 among the poisoned animals. 



The one feeding test made with the yearling calf was so conclusive 

 that it was considered unwise to sacrifice any more cattle. The small 

 amount fed, only 7 ozs., readily produced typical poisoning symptoms, 

 and its action was so characteristic and rapid that there appeared to 

 b'e no immediate need of other tests with cattle. 



The above feedings were made by uniformly mixing with alfalfa 

 the small amounts of arrow-grass tabulated. Therefore, these tests 

 show very clearly that there is considerable danger or risk of loss when 

 arrow-grass is cut and put up with hay and fed to live stock.
