In the high veldt the rainfall, taken at twenty-one inches, occurs in January, February, and March. The veldt grass will support one sheep per acre. Mr. Willcocks thinks that in this region--it is enclosed by lines drawn from Vereeniging to Heidelberg, Pretoria, Belfast, Amsterdam, Vryheid, Volksrust, Standerton, and the line of the Vaal River--it would be more profitable to thoroughly develop the unirrigated crops than to go in for perennial irrigation. The higher the altitude in South Africa the less the value of perennial water, except under special conditions. Perennial irrigation should first be confined to centres such as Middelburg, Standerton, and other towns which, with this aid, would give handsome profits. The annual trek from the high to the low veldt in winter might be dispensed with if sufficient winter food crops were grown with the aid of the rainfall, and the stock herded in winter in cattle and sheep folds sheltered by groves of blue gum or pine trees. The practice of trekking from high to low veldt in winter, is due to the fact that winter frosts kill the grass in the high veldt, and the farmers, in default of other food-stuffs for flocks, are forced to travel to the regions where frost is unknown. Naturally, the trekking results in 10,000 acres of veldt having to do the work of 5000. To double the value of their holdings in the high veldt, and save the trouble of the trek, the farmers need only to plant a few belts of sheltering trees, and cultivate roots and feeding stuff for flocks and herds. The low veldt, being well supplied with water, could finally become a possession of great value. The climate being unsuited to Europeans, the place has remained undeveloped; but the land, if set apart, might be made self-supporting, indeed a source of appreciable revenue to the country, if British Indians and Kafirs were encouraged to produce rice, tropical plants, &c., which would in no way compete with the temperate and sub-tropical crops of the European farmers in the other regions. "If," says Mr. Willcocks, "Indians and Kafirs were confined to the tropical belts, and the Europeans to the temperate belts, we should not see the absurd spectacle which we see to-day of the best parts of the temperate zones being inhabited almost exclusively by Kafirs, while the Europeans with great jealousy are keeping the Indians and Kafirs out of the tropical belts." No wholesale improvements in arid or semi-arid regions can be carried forward without land and water taxes, for individuals that are exempt might neglect to improve the land with impunity, and the State would be powerless to interfere to prevent whole regions lying waste and barren.
