secretions of the leaves, and the blood extracted from it. There is,
however, one difference between the digesting powers of the leaves
when exercised upon insects or upon meat. Even if the bodies of
insects have become putrid, the plant, as has already been stated, has
no difficulty in assimilating them; but as regards meat, it is only
when it is perfectly sweet that the secretions of the leaves will act
upon it.

The pitcher plant undoubtedly derives its principal nourishment from
the insects it eats. It, too--unlike most other carnivorous plants,
which, when the quantity of food with which they have to deal is in
excess of their powers of digestion, succumb to the effort and
die--appears to find it easy to devour any number of insects, small or
large, the operation being with it simply a question of time. Flies,
beetles, or even cockroaches, at the expiration of three or four days
at most, disappear, nothing being left of them save their wings and
other hard, parts of their bodies.

The _Sarracenia_ is, indeed, not only the most voracious of all known
species of carnivorous plants, but the least fastidious as to the
nature of the food upon which it feeds.--_W.C.M., Nature._
