TREE-FOG Drives Vicious Pests 

 From Shade Trees 



THOUSANDS of American shade 

 tree owners credit their beautiful 

 sturdy trees to the thoroughness of 

 TREE-FOG, the super-spray produc- 

 ed by Hayes High Pressure Sprayers. 

 These results are due to the vapory 

 texture of the spray which drives out 

 all the microscopical pests and dis- 

 eases usually missed by coarse, heavy 

 sprays. Shade tree spraying is a 

 necessity. The vigor and beauty of 

 shade trees is menaced by vermin and 

 disease. 



TREE-FOG 

 SPRAYERS 



for Thorough Shade Tree Spraying 



turn any solution into spray of vapory 

 fineness. Tree-Fog penetrates into every 

 nook and cranny every crack and crevice, 

 like a fog. Pests and disease which lurk in 

 microscropical places are routed out.

 pressure guaranteed to maintain 300 lbs. pressure 

 at full rated capacities. We make special nozzles
