. Destructive insects. Insect pests. Fi2 The Imperial nozzle (Fig. 57) is greatly used on the Sacramento River. As before stated, it is one of the plain kind, and can furnish a fine and a coarse Fig. 58. Green's End and Side Spray (Fig. 58) is a very solid piece of mechan- ism. It resembles the Bean nozzle very much, but has two distinct outlets, and also a separate circular cleaning hole. It is very hard to recommend any nozzle in preference to another; they each have good points, and fruit growers should choose according to the materials and the class of the trees they intend sprayin

EXTENSION RODS. Bamboo Extension. Fig. 59, After trees attain a certain height it is very difficult to reach every point of the tree without the aid of an extension rod. These rods vary in length from five to twelve feet. The material used is -j, |, and ^-inch gas pipe, which makes a strong and light rod. At the base of these rods is a stopcock, which is used to turn on and shut off the spray when necessary to clean the nozzle. The bamboo has been utilized for rods.
