As soon as he could do so without an actual breach of politeness, de Sigognac took his leave, and retiring to his own chamber locked himself in; then took an ancient sword out of the woollen case in which he kept it to preserve it from rust—­his father’s sword—­which he had brought with him from home, as a faithful friend and ally.  He drew it slowly out of the scabbard, kissing the hilt with fervent affection and respect as he did so, for to him it was sacred.  It was a handsome weapon, richly, but not too profusely, ornamented—­a sword for service, not for show; its blade of bluish steel, upon which a few delicate lines of gold were traced, bore the well-known mark of one of the most celebrated armourers of Toledo.  The young baron examined the edge critically, drawing his fingers lightly over it, and then, resting the point against the door, bent it nearly double to test its elasticity.  The noble blade stood the trial right valiantly, and there was no fear of its betraying its master in the hour of need.  Delighted to have it in his hand again, and excited by the thought of what was in store for it and himself, de Sigognac began to fence vigorously against the wall, and to practise the varius thrusts and passes that his faithful old Pierre, who was a famous swordsman, had taught him at Castle Misery.  They had been in the habit of spending hours every day in these lessons, glad of some active occupation, and the exercise had developed the young baron’s frame, strengthened his muscles, and greatly augmented his natural suppleness and agility.  He was passionately fond of and had thoroughly studied the noble art of fencing, and, while he believed himself to be still only a scholar, had long been a master in it—­a proficient, such as is rarely to be found, even in the great cities.  A better instructor than old Pierre he could not have had—­not in Paris itself—­and buried though he had been in the depths of the country, entirely isolated, and deprived of all the usual advantages enjoyed by young men of his rank, he yet had become, though perfectly unconscious of it, a match for the most celebrated swordsmen in France—­that is to say, in the world—­able to measure blades with the best of them.  He may not have had all the elegant finish, and the many little airs and graces affected by the young sprigs of nobility and polished men of fashion in their sword-play, but skilful indeed must be the blade that could penetrate within the narrow circle of flashing steel in which he intrenched himself.  Finding, after a long combat with an imaginary foe, that his hand had not lost its cunning, and satisfied at length both with himself and with his sword, which he placed near his bedside, de Sigognac was soon sleeping soundly, and as quietly as if he had never even dreamed of sending a challenge to that lofty and puissant nobleman, the Duke of Vallombreuse.
