Resuming their progress, he explained to Gay that his horses did one thing only--the trotters only trotted, the jumpers only jumped, and the horses went through special courses of medicine, and special courses of food on a strict system. To train a horse so that he shall be both heavy and fit, requires a refinement of training to which only the Americans have attained, and at Elsinore the most elaborate system of discipline was carried out, but in a kindly spirit, and the horse prepared for the life he had to lead. He took her off to the breeding paddocks, that had a lot of both American ex-champion trotting and "Pace and Action" mares, and also prize hackney mares, all with foals by trotters and hackneys, his idea being to breed, besides racing trotters, for racing on the Continent, show horses which should have more speed and quality than the hackney, whilst retaining their action, and to this end he crossed the American trotter with the hackney. "If my attempts to improve the English hackney by giving him some of the pace and action of the fast trotting horse should be crowned with success, I shall be satisfied," he told Gay, and he pointed out a foal that looked like a thoroughbred, and moved like a trotter with hackney action. In fact, most of these cross-bred foals looked the ideal carriage horse--good whole colours, great quality, long necks, very high action, great speed, and perfect manners, and there was never any difficulty in breaking them. Then came an inspection of the racing sulkies, which had an extra low seat so as to come round the turns better; then there were the long-shaft sulkies for a horse who has high action, and makes the ordinary sulky bob up and down, the jogging carts for exercising in, and the four-wheeled, single-seated racing wagons, called speed wagons, used by gentlemen driving in the States for Matinée or Amateur Trotting races. This obviates the necessity of spreading the legs apart on each side of the horse, and for some horses this does not diminish their speed, in fact they can go faster in a wagon than in a sulky, in spite of the extra weight, as it runs smoother, and does not hamper them. Rensslaer next took Gay to the outdoor training school, which is specially designed for the education of jumpers, on the inner side of which was a platform from which the attendants controlled them, and she watched them run loose on the track, jumping heavy tree trunks, fences, and other obstacles, and if they failed in their riderless freedom to clear them, they gained experience in the tumble that ensued, which served them well later.
