I was congratulating myself on the prospect of escaping, when down came my steed once more; and as I was as unprepared for the accident as before, I was thrown over his head, and more severely injured than at first.  Still, though partly stunned, I could see what was taking place. I fancied that I was, at all events, sufficiently to the right of the herd to escape being trampled to death, when just then a huge bull, who must have had his eye upon me, wheeled from his companions, and, putting his head to the ground, made, as I thought, towards me.  To escape by mounting my horse was now out of the question, for I had been thrown too far to seize the reins, and the poor animal still lay struggling to get his feet out of the hole.  Any other than a prairie horse would have broken his legs, or sprained himself irretrievably.  Just when I expected to be trampled to death or gored by the bull's horns, I saw that the savage creature was making towards my horse instead of me; but as it reached the mustang, the latter drew his feet out of the hole, and throwing up his heels at the bull's nose, scampered off, followed by his enemy, while the rest of the herd swept by like a torrent, not ten yards from where I lay.  Some stragglers, however, caught sight of me; and another big bull was rushing on to give me a taste of his horns and hoofs, when a loud "Whallop-ahoo-aboo!  Erin go bragh!" sounded in my ears.
