It looks as if a sudden rent had been made, so as to form the Lake, and tilt all these rocks nearly over.

On the east side of the lower part of the Lake we have two ranges of mountains, evidently granitic: the nearer one covered with small trees and lower than the other; the other jagged and bare, or of the granitic forms.
But in all this country no fossil-yielding rock was visible except the grey sandstone referred to at the beginning of this note.

The rocks are chiefly the old crystalline forms.
One fine straight tall tree in the hollows seemed a species of fig: its fruit was just forming, but it was too high for me to ascertain its species.

The natives don't eat the fruit, but they eat the large grubs which come out of it.

The leaves were fifteen inches long by five broad: they call it Unguengo.
