are clearly of mythical purport.
It appears obvious that all efforts to establish a pre-historic chronology by means of the legends of savage tribes, are and must be vain.
The case is not much better with those semi-civilized American nations, the Mayas and Nahuas, who possessed a partially phonetic alphabet, or with the Quichuas, who preserved their records by the ingenious device of the quipu. Manco Capac, the alleged founder of the Peruvian state, floats before us as a vague and mythical figure, though he is placed in time not earlier than the date when Leif, the son of Erik, anchored his war-ship on the Nova Scotian coast.[5] Historians are agreed that the long lists of Incas in the pages of Montesinos, extending about two thousand years anterior to the Conquest, are spurious, due to the imagination or the easy credulity of that writer.
The annals of Mexico fare no better before the fire of criticism. It is extremely doubtful that their earliest reminiscences refer to any event outside the narrow valley parcelled out between the petty states of Tenochtitlan, Tezcuco, and Tlacopan.[6] The only fact that bears out the long and mysterious journey from the land of the Seven Caves, Chicomoztoc, in the distant northwest, by the great water, is that the learned and indefatigable Buschmann has conclusively shown that the four languages of Sonora and all the dialects of the Shoshonian family reveal marks of continued and deep impressions of the Nahuatl tongue.[7] But the chronicles of Mexico proper contain no fixed date prior to that of the founding of the city of Tenochtitlan, in the year 1325 of our era.
I am aware that there are still some writers who maintain that both the Mexican and the Maya astronomic cycles assume a commencement for their records centuries, even thousands of years, before the beginning of our era. These opinions, however, have not obtained the assent of other students. We are too ignorant both of the astronomy and the methods of writing of these nations to admit such claims; and the facts advanced are capable of quite other interpretation.
It is, on the whole, rare for the American tribes to declare themselves autochthonous. The Mayas, on the peninsula of Yucatan, stated that their earliest ancestors came there from beyond the seas, some from the far east, others from the west. So the Toltecs, under Quetzalcoatl, were fabled to have entered Mexico from beyond the Eastern Ocean. The Creeks and Choctaws pointed to the west, the Algonkins generally to the east, as their primal home.[8] These legends are chiefly mythical, not much truer than those of other tribes who claimed to have climbed up from some under-world. Sifting them all, we shall find in them little to enlighten us as to the pre-historic chronology of the tribes, though they may furnish interesting vistas in comparative mythology.
That in which we may expect the legends of tribes to be of most avail is their later history, the record of their wars, migrations and social development within a few generations. The spirit of the uncivilized man is, however, very careless of the past. We have means of testing the exactness of such traditions in some instances, and the result is rarely such as to inspire confidence in verbal records. Those of you who were present at the last meeting will remember how diversely two able students of Iroquois tradition estimated its value. Even when remarkable events are not forgotten, the dates of their occurrence are generally vague. The inference, therefore, is that very few data, dependent on legendary evidence alone, can be accepted.
Monumental. When we turn to the monumental data, to the architecture and structural relics of the ancient Americans, we naturally think first of the imposing stone-built fortresses of Peru, the massive pyramids and temples of Yucatan and Mexico, and the vast brick-piles of the Pueblo Indians.
It is doubtful if any of these notable monuments supply pre-historic dates of excessive antiquity. The pueblos, both those now occupied and the vastly greater number whose ruins lie scattered over the valleys and mesas of New Mexico and Arizona, were constructed by the ancestors of the tribes who still inhabit that region, and this at no distant day. Though we cannot assign exact dates to the development of this peculiar civilization, there are abundant reasons, drawn from language, physical geography and the character of the architecture, to include all these structures within the period since the commencement of our era.[9]
There is every reason to suppose that the same is true of all the stone and brick edifices of Mexico and Central America. The majority of them were occupied at the period of the Conquest; others were in process of building; and of others the record of the date of their construction was clearly in memory and was not distant. Thus, the famous temple of Huitzilopochtli at Tenochtitlan, and the spacious palace—or, if you prefer the word, “communal house”—of the ruler of Tezcuco, had been completed within the lifetime of many who met the Spaniards. To be sure, even then there were once famous cities fallen to ruin and sunk to oblivion in the tropical forests. Such was Palenque, which could not have failed to attract the attention of Cortes had it been inhabited. Such also was T’Ho, on the site of the present city of Mérida, Yucatan, where the earliest explorers found lofty stone mounds and temples covered with a forest as heavy as the primitive growth around it.[10] But tradition and the present condition of such of these old cities as have been examined, unite in the probability that they do not antedate the Conquest more than a few centuries.
