Rep. 13, 1899-1900.) Horizontal pumps are also used for very extensive work in spraying. These pumps are in general more powerful than the ordinary barrel pump and can accomplish more work. They are usually of sufficient strength to operate several lines of hose. Various accessories are not only desirable but almost neces- sary to the successful use of spraying apparatus. A number of such accessories together with different kinds of nozzles are given in the accompanying fig- ures. Special spraying apparatus has been devised for various pur- poses. Asparagus spraying has been carried out successfully against rust by a very complicated machine which will spray several rows of asparagus at one time. (See N. Y. Ag. Ex. Sta. Bulletin 188.) In barrel and all smaller pumps the power is hand power, in the larger machines wheel gears and chains transform the power from the wagon motion, while in still other cases, espe-.
