In regard to the population, as well as its geographical character, Africa naturally divides itself into two great portions, north and south of the mountains of Kong and the Jebel el Komar, which give rise to the waters of the Senegal, the Niger and the Nile. To the north of this line, Africa is ruled, and partially occupied by foreign races, who have taken possession of all the fertile districts, and driven the aboriginal population into the mountains and deserts of the interior. It is consistent with general experience, that in proportion as civilization extends itself, the aboriginal race of the natives become either extinct, or are driven farther and farther into the interior, where they in time are lost and swept from the catalogue of the human race. South of this line, we find Africa entirely peopled with the Negro race, who alone seem capable of sustaining the fiery climate, by means of a redundant physical energy scarcely compatible with the full development of the intellectual powers of man. Central Africa is a region distinguished from all others, by its productions and climate, by the simplicity and yet barbarian magnificence of its states; by the mildness and yet diabolical ferocity of its inhabitants, and peculiarly by the darker nature of its superstitions, and its magical rites, which have struck with awe strangers in all ages, and which present something inexplicable and even appalling to enlightened Europeans; the evil principle here seems to reign with less of limitation, and in recesses inaccessible to white men, still to enchant and delude the natives. The common and characteristic mark of their superstition, is the system of Fetiches, by which an individual appropriates to himself some casual object as divine, and which, with respect to himself, by this process, becomes deified, and exercises a peculiar fatality over his fortune. The barbarism of Africa, may be attributed in part its great fertility, which enables its inhabitants to live without are but chiefly to its imperviousness to strangers. Every petty state is so surrounded with natural barriers, that it is isolated from the rest, and though it may be overrun and wasted, and part of its inhabitants carried into captivity, it has never been made to form a constituent part of one large consolidated empire and thus smaller states become dependent, without being incorporated. The whole region is still more inaccessible on a grand scale, than the petty states are in miniature; and while the rest of the earth has become common, from the frequency of visitors, Africa still retains part of the mystery, which hung over the primitive and untrodden world.
