The object of this year's work may be the teaching of the value of earth, air, light, and water upon plants. _Fall work._--Experiments to show these to be carried on in schoolroom. Experiments to show value of earth to plants: (1) Plant seeds in fertile earth; poor earth; clean sand or sawdust. (2) Plant seeds in sawdust and on cotton batting placed on water in a jar. Experiments to show use of light to plants: (1) Sow seeds in two boxes of earth prepared just alike. Place one in the window, one in a dark closet, and note results. (2) Place house plants from greenhouse in a window, and note change of position of leaves. (3) The story of the sunflower. Experiments showing use of water to plants: (1) Place a very much wilted cut plant in water, and note result. (2) Place seeds in earth which is dry, and in earth which is kept moist. (3) Plant seeds on batting floating on a tumbler of water, and note results. These experiments should extend over several weeks.
