The centers of the blossoms swell and grow and color: cherries and apples, peaches and pears, figs which close the flower in the fruit. All California quickens with produce, and the fruit grows heavy, and the limbs bend gradually under the fruit so that little crutches must be placed under them to support the weight.

These men work carefully and endlessly to perfect the seed, theroots. And there are the men of chemistry who spray the trees against pests, who sulphur the grapes, who cut out disease and rots, mildews and sicknesses. Doctors of preventive medicine, men at the borders who look for fruit flies, for Japanese beetle, men who quarantine the sick trees and root them out and burn them, men of knowledge.
