There remain the north-eastern Hamites, and especially the Galla branch, as the essential extraneous factor in this obscure Bantu problem. To the stream of migration described by M. Clozel as setting east and west, corresponds another and an older stream, which ages ago took a southerly direction along the eastern seaboard to the extremity of the continent, where are now settled the Zulu-Xosa nations, almost more Hamites than Negroes. The impulse to two such divergent movements could have come only from the north-east, where we still find the same tendencies in actual operation. During his exploration of the east equatorial lands, Capt. Speke had already observed that the rulers of the Bantu nations about the Great Lakes (Karagwe, Ba-Ganda, Ba-Nyoro, etc.) all belonged to the same race, known by the name of _Ba-Hima_, that is, "Northmen," a pastoral people of fine appearance, who were evidently of Galla stock, and had come originally from Gallaland. Since then Schuver found that the Negroes of the Afilo country are governed by a Galla aristocracy[230], and we now know that several Ba-hima communities bearing different names live interspersed amongst the mixed Bantu nations of the lacustrian plateaux as far south as Lake Tanganyika and Unyamweziland[231]. Here the Wa-Tusi, Wa-Hha, and Wa-Ruanda are or were all of the same Hamitic type, and M. Lionel Decle "was very much struck by the extraordinary difference that is to be found between them and their Bantu neighbours[232]." Then this observer adds: "Pure types are not common, and are only to be found amongst the aristocracy, if I may use such an expression for Africans. The mass of the people have lost their original type through intermixture with neighbouring tribes." J. Roscoe[233] thus describes the inhabitants of Ankole. "The pastoral people are commonly called Bahima, though they prefer to be called Banyankole; they are a tall fine race though physically not very strong. Many of them are over six feet in height, their young king being six feet six inches and broad in proportion to his height.... It is not only the men who are so tall, the women also being above the usual stature of their sex among other tribes, though they do injustice to their height by a fashionable stoop which makes them appear much shorter than they really are. The features of these pastoral people are good: they have straight noses with a bridge, thin lips, finely chiselled faces, heads well set on fairly developed frames, and a good carriage; there is in fact nothing but their colour and their short woolly hair to make you think of them as negroids."
