CAMPBELL'S MECHANISM 341
will overcome the inertia of the crust and its friction with
the layer below it, to continue the displacements to distances
of the order of several thousand miles. It is essential to have
a force that will not be absorbed and exhausted by the work
of moving the crust. It is clear that the mechanism of cen-
trifugal effect postulated by Campbell can meet this requirement
because the effect increases in proportion as the
uncompensated mass of the is icecap moved farther from the
axis of rotation. At the same time, as I have already men-
tioned, a cause of displacement is called for that will cease to
exert these centrifugal effects at some distance from the pole,
but long before the equator is reached. To accomplish this,
the mechanism must provide that the mass responsible for
the displacement must itself disappear en route, and, as we
have seen, it must disappear rapidly.
It seems that the melting
of the icecap, as the movement brings it into warmer
latitudes, provides not only a sufficient but perhaps the only
conceivable method of explaining the facts.
Campbell has made this clear by computing the increase
of the centrifugal effect with increasing distance from the axis
for the present Antarctic icecap, assuming it to be uncom-
pensated, and assuming its displacement, without melting,
as far as the equator. He has shown (Table III, opposite p.
341, and Figure XII, p. 343) that if the icecap should be displaced
as far as the 45th parallel of South Latitude, the
tangential component of its centrifugal effect would be mul-
tiplied about six times. After this point,
centrifugal effect operating at right angles
while the total
to the axis con-
tinues to increase until the equator is reached, the tangential
component declines, and yet it is clear that the movement,
if the uncompensated mass itself remains intact, must con-
tinue to the vicinity of the equator itself. The geological
evidence already presented shows that this did not occur, but
that the movements terminated at points about one third of
the distance from the pole to the equator.
In view of the apparently inescapable logic of the geological
evidence and of the centrifugal mechanics, we must
