The above is a fair description of the internecine wars that have been carried on between the tribes in Africa, back "to a time whereof the memory of man runneth not to the contrary." In a preceding chapter we gave quite an extended account of four Negro empires. We call attention here to the villages of these people, and shall allow writers who have paid much attention to this subject to give their impressions. Speaking of a village of the Aviia tribe called Mandji, Du Chaillu says,-- "It was the dirtiest village I had yet seen in Africa, and the inhabitants appeared to me of a degraded class of Negroes. The shape and arrangement of the village were quite different from any thing I had seen before. The place was in the form of a quadrangle, with an open space in the middle not more than ten yards square; and the huts, arranged in a continuous row on two sides, were not more than eight feet high from the ground to the roof. The doors were only four feet high, and of about the same width, with sticks placed across on the inside, one above the other, to bar the entrance. The place for the fire was in the middle of the principal room, on each side of which was a little dark chamber; and on the floor was an _orala_, or stage, to smoke meat upon. In the middle of the yard was a hole dug in the ground for the reception of offal, from which a disgusting smell arose, the wretched inhabitants being too lazy or obtuse to guard against this by covering it with earth. "The houses were built of a framework of poles, covered with the bark of trees, and roofed with leaves. In the middle of the village stood the public shed, or palaver-house,--a kind of town-hall found in almost all West-African villages. A large fire was burning in it, on the ground; and at one end of the shed stood a huge wooden idol, painted red and white, and rudely fashioned in the shape of a woman. The shed was the largest building in the village, for it was ten feet high, and measured fifteen feet by ten. It is the habit of the lazy negroes of these interior villages--at least, the men--to spend almost the whole day lying down under the palaver-shed, feeding their morbid imaginations with tales of witchcraft, and smoking their _condoquais_." But all the villages of these poor children of the desert are not so untidy as the one described above. There is a wide difference in the sanitary laws governing these villages.
