steep and very stony.

Having hobbled the horses, I took my gun, and walked down the
watercourse, to a place where it forms a junction with a larger one, but
in neither could I find any more water. Upon my return, I found that the
native boy had caught an opossum in one of the trees near, which proved a
valuable addition to our scanty and unvaried fare. The latitude to-day
was 30 degrees 51 minutes S.

July 16.--Tracing down the watercourse we were encamped on, to the
junction before mentioned, I steered a little more to the north, to
ascend a high stony range, from which I hoped to obtain a view to the
eastward; but after considerable toil in climbing, and dragging our
horses over loose rolling stones, which put them constantly in danger of
falling back, I was not rewarded for the trouble I had taken: the view to
the east was quite shut out by high rugged ranges of ironstone and
quartz, whilst to the north, the hills appeared lower and more open.

It now became a matter of serious consideration, whether I should pursue
my researches any farther at present. I was already about 120 miles away
from my party, with barely provisions enough to last me back; and the
country, in advance, appeared to be getting daily more difficult; added

After reflecting on my position, I decided to rejoin my party without

watercourse we had crossed in the morning; intending to trace it up, for
the purpose of examining its branches. The bed of this watercourse, at
first, was very wide, and lined with gum-trees; but as I advanced, I
