to the west the ice streamed out across, the Irish Sea, the islands to the west of Scotland, and ended far out into what is now the Atlantic. But these glaciers, vast as they were, were very small compared with the glaciers that streamed out from the mountains

of Norway and Sweden. These great glaciers invaded England to the southwest, beat back the glacier ice of Scotland from the floor of the North Sea, overran Denmark, and spread their mantle of bowlder clay far south into Germany.

While such was the condition of things to the north, the glaciers of the Alps were many times greater than at present. All the valleys were filled with glacier ice, and they spread far out on the plains of

Southern Germany and westward into France. The mountains of Southern

France and the Pyrenees also supported their separate system of

glaciers. Ice also descended from the mountains of Asia Minor and North

Africa. In America we meet with traces of glaciers on a vast scale;

but we can not pause to describe them here.

76

It need not surprise us, therefore, to learn of reindeer and musk-sheep feeding on stunted herbage in what now constitutes Southern France. When a continuous mantle of snow and ice cloaked all Northern Europe, it

is not at all surprising to find evidence of an extremely cold climate prevailing throughout its southern borders. We thus see how one piece of evidence fits into another, and therefore we may, with some confidence, endeavor to find proofs of more genial conditions when the snow and ice disappeared, and a more luxuriant vegetation possessed the land, and animals accustomed to warm and even tropical countries roamed over

a large extent of European territory. In Switzerland it was long ago pointed out that after the ancient glaciers had for a long time occupied the low grounds of that country they, for some cause, retreated to

