Better Working Qualities 



S-W Dry Powdered Arsenate of Lead possesses maximum 

 lightness and flufiincss. This results in maximum suspension, 

 distribution and adhesiveness. It contains from 30 to 33% 

 arsenic oxide, and less than 1' p water soluble arsenic. These 

 properties and proportions assume maximum killing, without 

 danger of injury to foliage or fruit. It works effectively on 



while it developed three good sprays, it also proved 

 that Sherwin-Williams Dry Powdered Arsenate of
