Nevertheless, if I could see nothing of what was passing on board, I could hear the noises of the machinery. I had first the feeling that our craft, its bow slightly raised, lost contact with the earth. Some swerves and balancings in the air followed. Then the turbines underneath spun with prodigious rapidity, while the great wings beat with steady regularity. Thus the “Terror,” probably forever, had left the Great Eyrie, and launched into the air as a ship launches into the waters. Our captain soared above the double chain of the Alleghanies, and without doubt he would remain in the upper zones of the air until he had left all the mountain region behind. But in what direction would he turn? Would he pass in flight across the plains of North Carolina, seeking the Atlantic Ocean? Or would he head to the west to reach the Pacific? Perhaps he would seek, to the south, the waters of the Gulf of Mexico. When day came how should I recognize which sea we were upon, if the horizon of water and sky encircled us on every side? Several hours passed; and how long they seemed to me! I made no effort to find forgetfulness in sleep. Wild and incoherent thoughts assailed me. I felt myself swept over worlds of imagination, as I was swept through space, by an aerial monster. At the speed which the “Terror” possessed, whither might I not be carried during this interminable night? I recalled the unbelievable voyage of the “Albatross,” of which the Weldon Institute had published an account, as described by Mr. Prudent and Mr. Evans. What Robur, the Conqueror, had done with his first airship, he could do even more readily with this quadruple machine. At length the first rays of daylight brightened my cabin. Would I be permitted to go out now, to take my place upon the deck, as I had done upon Lake Erie? I pushed upon the hatchway: it opened. I came half way out upon the deck. All about was sky and sea. We floated in the air above an ocean, at a height which I judged to be about a thousand or twelve hundred feet. I could not see Robur, so he was probably in the engine room. Turner was at the helm, his companion on the look-out. Now that I was upon the deck, I saw what I had not been able to see during our former nocturnal voyage, the action of those powerful wings which beat upon either side at the same time that the screws spun beneath the flanks of the machine. By the position of the sun, as it slowly mounted from the horizon, I realized that we were advancing toward the south. Hence if this direction had not been changed during the night this was the Gulf of Mexico which lay beneath us.