the mountain valleys, and allowed streams and rivers to work over the

debris left behind them. At Wetzikon most interesting conclusions have been drawn. We there learn that, after the retreat of the glaciers, a lake occupied the place, which in course of time became filled with peat, and that subsequently the peat was transformed into lignite. To judge from the remains of animals and plants, the climate must have been at least as warm as that at present; and this condition of things must have prevailed over a period of some thousands of years to explain the thick deposits of peat, from which originated the lignites. But we also know that this period came to an end, and that once more the ice descended. This is shown by the fact that directly overlying the lignite beds are alternating layers of sand and gravel, and, resting on these, glacier-born bowlders. The same conclusion follows from the discoveries made at many other places. 77 In Scotland it is well known that the bowlder clay contains every now and then scattered patches of peat and beds of soil either deposited in lakes or rivers. The only explanation that can be given for their presence is that they represent old land surfaces; that is, when the land was freed from ice, and vegetation had again clothed it in a mantle of green. In this cut is shown one of these beds. Both above and below are the beds of bowlder clay. The peat in the centre varies from an inch to a foot and a half in thickness, and contains many fragments of wood, sticks, roots, etc.; and of animals, numerous beetles were found, one kind of which frequents only places where deer and ruminant animals abound. Diagram of Interglacial Bed------------ From a large number of such discoveries it is conclusively shown that, after all, Scotland was smothered under one enormous glacier, a change of climate occurred, and the ice melted away. Then Scotland enjoyed a climate capable of nourishing sufficient vegetation to induce mammoths, Irish deer, horses, and great oxen to occupy the land. But the upper bowlder clay no less conclusively shows that once more the climate became cold, and ice overflowed all the lowlands and buried under a new accumulation of bowlder clay such parts of the old land surface as it did not erode. Substantially the same set of changes are observed in English and German geology. Having thus given an outline of the climatic changes which took place in Europe during the Glacial Age, and the grounds on which these strange conclusions rest, we must now turn our attention to the appearance of 78 man. The uncertainties which hung over his presence in the earlier periods, spoken of in the former chapter, do not apply to the proofs of his presence during this age, though it is far from settled at what particular portion of the Glacial Age he came into Europe. We must remember we are to investigate the past, and to awaken an interest in the history of a people who trod this earth in ages long ago. The evidence on which we establish a history of the early tribes of Europe is necessarily fragmentary, but still a portion here and a piece there are found to form one whole, and enable us to form quite a vivid conception of manners and times now very far remote. It is not claimed that we have surmounted every difficulty--on the contrary, there is yet much to be deciphered; but, in some respects, we are now better acquainted with these shadowy tribes of early times than with those whose history has been recorded by the historian's facile pen. He has given us a record of blood. He acquaints us with the march of vast armies, tells us of pillaged cities, and gives us the names of a long roll of titled kings; but, unfortunately, we know little of the home life, the occupation, or of those little things which make up the culture of a people. But the knowledge of primitive tribes, gathered from the scanty remains of their implements, from a thorough exploration of their cavern homes, has made us acquainted with much of their home life and surroundings: and we are not entirely ignorant as to such topics as their trade, government, and religion. We must not forget that this is a knowledge of tribes and peoples who lived here in times immeasurably ancient as compared with those in existence at the very dawn of history. 79 We must try and form a mental picture of what was probably the primitive state of man; and a little judicious reasoning from known facts will do much for us in this direction. Some writers have contended that the first condition of man was that of pleasing innocence, combined with a high degree of enlightenment, which, owing to the wickedness of mankind, he gradually lost. This ideal picture, however consonant with our wishes, must not only give way before the mass of information now at our command, but has really no foundation in reason; "or, at any rate, if this primitive condition of innocence and enlightenment ever existed, it must have disappeared at a period preceding the present archaeological investigations." Nothing is plainer than that our present civilization has been developed from barbarism, as that was from savagism. We need go back but a few centuries in the history of any nation, before we find them emerging from a state of barbarism. The energy and intelligence of the Anglo-Saxon has spread his language to the four corners of the globe; he has converted the wilderness into fruitful fields, and reared cities in desert lands: yet his history strikingly illustrates our point. A century back, and we are already in a strange land. The prominent points of present civilization were yet unthought of. No bands of iron united distant cities; no nerves of wire flashed electric speech. The wealth of that day could not buy many articles conducive of comfort, such as now grace the homes of the poor. The contrast is still more apparent when we recall another of the countless centuries of the past. England, with Europe, was but just awakening to modern life. Printing had but just been invented. Great discoveries had been made, and mankind was but just beginning those first feeble efforts which were to bring to us our modern comforts. But a millennium of years ago, and the foundation of English civilization 80 had but just been laid by the union of the rude Germanic tribes of the Saxons and the Angles. Similar results attend the ultimate analysis of any civilization. It was but yesterday that wandering hordes, bound together by the loose cohesion of tribal organization, and possessing but the germ of modern enlightenment, held sway in what is now the fairest portion of the world: and we, the descendants of these rude people, must reflect that the end is not yet--that the onward march of progress is one of ever hastening steps--and that, in all human probability, the sun of a thousand years hence will shine on a people whose civilization will be as superior to ours as the light of day exceeds the mellow glow of a moon-lit night. If such are the changes of but a few centuries, what must we not consider the changes to have been during the countless ages that have sped away since man first appeared on the scene! The early Greek and Roman writers were much nearer right when they considered primitive man to have been but a slight degree removed from the brute world. Horace thus expresses himself: "When animals first crept forth from the newly formed earth, a dumb and filthy herd, they fought for acorns and lurking places--with their nails, and with fists--then with clubs--and at last with arms, which, taught by experience, they had forged. They then invented names for things, and words to express their thoughts; after which they began to desist from war, to fortify cities, and enact laws." The learning of modern times leads to much the same conclusion. It is evident that primitive man must have been destitute of metals; for it requires a great deal of knowledge and experience to extract metals from their ores. In the eyes of savages, the various metallic ores are simply so many varieties of stone--much less valuable for his purposes 81 than flint, or some other varieties. We know it to be historically true, that a great many nations have been discovered utterly destitute of any knowledge of metals. When we reflect how much of our present enlightenment is due to the use of metals, we can readily see that their discovery marks a most important epoch in the history of man. There is, then, every reason to suppose that stone was a most important article for primitive man. It was the material with which he fought his battle for existence, and we need not be surprised that its use extended through an enormously long period of time. Not only was primitive man thus low down in the scale, but of necessity his progress must have been very slow. The time during which men were utterly destitute of a knowledge of metals, far exceeds the interval that has elapsed since that important discovery. Scholars divide the stone age into two parts. In the first, the stone implements, are very few, of simple shapes, and in the main formed of but one variety of stone--generally flint~-and they were never polished. In the second division, we meet with a great many different implements, each adapted to a different purpose. Different varieties of stone were employed, and they also made use of bone, shell, and wood, which were often beautifully polished. From what we have learned of the development of primitive society, it will not surprise us to learn that the first division of the age of stone comprises a vastly greater portion of time, and is far more ancient, than the second. We will give an outline showing the order of use of different materials; but it is here necessary to remark that Bronze was the first metal that man learned to use, and Iron the second. 82 ORDER IN WHICH DIFFERENT MATERIALS WERE USED FOR WEAPONS AND IMPLEMENTS BY PRIMITIVE MAN. Age of Stone. Rough, or Old Stone Age--Paleolithic. Polished or New Stone Age--Neolithic. Age of Metals. Bronze Age. Iron Age. In this outline the words Paleolithic and Neolithic are the scientific terms for the two divisions of the Stone Age, and will be so used in these pages. The only races of men that we could expect to find in Europe during the Glacial Age would be Paleolithic tribes, and it is equally manifest that we must find traces of them in beds of this age, or in association with animals that are characteristic of this age, or else we can not assert the existence of man at this time. The valley of the river Somme, in Northern France, has become classical ground to the student of Archaeology, since it was there that such investigations as we have just mentioned were first and most abundantly made. It is now well known that the surface features of a country--that is, its hills and dales, its uplands and lowlands--are mainly due to the erosive power of running water. Our rivers have dug for themselves broad valleys, undermined and carried away hills, and in general carved the surface of a country, until the present appearance is the result. It must be confessed that when we perceive the slow apparent change from year to year, and from that attempt to estimate the time required to produce the effects we see before us, we are apt to shrink from the lapse of time demanded for its accomplishment. Let us not forget that "Time is long," and that causes, however trifling, work stupendous results in the course of ages. 83 Picture of Paleolithic Flints.-------- But a river which is thus digging down its channel in one place, deposits the materials so dug away at other and lower levels, as beds of sand and gravel. In the course of time, as the river gradually lowers its channel, it will leave behind, at varying heights along its banks, scattered patches of such beds. Wherever we find them, no matter how far removed, or how high above the present river, we are sure that at some time the river flowed at that height; and standing there, we may try and imagine how different the country must have looked before the present deep valley was eroded. In the case of the river Somme, we have a wide and deep valley, a large part of which has been excavated in chalk rock, through which the river now winds its way in a sinuous course to the English Channel. Yet we feel sure that at some time in the past it was a mighty stream, and that its waters surged along over a bed at least two hundred feet higher than now. In proof of this fact we still find, at different places along the chalky bluff, stretches of old gravel banks, laid down there by the river, "reaching sometimes as high as two hundred feet above the present water level, although their usual elevation does not exceed forty feet." The history of the investigation of the ancient gravel beds of the Somme is briefly this: More than one instance had been noted of the finding of flint implements, apparently the work of men, in association with bones 84 of various animals, such as hyenas, mammoths, musk-sheep, and others, which, as we have just seen, lived in Europe during the Glacial Age. In a number of cases such finds had been made in caves. But for a long time no one attributed any especial value to these discoveries, and various were the explanations given to account for such commingling. A French geologist, by the name of Boucher DePerthes, had noted the occurrence of similar flint implements, and bones of these extinct animals, in a gravel pit on the banks of the Somme, near Abbeville, France. He was convinced that they proved the existence of man at the time these ancient animals lived in Europe. But no one paid any attention to his opinions on this subject, and a collection of these implements, which he took to Paris in 1839, was scarcely noticed by the scientific world. They were certainly very rude, and presented but indistinct traces of chipping, and perhaps it is not strange that he failed to convince any one of their importance. He therefore determined to make a thorough and systematic exploration of these beds at Abbeville. In 1847 he published his great work on this subject, giving over sixteen hundred cuts of the various articles he had found, claiming that they were proof positive of the presence of man when the gravels were depositing. Picture of Flint Implements, so-called.------ Now there are several questions to be answered before the conclusions of the French geologist can be accepted. In the first place, are these so-called flint implements of human workmanship? From our illustrations, we see that they are of an oval shape, tending to a cutting edge all around, and generally more or less pointed at one end. The testimony of 85 all competent persons who have examined them is, that however rude they may be, they were undoubtedly fashioned by man. Dr. C. C. Abbott has made some remarks on implements found in another locality, equally applicable to the ones in question. He says: "We find, on comparing a specimen of these chipped stones with an accidentally fractured pebble, that the chipped surfaces of the former all tend toward the production of a cutting edge, and there is no portion of the stone detached which does not add to the availability of the supposed implement as such; while in the case of a pebble that has been accidentally broken, there is necessarily all absence of design in the fracturing." Like the watch found on the moor, they show such manifest evidence of design, that we can not doubt that they were produced by the hand of man. But it is not enough to know that they are artificial, we must also know that they are of the same age as the beds in which they are found. Section of Gravel Pit.----------- This cut represents a section of a gravel pit at St. Acheul, on the Somme. The implements are nearly always found in the lowest strata, which is a bed of gravel from ten to fourteen feet thick. Overlying this are beds of marl, loam, and surface soil, comprising in all a depth of fourteen feet. It has been suggested that the implements are comparatively recent, and have sunk down from above by their own weight, or perhaps have been buried in artificial excavations. The beds are however too compact to admit of any supposition that they may have been sunk there; and if buried in any excavation, evident traces of such 86 excavation would have remained. We can account for their presence there in no other way than, that when the river rolled along at that high elevation, and deposited great beds of sand, these implements were someway lost in its waters, and became buried in the gravel deposits. Finally, we have to consider the age of the deposits. This is a question that can be answered only by geologists, and we may be sure that more than ordinary attention has been bestowed upon them. The remains of many animals characteristic of the Glacial Age were found in the beds at Abbeville. These include those of the elephants, rhinoceros, hyenas, cave-bear, and cave-lion. In the formation of these gravel beds, ice has undoubtedly played quite an important part. Bowlders that could have got there only by the aid of ice, are found in several localities. Evidence gathered from a great many different sources all establish the fact that these gravels date as far back as the close of the Glacial Age at least, and there are some reasons for supposing them to be interglacial. We can easily see that the melting away of the immense glaciers that we have been describing would produce vast floods in the rivers, and it is perhaps owing to the presence of such swollen rivers that are due the great beds of surface soil, called loam or loess, found in all the river valleys of France and Germany. These deposits frequently overlie the gravel beds. They are then of a later date than the beds in which are found such convincing proofs of the presence of man, and if they themselves date from the close of the Glacial Age, it is no longer a question whether the gravel beds themselves belong to that age. Thus we see that we can no longer escape the conclusions of Boucher DePerthes. 87 The discovery of rudely worked flints in the drift of the Somme River thus establishes the fact that some time during the Glacial Age, man in a Paleolithic state lived in France. Geological terms convey to us no definite ideas as to the lapse of time, and we have an instinctive desire to substitute for them some term of years. In most cases this is impossible, as we have no means to measure the flight of past time, nor are we yet prepared to discuss the question of time, since to do so we must learn a great deal more about the cause of the Glacial Age. We might, however, cite statements which can not fail to impress us with the fact that a great extent of time has passed. In the case of the river Somme we have a valley in some places a mile or more in width, and about two hundred feet in depth. This has mostly been excavated in chalk rock. Taking our present large rivers as a basis, it would require from one to two hundred thousand years for the Somme to perform this work. It will not do, however, to take the present action of our rivers as a guide, since we have every reason to suppose this work went forward much more rapidly in past times. But we can not escape the conclusion that it demands a very long time indeed to explain it. The valley has remained in its present shape long enough to admit the formation of great beds of peat in some portions. Peat is formed by the decomposition of vegetable growth. Its growth is in all cases slow, depending entirely upon local circumstances. European scholars who have made peat formation a special study assure us that to form such immense beds as occur near Abbeville, several thousand years are required, even under the most favorable conditions. Yet we would be scarcely willing to rest such important conclusions as 88 the foregoing on the researches of one individual, or in one locality. As already stated, DePerthes made his discoveries public in 1847. Yet they were so opposed to all that had been believed previously, that but few took the pains to investigate for themselves. In 1853, Dr. Rigollot, of Amiens, who had been skeptical as to DePerthes, commenced to look for himself in the gravel beds at St. Acheul, about nine miles below Abbeville. As might be expected, he was soon convinced. Picture of Paleolithic Flint, England.