Inner World is much like the Sanskrit.

After we had given an account of ourselves to the emissaries from
the central seat of government of the inner continent, and my
father had, in his crude way, drawn maps, at their request, of
the "outside" surface of the earth, showing the divisions of
land and water, and giving the name of each of the continents,
large islands and the oceans, we were taken overland to the city
of "Eden," in a conveyance different from anything we have in
Europe or America. This vehicle was doubtless some electrical
contrivance. It was noiseless, and ran on a single iron rail in
perfect balance. The trip was made at a very high rate of speed.
We were carried up hills and down dales, across valleys and again
along the sides of steep mountains, without any apparent attempt
having been made to level the earth as we do for railroad tracks.
The car seats were huge yet comfortable affairs, and very high
above the floor of the car. On the top of each car were high
geared fly wheels lying on their sides, which were so
automatically adjusted that, as the speed of the car increased,
the high speed of these fly wheels geometrically increased.
Jules Galdea explained to us that these revolving fan-like wheels
on top of the cars destroyed atmospheric pressure, or what is
generally understood by the term gravitation, and with this force
thus destroyed or rendered nugatory the car is as safe from
falling to one side or the other from the single rail track as if
it were in a vacuum; the fly wheels in their rapid revolutions
destroying effectually the so-called power of gravitation, or the
force of atmospheric pressure or whatever potent influence it may
be that causes all unsupported things to fall downward to the
earth's surface or to the nearest point of resistance.
