CH. XIV DRIVING APPARATUS 347 



Above five pounds represents a lugging team, 

 and with eight pounds, or, in all, thirty-two pounds, 

 a man's arm would soon give out. 



Since seventy pounds is a fair tractive force for 

 a coach, on a good road, it often happens with a 

 pulling team, that a large part of the traction is 

 throuoh the reins and the coachman's arms ; in 

 speaking of the strength required to hold a team, 

 it must be remembered that no man on the box can 

 exert more strength than the amount required to 

 draw the coach, for as soon as that is reached, the 

 horses draw wholly by their mouths instead of by 

 their shoulders, and the coachman's arms merely 

 take the place of traces. 



In using the apparatus, the conical weight should 

 be put on top, to prevent the weights from catching 

 on each other as they move up and down. 



In discussing methods of fingering, this apparatus 

 is convenient, since all the movements of the hand 

 and fingers can be made, exactly as they are made 

 on the coach-box. Any new fingering can be, by 

 practice, easily acquired, and when one has not 

 been driving for a time, the fingers and arm can be 

 brought into condition by a little daily work with 

 heavy weights. 



The space between the lower roller and the 

 smooth round pin which connects the sides of the 

 frame, permits the addition of a third rein in case 

 practice in six-horse driving is desired. 



Several interesting little matters, such as the