------ It may be said that the scientific world formally accepted the new theory when such English scientists as Evans, Falconer, Lyell, and Prestwich reported in its favor. Since that time, many discoveries of ancient implements have been made at various places in France and England under circumstances similar to those in the valley of the Somme. In England they have been found along almost all the rivers in the southern and south-eastern part. One class of discoveries there gives us new ideas as to the extent of time that has passed since they were deposited. That is where they occur in gravel beds having no connection with the present system of rivers. In one case the gravel forms a hill fifteen feet high, situated in the midst of a swampy district, surrounded on all sides by low, flat surfaces. Several such instances could be given; but, in all such cases, we can not doubt that, somewhere near, there once rolled the waters of an ancient river, that man once hunted along its banks, and that, owing to some natural cause, the waters forsook their ancient bed--and that since then, in the slow course of ages, the action of running water has removed so much of the 89 surface of the land near there, that we can not guess at its ancient configuration: we only know, from scattered patches of gravel, that we are standing on the banks of an ancient water-course. One instance, illustrative of the great change that has come over the surface features of the country, demanding for their accomplishment a great lapse of time, is furnished by the Isle of Wight. That island is now separated from the mainland by a narrow channel, called the South Hampton Water, or the Solent Sea. It is now known that this is nothing but an old river channel, in which the sea has usurped the place of the river. The coast is a river embankment, with the usual accompaniments of gravel beds, flint implements, and fresh water shells. On the shores of the island we find the opposite bank of the old river. A very great change must have taken place in the surface features before the sea could have rolled in and cut off the Isle of Wight from the mainland. In speaking of the length of time demanded for this change, Dr. Evans says: "Who can fully understand how immeasurably remote was the epoch when what is now that vast bay was high and dry land, and a long range of chalk downs, six hundred feet above the sea, bounded the horizon on the South? And yet that must have been the sight that met the eye of primitive man who frequented the banks of that ancient river, which buried their handiwork in gravels that now cap the cliffs--and of the course of which so strange and indubitable a memorial subsists in what has now become the Solent Sea?" The illustrations scattered through this essay are representations of 90 the stone implements found in the drift of European rivers. During all the long course of time supposed to be covered by the Paleolithic Age, there are but very few evidences of any improvement, as far as we can judge from the implements themselves. This is in itself a melancholy proof of the low condition of man. He had made so little advance in the scale of wisdom, he possessed so little knowledge, he was so much a creature of instinct, that, during the thousands of years demanded for this age, he made no appreciable progress. The advance of the last century was many times greater than that of the entire Paleolithic Age. A blow struck on one end of a piece of flint will, owing to the peculiar cleavage of flint, split off pieces called flakes. This is the simplest form of implement used by man. It is impossible to say with certainty how they were used; but, from the evidence observed on them, they were probably used as scrapers. The men of that day doubtless knew some simple method of preparing clothing from the skins of the animals they had killed, and probably many of these sharp-rimmed flakes were used to assist in this primitive process of tanning. Illustration of Flint Flakes.-------- When the piece of flint itself was chipped into form, it was one whose shape would indicate a spear-head or hatchet. We present illustrations of each. Forms intermediate between these two are found. Some have such a thick heavy base that it is believed they were used in the hand, and had no handle or haft. Others, with a cutting edge all round, may have been provided with a handle. M. Mortillet, of France, who has had excellent opportunities of 91 studying this question very thoroughly, thinks that the hatchet was the only type of implement they possessed, and that it was used for every conceivable purpose--but that their weapon was a club, all traces of which have, of course, long since vanished away. Illustrations of Spear Head Type and Hatchet Type.------ These few implements imply that their possessors were savages like the native Australians. In this stage of culture, man lived by hunting, and had not yet learned to till the ground, or to seek the materials out of which his implements were made by mining. Re merely fashioned the stones which happened to be within reach in the shallows of rivers as they were wanted, throwing them away after they had been used. In this manner the large numbers which have been met with in certain spots may be accounted for. Man at this time appears before us as a nomad hunter, poorly equipped for the struggle of life, without knowledge of metals, and ignorant of the art of grinding his stone tools to a sharp edge. Of course we can not hope to learn much of their social condition other than that just set forth. DePerthes found some flints which show evidence of their human origin, and yet it would be very difficult to say what was their use. He thinks they may have a religious significance, and has set forth a great variety of eloquent surmises respecting them. It only need be said that such theorizing is worse than useless. That while it is very probable these tribes had some system of belief, yet there is no good reason for supposing these flints had any connection with it. It has been supposed, from another series of wrought flints, that the men of this epoch were 92 possessed of some sentiments of art, as pieces have been found thought to represent the forms of animals, men's faces, birds, and fishes; but as very few have been able to detect such resemblances, it is safe to say they do not exist. As the love of adornment is almost as old as human nature itself, we may not be surprised to find traces of its sway then. Dr. Rigollot found little bunches of shells with holes through either end. The supposition is that these were used as beads; which is not at all strange, considering how instinctively savage men delight in such ornaments. These ancient hunters made use of beads partially prepared by nature. Europe is not the only country where the remains of this savage race are found. They are found in the countries bordering the Mediterranean in Northern Africa, and in Egypt. In this latter country they are doubtless largely buried under the immense deposits of Nile mud; yet in 1878 Professor Haynes discovered in Upper Egypt scrapers and hatchets, pronounced by archaeologists to be exactly similar to those of the river Somme. We are not informed as to their geological age, but there can be no question that they are much older than any monument of Egyptian civilization hitherto known. Paleolithic implements have also been found in Palestine and in India. In the latter country the beds are so situated that they present the same indicia, of age as do those of the Somme Valley. A great portion of the formation has been removed, and deep valleys cut in them by running water. They have also been found in at least one locality in the United States; that is in the glacial gravel of the valley of the Delaware at Trenton, New Jersey. We must not confound these remains 93 with those of the Indian tribes found scattered over a large extent of surface. Those at Trenton also are not only in all respects, except materials, similar to those of the Somme, but are found imbedded in a formation of gravel that was deposited at least as far back as the close of the Glacial Age, thus requiring the passage of the same long series of years since they were used, as do the implements of European rivers. We must also bear in mind that no country has been so carefully explored for these implements as has Europe, and that the very country, Asia, where, for many reasons, we might hope to find not only unequivocal proofs of man's presence but from our discoveries be able to clear up many dark points, as to the race, origin, and fate of these primitive tribes, is yet almost a sealed book. But the scattered discoveries we have instanced show us that the people whose implements have been described in this chapter were very widely dispersed over the earth, and everything indicates that they were far removed from us in time. The similarity in type of implements shows that, wherever found, they were the same people, in the same low savage state of culture--"Alike in the somber forests of oak and pine in Great Britain, and when surrounded by the luxuriant vegetation of the Indian jungle." We have yet two important points to consider. The first is, what race of men were these river tribes? and second, when did they arrive in Europe? Did they precede the glacial cold? did they make their appearance during a warm interglacial period? or was it not until the final retreat of the glaciers that they first wandered into Europe? These questions are far from settled; yet they have been the object of a great amount of painstaking research. 94 To determine the first point, it is necessary that anatomists have skeletons of the men of this age, to make a careful study of them. But for a great many reasons, portions of the human skeleton are very rarely found in such circumstances that we are sure they date back to the Paleolithic Age, and especially is this true of the men of the River Drift. In a few instances fragmentary portions have been found. M. Quatrefages, of France, who is certainly a very high authority on these points, thinks that the hunter tribes of the River Drift belonged to the Canstadt race--"so named from the village of Canstadt, in Germany, near which a fossil skull was discovered in 1700, and which appears to be closely allied to the Neanderthal skull, discovered near Dusseldorf in 1857, and about which so much has been written." Quatrefages supposes that this type of man is still to be found in certain Australian tribes. These are not mere guesses, but are conclusions drawn from careful study by eminent European scholars. It is well known that a competent naturalist needs but a single fossil bone to describe the animal itself, and tell us its habits. So also anthropologists need but fragments of the human skeleton, especially of the skull, to describe characteristics of the race to which the individual belonged. Illustration of Neanderthal Man.----------- This cut, though an ideal restoration, is a restoration made in accordance with the results of careful study of fragmentary skulls found 95 in various localities in Europe. The head and the face present a savage aspect; the body harmonized with the head; the height was not more than five feet and a half; yet the bones are very thick in proportion to their length, and were evidently supplied with a powerful set of muscles, since the little protuberances and depressions where the muscles are attached are remarkably well developed. Huxley and Quatrefages have both pointed out that representatives of this race are to be found among some Australian tribes. "Among the races of this great island there is one, distributed particularly in the province of Victoria, in the neighborhood of Port Western, which reproduces in a remarkable manner, the characters of the Canstadt race." Not the least interesting result of this discovery is the similarity of weapons and implements. "With Mr. Lartet, we see in the obsidian lances of New Caledonia the flint heads of the lower alluvium of the Somme. The hatchet of certain Australians reminds us, as it did Sir Charles Lyell, of the Abbeville hatchet." Yet some hesitate about accepting these interesting inferences, thinking that the portions of the human skeleton thus far recovered, which are beyond a doubt referable to this period, are too fragmentary to base such important conclusions upon. This is the view of Boyd Dawkins, who thinks "we can not refer them to any branch of the human race now alive." "We are without a clew," continues he, "to the ethnology of the River Drift man, who most probably is as completely extinct as the woolly rhinoceros or the cave bear." Future discoveries will probably settle this point. It is yet a much disputed point to what particular portion of the Glacial Age we can trace the appearance of man. We can profitably note 96 the tendency of scientific thought in this direction. But a short time has elapsed since a few scholars here and there began to urge an antiquity for man extending back beyond the commonly accepted period of six thousand years. Though it is now well known and admitted that there are no good grounds for this estimate, yet such was its hold, such its sway over scientific as well as popular thought, that an appeal to this chronology was deemed sufficient answer to the discoveries of DePerthes, Schmerling, and others. It was but yesterday that this popular belief was overthrown and due weight given the discoveries of careful explorers in many branches, and the antiquity of man referred, on indisputable grounds, to a point of time at least as far back as the close of the preceding geological age. It seems as if here a halt had been called, and all possible objections are urged against a further extension of time. It is, of course, well to be careful in this matter, and to accept only such results as inevitably follow from well authenticated discoveries. But it also seems to us there is no longer any doubt that man dates back to the beginning of that long extended time we have named the Glacial Age. In the first place, we must recall the animals that suddenly made their appearance in Europe at the beginning of this age. Though there were a number of species, since become extinct, the majority of animal forms were those still living. These are the animals with which man has always been associated. There is therefore no longer any reason to suppose the evolution of animal life had not reached that stage where man was to appear. We need only recall how strongly this point was urged in reference to the preceding 97 geological epoch, to see its important bearings here. Mr. Boyd Dawkins has shown that the great majority of animals which invaded Europe at the commencement of this age, can be traced to Northern and Central Asia, whence, owing to climatic changes, they migrated into Europe. Inasmuch as man seems to have been intimately associated with these animals, it seems to us very likely that he came with them from their home in Asia. We think the tendency of modern discoveries is to establish the fact that man arrived in Europe along with the great invasion of species now living. Turning now to the authorities, we find this to be the accepted theory of many of those competent to form an opinion. In England Mr. Geikie has strongly urged the theory that the Glacial Age includes not only periods of great cold, but also epochs of exceptional mildness; and he strongly argues that all the evidence of the River Drift tribes can be referred to these warm interglacial epochs; in other words, that they were living in Europe during the Glacial Age. In answer to this it has been stated that the relics of River Drift tribes in Southern England overlie bowlder clay, and must therefore be later in origin than the Glacial Age. But, Mr. Geikie and others have shown that the ice of the last great cold did not overflow Southern England, so that this evidence, rightly read, was really an argument in favor of their interglacial age. The committee appointed by the British Association to explore the Victoria Cave, near Settle, urge this point very strongly in their 98 final report of 1878. To this report Mr. Dawkins, a member of the committee, records his dissent, but in his last great work he freely admits that man was living in England during the Glacial Age, if he did not, in fact, precede it. Mr. Skertchley, of the British coast survey, in 1879, announced the discovery in East Anglia of Paleolithic, implements underlying the bowlder clay of that section. Mr. Geikie justly regards this as a most important discovery. Finally Mr. Dawkins, in his address as President of the Anthropological section of the British Association, in 1882, goes over the entire ground. After alluding to the discovery of paleolithic implements in Egypt, India, and America, he continues: "The identity of implements of the River Drift hunter proves that he was in the same rude state of civilization, if it can be called civilization, in the Old and the New World, when the hand of the geological clock struck the same hour. It is not a little strange that this mode of life should have been the same in the forests of the North, and south of the Mediterranean, in Palestine, in the tropical forests of India, and on the western shores of the Atlantic." This, however, is not taken as proving the identity of race, but as proving that in this morning-time of man's existence he had nowhere advanced beyond a low state of savagism. Mr. Dawkins then continues: "It must be inferred from his widespread range that he must have inhabited the earth for a long time, and that his dispersal took place before the Glacial epoch in Europe and America. I therefore feel inclined to view the River Drift hunter as having invaded Europe in preglacial times, along with other living species which then appeared." He also points out that the evidence is that he lived in Europe during 99 all the changes of that prolonged period known as the Glacial Age. Sir John Lubbock also records his assent to these views. He says on this point: "It is, I think, more than probable that the advent of the Glacial Period found man already in possession of Europe." In our own country Prof. Powell says: "It is now an established fact that man was widely scattered over the earth at least as early as the beginning of the Quaternary period, and perhaps in Pliocene times." This completes our investigation of the men of the River Drift. We see how, by researches of careful scholars, our knowledge of the past has been enlarged. Though there are many points which are as yet hidden in darkness, we are enabled to form quite a clear mental picture of this early race. Out of the darkness which still enshrouds the continent of Asia we see these bands of savages wandering forth; some to Europe, Africa, and the west; others to America and the east. This was at a time when slowly falling temperature but dimly prophesied a reign of arctic cold, still far in the future. This race does not seem to have had much capacity for advancement, since ages came and went leaving him in the same low state. During the climax of glacial cold he doubtless sought the southern coasts of Europe along with the temperate species of animals. But whenever the climatic conditions were such that these animals could find subsistence as far north as England he accompanied them there, and so his remains are found constantly associated with theirs throughout Europe. Though doubtless very low in the scale, and at the very foot of the ladder of human progress, we are acquainted with no facts connecting them with the higher orders 100 of animals. If such exists, we must search for them further back in geological time. The men of the River Drift were distinctively human beings, and as such possessed those qualities which, developing throughout the countless ages that have elapsed, have advanced man to his present high position.

