Two years later Aitken found the diamond pipe, which he had always believed lay in the mountains. Some of the stones in the cave, being unlike any ordinary African diamonds, confirmed his suspicions and set him on the track. A Kaffir tribe to the north-east of the Rooirand had known of it, but they had never worked it, but only collected the overspill. The closing down of one of the chief existing mines had created a shortage of diamonds in the world’s markets, and once again the position was the same as when Kimberley began. Accordingly he made a great fortune, and to-day the Aitken Proprietary Mine is one of the most famous in the country. But Aitken did more than mine diamonds, for he had not forgotten the lesson we had learned together in the work of resettlement. He laid down a big fund for the education and amelioration of the native races, and the first fruit of it was the establishment at Blaauwildebeestefontein itself of a great native training college. It was no factory for making missionaries and black teachers, but an institution for giving the Kaffirs the kind of training which fits them to be good citizens of the state. There you will find every kind of technical workshop, and the finest experimental farms, where the blacks are taught modern agriculture. They have proved themselves apt pupils, and to-day you will see in the glens of the Berg and in the plains Kaffir tillage which is as scientific as any in Africa. They have created a huge export trade in tobacco and fruit; the cotton promises well; and there is talk of a new fibre which will do wonders. Also along the river bottoms the india-rubber business is prospering. There are playing-fields and baths and reading-rooms and libraries just as in a school at home. In front of the great hall of the college a statue stands, the figure of a black man shading his eyes with his hands and looking far over the plains to the Rooirand. On the pedestal it is lettered “Prester John,” but the face is the face of Laputa. So the last of the kings of Africa does not lack his monument. Of this institution Mr Wardlaw is the head. He writes to me weekly, for I am one of the governors, as well as an old friend, and from a recent letter I take this passage:—
