Suppling the Forehand. The hind quarters having been 

 drilled by the foregoing work, we must promptly train the 

 forehand in order that both ends of the horse shall be in 

 harmony as regards mobility and suppleness. 



Shoulder In. "Shoulder in" is the starting point in fore- 

 hand suppling; this exercise furnishes the means of bending 

 the forehand and spinal column and of training the fore legs 

 to cross each other easily. La Gueriniere says: "This les- 

 son produces so many good results at once, that I consider 

 it the first and the last to be given to the horse". 



"Shoulder in" is obtained in the following manner: 



Marching on the right hand, open the right rein as in 

 changing direction to the right, and press the left rein upon 

 the neck. Close the right leg to push the mass from right 

 to left and slip the left leg behind the girth to restrict as 

 much as possible the swinging of the haunches. 



The support of the left rein is indispensable in order to 

 keep the proper balance of the shoulders, that is to prevent 

 the weight of the right shoulder from plunging heavily upon 

 the left shoulder. 



The horse's head must be firmly held between the two 

 reins, otherwise the exercise would become a lateral flexion 

 of the neck and would do more harm than good. 



The bending of the horse's body should not be ovei- 

 strained. For example it is perfect if, on the right hand, 

 the left front foot and the right hind foot make tracks on a 

 line obviously parallel to the wall of the riding hall. 



The dift'erence between shoulder in and two track work 

 is analogous to that between haunches in and two track 

 work. In the movement of shoulder in, if the trooper eases 

 the hands slightly, the horse, being bent and not obliqued, 

 will quit the trac^k and start to make a circle. If, in