(55) Those who reject the proofs of the existence of man in Pliocene times because the evolution of life had not then reached a stage where we could hope to find man, are here confronted with a difficulty. If Mr. Dawkins be right (as stated above) then the various animals in question must have been living in Asia during the preceding Pliocene Age. There is no reason to suppose man was not associated with them, since he belongs to the same stage of evolution (Le Conte's "Elements of Geology," p. 568), and though, owing to climatic and geographical causes, the animals themselves might have been confined to Asia, there is surely no good reason why man may not, in small bands, and at various times, have wandered into Europe.

We have been delving, among the sands of ancient river bottoms for a proof of man's existence in far remote times. Slight and unsatisfactory as they may be to some, they are the materials with which we reconstruct a wondrous story of life and times removed from us by many a cycle of years. Men have frequently resorted to the caverns of the earth for protection. In places we find caves that served this purpose during the Paleolithic 106 Age. The men of the Drift, however, do not appear to have used them, save as temporary places of refuge, perhaps as a protection from bands of savage enemies, or from unusually inclement weather. But yet most surprising results have attended the exploration of caves in England, France, and Belgium. We find in those gloomy places that the men of the Drift were not the only tribes of men inhabiting Europe during the Glacial Age. In fact, living at later date than the Drift tribes, but still belonging to the Paleolithic Age, were tribes of people who appear to have utilized caverns and grottoes as places of permanent resort, and, judging from their remains, they had made considerable advance in the arts of living as compared with the tribes of the Drift. But before pointing out the grounds upon which these conclusions rest, it may be well to give a slight review of the history of cave research. The dread and awe which kept people away from caves during the Middle Ages preserved their contents for later discoverers. In the seventeenth century, some adventurous spirits began to search in them for what they called Unicorn horns, which were deemed a most efficacious remedy for various diseases. This search served the good purpose of bringing to light various fossil bones of animals, and calling the attention of scientific men to the same. The cave of Gailenreuth, in Bavaria, was explored by Dr. Goldfuss in 1810. He came to the conclusion that the bones of bears and other extinct animals were proofs of the former presence of the animals themselves. Dr. Buckland, a celebrated English writer, visited the cave in 1816, and became much interested in the work; so much so that when Kirkdale Cavern, in England, was discovered in 1821, he at once repaired to the spot and made a careful exploration. The results satisfied him 107 that hyenas and other extinct animals had once lived in England. He followed up his explorations in a number of cases, and published a work on this subject in 1822, which marks the commencement of a new era in cave research. In 1825 Kent's Cavern, near Torquay, was discovered, and Rev. J. McEnry made partial explorations in it. He discovered flint implements and perceived they might be a proof of the presence of man with these extinct animals. Dr. Buckland had not found these relics, or else had passed them by as of no importance, for he refused to entertain the theory that man and the extinct animals had been contemporaneous. Explorations made in France in 1827-8 had furnished such strong evidence on this point that it was deemed established by some scholars, but being opposed to the prevailing belief, nothing came of it. Illustration of Gailenreuth.--------- In 1829 Schmerling commenced his investigations in the caves of the valley of the Meuse. For years he continued his work under many difficulties. Sir Charles Lyell tells us he was let down day after day to the opening of the Engis Cave by a rope tied to a tree. Arriving there he crawled on all fours through a narrow passage way to the enlarged chamber, where, standing in mud and water, he superintended the investigations. He examined over forty of those caves, and published his results in 1833. He clearly showed that man must have been living along with various animals now extinct in Belgium. But, as before remarked, it was deemed sufficient answer to this careful explorer to point out that 108 his results were opposed to the accepted chronology, and so they were passed by. When the time at last came, and their true worth was recognized, Schmerling himself had passed away. We have already seen what great results followed the exploration of DePerthes in the river gravels. When it had been clearly established that man and extinct animals hid coexisted in Europe, the results of cave explorations were eagerly recalled, and governments vied with royal societies and private individuals in continuing the researches. The results are that a rich store of facts has been gathered from those gloomy resorts, illustrative of the later stages of Paleolithic art. A word as to the formation of caves, grottoes, caverns, and rock shelters. These vary greatly in size, some being so small as to furnish protection to but few individuals; others, especially caves, so large that whole tribes might have found a place of resort within their chambers. They are found in all limestone countries. The formation of caves is now recognized as due to natural causes acting slowly through many years. Limestone rock is very hard and durable, but chemistry teaches us that water charged with carbonic acid gas will readily dissolve it. Rain-water falling from the clouds is sure to come in contact with masses of decaying vegetable matter, which we know is constantly giving off quantities of this gas. Laden with this the water sinks into the ground, and, if it comes in contact with limestone, readily washes some of it away in solution. But beds of limestone rock are noted for containing great fissures through which subterranean waters penetrate far into the ground. We can readily see how this percolating water would dissolve and wear away the surface of the rocks along such a fissure, and in process of time we would have the 109 phenomenon of a stream of water flowing under ground. Owing to a great many causes--such, for instance, as the meeting of another fissure--we would expect that portions of this underground way would become enlarged to spacious halls. In some such a way as this it is now understood that all caves have originated. Owing to many natural causes the river may, after a while, cease to flow, leaving enlarged portions of its channel behind as a succession of chambers in a cave. But water would still come trickling in from the tops and sides, and be continuously dripping to the floor, where it speedily evaporates. When such is the case it leaves behind it the limestone it held in solution. So, in process of time, if the deposition is undisturbed, there will be formed over the floor of the cave a more or less continuous layer of limestone matter known as stalagmite. The same formations on the top and sides of the cave are called stalactites. In places where the drip is continuous the stalactite gradually assumes the shape of an immense icicle; while the stalagmite on the floor of the cave, underneath the drip, rises in a columnar mass to meet the descending stalactite. A union of these is not uncommon, and, we have pillars and columns presenting the strange, fantastic appearance on which tourists delight to dwell in their notes of travel. While these accumulations are in all cases very slow, still we can not measure the time since it commenced by the rate of present growth, because this rate varies greatly at different times and places even in the same cave. And we must also remark that this complete series of changes only occur in a few localities, the majority of caves being insignificant in size. 110 From what has been said as to the formation of caves, we would expect them to occur in river valleys, and this is the case, though in some instances there have been such immense changes in the surface level of the country that we can now find no trace of rivers near them. This is exactly similar to some gravel deposits, which, as we have seen, are occasionally found where is now no running water. The most noted caverns, however, are found high up on the banks of existing rivers. We can not doubt that the rivers were the cause of the caves. But having excavated their beds below the level of the then existing caves, they ceased to flow in them, and left them to be occupied by savage animals and the scarcely less savage men. But at times, swollen by floods, the river would again assert its supremacy and roll its waters through its old channels. These floods would not only tear up and rearrange whatever debris had already accumulated, but would introduce quantities of sediment and animal remains. In some such a manner as is here pointed out (though exactly how geologists are not agreed) caves were invaded, after being long occupied by men or animals, by floods of water. In many cases the evidence would seem to indicate that after such a visitation by water the cave and its water-rolled and water-arranged contents were left to silence, visited by neither man nor beast. In such instances stalagmitic coverings would gradually form over the confused debris, and in some places acquire a thickness of several feet. In some instances several such floors are found one above the other, pointing to a prolonged period of usage, and then a quiet stage, in which the drip of falling water alone broke the silence, and nature sealed up another chapter of cave biography beneath the layer of stalagmite. 111 One of the most important caves of England is Kent's Cavern, before mentioned. This cave was carefully explored under the direction of a committee appointed by the British Association, and to show the care and thoroughness of the work we need only state that this work occupied the greater portion of sixteen years, and hence the results obtained may be regarded as, in a general way, illustrative of the life of the cave dwellers. "This cave is about a mile east of Torquay harbor, and is of a sinuous character, running deeply into a hill of Devonian limestone, about half a mile distant from the sea. In places it expands into large chambers, to which various distinctive names have been given." Let us see what general results have been reached by this committee. The investigation disclosed several different beds of stalagmite, cave earth, and breccia. The lowest layer is a breccia. The matrix is sand of a reddish color, containing many pieces of rock known as red-grit and some pieces of quartz. This implies the presence of running water, which at times washed in pieces of red-grit. The surface features must have been quite different from the present, since now this rock does not form any part of the hill into which this cave opens. And this change in drainage took place before this lowest layer was completed, since not only bears, but men, commenced to visit the cave. The presence of bears is shown by numerous bones, and that of man by his implements. Illustration of Spear-head--Lower Breccia, Kent's Cavern.--- We must notice that all the implements found in the breccia are similar 112 to those of the Drift, being rudely formed and massive. No doubt these are the remains of Drift men, who, for some cause or other, temporarily visited the cave, perhaps contending with the cave bear for its possession. But a time at length arrived when for some reason neither animals nor man visited the cave. The slow accumulation of stalagmite went forward until in some places it had obtained a thickness of twelve feet. Freely admitting that we can not determine the length of time demanded for this deposition, yet none can doubt that it requires a very long time indeed. Says Mr. Geikie: "How many centuries rolled past while that old pavement was slowly accreting, no one can say; but that it represents a lapse of ages compared to which the time embraced by all tradition and written history is but as a few months, who that is competent to form an opinion can doubt?" But after this long period of quiet, from some source great torrents of water came rolling through the cave. We know this to be so, because in places it broke up this layer of stalagmite and washed it away, as well as large portions of the breccia below, and after the floods had ceased, occasionally inundations still threw down layers of mud and silt. This accumulation is known as cave earth, and is the layer containing the numerous remains of the Cavemen. Here the explorers were not only struck with the large number of implements, but at once noticed that they were of a higher form and better made. Instead of the rude and massive implements of the Drift tribes, we have more delicate forms chipped all around. And we also meet with those that from their form may have been used as the heads of spears or arrows. Flakes were also utilized for various pur implements, weapons, and ornaments of bone--a step in advance of Drift culture. They had "harpoons for spearing fish, eyed needles or bodkins for stitching skins together, awls perhaps to facilitate the passage of the slender needle through the tough, thick hides; pins for fastening 113 the skins they wore, and perforated badgers' teeth for necklaces or bracelets." Nothing of this kind has yet been shown as belonging to the men of the Drift. Illustrations of Spear-head and Flake----------- The bones of a large number of animals are also found in the cave earth. The most abundant is the hyena, and no doubt they dragged in a great many others; but the agency of man is equally apparent, as the bones have often been split for the extraction of marrow. Besides bones of the hyena, we have also those of the lion, tiger, bear, and reindeer. Illustration of Harpoons, Pin, Awl, and Needle--Kent's Cavern. With these animals man, from time to time, disputed possession of the cave. At one place on the surface of the cave earth is found what is known as the "black band." This is nothing more or less than the fireplace of these old tribes. Here we find fragments of partially consumed wood, bones showing the action of fire--in short, every thing indicating a prolonged occupancy by man. No one can doubt but that this deposit of cave earth itself requires a prolonged time for its accumulation. But this period, however prolonged, at length comes to an end. From some cause, both animals and man again abandoned the cave. Another vast cycle of years rolls away--a 114 time expressed in thousands of years--during which nature again spread over the entombed remains a layer of stalagmite, in some places equal in thickness to the first formation. Above this layer we come to a bed of mold containing remains of the later Stone Age, of the Bronze, and even of the Iron Age. Below the first layer of stalagmite--the completed biography of Paleolithic times; above, the unfinished book of the present. Such are the eloquent results obtained by the thorough exploration of one cave. The results of all the other explorations, in a general way, confirm these. Mr. Dawkins explored a group of caverns in Derbyshire, England. These caverns and fissures are situated in what is known as Cresswell Crags, the precipitous sides of a ravine through which flows a stream of water dividing the counties of Derby and Nottingham. This cut represents the different strata in Robin Hood cave. It will be seen that, at one place, the stalactite has united with the stalagmite below. It is not necessary to go into the details of this exploration. All the relics of man found in d, c, and the lower portions of b, are the rude and massive forms peculiar to the River Drift tribes. But the relics found in the breccia a, and the upper portion of the cave earth b, denote a sudden advance in culture. The rude tools of the lower strata are replaced by more highly finished ones of flint. Illustration of Robin Hood Cave.----------- The most important discovery was that of a small fragment of rib, with its polished surface ornamented with the incised figure of a horse. 115 The peculiar value of this discovery is, that it serves to connect the Cavemen of England with those of the continent who, as we shall afterward see, excelled in artistic work of this kind. In another cave of this series, in association with similar flints, were found the following bone implements. We can only conjecture the use of the notched bone. The pieces of reindeer horn, terminating in a scoop, may have served as a spoon to extract marrow. Illustration of Horse Incised on Piece of Rib.