apples and anything else which may be in bloom, 
but will go miles to find orange trees; or if it starts 
on onions, then the geraniums and the carnations 
and the poppies have no attraction for it. 
Which, by the way, is the reason that the bees 
produce, for themselves and for us, clover honey, 
and orange honey, and onion honey, each with a 
distinct flavor of its own. 
But there are other reasons why the flowers do 
not get mixed up. 
One is that while some flowers advertise to the 
bees, others advertise only to the humming birds 
—the bees can not get into the bird flowers and 
the birds can not get into the bee flowers; some 
flowers open in the early morning, and some 
toward noon; some bloom in April, and some in 
July. 
The pollen granules of some flowers are so 
large that they can not push their tubes down into 
the egg nests of flowers with small pistils; there 
are structural differences between the various 
families of plants which seem to make cross 
pollenation almost impossible; and so on through 
a wide range of reasons why certain plants are
