The human inhabitants of the Soudan would not, but for their vices and misfortunes, be disproportioned in numbers to the fauna or less happy. War, slavery, and oppression have, however, afflicted them until the total population of the whole country does not exceed at the most liberal estimate three million souls. The huge area contains many differences of climate and conditions, and these have produced peculiar and diverse breeds of men. The Soudanese are of many tribes, but two main races can be clearly distinguished: the aboriginal natives, and the Arab settlers. The indigenous inhabitants of the country were negroes as black as coal. Strong, virile, and simple-minded savages, they lived as we may imagine prehistoric men--hunting, fighting, marrying, and dying, with no ideas beyond the gratification of their physical desires, and no fears save those engendered by ghosts, witchcraft, the worship of ancestors, and other forms of superstition common among peoples of low development. They displayed the virtues of barbarism. They were brave and honest. The smallness of their intelligence excused the degradation of their habits. Their ignorance secured their innocence. Yet their eulogy must be short, for though their customs, language, and appearance vary with the districts they inhabit and the subdivisions to which they belong, the history of all is a confused legend of strife and misery, their natures are uniformly cruel and thriftless, and their condition is one of equal squalor and want.
