The Kimberley diamond mines, which are among the most extensive and most elaborate underground works in the world, use American-made machinery almost exclusively, not only because it is much less costly, but because no other country can furnish apparatus that will give as good results. Almost every pound of electrical machinery in use in the country was made in America and was instituted by American workmen. Instances of successful American electrical enterprises are afforded by the Cape Town, Port Elizabeth, and Pretoria street railways, almost every rail, wire, and car of which bears the marks of American manufacture. It is a marvellous revelation to find Philadelphia-made electric cars in the streets of Cape Town, condensing engines from New York State in Port Elizabeth, and Pittsburg generators and switchboards in the capital of the Transvaal, which less than fifty years ago was under the dominion of savages. Not only did Americans install the street railways, but they also secured the desirable concessions for operating the lines for a stated period. American electricians operate the plants, and in not a few instances have financially embarrassed Americans received a new financial impetus by acting in the capacities of motormen and conductors. One street car in Cape Town was for a long time distinguished because of its many American features. The Philadelphia-made car was propelled over Pittsburg tracks by means of the power passing through Wilkesbarre wires, and the human agencies that controlled it were a Boston motorman and a San Francisco conductor. It might not be pursuing the subject too far to add that of the twelve passengers in the car on a certain journey ten were Americans, representing eight different States. One of the first railroads in South Africa--that which leads from Lorenzo Marques to the Transvaal border--was built by an American, a Mr. Murdock, while American material entered largely into the construction of the more extensive roads from the coast to the interior. American rails are more quickly and more cheaply[#] obtainable in South Africa than those of English make, but the influence which is exerted against the use of other than British rails prevents their universal adoption. Notwithstanding the efforts of the influential Englishmen to secure British manufactures wherever and whenever possible, American firms have recently secured the contracts for forty thousand tons of steel rails for the Cape Colony Railway system, and the prospects are that more orders of a similar nature will be forthcoming.
