"It is a pulley," replied Felworth; "but, since you are desirous to hear, I had better begin from the commencement, and tell you the entire history of this extraordinary animal, whose fame has reached Westminster Hall. The man who owns the coach which passes this house attended an auction in Dublin of cast horses from a dragoon regiment about a year and a half since, and among them was exhibited the horse before you. Of course he had managed to get a private opinion from the sergeant in charge; and the account he heard of my dark friend was, '_that they had had him only three months, and that he was an untamable devil_.' When a regiment could not subdue him, who could? Notwithstanding, from his superior shape, the proprietor bid for him, and purchased him for something under five pounds. When he took him to his stables, he found that the horse would not suffer an article of harness to be put on him. This was bad enough. However, some days after, by the assistance of all the men about the yard, they did succeed. The horse was allowed to remain in that state all night, and was put in as near-side wheeler in the coach which was to leave Dublin that morning. The proprietor himself undertook to drive him--for he is a famous hand in that way, and many a vicious horse has he brought to reason. By good luck I happened to be a passenger myself.--(Look, I beg of you, at the intelligence of his expression! He knows we are talking of him.) Well, as I said, I was on the coach, and beside the proprietor, while the regular coachman was immediately behind us. The horse started pretty fairly. To be sure he made a plunge or two, but the traces were strong, and his companions stout and steady. For several miles we came along as pleasantly as needs be, and never did I see a horse do his business in better style. It was during this period that I heard the horse's previous history; and further, I was told that, in the way of harnessing him, once the saddle was on his back, (though it was no easy task to get it there,) the remainder of the business had been easy. I hope you are not tired.--Well, as you wish me, I will finish my history. Just at the third milestone I felt a shock on the soles of my feet as if I had been receiving the bastinado. I need not say this was from the heels of Units on the under side of the board on which my feet rested. In a moment after, the performance was repeated, with this difference, that the blow was rather lower. But it was more serious; for on this occasion he struck the front-boot with such force, that he was unable to withdraw his foot, which went right through the board; and the consequence was, that he fell against the pole. Had the other wheel-horse not been as steady as a rock, we would have gone right over. As it was, the driver pulled up at once; and immediately the coachman and I were at the heads of the other horses. After several terrific struggles, Units contrived to disengage himself. You see the