------ We must not fail to notice that the more highly finished relics of the Cavemen are found in strata overlying those of the River Drift; and, in the case of Kent's Cavern, these two sets of implements are separated by a layer of stalagmite requiring a very prolonged time for its formation. This would imply that the Cavemen came into England long after the tribes of the River Drift; and, judging from the relics themselves, they must have been a distinct people. We must recall how completely the climate and animals in England varied during the Glacial Age. We have also seen how closely connected the River Drift tribes were with the animals of the warm temperate regions. Coming at a later date, totally distinct from them in culture are those Cavemen--perhaps they may prove to be associated with the Arctic animals. But, before speculating on this point, we must learn the results attending the exploration of the caves of Belgium, France, and other countries on the continent of Europe. 116 Illustration of Bone Implements--Cresswell Crags.----------- In the valley of the river Meuse (Belgium), and its tributaries, have been found a number of caves and rock-shelters. It was in the caves of the Meuse that Schmerling made his explorations. When the real value of his work was recognized, the Belgian government had a thorough exploration made by M. Dupont, director of the Royal Museum in Brussels. This gentleman scientifically examined forty-three of these resorts. His opinions, therefore, are deserving of great weight; but, unfortunately, they are not accepted by all. These caves vary greatly in size--many being mere rock-shelters. From their position, we are at once struck with the prolonged period of time necessary to explain their formation. They are found at very different heights along the river's bank. In one case two caves are so situated that the river must have sunk its bed nearly two hundred feet between the time of their formation. M. Dupont thinks the evidence very clearly points to the presence of two distinct stages in cave life--one of which he calls the Mammoth period, and the other, which is more recent, the Reindeer. It is, however, known that the mammoth lived all through the Reindeer epoch, if not to later times; so the names bestowed on these periods do not seem very appropriate. We can readily see, however, that, while the names might be wrong, the two periods might be reality. In many cases, the same cave contained remains of both stages, separated by layers of cave earth, and it is noticed that, in such cases, those of the Reindeer stage are invariably of a later date. In general terms, M. Dupont finds that the 117 implements of the Mammoth period are of a rude make, consisting of a poor kind of flint, and poorly finished. But, in beds of the Reindeer epoch, the flint implements consist, principally, of well-shaped blades and flakes--with numerous bodkins, or awls--javelins, or arrowheads--besides articles of bone and horn such as harpoons, and teeth of various animals drilled as if suspended for ornaments. Their workmanship indicates decidedly more skill than that of the implements obtained from the lower levels. But the most remarkable finds of the Reindeer epoch consist of portions of reindeer horn, showing etchings or engravings which have been traced by some sharp point, no doubt by a flint implement. One small bit of horn has been cut or scraped so as to present the rude outline of a human figure. So far the evidence seems to bear out the same conclusions as do those of the British caves, though it also shows that the men of the Drift inhabited caves quite extensively. We must remember, however, that the greatest wealth of cave relics belongs to the so-called Cavemen, but that savage tribes have always resorted to caves as a place for occasional habitation. It is in France that we find the greatest wealth of relics of Cavemen. Sir John Lubbock has left us a description of the valley of the Vezere, where these caverns occur. The Vezere is a small tributary of the Dordogne. "The rivers of the Dordogne run in deep valleys cut through calcareous strata: and while the sides of the valley in chalk districts are generally sloping, in this case, owing probably to the hardness of the rock, they are frequently vertical. Small caves and grottoes frequently occur: besides which, as the different strata possess unequal power of resistance against atmospheric influence, the face of the rock 118 is, as it were, scooped out in many places, and thus 'rock-shelters' are produced. In very ancient times these caves and rock-shelters were inhabited by men, who have left behind them abundant evidence of their presence. "But as civilization advanced, man, no longer content with the natural but inconvenient abode thus offered to him, excavated chambers for himself, and in places the whole face of the rock is honey-combed with doors and windows, leading into suits of rooms, often in tiers one over the other, so as to suggest the idea of a French Petra. Down to a comparatively recent period, as, for instance, in the troublous times of the Middle Ages, many of these, no doubt, served as very efficient fortifications, and even now some of them are in use as storehouses, and for other purposes, as, for instance, at Brantome, where there is an old chapel cut in solid rock. "Apart from the scientific interest, it was impossible not to enjoy the beauty of the scene which passed before our eyes, as we dropped down the Vezere. As the river visited sometimes one side of the valley, sometimes the other, so we had at one moment rich meadow lands on each side, or found ourselves close to the perpendicular and almost overhanging cliff. Here and there we came upon some picturesque old castle, and though the trees were not in full leaf, the rocks were, in many places, green with box and ivy and evergreen oak, which harmonized well with the rich yellow brown of the stone itself." Thus it will be seen this valley has been a favorite resort for people at widely different times, and amongst others, the cave dwellers of the Paleolithic Age. As in the caves of Belgium, some of them are at a 119 considerable height above the stream, while others are but little above the present flood line. Mr. Dawkins refers us to the results of the exploration of a French scientist in one of the grottoes of this section, which seem to be exactly similar to the results obtained from the caves of Cresswell Crags and Kent's Cavern. The implements obtained from the two lower strata are rough choppers and rude flakes of jasper and other simple forms. Above these beds was a stratum of black earth, underneath a sheet of stalagmite. Here were found implements of a far higher type: those of flints, consisting of flakes, saws, and scrapers, with finely chipped heads and arrowheads, and awls and arrowheads of bone and antler. Now these results can only be interpreted as were those in the English caverns. The lower and ruder implements belong to the men of the Drift; the later and more polished ones to the Cavemen. Illustration of Bone Implements, Dordogne Caves.------------- Most of the relics obtained from these caverns belong to the Cavemen proper. However, the implements from one of them, known as Le Moustier, are of a rude type, and may belong to those of the Drift. But most of them are of superior make and finish. These specimens are all from caves in this vicinity. We have seen that the men of the Drift were very widely scattered over the earth. We find, however, that the Cavemen had a much more limited range. Dr. Fraas has shown their presence in Germany. At Schussenreid, in Bavaria, was found an open air station of these people. It was evidently a camping-ground, one of the few places where proofs of their 120 presence have been discovered outside of caves. Here we found the usual debris, consisting of broken bones, charcoal, blackened hearth-stone, and implements of flint and horn. We must stop a minute to notice a bit of unexpected proof as to the severity of climate then prevailing in Europe. This deposit was covered up with sand, and on this sand were the remains of moss, sufficiently perfect to determine the kind. We are assured that it is composed of species now found only in Alpine regions, near or above the snow-line, and in such northern countries as Greenland and Spitzbergen. Dr. Fraas also proved their presence in several caves in Suabia. One known as the Hohlefels Cave was very rich in these relics. They have been found in Switzerland, as at Thayengen; but are not found south of the Alps or the Pyrenees. Men, indeed, inhabited caves in Italy, but they did not use the implements characteristic of the Cavemen. Mr. Dawkins points out that this range corresponds very nearly to that of the northern group of animals, thus differing widely from the men of the River Drift. In this connection we must notice that the reindeer is the animal whose remains are most commonly met with in the debris they have left in the caves. This animal surely testifies to a cold climate. We are thus justified in concluding that the Cavemen are associated with the Arctic group of animals. We must now turn our attention to the culture of the Cavemen. We must reflect that long ages, with great changes of climate and life, both animal and vegetable, have rolled away since the remains of these early races were sealed by the stalagmite formation in caves. The relics at their best are but scanty memorials of a people long since passed, and we can not expect, can not hope, to recover more than a general outline. But this will be found full of interest, for it is a picture of Paleolithic life and times existing in Europe long ages before the 121 pyramids of Egypt were uplifted. With respect to habitations, we have already seen that he took up his abode in caves, at least where they were suitable. According to their depth and the light penetrating them, he either occupied the whole extent of them, or established himself in the outlet only. About the center of the cave some slabs of stone, selected from the hardest rock such as sandstone or slate, were bedded down in the ground, and formed the hearth for cooking his food. But in no country are such resorts sufficiently numerous to shelter a large population; besides, they, are generally at some distance from the fertile plains, where game would be most abundant. In such cases they doubtless constructed rude huts of boughs, skins, or other materials. Such an out-door settlement was the station at Solutre, France, where has been found an immense number of bones of horses, reindeers, also, though in less abundance, those of elephants, aurochs, and great lions. Where no cave presented itself, these people made for themselves convenient sheltering places under the cover of some great overhanging rock. In various places in France such resorts have been discovered. The name of "rock shelters" has been given to such resorts. In such places, where we may suppose they built rude huts, are found rich deposits of the bones of mammals, birds, and fishes, as well implements of bone and horn. We have frequently referred to the presence of hearths, showing that they used fire. Like other rude races, it is probable that they obtained fire by the friction of one piece of wood upon another. M. Dupont found in one of the Belgium caves a piece of iron pyrites, from which, with a 122 flint, sparks could be struck. Speculations have been indulged as to the probable condition of man before he obtained a knowledge of fire. If the acquisition of fire be regarded as one of the results of human endeavor, it must surely be classed as one of the most valuable discoveries which mankind has made. We do not believe, however, that we shall ever discover relics of races or tribes of men so low in the scale as to be ignorant of the use of fire. Even some of the flints which M. Bourgeois would refer to the Miocene Age show evidence of its action. Full-page picture of Rock Shelter at Bruniquel.----------- The men of the Caves supported life by hunting. But a very small part of their food supplies could have been drawn from the vegetable kingdom. When the climate was so severe that Alpine mosses grew at Schussenreid, acorns and like nuts would be about all they could procure from that source. The animals hunted by the Cavemen were principally reindeer, horses, bisons, and, occasionally mammoths and woolly rhinoceros. But they were not very choice in this matter, as they readily accepted as food any animal they could obtain by force or cunning. Wolves and foxes were not rejected, and in one cave large numbers of the bones of the common water rat were obtained. We know what animals were used as food, because we find their bones split for the purpose of procuring the marrow they contained. This was evidently to them a nutritious article of diet, since they were careful to open all the bones containing it, and bones so split are frequently the only means of detecting the former 123 presence of man in some bone caves. We must not forget that at that time the shore of the Atlantic Ocean, during a large part of the Paleolithic Age, was situated much farther west than it is now, and so in all probability many refuse heaps are now underneath the waves. From certain drawings that are found in some French caves, we know they were used for hunting both seals and whales. We can not doubt that the capture of a whale afforded as much enjoyment to them as it does to a tribe of Eskimos now. Bones of birds and fishes are found in many instances. The salmon appears to have been a favorite among fishes. Among the birds are found some species now only living in cold countries, such as the snowy owl, willow grouse, and flamingo. This is but another proof that the climate of Europe was then very cold. Illustration of Whale and Seal, Incised on Bone.------------ The Cavemen were not afraid to attack animals greatly superior to them in strength. In the Hohlefels Cave in Germany were found great quantities of the broken and split bones of cave bears, an animal very similar to the grizzly, and probably its equal in strength. The reindeer was the main reliance of these tribes. Its bones are found in great abundance, and it doubtless was to them all it is to the Lapps of Europe to-day, except, of course, that it was not domesticated. Though fire would naturally suggest some rude method of cooking, we can scarcely find a trace of such operations, and it has been a matter of conjecture how they proceeded. Sir John Lubbock thinks they boiled 124 their food, and in the absence of pottery used wooden or skin vessels, bringing the water to a boiling point by means of stones heated red hot and thrown into the water. He points out the presence of peculiarly shaped stones found in some caves, which he thinks were used for this purpose. It is not supposed they had any articles of pottery during this epoch. This is quite an important point, because a knowledge of pottery marks an important epoch in the culture of a people. Illustration of Cave Bear, Incised on Slate.----------------- A people possessed of this knowledge have passed from Savagism into the lower status of Barbarism. A piece of pottery is as little liable to destruction as a piece of bone, and so, had those people possessed pottery, there is no reason why pieces of it should not be found in every refuse heap, and amongst the debris of all caves. But such is not the case; no fragments of pottery have yet been found which can be referred with confidence to the epoch of the Cavemen. Some speculations have been indulged in as to whether the men of this age were cannibals or not. It need occasion no surprise if they were, since ancient writers assert that even during historical times this practice prevailed in Europe. Though not definitely proven there are many facts difficult of explanation, except on this supposition. However, it may well be that this, after all, only amounted to the custom of eating parts of an enemy killed in battle, as certain modern savages do that we would not call cannibals. 125 It is not necessary to speak at much length of the methods of hunting. They had bows and arrows, daggers of reindeer horn, spears tipped with flint or bone, and harpoons. Besides, they made a formidable club of the lower jaw-bone of the cave-bear with its canine tooth still left in its place. Fishing with nets is not supposed to have been known, Harpooning was probably their favorite way. M. G. DeMortillet thinks they fished as follows: They fastened a cord to the middle of a small splinter of bone. This was then baited, and when swallowed by the fish, was very certain to get caught in the body. We know that rude tribes of to-day have many means of snaring animals. Doubtless similar scenes were enacted on their primeval hunting-grounds. French books contain illustrations of the men of this period driving game over precipitous sides. They had no dogs to assist them in the hunt, and though reindeer were around them in great abundance, it is not supposed that they thought of domesticating them. Man is the only animal which seeks to protect his body from the Summer's heat or the cold of Winter by the use of clothing. We are, unfortunately, not able to present many details of the dress of man during the early Stone Age. We are, however, quite certain that when the climate was severe enough to permit such animals as the musk-sheep and the reindeer to inhabit Southwestern Europe, man must have been provided with an abundance of warm clothing, though doubtless rudely made and fashioned. Many reindeer horns found in France are cut and hacked at the base in such a way as to indicate that it was done when removing the skins. We also know that the rudest of savage tribes are never at a loss for some process of tanning hides and rendering them fit for use. From the immense number and variety of scrapers found among 126 the cave debris. we are sure the preparation of clothing occupied no inconsiderable portion of their time. We also find numerous awls and splinters of flint and bone, which they doubtless used in exactly the same manner as similar tools are used by the Lapps to-day in Europe, that is, to pierce holes in the hides, through which to pass their rude needle and thread. The needles are made of reindeer horn, and they were not only smoothly polished, but the eyes are of such a minute size, and withal so regularly made, that many at first could not believe they were drilled by the use of flint alone. This, however, has been shown to be the case by actual experiments. The thread employed was reindeer tendons, for bones of these animals are found cut just where they would he cut in removing these tendons. This cut shows that they protected their hands by means of long gloves of three or four fingers. Illustration of Glove, Incised on Bear's Tooth.