Lesson the common seed bearing plant such as a grass consists of four major parts: root, stem, leaf and 4 flower. The Root

Depth of Planting Seeds. No definite rules can be given regarding the depth to plant seeds of various kinds. The size of the seed, the kind of soil, and the amount of moisture in the soil should be considered. Large seeds are planted deeper than small seeds, although it does not follow that the largest seeds should be planted the deepest. On light soils such as fine sand or sandy loams, seeds are planted to a greater depth than on heavy soils. The more moisture there is present in the soil, the less need there is for deep planting. For this reason seeds are usually given a relatively light covering in the spring. The same kind of seeds planted in late summer requires greater covering because the surface layer of soil is usually drier and it is necessary to place the seed at a greater depth to obtain sufficient moisture to ensure germination.
Thinning. This is an important operation when seeds are planted. Thinning may be made a process of selection. The weakest plants should be discarded and the strongest left to grow. By thinning, a uniform stand is secured, but as this is a tedious and expensive operation, gardeners try to avoid it as much as possible by planting the proper quantity of seed and distributing it evenly. In the case thinning is delayed too long plants that are to be left become weak. Thinning should be done as soon as there is reasonable assurance that the plants left will not be killed by unfavorable weather conditions, or destroyed by insects that are injurious during the early stages of the plant growth.

LESSON 57

TEXT: APPLES

The early history of the domestic apple becomes lost in antiquity. The apple probably originated in the regions of the Caucasus. It has existed in Europe, both in wild and in cultivated forms, from time immemorial.
The commercial varieties of today are far removed from the wild apples from which they developed over a period of many hundreds of years. Apples are grown and may be grown in many regions and are an important crop. All together, the apple, pear and quince constitute the pomes or pomaceous fruits. The kinds of pome fruits listed other than apples and pears, are of minor importance as they are rarely produced except for special purposes.
TEXT:ORCHARD LOCATIONS AND SITES
The location has to do with the relative distance from town, city, home, highway or some other established place. Sites in contrast refer to elevation, topography, bodies of water and other factors that may effect the growth and fruiting of the trees. A poor location or site is certain to be an enduring handicap while good ones enable the grower to attain his goal.
