The girl was standing before the Heart-machine of the city. Her smile was cool and silver. She stretched out her hand, which was more delicate than glass, she seized the weighty lever, which was set to “Safety.” She pressed the lever round, still smiling, then walked out, with light, mad, step. Behind her the machine began to race. Above the deep mysteries of its delicate joints, like the sun’s disc—like the halo of a divine being—stood the silver racing wheel, the spokes of which appeared, in the whirl of revolution, as a single circling disc. The heart of Metropolis, Joh Fredersen’s city, began to run up a temperature, seized by a deadly illness.... CHAPTER XVI “Father—!!” Joh Fredersen’s son knew quite well that his father could not hear him, for he, the son, was standing in the lowest part of the pedestal of the New Tower of Babel, whither the twitching pulse of the street had thrown him, and his father was high, high, above the boiling of the city, the untouched brain, in the cool brain-pan. But yet he shouted for him and had to shout, and his shout, itself, was a cry for help and an accusation. The round structure of the New Tower of Babel was throwing up people who pushed out into the street, laughing as if insane. They were sucked up by the pulp of those in the street. The New Tower of Babel was deserted. Those who had occupied its rooms and passages—those who had been poured by the buckets of the Pater-noster works down to the depths, up to the heights—who had taken up their positions on the stairs—who had received instructions and passed them on—who had suffocated amidst figures—who had listened in to the whispers of the world—all, all streamed out from the New Tower of Babel as blood streams out from a cut vein, until it stood there, horribly empty—bled white. But the machines went on living. Yes, they seemed to be coming to life for the first time. Freder, who stood—a crumb of humanity—alone, in the hugeness of the round structure, heard the soft, deep, rushing howl, like the breath of the New Tower of Babel, growing louder and louder, clearer and clearer, and he saw, on turning round, that the empty cells of the Pater-noster were speeding more and more rapidly, more and more hurriedly, upwards and downwards. Yes, now it was as if these cells, these empty cells, were dancing upwards and downwards and the howling which trans-sected the New Tower of Babel seemed to proceed from out their empty jaws. “Father—!!” shouted Freder. And the whole round structure roared with him, with all its lungs. Freder ran, but not to the heights of the Tower. He ran to the depths, driven by horror and curiosity—down into the hell—guided by luminous pillars—to the abode of the Pater-noster machine, which was like Ganesha, the god with the elephant’s head.
