PLATE VII 



SMALL HAND SPEAYEES 



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.
