To earn as large a revenue as possible it naturally adjusted the rates on its lines so as to penalize the freight from the colonies and favor the Delagoa Bay road. When the colonies tried in 1895 to haul freight by ox-team from their rail-head at the frontier to Johannesburg President Kruger "closed the drifts" and almost precipitated a conflict in arms. Since the war the same situation has persisted, aggravated by the completion of the harbor works and docks at Lorenzo Marques, which favors more than ever the Delagoa route. The Portuguese seaport at present receives some 67 per cent, of the traffic from the Rand, while the Cape ports, which in 1894 had 80 per cent, of the freight, now receive only n per cent. Under Lord Milner's government the unification of the railways of the Transvaal and the Orange River colony with the Central South-African Railways amalgamated the interests of the inland colonies, but left them still opposed to those of the seaboard. The impossibility of harmonizing the situation under existing political conditions has been one of the most potent forces in creating a united government which alone could deal with the question. An equally important factor has been the standing problem of the native races, which forms the background of South-African politics. In no civilized country is this question of such urgency. South Africa, with a white population of only 1,133,000 people, contains nearly 7,000,000 native and colored inhabitants, many of them, such as the Zulus and the Basutos, fierce, warlike tribes scarcely affected by European civilization, and wanting only arms and organization to offer a grave menace to the welfare of the white population. The Zulus, numbering a million, inhabiting a country of swamp and jungle impenetrable to European troops, have not forgotten the prowess of a Cetewayo and the victory of Isandhwana. It may well be that some day they will try the fortune of one more general revolt before accepting the permanent over-lordship of their conquerors. Natal lives in apprehension of such a day. Throughout all South Africa, among both British and Dutch, there is a feeling that Great Britain knows nothing of the native question.
