It seemed an age before that indefinable change of vibration occurred again. Now the indicator was reading:…

Lys 1 MINUTE

and that minute was the longest Alvin had ever known. More and more slowly moved the machine: this was no mere slackening of its speed. It was coming to rest at last.

Smoothly and silently the long cylinder slid out of the tunnel into a cavern that might have been the twin of the one beneath Diaspar. For a moment Alvin was too excited to see anything clearly. His thoughts were jumbled and he could not even control the door, which opened and closed several times before he pulled himself together. As he jumped out of the machine, he caught a last glimpse of the indicator. Its wording had changed and there was something about its message that was very reassuring:…

Diaspar 35 MINUTES

THE LAND OF LYS

It had been as simple as that. No one could have guessed that he had made a journey as fateful as any in the history of Man.

As he began to search for a way out of the chamber, Alvin found the first sign that he was in a civilization very different from the one he had left. The way to the surface clearly lay through a low, wide tunnel at one end of the cavern-and leading up through the tunnel was a flight of steps. Such a thing was almost unknown in Diaspar. The machines disliked stairways, and the architects of the city had built ramps or sloping corridors wherever there was a change of level. Was it possible that there were no machines in Lys? The idea was so fantastic that Alvin dismissed it at once.

The stairway was very short, and ended against doors that opened at his approach. As they closed silently behind him, Alvin found himself in a large cubical room which appeared to have no other exit. He stood for a moment, a little puzzled, and then began to examine the opposite wall. As he did so, the doors through which he had entered opened once more. Feeling somewhat annoyed, Alvin left the room again-to find himself looking along a vaulted corridor rising slowly to an archway that framed a semicircle of sky. He realized that he must have risen many hundreds of feet, but there had been no sensation of movement. Then he hurried forward up the slope to the sunlit opening.
