observer, lie beneath the surface and are inappreciable, in reference
to the probable wide diffusion of Christianity at some future time, are
worth all the money and labor that have been expended to produce them.

might have easily made arrangements with the Mambari to allow me to
accompany them as far as Bihe, which is on the road to that port; but it
is so undesirable to travel in a path once trodden by slave-traders that
I preferred to find out another line of march.

Accordingly, men were sent at my suggestion to examine all the country
to the west, to see if any belt of country free from tsetse could be