In the opinion of some observers, the enigmatical ruins on the plain of Tiahuanaco, a few leagues from the shore of Lake Titicaca, in Peru, carry us far, very far, beyond any such modern date. “Even the memory of their builders,” says one of the more recent visitors to these marvellous relics, General Bartolomé Mitre, “even their memory was lost thousands of years before the discovery of America.”[11]
Such a statement is neither more nor less than a confession of ignorance. We have not discovered the period nor the people concerned in the ruins of Tiahuanaco. It must be remembered that they are not the remains of a populous city, but merely the foundations and beginnings of some vast religious edifice which was left incomplete, probably owing to the death of the projector or to unforeseen difficulties. If this is borne in mind, much of the obscurity about the origin, the purpose and the position of these structures will be removed. They do not justify a claim to an age of thousands of years before the Conquest; hundreds will suffice. Nor is it necessary to assent to the opinion advanced by General Mitre, and supported by some other archæologists, that the most ancient monuments in America are those of most perfect construction, and, therefore, that in this continent there has been, in civilization, not progress but failure, not advance but retrogression.
The uncertainty which rests over the age of the structures at Tiahuanaco is scarcely greater than that which still shrouds the origin of the mounds and earthworks of the Ohio and Upper Mississippi valleys. Yet I venture to say that the opinion is steadily gaining ground that these interesting memorials of vanished nations are not older than the mediæval period of European history. The condition of the arts which they reveal indicates a date that we must place among the more recent in American chronology. The simple fact that tobacco and maize were cultivated plants is evidence enough for this.[12]
There is, however, a class of monuments of much greater antiquity than any I have mentioned. These are the artificial shell-heaps which are found along the shores of both oceans and of many rivers in both North and South America. They correspond to the kitchen-middens of European archæology.
In several parts of the continent they have been examined by competent observers and the question of their date approximately ascertained. I need not say this differs widely, for these refuse heaps of ancient villages or stations were of course begun at wide intervals.
Long ago I called attention to the singular size and antiquity of those I found in Florida and along the Tennessee River;[13] and the later researches of Professor Jeffries Wyman would, in his opinion, measure the age of some of the former by tens of thousands of years.[14]
Further to the south, in Costa Rica, Dr. Earl Flint has examined the extensive artificial shell deposits which are found along the shores of that republic. They are many feet in height, covered by a dense forest of primeval appearance, and are undoubtedly of human origin.
In Brazil such shell-heaps are called sambaquis, and they are of frequent occurrence along the bays and inlets of the coast. Some of them are of extraordinary dimensions, rising occasionally to more than a hundred feet in height. The lower layers have been consolidated into a firm, stony breccia of shells and bones, while the surface stratum, from six to ten feet thick, is composed of sand and vegetable loam supporting a growth of the largest trees. Yet even the lowest layers of this breccia, or shell-conglomerate, yield tokens of human industry, as stone axes, flint arrow-heads, chisels, and fragments of very rude pottery, as well as human bones, sometimes split to extract the marrow. The shells are by no means all of modern type. Many are of species now wholly extinct, or extinct in the locality. This fact alone carries us back to an antiquity which probably should be counted by thousands of years before our era.
At that remote period not only did a fishing and hunting race dwell along the Brazilian coast, but this race was fairly advanced on the path to culture; it was acquainted with pottery, with compound implements, and with the polishing of stone. We further know that this race was not that which occupied the land when the whites discovered it; for the human skulls disinterred from the sambaquis are, craniologically, almost diametrically opposite those of the Botocudos and the Tupis. Yet if we can trust the researches of Dr. Lund in the caverns of Brazil, the oldest skulls in these deposits, found in immediate connection with the bones of extinct mammalia, belonged to the ancestors of these tribes. Markedly dolichocephalic, they present an entire contrast to the brachycephalic type from the sambaquis.[15]
This class of monuments, therefore, supply us data which prove man’s existence in America in what some call the “diluvial,” others the “quaternary,” and others again the “pleistocene” epoch—that characterized by the presence of some extinct species.
