rate, to the same distance, with the same pauses, if any. The
climate would be growing gradually colder, but with interruptions,
for the colder and warmer phases caused in North
America by the volcanic dust and carbon dioxide (produced
by volcanic eruptions) would be universal; they would affect
the whole earth's surface in the same direction at the same
time. In Siberia, warm phases would check the deterioration
of the climate temporarily, while in North America the cold
phases would act to check its improvement. The total change
of climate in Siberia during this whole period would be very
great. Siberia would, at the beginning of the movement, have
been enjoying a warm temperate climate, warmer than that
of New York at the present time.
During the whole period, changes would gradually be taking
place in the flora in eastern Siberia. Plants adapted to
wide ranges of climate, capable of surviving in the increasing
cold, would continue to grow in Siberia. It is interesting to
note in the foregoing report of the contents of the mam-
moth's stomach that every single plant or tree associated
with the time of the mammoth's death has a range extending
considerably to the south of that latitude today. Plants unable
to survive in the increasing cold would retreat toward
the south, as two or three of the plants found in the stomach
evidently did. Arctic species and varieties would tend to invade
the region as the climate grew colder. The contents of
the mammoth's stomach would simply represent the mixture
of plants growing in Siberia during the particular part of the
period in which he lived. We learn from Runcorn that Soviet
scientists have dated a mammoth from the Taimir Peninsula,
considerably to the westward in Siberia, by radiocarbon, and
have found it to be about 12,300 years old (361). This means
that mammoths survived until toward the end of the crust
movement. The mammoth of the Beresovka may have lived
as late as or later than this, when the climate of Siberia had
deteriorated a great deal, though by no means to the present
level. The possibility exists that if we could find a mammoth
that had died during the earlier phase of the displacement
