I ascended the hills opposite our camp, and looked over an immense and apparently flat country, out of which small peaks and short ranges rose.

The hills on which I stood were composed of Pegmatite, with patches of white Mica in large leaflets.
During the journey we found granite changing into gneiss, diorite, and quartz rock.
On the rocky crest of the hill, I gathered the pretty red and black seeds of a leguminous climbing shrub (Abrus precatorius).

Phonolithic or basaltic pebbles made me suppose that we were near to a change of country.

Our latitude was 19 degrees 58 minutes 11 seconds.
April 12 .-- We had scarcely travelled a mile and a half, when we had to cross a large creek, which increased in size higher up.

Box-tree flats and open Vitex scrub extended along its banks, and the latter, according to Mr.Roper's account, changed into dense Bricklow scrub.
