There is, at this time, a great variety of pumps, nozzles and

much in use and very good for general purposes. The cart is 
very convenient in movirg about among trees and in places 
where a wagon would be troublesome. When it is desirable, 
the barrel may be removed from the cart and placed in a wagon 
together with several spare barrels filled with the prepared in- 
secticide. This may be driven to the infested place and the 
spraying can be done from the wagon. A very handy form of 
pump for gardens, lawns, small orchards, and green-houses is 
that shown in Fig. 71. In tinis case the liquid is carried in a 
pail while the pump is held in position by placing the foot ona 
rest outside.’ Fig. 72 shows such a pump in operation. An-
