The Park afforded good leaping in those days. Some of the fences were still standing around the abandoned gardens, and new ditches and old brooks were plenty. Vixen gave me lessons in fencing which a few years later, in time of graver need, stood me in good stead. She weighed less than four times the weight that she carried; yet she cleared a four-foot fence with apparent ease, and once, in a moment of excitement, she carried me over a brook, with a clear leap of twenty-six feet, measured from the taking-off to the landing. Her feats of endurance were equal to her feats of strength. I once rode her from Yorkville to Rye (twenty-one miles) in an hour and forty-five minutes, including a rest of twenty minutes at Pelham Bridge, and I frequently rode twenty-five miles out in the morning and back in the afternoon. When put to her work, her steady road gallop (mostly on the grassy sides) was fifteen miles an hour. Of course these were extreme cases; but she never showed fatigue from them, and she did good service nearly every day, winter and summer, from her twelfth to her fifteenth year, keeping always in good condition, though thin as a racer, and looking like a colt at the end of the time. Horsemen never guessed her age at more than half of what it actually was. Beyond the average of even the most intelligent horses, she showed some almost human traits. Above all was she fond of children, and would quiet down from her wildest moods to allow a child to be carried on the pommel. When engaged in this serious duty, it was difficult to excite her, or to urge her out of a slow and measured pace, although usually ready for any extravagance. Not the least marked of her peculiarities was her inordinate vanity. On a country road, or among the workmen of the Park, she was as staid and business-like as a parson's cob; but let a carriage or a party of visitors come in sight, and she would give herself the prancing airs of a circus horse, seeming to watch as eagerly for some sign of approval, and to be made as happy by it, as though she only lived to be admired. Many a time have I heard the exclamation, "What a beautiful horse!" and Vix seemed to hear it too, and to appreciate it quite as keenly as I did. A trip down the Fifth Avenue in the afternoon was an immense excitement to her, and she was more fatigued by it than by a twenty-mile gallop. However slowly she travelled, it was always with the high springing action of a fast trot, or with that long-stepping, sidelong action that the French call _á deux pistes_; few people allowed her to pass without admiring notice.
