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, while 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.

The rotation must be executed calmly and step by step. It is completed when the horse has about-
