Homemade lime-sulphur dip is made in the proportion of 12 pounds 

 of unslaked lime (or 16 pounds of commercial hydrated lime) and 24 

 pounds of flowers of sulphur to 100 gallons of water. The lime and 

 sulphur should be weighed and the water measured; do not trust to 

 guess work. Slake the lime in a shallow, water-tight box or tank and 

 add water enough to form a thin paste. Sift the sulphur into the paste 

 and mix well with a broad hoe until a mixture of about the consistence 

 of mortar is formed, adding water as required. Put the mixture into 

 30 gallons of boiling water, adding it slowly so as not to interrupt the 

 boiling, and boil until the sulphur disappears from the surface. The 

 boiling should be continued for from one and a half to two hours with- 

 out cessation, and the mixture stirred to prevent settling and caking 

 on the bottom. When the sulphur has disappeared from the surface 

 and the mixture is of a chocolate or dark-amber color, the boiling- 

 should be discontinued. 



The contents of the boiling tank should be drawn off or dipped out 

 and placed in the settling tank and allowed to stand until all solids 

 have settled to the bottom and the liquid is clear. An ordinary w T ater-

tight barrel will serve very well for a settling tank at a small vat. A 

 settling tank of any kind should have an outlet at least 4 inches from 

 the bottom in order that the clear liquid may be drawn off without 

 becoming mixed with any of the sediment. 



When the sediment has fully settled draw off the liquid into the 

 dipping vat and add warm water to make a total of 100 gallons of 

 dip. When mixed and cooked as specified above the concentrate is 

 three and one-third times the strength required for the dip in the vat, 

 so that to every 30 gallons of such concentrate 70 gallons of warm 

 water should be added to make a dip of the required strength.
