"At the end of the first day's march of fifteen miles we found water at the spot to which our native guide led us. The second day the pool was found to be dry. We got there early, having started before daybreak, for the heat was tremendous. On finding the pool empty I rode ten miles down the course of the stream, and Macgregor as far up it, but found no water, and on getting back to the camp the oxen were inspanned, and we made another march; here we found water, and halted next day. "So we went on, until we were half-way across the desert. Several of the marches had been double ones, the track was heavy from the deep sand, some of the oxen had died, and all were much reduced in strength. Although Macgregor was not a man to allow that he had been wrong, I saw that he was anxious, and before advancing he sent on a horseman and the native guide two days' journey to see how the water held out. On their return they reported that twenty miles in front there was a pool of good water, and that thirty miles farther there was a small supply, which was, however, rapidly drying up. Macgregor determined to push on. The first day's march was got through, although five or six more oxen dropped by the way. The second was a terrible march; I have never known a hotter day in South Africa, and one felt blinded and crushed by the heat. The weakened teams could scarcely draw the waggons along, and by nightfall but half the journey had been performed. The oxen were turned loose and allowed for an hour or two to crop the bush; then they were inspanned again. All night long we continued our march; when, just at sunrise, we got to the place where water had been found, the pool was empty--the two days' sun since the horseman had been there had completely dried it up. We set to work to dig a hole; but the sand was shallow, the rock lying but a foot or two below, and we only got a few buckets of water, but just enough to give a swallow to each of the oxen and horses. Again we searched far up and down the course of the stream, but without success; we dug innumerable holes in its bed, but without finding water.
