THE AMERICAN PEACH ORCHARD 



rel serves best. Any good strong barrel will do, 

 but convenient barrels are sold also by the dealers 

 in machinery. 



The pump may be either run by hand or by a gas- 

 oline engine. Other types of power have been 

 largely experimented with, such as compressed air, 

 gas, the steam engine, traction from the wagon 



wheel, etc. ; but while 

 some of these have proved 

 satisfactory in certain 

 hands, the only generally 

 successful pumps are 

 those here recommended. 

 For 20 acres of orchard 

 or more the gasoline 

 motor is to be recom- 

 mended. For less than 20 

 acres hand power is likely 

 to prove most economical. 

 Nozzles are of many 

 kinds, though for all prac- 

 tical discussion they may 

 be reduced to two types; 

 viz., the Vermorel and the Bordeaux types. The 

 general style of these is shown in the accompanying 

 illustrations, pages 148, 150, 152. Nozzles of the im- 

 proved Vermorel type are generally regarded as 

 best for careful spraying, especially for the spring 

 applications of lime-sulphur. They are also more 

 economical of the solutions used. 



The selection of proper hose presents some special 

 difficulties. The corrosive solutions soon spoil 

 almost any rubber hose, and the purchase of a new 

 supply entails constant expense. Some men prefer 

 to buy cheap cotton hose and replace it as fast as it 

 gives out. Others recommend buying the best.
