Meantime Gilbert, crossing his arms upon his breast, advanced slowly towards the bulldog, keeping his eyes steadily fixed on those of the animal, and when he thought he had disconcerted him by his undaunted gaze sufficiently to make him relax his grip upon the prize, he suddenly tore the glove from him and waved it in the air with his right hand. At the same moment Vorace, with a howl of rage, bounded up to leap at the throat of his despoiler. Gilbert sprang back, covering himself with his left arm, and the dog's jaws only grazed his shoulder. Yet when he touched the ground again, he held between his teeth a long strip of cloth, a scrap of linen, and a morsel of bloody flesh. Mad with fury the bulldog rolled over on the grass with this prize which he could hardly devour, and then suddenly, as if seized with a paroxysm of frenzy, he moved towards the castle doubling upon himself; but reaching the foot of the turret, he looked for his enemy and returned like an arrow, to pounce upon him again. "Throw down the glove," cried Ivan, "and climb the ash." "I will surrender the glove only to him who asked me for it," answered Gilbert. And hiding it in his bosom, he drew a knife from his pocket. He had not time to open it. The dog, with bristling hair and foaming jaws, was already within three steps of him, gathering himself to spring upon him; but he had scarcely raised himself from the ground when he fell back with his head shattered. The hatchet which Ivan carried at his girdle had come down upon him like a flash. The terrible animal vainly attempted to rise, rolled writhing in the dust, and breathed out his life with a hoarse and fearful howl. XIII Doctor Vladimir Paulitch arrived at the castle just in time to take care of Gilbert. The wound was wide and deep, and in consequence of the great heat which prevailed, it might easily have proved serious; fortunately, Doctor Vladimir was a skillful man, and under his care the wound was soon healed. He employed certain specifics, the uses of which were known only to himself, and which he took care to keep a secret from his patient. His medicine was as mysterious as his person.
