This Elevated
Portion Of The Globe, Built Up In Great Part Of Granitic Sandstone
Rocks, Has Never Been Submerged, Nor Does It Appear To Have Undergone
Any Changes, Either Volcanic Or By The Action Of Water.
Time, working
through countless ages with the slow but certain instrument of
atmospheric influence, has rounded the surface and
Split into fragments
the granite rocks, leaving a sandy base of disintegrated portions, while
in other cases the mountains show as hard and undecayed a surface as
though fresh from Nature's foundry. Central Africa never having been
submerged, the animals and races must be as old, and may be older, than
any upon the earth.
No geological change having occurred in ages long anterior to man, as
shown by Sir R. I. Murchison theoretically so far back as the year 1852,
when Central Africa was utterly unknown, it is natural to suppose that
the races that exist upon that surface should be unaltered from their
origin. That origin may date from a period so distant, that it preceded
the Adamite creation. Historic man believes in a Divinity; the tribes of
Central Africa know no God. Are they of our Adamite race? The equatorial
portion of Africa at the Nile sources has an average altitude above the
sea-level of about 4,000 feet; this elevated plateau forms the base of a
range of mountains, that I imagine extends, like the vertebrae of an
animal, from east to west, shedding a drainage to the north and south.
Should this hypothesis be correct, the southern watershed would fill the
Tanganika lake:
