In fact, he could not be ignorant that the attention of the public was now keenly fixed upon the Great Eyrie; and that some further attempt was likely to be made to penetrate it. Must he not fear that some day or other the effort would be successful, and that men would end by invading his hiding-place? Did he not wish that they should find there no single evidence of his occupation? The sun disappeared behind the crests of the Blueridge. His rays now lighted only the very summit of Black Dome towering in the northwest. Probably the “Terror” awaited only the night in order to begin her flight. The world did not yet know that the automobile and boat could also transform itself into a flying machine. Until now, it had never been seen in the air. And would not this fourth transformation be carefully concealed, until the day when the Master of the World chose to put into execution his insensate menaces? Toward nine o’clock profound obscurity enwrapped the hollow. Not a star looked down on us. Heavy clouds driven by a keen eastern wind covered the entire sky. The passage of the “Terror” would be invisible, not only in our immediate neighborhood, but probably across all the American territory and even the adjoining seas. At this moment Turner, approaching the huge stack in the middle of the eyrie, set fire to the grass beneath. The whole mass flared up at once. From the midst of a dense smoke, the roaring flames rose to a height which towered above the walls of the Great Eyrie. Once more the good folk of Morganton and Pleasant Garden would believe that the crater had reopened. These flames would announce to them another volcanic upheaval. I watched the conflagration. I heard the roarings and cracklings which filled the air. From the deck of the “Terror,” Robur watched it also. Turner and his companion pushed back into the fire the fragments which the violence of the flames cast forth. Little by little the huge bonfire grew less. The flames sank down into a mere mass of burnt-out ashes; and once more all was silence and blackest night. Suddenly I felt myself seized by the arm. Turner drew me toward the “Terror.” Resistance would have been useless. And moreover what could be worse than to be abandoned without resources in this prison whose walls I could not climb! As soon as I set foot on the deck, Turner also embarked. His companion went forward to the look-out; Turner climbed down into the engine-room, lighted by electric bulbs, from which not a gleam escaped outside. Robur himself was at the helm, the regulator within reach of his hand, so that he could control both our speed and our direction. As to me, I was forced to descend into my cabin, and the hatchway was fastened above me. During that night, as on that of our departure from Niagara, I was not allowed to watch the movements of the “Terror.”
