Latitude 29 degrees 59 minutes 4 seconds; longitude 117 degrees 39 minutes. 28th August. Starting at 7.35 a.m. in a west-north-west course, at 8.45 passed several small dry salt lagoons; at 9.0 ascended a granite hill, from the summit of which it was discovered that further progress in this direction was impracticable, and that we were on a peninsula, as the lake still trended south to the horizon. We therefore turned east, and at 11.35 came on the southern extension of the eastern branch of the lake; followed it nearly east till noon, then north-east and north-north-east till 1.0 p.m.; then 17 degrees, leaving the lake and crossing extensive open downs till 2.5, when a small dry salt lake was passed, and we entered thickets of acacia, which changed to gum and cypress forest; at 3.0 came to a rich grassy hill, then thickets and grassy patches, and at 4.0 reached the summit of a lofty granite hill and had an extensive view over the country. On the north side of the hill found a native well and some good grass, where we camped. Latitude 29 degrees 45 minutes 15 seconds; longitude 117 degrees 46 minutes. GRANITE HILLS AND GRASSY COUNTRY. 29th August. At 7.35 a.m. left the bivouac and steered 30 degrees through thickets; at 8.30 crossed our track of the 24th, and at 9.15 passed a salt marsh trending north-west and south-east; at 12.25 p.m. altered the course to north till 1.0; then, 37 degrees, ascended a granite hill, on which we found a few shallow pools of rainwater; then north till 4.0 p.m., and bivouacked in a grassy patch with a small hollow containing a little muddy water. Latitude 29 degrees 30 minutes 46 seconds; longitude 117 degrees 51 minutes. 30th August. Resumed our journey at 7.35 a.m., steering north over a level country with patches of brushwood and grass; at 10.35 ascended a steep grassy ridge, and found ourselves at the north-east extremity of the immense salt lake which for five days had baffled our attempts to proceed north. The lake, which was named Lake Moore, was at this part about five miles wide, and extended to the horizon to the south-west; to the north and west there were many bare granite hills; changing the course to 328 degrees, at 12.55 p.m. camped at a grassy granite hill. Latitude 29 degrees 17 minutes 56 seconds; longitude 117 degrees 47 minutes. 31st August.
