Some of these aborigines disfigure their faces by the disk-like lip-ornament, which is also fashionable in Nyassaland, and even amongst the South American Botocudos. The type often differs greatly, and while some of the widespread Mosgu tribes are of a dirty black hue, with disagreeable expression, wide open nostrils, thick lips, high cheek-bones, coarse bushy hair, and disproportionate knock-kneed legs, other members of the same family astonished Barth "by the beauty and symmetry of their forms, and by the regularity of their features, which in some had nothing of what is called the Negro type. But I was still more astonished at their complexion, which was very different in different individuals, being in some of a glossy black, and in others of a light copper, or rather rhubarb colour, the intermediate shades being almost entirely wanting. I observed in one house a really beautiful female who, with her son, about eight or nine years of age, formed a most charming group, well worthy of the hand of an accomplished artist. The boy's form did not yield in any respect to the beautiful symmetry of the most celebrated Grecian statues. His hair, indeed, was very short and curled, but not woolly. He, as well as his mother and the whole family, were of a pale or yellowish-red complexion, like rhubarb[193]."

There is no suggestion of albinism, and the explanation of such strange contrasts must await further exploration in the whole of this borderland of Negroes and Bantus about the divide between the Chad and the Congo basins. The country has until lately been traversed only at rare intervals by pioneers, interested more in political than in anthropological matters.

The Cultured Peoples of Central Sudan.

Kanem-Bornu Records.

Of the settled and more or less cultured peoples in the Chad basin, the most important are the Kanembu[194], who introduce a fresh element of confusion in this region, being more allied in type and speech to the Hamitic Tibus than to the Negro stock, or at least taking a transitional position between the two; the Kanuri, the ruling people in Bornu, of somewhat coarse Negroid appearance[195]; and the southern Baghirmi, also decidedly Negroid, originally supposed to have come from the Upper Shari and White Nile districts[196]. Their civilisation, such as it is, has been developed exclusively under Moslem influences, but it has never penetrated much below the surface. The people are everywhere extremely rude, and for the most part unlettered, although the meagre and not altogether trustworthy Kanem-Bornu records date from the time of Sef, reputed founder of the monarchy about 800 A.D. Duku, second in descent from Sef, is doubtfully referred to about 850 A.D. Hamé, founder of a new dynasty, flourished towards the end of the eleventh century (1086-97), and Dunama, one of his successors, is said to have extended his sway over a great part of the Sahara, including the whole of Fezzan (1221-59). Under Omar (1394-98) a divorce took place between Kanem and Bornu, and henceforth the latter country has remained the chief centre of political power in the Chad basin.

A long series of civil wars was closed by Ali (1472-1504), who founded the present capital, Birni, and whose grandson, Muhammad, brought the empire of Bornu to the highest pitch of its greatness (1526-45). Under Ahmed (1793-1810) began the wars with the Fulahs, who, after bringing the empire to the verge of ruin, were at last overthrown by the aid of the Kanem people, and since 1819 Bornu has been ruled by the present Kanemíyín dynasty, which though temporarily conquered by Rabah in 1893, was restored under British administration in 1902[197].

Eastern Sudanese.

Range of the Negro in Eastern Sudan.

As some confusion prevails regarding the expression "Eastern Sudan," I may here explain that it bears a very different meaning, according as it is used in a political or an ethnical sense. Politically it is practically synonymous with Egyptian Sudan, that is the whole region from Darfur to the Red Sea which was ruled or misruled by the Khedivial Government before the revolt of the Mahdi (1883-4), and was restored to Egypt by the British occupation of Khartum in 1898. Ethnically Eastern Sudan comprises all the lands east of the Chad basin, where the Negro or Negroid populations are predominant, that is to say, Wadai, Darfur, and Kordofan in the West, the Nile Valley from the frontier of Egypt proper south to Albert Nyanza, both slopes of the Nile-Congo divide (the western tributaries of the White Nile and the Welle-Makua affluent of the Congo), lastly the Sobat Valley with some Negro enclaves east of the White Nile, and even south of the equator (Kavirondo, Semliki Valley).
