PLATE VII 



SMALL HAND SPRAYERS 



Fig. 1. — A small-capacity spraying machine of the fog or mist class. 

 Hand-driven sprayers have a very limited field of usefulness in shade tree 

 spraying operations. 



Fig. 2. — One of four machines used by the City of Cleveland in shade tree 

 spraying work 15 years ago. It would require about a hundred of these to 

 cover the ground which her one modern solid-stream sprayer now covers and 

 the work would not be done as well.
