THIRTEENTH ANNUAL MEETING. Sy 



a satisfactory mixture without boiling. The quantities used are 

 as follows : 



Lime 40 pounds. 



Sulphur 20 pounds. 



Caustic soda 5 to 10 pounds. 



Water 60 gallons. 



The lime is slaked, and the sulphur added in the form of a 

 paste while the lime is slaking. These are thoroughly mixed 

 and the caustic added. Hot water is used for slaking the lime 

 and for dissolving the caustic soda. The heat makes the caustic 

 very active in dissolving the sulphur. Slaking lime is probably 

 hotter than boiling w^ater and a larger quantity of lime is used, 

 doubtless for the purpose of generating heat. This is also a 

 promising mixture, but the methods of preparation should be 

 further developed before it can be easily used in the large 

 orchard. 



Mr. Brozun's Method. 



Some of you have heard of the mixture used by Mr. A. N. 

 Brown of Delaware, prepared by putting 40 pounds of lime 

 into a barrel with 20 pounds of sulphur and adding 12 gallons 

 of boiling water. The barrel is then covered with blankets to 

 keep in the heat, and the mixture is allowed to cook for 

 twenty minutes, with only enough stirring to prevent the lime 

 from "burning" while slaking. The mixture is then diluted 

 and applied. Mr. Brown seems to think that the sulphur is 

 entirely dissolved in this process, but it does not seem possible ; 

 and perhaps it may not be necessary to dissolve the whole 

 quantity. If a portion is dissolved, the mixture may be quite 

 effective. 



One difficulty with both of the two mixtures last mentioned 

 is that hot water is required in their preparation. If we are 

 obliged to use kettles or a boiler to heat the water, we might 

 almost as w^ell boil the spray mixture, for then we can use much 

 less lime and do away entirely wdth the caustic soda, thus cut- 

 ting down the cost of the raw materials. 



Caustic Soda Solution.

 in the last nimiber of the Farm Journal. A man in California
