SPRAY PUMPS AND APPLIANCES. 



What is the best spray pump? That is a question often asked, and 

 entirely impossible to answer with any assurance of satisfaction. Some 

 growers get along very nicely with the small bucket pumps (if their 

 orchards are not large), while others quickly abandon them for the 

 larger and more powerful kinds. Some (especially gardeners and truck- 

 ers) prefer the knapsack pumps, while others say that they wouldn't 

 have one, as they are too hard to work with. Some like the compressed- 

 air sprayers that are carried about by hand (many are in use among 

 tobacco growers), while others object that they hold too little liquid and 

 that too much time is required in filling the tank every few minutes. 



There is just one invariable rule than can be laid down, and that one 

 holds good regardless of whether you are rich or poor, and that is, get a 

 good, strong, durable pump — large enough and strong enough and with 

 enough hose and extension pipe to reach every part of your trees with 

 a fine, misty spray. It is also a great advantage if the pump has an 

 agitator for keeping the liquid stirred so the ingredients will not settle 

 to the bottom. 



Barrel Pumps for Standard. -Considering everything— the cost, the 

 durability, the capacity, the labor we have, the kinds of fruit and the 

 size of our orchards, we believe that for the majority of our people who 

 have or are planting orchards for market purposes the barrel pumps are 

 best, and should be generally considered as the standard. Those with 

 orchards of 1,000 or more apple or 3,000 or more peach may profitably 

 get more elaborate outfits, while those with only about 100 apple or 200 

 peach (or less) may do all right with the smaller pumps. 



A good barrel pump, with two leads of hose, extension pipes, double 

 nozzles, stopcocks, etc., will cost, complete and ready for use, about $25 

 to $35. It is usually better to order that the pump be fitted into the 

 side of the barrel. If you get the pump alone and fit it into the barrel 

 vourself it will cost less.
