Thus we are led, step by step, to the recognition of a Paleolithic Age in America, and finally to the belief that the descendants of these people were Eskimos. We at once notice the coincidence of these results with some of the conclusions of Prof. Dawkins, of England, and it is desirable to trace a little farther the points of resemblance and difference between this age in America and in Europe. In this latter country we have seen the Paleolithic Age can be divided into two stages, or epochs, during which different races inhabited the country. The first, or the epoch of the men of the River Drift, long preceded the epoch of the Cave-men. It was those latter tribes only that Mr. Dawkins connects with the Eskimos. We have not yet found evidence in this country that points to such a division of the Paleolithic Age. We have no relics of Cave-men as distinguished from the men of the River Drift. It is true, we are not lacking evidence of the use of caves by various tribes,74 but there is nothing to show that such use was very ancient, or that the people were properly Paleolithic. We can not say what future discoveries will unfold, but as yet we have only implements of the River Drift type, and these are the men Dr. Abbott considers to be the ancestors of the Eskimos. In this country, then, we have shown the existence of but one race of men in the same stage of culture as the men of the River Drift, but of the same race as the men of the Cave. These results may be cited as an argument in favor of those scholars who think that the men of the River Drift and the men of the Cave were in reality the same people.75 In Europe there was apparently a long lapse of time between the disappearance of the Paleolithic tribes and the arrival of the Neolithic people, but we have no evidence of such a period in America. The Paleolithic people remained in possession until driven away by the Neolithic ones. All evidence of Paleolithic man in Europe terminated with the Glacial Age, and there is little doubt but what they date from preglacial times. Our present knowledge does not carry us any farther back in this country than the close of Glacial times. If we consider that the Glacial Age in America coincides in time with the same age in Europe, then the last statements would imply that the Paleolithic Age here was later than in Europe; in fact, that Paleolithic man had run his course in Europe before he appeared in America, and some might even go further, and say that he migrated from Europe to America. There are, however, no good grounds for such conclusions. We believe that future discoveries will show that in America also Paleolithic man was living in Glacial and preglacial times.76
