The loss of crops and stock became a still more serious matter than even the destruction of farm buildings--a measure which had almost entirely been abandoned. Having regard to the inexpensive character of these structures, this measure, to quote Sir Alfred Milner, was a "comparatively small item" in the total damage caused by the war to the agricultural community. But, he said, the wanton and malicious injury done to the headgear, stamps, and other apparatus of some of the outlying mines by Boer raiders was a form of destruction for which there was no excuse. It was a vandalism unjustified by the requirements of military operations and outside the scope of civilised warfare. Directly or indirectly, all South Africa, including the agricultural population, owes its prosperity to the mines, and, of course, especially to the mines of the Transvaal. To money made in mining it is indebted for such progress, even in agriculture, as it has recently made, and the same source will have to be relied upon for the recuperation of agriculture after the ravages of war. The damage done to the mines Lord Milner estimated was not large "relatively to the vast total amount of the fixed capital sunk in them. The mining area," he said, "is excessively difficult to guard against purely predatory attacks having no military purpose, because it is, so to speak, 'all length and no breadth'--one long thin line, stretching across the country from east to west for many miles. Still, garrisoned as Johannesburg now is, it was only possible successfully to attack a few points in it. Of the raids previously made, and they have been fairly numerous, only one has resulted in any serious damage. In that instance the injury done to the single mine attacked amounted to £200,000, and it is estimated that the mine is put out of working for two years. This mine is only one out of a hundred, and is not by any means one of the most important. These facts may afford some indication of the ruin which might have been inflicted, not only on the Transvaal and all South Africa, but on many European interests, if that general destruction of mine works which was contemplated just before our occupation of Johannesburg had been carried out. However serious in some respects may have been the military consequences of our rapid advance to Johannesburg, South Africa owes more than is commonly recognised to that brilliant dash forward, by which the vast mining apparatus, the foundation of all her wealth, was saved from the ruin threatening it."
