The shudder came again, stronger this time. A long, protracted groan followed it, traveling in a heavy wave through the bedrock of the city. The sound brought Proctors and serfs alike boiling out of the buildings.
At the third shock, something toward the center of the city collapsed with a sullen roar. Amalfi was caught up in the aimless, terrified eddying of the crowd, and fought, with hands, teeth and bullet head—
The groaning grew louder. Abruptly, the ground bucked. Amalfi pitched forward. With him went the whole milling mob, falling in windrows like stacked grain. There was frantic screaming everywhere, but it was worse inside the buildings. Over Amalfi’s head a window shattered explosively, and a woman’s body came twisting and tumbling through the shuddering air.
Amalfi heaved himself up, spitting blood, and ran again. The pavement ahead was cracked in great, irregular shards, like a madman’s mosaic. Just beyond, the blocks were tilted all awry, reminding Amalfi irrelevantly of a breakwater he had seen on some other planet, in some other century-He was clambering over them before he realized that these could only mark the rim of the original city of IMT. There were still more buildings on the other side of the huge, rockfilled trench, but the trench itself showed where the perimeter of the ancient Okie had been sunk into the soil of the planet. Fighting for air with saw-edged rales, he threw himself from stone to stone toward the far edge of the trench. This was the most dangerous ground of all; if IMT were to lift now, he would be ground as fine as mincemeat in the tumbling rocks. If he could just reach the marches of the Barrens—
Behind him, the groaning rose steadily in pitch, until it sounded like the tearing of an endless sheet of metal. Ahead, across the Barrens to the east, his own city gleamed in the last rays of the twin suns. There was fighting around it; little bright flashes were sputtering at its edge. The rockets Amalfi had heard, four of them, were arrowing across the sky, and black things dropped from them. The Okie city responded with spouts of smoke.
Then there was an unbearably bright burst. After Amalfi could see again, there were only three rockets. In another few seconds there wouldn’t be any: the City Fathers never missed.
Amalfi’s lungs burned. He felt sod under his sandals. A twisted runner of furze lashed across his ankle and he fell again.
He tried to get up and could not. The seared turf, on which an ancient rebel city once had stood, rumbled threateningly. He rolled over. The squat towers of IMT were swaying, and all around the edge of the city, huge blocks and clods heaved and turned over, like surf. Impossibly, a thin line of light, intense and ruddy, appeared above the moiling rocks. The suns were shining under the city—
The line of light widened. The old city took the air with an immense bound, and the rending of the long-rooted foundations was ear-splitting. From the sides of the huge mass, human beings threw themselves desperately toward the Barrens; all those Amalfi saw were serfs. The Proctors, of course, were still trying to control the flight of IMT—
The city rose majestically. It was gaining speed. Amalfi’s heart hammered. If Heldon and his crew could figure out in time what Amalfi had done to the controls, Karst’s old ballad would be re-enacted, and the crushing rule of the Proctors made safe forever.
