The Earth's Shifting Crust by Charles Hapgood - wire of information

ANCIENT CLIMATES 71
Pauly cites another impressive line of evidence in support
of his conclusions. He has compared the locations of coal deposits
of several geological periods (many of which are now
in polar regions) with the locations of icecaps for the same
periods. He lists 34 coal deposits regarded as of Jurassic-
Liassic age and 17 of Triassic-Thaetic age, and finds that, if
it is assumed that the centers of the icecaps of that time were
located at the poles, then these coal deposits would have been
located within or just outside the tropics, as would be correct
He says:
The very definite location of these coal deposits within the Tria-
Jura tropical and subtropical zones cannot be mere coincidence. The
distribution indicates the
lithosphere has shifted
(342:96).
Of the Permo-Carboniferous coal deposits, which, he
points out, are very widely distributed over the earth, he
says that "95 out of 105 listed in The Coal Resources of the
World lie within or just outside of the tropics as determined
by the assumption that the North or South Pole lay under the
center of one of the Permo-Carboniferous ice sheets" (342:
97)-
5. The Contribution of George W. Bain
Not long ago Professor George W. Bain, of Amherst, in an
article in the Yale Scientific Magazine (18), went considerably
beyond the categories of evidence that we have so far considered.
He discussed the specific chemical processes con-
trolled by sunlight and varying according to latitude, and the
remanent chemicals typical of soils developed in the different
climatic zones. He extended this sort of analysis also to
marine sediments.
Bain's approach to the problem of evidence of climatic
change has many advantages. It avoids, for one thing, the ob-
jection that has been raised against some of the plant evidence:
that plants of the past may have been adjusted to
