3. The blooming of the spring flowers in the woods before the leaves of the trees reach their full development, thus taking advantage of the sunlight.

4. Mark a few clumps or individual plants and visit them again after a month. Look for the growing fruit with its seeds.

5. The leaves of the hepatica seen at the time when the blossoms appear are leaves which grew the previous season. Dig up a plant and notice the new leaves starting.

6. The kind of soil each seems to grow best in and the amount of light it receives.

7. Have the pupils examine the flowers and leave them growing. They should gather a few for the school-room.

8. Have the pupils write a short account of their visit to the woods.

Have them make drawings of the different flowers collected.

Dig up a few specimens of wild flowers and transplant in a shady corner in the grounds or school garden. The following varieties are suggested for special observation and study: hepatica, violet, anemone, columbine, Indian turnip, marsh marigold.

Teach one or two lessons on wild flowers, similar to the lessons ill.u.s.trated for the nasturtium.

WEEDS

Pupils in this Form should learn to identify most of the weeds that are found in the garden plots and a few of those commonly found in fields and along roadsides. The large bulletin _Farm Weeds_, published by the Dominion Department of Agriculture, will be of great value in helping to identify the weeds and also in gaining useful information regarding them and the best means of eradicating them.

The following species are recommended for special study during the season: mustard (such varieties as are found in the vicinity), Canada thistle, purslane, lamb's quarter, pink-rooted pigweed, and quack gra.s.s.

The pupils should be familiar with the general appearance of the plant; its appearance when coming up in the spring; whether annual, biennial, or perennial; nature of the root, and whether hard to pull up; if hard to eradicate, why so; its rate of growth compared with the garden plants; the number of seeds produced by a single plant; how the seeds are scattered.

THE APPLE TREE

(When the buds are beginning to open)

FIELD EXERCISE

The pupils, during an excursion that is conducted by the teacher or while making individual observations, obtain answers to problems of the following type:

What is the shape of the top of the apple tree?

Are all apple trees of the same shape?

What is the height of the trunk?

Measure the girth of the trunk of the largest?

Are the leaf buds and flower buds more numerous near the inside of the tree top or more numerous at the outer part of the top?

_To the teacher._--When discussing the answers to the above problems, develop the conception of the convenience of the low stature of the tree for gathering the apples, of the wide-spreading branches for bearing a large crop, of the stoutness of the trunk for supporting the weight, and also of the position of the buds as adapting them for securing sunshine.

CLa.s.s-ROOM LESSON ON THE APPLE TREE

~Materials.~--Twigs bearing flower and leaf buds. These are gathered by the pupils from the apple trees that were studied during the field exercises.

Each pupil finds on his twig the objects and markings, etc., as in the following outline:

Describe the shape of the twig.

Where were the apples that grew last year attached?

Describe the positions of the buds on the twigs.

Which buds are the larger, those at the end or those on the side of the twig?

Describe the condition of the bud scales.

Open the buds and find what they contain.

Of what use are the bud scales?

How many blossoms are in one bud?

Of what use to the young leaves is the downy covering?

FIELD EXERCISE FOLLOWING CLa.s.s-ROOM LESSON

(Just after the blossoms are fully open)

What is the colour of the apple blossom?

Find the little green cup on which the petals rest.

Describe the cup.

Find the other things that are on the rim of, or that are within, the cup. What are they?

What insects visit the flowers?

Does the cup fall off when the petals fall?

Does the cup close up as soon as the petals fall?

What does the green cup grow to be?

_To the teacher._--Apple trees have somewhat round or pyramid-shaped tops, varying in detail with the variety of apple tree. The twigs are short and usually crooked. The fruit twigs are called spurs. The buds at the ends of the twigs and spurs are the largest and contain both leaves and blossoms, and there are usually several blossoms in each bud. The bud scales burst apart and drop off as the leaves and blossoms develop.

The side buds produce leaves only. The petals and pollen boxes are borne on the rim of the green cup, and inside the cup are found the five tips of the seed cases. When the petals drop off, the rim of the cup remains spread out for a short time. This is the proper time for spraying, so that the cup may hold a drop of poison to kill the tiny worms which cause apples to be wormy. It is the green cup that grows and forms the flesh of the apple.

Orchard trees suitable for lessons for Form II are apple, plum, pear, peach, and cherry.
