In November or December make a study of Canadian evergreens, choosing spruce, balsam, and cedar if available. The pupils should learn to distinguish the different species by an examination of the leaves, buds, arrangement of branches, bark, seeds, and cones. The age of young trees can be determined by noting the successive whorls of branches. In this way also the age of the leaves may be determined. On some trees the leaves persist for seven or eight years. Evergreens are frequently used as Christmas trees and their branches for house decorations. On which species do the leaves persist longest? How do they compare with the pines? The leaves are always as old as the wood upon which they grow.
Have the pupils notice how the small leaves and horizontal branches resist the clinging of snow in winter. Each branch bends down enough to cause the snow to slide off on to the one next below, and so on, until it reaches the ground. The conical shape of the tree also facilitates this action of dislodging the snow. They will also notice that these trees are well adapted to withstand wind, as the top part, which is most exposed to the wind, is much smaller and more pliable than the part next the bottom. The gum, or resinous covering, of the buds protects them from injury by rain or snow. Some kinds of pine, such as the pitch pine, have a great abundance of gum and turpentine. Resin and pine tar are made chiefly from this species. Heat a piece of pine wood—a knot or root is best. The gum will be seen oozing out of the wood. Pine torches were much used in the early days of settlement in Canada. Examine the gum "blisters" in the bark of the balsam tree. From this source the "Canada Balsam" gum of commerce is taken. The gum and resin in the wood and bark help to preserve the wood from decay.
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.
RELATED READING
Winter is nature's quiescent period. Continuous active observation out-of-doors among the plants of the forest and garden gives place for a time to indoor work and reflection. Pupils need time for reading and reflection, and no time is so opportune as the quiet winter season. During these months some time should be devoted to the reading of nature stories and extracts from magazines and books dealing with plant as well as animal life. Pupils should review their gardening experiences and discuss plans of improvement for the approaching spring and summer. Let them write letters to the Form II pupils of other schools where similar work has been carried on, giving some of their experiences in gardening and plant and animal studies. A certain Friday afternoon might be appointed for hearing the letters read which have been received in reply. Suitable short poems that have a direct bearing upon their outdoor studies should be read from time to time. Good pictures come in here also as an aid in helping the children to appreciate written descriptions. The first-hand observations made by the pupils will form a basis for the better and more appreciative interpretation of these literature selections.
THE DOG
CLASS-ROOM LESSON
Use the conversation method, since this is an animal that is well known to all the pupils. By natural, easy conversation with the pupils, encourage them to tell what they know about the usefulness and the other qualities of their canine friends.
The pupils know that some dogs are useful for hunting wild animals, others for driving or herding cattle and sheep, others for guarding their master's property, others for hauling sleighs and wagons, while others are of use as pets or playfellows.
