Bordeaux Mixture. — Six pounds of sulphate of copper are 

 dissolved in 2 gallons of hot water, and 4 pounds of fresh lime 

 are slaked in water enough to make a thin lime wash. When 

 both are cooled, pour together, mixing thoroughly and dilute to 

 22 gallons. Strain before using. 



Ammoniacal Carbonate of Copper. — Three ounces of precipi- 

 tated carbonate of copper are dissolved in one quart of ammonia, 

 strength 22° Baume. Dilute with 22 orallons of water. 



Eau Celeste. — One pound of sulphate of copper, dissolved in 

 25 gallons of water. 



Modified Eau Celeste. — Two pounds sulphate of copper, 2i 

 pounds carbonate of soda and IJ pints of ammonia (22° Baume). 

 Dilute with 22 gallons of water. 



Kerosene Emulsion. — One pound common soap dissolved in 

 hot water ; 1 gallon kerosene. Stir or churn together until a 

 smooth, butter-like substance is formed. Dilute with 25 to 50

 pigment forming a thin paste or thick paint. Apply with a 

 small brush.

 cides and insecticides. Of those most in use perhaps the best 

 known are the "Field's Perfection," made by the Field Pump 

 Company, Lockport, N. Y., the Gould pump, made at Seneca 

 Falls, and the Mixon, made at Dayton, O., all of which can be 

 attached to casks and placed on a stone-boat or wagon.
