Thus speaking, he recklessly stepped on the beam, and, despite the remonstrances of his companions, was in the act of proceeding along it, when his arm was firmly grasped, and a low, deep-toned voice exclaimed, "My lord, do you court a horrible death? Do not thus risk your life for naught." The individual who thus unhesitatingly interfered was evidently unknown to all present, being a casual visitor to the castle, who had just joined the group. With an imprecation, the madcap youngster jerked his arm away, and sprang forward along the beam. Its surface was rough, rounded, and uneven; and as he ran along, swerving from side to side, every instant in danger of being precipitated downward, with the awful certainty of being dashed to pieces, his friends could hardly restrain themselves from shrieking with terror, though such a course would probably have had the immediate effect of discomposing the equilibrium of their rash companion, and so inducing the catastrophe they fully anticipated, without the power of prevention. Had the adventurer's presence of mind one moment failed--had his self-possession and confidence wavered or forsaken him--had his brain sickened, or his eyes turned dim for a single second--had he made the least false step--had his footing slipped on the slimy surface of the beam--had he tripped against any of the knots projecting from the rotten wood which had mouldered away around them--at once would he have been hurled into dread eternity. But an unseen hand sustained him, and safely he reached the extremity of the beam, ruthlessly wrenched the trembling owl from its perch, waved it aloft in triumph, and then, with a proud ejaculation, began to retrace his steps, with it shrieking and fluttering in his hands. When he reached the centre of the frail beam, which creaked and bent terribly with his comparatively small weight, he paused, drew himself up to his full height--air above, air beneath, air all around, naught but air--and deliberately tore the head of the owl by main force from its body. Having perpetrated this cruel deed, he tossed the bloody head among the breathless spectators, and sharply dashed the writhing body into the void beneath his feet. He coolly watched its descent, until it lay a shapeless mass on the stones below; then, with slow, bravadoing mien, he walked back to his terrified party, and boastingly demanded of them whether they thought "Manners could beat that?" "My lord," solemnly said the stranger, "you have not performed the act either of a brave or a sane man, and you have committed a despicable deed on one of God's helpless creatures. You ought to thank Him, my lord, from the depth of your soul, that he saved you from the penalty you incurred." "What do you say?" fiercely demanded Lord Swindon. "Do you dare to insinuate cowardice against me?" and with flashing brow, he assumed a threatening attitude.
