To-day it rained in light and fitful shallows, which, as usual, were of no use, except indeed to cause a heavy dew which wet all our blankets and things, for we always camp without tent or tarpaulin whenever it does not actually rain. The solar beams of morning soon evaporated the dew. To the west-south-west the natives were hunting, and as usual burning the spinifex before them. They do not seem to care much for our company; for ever since we left the Glen of Palms, the cave-dwelling, reptile-eating Troglodytes have left us severely alone. As there was a continuous ridge for miles to the westward, I determined to visit it; for though this little tarn, that I had so opportunely found, was a most valuable discovery, yet the number of horses I had were somewhat rapidly reducing the water supply, and I could plainly perceive that, with such a strain upon it, it could not last much more than a month, if that; I must therefore endeavour to find some other watered place, where next I may remove. On the morning of the 7th October it was evident a warm day was approaching. Mr. Carmichael and I started away to a small rocky eminence, which bore a great resemblance to the rocks immediately behind this camp, and in consequence we hoped to find more water there. The rocks bore south 62 degrees west from camp; we travelled over sandhills, through scrub, triodia, and some casuarina country, until we reached the hill in twenty miles. It was composed of broken red sandstone rock, being isolated from the main ridge; other similar heaps were in the vicinity. We soon discovered that there was neither water nor any place to hold it. Having searched all about, we went away to some other ridges, with exactly the same result; and at dark we had to encamp in the scrubs, having travelled forty miles on fifty courses. The thermometer had stood at 91 degrees in the shade, where we rested the horses in the middle of the day. Natives' smokes were seen mostly round the base of some other ridges to the south-east, which I determined to visit to-morrow; as the fires were there, natives must or should be also; and as they require water to exist, we might find their hidden springs. It seemed evident that only in the hills or rocky reservoirs water could be found.
