Best prepared in quantities of 24 lbs. at a time to get sufficient heat. 

 Place 24 lbs. lime in a half barrel, add enough cold water to start it 

 slaking well and to keep the sulphur off the bottom. Dust the 24 lbs. 

 sulphur over the lime, having first worked the sulphur through a screen 

 to break lumps, then add whatever further amount of water is necessary 

 to complete the slaking. Stir well with a hoe to prevent the lime 

 caking on the bottom. As soon as the slaking is over, add enough 

 cold water to cool the whole mass and prevent further combination. 

 Strain into spray tank. Keep well agitated while spraying.
