POWER SPRAYING MACHINES. 



Stemn sproycrs. — It is likely that in the uear fnlure some form 

 of power sprayinj; machines will be in common use on our large 

 fruit farms. It is only about two years ago that steam was first 

 used in spraying, so tbere has not been sufficient time to fully 

 develop this form of spraying machinery. However, several firms 

 are now manufacturing steam spra;\ing outfits, and it is probable 

 that great improvements will soon be made. 



The Rochester Machine Tool Works, Rochester, N. Y., manu- 

 facture the power spraying machine illustrated in Figure 10. 

 The outfit consists of a one-horse-power engine and boiler, a 

 small steam pump and a spray tank. The entire outfit weighs 

 about six hundred pounds, and may be loaded on an ordinary 

 wagon. 



The boiler burns kerosene, and will consume about three and 

 one-half gallons in ten hours if run at full capacity. The pump 

 is powerful, but since no air chamber is provided the spray is 

 not as steady as could be desired. 



The manufacturers appreciate the necessity of agitating the 

 spraying mixture, and the engine is furnished for the purpose 

 alone. It is to be hoped that some cheaper method of agitating 

 may be devised. The manner of attaching the suction pipe to the 

 bottom of the tank should be changed. No matter how perfect 

 the agitation may be the particles of the mixture will settle in a 

 pipe attached in this manner. Aside from the annoyance of clog- 

 ging the nozzles, it not infrequently happens that the suction 

 pipe becomes entirely stopped up. This cannot happen if the 

 pipe enters the barrel 'from the top. 



The list price of this outfit complete is |250. 



Horse-poicer sprayers. — In spraying large areas of potatoes or 

 truck crops where the machine may be kept in continuous mo- 

 tion, horse-pov.er siprayers may be used to advantage. These 

 machines may be divided into two classes, those that are pro- 

 vided with a pump, and those that discharge the liquid by force 

 of gravity; of the two styles the former is much to be preferred.
