The reins having been properly placed in the left hand according to the directions just given, this hand, being closed, but not too tightly, must be held at a distance of about three inches from the front part of the waist, with the wrist slightly rounded, the nails toward the body, the back of the hand toward the horse's head, and the little finger down and a little nearer the body than the others. The under surface of the bridle arm and hand, from the tip of the elbow to the first joint of the little finger, should be held nearly in a horizontal line. The elbow must be held somewhat close to the side but not in contact with it, and should be kept steady. Care must be taken, when the reins are held in the left hand, that the right shoulder be not thrown back, nor the left one elevated, faulty positions common to beginners when not otherwise instructed. The right arm should be allowed to hang easily and steadily at the side, the whip being lightly held in it, with its point downward. When the snaffle-reins are held in the left hand as described, we may term this the "original position," of which all the others are variations.
In order that the horse may move onward, the left hand, holding the reins as just described, should be relaxed by turning the thumb downward and toward the body until the back of the hand is up and the finger-nails down; at the same time, the pupil should slightly incline her body forward, being careful not to round the shoulders,—aiding the movement by the voice, or, if necessary, by a gentle tap of the whip. The horse having started onward, the original position must be gently resumed.
In order to turn the horse to the right, the left wrist must be turned so as to bring the nails down and the knuckles up,—the thumb being toward the body,—at the same time carrying the little finger slightly to the left, and drawing the reins a little upward. This movement will effect the necessary shortening of the right rein, without allowing any looseness of the left one. The turn having been accomplished, the hand must resume the original position. It must not be forgotten, that while making this turn the face and shoulders must be turned somewhat to the right, or in the direction in which the horse is moving.
To turn to the left, the bridle-hand being in the original position, its wrist must be turned so as to carry the finger-nails up, and the knuckles down, simultaneously moving the little finger toward the right and pressing it against the left rein, both reins being drawn slightly upward. This manœuvre shortens the left rein, without relaxing the right. In this turn the movements of the horse should be aided by the rider's face and shoulders being turned a little to the left. The turn having been made, the original position must be resumed.
The horse may be stopped by simply turning the wrist so as to carry the finger-nails up, the knuckles down, and the little finger toward the body, which must be slightly inclined backward. Now, by bracing the muscles of the hand, bending the wrist and carrying the hand farther in toward the waist, at the same time advancing the body, the animal will be made to back; though, in backing a horse, it will be better to employ both hands. After having stopped, or backed the horse, to make him move onward, a course should be pursued, with both reins in the bridle-hand, similar to that described for the same purpose when a rein is held in each hand.
To change the snaffle-reins from the left to the right hand, as is sometimes necessary in order to adjust the skirt, to relieve the left hand, etc., the following course must be pursued, whether the horse be in rapid or slow motion: While the left hand must retain its position and gentle pressure of the reins upon the horse's mouth, the right must be carried to and over the left hand, its forefinger be passed between the two reins, so that the left rein will be on the left side of this finger, and the right on its right side, between the first and second fingers; both reins must now be carried to the right, across the palm, to the little finger; the hand must then be firmly closed, and the thumb be pressed against the left rein, holding it in contact with the index finger,—the left hand now gives up the reins. In this change, while the right hand is being carried over to the left, this latter must be held stationary, as any movement of it to meet the right hand may cause the animal to turn or swerve from his course, and will at the same time interfere with his gait.
To return the reins to the left hand, the following course must be pursued: While the right hand must remain steady and sustain the gait of the horse, the left must be carried to and over it, insert its little finger between the two reins, so that the left one will be on the left or outer side of this finger, and the right one on its right side, between it and the third finger; then the reins must be drawn through the left hand, and be arranged and held in this hand in the same manner as explained when describing the original position of both snaffle-reins in the bridle-hand.
These various changes must be made quickly and expertly, without altering the degree of pressure or pull upon the horse's mouth. The novice will find it greatly to her advantage to learn the management of the reins before mounting the horse, and can do so by fastening the bit-end of the reins to some stationary object, and then practicing the different changes, until she can perform all these manœuvres without looking at her hands or the reins.
When both the reins are held in the left hand, the rider has not so much command over her horse as when they are held one in each hand. For this reason, unless her steed be exceptionally well-trained and obedient, it will be better, when in a crowded thoroughfare, where quick turns have to be made, to hold a rein in each hand, and this will become absolutely necessary if the animal be hard mouthed or unruly.
