To the true lover of horticulture there is a fascination in the work of systematic hand-pollination of a flower. As Lindley said many years ago: "What increases the charm of the game is that although the end of it may be doubtful, yet a good player can judge of the issue with tolerable confidence, and that skill and judgment have in this case all their customary value."

Up to the present time the great advance in this line has been with the roses and border flowers. The production of the orchard fruits by crossing is a slower process, but the outcome is quite as certain. As an example, the writer a few years ago crossed some flowers of the De Soto plum with pollen of a Japanese variety. Through an accident only four plants were saved. All of them bear fruit better in quality than any of our natives and one of them is as large as the Lombard and superior to it in quality.
