Several species of evergreens have already been studied. These should be reviewed, and representatives of other species examined. Mid-winter is most suitable for the study of evergreens. The following points should be considered: 1. Description leading to identification 2. Nature of soil and water conditions 3. Common uses of each species of evergreen 4. Collection of wood specimens and cones. WOOD SPECIMENS Specimens should be uniform in size and should show bark on one side and heart wood as well as the outside, or sap wood. They should be about six inches long, two inches wide on the side having the bark, and should gradually come to an edge toward the pith, or centre. When seasoned, one side and one edge should be polished and then oiled or varnished. Specimens of the wood of the deciduous trees may also be prepared during the winter. FRUITS During the winter months, some time should be devoted to reading and discussing articles on general farming and fruit growing. Such articles may be taken from books, magazines, or newspapers, and may be supplied partly by the teacher and partly by the pupils. These articles will be appreciated by the pupils all the more because of their studies of fruit trees during the season. Such topics as the following may be discussed: 1. Best kind of apples, plums, bush fruits, and strawberries. Reports from the Dominion and Provincial Departments of Agriculture. 2. Method of raising fruit trees--from seed, grafting, and budding. 3. Demonstrations in pruning. This may be done in early spring by taking a class to a neighbouring orchard. 4. Methods of planting and cultivation. 5. Packing and storing. 6. Spraying. Much information is to be found in Horticultural Journals and papers, and in Bulletins to be obtained from the Secretary of Agriculture for Ontario. Illustrated articles on gardening and fruit growing should be collected for school use. Views of fine gardens, parks, and home grounds will be of interest to the pupils. Simple artistic methods of ornamental planting with trees, shrubs, vines, and herbaceous perennials can now be introduced, and some scheme for improving the school grounds outlined. Catalogues should be obtained soon after New Year's and, after examining their merits, the best varieties of seed and fruit for the district should be selected. Horticultural societies, as well as Dominion and Provincial Departments of Agriculture, commonly give selected lists with descriptions of the different varieties. WEEDS AND WEED SEEDS The training in the observation and identification of weeds and weed seeds, which was begun in Form III, should be continued in Form IV. For method see Form III. PHYSICAL SCIENCE PHASE OF NATURE STUDY WATER PRESSURE 1. Grasp an empty tin can by the top and push it down into a pail of water. Note the tendency of the can to rise. The water presses upward. Its downward pressure is evident.
