From what has been said regarding the condition of the atmosphere, it may readily be imagined that Africa, in those parts, after all, is not so bad as people supposed it was; for, when so much moisture falls under a vertical sun, all vegetable life must grow up almost spontaneously. It does so on the equator in the most profuse manner; but down at 5° south, where there are six months' drought, the case is somewhat different; and the people would be subject to famines if they did not take advantage of their rainy season to lay in sufficient stores for the fine: and here we touch on the misfortune of the country; for the negro is too lazy to do so effectively, owing chiefly, as we shall see presently, to want of a strong protecting government. One substantial fact has been established, owing to our having crossed over ten degrees of latitude in the centre of the continent, or from 5° south to 5° north latitude, which is this: There exists a regular gradation of fertility, surprisingly rich on the equator, but decreasing systematically from it; and the reason why this great fertile zone is confined to the equatorial regions, is the same as that which has constituted it the great focus of water or lake supply, whence issue the principal rivers of Africa. On the equator lie the rainbearing influences of the Mountains of the Moon. The equatorial line is, in fact, the centre of atmospheric motion.
