Granite we had not seen for some time, though I have no doubt that it occasionally protrudes; a small piece, found near an encampment of the natives, and evidently brought there by them, clearly proved the existence of this rock at no very great distance, probably small elevations of granite may occasionally be found among the scrubs, similar to those we had so frequently met with in the same character of country.

Another substance found at one of the native encampments, and more interesting to us, not having been before met with, was a piece of pure flint, of exactly the same character as the best gun flint.

This probably had been brought from the neighbourhood of the Great Bight, in the cliffs of which Captain Flinders imagined he saw chalk, and where I hoped that some change in the geological formation of the country would lead to an improvement in its general appearance and character.
The weather had been (with the exception of one or two hot days) unusually cold and favourable for the time of year.

Our horses had enjoyed a long rest, and though the dry state of the grass had prevented them from recovering their condition, I hoped they were stronger and in better spirits, and determined to make one more effort to get round the head of the Bight;--if unsuccessful this time, I knew it would be final, as I should no longer have the means of making any future trial, for I fully made up my mind to take all our best and strongest animals, and either succeed in the attempt or lose all.
On the 29th, I commenced making preparations, and on the following day left the camp, the sheep, and four horses in charge of Mr.Scott and the youngest of the native boys, whilst I proceeded myself, accompanied by the overseer and eldest native boy on horseback, and a man driving a dray with three horses, to cross once more through the scrub to the westward.
We took with us three bags of flour, a number of empty casks and kegs, and two pack-saddles, besides spades and buckets, and such other minor articles as were likely to be required.

It was late in the day when we arrived at the plains under the sand hills; and though we had brought our six best and strongest horses, they were greatly fagged with their day's work.
