=III. The Gallas= inhabit the region known as Nubia, lying to the south and west of Abyssinia, and the region on the two sides of the White Nile and thence southward almost to Lake Victoria. But it must be borne in mind that these divisional names are arbitrarily bestowed upon large groups, comprising millions of people, divided into scores of tribes, each more or less distinct in size, color, and social customs. The northern group of tribes have sometimes been called Nubians. Some of these, in time, became mixed with the Hamites, and, in ancient times, were dangerous enemies of the Roman Province of Africanus, and even compelled Diocletian to withdraw his garrisons from above the cataracts of the Nile. About 550 A. D. they were converted to Christianity and welded into a great people under the leadership of Silko. With the coming of the Arabs, they were gradually subdued, partly by force, still more by amalgamation; and, by the fourteenth century, they became largely Mohammedan in religion, while remaining essentially Negro in spite of Arab and Bosnian infusions. They have oval faces, large black eyes, and prominent narrow noses; in color, they are dark mahogany or bronze. Their kinsmen to the East and South are very similar in color and feature; and both are fine, sturdy types, the women often exceedingly graceful. Their social and economic life is not unlike that of the pastoral and agricultural tribes of the Sudan. The tribes farther south are of a still lighter color, some being an earthy red, while others, the Mangbattu for example, are of a lighter tint than perhaps any other tribe of Africa. =IV. The Bantus= inhabit the vast area from about Lake Victoria, comprising Eastern Equatorial and South Central Africa. Of the Equatorial tribes, the Ugandas are generally the finest types and the most progressive. Stanley tells us that he found them to be fine craftsmen. Even more than elsewhere, Uganda is a land of musicians, who have developed a great variety of native musical instruments. The Congo region also produces a fine race, physically superior to any of their kinsmen. In the mountains of the region “one sees magnificent specimens of human beings, both male and female. They are a tall, powerful people of dark brown color, often with regular features.” The tribes to the south of the Equator are among the very finest in general physical and mental development; among them are the Zulus, the Kaffirs, and others nearly as well known to the general reader. The Zulus, e. g., are tall, shapely and muscular, and often with Grecian features, the skin varying from a light clear brown to blue black. Some of these tribes are highly developed in foresight, self-control, rational interpretation, and general intelligence. Many are fearless and brave to the point of foolhardiness, and the stories of the achievements of some of their warriors read like the tales of the Scottish chiefs so fascinating to our boyhood.
