Tree Worship
Tree-Worship probably arose from the conception that trees were the residences or embodiments of spirits or deities. Sir John Lubbock believes that it was general to most of the great races of mankind at a certain stage of mental development. Fergusson's Tree and Serpent Worship, and Tylor's Primitive Culture are the best authorities on the subject.