----------- We have thus far been considering those arts which pertain more directly to living. We have presented some sketches found engraved on pieces of bone. We first noticed this among the relics found in one of the Creswell caves in England. It was also noticed in Belgium. It was among the Cavemen of Southern France that this artistic trait became highly developed. Among the reindeer hunters of the Dordogne were artists of no mean ability. We must pause a minute and mark the bearing of this taste for art. We have seen many reasons for supposing the men of the caves much farther advanced in the scale of culture than those of the Drift, but we have also seen that we can not rank them higher than the highest grade of savages. 127 Sir John Lubbock thus speaks of them: "In considering the probable condition of these ancient Cavemen, we must give them full credit for their love of art, such as it was; while, on the other hand, the want of metal, of polished flint implements, and even of pottery, the ignorance of agriculture, and the apparent absence of all domestic animals, including even the dog, certainly imply a very low state of civilization." They were certainly not as far advanced in civilization as the next race we will describe, yet the Neolithic people had no such skill as was possessed by the cave-men. This need not surprise us, because "an artistic feeling is not always the offspring of civilization, it is rather a gift of nature. It may manifest its existence in the most barbarous ages, and may make its influence more deeply felt in nations which are behind in respect to general progress than in others which are more deeply advanced in civilization." Illustration of Reindeer Grazing.------------- In regard to the objects themselves, a glance at the illustrations show us that they are quite faithful sketches of the animals at that time common. As might be expected, sketches of the reindeer are numerous. This cut is regarded as the highest example of Paleolithic art, sketched on a piece of horn and found in Switzerland. The animal is grazing, and the grass on which it feeds is seen below. We have on a piece of slate the outlines of a group of reindeer, generally considered as 128 representing a fight, though it may mean a hunt, and that the hunter has succeeded in killing a portion of the herd. Some, as we see, are on the ground. Illustration of a Group of Reindeers.--------- Illustration of Man and Other Animals.-------- It would be exceedingly interesting could we but find well executed sketches of the men of this period, but, unfortunately, with one or two exceptions, no representations, however rude, have yet been discovered of the human form. Perhaps an explanation of this fact may be found in the well-known reluctance of savage tribes to have any engravings taken of themselves, and we can well imagine that if any one was known to make drawings of human beings he would be regarded with suspicious distrust, and it would hardly be a safe accomplishment to possess. One very curious group represents a man, long and lean, standing between two horses' heads, and by the side of a long serpent or fish, having the appearance of an eel. On the reverse side of this piece of horn were represented the heads of two aurochs or bisons. Mr. Dawkins thinks this also represents a hunting sketch, and that the man is in the act of striking one of the horses with a spear. Illustration of Fish, Incised on Bear's Tooth.------------ 129 Illustration of Ibex.------------------ On, a fragment of spear-head found in France several human hands were engraved, but having only four fingers each. On this point Mr. Lartet assures us that some savage tribes still depict the hand without the thumb. Representations of birds and reptiles are very rare; fishes are more common. On a piece of reindeer's horn was found this representation of the head and chest of an ibex. Of special interest to us is a representation of a mammoth found engraved on a piece of mammoth tusk in one of the Dordogne caves. We have no doubt that the artist who engraved it was perfectly familiar with the animal itself. Illustration of Mammoth--La Madeline Cave, France.---------- Their artistic skill was not confined to the execution of drawings. They frequently carved pieces of reindeer horn into various animal forms. Our next cut shows us a dagger, the handle of which is carved to imitate a reindeer. It will be seen how the artist has adapted the position of the animal to the necessities of the case. Flowers are very seldom represented; but one implement from France has a very nice representation of some flowering plant engraved on it. Take it all in all, the possession of this artistic instinct is certainly remarkable--the more so when we remember the rudeness of his surroundings, and the few and simple means at his command for work. "A 130 splinter of flint was his sole graving tool; a piece of reindeer horn, or a flake of slate or ivory, was the only plate on which primitive man could stamp his reproduction of animated nature." Illustration of Reindeer Carved on Dagger Handle.------- Some speculations have been indulged in as to whether we have any traces of a government amongst the Paleolithic people. That they had some chief or leader is more than probable. In the caves of France we find a number of fragments of reindeer horn. Generally speaking, they show evidence of a good deal of care in making them. They are carved and ornamented with sketches of various animals, and invariably have one or more holes bored in the base. The idea has been quite freely advanced, that these are emblems of authority. And some have pointed out, that, though they are too light for use as weapons, yet, their "frequent occurrence, and uniformity of type, show that they possess a conventional significance." Mr. Geikie says that these conjectures "are mere guess-work." And Mr. Dawkins points out that they are very similar in design and ornament with an implement of the Eskimos known as an "arrow-straightener." Whatever may be our conclusions in regard to these ornamented pieces of reindeer horn, we can not doubt but that their social instincts found expression in some sort of alliance for the common good. This is shown by several facts: such, for instance, as the evidence of trade or barter between localities considerable distances apart. The inhabitants of Belgium must have gone to what is now Southern France to procure the 131 flint they used. They also procured, from the same source, fossil sea-shells, which they valued highly. We also notice the fact, that certain localities appear to have been used as the place of manufacture for certain articles, to the exclusion of others. In other words, the primitive people appear to have learned the great utility of a division of labor. One of the caves in Belgium appears to have been used as a place to make flint implements. Over twenty thousand articles of flint were found in this cave. In France, while in one cave the implements were all of the spear-head type, in a neighboring cave horn was almost the only article used in the manufacture of implements. We must not, however, form an exalted idea of their trade--it was simply barter in a rude state of society. Illustration of Flowers on Reindeer's Horn.-------- Various opinions have been held as to whether we have any trace of a religious belief. Theoretically speaking, they had some sort of a religion, though doubtless very vague and indistinct; for we know of no nation as far advanced as they were destitute of it. It has been pointed out, that the bones of some animals, as the horse, were very rare, and their absence explained as the result of superstitious reasons. It has also been conjectured that some of the perforated bones and teeth of animals found in various deposits were amulets worn for religious purposes; and some have gone so far as to infer, that the ornamentations on some of these so-called amulets represent the sun, and that, consequently, sun-worship prevailed among the Cavemen. While these various conjectures are, of course, possible, it is equally 132 certain they are all "mere guess-work." Illustration of Ornamented Reindeer Horn--------------- Early explorers describe with considerable degree of confidence the manner of burial among the Cavemen, and inferred from the remains found buried with the bodies that they had some notion of a life beyond the grave--and, accordingly, placed near the body food and drink to support him on his journey, weapons wherewith to defend himself, and his favorite implements, so that, arrived at the land of spirits, he would be well provided for. These result are not borne out by later investigations. The instance mentioned most prominently, that of the burial cave at Aurignac, France, has been shown to have no bearing on the question, as every thing indicates that the burials were of a much later date. We have yet a most important question before us--one that is still engaging the attention of scientific men in Europe. That is the question of race. Who were these early tribes? Are they in any way connected with the men of the Drift? Have we any representations of them now living upon the earth? On these questions there is quite a diversity of opinion. In various caves in France and Belgium, skulls and other bones of the human skeleton have been found. These have been studied with care by the best scholars in Europe; and B. Carfares has set forth the results in his various works, in which he connects them, not only with the men of the River Drift, but with the race of men that inhabited Europe during the succeeding Neolithic Age, and, indeed, with men now 133 living in France and Belgium. There is no question as to the correctness of these inferences--the only one is, whether the skulls and fragmentary skeletons are really remains of the Cavemen. This must be made perfectly clear and unquestioned before we are to accept them. Mr. Darkens reviews the various cases where skeletons have been found in caves. He points out that, in every instance, very serious doubts can be raised as to whether they are really remains of the Cavemen or not. Until these objections are met, we do not see how the opinion of B. Carfares (above) can be accepted. But if these instances are not accepted, then, in all other instances where there is no doubt, the remains are in such a fragmentary condition that no conclusion can be made from them. So as far as remains of the human skeleton are concerned, we can form no conclusions as to the race to which the Cavemen belonged. We have already noted, that the Cavemen came into Europe much later than the men of the Drift, and that their range was very limited, corresponding, in fact, with that of the northern group of animals. When the cold of the Glacial Age passed away, the musk-sheep, reindeer, and other animals, were driven out of Europe. They are found now only in high northern latitudes, such as Greenland. Mr. Darkens thinks that there, also, are to be found the Cavemen of the Paleolithic Age, now known as the Eskimos. Though not accepted by all authorities, yet some of our best scholars find much to commend in this theory. We have undoubted proofs that, in America, the Eskimos formerly lived 134 much farther south. And Dr. Abbot thinks the Paleolithic implements discovered in New Jersey, bearing such striking resemblance to those of Europe, are undoubtedly their work. Therefore, there is no absurdity in asserting that they once lived in Western Europe; the more so, when we reflect that the climate, the animals--in fact, all their surroundings--must have been similar to those of their present habitats. When we come to examine the customs and habits of these Eskimos, we are at once struck with their resemblance to what we have seen was the probable state of life among the Cavemen. At Solute, for instance, we have vast refuse heaps of bones of animals. We find similar heaps around the rude huts of the Eskimos to-day. Captain Parry describes one as follows: "In every direction round the huts were lying innumerable bones of walruses and seals, together with skulls of dogs, bears, and foxes." Other points of comparison strike us when reading Sir John Lubbock's account of their habits and customs. For instance: "Their food, if cooked at all, is broiled or boiled; their vessels, being of stone or wood, can not, indeed, be put on the fires, but heated stones are thrown in until the water becomes hot enough and the food is cooked." "Their food consists principally of reindeer, musk-ox, walrus, seals, birds, and salmon. They will, however, eat any kind of animal food. They are very fond of fat and marrow, to get at which they pound the bones with a stone." "The clothes of the Eskimos are made from the skins of the reindeer, seals, and birds, sewn together with sinews. For needles they use the bones of either birds or fishes." "The Eskimos have also a great natural ability for drawing. In many cases they have made rude maps for our officers, which have turned out to be substantially correct. Many of 135 their bone implements are covered with sketches." Illustration of Eskimo Art.----------- In this cut we have a bone drill on which are sketched reindeer, geese, a braider or flat-bottomed boat, a tent around which various articles of clothing are hung up to dry, a woman apparently engaged in the preparation of food, and a hunting scene. Now, we know that savage tribes, widely separated by time and space, will, after all, under the pressure of common necessities, invent much the same implements and live much the same life. But still, where every thing seems to coincide, the climate, the animals, the mode of life proved the same, and especially when both are seen possessed of a common artistic skill, together with the known fact that in the Western Continent the Eskimos did formerly live much farther south; there is surely a strong case made out, and therefore the probabilities are that the Eskimos are the representatives of the Cavemen of Europe. And yet we must be cautious on this point; or rather we remember that the phrase, "predecessors of the Eskimos," does not imply that they were in all respects like them. An examination of the rude sketches of the Cavemen left by themselves seems to indicate that the whole body was covered with hair. "The hunter in the Antler from Duluth Cave has a long, pointed beard, and a high crest of hair on the poll utterly unlike the Eskimo type. The figures are also those of a slim and long-jointed man." 136 This completes our review of the Paleolithic people, and it only remains to present some general conclusions. The Glacial or Pleistocene Age is seen to have been of immense duration, and characterized by great changes in climate. We have found that two races of men occupied Europe during this time. The men of the River Drift are the most ancient. We have seen that they can be traced over wide-extended areas. They seem to have invaded Europe, along with the great invasion of animals from Asia, constituting the temperate group of animals; and with those animals they probably shifted back and forth, as the cold of the Glacial Age increased or waned. These people seem to have completely vanished. At a later date, when the cold of the Glacial Age was once more severe, associated with animals now living only in high northern latitudes, came the Cavemen, whose discussion has formed the subject of this chapter. It will be seen how much we owe to patient investigators. The results are, indeed, bewildering. They make us acquainted with a people the very existence of whom was not known a few years back. Though the whole life of those ancient races seemed hopelessly lost in the night of time, the gloom is irradiated by the light of modern science, which lays before our astonished vision the remains of arts and industries of the primitive tribes that occupied Europe during the morning-time of human life.

