If the length of the rein suits, it may be so held in long rides when the horse is going quietly at an extended walk, for directly as the slowness of the pace is the length of the horse, and so should be the length of the rein. The horse is at his greatest length when standing still, and if you force him to collect himself then, he will be uneasy and fidget.[16-*] But the reins must never be loose. The bearing on the mouth, however lightly, must still be felt; and if the horse, in attempting to stare about, as colts and ill-ridden horses will, should throw his head to the right, it must be stopped by the feeling of the tip of the fourth finger on the left rein; if he throws his head to the left, by the feeling of the first finger on the right rein. But provided that the bearing on the horse’s mouth, and this power of keeping his head straight, are preserved, a horse cannot have too much liberty under the circumstances supposed. To turn to the right both reins must be pulled, the right the strongest, by feeling the tip of the first finger towards you; both legs must be pressed, the left the strongest; the whip shown on the left. To turn to the left the reverse indications.
Down clutch. To take up the reins use the downward clutch[16-†] ([Fig. 4]); that is, place the two first fingers of the right hand between the reins at the greatest convenient distance, and slide them smoothly back. Repeat this movement, changing from hand to hand, and keeping the chair balanced and steady. This clutch is excellent for a straight-forward, hot horse; it shortens the reins any length at one movement, with a very low, steady bearing. Two hands may be used ([Fig. 5]). Grecian mode. I conceive this to be the Grecian mode of holding and handling the reins (see [frontispiece] and [vignette], from the Elgin Marbles), except that the Greeks had one finger between the reins instead of two; and they held the reins, whether together or divided, between the thumb and the second finger. The first finger was thus detached, and used only for guiding, by which very distinct indications may be given on either rein when both are in one hand.
