In Corea the souls of people who die of the plague or by the roadside, and of women who expire in childbirth, invariably take up their abode in trees. To such spirits offerings of cake, wine, and pork are made on heaps of stones piled under the trees. In China it has been customary from time immemorial to plant trees on graves in order thereby to strengthen the soul of the deceased and thus to save his body from corruption; and as the evergreen cypress and pine are deemed to be fuller of vitality than other trees, they have been chosen by preference for this purpose. Hence the trees that grow on graves are sometimes identified with the souls of the departed. Among the Miao-Kia, an aboriginal race of Southern and Western China, a sacred tree stands at the entrance of every village, and the inhabitants believe that it is tenanted by the soul of their first ancestor and that it rules their destiny. Sometimes there is a sacred grove near a village, where the trees are suffered to rot and die on the spot. Their fallen branches cumber the ground, and no one may remove them unless he has first asked leave of the spirit of the tree and offered him a sacrifice. Among the Maraves of Southern Africa the burial-ground is always regarded as a holy place where neither a tree may be felled nor a beast killed, because everything there is supposed to be tenanted by the souls of the dead. In most, if not all, of these cases the spirit is viewed as incorporate in the tree; it animates the tree and must suffer and die with it. But, according to another and probably later opinion, the tree is not the body, but merely the abode of the tree-spirit, which can quit it and return to it at pleasure. The inhabitants of Siaoo, an East Indian island, believe in certain sylvan spirits who dwell in forests or in great solitary trees. At full moon the spirit comes forth from his lurking-place and roams about. He has a big head, very long arms and legs, and a ponderous body. In order to propitiate the wood-spirits people bring offerings of food, fowls, goats, and so forth to the places which they are supposed to haunt. The people of Nias think that, when a tree dies, its liberated spirit becomes a demon, which can kill a coco-nut palm by merely lighting on its branches, and can cause the death of all the children in a house by perching on one of the posts that support it. Further, they are of opinion that certain trees are at all times inhabited by roving demons who, if the trees were damaged, would be set free to go about on errands of mischief. Hence the people respect these trees, and are careful not to cut them down.
