PLATE VIII 



A POWER SPRAYER OF THE MIST OR FOG CLASS 



This is one of the machines operated by the Board of Park Commissioners 

 of Cincinnati, Ohio. Sprayers of this type have a considerable field of useful- 

 ness in Ohio, particularly where shrubbery and low trees in parks require 

 annual treatment for scale. Note the sturdy construction of the running-gears, 

 an important detail when used on uneven city pavements.
