The scriptural curse of the "false prophet" has never been more strikingly fulfilled, than in the instance of the Kaffir nation in the year 1656. A false prophet, named Umhlahaza, professed to have received a revelation from heaven through the visions of a girl, commanding the Kaffirs to kill the whole of their cattle, and promising that, in the event of their obedience, all their forefathers, together with their cattle, should rise to life again, that they should regain their ascendancy in the land, and live in plenty and prosperity for evermore. The object of this audacious imposture was to reduce the whole nation on a sudden to such a state of suffering that, in their desperation, they would burst in upon the settlements of the white men, and everywhere exterminate them. It is strange that in a country where the flocks and herds constitute the sole wealth of the people, such an attempt should have succeeded. But it did so to a considerable extent, at all events. Those who had contrived it, however, had made one fatal omission. They ought to have concentrated the whole people on the English border, and they forgot that men enfeebled by famine would be unfitted for warfare, or indeed for any lengthened travel. An attempt was made to remedy the blunder by postponing the day of the resurrection of the chiefs and cattle, but it failed. The people had discovered the imposture, though not until they were reduced to the most frightful condition of starvation. The English colonists did all that lay in their power to relieve them, but they were wholly unable to remedy the mischief. Vast numbers died everywhere by the most terrible of all deaths, and the strength of the nation was so completely broken by the disaster, that they were rendered wholly incapable of continuing the warfare, for which in former days they had been so renowned.
