a horse with a peculiar gait. First the two feet on one side are lifted, then the two feet on the other. It is said that U. S. Grant was fond of a pacing horse, and that when a boy he taught the horses on the farm to pace, but that he could not be induced to train horses for the neighbors. One neighbor hit upon the ruse of employing Ulysses to go on a long errand with one of his horses, and, as he expected, the lad trained the horse to pace ere he got back. See HORSE RACING.
