(alternate) left posterior line, the longitudinal thrust 

 is suppressed, and, if the horse be kept steady, the 

 lateral effect only has place. This would pass the 

 left fore-foot in the neck connection across the body 

 to the left, following the reduction of the old poste- 

 rior cross-line end in the neck. Were the left fore- 

 leg, in its body connection — i. e., on the anterior 

 concave — the primary section of the forming r^ht 

 anterior line would move it in the same direction. 



§ 205. The cavesson having its action on the nasal 

 bone, of course moves the ujyper jaw downward, 

 and with a rein to each side from the projectiag 

 ring, the head joint may be influenced by closing it 

 in front on either side, or using both reins on both 

 sides at once. This closiug of the joint in front is 

 normally the result of the action of the posterior 

 winding lines, and we should thus have an "aid" 

 which would directly ^ act in favoring these Hues 

 as the bit does in favoring the anterior lines. 



Possibly the rider, with a left cavesson and a 

 left snaffle rein, and a right cavesson and right 

 snaffle rein, crossed in either hand, might find the 

 cavesson an additional aid in suppling his horse. 



* The lower jaw movement for the posterior lines is one of closing— 

 i. e., the inner bearing— for the anterior lines of opening— i. e., the outer 

 bearing. Now, as the bit only opens the mouth, the posterior lines can 

 only be favored one at a time with the bit, by the indirect action of 

 causing one side of the jaw to close by opening the other.
