East of the grape region is an area peculiarly adapted for the cultivation of tobacco; and east of the tobacco district, north of the coastal belt of wheat in a region of sandy scrub, the bush country, are the ostrich farms, in the hands mainly of men of considerable capital, who supply nearly all the feathers derived from the domesticated ostrich. The plumes are sometimes worth as much as $200 a pound, the ordinary feathers bringing from $5 to $7 a pound. Natal is unique in two of its agricultural industries, being the only colony that is producing tea and important quantities of cane sugar. But gold, widely scattered over the country on the interior plateau, exceeds in value all the other exports together. The world never saw such a development of gold mining in a small area as has occurred on the Witwatersrand, where Johannesburg stands. The Witwatersrand (White River Slope) is a slight elevation, the water parting between rivers, about one and a half miles wide and 125 miles long. On twenty-five miles of the rand, at and near Johannesburg, more gold was produced in the year before the Boer war than was yielded by any other country in the world, The other rich mining regions of the Transvaal and other parts of South Africa have been completely dwarfed by the wonderful product of the rand. The surveys in Matabeleland and Mashonaland show gold-bearing areas 5,000 square miles in extent, which as yet have practically no development. The mining companies on the rand and elsewhere are now preparing for far larger operations than ever before. The Kimberley diamond mines, turning out more than $20,000,000 worth of rough stones a year, supply nearly all the diamonds of commerce. Two other diamond centres in the Orange River Colony have scarcely been touched, and diamonds are found on the Limpopo River and in other regions where no mining has been undertaken. The minerals of South Africa, including iron and coal, bid fair to be for many years the largest sources of wealth; and in wool, hides, mohair, fresh fruits, and some other products, South Africa may rival other parts of the world. There are no good natural harbors except Delagoa Bay in Portuguese East Africa, but by great expenditure the harbors of Cape Town, Port Elizabeth, East London, and Durban have been adapted for great commerce. Many persons mistakenly regard Cape Town as the chief commercial centre of South Africa. It is so only in respect of the export of gold and diamonds. As it is not centrally situated for business with the interior, more of the things that South Africa sells to and buys from the rest of the world, excepting gold and diamonds, pass through Port Elizabeth than through any other port. Here is centred the largest wholesale trade. What South Africa needs is more railroads and more white labor. Manufacturing industries on an important scale are yet to come, for as yet the white population is too sparse to develop anything but the natural products of the country.
