Some of these apples are sound and solid on the inside, but they have hard blackish spots on the outside ([Fig. 307]). This is a disease—the apple-scab. This scab is caused by minute plants and these plants also claim the apple as their own. There are ways by means of which the apple-grower is able to destroy the codlin-moth and the apple-scab; and thereby he secures fair and sound apples.
Insects and diseases and men are all fighting to own the apple.

2. How many parts or compartments are there in the core?
3. How many seeds are there in each part?
