On the fifth of January, the overseer and man returned with the horses; but so little had they benefited by their two days rest, that upon being yoked up, and put to the dray, they would not move it. We were obliged, therefore, to unload once more, and lighten the load by burying a cask of water, and giving another to the horses. After this, we succeeded in getting them along, with the remainder, to the undulating plains; and here we halted for the night, after a stage of only seven miles, but one, which, short as it was, had nearly worn out the draught horses. Here we dug a large hole, and buried twenty-two gallons of water, for my own horse, and that of the black boy, on our return; and as I determined to take a man with me, with a pack-horse, nine gallons more were buried apart from the other, for them, so that when the man got his cask of water, he might not disturb ours, or leave traces by which the natives could discover it. January 6.--Sending back the dray with the overseer, at the first dawn of day, I and the native boy proceeded to the north-west, accompanied by the man leading a pack-horse with twelve gallons of water. The day turned out hot, and the road was over a very heavy sandy country; but by eleven o'clock we had accomplished a distance of seventeen miles, and had reached the furthest point from which I turned back on the 1st December. I walked alternately with the boy, so as not to oppress the riding horses, but the man walked all the way. The weather was most intensely hot, a strong wind blowing from the north-east, throwing upon us an oppressive and scorching current of heated air, like the hot blast of a furnace. There was no misunderstanding the nature of the country from which such a wind came; often as I had been annoyed by the heat, I had never experienced any thing like it before. Had anything been wanting to confirm my previous opinion of the arid and desert character of the great mass of the interior of Australia, this wind would have been quite sufficient for that purpose. From those who differ from me in opinion (and some there are who do so whose intelligence and judgment entitle their opinion to great respect), I would ask, could such a wind be be wafted over an inland sea? or could it have passed over the supposed high, and perhaps snowcapped mountains of the interior.
