In conclusion, a word may be said of the important part played by South African railways in the late war. A German strategist predicted that with the existing railway systems of South Africa it would be impossible to feed an army of 250,000 men in the interior of the country. Yet it was actually done, and not for a brief period only, but for nearly three years. Besides bringing the food-stuff for this host, and for the civil population besides, the railways transported guns, ammunition, horses and men up and down, back and forward as the commander-in-chief required. The magnitude of this work can be imagined when it is stated that no less than 126 trains were required for the final concentration against Delarey at Klerksdorp. The working of the railways during the war reflects the greatest credit on the managers and employées of all South African railways. It was impossible to tell when a train would run through a band of snipers, one or more of its occupants paying the penalty of death, or when the engine might be hoisted by a hidden charge of dynamite, and the machine and its drivers turned to wreckage. During the war the railway service required qualities of endurance and courage equal to those possessed by the bravest soldier in the field.

The railways, in spite of heavy rates, have made a great mining industry possible. What could they do in respect of other and ordinary industries? It is a question of rates. Given recognition of the principle that railways should be the most essential part of the governmental plant spoken of by Lord Milner--plainly to be used for developing the country, and not for the use of extracting revenue to which it is at present put, not gold-mining alone, but a hundred industries would presently flourish. On the Rand there are already great engineering works contending against many difficulties, and especially the cost of labour. These works execute repairs for the mines, make castings, and even manufacture new machinery. A great future industry, which for the present is impossible on account of want of railway facilities, is the exploitation of the rich iron ores of the Transvaal. It is stated that a syndicate with large capital has been formed to undertake this work on a large scale when the conditions are favourable, and within the next few years it is probable that the Middelburg district will have smelting furnaces, foundries, rolling mills, and all the varied works of a young iron and steel industry which may eventually take a leading place in the world. Mr. Carnegie recently stated that the iron ores of Britain will be exhausted in twenty-five years, and those of the United States in sixty years. The extensive deposits of the Transvaal should last for centuries.
