Nothing could more wildly misrepresent the reality than the idea of one's school days that the heart of Africa is a desert. Africa rises from its three environing oceans in three great tiers, and the general physical geography of these has been already sketched--first, a coast-line, low and deadly; farther in, a plateau the height of the Scottish Grampians; farther in still, a higher plateau, covering the country for thousands of miles with mountain and valley. Now fill in this sketch, and you have Africa before you. Cover the coast belt with rank yellow grass, dot here and there a palm; scatter through it a few demoralized villages; and stock it with the leopard, the hyena, the crocodile, and the hippopotamus. Clothe the mountainous plateaux next--both of them--with endless forest,--not grand umbrageous forest like the forests of South America, nor matted jungle like the forests of India, but with thin, rather weak forest,--with forest of low trees, whose half-grown trunks and scanty leaves offer no shade from the tropical sun. Nor is there anything in these trees to the casual eye to remind you that you are in the tropics. Here and there one comes upon a borassus or fan-palm, a candelabra-like euphorbia, a mimosa aflame with color, or a sepulchral baobab. A close inspection also will discover curious creepers and climbers; and among the branches strange orchids hide their eccentric flowers. But the outward type of tree is the same as we have at home--trees resembling the ash, the beech, and the elm, only seldom so large, except by the streams, and never so beautiful.[1] Day after day you may wander through these forests with nothing except the climate to remind you where you are. The beasts, to be sure, are different, but unless you watch for them you will seldom see any; the birds are different, but you rarely hear them; and as for the rocks, they are our own familiar gneisses and granites, with honest basalt-dykes boring through them, and leopard-skin lichens staining their weathered sides. Thousands and thousands of miles, then, of vast thin forest, shadeless, trackless, voiceless--forest in mountain and forest in plain--this is East Central Africa. [1] The more important of these trees are--_Napaca Kirkii_, _Brachystegia longifolia_, _Vitex umbrosa_, _Erythrina speciosa_, _Ficus sycamorus_, _Khaya senegalensis_, _Nuxia congesta_, _Parinarium mobola_, and _Erythrophlœum guineensis_.
