mountaineers on the north-west coast of New Guinea think that the spirits of their ancestors live on the branches of trees, on which accordingly they hang rags of red or white cotton, always in the number of seven or a multiple of seven; also, they place food on the trees or hang it in baskets from the boughs.[112] Among the Buryats of Siberia the bones of a deceased shaman are deposited in a hole hewn in the trunk of a great fir, which is then carefully closed up. Thenceforth the tree goes by the name of the shaman’s fir, and is looked upon as his abode. Whoever cuts down such a tree will perish with all his household. Every tribe has its sacred grove of firs in which the bones of the dead shamans are buried. In treeless regions these firs often form isolated clumps on the hills, and are visible from afar.[113] The Lkungen Indians of British Columbia fancy that trees are transformed men, and that the creaking of the branches in the wind is their voice.[114] In Croatia, they say that witches used to be buried under old trees in the forest, and that their souls passed into the trees and left the villagers in peace.[115] A tree that grows on a grave is regarded by the South Slavonian peasant as a sort of fetish. Whoever breaks a twig from it hurts the soul of the dead, but gains thereby a magic wand, since the soul embodied in the twig will be at his service.[116] This reminds us of the story of Polydorus in Virgil,[117] and of the bleeding pomegranate that grew on the grave of the fratricides Eteocles and Polynices at Thebes[118]. Similar stories are told far away from the classic lands of Italy and Greece. In an Annamite tale an old fisherman makes an incision in the trunk of a tree which has drifted ashore; but blood flows from the cut, and it appears that an empress with her three daughters, who had been cast into the sea, are embodied in the tree.[119] On the Slave Coast of West Africa the negroes tell how from the mouldering bones of a little boy, who had been murdered by his brother in the forest, there sprang up an edible fungus, which spoke and revealed the crime to the child’s mother when she attempted to pluck it.[120]
