"I don't think anything in nature just 'happens so,' Davy, and I am sure that the bee's work for the flower doesn't, for there are too many flowers that would have no seed and would die out if it were not for the bees that carry the pollen, and most of these flowers have grown just to fit in every way the especial little bee, or big bee, or insect, that comes to work for them. There are some flowers, like the sweet-pea, that the bee cannot get into without getting pollen on his legs, and there are others that drop it upon his back. Some flowers have stamens that wither before the pistil is ready for the pollen. In such flowers the little servants go from one to the other—from a new flower to an old one—carrying the pollen which would not be of any use in the flower where it grew."
"And is that really all that the flower's pretty color and sweet smell and delicious honey are for?" asked little Prue, "just to get bees to work for it?"
"No, Prue, I don't think so. I think all the world of nature is harmony, like sweet music, and the flowers with their beauty and sweetness are part of it, but I think that just as we may attract friends and good servants by kindness and offering something in return, so the flowers attract the bees and butterflies, and even a little girl and boy to keep the weeds away. The more a flower depends on an insect to carry its pollen, the gayer or sweeter that flower always is. The orchids, which are almost the finest flowers in the world, seem to be made especially for the insects, and they could not do without them, any more than the insects could do without the flowers."
"And is that what makes some flowers such funny shapes, too?"
"I think it is. The foxglove, and the horse mint, and many others, have curious shapes and forms, just to fit their little helpers, and the milkweed has a funny little saddle-bag which it hangs to the bee's feet, so that he can carry it to another plant. There is another kind of a milkweed which is very cruel, for it attracts small insects by its odor, and when they come they are caught by a sticky substance and held until the weed sucks them down and really eats them, much as we eat our food. So, you see, plants are a good deal like people, just as I told you the other day."
"You said they could sleep, too."
"Yes, your rose-moss closes up every night, shuts its eyes just as you do, and rests. Many flowers close at night, and some even droop their heads quite low, like the bird, which sleeps with its head beneath its wing."
