When a man has a raw horse quite ignorant of
						leaping, he must get over the ditch himself first, holding him loosely by
						the leading-rein, and then give him a pull with the rein to make him leap
						over. If he refuses, let someone strike him as hard as he can with a whip or a
						stick: whereupon he will leap, and not only the necessary distance, but much
						further than was required. In future there will be no need to beat him, for
						if he merely sees a man approaching behind him, he will leap.
