"I didn't recognize any," Applequist said impatiently. "Don't waste time. The whole mass of debris is apt to collapse. I have to work fast."

"Where is it? I want to see it!"

"I'm doing this alone. You supply the material and cover for my absence. That's your part."

Jenkins twisted uncertainly. "If you're lying to me, Applequist --"

"I'm not lying," Applequist answered angrily. "When can I expect the power unit?"

"Tomorrow morning. I'll have to fill out a bushel of forms. Are you sure you can operate it? I better send a repair team along with you. To be sure --"

"I can handle it." Applequist interrupted. "Just get me the stuff. I'll take care of the rest."

Morning sunlight filtered over the rubble and trash. Applequist nervously fitted the new power pack in place, screwed the leads tight, clamped the corroded shield over it, and then got shakily to his feet. He tossed away the old pack and waited.

The robot stirred. Its eye gained life and awareness. Presently it moved its arm in exploratory motions, over its damaged trunk and shoulders.

"All right?" Applequist demanded huskily.

"Apparently." The robot's voice was stronger; full and more confident. "The old power pack was virtually exhausted. It was fortunate you came along when you did."

"You say men lived in cities," Applequist plunged in eagerly. "Robots did the work?"

"Robots did the routine labor needed to maintain the industrial system. Humans had leisure to enjoy whatever they wanted. We were glad to do their work for them. It was our job."

"What happened? What went wrong?'

The robot accepted the pencil and paper; as it talked it carefully wrote down figures. "There was a fanaitic group of humans. A religious organiza­tion. They claimed that God intended man to work by the sweat of his brow. They wanted robots scrapped and men put back in the factories to slave away at routine tasks."

"But why?"

"They claimed work was spiritually ennabling." The robot tossed the paper back. "Here's the list of what I want. I'll need those materials and tools to restore my damaged system."

Applequist fingered the paper. "This religious group --"

"Men separated in two factions. The Moralists and the Leisurists. They fought each other for years, while we stood on the sidelines waiting to know our fate. I couldn't believe the Moralists would win out over reason and com­mon sense. But they did."

"Do you think --" Applequist began, and then broke off. He could hardly give voice to the thought that was struggling inside him. "Is there a chance robots might be brought back?"

"Your meaning is obscure." The robot abruptly snapped the pencil in half and threw it away. "What are you driving at?"

"Life isn't pleasant in the Companies. Death and hard work. Forms and shifts and work periods and orders."

"It's your system. I'm not responsible."

"How much do you recall about robot construction? What were you, before the war?"

"I was a unit controller. I was on my way to an emergency unit-factory, when my ship was shot down." The robot indicated the debris around it. "That was my ship and cargo."

"What is a unit controller?"

"I was in charge of robot manufacture. I designed and put into production basic robot types."

Applequist's head spun dizzily. "Then you do know robot construction."

"Yes." The robot gestured urgently at the paper in Applequist's hand. "Kindly get those tools and materials as soon as possible. I'm completely helpless this way. I want my mobility back. If a rocketship should fly over­head..."

"Communication between Companies is bad. I deliver my letters on foot. Most of the country is in ruins. You could work undetected. What about your emergency unit-factory? Maybe it wasn't destroyed."

The robot nodded slowly. "It was carefully concealed. There is the bare possibility. It was small, but completely outfitted. Self-sufficient."

"If I get repair parts, can you --"

"We'll discuss this later." The robot sank back down. "When you return, we'll talk further."

He got the material from Jenkins, and a twenty-four hour pass. Fasci­nated, he crouched against the wall of the ravine as the robot systematically pulled apart its own body and replaced the damaged elements. In a few hours a new motor system had been installed. Basic leg cells were welded into posi­tion. By noon the robot was experimenting with its pedal extremities.

"During the night," the robot said, "I was able to make weak radio contact with the emergency unit-factory. It exists intact, according to the robot moni­tor."

"Robot? You mean --"

"An automatic machine for relaying transmission. Not alive, as I am. Strictly speaking, I'm not a robot." Its voice swelled. "I'm an android."

The fine distinction was lost on Applequist. His mind was racing excit­edly over the possibilities. "Then we can go ahead. With your knowledge, and the materials available at the --"

"You didn't see the terror and destruction. The Moralists systematically demolished us. Each town they seized was cleared of androids. Those of my race were brutally wiped out, as the Leisurists retreated. We were torn from our machines and destroyed."

"But that was a century ago! Nobody wants to destroy robots any more. We need robots to rebuild the world. The Moralists won the war and left the world in ruins."

The robot adjusted its motor system until its legs were coordinated. "Their victory was a tragedy, but I understand the situation better than you. We must advance cautiously. If we are wiped out this time, it may be for good." Applequist followed after the robot as it moved hesitantly through the debris toward the wall of the ravine.

"We're crushed by work. Slaves in underground shelters. We can't go on this way. People will welcome robots. We need you. When I think how it must have been in the Golden Age, the fountains and flowers, the beautiful cities above ground... Now there's nothing but ruin and misery. The Moralists won, but nobody's happy. We'd gladly --"

"Where are we? What is the location here?"

"Slightly west of the Mississippi, a few miles or so. We must have free­dom. We can't live this way, toiling underground. If we had free time we could investigate the mysteries of the whole universe. I found some old scientific tapes. Theoretical work in biology. Those men spent years working on abstract topics. They had the time. They were free. While robots maintained the economic system those men could go out and --"

"During the war," the robot said thoughtfully, "the Moralists rigged up detection screens over hundreds of square miles. Are those screens still func­tioning?"

"I don't know. I doubt it. Nothing outside of the immediate Company shelters still works."

The robot was deep in thought. It had replaced its ruined eye with a new cell; both eyes flickered with concentration. "Tonight we'll make plans con­cerning your Company. I'll let you know my decision then. Meanwhile, don't bring this situation up with anyone. You understand? Right now I'm con­cerned with the road system."

"Most roads are in ruins." Applequist tried hard to hold back his excite­ment. "I'm convinced most in my Company are -- Leisurists. Maybe a few at the top are Moralists. Some of the supervisors, perhaps. But the lower classes and families --"

"All right," the robot interrupted. "We'll see about that later." It glanced around. "I can use some of that damaged equipment. Part of it will function. For the moment, at least."

Applequist managed to avoid Jenkins, as he hurriedly made his way across the organizational level to his work station. His mind was in a turmoil. Every­thing around him seemed vague and unconvincing. The quarreling supervi­sors. The clattering, humming machines. Clerks and minor bureaucrats hurrying back and forth with messages and memoranda. He grabbed a mass of letters and mechanically began sorting them into their slots.
