Resumed our route at 5.50 a.m. and steered north 20 degrees east till 8.0, then 40 degrees and 60 degrees till 1.0 p.m., when we encamped at a shallow pool of water near the creek, and about three miles above camp 48, as the route only traversed the level flats near the creek. Nothing worthy of further notice was seen, the channel being split into small hollows, some of which retained a little water. The grass was much dried up and limited to the flat near the creek, the more remote portions being covered with triodia. The day was hot and nearly calm, but at noon we were benefited by a few passing clouds, and at 6.0 p.m. a dry thunderstorm cooled the air from 100 degrees to 93 degrees, but the temperature rose at 8.0 to 96 degrees. 13th March. At 5.50 steered north 10 degrees east, crossing the creek several times, and at 10.0 turned to the north-north-east and north-east, crossing the sandstone hills, round which the creek turns at a right angle, and at 12.10 p.m. camped on the creek near our track of the 29th February. Nearly all the pools of water had dried up, and the water at the camp had become brackish; some of the pools, however, must be permanent, as there were small fish in them. A great party of natives appeared to be travelling up the creek, as fresh fires are constantly seen to the north-east along its course. A cool breeze from the west to north-east moderated the heat, the temperature at 2 p.m. 103 degrees; passing clouds from the east in the afternoon. FOLLOW UP STURT'S CREEK. 14th March. Resumed our route and followed the creek upwards from 5.50 a.m. till 1.50 p.m., when we camped about three miles south-west of camp 45 at the first pool before the atriplex flat. A short distance above the camp we crossed a large sandy creek, which proved to be the cause of the change in the character of Sturt's Creek below that point. As our route was at a greater distance from the creek than in tracing it down, it gave a better opportunity of ascertaining the nature of the country beyond the influence of inundation; to the north-west a vast plain traversed by low ridges of gravel and drift sand, clothed with a scanty growth of triodia and a few hakea bushes, rose gradually from the creek, but on the south-east a more abrupt sandstone slope terminated in a similar plain of somewhat greater elevation, and showed that we were still within the bounds of the desert. Moderate breeze from the north-west changing to north-east; passing clouds; a slight shower at 11.0 p.m. 15th March.
