THE Loco WEED—The disease commonly termed loco among 
stock men, which especially affects the horses throughout the 
West, is one generally to be dreaded. It is usually ascribed to 
the diseased animal having fed upon some one of the many large 
species of Astragalus of which different species are found in dif- 
ferent parts of our country. If eaten green the plants seem to 
have no injurious effect—at least not so noticeable—but eaten 
dry it soon proves fatal. A tea made from the Astragalus found 
in New Mexico, given in three doses of a pint each to an old but 
perfectly healthy horse, caused death in thirty eight hours, 
according to one man, whose veracity is. however, open to doubt. 
According to the same authority, an Indian mistook a bottle of 
the tea for whiskey, resulting in a rush of blood to the head and 
death in three hours. At Fort Whipple barracks, A. T., alfalfa 
hay mixed with the loco weed rendered the horses crazy and 
foolish, refusing to be led. and relief was only afforded by bleed- 
ing in the neck veins. But no evidence agreeing with the above 
yet known to have been placed on record, that is sufficient to 
convict any plant. Some have ascribed the loco disease to the 
presence of ticks in the horses ears, and their penetrating to the 
brain, but the symptoms do not seem to agree with the genuine 
“loco.” This subject is worthy of careful study and investigation, 
and any further evidence or discussions are invited. C. 2.0.
