“If the t’samma east is not a very big patch,” said Du Toit, “we shall find that what they have not eaten they have trampled to bits!”

The oxen had been brought in and had slept in their yokes all night, to prevent their straying, and we lost no time in getting underway. Unfortunately, Gert’s prognostications had been correct, for we found the whole width of the t’samma zone trampled for miles, and most of the few remaining t’samma smashed and spoiled. However, the oxen were able to get a feed that would keep them for a day or so, and as we expected to find more, we pushed on.

During the three days that followed we had a most anxious and wearying time, reaching several pans where excellent Kimberlite was obtained within a foot or so of the surface, but being constantly worried and baffled by the absence of water to wash it, or t’samma for ourselves and the oxen.

We were now in the heart of the desert, three long days’ trek from our waggon and t’samma patch, and simply living from hand to mouth on the few t’samma we found here and there; and, realising that we were risking rather too much, we made up our minds to return before the oxen had begun to suffer from thirst.

There was a small portion of the big t’samma patch that the gemsbok had spoiled which had escaped with slighter damage, and as the little melon grows rapidly, we hoped to find refreshment at this spot; but our bad luck held, for a troop of big baboons cleared out of it as we drew near, and we found that the destructive brutes had torn up and smashed most of those they had not eaten, and so both man and beast had to be content with very short commons.

By the time we reached the vicinity of Aar Pan we were suffering rather badly; each stray melon we found had to go to the oxen, and it appeared doubtful whether we should be able to get them out with the cart. Most of the heavier samples were thrown away to lighten the load, but even so they could scarcely be got to drag the cart, and when we got to the huge dunes at Aar Pan we could get them no farther.

We had seen thunder-showers falling in this direction, and had hoped that there might be water in the pits again, so Du Toit and myself took a billy-can and some cord and hastened across the dunes, leaving John to watch the exhausted cattle.

I said to Du Toit, “In any case there is bound to be a little in the deep pit, enough for us! Animals can’t reach it there.”

“But the puff-adder! Did van Reenen kill it outright?”

“The bullet cut it nearly in half. It would be sure to get into its hole in the rock to die!”
