How to Apply the Spray.—The spray should be applied from four sides of each tree as it is impossible to cover all parts of the tree from two points. In orchard work, drive to the interval between four trees and spray one fourth of each, proceed to the next in- terval and repeat the operation and so on. Then, by coming back on the next row, the other side of one row is sprayed and each tree has been sprayed from four sides. The first two sprayings before the trees bloom are principally against the diseases, and for them a nozzle should be used which will throw the finest possible spray and evenly cover the foliage with a thin film. The finer the spray, the less jnixture is used and the better the foliage is coated. The spraying just af- ter the petals fall is the principle one against the apple worm and must be directed from above the fruit with considerable force, so that the spray will be driven into the open calyxes. A nozzle giving a strong spray, leaving the nozzle in a good stream and making a spray with more force, is therefore desirable. Nozzles attached to the extension rod so as to form an angle of 30 or 40 degrees to the rod, will be found serviceable for this spraying. For the last two sprayings, a fine mist, as for the first two, is desirable. Do not try to spray against a strong wind. Spray from the windward. Fig. 35.—" The day of the sky-scraper tree is ;.
