"And your guns?"
"Are air guns, also my own invention. I have several, and each is prepared to fire twenty shots by a mere movement of the trigger, the requisite force of air being placed in a hollow of the butt end; but all these mysteries will become plain to you before you have been long with me," answered Captain Vindex.

"If you want to give me a treat," said Mont, "I wish you would go up to the surface and let me have a look at the sea, and breathe the fresh air."
"Certainly. Come with me to the engine room."
Mont rose, and followed his conductor through several iron passages to the place where the machinery was fitted up.
A negro saluted the captain.
