Compare the plants that are crowded, with others of the same kind that are not crowded. Compare the rate of growth of the plants in a plot that is kept hoed and raked with the rate of growth of plants in a neglected plot. BULB PLANTING The planting of bulbs in pots for winter blooming should be commenced with pupils in Form I and continued in the higher Forms. As a rule, the potted bulbs will be stored and cared for in the home, as most school-rooms are not heated continuously during the winter. Paper-white narcissus and freesia are most suitable and should be planted about the fifteenth of October, so that the plants will be in bloom for Christmas. LESSON ON BULBS AND BULB PLANTING ~Materials.~--The bulbs to be planted. As many four-inch flower-pots or tomato cans as are required. Soil, composed of garden loam, sand, and well-rotted manure in equal proportions. Stones for drainage. Sticks for labels (smooth pieces of shingle, one and a half inches wide and sharpened at one end, will answer). Pictures of the plants in bloom. ~Observations.~--The attention of the pupils is directed to the bulbs, and they are asked to describe the size, form, and colour of each kind of bulb. A bulb is cut across to make possible the study of the parts, and the pupils observe the scales or rings which are the bases of the leaves of the plant from which the bulb grew. The use of the fleshy mass of the bulb as a store of food for the plant that will grow from it is discussed. The sprout in the centre of the scales with its yellowish-green tip is observed, and its meaning inferred. The picture is shown to illustrate the possibilities within the bulb. PLANTING THE BULB The teacher directs, but the work is done by the pupils, and the reasons for the following operations are developed: What is the use of the one-inch layer of pebbles, or broken brick, or stone, that is placed in the bottom of the pot? Why are the bulbs planted near the top of the soil? Why is the soil packed firmly around the bulbs? Why must the soil be well wetted? Why is the pot set in a cool, dark place for a month or more?
