Well ripened, or properly cooked, they are readily digested by the average stomach; though some delicate digestions have difficulty with them.

They contain a fair amount of acids, and from five to seven per cent of sugar.

Their general wholesomeness and permanent usefulness may be gathered from the fact that they are one of the few fruits which you can eat almost daily the year round, or at very frequent intervals, without getting tired of them.

Food that you don't get tired of is usually food which is good for you.
Dried apples are much inferior to the fresh fruit, because they become toughened in drying, and because growers sometimes smoke them with fumes of sulphur in the process, in order to bleach or whiten them; and this turns them into a sort of vegetable leather.

Next in usefulness probably come pears, though these have the disadvantage of containing a woody fibre, which is rather hard to digest, and they are, of course, poorer "keepers" than apples.
