He had not remained three minutes in this posture of defence, when Pipes, who acted as the enemy's forlorn hope, advanced to the gate with great intrepidity, and, clapping his foot to the door, which was none of the stoutest, with the execution and despatch of a petard, split it into a thousand pieces. This sudden execution had an immediate effect upon the apprentice, who retreated with great precipitation, and escaped at a postern; but the master placed himself, like another Hercules, in the breach; and when Pipes, brandishing his cudgel, stepped forward to engage him, leveled his weapon with such force and dexterity at his head, that had the skull been made of penetrable stuff, the iron edge must have cleft his pate in twain. Casemated as he was, the instrument cut sheer even to the bone, on which it struck with such amazing violence, that sparks of real fire were produced by the collision. And let not the incredulous reader pretend to doubt the truth of this phenomenon, until he shall have first perused the ingenious Peter Kolben's Natural History of the Cape of Good Hope, where the inhabitants commonly used to strike fire with the shin-bones of lions which had been killed in that part of Africa. Pipes, though a little disconcerted, far from being disabled by the blow, in a trice retorted the compliment with his truncheon, which, had not his antagonist expeditiously slipped his head aside, would have laid him breathless across his own threshold; but, happily for him, he received the salutation upon his right shoulder, which crashed beneath the stroke, and the hoe dropped instantly from his tingling hand. Tom, perceiving, and being unwilling to forego, the advantage he had gained, darted his head into the bosom of this son of earth, and overturned him on the plain, being himself that instant assaulted by the mastiff, who fastened upon the outside of his thigh. Feeling himself incommoded by this assailant in his rear, he quitted the prostrate gardener to the resentment of his associates, who poured upon him in shoals, and turning about, laid hold with both his hands of this ferocious animal's throat, which he squeezed with such incredible force and perseverance, that the creature quitted his hold; his tongue lolled out of his jaws, the blood started from his eyes, and he swung a lifeless trunk between the hands of his vanquisher.
