COLLECTION OF WOOD SPECIMENS
During the winter months the boys may prepare specimens of wood for the school collection. These specimens should be cut green and dried. They should be uniform in length—not more than six inches—and should show the bark at one side. The side showing the bark should be two inches wide at most, six inches long, and running in a V-shaped, radial section toward the pith. A tangential section also shows well the annual layers. A piece of slab as cut lengthwise off a round stick is tangential. Also visit wood-working factories for specimens of rare or foreign woods. In securing these specimens, care should be taken not to mutilate trees.
