CH. XIII SIX HORSES 277 



with the eye large and set horizontally, or with a 

 regular Q , so that it will go on the pole-hook ; all 

 his harness is the same as that of one of the leaders. 

 The long reins may with advantage be passed on 

 the inner side of the wheelers' bridles. 



Should one of the horses of a team of four give 

 out, thereby forcing the. team to become a spike, or 

 unicorn, the single lead-bars should be taken off and 

 the leader's traces hooked to the main-bar. 



If the hooks of the main-bar are too thick to 

 permit the cock-eyes of the lead-traces to go on 

 them, one of the single-bars must be used, attached 

 to the pole hook by a strap, since its eye is turned 

 the wrong way to go on the hook. 



Six Horses. — When six horses are put to a coach 

 in three pairs, the middle pair is called the swing- 

 pair. This designation is also used in the Artillery. 



The harness is exactly the same as for four horses. 

 The lead-reins pass through the throat-latch rings 

 and the pad-terrets of the swing horses, and then 

 through those of the wheel horses to the hand. 



The swing-reins run exactly as do the lead-reins 

 of an ordinary team, but the throat-latch rings on 

 the wheelers must be doubled to take the additional 

 reins, those from the leaders going on top, and the 

 wheel pad-terrets should have a bar across them to 

 keep the lead-reins and swing-reins apart. 



Either a pole or a chain may be used to connect 

 the lead horses to the coach.
