From the 12th to the 18th we remained at the sand-drifts, during which time we were engaged in attending to the horses, in sending back to recover the stores that had been left by the overseer, and in examining the country around. The natives had told me that there were two watering places at the termination of the cliffs to the eastward, and that these were situated in a somewhat similar manner to those at the head of the Great Bight. We were encamped at one, and I made several ineffectual attempts to find the other during the time the horses were recruiting. The traces of natives near us were numerous, and once we saw their fires, but they did not shew themselves at all. The line of cliffs which had so suddenly turned away from the sea, receded inland from eight to ten miles, but still running parallel with the coast; between it and the sea the country was low and scrubby, with many beds of dried up salt lakes; but neither timber nor grass, except the little patch we were encamped at. Above the cliffs the appearance of the country was the same as we had previously found upon their summits, with, perhaps, rather more scrub; pigeons were numerous at the sand-hills, and several flocks of red-crested and red-winged cockatoos were hovering about, watching for an opportunity to feast upon the red berries I have before spoken of, and which were here found in very great abundance, and of an excellent quality. The sand, as usual at our encampments, was a most dreadful annoyance, and from which we had rarely any respite. The large flies were also very numerous, troublesome and irritating tormentors. They literally assailed us by hundreds at a time, biting through our clothes, and causing us constant employment in endeavouring to keep them off. I have counted twenty-three of these blood-suckers at one time upon a patch of my trousers eight inches square.
Being now at a part of the cliffs where they receded from the sea, and where they had a last become accessible, I devoted some time to an examination of their geological character. The part that I selected was high, steep, and bluff towards the sea, which washed its base; presenting the appearance described by Captain Flinders, as noted before. By crawling and scrambling among the crags, I managed, at some risk, to get at these singular cliffs. The brown or upper portion consisted of an exceedingly hard, coarse grey limestone, among which some few shells were embedded, but which, from the hard nature of the rock, I could not break out; the lower or white part consisted of a gritty chalk, full of broken shells and marine productions, and having a somewhat saline taste: parts of it exactly resembled the formation that I had found up to the north, among the fragments of table-land; the chalk was soft and friable at the surface, and easily cut out with a tomahawk, it was traversed horizontally by strata of flint, ranging in depth from six to eighteen inches, and having varying thicknesses of chalk between
