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 the several strata.

The chalk had worn away from beneath the harder rock above, leaving the latter most frightfully overhanging and threatening instant annihilation to the intruder.

Huge mis-shapen masses were lying with their rugged pinnacles above the water, in every direction at the foot of the cliffs, plainly indicated the frequency of a falling crag, and I felt quite a relief when my examination was completed, and I got away from so dangerous a post.
I have remarked that the natives at the head of the Great Bight had intimated to us, that there were two places where water might be found in this neighbourhood, not far apart, and as with all our efforts we had only succeeded in discovering one, I concluded that the other must be a little further along the coast to the westward; in this supposition I was strengthened, by observing that all the native tracks we had met with apparently took this direction.

Under this impression I determined to move slowly along the coast until we came to it, and in order that our horses might carry no unnecessary loads, to take but a few quarts of water in our kegs.
On the 18th we moved on, making a short stage of fourteen miles, through a heavy, sandy, and scrubby country.

At first I tried the beach, but finding the sand very loose and unsuitable for travelling, I was again compelled to enter the scrub behind the sea-shore ridge, travelling through a succession of low scrubby undulations, with here and there the beds of dried up lakes The traces of natives were now more recent and numerous, but found principally near the bushes bearing the red berries, and which grew behind the front ridge of the coast in the greatest abundance.
