About ten o'clock the tide became too high for us to keep the beach, and we were compelled to halt for some hours. Our horses were nearly all exhausted, and I dreaded that when we next moved on many of them would be unable to proceed far, and that, one by one, they would all perish, overcome by sufferings which those, who have not witnessed such scenes, can have no conception of. We should then have been entirely dependent upon our own strength and exertions, nearly midway between Adelaide and King George's Sound, with a fearful country on either side of us, with a very small supply of provisions, and without water. The position we were in, frequently forced sad forebodings with respect to the future, and though I by no means contemplated with apathy the probable fate that might await us, yet I was never for a moment undecided as to the plan it would be necessary to adopt, in such a desperate extremity--at all hazards, I was determined to proceed onwards. The country we had already passed through, precluded all hope of our recrossing it without the horses to carry water for us, and without provisions to enable us to endure the dreadful fatigue of forced marches, across the desert. The country before us was, it is true, quite unknown, but it could hardly be worse than that we had traversed, and the chance was that it might be better. We were now pushing on for some sand-hills, marked down in Captain Flinders' chart at about 126 1/2 degrees of east longitude; I did not expect to procure water until we reached these, but I felt sure we should obtain it on our arrival there. After this point was passed, there appeared to be one more long push without any likelihood of procuring water, as the cliffs again became the boundary of the ocean; but beyond Cape Arid, the change in the character and appearance of the country, as described by Flinders, indicated the existence of a better and more practicable line of country than we had yet fallen in with.
