Constans took steady aim, and, to his surprise, missed again, the bullet flying wide. The failure nettled him. He made his preparations for the third essay with care, raising and lowering the pistol several times, until he was sure that he could not miss the mark. A third failure--the bullet clipping a splinter from a fence-post on the opposite side of the ring. A mist rose before Constans's eyes; what did it mean? Could he have deceived himself in thinking that he had mastered this secret of the ancients? Was it to fail him now, when all depended upon success? His hand trembled so that he could hardly draw the trigger. The hammer fell for the fourth time, but no explosion followed, the cartridge having missed fire. He had now but one shot left, and the whispers of disapproval and disappointment among the crowd were plainly audible. Without stopping to reflect, Constans leaped over the rail of the gallery to the arena below. As he jumped, the girl, Alexa, started, and a cry escaped her parted lips; it was a sigh rather than an exclamation, the voice of a crushed flower suspiring its last vital breath. And Constans did not hear. For perhaps half a dozen seconds man and beast stood motionless, waiting upon each other. The bull tossed his head savagely, his tail twitching, and a cloud of dust and gravel rising under his impatient hoof. Constans, with finger on trigger, moved a step to the right so as to face him fairly. Suddenly the great horns came down with a vindictive sweep, the shoulders heaved in the first impulse of the coming charge. Like the snap of a whip the report rang out clean and sharp, and the bullet went home at just the one vulnerable point in the thick skull--that at which the butcher aims his pole-axe. The bull pulled up short, the glaring eyes softened as though in wonder at this strange performance that had been enacted before him; then, as the people still held their breath, the brute sank quietly to his knees and rolled over dead. A woman started in to laugh hysterically, but her voice was drowned in a mighty shout; like a wave the crowd passed over the barrier, and Constans grasped helplessly at half a hundred out-stretched hands. A babel of voices arose; the arena, filled to overflowing with excited men and women, was comparable only to some gigantic ant-hill. Fifty yards outside of the main palisade stood an oak-tree. Under the Stockader law no standing timber should have been permitted at a less distance than one hundred paces, but the oak was such a fine specimen that Red Oxenford had allowed it to remain--a fatal error.
