where gravity is
geometrically increased, and while the electric current seemingly dashes
off into space toward the phantom idea of the North Pole, yet this same
electric current drops again and continues its course southward along
the inside surface of the earth's crust.

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 boasted
achievements are in advance of the inhabitants of "darkest Africa."

The distance directly across the space from inner surface to inner
surface is about six hundred miles less than the recognized diameter of
the earth. In the identical center of this vast vacuum is the seat of
electricity--a mammoth ball of dull red fire--not startlingly brilliant,
but surrounded by a white, mild, luminous cloud, giving out uniform
warmth, and held in its place in the center of this inte