Industrial. Let us now turn to the industrial activity of the American race, and see whether it will furnish us other data concerning the pre-historic life of the New World. We may reasonably look in this direction for aid, since it is now universally conceded that at no time did man spring into being fully armed and equipped for the struggle for existence, but everywhere followed the same path of painful effort from absolute ignorance and utter feebleness to knowledge and power. At first, his only weapons or tools were such as he possessed in common with the anthropoid apes: to wit, an unshapen stone and a broken stick. Little by little, he learned to fit his stone to his hand and to chip it to an edge, and with this he could sharpen the end of his stick, thus providing himself with a spear and an axe.
It was long before he learned to shape and adjust the stone to the end of the stick, and to hurl this by means of a cord attached to a second and elastic stick—in other words, a bow; still longer before he discovered the art of fashioning clay into vessels and of polishing and boring stones. These simple arts are landmarks in the progress of the race: the latter divides the history of culture into the palæolithic or rough stone period, and the neolithic or polished stone period; while the shaping of a stone for attachment to a handle or shaft marks the difference between the epoch of compound implements and the earlier epoch of simple implements, both included in the older or palæolithic age.[16] With these principles as guides, we may ask how far back on this scale do the industrial relics in America carry us?
I have spoken of the great antiquity of some of the American shell-heaps, how they carry us back to the diluvial epoch, and that of numerous extinct species. Yet it is generally true that in the oldest hitherto examined in Brazil, Guiana, Costa Rica and Florida, fragments of pottery, of polished stone, and compound implements, occur even in the lowest strata.[17] Venerable though they are, they supply no date older than what in Europe we should call the neolithic period. The arrow-heads which have been exhumed from the loess of the ancient lake-beds of Nebraska, the net-sinkers and celts which have been recovered from the auriferous gravels of California, prove by their form and finish that the tribes who fashioned them had already taken long strides beyond the culture of the earlier palæolithic age. The same is true, though in a less degree, of the chipped stones and bones which Ameghino exhumed from the lacrustine deposits of the Pampas, although he proves that these relics were the products of tribes contemporary with the extinct glyptodon and mylodon, as well as the fossil horse and dog. In the very oldest station which he examined, there appears to have been found a quartz arrow-head; yet he argues that this station dated from the pliocene division of the tertiary, long anterior to the austral glacial epoch.[18] This leaves another such open conflict between geology and the history of culture, as Professor Rau has already pointed out as existing in Californian archæology.
There is, however, one station in America which has furnished an ample line of specimens, and among them not one, so far as I know, indicating a knowledge of compound implements. This is that of the “Trenton gravels,” New Jersey. There we appear to be in face of a stage of culture as primitive as that of the stations of Chelles and St. Acheul in France, absolutely without pottery, without polished stone, without compound implements.[19]
Assuming that these post-glacial gravels about Trenton supply one of the earliest authentic starting points in the history of culture on this continent, the later developments of industry will furnish a number of other data. This first date was long before the extinction of the native American horse, the elephant, the mammoth, and other animals important to early man. There is nothing unlikely therefore in the reported discoveries of his pointed flints or his bones in place along with the remains of these quadrupeds.
Not only the form but the material of implements supplies us data. If man in his earliest stage was, as some maintain, quite migratory, it is certain that he did not carry his stone implements with him, nor did he obtain by barter or capture those of other tribes. All the oldest implements are manufactured from the rocks of the locality. When, therefore, we find a weapon of a material not obtainable in the vicinity, we have a sure indication that it belongs to a period of development considerably later than the earliest. When the obsidian of the Yellowstone Park is found in Ohio, when the black slate of Vancouver’s Island is exhumed in Delaware, it is obvious we must assume for such extensive transits a very noticeable æsthetic and commercial development.
I can but touch in the lightest manner on the data offered by the vast realm of industrial activity. The return it offers is abundant, but the harvesting delicate. In the dissemination of certain kinds of arts, certain inventions, certain decorative designs and æsthetic conceptions from one tribe to another, we have a most valuable means of tracing the pre-historic intercourse of nations: but we must sedulously discriminate such borrowing from the synchronous and similar development of independent culture under like conditions.
