To carry on the lesson in the trot, the instructor should mount a cob or pony of such height as will admit of his easily placing his left hand under the right elbow of the pupil. He should ride with his reins in his right hand, and be sure that the horse he gets on is a perfectly steady one. He should now put plenty of vivacity into his own manner; he will then easily impart it to his pupil and her horse. The latter should be smartly "woke up" if at all behind his work--pressed up to the bridle with whip and leg, and "made ready" to increase his pace at any moment. The master should then caution his pupil that on the words "Prepare to trot," she should strengthen her grasp on the upper pommel, her pressure against the third crutch, and well stretch down the left heel, while she carries back the left leg, and inclines the body slightly forward from the waist, arms very firm, fingers shut tight on the reins; and while the body inclines forward there should be no outward or lateral curvature of the spine, nor should the head be dropped. The shoulders pressed well back, and the hands close to the waist, will give firmness and suppleness to the whole figure. Directly the master is satisfied with the pupil's position, he should place his left hand under her right elbow, urge his own horse smartly on, and give the word "Trot," on which the pupil should, without altering her position or yielding her hand, touch her horse smartly on the shoulder with the whip; he will then trot forward. At the first step he takes the master should help the pupil up with his left hand, and commence counting his "one," "two" in exact accordance with the horse's action. In nine cases out of ten the lady will succeed, with a fair stepping horse, in catching at the first attempt the rise at the right moment, and the increased impetus given by the horse will assist her, while her preparatory lessons in rising and falling will now prove their value.
