I nodded, and again his hands moved over the car's intricate controls. He turned a large knob, and a rising, purring whine filled the car, while outside there was a growing roar of sudden wind. At the same time there came to me a staggering sensation of falling, and for a moment I seemed to be plunging helplessly down into unfathomable abysses. It lasted but an instant, and when my mind cleared, I heard the winds outside the car shouting with higher and higher intensity, caused, as I knew, by our swift passage through time. I looked down into the streets below, and for a second could see no obvious changes, then noted that the autos and people seemed to have suddenly vanished. In place of them were misty blurs of undefined motion, and even these vanished as our progress on through time grew greater. The winking electric signs of the city had ceased to flash on and off, and appeared to be steadily illuminated. I looked up, through one of the glasses in the car's top surface, and then gasped, prepared as I was for what I saw. The whole firmament was moving, its starry hosts moving slowly but visibly toward the west. Steadily it turned, and in hardly more than a minute a gray light began to grow over the eastern horizon, flushing swiftly to rose. Then, from the center of the growing light, sprang up the sun, crimson and mighty, leaping up above the horizon in a single bound, it seemed, and moving swiftly, ever more swiftly, up toward the zenith. The winds had steadily risen to a cyclonic gale, and now I heard Lantin's voice, striving to make itself heard above them. "We're going through time all right," he shouted, his voice thin and piping in sound, above the roar of the gale. "We may as well head west now, too." I did not answer, but saw the buildings and streets below slide away to the east, as the car moved off in the opposite direction. By now the sun had traversed its whole circuit in the sky and was tumbling down behind the western heights. Before we had crossed above the Hudson, darkness had plunged down upon us, and as we rocketed over the Jersey meadows, I saw the stars again wheeling across the sky, but much faster than before. Our time-speed was steadily accelerating, now, as Lantin turned on more and more of the time-wave's power, and I knew that shortly we would be racing through the years with lightning speed. Again the cycle of darkness and dawn was repeated, with the sun hurtling across the sky faster and faster, while the winds of our double progress through time and space were deafening. Day and night followed each other so rapidly that I could obtain but vague glimpses of the ground below us. We were progressing through space at the rate of a hundred and fifty miles an hour, holding an even altitude of a mile above the earth's surface.