In one department of industry we shall be largely free from this danger, that is, in the extension of agriculture. One of America’s ablest ethnologists, Dr. Charles Pickering, as the result of a lifetime devoted to his science, finally settled upon the extension of cultivated plants as the safest guide in the labyrinth of pre-historic migrations. Its value is easily seen in America when we reflect that the two tropical plants, maize and tobacco, extended their area in most remote times from their limited local habitat about the Isthmus of Tehuantepec to the north as far as the St. Lawrence river and to the south quite to the Archipelago of Chiloe. Their presence is easily traced by the stone or earthen-ware implements required for their use. How many ages it must have required for these plants to have thus extended their domain, amid hostile and savage tribes, through five thousand miles of space! The squash, the bean, the potato and the mandioca, are native food-plants offering in a less degree similar material for tracing ancient commerce and migration. Humboldt and others have claimed as much for the banana (Musa paradisiaca), but the recent researches of Dr. Karl von den Steinen have removed that valued fruit from the list of native American plants. Both species of banana (M. paradisiaca and M. sapientium) were undoubtedly introduced into the New World after the discovery.[20] Indeed, summing up the reply to an inquiry which has often been addressed to the industrial evolution of the indigenes of our continent, I should say that they did not borrow a single art or invention nor a single cultivated plant from any part of the Old World previous to the arrival of Columbus. What they had was their own, developed from their own soil, the outgrowth of their own lives and needs.
Linguistic. This individuality of the race is still more strongly expressed in their languages. You are all aware that it is upon linguistic data almost exclusively that American ethnology has been and must be based. The study of the native tongues becomes therefore of transcendent importance in the pre-historic chronology of the Continent. But to obtain its best results, this study must be conducted in a much more thorough manner than has hitherto been the custom.
In America we are confronted with an astonishing multiplicity of linguistic stocks. They have been placed at about eighty in North and one hundred in South America. It is stated that there are that many radically diverse in elements and structure. To appreciate the vista in time that this fact opens to our thoughts, we must recognize the tenacity of life manifested by these tongues. Some of them have scores of dialects, spoken by tribes wandering over the widest areas. Take the Athapascan or Tinné, for example, found in its greatest purity amid the tribes who dwell on the Arctic sea, and along the Mackenzie river, in British America, but which is also the tongue of the Apaches who carried it almost to the valley of Mexico. The Algonkin was spoken from Hudson Bay to the Savannah river and from Newfoundland to the Rocky Mountains. The Guarani of the Rio de la Plata underlies dialects which were current as far north as Florida.
How, then, in spite of such tenacity of American languages, have so many stocks come into existence? This was the question which my predecessor in this chair last year undertook to answer. His suggestions appear to me extremely valuable, and only in one point do I widely differ from him, and that is, in the length of time required for these numerous tongues to originate, to sever into dialects and to be carried to distant regions.[21] According to the able linguist, Dr. Stoll, the difference which is presented between the Cakchiquel and Maya dialects could not have arisen in less than two thousand years;[22] and any one who has carefully compared the earliest grammars of an American tongue with its present condition will acknowledge that the changes are surprisingly few. To me the exceeding diversity of languages in America and the many dialects into which these have split, are cogent proofs of the vast antiquity of the race, an antiquity stretching back tens of thousands of years. Nothing less can explain these multitudinous forms of speech.
Underlying all these varied forms of expression, however, I think future investigation will demonstrate some curious identities of internal form, traits almost or entirely peculiar to American languages, and never quite absent from any of them.
Such was the opinion of the two earliest philosophical investigators of these tongues, P. S. Duponceau and Wilhelm von Humboldt. They called these traits polysynthesis and incorporation, and it was proposed to apply the term incorporative as a distinguishing adjective to all American languages. Of late years this opinion has been earnestly combatted by M. Lucien Adam and others; but my own studies have led me to adopt the views of the older analysts against these modern critics. I do not think that the student can compare any two stocks on the continent without being impressed with the resemblance of their expression of the relations of Being, through the incorporative plan.
