He hung up. "All right; let's get on with it," he said. "Ben, you get them into the lunch room; there are enough tables and benches in there for everybody to take the written test in two relays." "The union's gotta be represented while these tests is going on," the union steward announced. "Mr. Crandall says I'm to stay here an' watch what you do to these guys." "This man working for us?" Melroy asked Puryear. "Yes. Koffler, Julius. Electrical fitter; Joe Ricci's gang." "All right. See to it that he gets placed in the first relay for the written test, and gets first turn for the orals. That way he can spend the rest of his time on duty here for the union, and will know in advance what the test is like." He turned to Koffler. "But understand this. You keep your mouth out of it. If you see anything that looks objectionable, make a note of it, but don't try to interfere." The written tests, done on printed forms, required about twenty minutes. Melroy watched the process of oral testing and personal interviewing for a while, then picked up a big flashlight and dropped it into his overcoat pocket, preparatory to going out to inspect some equipment that had been assembled outside the reactor area and brought in. As he went out, Koffler was straddling a chair, glowering at Doris Rives and making occasional ostentatious notes on a pad. * * * * * For about an hour, he poked around the newly assembled apparatus, checking the wiring, and peering into it. When he returned to the temporary office, the oral testing was still going on; Koffler was still on duty as watcher for the union, but the sport had evidently palled on him, for he was now studying a comic book. Melroy left the reactor area and returned to the office in the converted area. During the midafternoon, somebody named Leighton called him from the Atomic Power Authority executive office, wanting to know what was the trouble between him and the I.F.A.W. and saying that a protest against his alleged high-handed and arbitrary conduct had been received from the union. Melroy explained, at length. He finished: "You people have twenty Stuart tanks, and a couple of thousand soldiers and cops and undercover-men, here, guarding against sabotage. Don't you realize that a workman who makes stupid or careless or impulsive mistakes is just as dangerous to the plant as any saboteur? If somebody shoots you through the head, it doesn't matter whether he planned to murder you for a year or just didn't know the gun was loaded; you're as dead one way as the other. I should think you'd thank me for trying to eliminate a serious source of danger." "Now, don't misunderstand my position, Mr. Melroy," the other man hastened to say. "I sympathize with your attitude, entirely. But these people are going to make trouble."
