During the summer and fall of 1895 severe losses among sheep 
were reported from Middle Park on account of this plant. It 
can not be considered as a truly poisonous plant for as far as we 
know it contains no active poisonous principle. When eaten in 
large quantities, however, it forms an indigestible rubbery mass, 
which obstructs the bowels. 
POISONING BY ARKAIyl. 
Because of lack of salt or great thirst, concentrated alkali 
water is often drank in large quantities, and with fatal results, 
especially by cattle. The symptoms are bloat, frothing at the mouth, 
and scours. Animals poisoned from either weeds or alkali are 
commonly found adjacent to water holes. This fact combined 
with the similarity of symptoms, makes it difficult or wellnigh 
impossible for the ordinary observer to determine the cause with 
certainty. Prevention would consist in salting the stock regularly, 
and being careful when they are first turned on the range to see 
that they do not have access to alkali water holes until they have 
become accustomed to the dilute form of the salts. Treatment 
would consist in tapping them through the left side with trocar 
or knife in case they become excessively bloated. Opium, oak 
bark, tannin, and aromatic sulphuric acid are indicated.
