"It works as easily by pressure on the disc, which replaces the trigger, perfectly."

"That was your idea."

"After you put me on the track," returned the Italian, gratefully. "Oh, I am still very ignorant in these matters."

"Not more than I, a few months ago. I had not handled a firearm until—" he checked himself and frowned; then, tranquilly resuming, he said: "Labor, and you will reach the goal!"

Antonino looked on silently as his instructor took the gun and inserted the bullet, but when he was going over to the open window, with the evident intention to fire off into the garden, he followed and laid his hand on his arm, saying animatedly:

"Do not fire!"

"Why not?" returned Clemenceau, but without astonishment. "We live in a desert since we have frightened our neighbors away. For two leagues around, nobody is about at this hour and everybody within our walls is accustomed to the noise of the gas exploding."

"Not everybody," remonstrated Antonino. "Madame Clemenceau has returned home and the sound frightens her because so strange."

"It is so. That's another matter," replied the inventor, putting the rifle down in the corner without haste.

"Did you know it? Have you seen her?" cried Antonino, struck by the remarkable unconcern of his master.
