The muted thrumming of the atomic motor gradually worked its way into Joe's consciousness. He moved wearily, and then his mind, short-circuited by the ravages of the fever, cleared itself and he became aware of his surroundings.

How long he'd lain there, Joe couldn't tell as he staggered to his feet and toward the door. He had the answer, if he could make Bairn listen.

His glazed eyes stared around the power room. There was no one there. He weaved toward the water gauge, stared at it for a long time before it registered.

Why, his mind said dully, the tank's almost empty. Joe staggered for the door. The door was a ton weight that fought against him to open it. When it finally opened, he left it that way.

He got outside in the passageway, and his stomach rebelled. He was very sick for many moments. He crawled and staggered up the circular stairway toward the pilot's cubicle.

His body was bruised and hurting from the many times his weak legs had betrayed him before he reached the door to the cubicle. He couldn't move the lever to the door.

He tried to shout, but his voice was hoarse, weak. He pounded with both hands against the thick metal. But there was no answer. Once again, he was sick.

Then wearily he retraced his footsteps, pounded lengthily on each door with his weakened muscles. They couldn't hear him, a bitter voice nagged at him. He had the answer, and they wouldn't listen.

He didn't feel the pain as he rolled down the circular steps and lay at the bottom in a heap. Somehow he moved on, crawling.

If they couldn't listen, he'd have to do it. He reached the door to the power room, lifted his body across the threshold, and then weakness held him motionless.
