the whole body is drawn back upon them as 

 appuis. 



Under the rider, a bit which prevents the horse 

 from completing the primary section of the poste- 

 rior lines when he is urged forward, may induce 

 rearing. The lower jaw, checked in the attempt to 

 come on its inner bearings, throws back the trac- 

 tions to those which belong to the jaw on its outer 

 bearings, i. e., the anterior lines in their secondary 

 sections. If, when up, the horse thrust forward the 

 front legs on the inner bearing by introducing the 

 posterior hne in the anterior C C, we have the full 

 converse of kicking, which begins with the action 

 of both lines in the posterior C C, and ends with 

 the single action of the posterior lines in the an- 

 terior C C. 



If now, the horse rear with a perfect equality of 

 the sides, the constantly increasing action of the 

 anterior lines will finally eventuate in " setting-up" 

 by double action on these lines (§ 180), and he will 

 come down perfectly gathered. But most horses, 

 and — if they wish to resist their rider — all horses 

 rear with a preponderating action of one leg, and 

 if the rearing then be carried too far, they may 

 fall over. 



As a remedy for rearing, determined spurring.
