It is a historical book. The war in South Africa has been no exception to the general rule that the origin of current events is to be sought in the history of the past, and their present course to be understood by an appreciation of existing conditions, which decisively control it. This is especially true of the matter here before us; because the southern extreme of Africa, like to that of the American continent, has heretofore lain far outside of the common interest, and therefore of the accurate knowledge, of mankind at large. The Cape of Good Hope and Cape Horn, in themselves remote, tempestuous, and comparatively unproductive regions, for centuries derived importance merely from the fact that by those ways alone the European world found access to the shores of the Pacific and Indian Oceans. The application of steam to ocean navigation, and the opening of the Suez Canal, have greatly modified conditions, by diverting travel from the two Capes to the Canal and to the Straits of Magellan. It is only within a very few years that South Africa, thus diminished in consequence as a station upon a leading commercial highway, has received compensation by the discovery of great mineral wealth.
