(2) Dry Lime-sulfur. 

 Drj' lime-sulfur was first marketed in 1915 by the Sherwin-Williams 

 Company of Cleveland, Ohio. The use of the dry product effects a material 

 saving in cost of containers, transportation, storage and possible leakage. 

 Commercial lime-sulfur solution contains nearly 68 per cent of water, 

 while the drj' product usually contains onh' a small amount of uncombined 

 ^\•ater. In the production of dry lime-sulfur the polysulfide apparently 

 undergoes partial decomposition, and a portion of the sulfur formerly
