CHAPTER XIII
THE FOOD QUESTION
.
THE relations of shes to one another and to,” the other
Ÿj
forms of life which serve them
constitute an
portant part of their biology.
Strange as it may seem,
of the most interesting facts brought out by recent investigà?
tions is _'_that shès may
not get enough to eat and their
growth is accordingly seriously aected. Owing to the
_'Ï;
natural law Of increase there seem too many of them, and
from yarious
we may conclude that man is able to
inuence their abundance, in some cases at any rate.
HOW
'
shes obtain their food, its nature, and the part taken by
man in regulating their numbers Will be the subject
present chapter.
