The history of his intercourse with this people affords a striking example of the incalculable benefits which one civilized man, who possessed courage to make the experiment, might confer upon a wild nation, whose Menû or Manco Capæ he would thus become. For genius the Kaffers are decidedly superior to the Hottentots; and if the picture which Le Vaillant draws of them be correct, it would require no very extraordinary impulse to launch them into the career of civilization. He saw them, however, but for a moment, as it were; for not long after their arrival, it was discovered that several half-castes, or bastards, as they are termed at the Cape, had been commissioned by the colonists to insinuate themselves into his camp, for the purpose of discovering whether or not he was entering into an alliance with the Kaffers. This, at least, was the interpretation which, after all the information he could obtain, he was induced to put upon the matter; but, like Rousseau, he seems to have amused himself with the idea that spies were continually placed upon his movements, and by this hypothesis he explained many little events resulting much less from design than from a fortuitous concourse of circumstances. Still, the poor Kaffers, who had suffered grievously by the Dutch, fully participated in his alarm, and made a precipitate retreat into their own country, but not before they had given him a pressing invitation to follow them. Upon considering the state of the camp, and the inclinations of his people, it was judged imprudent to attempt against their will to lead them away farther from the colony; and therefore, selecting from among them a small number of the bravest, and leaving the remainder under the care of Swanspoel, he departed on his long-desired journey into Kaffer-land. Upon quitting the encampment they ascended the banks of the Great Fish River, and having forded its stream, entered Kaffer-land, moving in a north-easterly direction. The whole plain was covered with mimosa-trees, which, as Burckhardt observes, cast but a scanty shade. They were, therefore, greatly exposed to the heat of the sun, which was now intense. After marching for several days in this manner through a country which had once been inhabited, but was deserted now, and abandoned to the wild beasts, fires at night, deserted kraal, gardens overrun with weeds, and fields, the culture of which had recently been interrupted, inspired the belief that some half-stationary, half-wandering hordes must be in the neighbourhood.
