My guide in the Kalahari, and for many years a chief of Bushmen there.] Meanwhile, as we had hopelessly out-distanced our heavy transport, and could not start till its arrival, we arranged a flying trip to the Great Falls, hoping to obtain a successful film of the wonderful cataract; for with an appreciation of the fact that we should be visiting places where not even a photograph had been taken before, we had obtained a cinematograph camera and many thousand feet of film. Although the volume of water was not so great as on our previous visit, I was more impressed than ever with the solemn and desolate grandeur of the place, and above all with the fact of so much potential energy being absolutely unutilised, and the strange anomaly of a huge body of water, in a land where it is such a scarce and valuable commodity, running absolutely to waste. The views were obtained with considerable difficulty, for, as I have before described, the Falls are very difficult of access, and to obtain a frontal view of them we had to operate the machine from a tiny ledge of rock overhanging the abyss at a great height, and so small that the third leg of the tripod-stand could find no footing, but hung out over the precipice, whilst the two of us operating hung on by our eyebrows to it and to the trembling rock. I was profoundly thankful when it was all over, and we were back on firm ground again, with what we hoped would prove a very fine and unique film. This preliminary canter over, and once again in Upington, we settled down to preparations for the northward trek, for our heavy belongings had arrived in our absence, and we were anxious for the road. Both guide and waggon were ready, the latter belonging to a young Dutchman named Gert du Toit, who was familiar with the fringes of the Reserve, and who was himself most anxious to accompany us; for he, too, had heard of, and believed in, the diamond-mine. And to give him his due at once, no better sportsman or companion have I ever roughed it with either in Africa or elsewhere. Old Gert Louw, my guide, was a most remarkable old chap. Full of veldt lore, and at one time famed as a hunter, his knowledge of the Kalahari was unequalled. For many years of his young manhood he had been the chosen chief of all the Bushmen that wandered there, and knew every “pan” in the whole vast expanse.
