THE DIAGONAL EFFECT 



cept that he holds in his right hand the right reins 

 of both curb and snaffle and also the whip. By 

 means of these two reins he secures a partial flexion 

 to the right; and at the same time, by means of the 

 curb rein held in his left hand, he maintains the 

 head, mouth, and neck inclined to the right. Then, 

 with the whip, he makes the animal execute the 

 mobilization of the hind quarters from left to right, 

 step by step. After some practice at these rotations, 

 both from right to left and left to right, the trainer 

 mounts and repeats the mobilizations by the same 

 effects, but using his leg instead of the whip. But 

 an experienced trainer begins these rotations by 

 diagonal effect, mounted. 



For the rotation from left to right, by the right 

 diagonal effect, the cavalier mounted, the horse 

 standing still and in equilibrium, both reins of the 

 bit and the left rein of the snaffle are taken in the 

 left hand, and the right rein of the snaffle is taken 

 in the right hand. The left hand keeps the horse's 

 head perpendicular, the "in hand" position, wnile 

 the right hand, by a light opposition on the right 

 snaffle rein, inclines the horse's head to the right. 

 Meanwhile, the effect of the rider's right leg impels 

 the horse forward, and the left leg, increasing its 

 effect, pushes the haunches toward the right, the 

 animal's right fore leg gaining a little ground to the 

 front. (Figures 21, 22.) 



The rotation must be executed calmly and step 

 by step. It is completed when the horse has about-
