DESCRIPTION OF PLATE XXX. 



Views of the right and left sides of the Gunnis power sprayer of San Diego, Cal. 

 This sprayer is one of the Hghtest, most compact, and most practical power sprayers 

 in use for general orchard work. It supplies 2 or 4 lines of hose, as may be desired. 

 A tender is commonly used to carry the spraying materials to the orchard, where an 

 extra rotary pump, worked by the same power as tlie spray pump, rapidly transfers 

 the spray to tlie tank of the spray wagon. Such an outfit is adajjted to extensive 

 orchard work. Mr. II. R. Gunnis, San Diego, Cal., is the owner and operator of this 

 machine.
