ould be ascertained the bedding was
horizontal, and the lamina dipping 20 degrees to 30 degrees to the north,
but often in the opposite direction. These sandstones are at least 200
feet thick, and rest on soft shales of white-brown and green colour.

The indifferent character of the country having caused the horses to
stray in search of better food, we were delayed till 8.30 a.m., when we
steered south-east over several low ridges of sandstone, wooded with
white and paper-bark gum, with triodia in the hollows. Small dry
watercourses trended to the north-east and north. At 10.20 crossed a
creek ten yards wide, with pools of water, and at 1.5 p.m. a second of
the same size, which trended to the east, was followed till 1.50, when a
small pool of water and a little grass enabled us to camp. The country
continues to be of a bad description, and covered with scrub, though of a
more open nature than before, the soil more gravelly, melaleuca less
frequent, and eucalypti and triodia more abundant. The rock is a coarse
gray sandstone, thick bedded with horizontal strata, the lamina dipping
30 degrees to north-east generally; but varying much, the peculiar
marking on the surface of the rock resembling the rippling of water, is
frequent, forming grooves two to four inches wide and half an inch deep.

A dense fog was the unusual cause of delay in collecting our horses, as
they could not be seen more than a few yards distant. At 8.45 a.m.
steered south-east through scrubs of melaleuca, acacia, grevillia, and
eucalypti; at 11.0 the country became more open, and entering a grassy
plain extending five to eight miles to the east, where it was bounded by
a low range of hills; to the south-west a level forest of white-gum ran
parallel to our route. The soil was a brown clay-loam with pebbles of
sandstone; a few box and bauhinia trees grew on the plain; the grass had
been burnt off and sprung up again very green. At 1.20 p.m. came on a
large dry creek trending north-east; it had several channels twenty yards
wide with loose sandy beds, and was bordered by casuarina, melaleuca, and
flooded-gum trees; following down the creek, at 1.15 camped at a shallow
pool in one of the side channels. About three miles before we reached the
camp Dr. Mueller had fallen some distance behind the
