The idea which presides over sacrifice is obvious. The sacrificer argues that if he can make acceptable presents to the gods, they will smile upon him and be disposed to promote his ends; whereas if he keeps the whole of his possessions for worldly purposes, they will regard him with indignation, and refuse him their assistance when he may happen to stand in need of it. There is also involved in sacrifice a sense of gratitude: the gods having given us the fruits of the earth, behooves us to make some acknowledgment of their bounty.

Such notions, once propounded, were certain to be fertile. Every motive of piety and of interest would combine to support them. The piety of the worshipers, coupled with their hopes of advantage, would be stimulated by the self-interest of the priests, who generally share in the sacrifices offered. If any piece of good fortune occurred to one who was devout and liberal in sacrificing, it would be attributed to the satisfaction felt by the gods at his exemplary conduct. If ill fortune befell those who had neglected to sacrifice, this would be an equally manifest indication of their high displeasure. As soon, therefore, as the step was taken—and it was one of the earliest in the religious history of man—of instituting sacrifices to idols or to deities, the worshipers vied with one another in the liberality of their offerings. Adopted as a mode of propitiating the celestial beings by spontaneous gifts, it became, among all nations whose religious belief had arrived at a state of flexity and consolidation, a positive duty; much as monarchs have frequently exacted large and burdensome contributions under the guise of voluntary presents.

Illustrations of this conception, that sacrifice is a sort of payment for services rendered or to be rendered, might be found abundantly in many quarters. Perhaps it is seldom more quaintly expressed than by the Amazulus, who, when going to battle, sacrifice to the Amatongo, or manes of their ancestors, in order that these, in their own language, "may have no cause of complaint, because they have made amends to them, and made them bright." On reaching the enemy, they say, "Can it be, since we have made amends to the Amadhlozi, that they will say we have wronged them by anything?" And when it comes to fighting, they are filled with valor, observing that "the Amatongo will turn their backs on us without cause" (R. S. A., vol. ii. p. 133).

The objects of sacrifice are very various, but it is noticeable that they are almost invariably things held in esteem among men, and either possessing a considerable value as commodities, or capable by their properties of ministering to their pleasure. All sacrifices of meat and corn or other edibles belong to the former class; those of flowers to the latter, for these, though of little value in the market yet give great pleasure, and are much esteemed. An exception is indeed presented by the wild hordes in Kamtschatka, who, according to Steller, offer nothing to their gods but what is valueless to themselves (Kamtschatka, p. 265). If this statement does not originate in a misunderstanding of the traveler, the fact must be due to the singularly low religiosity of those people, who seem to have little reverence for the very objects of their worship.

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).

Besides porcelain collars, tobacco, maize, and skins, the American Indians used to offer "entire animals, especially dogs, on the borders of difficult or dangerous roads or rocks, or by the side of rapids." These offerings were made to the spirits who presided in these places. The great value attached by the natives of America to the dog is well known, and it is deserving of remark that the dog was the commonest victim, and that at the war-festival, which was a sort of sacrifice, it was always dogs that were offered.
