feet, or 100 degrees per mile. Therefore, at 2 mi., water would boil;
at 18 mi., glass would melt (1850 deg.); at 28 mi., every known substance
would melt (2700 deg.). Hence the crust is not likely more than 28 miles
thick,--in many places less. Rev. O. Fisher has calculated that, if
the thickness of the earth's crust is 17.5 mi., as indicated by the
San Francisco earthquake, the earth is 5,262,170 years old. If the
crust is 21.91 mi. thick, as others say, the age would be 8,248,380
years. Lord Kelvin, the well known scientist, who computed the sun's
age at 20,000,000 years, computed the earth's age at 8,302,210
years. Subtract from these computations, the years that must have
elapsed before the earth became cool enough for animal life, and the
few millions of years left would be utterly insufficient to render
evolution possible. Note how these figures agree with the age of the
earth according to the Helmholtz contraction theory. The thinness of
the earth's crust is also proven by the geysers, the volcanoes, and
the 9000 tremors and earthquakes occurring annually in all parts of
the world.

3. The surface marks on the earth point to much shorter periods of
time since the earth was a shoreless ocean than those required by
evolutionists, who are so reckless in their guesses and
estimates. They help themselves to eternity without stint. Charles
Lyell, a geologist of Darwin's time, set the example when he said,
"The lowest estimate of time required for the formation of the
existing delta of the Mississippi is 100,000 years." According to
careful examination made by gentlemen of the Coast Survey and other
U.S. officers, the time was 4,400 years--a disinterested decision. In
the face of these three arguments, it is a bit reckless to say the
earth has existed, 1,600,000,000 years,--nearly 100 times as long as
proven possible by mathematical calculation. And still more reckless
