bottle. Before using the Bordeaux mixture add a few drops of this 

 substance, and if a brown color is produced add more lime until no 

 reaction takes place, when the solution will be safe to use upon any 

 kind of foliage. 



If much of this mixture is to be used, five or ten times the quantity 

 of each substance may be prepared and kept in separate vessels, the 

 proper quantity being taken out when needed. 



AMMONIACAL CAKBONATE OF COPPEU. 



Copper Carbonate, 3 ounces, 



Ammonia, enough to dissolve the Copper, 



Water, 40 gallons. 



Directions for Making. 



Dissolve the copper carbonate in the ammonia, using onl}' enough 

 to dissolve all of the powder, and dilute with water to 25 gallons 

 before using. (The ammonia found at drug stores, and at other 

 places, varies so much in strength that the exact quantity cannot be 

 given.) Laiger quantities of the copper carbonate may be dissolved 

 at a time if desired, but it must be kept in glass-stoppered bottles 

 until needed. Copper carbonate is rather expensive, but may be 

 made by taking 



Copper Sulphate, 2 lbs. 



Soda Carbonate (Sal-Soda), 2\ lbs. 



Dissolve separately and pour together. Stir thoroughly and the 

 copper will be precipitated in the form of carbonate, while the soda 

 will remain in solution. Pour off the water and dry the precipitate 

 and use the quantity required as above directed. In this form, not 

 counting the labor, the cost of the copper carbonate will be only 

 about one-third that of the commercial article. 



COPPER SULPHATE SOLUTION. 



1 pound Copper Sulphate, 



25 gallons of water. 

 Dissolve at any time before using, and apply to all kinds of fruit 

 trees and plants before the buds unfold, to destroy the winter spores 

 of injurious fungi.
