meadows containing large quantities of arrow-grass. A sheep owner 

 reported the death of lambs when they fed late in the spring on 

 meadows where arrow-grass was abundant. From the statement it 

 appeared probable that death was due to this plant. 



There seems some reason to believe that the plant might cause death 

 in animals which had been on dry feed so long that they would fill up 

 on almost anything green. There appears to be greater danger when 

 the plant is fed dry in hay ; the dose required to kill is then far smaller, 

 and there is greater probability that a fatal quantity will be eaten. 



Cure of Animals Poisoned with Arrow-Grass. 



No experiments were made to determine whether it would be possible 

 to cure a poisoned animal. Apparently there is little hope or prospect 

 of success, because a dose large enough to cause illness is likely to cause 

 death, and because the interval between the time when the first symp- 

 toms appear and the fatal result is too short to permit of treatment. 



Prevention of Poisoning. 



With arrow-grass as with other poisonous plants it appears that not 

 much can be hoped for in the cure of animals already poisoned, but 

 that a good deal can be done to prevent poisoning. Wet meadows, 

 where arrow-grass is very common, should not be cut for hay. How- 

 ever, where the plant is distributed in small clumps rather uniformly 

 and is not very abundant there is little danger. The largest clumps 

 should not be cut, or, if cut, should not be loaded on the wagons 

 and should be burned when dry.' Animals should not be put on pas- 

 tures containing an abundance of arrow-grass when they are very 

 hungry. In some cases, moreover, portions of pastures and meadows 

 where arrow-grass grows in great abundance should be fenced and left 

 unused. By these methods it should be easy to prevent losses due to 

 this poisonous plant.
