_To the teacher._--When pupils who are absent find it impossible to give the necessary attention to their garden plots at school, they should turn them over to other pupils or to the teacher, who may at his own discretion use the produce for purposes of general garden revenue.
SEED GERMINATION
The seeds for the garden should be purchased quite early in the spring.
As the planting of poor seed is often the cause of much disappointment, it is well to test the germinating power of the different varieties to be planted. The pupils of this Form should test especially those varieties which they have chosen. To do this, place about twenty-five seeds in a germinating dish, which may be made as follows: Take a deep plate, such as a soup plate, fill it about half full of moist sand, and spread over this a piece of moist cloth. Put the seeds upon this cloth and cover them with a second piece of damp cloth or moss. To prevent drying out invert over it another plate and set all in a warm dry place (about 70 to 80 degrees F.). After a few days count the number of seeds that have germinated. This will be a guide in planting as to how thick the seed should be sown.
The pupils should watch the development of germinating grains, such as corn and beans, germinated in the same way as in the last exercise. The following points may be observed:
1. The first change noticed. (Swelling of the seed)
2. The appearance of a growing shoot and its direction. (Root)
3. The second shoot and its direction. (Stem)
4. The appearance of the first pair of leaves.
5. The appearance of root-hairs and rootlets.
6. What becomes of the main body of the seed.
7. How the second pair of leaves differs from the first pair.
8. Length of time required to produce the first pair of leaves.
Pupils may be taught the conditions that are necessary for the germination of seeds by means of a few simple experiments which can be carried on in the school-room.
1. In February, plant a few seeds of the pea, or oat, or wheat, in a box of soil, and place the box outside the school window.
2. In April, plant a few seeds similar to those used in No. 1, in a box of perfectly dry soil, and set the box inside the school window.
3. Plant a few seeds similar to those used in No. 1, in a jar containing soil that is kept very wet, and set the jar in the school window.
4. Plant a few seeds, similar to those used in No. 1. in a box containing soil that is moist but not wet, and set the box in the school window.
5. Plant seeds as in No. 4, except that the box is kept in a dark cupboard.
Compare the results of the above with reference to:
1. The number of seeds that germinate.
2. The growth and condition of the plants.
Form conclusions with reference to:
1. The conditions that are required for seed germination.
2. The benefits of well-drained soil.
Pupils make drawings showing the boxes and plants.
PLANTS FOR INDIVIDUAL PLOTS
The pupils of this Form should not attempt to grow more than two varieties of flowers and two of vegetables. Of flowers, mixed asters and Shirley poppy are to be recommended, the poppy being an early blooming flower and the aster late blooming. Carrots and radishes are desirable vegetables, as the carrot matures late and the radish early. Two or three crops of radishes may be grown on the same ground in one season.
Besides these, a few others should be chosen for special study, such as the potato, onion, corn, and sunflower.
STUDIES BASED ON OBSERVATIONS OF GROWING PLANTS
Attention should be given to the growing habits of plants, the size and rate of development, the method of multiplying and propagation, and the part used for food. The potato is a tuber which is nothing more than the swollen end of an underground stem; the onion a bulb composed of the bases of thickened leaves; the corn an example of a jointed stem or gra.s.s having two kinds of flowers, the ta.s.sels being the staminate flowers and the cob with its silk the pistillate ones; the sunflower an example of a compound flower made up of many little flowers each of which produces a single seed.
Observations should also be made upon the progress in germination of the nuts and other tree seeds collected in the fall. When the seeds fall from the elms and soft maples in the spring, some of them should be collected and planted in the forestry plot, or nursery.
PLANTING AND CARE OF SWEET-PEAS
1. Sow as early as possible in spring.
2. Sow on well-drained land and never in the shade or near gra.s.s. Gra.s.s roots rob the sweet-pea roots of water.
3. Use a small amount of fertilizer--well-rotted manure spaded deeply into the soil. This is best done in the autumn.
4. Make the trench in the fall about five or six inches deep.
5. Plant in a trench in April from half an inch to an inch apart.
6. Cover from three inches to four inches deep.
7. Water thoroughly once or twice a week, and have the soil lower along the row than farther out, so as to hold the water.
8. Put a mulch of lawn clippings along the row on each side to prevent drying out.
WILD FLOWERS
Arrange an excursion to the woods when the spring flowers are in bloom.
Keep a flower calendar, showing:
1. The date when a plant was first found in bloom
2. The name of the plant
3. Place where found
4. Name of the pupil who found it.
When in the woods discuss the following points:
1. Why these wild flowers come into bloom so early in spring. They have a large supply of food stored up from the previous summer.
2. Dig down with a trowel or heavy knife and find this storehouse of food. It may be in the form of bulb, corm, or rhizome.
