the fruitfulness of its owner. The Caffres of Sofala, in East Africa, had a great dread of being struck with anything hollow, such as a reed or a straw, and greatly preferred being thrashed with a good thick cudgel or an iron bar, even though it hurt very much. For they thought that if a man were beaten with anything hollow, his inside would waste away till he died. In eastern seas there is a large shell which the Buginese of Celebes call the "old man" (kadjâwo). On Fridays they turn these "old men" upside down and place them on the thresholds of their houses, believing that whoever then steps over the threshold of the house will live to be old. At initiation a Brahman boy is made to tread with his right foot on a stone, while the words are repeated, "Tread on this stone; like a stone be firm"; and the same ceremony is performed, with the same words, by a Brahman bride at her marriage. In Madagascar a mode of counteracting the levity of fortune is to bury a stone at the foot of the heavy house-post. The common custom of swearing upon a stone may be based partly on a belief that the strength and stability of the stone lend confirmation to an oath. Thus the old Danish historian Saxo Grammaticus tells us that "the ancients, when they were to choose a king, were wont to stand on stones planted in the ground, and to proclaim their votes, in order to foreshadow from the steadfastness of the stones that the deed would be lasting."
But while a general magical efficacy may be supposed to reside in all stones by reason of their common properties of weight and solidity, special magical virtues are attributed to particular stones, or kinds of stone, in accordance with their individual or specific qualities of shape and colour. For example, the Indians of Peru employed certain stones for the increase of maize, others for the increase of potatoes, and others again for the increase of cattle. The stones used to make maize grow were fashioned in the likeness of cobs of maize, and the stones destined to multiply cattle had the shape of sheep.
In some parts of Melanesia a like belief prevails that certain sacred stones are endowed with miraculous powers which correspond in their nature to the shape of the stone. Thus a piece of water-worn coral on the beach often bears a surprising likeness to a bread-fruit. Hence in the Banks Islands a man who finds such a coral will lay it at the root of one of his bread-fruit trees in the expectation that it will make the tree bear well. If the result answers his expectation, he will then, for a proper remuneration, take stones of less-marked character from other men and let them lie near his, in order to imbue them with the magic virtue which resides in it. Similarly, a stone with little discs upon it is good to bring in money; and if a man found a large stone with a number of small ones under it, like a sow among her litter, he was sure that to offer money upon it would bring him pigs. In these and similar cases the Melanesians ascribe the marvellous power, not to the stone itself, but to its indwelling spirit; and sometimes, as we have just seen, a man endeavours to propitiate the spirit by laying down offerings on the stone. But the conception of spirits that must
