They are the chief seaports on the South African coast, which by nature is singularly deficient in good and safe anchorages.

The advantages of these two, artificially improved, and combined with the relatively open and productive region immediately behind them, have made them the starting-points of the principal railroad lines by which, through the sea, the interior is linked to the outer world.
The general direction of these roads is determined, as always, by the principal objects of traffic or other interests.

Thus the line from Cape Town, ascending by a winding course through the mountains in the rear, pushes its way north to Kimberley, where are the great diamond fields, and thence on, by way of Mafeking, to the territory of the British South African Company--now known as {p.011} Rhodesia.

This lies north of the Transvaal, and, like it, is separated from the sea by the Portuguese dominion, having, however, by treaty a right of military way through the latter by the port of Beira; of which right use is now being made.
In the northern part of its course, which at present ends at Buluwayo, this road is as yet rather political than economical in its importance, joining the British entrance at the sea to the as yet little developed regions of the distant interior.

At a point called De Aar Junction, five hundred miles from Cape Town, a principal branch is thrown off to the eastward to Bloemfontein, the capital of the Orange Free State, whence it continues on to Johannesburg, the great industrial centre of the Gold Fields, and to Pretoria, the capital of the Transvaal.
