July 25.—To–DAY we broke up the camp, and commenced our labours in earnest, the men and the horses having had a rest of three weeks; the latter were in splendid condition and spirits, having eaten twenty–five bushels of oats, which had been sent up in the WATERWITCH. Every thing had been well and conveniently arranged, and the whole moved on with an order and regularity that was very gratifying.

I was very ill at starting, and remained so for some days after, but as I had already been twice over the ground, and as my native boy was able to act as guide to the party, my indisposition was not of so much consequence as it would have been under other circumstances. At times I was quite incapable of any exertion, and could not attend to any thing, being hardly able to sit upon my horse for half an hour together. From the 25th to the evening of the 30th, we were engaged in travelling from Mount Arden to Depot Pool, by the same line of route by which myself and the native boy had returned from our exploration. In our progress we noticed many traces of natives around us, and saw many native fires among the hills; the people themselves did not, however, appear.

By a little trouble in examining the watercourses before encamping, we were generally able to procure water for our horses, at some distance among the hills; and we were usually fortunate enough to obtain tolerable food for them also. The grass, it is true, was generally scanty, or dry; but we found a succulent plant of the geranium tribe, bearing a small blue flower, and growing where the channels of the watercourses spread out in the plains, in the greatest abundance, and in the wildest luxuriance; of this the horses were extremely fond, and it appeared to keep them in good condition and spirits.
