antidote. The dose for a cow should be at least a pint mixed with 

 an equal quantity of water. 



In cyanide plants and gold mines, using the cyanide process, it 

 is customary to keep on hand prussic-acid antidote outfits for human 

 use, consisting of two reagent bottles and a drinking glass. Any 

 stock owner can prepare at small expense a similar outfit for use on 

 farm animals. 



Directions for Preparing Johnson-Grass Antidote Outfit: 



Bottle No. 1. Select a strong bottle of at least a quart capacity, 

 having a long neck suitable for use in drenching cattle. Place in 

 this bottle one pint of water and one ounce of sodium carbonate. 

 (Ordinary washing soda will do.) Keep tightly corked. 



Bottle No. 2. This should contain one-half ounce of iron sulphate 

 (copperas) dissolved in a pint of water. Keep tightly corked. 



Directions for Use of the Antidote Outfit. When needed, pour the 

 contents of Bottle No. 2 into Bottle No. 1, shake and administer 

 immediately. A cow should receive the entire quart of mixture. For 

 a sheep one-half pint of the mixture would be sufficient. This anti- 

 dote would be valuable also for cases of Paris green or other arsenical 

 poisoning. In case it seems desirable to have enough antidote on 

 hand for several head of cattle, larger amounts of the solutions may 

 be stored in demijohns or large glass carboys, but not in metal con- 

 tainers. When needed, empty both reagents into a pail and admin- 

 ister to each animal from the mixture. 



Attempts to administer the drenches should be cautious to avoid 

 choking, as the animal may be unable to swallow. The antidote may 

 be given to cattle and sheep through a canula inserted into the 

 paunch through the left side in the manner used for relieving bloat. 



Glucose, corn syrup, and molasses are said to be beneficial to 

 cattle in case of prussic-acid poisoning and may be given in large 

 quantities. Their administration, however, should not take prefer- 

 ence over the antidotes previously mentioned.
