"Come to me, and I will give you honey, if you will bring me pollen dust in exchange."
If you watch the different kinds of grasses, sedges, and rushes, which have such tiny flowers that you can scarcely see them, you will find that no insects visit them. Neither will you ever find bees buzzing round oak trees, elms, or birches. But on the pretty and sweet-smelling apple blossoms you will find bees, wasps, and other insects.
The reason of this is that grasses, sedges, rushes, and oak trees have a great deal of pollen dust. As the wind blows them to and fro it wafts the dust from one flower to another. And so these plants do not need to give out honey, or to have gaudy or sweet-scented flowers to attract insects.
But the brilliant poppy, the large-flowered hollyhock, the flaunting dandelion, and the bright blue forget-me-not,—all these are visited by insects, which easily catch sight of them and hasten to sip their honey.
We must not forget what the fragrance of the flowers can do. Have you ever noticed the delicious odor which comes from beds of mignonette, mint, or sweet alyssum? These plants have found another way of attracting the insects; they have no need of bright colors, for their fragrance is quite as true and certain a guide. You will be surprised if you once begin to count them up, how many dull-looking flowers are sweet-scented, while some gaudy flowers have little or no scent. Still we find some flowers, like the beautiful lily, the lovely rose, and the delicate hyacinth, which have color and fragrance and graceful shapes all combined.
But there are still other ways by which flowers secure the visits of insects. Have you not observed that different flowers open and close at different times? The daisy receives its name "day's eye" because it opens at sunrise and closes at sunset, while the evening primrose spreads out its flowers just as the daisy is going to bed.
What do you think is the reason of this? If you go near a bed of evening primroses just when the sun is setting, you will soon be able to guess. They will then give out such a sweet odor that you will not doubt for a moment that they are calling the evening moths to come and visit them. The daisy, however, opens by day and is therefore visited by day insects.
Again, some flowers close whenever rain is coming. Look at the daisies when a storm is threatening. As the sky grows dark and heavy, you will see them shrink and close till the sun shines again. They do this because in the center of the flower there is a drop of honey which would be spoiled if it were washed by the rain.
And now you will see why the cup-shaped flowers so often droop their heads,—think of the snowdrop, the lily-of-the-valley, and a host of others. How pretty they look with their bells hanging so modestly from the slender stalk! They are bending down to protect the honey within their cups.
We are gradually learning that everything which a plant does has its meaning, if we can only find it out. And when we are aware of this, a flower garden may become a new world to us if we open our eyes to all that is going on in it. And so we learn that even among insects and flowers, those who do most for others receive most in return. The bee and the flower do not reason about the matter; they only live their little lives as nature guides them, helping and improving each other.
I have been able to tell you but very little about the hidden work that is going on around us, and you must not for a moment imagine that we have fully explored the fairy land of nature. But at least we have passed through the gates, and have learned that there is a world of wonder which we may visit if we will. And it lies quite close to us, hidden in every dewdrop and gust of wind, in every brook and valley, in every little plant and animal.
