Again, in many parts of Africa the richest lands, and those most favourably situated, are either uninhabited or thinly peopled, the result of intestine wars or of the export slave-trade. Mr. Administrator Goulsbury, of Bathurst, during his adventurous march from the Gambia to the Sierra Leone River, crossed league after league of luxuriant ground and found it all desert. He says, [Footnote: Blue Book of 1882, quoted in Chap. X.] 'I think the fact has never been sufficiently recognised that Africa, and especially the west coast of the continent, is but very sparsely populated.... It is not only very limited, but is, I believe, if not stationary, actually decreasing in numbers.... I commend this fact to the consideration of those who indulge in day-dreams as to the almost unlimited increase of commerce which they fondly imagine is to be the result and reward of opening up the interior of the country.' In regions richer than the Upper Gambia the disappearance of man is ever followed by a springing of bush and forest so portentous that a few hands are helpless and hopeless. Such is the case with the great wooded belt north of the Gold Coast, where even the second-growth becomes impenetrable without the matchet, and where the swamps and muds, bred and fed by torrential rains, bar the transit of travellers. The Whydah and Gaboon countries are notable specimens of once populous regions now all but deserted. Nothing more surprising, to men who visit Africa for the first time, than the over-wealth of labour in Madeira and its penury on the Western Coast. At Bathurst they find ships loading or unloading by the work of the Golah women, whose lazy husbands live upon the hardly-earned wage. They see the mail-steamers landing ton after ton of Chinese rice shipped _via_ England. The whole country with its humid surface and its reeking, damp-hot climate is a natural rice-bed. The little grain produced by it is far better than the imported, but there are no hands to work the ground. It is the same with salt, which is cheaper when brought from England: no man has the energy to lay out a salina; and, if he did, its outlay, under 'Free Trade,' would be greater than its income.
