The most valuable sacrifice that can possibly be made—that of human beings—has always been common among savage or uncivilized nations. Thus, in some of the South Sea Islands, human sacrifices were "fearfully common" (N. M. E., p. 547). They prevailed among some of the negro tribes known to the missionary Oldendorp (G. d. M., p. 329). In Mexico, where the natives had arrived at a far higher condition, human sacrifices still prevailed, though the original brutality of the rite was modified by the fact of the victims being enemies. Indeed, Montezuma, when at the height of his power, expressly refused to conquer a certain province which he might easily have added to his dominions; assigning as his first reason, that he desired to keep the Mexican youth in practice; as his second and principal one, that he might reserve a province for the supply of victims to sacrifice to the gods (H. I., b. v. ch. 20). At the great Mexican festival of the Jubilee, however, it was not an enemy, but a slave, who was offered. This slave had represented the idol during the period of a year, and had received the greatest honor during his term of office, at the end of which his head was severed from his body by the priest, who then held it as high as he could, and showed it to the Sun and to the idol (H. I., b. v. ch. 28). Next in value to the human race are cattle, and these too are frequently immolated in honor of the gods. Thus among the Kafirs, "the animals offered are exclusively cattle and goats. The largest ox in a herd is specially reserved for sacrifices on important occasions; it is called the Ox of the Spirits, and is never sold except in cases of extreme necessity" (Kafirs, p. 165). Here we find it expressly stated that it is the best ox, in other words, the most valuable portion of the sacrificer's property, which is devoted to the gods. And the principle which leads in Natal to this reservation of the best will be found predominating over sacrifice throughout the world. The Soosoos, a people inhabiting the west coast of Africa, are so careful to propitiate their deity, that they "never undertake any affair of importance until they have sacrificed to him a bullock" (N. A., vol. i. p. 230). Other domestic and edible animals, being of great importance to mankind, are held worthy of the honor of sacrifice. The same writer to whom I owe the last quotation tells us of the Western Africans, that "before they begin to sow their plantations, they sacrifice a sheep, goat, fowl, or fish to the ay-min, to beg that their crop may abound; for were this neglected, they are persuaded that nothing would grow there" (Ibid., vol. i. p. 223). Oldendorp, who was particularly familiar with the Caribbean Islands, describes the sacrifices of the negroes as consisting of "oxen, cows, sheep, goats, hens, palm-oil, brandy, yams, &c." (G. d. M., p. 329).
