When the trot is extended to an unpleasant roughness, the jolting may be eased by rising upward and slightly forward in the stirrups. The faster the horse trots, the easier it is to rise; for it is the action of the horse, and not any effort of the rider, that must raise him. The foot he leads with determines that which the rider must rise to; and, if the horse change his foot, he must change with him. He must accordingly rise and fall with the leading foot, rising when the leading foot is in the air, and falling when it comes to the ground. The rise and fall of the body are to be smooth, and as regular as the beats of the feet. [Illustration: _Plate XXXIX_ _Page 150._ The Trot. Road Riding.] Though this is called rising in the stirrups, no great stress or dependence is to be put on them. Such improper use of the stirrups causes many persons to be thrown, by the horse shying or suddenly turning round. The rising of the body must not be accompanied by any motion of the arms, or lifting of the shoulders. The hand is to be held steady as well as low, to prevent galloping (which the forwardness of the haunches would render inevitable if the hand were either eased or lifted), and the reins should be of that precise length which preserves as much correspondence as possible between the hand and mouth. The steadiness of the hand is also necessary for the support of the horse. The slight inclination of the body permitted in road riding must not occasion any roundness in the back, which is invariably to be hollow, not only for appearance sake but for safety. The action of the body likewise must not cause the legs to move or press the horse, which might cause him to gallop. In trotting, the rider must pay the greatest attention to correct every propensity to lift, hitch, overrate, or gallop; and, whenever he feels these propensities, he must check them with the greatest nicety, in order not to retard the horse’s speed. (Pl XXXIX. f. 2 illustrates the Seat, &c., in Road Riding.[68]) [68] In road riding, the rule of taking the right hand of all you pass is well known; but there are some exceptions, which are thus noticed by Mr. Bunbury, in his ironical style:--
