92 ANIMAL ACTIVITIES. 
If you examine a head of the common white clover, 
so abundant everywhere, you will see a part of the tiny 
flowers of which the head is composed standing erect 
and looking their best and prettiest. These are the 
flowers not yet visited by the bees; the dry and 
withered flowers hanging down near the stem have 
been fertilized, and each one now contains a pod in 
which the tiny clover-seeds are ripening. 
Not only do we find the proboscis of an insect fitted 
in structure for the plant on which it habitually feeds, 
but we find the plants, also, ordering their ways to 
conform to the habits of their insect friends. Thus, 
stamens grow in such a way that they must dust 
their pollen on the insect as he reaches the honey-cup, 
while stigmas reach out in their growth to occupy at 
maturity a position in the pathway of the pollen-laden 
insect. Not only do stamens and stigmas seek the 
insect, but the petals call their friends by color-signs 
and point out by brilliant lines the direction of the 
honey-cup, while hostile barbs and pointed hairs below 
the cell of nectar prevent the approach of honey-loving 
ants and small insects not useful to the plant.
