It was then that Lad disgraced himself and his deities, and proved himself all unworthy to appear in so refined an assembly. The man in livery had convoyed the bull to within a few feet of the proudly exhorting Glure. Now, without growl or other sign of warning, the hitherto peaceable dog changed into a murder machine. In a single mighty bound he cleared the narrowing distance between himself and the advancing groom. The leap sent him hurtling through the air, an eighty-pound furry catapult, straight for the man's throat. Over and beyond the myriad cattle odors, Lad had suddenly recognized a scent that spelt deathless hatred. The scent had been verified by a single glance at the brilliantly clad man in livery. Wherefore the mad charge. The slashing jaws missed their mark in the man's throat by a bare half inch. That they missed it at all was because the man also recognized Lad, and shrank back in mortal terror. Even before the eighty-pound weight, smashing against his chest, sent the groom sprawling backward to the ground, Lad's slashing jaws had found a hold in place of the one they had missed. This grip was on the liveried shoulder, into which the fangs sank to their depth. Down went the man, screaming, the dog atop of him. "Lad!" cried the Mistress, aghast. "_Lad!_" Through the avenging rage that misted his brain the great dog heard. With a choking sound that was almost a sob he relinquished his hold and turned slowly from his prey. The Master and Glure instinctively took a step toward the approaching dog and the writhingly prostrate man. Then, still more instinctively, and without even coming to a standstill before going into reverse, they both sprang back. They would have sprung further had not the roped walls of the show ring checked them. For Tenebris had taken a sudden and active part in the scene. The gigantic Holstein during his career in Europe had trebly won his title to champion. And during the three years before his exportation to America he had gored to death no fewer than three over-confident stable attendants. The bull's homicidal temper, no less than the dazzling price offered by Glure, had caused his owner to sell him to the transatlantic bidder. A bull's nose is the tenderest spot of his anatomy. Next to his eyes, he guards its safety most zealously. Thus, with a stout leading-bar between him and his conductor, Tenebris was harmless enough. But the conductor just now had let go of that bar, as Lad's weight had smitten him. Freed, Tenebris had stood for an instant in perplexity. Fiercely he flung his gnarled head to one side to see the cause of the commotion. The gesture swung the heavy leading-bar, digging the nose ring cruelly into his sensitive nostrils. The pain maddened Tenebris. A final plunging twist of the head--and the bar's weight tore the nose ring free from the nostrils.