He considers them to be the remains of the same people, some tribes being, perhaps, farther advanced than others. Mr. Dawkins is, of course, high authority, but we think his argument could also be applied to prove there was no real difference between the men of the River Drift and the so-called Cavemen. This, in fact, is the opinion of many, including Mr. Evans, who is exceptionally well qualified to judge of these remains. We think, however, in view of the evidence adduced by Mr. Pengelly, Mr. Geikie, Mr. Dawkins, and others, few will venture to doubt that there is a wide difference between the men of the River Drift and those of the Caves.

To say that man lived in the Glacial Age, and that we have some faint traces of his presence in still earlier periods, after all conveys to our minds only vague ideas of a far-away time. The more a geologist studies the structure of the earth, the more impressed is he with the magnitude of the time that must have passed since "The Beginning." At present, however, there are no means known of accurately measuring the time that has passed. It is just as well that it is so, since, were it known, the human mind would be utterly incapable of comprehending it. But as to the antiquity of man, it is but natural that we should seek more particularly to solve the problem and express our answer in some term of years. Now, we have seen that the question of the antiquity of man is intimately connected with that of the Glacial Age. That is to say, the relics of man as far as we know them in Europe, are found under such circumstances that we feel confident they are not far removed from the period of cold. For it will be found that those conservative scholars who do not think that man preceded the Glacial Age, or inhabited Europe during the long course of years included in that period, do think he 141 came into Europe as soon as it passed away. So, in any case, if we can determine the date of the Glacial Age, we shall have made a most important step in advance in solving the problem of the antiquity of man himself. So it seems to us best to go over the subject of the Glacial Age again, and see what conclusions some of our best thinkers have come to as to its cause, when it occurred, and other matters in relation to it. It is best to state frankly at the outset that this topic is one of the great battle-grounds of science to-day, and that there are as yet but few points well settled in regard to it. One needs but attempt to read the literature on this subject to become quickly impressed with the necessity of making haste slowly in forming any conclusions. He must invoke the aid of the astronomer, geologist, physical-geographer, and physicist. Yet we must not suppose that questions relating to the Glacial Age are so abstruse that they are of interest only to the scholar. On the contrary, all ought to be interested in them. They open up one of the most wonderful chapters in the history of the world. They recall from the past a picture of ice-bound coasts and countries groaning under icy loads, where now are harbors enlivened by the commerce of the world, or ripening fields attesting the vivifying influence of a genial sun. Let us, therefore, follow after the leaders in thought. When we come to where they can not agree we can at least see what both sides have to say. Somewhat at the risk of repetition, we will try and impress on our readers a sense of the reality and severity of the Glacial Age. There is danger in regarding this as simply a convenient theory that geologists have originated to explain some puzzling facts, that it is not very 142 well founded, and is liable to give way any day to some more ingenious explanation. On the contrary, this whole matter has been worked out by very careful scholars. There is, perhaps, no great conclusion in any science which rests upon a surer foundation than this, and if we are to be guided by our reason at all in deducting the unknown from the known, the past from the present, we can not refuse our assent to the reality of the Glacial Age of the Northern Hemisphere in all its more important features. At the present day glaciers do exist in several places on the earth. They are found in the Alps and the mountains of Norway, and the Caucasus, in Europe. The Himalaya mountains support immense glaciers in Asia; and in America a few still linger in the more inaccessible heights of the Sierra Nevada. It is from a study of these glaciers, mainly however, those of the Alps, that geologists have been enabled to explain the true meaning of certain formations they find in both Europe and America, that go by the name of drift. When in an Alpine valley we come upon a glacier, filling it from side to side, there will be noticed upon both sides a long train of rock, drift, and other debris that have fallen down upon its surface from the mountain sides. If two of these ice-rivers unite to form one glacier, two of these trains will then be borne along in the middle of the resulting glacier. As this glacier continues down the valley, it at length reaches a point where a further advance is rendered impossible by the increased temperature melting the ice as fast as it advances. At this point the train of rocks and dirt are dumped, and of course form great mounds, called moraines. The glacier at times shrinks back on its rocky bed and allows explorers to examine it. In such cases they find the rocks smoothed and polished, but here and 143 there marked with long grooves and striae. These points are learned from an examination of existing glaciers. Further down the valley, where now the glaciers never extend, are seen very distinctly the same signs. There are the same moraines, striated rocks, and bowlders that have evidently traveled from their home up the valley. The only explanation possible in this case is that once the glaciers extended to that point in the valley. It required a person who was perfectly familiar with the behavior of Alpine glaciers, and knew exactly what marks they left behind in their passage, to point out the proofs of their former presence in Northern Europe and America, where it seems almost impossible to believe they existed. Such a man was Louis Agassiz, the eminent naturalist. Born and educated in Switzerland, he spent nine years in researches among the glaciers of the mountains of his native country. He proved the former wide extension of the glaciers of Switzerland. With these results before them, geologists were not long in showing that there had once been glacial ice over a large part of Europe and North America. The proofs in this case are almost exactly the same as those used to show that the ancient glaciers of Switzerland were once larger than now. But as the great glaciers of the glacial age were many times larger than any thing we know of at the present day, there were of course different results produced. For instance, the water circulating under Alpine glaciers is enabled to wash out and carry away the mass of pulverized rock and dirt ground along underneath the ice. But when the glaciers covered such an enormous extent of country as they did in the Glacial Age, the water could not 144 sweep away this detritus, and so great beds of gravel, sand, and clay would be formed over a large extent of country. But to go over the entire ground would require volumes; it is sufficient to give the results. The interior of Greenland to-day is covered by one vast sea of ice. Explorers have traversed its surface for many miles; not a plant, or stone, or patch of earth is to be seen. In the Winter it is a snow-swept waste. In the Summer streams of ice-cold water flow over its surface, penetrating here and there by crevasses to unknown depths. This great glacier is some twelve hundred miles long, by four hundred in width. Vast as it is, it is utterly insignificant as compared with the great continental glacier that geologists assure us once held in its grasp the larger portion of North America. The conclusions of some of our best scholars on this subject are so opposed to all that we would think possible, according to the present climate and surroundings, that they seem at first incredible, and yet they have been worked out with such care that there is no doubt of the substantial truth of the results. The terminal moraine of the great glacier has been carefully traced through several States. We now know that one vast sea of ice covered the eastern part of North America, down to about the thirty-ninth parallel of latitude. We have every reason to think that the great glacier, extending many miles out in the Atlantic, terminated in a great sea of ice, rising several hundred feet perpendicularly above the surface of the water. Long Island marks the southern extension of this glacier. From there its temporal moraine has been traced west, across New Jersey 145 and Pennsylvania, diagonally across Ohio, crossing the river near Cincinnati, and thence west across Indiana and Illinois. West of the Mississippi it bears off to the northwest, and finally passes into British America. All of North America, to the north and northeast of this line, must have been covered by one vast sea of ice. Doubtless, as in Greenland to-day, there was no hill or patch of earth to be seen, simply one great field of ice. The ice was thick enough to cover from sight Mt. Washington, in New Hampshire, and must have been at least a mile thick over a large portion of this area, and even at its southern border it must in places have been from two hundred to two thousand feet thick. This, as we have seen, is a picture very similar to what must have been presented by Europe at this time. Illustration of Antarctic Ice Sheet.----------------- The Northern Atlantic Ocean must have presented a dreary aspect. Its shores were walls of ice, from which ever and anon great masses sailed away as icebergs. These are startling conclusions. Yet, in the Southern Hemisphere to-day is to be seen nearly the same state of things. It is well-known that all the lands around the South Pole are covered by a layer of ice of enormous thickness. Sir J. A. Ross, in attempting to reach high southern latitudes, while yet one thousand four hundred miles from the pole, found his further progress impeded by a perpendicular wall of ice one hundred and eighty feet thick. He sailed along that barrier four hundred and fifty miles, and then gave up the attempt. Only 146 at one point in all that distance did the ice wall sink low enough to allow of its upper surface being seen from the mast-head. He describes the upper surface as an immense plain shining like frosted silver, and stretching away as far as eye could reach into the illimitable distance. The foregoing makes plain to us one phase of the Glacial Age. Though it may not be quite clear what this has to do with the antiquity of man, yet we will see, in the sequel, that it has considerable. As to the periods of mild climate that are thought by some to have broken up the reign of cold, we do not feel that we can say any thing in addition to what has been said in a former chapter. We might, however, say, that the sequences of mild and cold climate are not as well made out in America as they seem to be in Europe; or at least our geologists are more cautious as to accepting the evidence as sufficient. And yet such evidences are not wanting: as in Europe, at various places, are found layers of land surfaces with remains of animals and plants, but both above and below such surface soil are found beds of bowlder clay. These offer undeniable evidence that animals and plants occupied the land during temperate interglacial epochs, preceded and followed by an Arctic climate, and ice-sheets like those now covering the interior of Greenland, and the Antarctic Continent. We have thus, though somewhat at length, gone over the evidence as to the reality and severity of the Glacial Age. It was during the continuance of such climate that Paleolithic man arrived in Europe, though it was not perhaps until its close. We must not lose sight of the fact that our principal object at present is to determine, if we can, a 147 date for either the beginning or ending of this extraordinary season of cold, and thereby achieve an important step in determining the antiquity of man. A moment's consideration will show us that a period of cold sufficient to produce over a large portion of the Northern Hemisphere the results we have just set forth must have a cause that is strange and far-reaching. It can not be some local cause, affecting but one continent, since the effect produced is observed as well in Europe as in America. Every year we pass through considerable changes in climate. The four seasons of the year seem to be but an annual repetition, on a very small scale of course, of the great changes in the climate of the earth that culminated in the Glacial Age; though we do not mean to say, that periods of glacial cold come and go with the regularity of our Winter. The changes in the seasons of the year are caused by the earth's position in its orbit, and its annual revolution around the sun. It may be that the cause of the Glacial Age itself is of a similar nature; in which case it is an astronomical problem, and we ought, by calculation, to determine, with considerable accuracy, dates for the beginning and ending of this epoch. Nothing is clearer than that great fluctuations of climate have occurred in the past. Many theories have been put forth in explanation. It has been suggested that it was caused by loss of heat from the earth itself. That the earth was once a ball of incandescent matter, like the sun, and has since cooled down, is of course admitted. More than that, this process still continues; and the time must come when the earth, having 148 yielded up its internal heat, will cease to be an inhabitable globe. But the climate of the surface of the earth is not dependent upon the heat of the interior. This now depends "according to the proportion of heat received either directly or indirectly from the sun; and so it must have been during all the ages of which any records have come down to us." Some have supposed that the sun, traveling as it does through space, carrying the earth and the other planets with him, might, in the course of ages, pass through portions of space either warmer or colder than that in which it now moves. When we come to a warm region of space, a genial climate would prevail over the earth; but, when we struck a cold belt, eternal Winter would mantle a large part of the globe with snow and ice. This, of course, is simply guess-work. No less than seven distinct causes have been urged; most of them either purely conjectural, like the last, or manifestly incompetent to produce the great results which we have seen must be accounted for. But, amongst these, two causes have been advanced--the one astronomical, the other geographical; and, to the one or the other, the majority of scholars have given their consent. It will be no harm to see what can be said in favor of both theories. So, we will ask the reader's attention, as it is our earnest desire to make as plain as possible a question that has so much to do with our present inquiry. In the course of our investigations, we can not fail to catch glimpses of wonderful changes in far away times; and can not help seeing what labor is involved in the solution of all questions relating to the same. The earth revolves around the sun in an orbit called an ellipse. This is not a fixed form, but slowly varies from year to year. It is now 149 gradually becoming circular. It will, however, not become an exact circle. Astronomers assure us that, after a long lapse of time, it will commence to elongate as an ellipse again. Thus, it will continually change from an ellipse to an approximate circle, and back again. In scientific language, the eccentricity of, the earth's orbit is said to increase and decrease. Illustration of Earth's Orbit.-------------------- In common language we would state that the shape of the path of the earth around the sun was sometimes much more elongated and elliptical than at others. The line drawn through the longest part of an ellipse is called the major axis. Now the sun does not occupy the center of this line, but is placed to one side of it; or, in other words, occupies one focus of the ellipse. It will thus be seen that the earth, at one time during its yearly journey, is considerably nearer to the sun than at others. The point where it approaches nearest the sun is called _Perihelion,_ and the point where it reaches the greatest distance from the sun is called its Aphelion. It will be readily seen that the more elliptical its orbit becomes the greater will be the difference between the perihelion and aphelion distance of the sun. At present the earth is about three millions of miles nearer the sun in perihelion than in aphelion. But we must remember the orbit of the earth is now nearly circular. There have been times in the past when the difference was about thirteen millions of miles. We must not forget to add, that the change in the shape of the earth's orbit is not a regular increase and decrease between well-known extremes. It is caused by the attraction of 150 the other planets. It has been calculated at intervals of ten thousand years for the last million years. In this way it has been found that "the intervals between connective turning points are very unequal in length, and the actual maximum and minimum values of the eccentricity are themselves variable. In this way it comes about that some periods of high eccentricity have lasted much longer than others, and that the orbit has been more elliptical at some epochs of high eccentricity than at others." We have just seen that the earth is nearer the sun at one time of the year than at another. At present the earth passes its perihelion point in the Winter of the Northern Hemisphere, and its aphelion point in the Summer. We will for the present suppose that it always reaches the points at the same season of the year. Let us see if the diminished distance from the sun in Winter has any thing to do with the climate. If so, this effect will be greatly magnified during a period of high eccentricity, such as the earth has certainly passed through in the past. We will state first, that the more elliptical the orbit becomes, the longer Summer we have, and the shorter Winter. Astronomically, Spring begins the 20th of March, and Fall the 22d of September. By counting the days between the epochs it will be found that the Spring and Summer part of the year is seven days longer than the Fall and Winter part. But if the earth's orbit becomes as highly eccentrical as in the past, this difference would be thirty-six days. This would give us a long Spring and Summer, but a short Fall and Winter. This in itself would make a great difference. We must beer in mind, however, that at such a time as we are here considering, the earth would be ten millions of miles nearer the sun in Winter than at present. 151 It would certainly then receive more heat in a given time during Winter than at present. Mr. Croll estimates that whereas the difference in heat received during a given time is now one-fifteenth, at the time we are considering it would be one-fifth. Hence we see that at such a time the Winter would not only be much shorter than now, but at the same time would be much milder. These are not all the results that would follow an increase of eccentricity. The climate of Europe and North America is largely modified by those great ocean currents--the Gulf Stream and the Japan current. Owing to causes we will not here consider, these currents would be greatly increased at such a time. As a result of these combined causes, Mr. Croll estimates that during a period of high eccentricity the difference between Winter and Summer in the Northern Hemisphere would be practically obliterate. The Winter would not only be short, but very mild, and but little snow would form, while the sun of the long Summers, though not shining as intense as at present, would not have to melt off a great layer of snow and ice, but the ground became quickly heated, and so warmed the air. Hence, if Mr. Croll be correct, a period of high eccentricity would certainly produce a climate in the Northern Hemisphere such as characterized many of the mild interglacial epochs as long as the earth passed its perihelion point in Winter. We have so far only considered the Northern Hemisphere. As every one knows, while we have Winter, the Southern Hemisphere has Summer. So at the very time we would enjoy the mild short Winters, the Southern Hemisphere would be doomed to experience Winters of greatly increased length and severity. As a consequence, immense fields of snow would be formed, which, by pressure, would be changed to ice, and creep away as 152 a desolating glacier. It is quite true that the short Summer sun would shine with increased warmth, but owing to many causes it would not avail to free the land from snow and ice. As Mr. Geikie points out, "An increased amount of evaporation would certainly take place, but the moisture-laden air would be chilled by coming into contact with the vast sheets of snow, and hence the vapor would condense into thick fogs and cloud the sky. In this way the sun's rays would be, to a large extent, cut off, and unable to reach the earth, and consequently the Winter's snow would not be all melted away." Hence it follows that at the very time the Northern Hemisphere would enjoy a mild interglacial climate, universal Spring, so to speak, the Southern Hemisphere would be encased in the ice and snow of an eternal Winter. But the earth has not always reached its perihelion point during the Winter season of the Northern Hemisphere. Owing to causes that we need not here consider, the earth reaches its perihelion point about twenty minutes earlier each year, so if it now passes its perihelion in Winter of the Northern Hemisphere, in about ten thousand years from now it will reach it in Summer, and in twenty-one thousand, years it will again be at perihelion in Winter. But see what important consequences follow from this. If during a period of high eccentricity we are in the enjoyment of short mild Winters and long pleasant Summers, in ten thousand years this would certainly be changed. Our Summer season would become short and heated; our Winters long and intensely cold. Year by year it would be later in the season before the sun could free the land from snow, and at length in deep ravines and on hill-tops the snow would linger through the brief Summer, and the mild interglacial age will have passed away, 153 and again the Northern Hemisphere will be visited by snow and ice of a truly. Glacial Age. If, therefore, a period of high eccentricity lasts through the many thousand years, we must expect more than one return of glacial cold interspersed by mild interglacial climates. We have tried in these last few pages to give a clear statement of what is known as Croll's theory of the Glacial Age. There is no question but what the earth does thus vary in its position with regard to the sun, and beyond a doubt this must produce some effect on the climate, and we can truthfully state that the more the complicated question of the climate of the earth is studied, the more grounds do scholars find for affirming that indirectly this effect must have been very great. And yet we can not say that this theory is accepted as a satisfactory one even by the majority of scholars. Many of those who do not reject it think it not proven. Therefore, before interrogating the astronomer as to the data of the Glacial Age, according to the terms of this theory, let us see what other causes are, adduced; then we can more readily accept or reject the conclusions as to the antiquity of man which this theory would necessitate us to adopt. The only other cause to which we can assign the glacial cold, that is considered with any favor by geologists, is geographical; that is to say, depending on the distribution of land and water. Glaciers depend on the amount of snowfall. In any country where the amount of snowfall is so great that it is not all evaporated or melted by the Summer's sun, and consequently increases from year to year, glaciers must soon appear, and these icy rivers would ere-long, flow away to lower levels. If we suppose, with Sir Charles Lyell, that the lands of the globe were all to be gathered around the equator, and the waters were gathered around the 154 poles, it is manifest that there would be no such a thing as extremes of temperature, and it is, perhaps, doubtful whether ice would form, even in polar areas. At any rate, no glaciers could be formed, as there would be no land on which snow could gather in great quantities. If, however, we reverse this picture, and conceive of the land gathered in a compact mass around the poles, shutting out the water, but consider the equatorial region of the earth to be occupied by the waters of the ocean, we would manifestly have a very different scene. From the ocean moisture-laden winds would flow over the polar lands. The snowfall would necessarily be great. In short, we can not doubt but what all the land of the earth