EXTRACTS FROM AGRICULTURAL REPORTS. 
from his portion of tiie held. The first horse died in the pasture; 
the seoond recovered from the previous feeding. In the barn he 
also placed two horses similarly affected, and fed one with dried 
loco, and the other with clean hay. The first died and the other 
recovered. 
The following summary of the effect of loco is based upon 
_ « 
personal inquiry among ranchmen. The animal unaccustomed to 
the weed will not touch it as long as good feed is to be had, but 
after once partaking of it—driven to it in early spring by the 
want of green vegetation—soon comes to prefer it to any other 
food, and finally refuses any other, leaves the herd, and wildly 
searches for loco. The first effect upon the animal is hallucina¬ 
tion. When led or ridden up to some trifling obstruction, such 
as a bar or rope lying in the road, he stops short, and if urged on 
leaps over it as if it were a rail-fence four feet high. Seemingly 
the optic nerve is affected; all sense of distance and dimension 
seems to be lost; a barn near at hand seems to him afar off, and 
one a mile away near by. He will go headlong against a barn or 
a rock, or over a precipice, as if he were totally blind. The 
animal will, perhaps, let one get close to him, then suddenly and 
wildly run away at full speed and as suddenly stop, turn around, 
and it may be, come right back, stop short, stare, “ and act like 
mad.” 
Mr. William Smith, in the employ of Bollinger & Schlupp, 
ranchmen, seventeen miles south of Kiowa ; Mr. D. R. Streeter, 
upon the “ Z & Z ” ranch, near Kiowa, and Mr. Steele, above 
referred to, are all quite familiar with the symptoms, and agree 
in every prominent particular concerning them. Mr. Steele gives 
as one of the prominent characteristics of the disease, “a stony 
stare.” “ If a sharp, quick motion is made before the animal’s 
eyes, such as throwing up of the arms suddenly, it is likely to fall 
to the ground in apparent fright, as though not able to control 
its muscles.” Sometimes a horse is seized as with a mania, in 
which he is quite uncontrollable and dangerous. He rears, even 
to falling backward, runs, or gives several successive leaps for¬ 
ward, and generally falls. His eyes are rolled upward until the 
whites can only be seen, which are strongly injected, and since he
