29th February.

Leaving the camp at 5.40 a.m., traced the creek to the south-west for about three miles. It formed fine reaches of water fifty to 100 yards wide; but the channel terminated suddenly in a level flat, covered with polygonum, atriplex, and grass. In this flat we passed some large shallow pools of water; at 7.30 the creek turned to the west round the north end of a rocky sandstone hill, and was joined by a tributary gully from the north, below which point the channel was a well-defined sandy bed, with long parallel waterholes on each side, but very little water remained at this time; at 9.15 the course of the creek changed to south by west, and passed through a level flat timbered with flooded-gum trees; it was about one mile wide and well grassed, but completely dried up for want of rain. The back country was thinly wooded with white-gum, and gently rising as it receded, forming sandstone hills about 100 feet high of extremely barren appearance; at 11.45 camped at a small muddy pool which would last only for a few days. A strong breeze from the west commenced early in the day, and gradually changed to the south. Thermometer, 109 degrees in the coolest shade that could be found.

DESERT OF RED SAND.

1st March.

Our horses having strayed farther than usual in search of better grass, we were delayed till 6.20 a.m., when we steered a south by west course down the valley of the creek. Immediately below the camp the country beyond the effect of inundation changed to a nearly level plain of red sand, producing nothing but triodia and stunted bushes. The level of this desert country was only broken by low ridges of drifted sand. They were parallel and perfectly straight, with a direction nearly east and west. At 11.50 camped at a fine pool of water three to five feet deep and twenty yards wide. That we had actually entered the desert was apparent, and the increase of temperature during the past three days was easily explained; but whether this desert is part of that visited by Captain Sturt, or an isolated patch, has yet to be ascertained, and the only hope is that the creek will enable us to continue our course, as the nature of the country renders an advance quite impracticable unless by following watercourses.

2nd March.

Left our camp at 6.30 a.m., and steered south-west by west, which soon took us into the sandy desert on the left bank of the creek. Crossing one of the sand ridges, got a sight of a range of low sandstone hills to the south-east, the highest of which I named Mount Mueller, as the doctor had seen them the previous evening while collecting plants on one of the sandy ridges near the camp. At 10.15 again made the creek, which had scarcely any channel to mark its course; the wide clay flat bearing marks of former inundations was the only indication visible. At 12.35 p.m. camped at a small muddy pool, the grass very scanty and dry. Traces of natives are frequent. Large flights of pigeons feed on the plains on the seeds of grass. A flock of cockatoos was also seen.
