To leave, however, this very rough general description of Africa at this point would convey a wrong idea. We have described the verdant slope from the coast, the terrace of flatter country, the central elevation and its heart; now we may imagine a series of great ridges and furrows and other radial features diverging from the heart of Africa to its very shores, besides certain isolated ridges and peaks, some of them snow-clad, and certain isolated depressions forming lakes or swamps; first the three great furrows of the Nile, Zambesi and Congo and the three great ridges formed by their dividing water-sheds, and so on through fan-like expansions of rim or ridges and furrows until the previously described concentric formation, although still there, is considerably cut up. The great central mountain mass, buttressed by its far-stretching ridges, forms _the backbone_, from which, outward and downward, in intricate articulations, extends the complicated _bony skeleton_ of Africa. Set like sparkling jewels in its crevices and depressions, the great lakes send forth the streams which, flowing through gaps in their surrounding mountain barriers, rushing through narrow channels, oozing slowly through elevated flats or bounding in beautiful cascades over steep steps, and carrying the vitalizing fluid in every direction through the length and breadth of Africa, form _its system of circulation_. Bordering the great lakes and clustering on the slopes, forests of gigantic trees form the _flesh and muscle_ of this great creation; preserved in perpetual verdure wherever water constantly remains and in long extending lines and network fringing the ever-winding banks of the streams, and finally joining with the verdant belt of the sea-coast to form the brilliant _epidermis_ of the whole, and forming background and filling to the network of these prominent features, in broad concentric curves and in belts and patches, the more stunted thorny growth, long grass, broad savanna and sandy plain, ever changing in color and aspect. The great new and beautiful world of Africa lies open before {243} us; 250,000,000 intelligent and courageous people have become exposed to the influence, for good or evil, of the civilized races. What shall we do with it and them? Quite possible is it fairly and honestly so to explore and deal with both country and people as to develop its resources and benefit them, while adding to the world's treasury of comfort-bringing products and human brotherhood the riches and the friendship of a new continent; but it must be by peaceful and just measures and by honest trade with wholesome wares. II. As a practical way of leading you in imagination to the heart of Africa, and as indicating the circumstances and experience upon which my observations on Africa are based, I shall describe one of my many journeys.
