Note (return) — LECTURE XV

Lastly, the natives of the Isle of Pines cultivate many different kinds of yams, and they have a correspondingly large number of sacred stones destined to aid them in the cultivation by ensuring the blessing of the dead upon the work. In shape and colour these stones differ from each other, each of them bearing a resemblance, real or fanciful, to the particular species of yam which it is supposed to quicken. But the method of operating with them is much the same for all. The stone is placed before the skulls, wetted with water, and wiped with certain leaves. Yams and fish, cooked on the spot, are offered in sacrifice to the dead, the priest or magician saying, "This is your offering in order that the crop of yams may be good." So saying he presents the food to the dead and himself eats a little of it. After that the stone is taken away and buried in the yam field which it is designed to fertilise.543 Here, again, the prayer and sacrifice to the dead are purely religious rites intended to propitiate the spirits and secure their help; while the burying of the yam-shaped stone in the yam-field to make the yams grow is a simple piece of homoeopathic or imitative magic. Similarly in order to cultivate taros and bananas, stones resembling taros and bananas are buried in the taro field or the banana grove, and their magical virtue is reinforced by prayers and offerings to the dead.544
