der in opposition to the haunches and throws them to the 

 left. The right leg aids to push the haunches to the left. 



(c) The right bearing rein leans the head to the left 

 and puts the weight of the neck on the left shoulder with- 

 out opposing the haunches. The two legs act equally to 

 maintain the forward movement. 



(d) The right bearing rein of opposition (in front of 

 the withers) bends the neck in to the right, carries its 

 weight on to the left shoulder and throws the haunches to 

 the right by opposing the shoulders to them. The left leg 

 acts to aid in the movement of the haunches to the right. 



(e) The right bearing rein of opposition (in rear of 

 the withers) has the effect of bending the neck in and to 

 the right, carrying its weight on to the left shoulder and 

 haunch and forcing the whole mass forward and to the 

 left when the horse is in motion by the opposition of the 

 head and neck to the shoulders and haunches. The right 

 leg in pushing the haunches toward the left strengthens 

 action. 



It must be understood that in prescribing the action 

 of one leg the other is not meant to remain inactive; on 

 the contrary, it plays its part in the impulsion and as a 

 regulating aid as was said above in speaking of the agree- 

 ment of the legs. 



LATERAL AND DIAGONAL AIDS— LATERAL AND 

 DIAGONAL EFFECTS 



In instruction, to shorten explanations, the aids are 

 considered, first, from the viewpoint of the various com- 

 binations which may result from the association of the two 

 hands and the two legs; second, from the viewpoint of the 

 direction of their action, that of the effects produced. 



When the determining aids are placed on the same side 

 of the horse, right leg and right rein, they are called lateral 

 aids. 



When they are, on the contrary, one on the right, the 

 other on the left of the horse, for example, left leg, right 

 hand, they are diagonal aids. 



Taking the viewpoint of the direction in which the 

 reins act, the lateral effect includes all action of the hand — 

 for instance, the right — on the right part of the horse, 

 direct rein, opening rein; direct rein of opposition.
