There is no one best pump or nozzle. There are best devices for 

 particular kinds of work, depending on the size of plants to be 

 sprayed, the kind of spray to be used, the extent of the operations. 

 Get a good pump, one that works easily and smoothly and is strong 

 enough to make a tine spray when two lines of hose and four nozzles 

 are used, if it is designed for Held work ; it is economy in the end. 

 Look over the agricultural papers for advertisements of spraying 

 outfits and write for circulars. 



The advice given in this Bulletin is intended to be suggestive 

 merely. In so brief a space it is impossible to go into details. The
