In some instances, when trees, shrubs, and flowers are attacked by insects, the materials for disinfection are used in a powdered state. To spread these evenly over the infested plants, various apparatus have been invented. Among the most primitive is a common preserve can with a piece of ware cloth soldered in the bottom. The fineness of the wire cloth will not permit a great quantity of material to sift through at one time, and in that way will cover the shrub with a very even coat. For high trees the can is fastened to a long pole, and by shaking the pole the sub- stance w'ill sift over the Fig. 62. The Favorite* (Fig. 62) is an improved sulphur bellows. This is no doubt the simplest and best bellows made, and is constructed in such a way that the operator can only expel just enough material without * California Bellows Co., 123,66316 Stre6t, San Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
