yards. The principal creek now turned to the
north, and our course was along the foot of a sandstone range 200 feet
high, till 12.40 p.m., when, altering the course to south-east, we
ascended the range and crossed the level sandy tableland covered with
scrub; descending to the south, found a small dry watercourse in an open
valley, and followed it in search of water to the north-west till 4.0
p.m., when we found a small pool of rainwater, at which we camped.

The horses had strayed so far in search of green grass that we did not
start till 10.30 a.m., when we steered south-east, crossing a spur of the
tableland which lay to the south-west; then crossing several valleys and
small watercourses trending to the north-east, camped at a shallow
waterhole at 3.20 p.m. The country was of sandstone formation and the
soil very poor, melaleuca scrubs prevailing on the lower ground, and
eucalypti, acacia, and grevillia on the hills; to the south-west the
hills were rocky, with a rounded outline, but to the north-east they were
flat-topped and of less height. The sandstones are often at a
considerable angle, but in no general direction, a thin bed of
ferruginous conglomerate rests on hard gray sandstone, imperfectly
stratified, beneath which shales of various colours exist; on the exposed
surface of the shales observed an efflorescence of sulphate of magnesia.

Resuming our route at 7.20 a.m., steered south-east and ascended a
sandstone range with horizontal strata and very abrupt on the south-east
side. Entering a wide valley, crossed two small watercourses, the second
of which was running apparently from springs, as several clumps of the
melaleuca grew on the slope of the sandstone hills from which they came.
Crossing a second spur of the tableland, descended to a small creek with
waterholes and narrow grassy flats, the general character of the country
being very poor and scrubby.

At 7.40 a.m. left the camp, and steered south-east through a succession
of miserable scrubs of eucalypti, grevillia, acacia, and jacksonia, with
patches of melaleuca. At 1.30 p.m. crossed a ridge of steep sandstone
rocks, and gradually d
