540 IMPROVED BLINDS AND CASTRATION HOPPLES. 
sizes: a stout piece of leather is sewn to it, which ends in a buckle 
and receives the strap coming from the collar. This strap and 
buckle serves a very important purpose ; it keeps the collar ex- 
actly in its place, and prevents that annoying accident not uncom- 
mon in operations, by means of the common cart-rope, with colts, 
namely, the rope collar, in the struggles of the animal, being forced 
completely out of its place or over the head ; and another most 
essential use of this girth strap is, that, the collar being made a fix- 
ture, you have a firm pulling point from the withers instead of the 
shoulders, the leverage being so much greater, and the legs being 
brought so much more out of the way for operation. There are 
many, other matters not directly connected with these hopples in 
particular which need not be entered into, such as the particular 
nooses and hitches for securing animals when down without inter- 
fering with the facility of instantly releasing them. A knowledge 
of these things is highly valuable, although the information is fre- 
quently neglected to be sought after, from being mechanical. 
In the use of these hopples the halter and the blinds (with the 
covering for the eyes thrown backwards) may be applied ; the 
collar and the belly girth put on and adjusted. If the animal is 
wild, he may be allowed to stand with these things on, or, by the 
assistance of the rope with the spring catch attached, he may be 
lunged and pulled about, and made somewhat sullen or tractable ; 
and, lastly, when all is ready, the blinds may be instantly pushed 
forward, the rings secured to the collar, and the animal thrown 
down.
