Even as he watched, the number changed to “34.” That at least was useful information, though because he had no idea of the machine’s speed it told him nothing about the length of the journey. The walls of the tunnel were one continual blur of grey, and the only sensation of movement was a very slight vibration he would never have noticed had he not been expecting it.
Diaspar must be many miles away by now, and above him would be the desert with its shifting sand dunes. Perhaps at this very moment he was racing beneath the broken hills he had watched as a child from the Tower of Loranne.
His thoughts came back to Lys, as they had done continually for the past few days. He wondered if it still existed, and once again assured himself that not otherwise would the machine be carrying him there. What sort of city would it be? Somehow the strongest effort of his imagination could only picture another and smaller version of Diaspar.
Suddenly there was a distinct change in the vibration of the machine. It was slowing down-there was no question of that. The time must have passed more quickly than he had thought: somewhat surprised, Alvin glanced at the indicator.
Lys 23 MINUTES
Feeling very puzzled, and a little worried, he pressed his face against the side of the machine. His speed was still blurring the walls of the tunnel into a featureless grey, yet now from time to time he could catch a glimpse of markings that disappeared almost as quickly as they came. And at each appearance, they seemed to remain in his field of vision for a little longer.
Then, without any warning, the walls of the tunnel were snatched away on either side. The machine was passing, still at a very great speed, through an enormous empty space, far larger even than the chamber of the moving ways.
Peering in wonder through the transparent walls, Alvin could glimpse beneath him an intricate network of guiding rods, rods that crossed and crisscrossed to disappear into a maze of tunnels on either side. Overhead, a long row of artificial suns flooded the chamber with light, and silhouetted against the glare he could just make out the frameworks of great carrying machines. The light was so brilliant that it pained the eyes, and Alvin knew that this place had not been intended for Man. What it was intended for became clear a moment later, when his vehicle flashed past row after row of cylinders, lying motionless above their guide-rails. They were larger than the machine in which he was travelling, and Alvin realized that they must be freight transporters. Around them were grouped incomprehensible machines, all silent and stilled.
Almost as quickly as it had appeared, the vast and lonely chamber vanished behind him. Its passing left a feeling of awe in Alvin’s mind: for the first time he really understood the meaning of that great, darkened map below Diaspar. The world was more full of wonder than he had ever dreamed.
Alvin glanced again at the indicator. It had not changed: he had taken less than a minute to flash through the great cavern. The machine was accelerating again, although there was still no sense of motion. But on either side the tunnel walls were flowing past at a speed he could not even guess.