Along with this identity of plan, there coëxists the utmost independence of expression. An American language is usually perfectly transparent. Nothing is easier than to reduce it to its ultimate elements, its fundamental radicals. These are few in numbers and interjectional in character. The Athapascan, the Algonkin, whose wide extension I have referred to, have been reduced to half a dozen particles or sounds expressive of the simplest conceptions.[23] Upon these, by combination, repetition, imitation and other such processes, the astonishing structure of the tongue has been erected, every portion of it displaying the mechanism of its origin. It is this transparency which renders these tongues so attractive to the philosophic student of human expression, and so valuable to him who would obtain from them the record of the progress of the nation.
A thorough study of such a language would embrace its material, its formal and its psychologic contents. Its material elements include the peculiarities of its vocabulary: for example, its numerals and the system they indicate, its words for weights and measures, for color and direction, for relations of consanguinity and affinity, for articles of use and ornament, for social and domestic conditions, and the like.
Few studies of American languages go beyond this material or lexicographic limit; but in truth these are merely the externalities of a tongue, and have nothing to do with linguistic science proper. This concerns itself with the forms of the language, with the relation of parts of speech to each other and to the sentence, and with the historical development of the grammatical categories. Beyond this, again, is the determination of the psychical character of the tribe through the forms instinctively adopted for the expression of its thoughts, and reciprocally the reaction exerted by these forms on the later intellectual growth of those who were taught them as their only means of articulate expression.
These are data of the highest value in the study of prehistoric time; but so far as America is concerned, I could name very few scholars who have pursued this promising line of research.
Physical. Much more attention has been paid to the physical than the linguistic data of the native Americans, but it may freely be said, with not more satisfactory results. This failure is partly owing to the preconceived notions which still govern the study of ethnology. Linnæus offered the cautious division of the human species into races named from the five great geographical areas it inhabited; Blumenbach pointed out that this roughly corresponded with the division into five colors, the white, black, yellow, brown and red races, occupying respectively Europe, Africa, Asia, Polynesia and America. Unfortunately, Cuvier chose to simplify this scheme, by merging the brown and red races, the Polynesian or Malayan and the American, into the yellow or Mongolian. The latest writers of the French school, and I am sorry to add various Americans, servilely follow this groundless rejection of the older scheme, and speak of Malayans and Americans alike as Mongolians or Mongoloids. Neither in language nor ethnic anatomy is there any more resemblance than between whites and Mongolians.
It is gratifying to see that the more accurate German investigators decidedly reject the blunder of Cuvier, and declare that the American race is as independent as any other of those named. Thus Dr. Paul Ehrenreich, who has lately published an admirable monograph on the Botocudos of Brazil, a tribe often quoted for its so-called “Mongoloid” aspect, declares that any such assertion must be contradicted in positive terms. Both in osteology and anatomy, in formation of the hair and shape of the skull, the differences are marked, permanent and radical.
What is true of the Botocudos is not less so of the other American tribes which are claimed to present Mongolian traits. Such assertions are based on the superficial observations of travellers, most of whom do not know the first principles of ethnic anatomy. This is sufficiently shown by the importance they attach to the oblique eye, a slight malformation of the skin of scarcely any weight.[24]
The anatomy and physiology of the various American tribes present, indeed, great diversity, and yet, beneath it all is a really remarkable fixedness of type. We observe this diversity in the shape of the skull, which may be, as among the Botocudos, strictly dolichocephalic, while the Araucanians are brachycephalic; the nasal index varies more than in the extremest members of the white race; the tint of the skin may be a dark brown with an under-color of red, or of so light a hue that a blush is easily perceptible. The beard is usually absent, but D’Orbigny visited a tribe who wore it full and long.[25] The height varies from an average of six feet four inches for adult males in Patagonia to less than five feet among the Warraus of Guiana; and so it is with all the other traits of the race. There is not one which is not subject to extensive variation.
On the other hand, these variations are not greater than can be adduced in various members of the white or black race. In spite of them all, there is a wonderful family likeness among tribes of American origin. No observer well acquainted with the type would err in taking it for another. Darwin says that the Fuegians so closely resemble the Botocudos that they seem members of the same tribe. I have seen Arawacks from Guiana who in the northwest would have passed for Sioux.
In spite of the total dissimilarity of climate and other physical surroundings, the tribes of the tropics differ no more from those near the Arctic circle than they do among themselves. This is a striking lesson how independent of environment are the essential characteristics of a race, and it is a sweeping refutation of those theories which make such characteristics dependent upon external agencies.
