It was an astonishing vision that began presently to open before him--scarcely beautiful except for its strangeness, and as unreal as a raised map. Far to his right, as he could see through the glass doors, lay the grey line of the sea against the luminous sky, rising and falling ever so slightly as the car, apparently motionless, tilted imperceptibly against the western breeze; the only other movement was the faint pulsation of the huge throbbing screw in the rear. To the left stretched the limitless country, flitting beneath, in glimpses seen between the motionless wings, with here and there the streak of a village, flattened out of recognition, or the flash of water, and bounded far away by the low masses of the Umbrian hills; while in front, seen and gone again as the car veered, lay the confused line of Rome and the huge new suburbs, all crowned by the great dome growing every instant. Around, above and beneath, his eyes were conscious of wide air-spaces, overhead deepening into lapis-lazuli down to horizons of pale turquoise. The only sound, of which he had long ceased to be directly conscious, was that of the steady rush of air, less shrill now as the speed began to drop down--down--to forty miles an hour. There was a clang of a bell, and immediately he was aware of a sense of faint sickness as the car dropped in a glorious swoop, and he staggered a little as he grasped his rugs together. When he looked again the motion seemed to have ceased; he could see towers ahead, a line of house-roofs, and beneath he caught a glimpse of a road and more roofs with patches of green between. A bell clanged again, and a long sweet cry followed. On all sides he could hear the movement of feet; a guard in uniform passed swiftly along the glazed corridor; again came the faint nausea; and as he looked up once more from his luggage for an instant he saw the dome, grey now and lined, almost on a level with his own eyes, huge against the vivid sky. The world span round for a moment; he shut his eyes, and when he looked again walls seemed to heave up past him and stop, swaying. There was the last bell, a faint vibration as the car grounded in the steel-netted dock; a line of faces rocked and grew still outside the windows, and Percy passed out towards the doors, carrying his bags.
