Still further proof of the superabundance of population of the Shillooks is manifest from the emigration which goes forward in a south-westerly direction, where considerable numbers of them, the Dembo and Dyoor, have settled on the border-lands between the Bongo and Dinka. Of these, however, I will speak hereafter; I will only pause now to remark how, in vivid contrast to the monotonous uniformity of nature which ordinarily asserts itself throughout vast tracts of Central Africa, there are even exhibited diversities of human development, differences of dialect, and peculiarities of bodily conformation. In the Shillook territory there are probably no less than 600 residents to the square mile, whilst in Bongo-land, within 180 miles to the south-west, there would be found hardly a dozen occupants on an equal area. Again, between lat. 5° and 1° N., within a range of not more than 300 miles, are to be found examples of the largest and of the smallest races of mankind—the Bari and the Akkah, of which the former might rival the Patagonians in stature, the latter being scarcely taller than Esquimaux, and considerably below a medium height. [Sidenote: SHILLOOK VILLAGES.] It should be appended to what has been said about the villages, that the entire west bank of the Nile, as far as the confines of the district reach, assumes the appearance of one single village, of which the sections are separated by intervals varying from 300 to 1000 paces. These clusters of huts are built with surprising regularity, and are so closely crowded together that they cannot fail to suggest the comparison with a thick mass of fungus or mushrooms. Every village has its overseer, whilst the overseers of fifty or seventy, or sometimes of 100 villages, are subject to a superintendent, who has the control of what may be called a “district,” and of such districts there are well nigh a hundred, each of them distinguished by its particular name. One of the descendants of the ancient kings had been reduced to entire subjection under the Government; another at the period of my first visit was still resisting to the utmost. In the centre of each village there is a circular space where, evening after evening, the inhabitants congregate, and, either stretched upon hides or squatting down on mats of ambatch, inhale the vapour from burning heaps of cow-dung to keep off the flies, or from pipes with enormous clay bowls smoke the tobacco of the country.
