"Sometimes the pollen from one flower falls on its own pistil, sometimes the wind, the bees, the birds carry the pollen to flowers far off and drop it on their pistils. Marvelous, is it not? Everything has to be just right, or the pollen does not do its work nor the pistil, either. Pollen has to be ripe to help make the seed.
"But how can the work of the wind and the bees and the birds be improved on? Just as the old gardener was doing it. He had one pansy, oh such a large one, but not at all beautiful in colour. He had another one, small but exquisite in colouring. If he could but grow those two together, shake them up, say a magic word and get a pansy both beautiful and large!
"Rodney's gardener used magic but not a magic wand. He took a little knife called a scalpel. He carefully took some pollen from the beautiful pansy and then rubbed it gently over the pistil of the big pansy. The pollen was all ready to drop, and by this he knew it was ripe.
"Why did he place a bag over the pansy? Well, simply because he didn't wish that pansy interfered with. Suppose the bag were not on; suppose after he had put the pollen on, the wind had blown other pollen to this same pistil? Let us suppose that this other pollen came from a very inferior flower. The experiment would have been spoiled.
"Any of you can try this plant improvement. I see by Katharine's eyes and Dee's also that they are going to try it. It is well if you have a pair of forceps. Then you need not use your fingers against the plant at all. Gently pull the pistil a bit forward, gently place the pollen on with the scalpel and you have performed the operation entirely with the proper instruments.
"The girls did some saving of fine specimens of flowers this fall, but the kind of work of which I have just told you means far more. In the one case you choose from what you have; in the other case you make what you want.
"Good-by, again, until next Friday afternoon!"
