At a place where it left a range of rugged little peaks, basalt re-appeared at its banks, and extended for some distance, now filling flats with its rough and cellular blocks and pebbles, and again forming small hillocks of black bare rock.

As soon, however, as the river had fairly left the basaltic formation, fine large flats of a light sandy soil succeeded on both sides; on which Pandanus spiralis grew in great abundance, and to a larger size than we had seen before.

The bed of the river became very broad, and was covered with sands, shingle, and pebbles of the rocks of its upper course.

I passed through a broad rocky gap of a range tending from east to west, and, at about two miles beyond and to the north-west of it, we encamped, in lat.

17 degrees 54 minutes 40 seconds.
In passing this gap, on a previous reconnoitring ride with Brown, I met with several natives with their wives and children, encamped at the north entrance of it.
