CH. X LENGTH OF TRACE 1 93 



ment must be used as to the conditions. The leaders 

 should have their traces long enough only to keep 

 them well but of the way of the bars, and a short 

 pole with a crab the branches of which are of suffi- 

 cient length to bring the pole-chains into the proper 

 direction, will, by bringing the leaders well back, add 

 much to the appearance of a team. 



The proper length for a wheel-trace is 84 inches 

 from the tue-buckle to the centre of the roller-bolt ; 

 for a lead-trace, 76 inches from the tug-buckle to 

 the end of the cock-eye (pp. 216, 217). From the 

 tug-buckle to the front end of the trace, the length 

 is 1 5 inches, making the whole length of the wheel- 

 trace 99 inches, and of the lead-trace 91 inches.
