Trees

He who wanders widest lifts
No more of beauty's jealous veils,
Than he who from his doorway sees
The miracle of flowers and trees.

Whittier.

The trees of the forest are of two classes, deciduous trees and evergreen trees. To the former belong those which shed their leaves in the fall, are bare in the winter, and then grow a new crop of leaves in the spring, e.g., oaks, elms, maples. The evergreen trees shed their leaves also, but not all at one time. In fact, they always have a goodly number of leaves, and are consequently green all the year round, e.g., pines, spruces, firs.

The uses of wood are so many and various that we can only begin to mention them. In looking about us we see wood used in building houses, in making furniture, for railroad ties, and for shoring timbers in mines. In many country districts wood is used for fuel. And do you realize that only a short time ago the newspaper which you read this morning and the book which you now hold in your hand were parts of growing trees in the forest? Paper is made of wood-pulp, mostly from Spruce.
