“ Land?"
"Break out of here!"
"Breaking out of a prison on shore is difficult enough, but with an underwater prison, it strikes me as completely unworkable."
"Come now, Ned my friend," Conseil asked, "how would you answer master's objection? I refuse to believe that an American is at the end of his tether."
Visibly baffled, the harpooner said nothing. Under the conditions in which fate had left us, it was absolutely impossible to escape. But a Canadian's wit is half French, and Mr. Ned Land made this clear in his reply. ”

“ For my part, despite the harpooner's confident talk, I admit that I entertained no illusions. I had no faith in those promising opportunities that Ned Land mentioned. To operate with such efficiency, this underwater boat had to have a sizeable crew, so if it came to a physical contest, we would be facing an overwhelming opponent. Besides, before we could do anything, we had to be free, and that we definitely were not. I didn't see any way out of this sheet–iron, hermetically sealed cell. ”

“ I replied. "We have not fallen into the hands of cannibals."
"Just because they don't make a habit of it," the Canadian replied in all seriousness, "doesn't mean they don't indulge from time to time. Who knows? Maybe these people have gone without fresh meat for a long while, and in that case three healthy, well–built specimens like the professor, his manservant, and me—"
"Get rid of those ideas, Mr. Land," I answered the harpooner. "And above all, don't let them lead you to flare up against our hosts, which would only make our situation worse." ”

“ Although our cell was large, we obviously had used up most of the oxygen it contained. In essence, over an hour's time a single human being consumes all the oxygen found in 100 liters of air, at which point that air has become charged with a nearly equal amount of carbon dioxide and is no longer fit for breathing. ”
