itself, but capable of exerting a persistent push on the earth's
crust.
If it were possible to exhaust the centrifugal effect of the
icecap by the absorption of energy in a local deformation of
the crust, the matter might wear a different aspect. But we
are to remember that, if the yielding of the crust or its dis-
placement as a whole allows the displacement of the ice mass
farther from the axis of rotation, the centrifugal effect is
thereby multiplied. In these circumstances the centrifugal
momentum cannot be absorbed locally, but must be trans-
mitted to the entire crustal shell of the earth.

has remarked that the earth's crust can transmit
mountain-building stresses to any distance (238: 2
5. The Calculations
The following are the calculations of the centrifugal effect
of the present Antarctic icecap, and of the resulting bursting
stress on the crust, as worked out by Campbell. The phraseology
is in part that of Dr. John M. Frankland, of the Federal
Bureau of Standards, who was kind enough to review these
calculations.
a. Calculation of the Centrifugal Effect of the Rotation of
the Antarctic Icecap:
Assume isostatic adjustment o, center of gravity of the ice-
cap 345 miles from the polar axis, and volume of the ice
equal to 6,000,000 cubic miles.
W = Weight of the icecap = 2.500 X 1Ql6 short tons.
F = Centrifugal effect in pounds = ,
where
gR
v Velocity of revolving icecap, 132 feet per second,
R = Distance from the axis of rotation to the center of
gravity of the icecap = 345 miles = 1,821,600 feet,
g = Acceleration due to gravity = 32.
