The engine room looked like some of the atomic power stations he'd seen. Only smaller. There was no heavy concrete shielding, no lead walls. There was shielding around the central pile, and Gene knew that inside it was the hell of atomic chain reaction under the control of the big levers that moved the cadmium bars. There was a steam turbine at one end, and a huge boiler at the other. Gene didn't even try to guess how the pile activated the jets that drove the space ship. Somehow it "burned" the water.

This pile had been illegal from the first. Obviously some official had been bribed to permit the first use of it on a spaceship. Certainly no one who knew anything about the subject would have allowed human beings to work around a thing like this.

Gene's skin crawled and prickled with the energies that saturated the room. Little sparks leaped here and there, off his fingertips, off his nose.

The Chief Engineer was on a metal platform above the machinery level. The face had hair all over it, even on the eyelids. The eyes, popping weirdly, were double. They looked as if second eyes had started growing inside the original ones. They weren't reasonable; they weren't even sane. The look of them made Gene sick.

The Engineer shook his head back and forth to focus the awful, mutilated eyes. His voice was infinitely weary, strangely muffled. "Another sacrifice to Moloch, an's the pity! So they put you down here, as if there was anything to be done? Well, it'll be nice to work with someone who still has his buttons—as long as they last. Sit down."

Gene sat down and the metal chair gave him a shock that made him jump. "I don't know anything about this kind of work."

The man shrugged, "Who does? The pile runs itself. Ain't enough of it moves to need much greasing. You ought to be able to find the grease cups—they're painted red. Fill them, wipe off the dust, and wait. Then do it over again."

"What's the score on this bucket?"

"We're all signed on with a billy to the knob. And kept aboard by a guard system that's pretty near perfect. After awhile the emanations get to our brains and we don't care anymore. Then we're trusted employees. Only reason I don't blow her loose, it wouldn't do any good."
