Plates VII and VIII.
The flexion of the neck to the left is executed after the same principles, but by inverse means. The man can repeat with the curb what he has previously done with the snaffle-reins; but the snaffle should always be employed first, its effect being less powerful and more direct.
When the horse submits without resistance to the preceding exercises, it will prove that the suppling of the neck has already made a great step. The rider can, henceforward, continue his work by operating with a less direct motive power, and without the animal's being impressed by the sight of him. He will place himself in the saddle, and commence by repeating with the full length of the reins, the lateral flexions, in which he has already exercised his horse.
Lateral flexions of the neck, the man on horseback.—
1. To execute the flexion to the right, the rider will take one snaffle-rein in each hand, the left scarcely feeling the bit; the right, on the contrary, giving a moderate impression at first, but which will increase in proportion to the resistance of the horse, and in a way always to govern him. The animal, soon tired of a struggle which, being prolonged, only makes the pain proceeding from the bit more acute, will understand that the only way to avoid it is to incline the head in the direction the pressure is felt. (Plate IX.)
2. As soon as the horse's head is brought round to the right, the left rein will form opposition, to prevent the nose from passing beyond the perpendicular. Great stress should be laid on the head's remaining always in this position, without which the flexion would be imperfect and the suppleness incomplete. The movement being regularly accomplished, the horse will be made to resume his natural position by a slight tension of the left rein. (Plate X.)

The flexion to the left is executed in the same way, the rider employing alternately the snaffle and curb-reins.
