88 PASTURE AND RANGE. 
Wolf, Curtis and Kaupp of the North Carolina Agri- 
cultural Experiment Station, have recently published an 
extensive account of their researches on “trem- 
Symptoms bo, in a special bulletin. From the results 
of feeding experiments they traced the disease to the 
White Snakeroot. Their treatise gives a complete and 
valuable account of the symptoms as observed by them- 
selves and by others. 
Cattle exhibit listlessness, stiffness of joints and slug- 
gishness with weakness and trembling, especially when 
driven. There is constipation and a foul “garlicky” 
breath. It is noted that among a group of animals, some 
may escape harm while. others contract the disease, 
though all have eaten the plant apparently to the same 
extent. In sheep, in addition to the above symptoms, the 
following are noted: loss of appetite, gritting of the 
teeth, quick, laboured breathing, marked ataxia, frequent 
and scanty urination. The trembling is very pronounced 
and accompanied by tetanic spasms. 
In pigs the appetite is not impaired until the later - 
stages but the trembling is very violent. 
In man there is abdominal pain, vomiting, and exces- 
sive thirst; otherwise the symptoms resemble those in 
the lower animals. 
No satisfactory cure for the disease has been discover- 
ed and the chances for such a discovery are not hopeful, 
; ; as the poison produces fundamental 
ihe bus Gave changes in the internal organs. The only 
way of overcoming the disease, therefore, 
is by not allowing the animals access to the Snakeroot. 
Pasture areas infested by it should be fenced of or cleared 
of trees and broken up by the plow.
