heated up or excited. The first thing to do is to 

 become familiar with the plants and with the 

 symptoms of the disease, keeping the live stock 

 away from it. When a locoed animal is found 

 it should be immediately taken up, given a good 

 physic, and then plenty of grain. Sheep and 

 cattle, if not too badly locoed, will make a fairly 

 good recovery, put on flesh, and may be sold for 

 the block. It seems useless to try to exterminate 

 loco weeds from the range. The symptoms of 

 the disease are lack of thrift, temporary blind- 

 ness and crazy staggers. 



LARKSPUR In amount of damage done to livestock in- 



terests of the West larkspur is second in import- 

 ance only to loco. It is widely spread and in 

 many places the only serious poison weed. 

 There are several different species of larkspur. 

 These are commonly known as the tall and the 

 dwarf larkspur. It appears that they are all 

 poisonous and they may all be recognized when 

 in bloom from the characteristic color (blue) 

 and shape of the flower. Larkspur does its dam- 

 age to live stock in the early spring, and almost 

 invariably just after a rain or a snow storm. 



SYMPTOMS OP The animal is seen to stiffen its legs and will 



POISONING stroll along for a while and finally fall ; and it 



will be found to be bloated much the same as 



from eating alfalfa. The animal slobbers at the 



mouth and swallows continually.