A still more remarkable fact has been demonstrated by Professor J. Kollmann of Bâle: to wit, that the essential physical identity of the American race is as extended in time as it is in space. This accurate student has analyzed the cranioscopic formulas of the most ancient American skulls, those from the alleged tertiary deposits of the Pampas, those from the caverns of Lagoa Santa in Brazil, that obtained from Rock Bluff, Illinois, the celebrated Calaveras skull from California, and one from Pontemelo in Buenos Ayres of geologic antiquity. His results are most interesting. These very ancient remains prove that in all important craniologic indicia the earliest Americans, those who were contemporaries of the fossil horse and other long since extinct quadrupeds, possessed the same racial character as the natives of the present day, with similar skulls and a like physiognomy.[26] We reach therefore the momentous conclusion that the American race throughout the whole continent, and from its earliest appearance in time, is and has been one, as distinct in type as any other race, and from its isolation probably the purest of all in its racial traits. This is a fact of the first order in establishing its prehistoric chronology.
Geologic. I have left the geologic data to the last, as it is these which carry us with reasonable safety to the remotest periods. No one who examines the evidence will now deny that man lived in both North and South America during and after the glacial epochs, and that he was the contemporary of many species of animals now extinct. As you are aware, the attempt has several times been made to fix the date for the final retrocession of the glaciers of North America. The estimates have varied from about 12,000 years ago up to 50,000, with a majority in favor of about 35,000 years.
There have also been various discoveries which are said to place the human species in America previous to the appearance of the glaciers. Some remains of man’s industry or of his skeleton have been reported from interglacial, others from tertiary deposits.[27] Unfortunately, these finds have not always been sufficient, or not of a character to convince the archæologist. I have before adverted to the impossibility, for instance, of an archæologist accepting the discovery of a finely-polished stone implement in a tertiary gravel, except as an intrusive deposit. It is a violent anachronism, which is without a parallel in other countries. Even the discovery of a compound implement, as a stemmed arrowhead, in strata of tertiary date, is, with our present knowledge, quite out of the question.
Although there are well recognized signs of glacial action in South America, it is not certain that the glacial epoch coincided in time in the two continents. That there was a reasonable approximation is probable from the appearance of later deposits. We may suppose therefore that the habitable area of the New World was notably less at that period, and that the existing tribes were confined to a much narrower space. This would force them into closer relations, and tend powerfully to the production of that uniformity of type to which I have before referred.
We might also expect to discover in the tropical regions of America more frequent evidence of the primitive Americans than in either temperate zone. This has not been the case, probably because the geologic deposits of the tropics have been less investigated. Throughout the West Indies there is an entire absence of palæolithic remains. Those islands were first peopled by tribes in the polished stone stage of culture. In the valley of Mexico human remains have been disinterred from a volcanic deposit of supposed tertiary age, and you have all heard of those human footprints which Dr. Earl Flint has unearthed in Nicaragua. These are found under layers of compact volcanic tufas, separated by strata of sand and vegetable loam. There can be no doubt of their human origin or of their great antiquity; but no geologist need be informed of the difficulty of assigning an age to volcanic strata, especially in a tropical country, subject to earthquakes, subsidence and floods.[28]
It would not be in accordance with my present purpose to examine the numerous alleged finds of human remains in the strata of the tertiary and quaternary. All such furnish data for the pre-historic chronology of America, and should be carefully scrutinized by him who would obtain further light upon that chronology. I must hasten to some other considerations which touch the remote events to which I am now alluding.
Since a comparison of the fauna of South America and Africa, and a survey of the sea-bottom between those continents, have dispelled the dream of the ancient Atlantis, and relegated that land connection at least to the eocene period of the tertiary, no one can suppose the American man to have migrated from Africa or southwestern Europe. For other and equally solid reasons, no immigration of Polynesians can be assumed. Yet zoölogists, perfectly willing to derive man from an anthropoid, and polygenists to the utmost, hesitate to consider man an autochthon in the New World. There is too wide a gap between the highest monkeys and the human species in this continent.[29] Discoveries of fossil apes might bridge this, but none such has been reported.
