Instead of a bamboo pole with the hose attached, some farmers use a gas-pipe of proper diameter, to the end of which the nozzle is screwed. This is somewhat lighter, and the slender pipe is more easily managed. But all these are details which the agriculturist can arrange for himself A surprising amount of spray can be ob- tained from a nozzle of this kind with a very small actual expen- diture of liquid ; but where a great deal of spraying is done, two or three nozzles grouped at the end of a larger discharge pipe are sometimes used.
