"Wait here," said Gamel to François. "I will by and by give thee a chance." François had, of course, been constantly in the room when the patrons were absent, and it was now familiar. It had been part of the old hotel of some extinct nobleman, and was of unusual height, and quite forty feet square, with tall windows at each end; a cushioned bench ran around the walls, and above it hung wire masks, foils, sabers, and a curious collection of the arms of past ages and barbarous tribes. Chiefly remarkable were the many fine blades, Spanish or Eastern. At the side of the hall, a doorway led into the shooting-gallery, a late adjunct since the English use of the pistol had been brought into the settlement of quarrels made savage by the angry politics of the day. On one of the walls of the fencing-room was a large sign on which was painted: "Achille Gamel, ci-devant Maître d'Armes, Régiment du Duc de Rohan-Chabot. Lessons in the small sword, saber, and pistol." The word "Duc" was chalked over, but was still easily to be made out.

Presently Gamel came to François in his shirt and breeches, foil in hand. "This way, François." As they slowly crossed the room, Gamel went on to say in a low tone of voice: "Don't be too eager. Take it all as a matter of course. Don't be nervous. One must have had a serious affair or two before one gets over the foil fever. Remember, you are here to teach, not to triumph. There are few here you cannot touch, but that is not business."

"I understand," said François.

"I will give you for your lesson the best blade in Paris. You can teach him nothing. He is my foster-brother, the Marquis de Ste. Luce."

"Ste. Luce!"

"Yes; he is here often."

As they approached, the great gentleman came to meet them, separating himself from the laughing group of younger men.

"Ma foi!" he exclaimed. "Is this your new blade, Gamel?" He caught François's appealing eye, and showed no sign of having known the thief until they were apart from the rest and had taken their foils. Then he said quietly, "Does Gamel know?"

"Yes, monsieur. I saved his life in a row in the Cité, and he gives me this chance."

"Good! I shall not betray you. But beware! You must keep faith, and behave yourself."
