In the case of a large tree covered with innumerable flowers, it may be objected that pollen could seldom be carried from tree to tree, and at most only from flower to flower on the same tree; and flowers on the same tree can be considered as distinct individuals only in a limited sense.
The act is based on the procreative law of nature. Plant-breeding is simply accomplished by sifting the pollen of one plant upon the stigma of another, this act pollenation resulting in fertilization, Nature in her own mysterious ways bringing forth the new plant.
In many cases this is assured by the pollen-bearing flowers and stigmatic flowers being entirely distinct, as in cucumbers and Indian-corn; perhaps on different plants, as in the palms and willows; again by the pollen maturing and disseminating before the stigma is mature, as already mentioned, and vice versa.
Let us examine it closely. If we pluck one of the blossom's heads and keep it in a vase over-night, we shall probably see on the following morning a tiny yellow ring of pollen encircling the outer edge of the cone. In this way only are we likely to see the ring in its perfection, as in a state of nature the wind and insects rarely permit it to remain.
Some one remarked that in the case of Berber, born of a simple country woman and her uneducated husband, this was impossible. Another man laughed. "Berber may be a Martian, or perhaps he was originally destined to be the first man on Jupiter. He took the wrong car and landed on this globe. Why not? How do we know what agency carries pollen of human life from planet to planet?"
Of course it was here before the honey-bee, and has been evolved quite independently of it. It feeds upon the pollen and nectar of flowers like the true bee, and is, therefore, of similar form and color. The honey-bee has its enemies; the toads and tree-frogs feed upon it, and the kingbird captures the slow drone.
Right across the river was an immense corn-field. The green corn was waving with every little breeze that passed; the tassels were bowing and nodding their heads; the pollen was flying across the river like little snowdrops, and everything seemed to say, "Come hither, Johnny Reb; come hither, Johnny; come hither." The river was wide, but we were hungry. The roastingears looked tempting.
When the crimson threads appear in the scaly buds the staminate catkins are lengthening, and soon the high wind shakes the golden pollen over all the copse. These flowers which appear before the leaves all depend upon the wind for their fertilization. That is why they come before the leaves. And there is always wind enough to meet all their needs. March is a masculine month.
He returns with his booty and wishes to disburse himself in the nest, finds the cellule which he has to fill, and proceeds always in the same order: first, he plunges his head in the cell and disgorges the honey which fills his crop; secondly, he emerges from the cell, turns round, and lets fall the pollen which remains attached to his legs.
If the reed, without being of inordinate width from the point of view of the cocoon, is nevertheless too spacious to afford the Bee a suitable purchase against the wall at the moment when she is disgorging honey and brushing off her load of pollen; the Osmia altogether changes the order of her work; she sets up the partition first and then does the victualling.