If we accept the theory that man as a species spread from one primal centre, and in the higher plasticity of his early life separated into well defined races, which became unalterably fixed not much later than the close of the glacial epoch—and this theory appears to be that now most agreeable to anthropologists—then the earliest Americans made their advent on this continent as immigrants. This is our first fact in their pre-historic chronology; but before we can assign it an accurate position on the scale of geologic time, we must await more complete discoveries than we now have at our command.
We must also wait until our friends the geologists have come to some better understanding among themselves as to what took place in the pleistocene age. You have heard me talking freely about the glacial epoch and its extension in America; but geologists are by no means of one mind as to this extension, and a respectable minority of them, led by Sir J. William Dawson, deny the existence or even possibility of any continental glacier. What others point out as a terminal moraine they explain to be “nothing but the southern limit of the ice-drift of a period of submergence.”[30]
It is clear that when we speak about the migration of the Americans at a time when the polar half of each continent was either covered with a glacier thousands of feet thick, or submerged to that depth beneath an arctic sea, we have to do with geographical conditions totally unlike those of to-day. I call attention to this obvious fact because it has not been obvious to all writers.
In your archæological reading you will rarely come across a prettier piece of theoretical history than Mr. Lewis A. Morgan’s description of the gradual peopling of the two Americas by tracing the lines of easiest subsistence. He begins at the fishy rivers of the northwest coast, and follows the original colony which he assumes landed at that point, all the way to Patagonia and Florida.[31] But how baseless becomes this vision when we consider the geography of America as it is shown by geology to have been at a period contemporary with the earliest remains of man! We know to a certainty that the human race had already spread far and wide over both its continental areas before Mr. Morgan’s lines of easiest nutrition had come into existence.
Properly employed, a study of those geologic features of a country which determine its geography will prove of vast advantage in ascertaining the events of pre-historic time. These features undoubtedly fixed the lines of migration and of early commerce. Man in his wanderings has always been guided by the course of rivers, the trend of mountain chains, the direction of ocean currents, the position of deserts, passes and swamps. The railroad of to-day follows the trail of the primitive man, and the rivers have ever been the natural highways of nations. The theories of Morgan therefore remain true as theories; only in their application he fell into an error which was natural enough to the science of twenty years ago. Perhaps when twenty years more shall have elapsed, the post-tertiary geology of our continent will have been so clearly defined that the geography of its different epochs will be known sufficiently to trace these lines of migration at the various epochs of man’s residence in the western world, from his first arrival.
I have now set before you, in a superficial manner it is true, the various sources from which we may derive aid in establishing the pre-historic chronology of America. I have also endeavored, to a limited extent, to express myself as to the relative value of these sources. None of them can be neglected, and it will be only from an exhaustive study of them all that we can expect to solve the numerous knotty problems, and lift the veil which hangs so darkly on all that concerns the existence of the American race before the sixteenth century.
We are merely beginning the enormous labor which is before us; we have yet to discover the methods by which we can analyze fruitfully the facts we already know. But I look forward with the utmost confidence to a rich return from such investigations. The day is coming, and that rapidly, when the pre-historic life of man in both the New and the Old World will be revealed to us in a thousand unexpected details. We have but to turn backward about thirty years to reach a time when the science of pre-historic archæology was unknown, and its early gropings were jeered at as absurdities. Already it has established for itself a position in the first rank of the sciences which have to do with the highest of problems. It has cast a light upon the pathway of the human race from the time that man first deserved his name down to the commencement of recorded history. Its conquests are but beginning. Year by year masses of new facts are brought to knowledge from unexpected quarters, current errors are corrected, and novel methods of exploration devised.
As Americans by adoption, it should be our first interest and duty to study the Americans by race, in both their present and past development. The task is long and the opportunity is fleeting. A century more, and the anthropologist will scarcely find a native of pure blood; the tribes and languages of to-day will have been extinguished or corrupted. Nor will the archæologist be in better case. Every day the progress of civilization, ruthless of the monuments of barbarism, is destroying the feeble vestiges of the ancient race; mounds are levelled, embankments disappear, the stones of temples are built into factories, the holy places desecrated. We have assembled here to aid in recovering something from this wreck of a race and its monuments: let me urge upon you all the need of prompt action and earnest work, inasmuch as the opportunities we enjoy will never again present themselves in such fulness.
