 The same lime-sulphur mixture is still the sovereign 

 remedy on the Pacific coast, no other material being 

 used there to any extent as a scale spray; and else- 

 where in the United States it is the best thing yet 

 found. It is effective wherever used, if directions are 

 followed, and it is safer to use than the oil remedies 

 sometimes recommended. 



AN ILLINOIS LIME-SULPHUR OUTFIT. STEAM- 

 COOKING IN ELEVATED BARRELS 



Formula for making the lime-sulphur spray: Slake 

 twenty- two pounds of fresh lump lime in the vessel in 

 which the mixture is to be boiled, using only enough 

 water to cover the lime. Add seventeen pounds of 

 sulphur (flowers or powdered), having previously 

 mixed it in a paste with water. Then boil the mixture 

 for about an hour in about ten gallons of water, using 

 an iron but not a copper vessel. Next add enough 

 more water to make, in all, fifty gallons. Strain 

 through wire sieve or netting, and apply while mixture 

 is still warm. A good high-pressure pump is essential 

 to satisfactory work. Coat every particle of the tree.
