A good pump should work easily, maintain a 

 steady spray from one or several nozzles, be simple 

 in construction, have non-corrosive brass working 

 parts, be durable 

 and able to stand 

 hard use, be 

 easily taken to 

 pieces for re- 

 pair, have pipes 

 properly arranged 

 to prevent clog- 

 ging, and be pro- 

 vided with an 

 agitator which 

 keeps the solu- 

 tion in vigorous 

 motion and thoroughly distributed. Judging a pump 

 by cheapness alone is likely to be poor economy. 



Nozzles : The Vermorel nozzle is very popular ; 

 so are several other makes that I have tried. The 

 main thing to demand is a nozzle that will throw a 

 fine mist, like steam, which settles on the plants like 

 dew. A sprinkler, resulting in much "drip" upon 

 the ground, is not wanted. And, too, a good nozzle 

 should not clog easily, and when it does clog it 

 should be quickly cleanable. (Note: All spraying 

 mixtures should be strained before using, to pre- 

 vent clogging the nozzles. A box, with the bottom 

 and top knocked out, will make a frame for a 

 strainer ; a brass-wire mesh — eighteen or twenty 

 meshes to the inch — can be securely tacked around 

 the bottom to complete the job.)
