The Asiatic plains in the south, are, however, preserved from such abrupt alternations; numerous water-courses, leaping downward from the snowy fountains of the Himalayan chain, refresh and fertilize these countries, which are almost everywhere subject to the dominion of man. Analagous causes, in the grand rich islands of the warm Indian seas, produce similar effects; there, also, the very deserts are humid regions, and tall grasses, bushes, shrubs, reeds, and climbing plants grow in a rank and luxuriant chaos which we designate by the name of jungles, in whose dense obscurity the tiger makes his lair, and the serpent conceals his deadly venom! In the immense triangle defined by that portion of the African continent which extends from the Mountains of the Moon to the Cape of Good Hope, nature has maintained almost intact her savage independence; but she displays there her most varied forms, from the snow-crested ice-bound mountain to the lowest and most monotonous plain, from the impenetrable forest to the nakedest and barrenest steppe. To enable the reader to comprehend these widely different aspects, and to describe the peculiar characteristics of each region of this immense continent, it will be necessary for us to recapitulate its most important geographical features. * * * * * A vast plateau, of comparatively slight elevation, occupies all Southern Africa, extending eastward as far as the fifth or sixth degree north of the equator. To the north-west, it is bounded by the mountains of Senegambia; to the north-east, by those of Abyssinia. On the east and west, the mountains descend to the very shore in secondary chains; to the south the table-land is brought down to the sea in a series of terraces which separate the mountain-ranges. At its southern extremity, the African continent is from 550 to 600 miles broad. It is occupied by the British colony of the Cape, which is bounded on the north by the Orange River. The most striking features of the physical geography of this part of Africa, and which determine in the main its climate and natural productions, are three chains of mountains disposed parallel to one another and to the southern coast. These are separated by terraces or upland plains, each range forming the boundary of the lower and the abutment of the higher terrace. The communication is maintained by transverse valleys, which are often of a highly romantic character. The loftiest and most inland chain is christened in different parts of its course the Roggeveld Bergen, the Nieuveld Bergen, and the Sneeu Bergen, or "Snowy Mountains." Of these the loftiest summit is the Compass Berg, 10,000 feet in altitude. The second chain, the Black Mountains, though not so lofty are more massive, and, in truth, composed of two or three chains in close juxtaposition. The third, or last chain, in proceeding from south to north, varies from eighteen to fifty-four miles, enlarging towards the west.
