appear to be blind; they will fall over one an- 

 other, run into the fences, and they may go into 

 convulsions. If they get lupinosis in a chronic 

 form, the skin turns yellow. Horses are affected 

 in the same way, more commonly with the 

 chronic form. 



There are many poisonous plants that are 

 occasionally eaten with more or less disastrous 

 effects. The branches and leaves of the wild 

 cherry, just at the time of wilting, will kill an 

 animal quickly from prussic acid poisoning. 

 The same may be said of Johnson grass. Sec-

 in a stunted condition, will often kill from the

 horse's kidneys. Mold that grows on potatoes, 

 carrots, and other vegetables in damp cellars, or 

 mouldy sugar beet tops in the field are danger- 

 ous when eaten by animals. Potatoes exposed 

 to the sun turn green and become poisonous. 

 The Rubber weed does not kill by the presence of

 The Griant grass, or horsetail, that grows in 

 sloughs and is relished by horses, is often deadly. 



The so-called skunk cabbage (Wild lobelia), 

 grows from three to six feet high in the lofty 

 ravines and has a leaf as big as the hand. It is
