There is a large opening at one end, and a narrow one at 

 the other. The horses are directed into the wide opening, 

 and are allowed to pass in single file into the narrow 

 channel, where they are powerless to escape and head- 

 collars are at once adjusted. 



There are certain measurements of the ' crush ' which 

 are absolute, so that a detailed consideration of its 

 structure is essential. Fig. 221 shows a plan of it. The 

 arrows show the entrance into the funnel. The exit is the 

 long, narrow gangway where the horses get caught up. 

 The funnel end is only a convenient accessory into which 

 the horses are coaxed to enter, and, by means of the

Fig. 221. — Diagram of a Plan of the 'Crush.' The dotted lines across the 

 track indicate the closing of the gates, which imprison, say, 100 horses ; 

 these follow the direction of the arrows until they get in the narrow 

 gangway. At the outlet of the gangway is a two-way gate, so that the 

 horses can pass either to the right or left. The gangway is seen in 

 section in Fig. 222, and in elevation in Figs. 223 and 224. The two- 

 way gate is seen at Fig. 225. 



V-shaped buttresses seen in the plan, they are unable to 

 return. As a matter of fact, having entered, they wander 

 forward, and soon find themselves in the gangway, with its 

 two feet inside measurement. 



The above principle of a crush is the same whether it is 

 intended to hold ten or fifty horses at a time, the only 

 difference being the question of length. In a large 

 remount depot a crush suitable for 100 horses would be a 

 convenient size, and a crush to hold this number would be 

 170 feet long at its narrow part. 



Eig. 222 shows a section of the gangway of the crush, 

 which is five feet high, and two feet wide internal
