sandstone, resting on a softer rock of a sandy or clayey character,
beneath which the shales and rocks belonging to the coal formation show
themselves, lying in unconformable beds, and often at a very high angle.
At 9.25 the stream divided into two branches, that to the east being the
most considerable; at this spot the sandstone ceased, and we commenced
ascending the granite range, the direction of which was about
north-north-west. The soil was poor and stony, producing a little feed
for stock; but it could scarcely be made available, as the country is
completely covered with thickets of acacia of small growth. At 4 p.m.
bivouacked on a small watercourse running through a level grassy flat,
bounded on both sides by thickets of wattle.

SCRUBBY COUNTRY NORTH FROM THE IRWIN RIVER.

19th September.

At 8.15 a.m. steered a nearly north course, through a country of the same
description as yesterday; crossed several small gullies trending west, in
some of which a little water still remained; at 4.20 p.m. halted for the
night at a brackish pool in a small gully trending west.

20th September.

Started at 8.0 a.m., continuing a northerly course, over a similar
description of country as during the past two days, crossing three large
gullies coming from the eastward, but apparently near their source. At
3.45 halted on a large stream-bed, with a few brackish or rather salt
pools in its sandy channel, which was in some places nearly 100 yards
wide; from our encampment we observed a very remarkable peaked hill,
distant about twenty miles, and from its outline conjectured it to be