would be covered with glaciers. Although these last conceptions are purely hypothetical, they will serve the good purpose of showing the great influence that the geographical distribution of land and water have on the climate of a country. Of one thing, however, geologists have become more and more impressed of late years. That is, that continents and oceans have always had the same relative position as now; that is to say, the continents have followed a definite plan in their development. The very first part of North America to appear above the waters of the primal sea clearly outlined the shape of the future continent. Mr. Dana assures us that our continent developed with almost the regularity of a flower. Prof. Hitchcock also points out that the surface area of the very first period outlined the shape of the continent. "The work of later geological periods seems to have been the filling up of the bays and sounds between the great islands, elevating the consolidated mass into a continental area." So it is not at all probable that the lands of the globe were ever grouped, as we have here supposed them. 155 This last statement is liable, however, to leave us under a wrong impression; for although, as a whole, continental areas have been permanent, yet in detail they have been subject to wonderful and repeated changes. "Every square mile of their surface has been again and again under water, sometimes a few hundred feet deep--sometimes, perhaps, several thousand. Lakes and inland seas have been formed and been filled up with sediment, and been subsequently raised into hills, or even mountains. Arms of the sea have existed, crossing the continent in various directions, and thus completely isolating the divided portions for varying intervals. Seas have become changed into deserts and deserts into seas." It has been shown beyond all question that North-western Europe owes its present mild climate to the influence of the Gulf Stream. Ocean currents, then, are a most important element in determining the climate of a country. If we would take the case of our hypothetical polar continent again, and, instead of presenting a continuous coast line, imagine it penetrated by long straits and fiords, possessing numerous bays, large inland seas, and in general allowing a free communication with the ocean, we are very sure the effect would be widely different. Under these circumstances, says Mr. Geikie, the "much wider extent of sea being exposed to the blaze of the tropical sun, the temperature of the ocean in equatorial regions would rise above what it is at present. This warm water, sweeping in broad currents, would enter the polar fiords and seas, and everywhere, beating the air, would cause warm, moist winds to blow athwart the land to a much greater extent than they do at present; and these winds thus distributing warmth and moisture, 156 might render even the high latitude of North Greenland habitable by civilized man." So we see that it is necessary to look for such geographical changes as will interfere with the movements of marine currents. Now, it is easy to see that comparatively small geographical changes would not only greatly interfere with these currents, but might even cause them to entirely change their course. An elevation of the northern part of North America, no greater in amount than is supposed to have taken place at the commencement of the Glacial Age, would bring the wide area of the banks of Newfoundland far above the water, causing the American coast to stretch out in an immense curve to a point more than six hundred miles east of Halifax, and this would divert much of the Gulf Stream straight across to the coast of Spain. Such an elevation certainly took place, and if continued westward, Behring's Strait would also have been closed. It is to such northern elevations, shutting out the warm ocean currents, that a great many geologists look for a sufficient explanation of the glacial cold. Prof. Dana says: "Increase in the extent and height of high latitude lands may well stand as one cause of the Glacial Age." Then he points out how the rising of the land of Northern Canada and adjacent territory, which almost certainly took place, "all a sequel to the majestic uplift of the Tertiary, would have made a glacial period for North America, whatever the position of the ecliptic, or whatever the eccentricity of the earth's orbit, though more readily, of course, if other circumstances favored it." 157 It may occur to some that if high northern lands be all that is necessary for a period of cold, we ought to have had it in the Miocene Age, when there was a continuous land connection between the lands of high polar areas and both Europe and America, since we know that an abundant vegetation spread from there, as a center, to both these countries. But at that epoch circumstances were different. The great North Temperate lands were in a "comparatively fragmentary and insular condition." There were great inland seas in both Europe and Asia, through which powerful currents would have flowed from the Indian Ocean to Arctic regions. Somewhat similar conditions prevailed in North America. The western part was in an insular condition. A great sea extended over this part of the country, joining the Arctic probably on the north, through which heated water would pour into the polar sea. And so, instead of a Glacial Age, we find evidence of a mild and genial climate, with an abundant vegetation. We thus see that there are two theories as to the cause of the Glacial Age presented for our consideration. Both of them have received the sanction of scholars eminent for their scientific attainments. On inspection we see they are not antagonistic theories. They may both be true for that matter, and all would admit that whatever effect they would produce singly would be greatly enhanced if acting together. Indeed, there are very good reasons for supposing both must have acted in unison. There seem to be very good reasons for not believing that the eccentricity of the earth's orbit, acting alone, produced the glacial 158 cold. If that were the case, then whenever the eccentricity was great we should have a Glacial Age. Now, at some period of time during the long-extended Tertiary Age we are certain the eccentricity of the earth's orbit became very great, much more so, in fact, than that which is supposed to have produced the cold of the Quaternary Age. But we are equally certain there was no glacial epoch during this age. What other explanation can we give for its non-appearance except that geographical conditions were not favorable? But, on the other hand, there are certain features connected with the phenomena of the Glacial Age that seem very difficult of explanation, if we suppose that geographical changes alone produced them. We must remember that evidences of the former presence of glaciers are found widely scattered over the earth. We shall, therefore, have to assume an elevation not only for America and Europe, but extend it over into Asia, and take in the Lebanon Mountains, for they also show distinct traces of glaciers. And this movement of elevation must also have affected the Southern Hemisphere, the evidence being equally plain that at the same comparatively late date glaciers crushed over Southern Africa and South America. This is seen to prove too much. Again, how can we explain the fact that some time during the Glacial Age we had a submergence, the land standing several hundred feet lower than now, but still remained covered with ice, and over the submerged part there sailed icebergs and ice-rafts, freighted with their usual debris? That such was the state of things in Europe we are assured by some very good authorities. Neither do geographical causes afford an adequate explanation of those changes of temperature that surely took place during the Glacial Age. These last considerations show us how difficult it is to believe that 159 geographical causes could have produced the Glacial Age. We are assured that all through the geological ages the continents had been increasing in size and compactness, and that just at the close of the Tertiary Age they received a considerable addition of land to the north. The astronomer also informs us that at a comparatively recent epoch the eccentricity of the earth's orbit became very great. The conditions being favorable, it is not strange that a Glacial Age supervened. We have been to considerable length in thus explaining the position of the scientific world in regard to the cause of the Glacial Age. Our reason for so doing is that this age is, we think, so connected with the Paleolithic Age of man, that it seems advisable to have a clear understanding in regard to it. What we have to say is neither new nor original. It is simply an earnest endeavor to represent clearly the conclusions of some of our best scholars on this subject, and we have tried to give to each theory its due weight. Our conclusions may be wrong, but, if so, we have the consolation of erring in very good company. We have now gone over the ground and are ready to see what dates can be given. Though the numbers we use seem to be very large indeed, they are so only in comparison with our brief span of life. They are insignificant as compared with the extent of time that has surely rolled by since life appeared on the globe. Let us, therefore, not be dismayed at the figures the astronomer sets before us. About two hundred and fifty thousand years ago the earth's path around 160 the sun was much the same as that of the present. No great changes in climate were liable to take place at that time. During the next fifty thousand years the eccentricity steadily increased. Towards the end of that time all that was necessary to produce a glacial epoch in the Northern Hemisphere was favorable geographical causes, and that our earth should reach its point nearest the sun in Summer. This it must have done when about half that time had elapsed. We can in imagination see what a slow deterioration of climate took place. Thousands of years would come and go before the change would be decisive. But a time must have at length arrived when the vegetation covering the ground was such as was suited only for high northern latitudes. The animals suited for warm and temperate regions must have wandered farther south; others from the north had arrived to take their place. We can see how well this agrees with the changes of climate at the close of the Pliocene Age. The snows of the commencing Glacial Age would soon begin to fall, finally the sun would not melt them off of the high lands, and mountain peaks, and so a Glacial Age would be ushered in. We have referred to the fact that the earth reaches its perihelion point a little earlier each year, and, as a consequence, we would have periods of mild climate alternating the cold. This extended period of time, equal to twenty-one thousand of our ordinary years, has been named the Great Year of our globe. Mr. Wallace has pointed out some very good reasons for thinking Mr. Croll's theory must be modified on this point. He thinks that when once a Glacial Age was fairly fastened on a hemisphere, it would retain its grasp as long as the eccentricity remained high, but whenever the Summer of the Great Year came to that 161 hemisphere, it would melt back the glacial ice for some distance, but this area would be recovered by the ice when the Winter of the Great Year supervened. These effects would be different when the eccentricity itself became low. Then we would expect the glacial conditions to vanish entirely when the Summer of a Great Year comes on. As we have made the theoretical part of this chapter already too long, we must hurry on. We can only say that this view is founded on the fact that when a country was covered with snow and ice, it had so to speak, a great amount of cold stored up in it, so much, in fact, that it would not be removed by the sun of a new geological Summer. This ought to be acceptable to such geologists as are willing to admit the advance and retreat of the great glacier, but yet doubt the fact of the interglacial mild climate. But now to return to the question of time about two hundred and twenty thousand years ago. Then the Northern Hemisphere, according to this theory, was in the grasp of a Glacial Age. According to Mr. Wallace, as long as the eccentricity remained high, there could be no great amelioration of climate, except along the southern border of the ice sheet, which might, for causes named, vary some distance during the Great Year. Two hundred thousand years ago the eccentricity, then very high, reached a turning point. It then steadily, though gradually, diminished for fifty thousand years; at that time the eccentricity was so small, though considerably larger than at present, that it is doubtful if it was of any service in producing a change of climate. At that time, also, the Northern Hemisphere was passing through the Summer season of the Great Year. We ought, therefore, to have had a mild interglacial season. Except in high northern latitudes the ice should 162 have disappeared. This change we would expect to find more marked in Europe than in America. We need only recall how strong are the evidences on this point. Nearly all European writers admit at least one such mild interval, and though not wanting evidence of such a period in America, our geologists are much less confident of its occurrence. But from that point the eccentricity again increased. So when the long flight of years again brought secular Winter to the Northern Hemisphere, the glaciers would speedily appear, and as eccentricity was again high, they would again hold the country in their grasp. Fifty thousand years later, or one hundred thousand years ago, it passed its turning point again; eighty thousand years ago, it became so small that it probably ceased to effect the climate. Since then it has not been very large. Twenty-five thousand years ago it was less than it is now, but it is again growing smaller. According to this theory, then, the Glacial Age commenced about two hundred and twenty thousand years ago. It continued, with one interruption of mild climate, for one hundred and forty thousand years, and finally passed away eighty thousand years ago. What shall we say to these results? If true, what a wonderful antiquity is here unfolded for the human race, and what a wonderful lapse of time is included in what is known as the Paleolithic Age! How strikingly does it impress upon our minds the slow development of man! Is such an antiquity for man in itself absurd? We know no reason for such a conclusion. Our most eminent scholars nowhere set a limit to the time of man's first appearance. It is true, many of them do not think the evidence strong enough to affirm such an antiquity, but there are no 163 bounds given beyond which we may not pass. Without investigation some might reject the idea that man could have lived on the earth one hundred thousand years in a state of Savagism. If endowed with the attributes of humanity, it may seem to them that he would long before that time have achieved civilization. Such persons do not consider the lowliness of his first condition and the extreme slowness with which progress must have gone forward. On this point the geologists and the sociologists agree. Says Mr. Geikie: "The time which has elapsed from the close of the Paleolithic Age, even up to the present day, can not for a moment compare with the aeons during which the men of the old stone period occupied Europe." And on this subject Mr. Morgan says: "It is a conclusion of deep importance in ethnology that the experience of mankind in Savagery was longer in duration than all their subsequent experience, and that the period of Civilization covers but a fragment of the life of the race." The time itself, which seems to us so long, is but a brief space as compared with the ages nature has manifestly required to work out some of the results we see before us every day. We are sure, but few of our scholars think this too liberal an estimate. All endeavor to impress on our minds that the Glacial Age is an expression covering a very long period of time. As to the time that has elapsed since the close of the Glacial Age there is some dispute, and it may be that we will be forced to the conclusion that the close of the Glacial Age was but a few thousand years ago. Mr. Wallace assures us, however, that the time mentioned agrees well "with physical evidence of the time that has elapsed since the cold has passed away." 164 Difficulties are, however, urged by other writers. We can see at once that as quick as the glaciers are removed the denuding forces of nature, which are constantly at work, would begin to rearrange the debris left behind on the surface, and in the course of a few thousand years must effect great changes. Now, in some cases the amount of such change is so small that geologists are reluctant to believe a vast lapse of time has occurred since the glaciers withdrew. Mr. Geikie tells us of some moraines in Scotland that they are so fresh and beautiful "that it is difficult to believe they can date back to a period so vastly removed as the Ice Age is believed to be." In our own country this same sort of evidence is brought forward, and we are given some special calculations going to show that the disappearance of the glaciers was a comparatively recent thing. It will be seen that these conclusions are somewhat opposed to the results previously arrived at. In explanation Mr. Geikie thinks the cases spoken of in Scotland were not the moraines of the great glaciers, but of a local glacier of a far later date. He thinks that the climate, while not severe enough to produce the enormous glaciers of early times, was severe enough to produce local glaciers still in Scotland. It is possible that a similar explanation may be given for the evidence adduced in the United States. We can only state that, according to the difference in climate between the eastern and western sides of the Atlantic Ocean, when the climate was severe enough to produce local glaciers in Scotland, it would produce the same effect over a large part of eastern United States down to the latitude of New York City. And while it is true there would not be as much difference in climate on the two sides of the Atlantic in Glacial times as at present, since the Gulf Stream, on which such difference depends would then have less force, 165 still it was not entirely lacking, and the difference must have been considerable. Prof. Hitchcock has made a suggestion that whereas we know a period of several months elapses after the sun crosses the equator before Summer fairly comes on, so it is but reasonable to suppose that a proportionate length of time would go by after the eccentricity of the earth's orbit became small, before the Glacial Age would really pass away. He accordingly suggests it may have been only about forty thousand years since the glaciers disappeared. At the close of the Glacial Age Paleolithic man vanished from Europe. This, therefore, brings us to the conclusion of our researches into what is probably the most mysterious chapter of man's existence on the earth. It may not come amiss to briefly notice the main points thus far made in our investigation of the past. As to the epoch of man's first appearance, we found he could not be expected to appear until all the animals lower than he had made their appearance. This is so because the Creator of all has apparently chosen that method of procedure in the development of life on the globe. According to our present knowledge, man might have been living in the Miocene Age, and with a higher degree of probability in the Pliocene. But we can not say that the evidence adduced in favor of his existence at these early times is satisfactory to the majority of our best thinkers. All agree that he was living in Europe at the close of the Glacial Age, and we think the evidence sufficient to show that he preceded the glaciers, and that as a rude savage he lived in Europe throughout the long extended portion of time known as the Glacial Age. 166 We also found evidence of either two distinct races of men inhabiting Europe in the Paleolithic Age, or else tribes of the same race, widely different in time and in culture. The one people known as the men of the River Drift apparently invaded Europe from Asia, along with the species of temperate animals now living there. This people seem to have been widely scattered over the earth. The race has probably vanished away, though certain Australian tribes may be descendants of them. They were doubtless very low in the scale of humanity, having apparently never reached a higher state than that of Lower Savagism. The second race of men inhabiting Europe during the Paleolithic Age were the Cave-dwellers. They seem to have been allied to the Eskimos of the North. They were evidently further advanced than the Drift men, but were still savages. The Paleolithic Age in Europe seems to have terminated with the Glacial Age. But we are not to suppose it came to an end all over the earth at that time. On the contrary, some tribes of men never passed beyond that stage. When the light of civilization fell upon them they were still in the culture of the old Stone Age. We are to notice that in such cases the tribes thus discovered were very low in the scale. The probable data for the Paleolithic Age have formed the subject of this chapter. While claiming in support of them the opinions of some eminent scholars, we freely admit that it is not a settled question, but open to very grave objections, especially the date of the close of the Glacial Age, which seems to have been comparatively recent, at least in America. We think, however, that these objections will yet be harmonized with the general results. Neither is this claimed to be an exhaustive presentation of the matter. It is an outline only--the better to enable us to understand the mystery connected with the data of Paleolithic man. 167 In these few chapters we have been dealing with people, manners, arid times, of which the world fifty years ago was ignorant. Many little discoveries, at first apparently disconnected, are suddenly brought into new relation, and behold, ages ago, when the great continents were but just completed, races of men, with the stamp of humanity upon them, are seen filling the earth. With them were many great animals long since passed away. The age of animals was at an end. That of man had just begun. The child requires the schooling of adversity and trial to make a complete man of himself, and it is even so with races of men. Who can doubt that struggling up from dense ignorance, contending against adverse circumstances, compelled to wage war against fierce animals, sustaining life in the midst of the low temperature which had loaded the Northern Hemisphere with snow and ice, had much to do in developing those qualities which rendered civilization possible. As to the antiquity of man disclosed in these chapters, the only question that need concern us is whether it is true or not. Evidence tending to prove its substantial accuracy should be as acceptable as that disproving it. No great principle is here at stake. The truth of Divine Revelation is in no wise concerned. There is nothing in its truth or falsity which should in any way affect man's belief in an overruling Providence, or in an immortality beyond the grave, or which should render any less desirable a life of purity and honor. On the contrary, we think one of the greatest causes of thanksgiving mortals have is the possession of intellectual powers, which enable us to here and there catch a glimpse of the greatness of God's universe, which the astronomer 168 at times unfolds to us; or, to dimly comprehend the flight of time since "The Beginning," which the geologist finds necessary to account for the stupendous results wrought by slow-acting causes. It seems to us eminently fitting that God should place man here, granting to him a capacity for improvement, but bestowing on him no gift or accomplishment, which by exertion and experience he could acquire; for labor is, and ever has been, the price of material good. So we see how necessary it is that a very extended time be given us to account for man's present advancement. Supposing an angel of light was to come to the aid of our feeble understanding, and unroll before us the pages of the past, a past of which, with all our endeavors, we as yet know but little. Can we doubt that, from such a review, we would arise with higher ideas of man's worth? Our sense of the depths from which he has ascended is equated only by our appreciation of the future opening before him. Individually we shall soon have passed away. Our nation may disappear. But we believe our race has yet but fairly started in its line of progress; time only is wanted. We can but think that that view which limits man to an existence extending over but a few thousand years of the past, is a belittling one. Rather let us think of him as existing from a past separated from us by these many thousand years; winning his present position by the exercise of God-given powers.
