INJURIOUS AND BENEFICIAL INSECTS AND BIRDS: Identification of common insects and observations on their habits; means of combating such insects, as codling moth, etc.; bird identification, and study of typical members of some common families, as woodpeckers, flycatchers; spiders. (See pp. 217-22 and 240-5.) ORNAMENTAL AND EXPERIMENTAL GARDEN PLOTS: Observations and conclusions based upon experimental plots; common shrubs, vines, and trees, and how to grow them. (See pp. 225-30 and 279.) FUNCTIONS OF PLANT ORGANS: Simple experiments illustrating roots as organs of absorption, stems as organs of transmission, and leaves as organs of respiration, transpiration, and food building. (See pp. 273-8.) ECONOMIC STUDY OF PLANTS: Comparative study of varieties of winter apples, of fall apples, or of other fruits of the locality; visits to orchards; weed studies continued. (See Form III.) (See pp. 229-30 and 239-40.) RELATION OF SOIL AND SOIL TILLAGE TO FARM CROPS: Soil-forming agents, as running water, ice, frost, heat, wind, plants, and animals, and inferences as to methods of tillage. (See pp. 268-70.) WINTER AIR AND LIQUID PRESSURE: Simple illustrations of the buoyancy of liquids and of air; simple tests to demonstrate that air fills space and exerts pressure; the application of air pressure in the barometer, the common pump, the bicycle tire, etc. (See pp. 248-52.) OXYGEN AND CARBON DIOXIDE: Generate each of these gases and test for properties, as colour, odour, combustion, action with lime-water; the place occupied by these gases in nature. (See pp. 252-5.) PRACTICAL APPLICATION OF HEAT, STEAM, AND ELECTRICITY: Making a simple voltaic cell, an electro-magnet, and a simple electroscope. Test the current by means of the two latter and also with an electric bell. Explain the application of the above in the electric telegraph and motor. Simple demonstration of pressure of steam; history and uses of the steam-engine. (See pp. 259-60.) SPRING INJURIOUS AND BENEFICIAL INSECTS AND BIRDS: Identification of noxious insects and observations thereon; study of representatives of common families of birds, as thrushes, warblers, sparrows; economic values of birds. (See pp. 283-5 and 286-7.) AQUATIC ANIMALS: Observation exercises upon the habits, movements, and structures, including adaptive features of aquatic animals, as crayfish, mussel, tadpole, etc. (See pp. 285-6.) ORNAMENTAL AND EXPERIMENTAL GARDEN PLOTS: Experimental plots demonstrating the benefits of seed selection; ornamental plots of flowering perennials and bulbous plants; how to improve the school grounds and the home lawns. (See pp. 270-3 and 263-5.) TREE STUDIES: Comparison of the values of the common varieties of shade trees, how to plant and how to take care of shade trees. (See pp. 280-2.) THE FUNCTIONS OF PLANT ORGANS: Examination of the organs of common flowers; use of root, flower organs, fruit, and seed. (See pp. 273-8.) ECONOMIC STUDY OF PLANTS:
