Cannibalism however, in some of its most repulsive forms, prevails amongst the Zandehs, who barter in human fat as a universal staple of trade, and amongst the Mangbattu, who cure for future use the bodies of the slain in battle and "drive their prisoners before them, as butchers drive sheep to the shambles, and these are only reserved to fall victims on a later day to their horrible and sickly greediness[218]." In fact here we enter the true "cannibal zone," which, as I have elsewhere shown, was in former ages diffused all over Central and South Africa, or, it would be more correct to say, over the whole continent[219], but has in recent times been mainly confined to "the region stretching west and east from the Gulf of Guinea to the western head-streams of the White Nile, and from below the equator northwards in the direction of Adamawa, Dar-Banda and Dar-Fertit. Wherever explorers have penetrated into this least-known region of the continent they have found the practice fully established, not merely as a religious rite or a privilege reserved for priests, but as a recognised social institution[220]." Yet many of these cannibal peoples, especially the Mangbattus and Zandehs, are skilled agriculturists, and cultivate some of the useful industries, such as iron and copper smelting and casting, weaving, pottery and wood-carving, with great success. The form and ornamental designs of their utensils display real artistic taste, while the temper of their iron implements is often superior to that of the imported European hardware. Here again the observation has been made that the tribes most addicted to cannibalism also excel in mental qualities and physical energy. Nor are they strangers to the finer feelings of human nature, and above all the surrounding peoples the Zandeh anthropophagists are distinguished by their regard and devotion for their women and children.
