Sechele, by my advice, sent men to Sekomi, asking leave for me to pass along his path, accompanying the request with the present of an ox. Sekomi's mother, who possesses great influence over him, refused permission, because she had not been propitiated. This produced a fresh message; and the most honorable man in the Bakwain tribe, next to Sechele, was sent with an ox for both Sekomi and his mother. This, too, was met by refusal. It was said, "The Matebele, the mortal enemies of the Bechuanas, are in the direction of the lake, and, should they kill the white man, we shall incur great blame from all his nation." The exact position of the Lake Ngami had, for half a century at least, been correctly pointed out by the natives, who had visited it when rains were more copious in the Desert than in more recent times, and many attempts had been made to reach it by passing through the Desert in the direction indicated; but it was found impossible, even for Griquas, who, having some Bushman blood in them, may be supposed more capable of enduring thirst than Europeans. It was clear, then, that our only chance of success was by going round, instead of through, the Desert. The best time for the attempt would have been about the end of the rainy season, in March or April, for then we should have been likely to meet with pools of rain-water, which always dry up during the rainless winter. I communicated my intention to an African traveler, Colonel Steele, then aid-de-camp to the Marquis of Tweedale at Madras, and he made it known to two other gentlemen, whose friendship we had gained during their African travel, namely, Major Vardon and Mr. Oswell. All of these gentlemen were so enamored with African hunting and African discovery that the two former must have envied the latter his good fortune in being able to leave India to undertake afresh the pleasures and pains of desert life. I believe Mr. Oswell came from his high position at a very considerable pecuniary sacrifice, and with no other end in view but to extend the boundaries of geographical knowledge. Before I knew of his coming, I had arranged that the payment for the guides furnished by Sechele should be the loan of my wagon, to bring back whatever ivory he might obtain from the chief at the lake. When, at last, Mr. Oswell came, bringing Mr. Murray with him, he undertook to defray the entire expenses of the guides, and fully executed his generous intention. Sechele himself would have come with us, but, fearing that the much-talked-of assault of the Boers might take place during our absence, and blame be attached to me for taking him away, I dissuaded him against it by saying that he knew Mr. Oswell "would be as determined as himself to get through the Desert." Before narrating the incidents of this journey, I may give some account of the great Kalahari Desert, in order that the reader may understand in some degree the nature of the difficulties we had to encounter.
