yet no theory is generally accepted. The opinions of those who have
written on the subject are hopelessly in contradiction with one
another, and good authorities are arrayed on opposite . sides. . . .
(87:246).
Recent writers, such as Daly (98:257), Umbgrove (429:285),
and Gutenberg (194:205), agree that the situation described
by Coleman is essentially unchanged. In January, 1953, Professor
J. K. Charlesworth, of Queen's University, Belfast,
expressed the opinion that
The cause of all these changes, one of the greatest riddles in geological
history, remains unsolved; despite the endeavors of generations of
astronomers, biologists, geologists, meteorologists and physicists, it
still eludes us (75:3).
A volume on climatic change, edited by Dr. Harlow
Shapley (375), while introducing minor refinements in various
theories, in no way modifies the general effect, which is
that down to the present time the theorizing about the causes
of ice ages has led nowhere.
2. The Misplaced Icecaps
One problem that writers on the ice ages have attempted to
solve, sometimes in rather fantastic ways, but without suc-
cess, is that of the wrong location of the great icecaps of the
past. These icecaps have refused to have anything to do with
the polar areas of the present day, except in a quite inci-
dental fashion.
Originally it was thought that in glacial periods the icecaps
would fan out from the poles, but then it appeared that
none of them did so, except the ones that have existed in
Antarctica. Coleman drew attention to the essential facts, as
follows:
In early times it was supposed that during the glacial period a vast
ice cap radiated from the North Pole, extending varying distances
southward over seas and continents. It was presently found, however,
that some northern countries were never covered by ice, and that in
