at Nevada. At one time this area was
the bottom of a lake, and we can plainly see the tracks of
various animals that came down to drink. A huge mammoth visited
the place; so also did horses and other animals. Among these is
one series of tracks evidently made by a biped. Some think they
are the sandaled foot of a human being. This question is still
under discussion.

demonstrate the long-continued occupation of them by a savage

(34) Prof. Winchell, in his last work, "World Life," p. 363,
_et seq.,_ goes over the entire subject. As might be
expected, no decisive results are obtained. He sums up the
arguments to show that in this country the close of the Glacial
Age is not more than seven thousand years ago (p. 375).
The student who reads these pages and then Mr. Geikie's work,
"Prehistoric Europe," will be sorely puzzled to know what
conclusions to adopt. We can not do better than refer to the
chapter on Antiquity Paleolithic Age.
