The ancient conception of human trees can be traced in the superstitious endeavours of ignorant peasants to get rid of diseases by transferring them to vicarious trees, or rather to the spirits who are supposed to dwell in them; and it is the same idea that impels simple rustics to bury Elder-sticks and Peach-leaves to which they have imparted warts, &c. The recognised analogy between the life of plants and that of man, and the cherished superstition that trees were the homes of living and sentient spirits, undoubtedly influenced the poets of the ancients in forming their conceptions of heroes and heroines metamorphosed into trees and flowers; and traces of the old belief are to be found in the custom of planting a tree on the birth of an infant; the tree being thought to symbolise human life in its destiny of growth, production of fruit, and multiplication of its species; and, when fully grown, giving shade, shelter, and protection. This pleasant rite is still extant in our country as well as in Germany, France, Italy, and Russia; and from it has probably arisen a custom now becoming very general of planting a tree to commemorate any special occasion. Nor is the belief confined to the Old World, for Mr. Leland has quite recently told us that he observed near the tent of a North American Indian two small evergreens, which were most carefully tended. On enquiry he found the reason to be that when a child is born, or is yet young, its parent chooses a shrub, which growing as the child grows, will, during the child’s absence, or even in after years, indicate by its appearance whether the human counterpart be ill or well, alive or dead. In one of the Quādi Indian stories it is by means of the sympathetic tree that the hero learns his brother’s death. In the middle ages, the old belief in trees possessing intelligence was utilised by the monks, who have embodied the conception in many mediæval legends, wherein trees are represented as bending their boughs and offering their fruits to the Virgin and her Divine Infant. So, again, during the flight of the Holy Family into Egypt, trees are said to have opened and concealed the fugitives from Herod’s brutal soldiery. Certain trees (notably the Aspen) are reputed to have been accursed and to have shuddered and trembled ever after on account of their connexion with the tragedy of Calvary; while others are said to have undergone a similar doom because they were attainted by the suicide of the traitor Judas Iscariot.
