the same moment, a blast of intense, fiery, almost unbearable pain shot up his own arm. As he grasped his arm, sweat spurting out on his face, he heard screams from the box on his left and realized it was Director Cornelius who screamed. There were answering screams from around the hall. Then the pain suddenly subsided. Menesee started about, breathing raggedly. The pain-reaction had been severe enough to affect his vision; the great hall looked momentarily darker than it should have been. And although the actual pain had ended, the muscles of his arm and shoulder were still trying to cramp into knots. There was no more screaming. From the right came Director Ojeda's gasping voice. "What happened? Did something go wrong with the stimulating devices? We might all have been killed—!" Menesee didn't reply. Wherever he looked, he saw faces whitened with shock. Apparently everyone in the Tribunal Hall, from the administrator and Spokesman Dorn on down to the directors' attendants and the two guards flanking the prisoner's area, had felt the same thing. Here and there, men who had collapsed were struggling awkwardly back to their feet. He heard a hoarse whisper behind him. "Sir, Director Cornelius appears to have fainted!" Menesee glanced around, saw Cornelius' attendant behind the box, then Cornelius himself, slumped forward, face down and motionless, sprawling half across his table. "Let him lie there and keep quiet, fool!" Menesee ordered the man sharply. He returned his attention to the center of the hall as Spokesman Dorn announced in a voice which held more of an edge than was normal but had lost none of its strength and steadiness, "Before any moves are suggested, I shall tell you what has been done. "The Tribunal Hall has been sealed and further events in it will be monitored from without. No one will be able to leave until the matter with which we are now concerned here has been settled to the satisfaction of the Machine. "Next, any of you who believe that an instrument failure was involved in the experience we shared can disabuse themselves. The same effect was reported immediately from two other auditoriums on the Great Circuit, and it is quite possible that it was repeated in all of them." Rainbolt, grimacing and massaging his right arm vigorously, nodded. "It was repeated in all of them, sir!"
