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>

We feel that we have done but scant justice to this subject, but we
assure our readers that this question has been but little studied in
this country. Referring all relics of stone to the Indians, our scholars
have been slow to recognize traces of an earlier race in America. Our
sources of information are as yet but few, and much remains to be done
in this field. In Europe as in America, scholars are still hard at work
on the Paleolithic Age, and we are to hold ourselves in readiness to
modify our opinions, or to reject them entirely and adopt new ones as
our knowledge increases.

There is one thought that occurs to us. From the combined investigations
of both European and American scholars, the Eskimo is seen to be one of
the oldest (if not the oldest) races of men now living. They afford a
striking illustration of the fact tha
