[Sidenote: Trees sometimes conceived not as the body but merely as the abode of spirits.] 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 island of the Sangi group in the East Indies, 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.[121] 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.[122] On the Tanga coast of East Africa mischievous sprites reside in great trees, especially in the fantastically shaped baobabs. Sometimes they appear in the shape of ugly black beings, but as a rule they enter unseen into people’s bodies, from which, after causing much sickness and misery, they have to be cast out by the sorcerer.[123] The Warramunga tribe of Central Australia believe that certain trees are the abode of disembodied human spirits waiting to be born again. No woman will strike one of these trees with an axe, lest the blow might disturb one of the spirits, who might come forth from the tree and enter her body.[124] In the Galla region of East Africa, where the vegetation is magnificent, there are many sacred trees, the haunts of jinn. Most of them belong to the sycamore and maple family, but they do not all exhale an equal odour of sanctity. The _watêsa_, with its edible fruit, is least revered; people climb it to get the fruit, and this disturbs the jinn, who naturally do not care to linger among its boughs. The _gute tubi_, which has no edible fruit, is more sacred. Every Galla tribe has its sacred tree, which is always one individual of a particular species called _lafto_. When a tree has been consecrated by a priest it becomes holy, and no branch of it may be broken. Such trees are loaded with long threads, woollen bands, and bracelets; the blood of animals is poured on their roots and sometimes smeared on their trunks, and pots full of butter, milk, and flesh are placed among the branches or on the ground under them. In many Galla tribes women may not tread on the shadow of
