_To the teacher._--The leaves of the plants named are quite noticeably so placed on the plants, have such relations to one another, and are of such outline that they present the greatest possible surface to the _air_ and _sunshine_ and _rain_. The leaf stalk and midrib and veins are stiff and strong to keep the leaves spread out. Compare with the ribs of an umbrella. The benefit of sunshine to leaves and plants can be developed by discussing with the pupils the paleness and delicateness of plants that have been kept in a dark place, such as in a dark cellar. They are also acquainted with the refreshing effect of rains upon leaves. The use of air to the leaves is not so easy to develop with pupils of this age, but the use of air for breathing just as boys and girls need air for breathing may be told them. CLASS-ROOM LESSON ON LEAVES ~Introduction.~--Tell me all the things that you know upon which leaves grow. On trees, bushes, flowers, plants, vegetables, etc. Are leaves all of the same shape? To-day we are going to learn the names of some of the shapes of leaves. ~Observations.~--Show the class the heart-shaped leaf of catalpa or lilac, and obtain from the pupils the name _heart-shape_. Use the following types: Maple leaf as star-shape, Grass or wheat or corn as ribbon-shape, Nasturtium or water-lily as shield-shape, Ash or rowan, as feather-shape. ~Drill.~--Pupils pick out the shape named. Pupils name the plant to which each belongs. Which shape do you think is the prettiest? GARDEN STUDIES If the pupils of this Form have planted and cared for garden plots of their own, they will have a greater love for the flowers or vegetables that grow in them than for any others in the garden, because they have watched their development throughout. For them such continuous observation cannot but result in a quickening of perception and a deepening of interest and appreciation. STUDIES IN THE PUPIL'S INDIVIDUAL PLOT What plant is the first to appear above ground? What plant is the last to appear? Describe what each plant was like when it first appeared above ground. What plants grow the fastest? What effect has cold weather, warm weather, dry weather, on the growth of the plants? What weeds grow in the plot? Why do these weeds obstruct the growth of the other plants? What kind of root has each weed? Find out what kind of seeds each weed produces? Why is each weed hard to keep out of fields? What garden plants produce flowers? How are the seeds protected? Compare the seeds with those that you planted. Select the seeds of the largest plants and finest flowers for next year's seeding. STUDIES FROM THE GARDEN AS A WHOLE What plants grow tallest? What plants are most suitable for borders? What plants are valuable for their flowers? What plants are valuable for their edible roots, for their edible leaves, for their edible seeds? How are the edible parts stored for winter use?
