SPRAYING MACHINERY 



The question is often asked : \\'hat is the best spray 

 pump? Such a question cannot be answered. Even 

 when the requirements are somewhat definitely known 

 no one can truthfully say that one make of pump is 

 better than all the others. In fact, a good nozzle, con- 

 veniently rigged to a well-made cylinder makes a good 

 spray outfit. The particular pattern or maker's name 

 is of small consequence. It may be said at the outset 

 that hand pumps are most practicable for small planta- 

 tions. Anyone with less than 200 mature apple trees 

 will hardly need a power sprayer. For any undertak- 

 ing larger than 200 mature trees, however, some form 

 of power machine will prove an economy. 



Of the hand pumps there are all kinds, but they may 

 be somewhat arbitrarily divided into two general types. 

 The first would include the small single-acting pumps 

 mounted on a barrel ; the second would include larger 

 pumps, usually double-acting, and usually mounted on 

 larger tanks. The barrel pump, which is the smallest 

 and cheapest practical outfit for effective spraying, can 

 be conveniently loaded into any wagon. Preferably it 

 is placed on a low-down truck. It can even be hauled 

 about on a stone boat. If some tank larger than a bar- 

 rel is required, it is best to buy one of the ready-made 

 sort put out by leading dealers. These tanks usually 

 hold 200 gallons, and cost $18 to $20. The common 

 form is semi-cylindrical, with the flat side uppermost, 

 making a convenient place for mounting the pump.
