 poisoned bran made as follows: to three ounces of 

 molasses add one gallon of water and sufficient bran 

 to make a fairly stiffened mixture. To this add Paris 

 green or arsenic and stir well into a paste. A heap- 

 ing teaspoonful of the mixture is scattered here and 

 there over the infested land.
