In fact, I was already obliged to increase my respirations to eke out of this cell the little oxygen it contained, when suddenly I was refreshed by a current of pure air, and perfumed with saline emanations. It was an invigorating sea breeze, charged with iodine. I opened my mouth wide, and my lungs saturated themselves with fresh particles. At the same time I felt the boat rolling. The iron-plated monster had evidently just risen to the surface of the ocean to breathe, after the fashion of whales. I found out from that the mode of ventilating the boat. When I had inhaled this air freely, I sought the conduit-pipe, which conveyed to us the beneficial whiff, and I was not long in finding it. Above the door was a ventilator, through which volumes of fresh air renewed the impoverished atmosphere of the cell. I was making my observations, when Ned and Conseil awoke almost at the same time, under the influence of this reviving air. They rubbed their eyes, stretched themselves, and were on their feet in an instant. “Did master sleep well?” asked Conseil, with his usual politeness. “Very well, my brave boy. And you, Mr. Land?” “Soundly, Professor. But I don’t know if I am right or not; there seems to be a sea breeze!” A seaman could not be mistaken, and I told the Canadian all that had passed during his sleep.
