August 3.—Crossing very heavy sandy ridges, we passed at intervals one or two dry watercourses, and the beds of some small dry lakes among the sandy ridges, in one of which was a little rain water which appeared to be rapidly drying up. Watering the horses we moved on for Termination Hill, but the nature of the country had been so unfavourable, that the pack–horse was knocked up, and I was obliged to halt four miles short of our intended destination, and where there was but poor feed for the animals. After dinner I walked to Termination Hill and ascended it. Like all the others I had recently examined, it was composed principally of quartz, ironstone and a kind of slaty rock; the low hills in front exhibiting the grey limestone, whilst patches of gum scrub were observable in many places. From the summit of Termination Hill, Lake Torrens bore W. 20 degrees S. but the view was obstructed by intervening sand ridges, the elevated land on the opposite shore of the lake still appeared to continue, and was visibly further north than the lake itself, which, as I observed, was partially shut out by the ridges. To the north were low broken hills similar to those around me, but less elevated, and immediately under these hills to the westward, were heavy red sandy ridges, such as we had crossed during the day. To the eastward and ten degrees north of east were seen Flinders range, with which Mount Deception and Termination Hills were connected, by low long spurs thrown off to the northward. In the north–east the horizon was one unbroken, low, flat, level waste, with here and there small table–topped elevations, appearing white in the distance and seemingly exhibiting precipitous faces. Wherever I turned, or whatever way I looked, the prospect was cheerless and disheartening. Our stage had been twenty–two miles.
