_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.

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. [Illustration: CHRISTMAS FERN An evergreen fern growing in woods and rocky places. Range: Eastern United States and Canada. Photograph by Mary C. Dickerson.] Besides the direct uses of wood, we turn to the forest for many interesting and valuable products, varying in importance from a balsam-pillow filled with the fragrant leaves or needles of the Balsam Fir, to turpentine and rosin (naval stores), produced chiefly by the Long-leaved Pine of the Southeastern States. Spruce gum is obtained from the Black Spruce and Red Spruce. Canada balsam used in cementing lenses together in microscopes, telescopes, and the like, comes from the Balsam Fir. Bark for tanning comes from Oak and Hemlock. The Indians of the Eastern Woodlands or Great Lakes area made canoes and many other useful articles of the bark of the Canoe or Paper Birch. Baskets are made from Willow twigs. Maple sugar comes chiefly from the Sugar Maple. [Illustration: IN A TURPENTINE GROVE The long-leaved Pine furnishes most of the turpentine and rosin of commerce.
