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.
BIRD STUDY
