"First Tresor. It is a custom in the Bastille for the prisoner to take the name of his room—that saves the turnkey the trouble of remembering names; however, if the Bastille be full, and two or three prisoners in the same room, they take two numbers; for example: I am first Tresor, if you were put here you would be first Tresor number two; another would be first Tresor number three—the jailers have a kind of Latin literature for this."

"Yes, I understand," said Gaston, watching La Jonquiere intently; "then you are a prisoner?"

"Parbleu, you see for yourself; I presume we are neither of us here for pleasure."

"Then we are discovered."

"I am afraid so."

"Thanks to you."

"How to me?" cried La Jonquiere, feigning surprise. "No jokes, I beg."

"You have made revelations, traitor!"

"I! come, come, young man, you are mad; you ought not to be in the Bastille, but in the Petites Maisons."

"Do not deny it, M. d'Argenson told me!"
