Do not use anything to mix the poison in or to 

 keep the poisoned grain in that will ever be used 

 for any other purpose. Buy a two-gallon glazed 

 crock to mix the poison in and after the liquid 

 has been stirred into the wheat use a hammer on 

 the crock and bury the pieces. Use an iron tub 

 to mix the grain in and then keep the tub for that 

 purpose. 



This receipt, using one bushel of wheat, will 

 make enough poison to destroy a prairie-dog- 

 town of twenty-five hundred holes. 



Take 1 bushel wheat, 



3 ounces strychnine, 



8 ounces cyanide of potassium, 



1 teaspoonful oil anise, 



2 quarts molasses, 



4 quarts water, 



2 quarts corn meal. 



Put the strychnine in a quart of water in a 

 tin can, and the potassium cyanide in another 

 can with a quart of water. Set on the stove and 

 let come to a boil, stirring with a stick to dissolve 

 the poison. The strychnine may not all dissolve. 

 Be careful not to breathe the fumes from the 

 cyanide. Then pour the two poisons together 

 in a larger can or the jar spoken of. Add two 

 quarts more of warm water and the molasses and 

 let come to a boil again. Stir thoroughly and 

 let cool. Then add the oil of anise and stir more. 

 Put the wheat in the tub and add the poison mix- 

 ture a little at a time and mix until every grain
