Through the widely-opened panel, the liquid mass was bright with electricity, which was distributed with such uniformity that not a shadow, not a gradation, was to be seen in our manufactured light. The Nautilus remained motionless, the force of its screw subdued by the inclination of its planes: the instrument was propped on the bottom of the oceanic site, and in a few seconds we had obtained a perfect negative. But, the operation being over, Captain Nemo said, “Let us go up; we must not abuse our position, nor expose the Nautilus too long to such great pressure.” “Go up again!” I exclaimed. “Hold well on.” I had not time to understand why the Captain cautioned me thus, when I was thrown forward on to the carpet. At a signal from the Captain, its screw was shipped, and its blades raised vertically; the Nautilus shot into the air like a balloon, rising with stunning rapidity, and cutting the mass of waters with a sonorous agitation. Nothing was visible; and in four minutes it had shot through the four leagues which separated it from the ocean, and, after emerging like a flying-fish, fell, making the waves rebound to an enormous height.
