FORMULAS. 



LIME, SULPHUR AND SALT. 



Unslaked lime 40 pounds. 



Sulphur 20 pounds. 



Salt i 15 pounds. 



Water 60 gallons. ' 



Place 10 pounds of lime and 20 pounds of sulphur in a boiler 

 with 20 gallons of water, and boil over a brisk fire for not less 

 than one hour and a half, or until the sulphur is thoroughly 

 dissolved. When this takes place, the mixture will be of an 

 amber color. Next place in a cask 30 pounds of unslaked lime, 

 pouring over it enough hot water to thoroughly slake it; and 

 while it is boiling, add the 15 pounds of salt. When this is 

 dissolved, add to the lime and sulphur in the boiler, and cook 

 for half an hour longer, when the necessary amount of water 

 to make the 60 gallons should be added. 



A much easier method of preparing the above wash is as 

 follows: Make the sulphur into a thin paste with hot water; 

 place the unslaked lime in a tight barrel and add the sulphur 

 paste and from 10 to 15 gallons of boiling water. Cover the 

 barrel with sacks and a wooden cover and let it stand. After 

 the violent boiling has subsided, the mixture must be stirred 

 thoroughly until all indications of boiling stop. Then add the 

 salt and enough hot water to be able to strain the mixture into 

 the spray tanks, and add the required quantity of boiling 



water.
