EXAMINATION of the cross-section of a tree-trunk shows the following details of structure: Covering the trunk is the corky bark, the outer layers of which serve to protect the trunk from extreme variations of temperature and humidity, and from mechanical injury; the inner layers, called the bast, serve to conduct the food manufactured by the leaves to actively-growing parts of the wood and to places of food-storage in the tree. The bark and the bast together form the rind.
