Several formulas have been given for making the wash but 

 there seems to be little difference in the results. One good 

 formula is : — 



Lime, 20 pounds. 



Sulphur, 18 pounds. 



Water, 48 gallons. 



As spraying is usually done with barrel pumps holding 

 about 50 gallons, this formula is prepared to fill such a 

 barrel. 



The lime used should be the best stone lime, freshly 

 burned, and as little slaked by standing as possible. Fin- 

 ishing lime gives excellent results. 



The sulphur should be either flowers of sulphur or sulphur 

 flour; stick sulphur will not do. These materials should be 

 prepared in an iron kettle holding at least 30 or 40 gallons, 

 as follows : Place 6 or 8 gallons of water in the kettle, start 

 a fire under it, and slake the lime, getting this as fine as 

 possible in the slaking. When this is well under way grad- 

 ually add the sulphur, stirring it in well, and keep the fire 

 going to continue the heat begun by the slaking lime. Boil 

 the mixture, adding water as may be needed from time to 

 time, till the color of the liquid becomes dark orange-red. 

 This should take from forty minutes to an hour, the longer 

 boiling seeming to bring more of the sulphur into solution 

 and leaving less sediment at the bottom of the kettle. When 

 the boiling is completed strain the liquid into the spray 

 pump barrel, using a strainer of copper wire of at least 20 

 threads to the inch, and add any water necessary to make 

 the 48 gallons, and spray. The cooking is sometimes done 

 in barrels by the use of steam led into them, but for some 

 reason this often fails to give as good results as the use of a 

 fire. 



If for any reason this home-made wash cannot be made 

 use of, numerous ready-made lime-sulphur washes are on the 

 market, and can be used with quite satisfactory results. 



A concentrated home-made lime-sulphur wash is now being 

 used to quite an extent. The method of making, keeping 

 and diluting this for application can hardly be given within 

 the limits of this paper.
