The British possessions in Southern Africa, at the present day, consist of what has long been known as the Cape Colony, or the country extending from the extreme southern point of the continent to the 29th degree of south latitude; of a district adjoining on the east, called British Kaffraria; and a detached territory, called Natal, lying far removed from the rest, on the eastern coast, and bordering on the country called Delagoa, of which the possession is claimed by the Portuguese. In so large an extent of country there is, of course, much diversity of soil and general appearance, but it is unquestionable that the parts best adapted, on the whole, to European settlement, are the eastern districts, including Natal. The extent and population of each of these divisions may be roughly stated at--Cape Colony and British Kaffraria, 150,000 square miles, and 200,000 inhabitants; Natal, 18,000 square miles, and 20,000 inhabitants. In the Cape Colony the white and the coloured population are of about equal amount, [see Note 1], but in British Kaffraria and Natal the number of white inhabitants is as yet but small. Among the white inhabitants, those of Dutch origin greatly predominate, as is shown by a Government return of the various religious persuasions, in 1846, where, out of 70,310 white Christians, no less than 51,848 belong to the Dutch Reformed Church. Southern Africa may be described as consisting of a series of terraces rising one above the other as they recede from the sea, and then declining towards the great Orange River, which, after a long course, generally from east to west, falls into the Atlantic Ocean about 500 miles north of the Cape. On the sea-shore is a belt of land, consisting of a level plain, from 10 to 30 miles in breadth, with some gentle hills, generally fertile, and enjoying a mild climate, but backed by a chain of low mountains called the Lange Kloof, or Long Pass, which support a wide table-land, or karroo, as it is termed, consisting generally of barren plains, yet well adapted to sheep-farming. Beyond, rises another mountain-chain called the Zwaarte Bergen, or Black Mountains, and further north a still wider table-land, called the Great Karroo, which is by some travellers compared to the steppes of Tartary; rain seldom falls here; the climate is rigorous at one season and excessively hot at another, and even sheep-farming can hardly be carried on. But further north, as the land slopes towards the Orange River, the climate is more equal, and the land increases in fertility, so that large herds of cattle are reared. A somewhat similar series of terraces is found on the western coast, but their direction is north and south.
