more fatiguing to the horses than it otherwise would have been. By
steadily persevering we made a stage of thirty-five miles, but were
obliged to encamp at night some miles short of the little height I had
been steering for.

During our ride we passed several dry watercourses at five, ten,
twenty-five, thirty, and thirty-five miles from our last encampment. The
last we halted upon with good feed for the horses, and rainwater lodged
everywhere. All these watercourses took their course to the north,
emptying and losing themselves in the plains. In the evening heavy
showers again fell, and the night set in very dark.

September 2.--After travelling seven miles we ascended Mount Distance,
and from it I could see that the hills now bore S. and S.E. and were
getting much lower, so that we were rapidly rounding their northern
extremity. To the north and north-east were seen only broken fragments of
table lands, similar to what I found near the lake to the north-west; the
lake itself, however, was nowhere visible, and I saw that I should have
another day's hard riding before I could satisfactorily determine its
direction. Upon descending I steered for a distant low haycock-like peak
in the midst of one of the table-topped fragments; from this rise I
expected the view would be decisive, and I named it Mount Hopeless.--From
Mount Distance it bore E. 25 degrees N.

Crossing many little stony ridges, and passing the channel of several
watercourses, I discovered a new and still more disheartening feature in
the country, the existence of brine springs. Hitherto we had found
brackish and occasionally salt water in some of the watercourses, but by
tracing them up among the hills, we had usually found the quality to
improve as we advanced, but now the springs were out in the open plains,
