“So long as it navigates horizontally,” Ned Land muttered, “I’ve no complaints. But if it gets the urge to dive, I wouldn’t give $2.00 for my hide!” The Canadian might have quoted a much lower price. So it was imperative to make contact with whatever beings were confined inside the plating of this machine. I searched its surface for an opening or a hatch, a “manhole,” to use the official term; but the lines of rivets had been firmly driven into the sheet-iron joins and were straight and uniform. Moreover, the moon then disappeared and left us in profound darkness. We had to wait for daylight to find some way of getting inside this underwater boat. So our salvation lay totally in the hands of the mysterious helmsmen steering this submersible, and if it made a dive, we were done for! But aside from this occurring, I didn’t doubt the possibility of our making contact with them. In fact, if they didn’t produce their own air, they inevitably had to make periodic visits to the surface of the ocean to replenish their oxygen supply. Hence the need for some opening that put the boat’s interior in contact with the atmosphere. As for any hope of being rescued by Commander Farragut, that had to be renounced completely. We were being swept westward, and I estimate that our comparatively moderate speed reached twelve miles per hour. The propeller churned the waves with mathematical regularity, sometimes emerging above the surface and throwing phosphorescent spray to great heights. Near four o’clock in the morning, the submersible picked up speed. We could barely cope with this dizzying rush, and the waves battered us at close range. Fortunately Ned’s hands came across a big mooring ring fastened to the topside of this sheet-iron back, and we all held on for dear life. Finally this long night was over. My imperfect memories won’t let me recall my every impression of it. A single detail comes back to me. Several times, during various lulls of wind and sea, I thought I heard indistinct sounds, a sort of elusive harmony produced by distant musical chords. What was the secret behind this underwater navigating, whose explanation the whole world had sought in vain? What beings lived inside this strange boat? What mechanical force allowed it to move about with such prodigious speed? Daylight appeared. The morning mists surrounded us, but they soon broke up. I was about to proceed with a careful examination of the hull, whose topside formed a sort of horizontal platform, when I felt it sinking little by little. “Oh, damnation!” Ned Land shouted, stamping his foot on the resonant sheet iron. “Open up there, you antisocial navigators!” But it was difficult to make yourself heard above the deafening beats of the propeller. Fortunately this submerging movement stopped. From inside the boat, there suddenly came noises of iron fastenings pushed roughly aside. One of the steel plates flew up, a man appeared, gave a bizarre yell, and instantly disappeared.
