He had the resolution to stop with this. He had often heard that shipwrecked persons had died through having eagerly devoured too much food. Edmond replaced on the table the bread he was about to devour, and returned to his couch⁠—he did not wish to die. He soon felt that his ideas became again collected⁠—he could think, and strengthen his thoughts by reasoning. Then he said to himself:

“I must put this to the test, but without compromising anybody. If it is a workman, I need but knock against the wall, and he will cease to work, in order to find out who is knocking, and why he does so; but as his occupation is sanctioned by the governor, he will soon resume it. If, on the contrary, it is a prisoner, the noise I make will alarm him, he will cease, and not begin again until he thinks everyone is asleep.”

Edmond rose again, but this time his legs did not tremble, and his sight was clear; he went to a corner of his dungeon, detached a stone, and with it knocked against the wall where the sound came. He struck thrice.

At the first blow the sound ceased, as if by magic.
