EARLIER DISPLACEMENTS OF CRUST
terior. Nobody, however, has properly examined the data
cited by Forrest as his principal line of evidence.
Recently Kolbe and Malaise have produced evidence that
may cause many to turn to the work of Forrest with new
interest. From the evidence of fresh-water diatoms indicating
a former fresh-water lake on the mid-Atlantic ridge, now
about two miles below the surface of the ocean, and from the
study of the differing sediments deposited on the two sides
of the ridge, Malaise reaches the conclusion that the mid-
Atlantic range was above sea level until the end of the Pleis-
tocene (2gia:207).
Unfortunately, limitations of space must prevent further
discussion of this question. I can only refer the reader to the
works cited and to Forrest's original sources. Forrest has
made a few mistakes in discussing matters dealing with ice
sheets, but he himself calls attention to the fact that he was
trained as a zoologist, not a geologist. However, his errors are
not such as to affect the validity of his argument. The principal
weakness of his book is that he does not present the
evidence in sufficient detail, so that it is necessary to refer to
the original sources.
It is possible that the displacement of the crust that re-
sulted in the movement of the pole from Alaska to Green-
land may itself have raised the North Atlantic bpttom enough
to bring a transatlantic land connection, in the manner suggested
in Chapter IV, and that in consequence the Greenland
ice sheet may have travelled along the land bridge into
Britain. The subsequent displacement that shifted the pole
toward Hudson Bay could have brought about the resubmergence
of parts of the land bridge, and have resulted in the
destruction of the Greenland continental glacier. The final
movement of the pole to its present location could have re-
sulted in the submergence of the remnants of the land bridge.
The advantage of our hypothesis is that it seems able to
suggest both the cause of the creation of a land connection
across the North Atlantic, and the cause of its disappearance.
The fact that we have here two successive displacements of
