482 THE MONTHLY BULLETIN. 



Our formulie are given below, and as a parting word we would advise- 

 the grower to make his own crude oil emulsion by all means as it is 

 cheaper and more effective. 



Crude Oil Emulsion, Liquid Soap Formula. 



Place SS gallons of water in the spray tank and add 1 to 2 gallons, depending on 

 the softness of the water used, of liquid soap diluted with about an equal amount of 

 water. Agitate until thoroughly mixed and then with the agitator running add 10 

 gallons of crude oil. 



Whale Oil Soap Formula. 



Dissolve 10 pounds of whale oil soap in not less than 10 gallons of water by 

 boiling, slice the soap and it will dissolve more quickly. Place this in the spray 

 tank which should contain about 10 gallons of water. Thoroughly agitate and add 

 enough water to make 90 gallons, then add 2 pounds of caustic soda (concentrated 

 lye), dissolved in water. With the agitator running add 10 gallons of crude oil^ 

 slowly.
