austere veld of the central tableland, the great grass wildernesses, which are as characteristic of South Africa as the prairies and the pampas of America, and, like them, became the home and hunting-ground of a race of martial horsemen. Agriculture, following nature, divides the veld into three parts, the "High," "Bush," and "Low" Velds; but it is the first and greatest of these which stamps the central tableland with its peculiar military characteristics. Almost the whole of the Orange Free State, and the Transvaal east of the Natal railway, are High Veld, which may be taken to mean any grassland lying at an elevation of about 4,000 feet, upon which all vegetation withers in the dry season, while in spring and summer it is covered with nutritious herbage. The Low Veld lies properly between longitude 31° and the tropical eastern coast; while the Bush Veld is usually understood to mean the country lying between the Pretoria-Delagoa railway and the Limpopo river. The terms, however, are very loosely used. The Low Veld differs widely from the High Veld. Upon the former is rich--almost rank--vegetation and pasture flourishing throughout the year. But the climate is hot, moist, and unhealthy; and the Boer farmers, forced by the course of the seasons to drive their flocks from the sparkling, invigorating air of the uplands to the steamy lowlands, were wont to take the task in turn amongst themselves, as an unpleasant one to be performed as seldom as possible. [Sidenote: Transvaal High Veld.] The High Veld of the Transvaal differs slightly from that of the Free State in appearance. It is more broken and undulating; the range of vision, at times apparently boundless in the southern state, is rarely extensive, except from the summit of a kopje, being usually bounded by the low ridge-lines of one of those great, gentle, almost imperceptible, rolls of the ground which are a feature of the Transvaal veld, and with its hidden watercourses, its peculiar tactical danger. A mountain range is seldom out of sight; and, speaking generally, the Transvaal may be said to be less sombre than the southern or western districts of the great plateau. [Sidenote: The kopjes.]
