SOLID STREAM SPRAYERS IN ACTION 



Fig. 1. — The solid-stream sprayer in use on street trees. The spray is 

 much more easily directed by the solid stream method than by the mist method 

 and at the same time the operators are better able a protect the nearby dwell- 

 ings from the drift of the finely divided liquid.
