REMEDIES. 
Based on the statement that pigs fed on fresh milk are not poi- 
soned, experimental work has shown that beneficial results follow 
the administration of oils or fats. For this purpose linseed oil, bacon 
grease, or lard can be used. 
WESTERN SNEEZEWEED 
(Helenium hoopesii). 
Western sneezeweed 
{Helenium hoopesii), 
sometimes called " yel- 
lowweed " by the stock- 
men, is found in great 
abundance on the sheep 
ranges of the Wasatch 
Mountains in Utah, 
especially in localities 
where the range has 
been heavily grazed. 
The plant is distrib- 
uted in greater or less 
numbers from Wyo- 
ming in the North to 
New Mexico and Ari- 
zona in the South, and 
as far west as California, but it is in Utah that it has become promi- 
nent as a poisonous plant. 
The plant, shown in Plates XXXVI and XXXVII, is a stout 
perennial composite, growing to 2 or 3 feet in height, with thick 
deep-green leaves. The 
rays of the flower are 
of an orange color and 
the disk a brownish 
orange ; the blossom- 
ing period in the Wa- 
satch Mountains ends 
the middle or last of 
August. Its range in 
elevation is from 7,000 
to 10,500 feet. 
Under ordinary 
range conditions the 
western sneezeweed 
seems to be dangerous 
only to sheep although 
there have been some 
fairly well-authenti- 
cated losses of cattle 
from this plant. It has been found to be the cause of wind is known 
in Utah as the "spewing sickness" of sheep, from which there have 
been quite heavy losses. 
Symptoms of Poisoning r.v Western Sneezeweed.
