osperma and an Euphorbiacea. Our way went over rug- 
ged hills till we approached the high land towards the 
evening ; we then crossed some rivulets, near the last of 
which was a luxuriant growth of trees and thick grass. A 
Clerodendrum was found here, but I lost the flowers. 
Sept. 3. We passed over the high mountain at Man-

The slate inclined this day more towards the west, 
and the hills were better covered with wood, and distin- 
guished by many new villages. The higher parts were 
covered with a red clay. From Mangoama Gomma a view 
opened over the upper part of the river, which is expanding 
itself over the surface of a country of less elevation. Near 
the upper Sangala is a narrow passage through the moun- 
tain, down which the river precipitates itself within a very 
contracted channel. For the first tme I observed in the

From thence we directed our way more towards the river,
