In the appendix to his work, Captain Sabine gives an account of
experiments to determine the acceleration of the pendulum in
different latitudes. This appears to have resulted from the joint
labor of Peary and Sabine. He says: "The accidental discovery
that a pendulum on being removed from Paris to the neighborhood
of the equator increased its time of vibration, gave the first
step to our present knowledge that the polar axis of the globe is
less than the equatorial; that the force of gravity at the
surface of the earth increases progressively from the equator
toward the poles."

According to Olaf Jansen, in the beginning this old world of ours
was created solely for the "within" world, where are located the
four great rivers -- the Euphrates, the Pison, the Gihon and the
Hiddekel. These same names of rivers, when applied to streams on
the "outside" surface of the earth, are purely traditional from
an antiquity beyond the memory of man.

On the top of a high mountain, near the fountain-head of these
four rivers, Olaf Jansen, the Norseman, claims to have discovered
the long-lost "Garden of Eden," the veritable navel of the earth,
and to have spent over two years studying and reconnoitering in
this marvelous "within" land, exuberant with stupendous plant
life and abounding in giant animals; a land where the people live
to be centuries old, after the order of Methuselah and other
Biblical characters; a region where one-quarter of the "inner"
surface is water and three-quarters land; where there are large
oceans and many rivers and lakes; where the cities are
superlative in construction and magnificence; where modes of
transportation are as far in advance of ours as we with our
