extraordinary copiousness and beauty; once learned it becomes a lingua franca to the tribes of half the continent, and serves as an introduction to literature, or rather, it is a literature in itself. It substitutes moreover, a written code of law for the arbitrary caprice of a chieftain—a change which is, in itself, an immense advance in civilisation. Manufactures and commerce spring up, not the dumb trading or the elementary bartering of raw products which we know from Herodotus to have existed from the earliest times in Africa, nor the cowrie shells, or gunpowder, or tobacco, or rum, which still serve as a chief medium of exchange all along the coast, but manufactures involving considerable skill, and a commerce which is elaborately organised; and under their influence, and that of the more settled government which Islam brings in its train, there have arisen those great cities of Negroland whose very existence, when first they were described by European travellers, could not but be half discredited. I am far from saying that the religion is the sole cause of all this comparative prosperity. I only say it is consistent with it, and it encourages it. Climatic conditions and various other influences co-operate towards the result; but what has Pagan Africa, even where the conditions are very similar, to compare with it? As regards the individual, it is admitted on all hands that Islam gives to its new Negro converts an energy, a dignity, a self-reliance, and a self-respect which is all too rarely found in their Pagan or their Christian fellow-countrymen.” [1176]
