"Put the switch in again, Anse; the damage is done and you won't make it any worse."

When the screens came on, he looked around from one to another. The two supervisors, big ovoid things like the small round ones they had used in repairing the power reactors the first day, were circling aimlessly near the roof, one clockwise and the other counterclockwise, dodging obstructions and getting politely out of each other's way. At lower altitude, a dozen assorted worker-robots were moving about, and more were emerging from cells at the end of the building. Sweepers, with rotary brooms and rakes, crablike all-purpose handling robots, a couple of vacuum-cleaning robots, each with a flexible funnel-tipped proboscis and a bulging dust-sack. One tiling, a sort of special job designed to get into otherwise inaccessible places, had a twenty-foot, many-jointed, claw-tipped arm in front. It passed by and slightly over the tower, saw Clyde Nichols, and swooped toward him. With a howl, Nichols dived under one of the large machines between two production lines. A pistol went off a couple of times. That would be Jerry Rivas. Nobody else bothered with a gun on Koshchei, but he carried one as some people carry umbrellas, whether he expected to need it or not and because he would feel lost without it.

That he took in at one glance. Then he was looking at the control panels. The switches and buttons were all marked for machine-control in different steps of power-unit production. That was all for the big stuff, powered centrally. There weren't any controls for lifters or conveyers or other mobile equipment. Evidently they were handled out in the shop, from mobile control-vehicles. He did find, on the communication-screen panel, a lot of things that had been left on. He snapped them off, one after another, snapping them on when a screen went dark. There were fifteen or twenty robots, some rather large, in the air or moving on the floor by now.

"We can't do anything here," he told Anse. "These are the shop-cleaning robots. They were the last things used here when the place closed down, and the two supervisors were probably controlled from a vehicle, and it's anybody's guess where that is now. When you threw that switch, it sent out an impulse that activated them. They're running their instruction-tapes, and putting the others through all their tricks."

Three more shots went off. Jerry Rivas was shouting: "Hey, whattaya know! I killed one of the buggers!"

There were any number of ways in which a work-robot could be shot out of commission with a pistol. All of them would be by the purest of pure luck. The next time we go into a place like this, Conn thought, we take a couple of bazookas along.

"Turn everything off and let's go. See what we can do outside."

Anse put on his flashlight and pulled the switch. They got into the lift and rode down, going outside. As soon as they emerged, they saw a rectangular object fifteen feet long settle over their aircar, let down half a dozen clawed arms, and pick it up, flying away with it. It had taped instructions to remove anything that didn't belong in the aisleway; it probably asked the supervisor about the aircar, and the supervisor didn't return an inhibitory signal, so it went ahead. Conn and Anse both shouted at it, knowing perfectly well that shouting was futile. Then they were running for their lives with one of the crablike all-purpose jobs after them. They dived under the slightly raised bed of a long belt-conveyer and crawled. Jerry Rivas fired another shot, somewhere.

The robots themselves were having troubles. They had done all the work they were supposed to do; now the supervisors were insisting that they do it over again. Uncomplainingly, they swept and raked and vacuum-cleaned where they had vacuum-cleaned and raked and swept forty years ago. The scrap-pickers, having picked all the scrap, were going over the same places and finding nothing, and then getting deflected and gathering a lot of things not definable as scrap, and then circling around, darting away from one another in obedience to their radar-operated evasion-systems, and trying to get to the outside scrap pile, and finding that the doors wouldn't open because the door openers weren't turned on, and finally dumping what they were carrying when the supervisors gave them no instructions.

One of them seemed to have dumped something close to where Clyde Nichols was hiding; if his language had been a little stronger, it would have burned out Conn's radio. Their own immediate vicinity being for the moment clear of flying robots, Conn and Anse rolled from under the conveyer and legged it between the two production lines. Immediately, three of the crablike all-purpose handling-robots saw them, if that was the word for it, and came dashing for them, followed by a thing that was mostly dump-lifter; it was banging its bin-lid up and down angrily. About fifty yards ahead, Jerry Rivas stepped from behind a machine and fired; one of the handling-robots flashed green from underneath, went off contragravity, and came down with a crash. Immediately, like wolves on a wounded companion, the other two pounced upon it, dragging and pulling against each other. That was a hunk of junk; their orders were to remove it.

The mobile trash-bin went zooming up to the ceiling, reversed within twenty feet of it and came circling back to the ground, to go zooming up again. It had gone crazy, literally. It had been getting too many contradictory orders from its supervisor, and its circuits were overloaded and its relays jammed. Rats in mazes and human-type people in financial difficulties go psychotic in very much the same way.

The two surviving all-purpose robots were also headed for a padded repair shop. They had come close enough to each other to activate their anticollision safeties. Immediately, they flew apart. Then their order to pick up that big piece of junk took over, and they started forward again, to be bounced apart as soon as they were within five feet of one another. If left alone, their power units would run down in a year or so; until then, they would keep on trying.

Soulless intelligences, indeed! Then it occurred to him that for the past however-long-it-had-been he hadn't heard from Mohammed Matsui. He jiggled his radio.

"Ham, where are you? Are you still alive?"

"I'm back at the power plant," Matsui said exasperatedly. "There's a big thing circling around here; every time I stick my head out, he makes a dive at me. I didn't know robots would attack people."

"They don't. He just thinks you're some more trash he's been told to gather up."

Matsui was indignant. Conn laughed.

"On the level, Ham. He has photoelectric vision, and a picture of what that aisle is supposed to look like. When you get out in it, he knows you don't belong there and tries to grab you."

"Hey, there's a lot of junk in here in a couple of baskets at the converter. Say I chuck one out to him; what would he do?"

"Grab it and take it away, like he's taped to do."

"Okay; wait a minute."

They couldn't see the archway to the power plant, or even the robot that had Matsui penned up, but after a few minutes they saw it soaring away, clutching a big wire basket full of broken boxes and other rubbish. It headed for the mutually repelling swarm of robots around the door that wouldn't open for them. Conn and Anse and Jerry ran toward the rear, joined by Clyde Nichols, who popped up from behind a pile of spools of electric wire. They made it just before the coffin-shaped thing that had carried off the aircar came over to investigate.

"You want to be careful back there," Matsui told them, as they started toward the temporary safety of the power plant. "All the reactor-repair robots are there; don't get them on the warpath next."

Of course! There were always repair-robots at a power plant, to go into places no human could enter and live. Behind the collapsium shielding, they wouldn't have been activated.

"Let's have a look at them. What kind?"

"Standard reactor-servicers; the same we used at the administration center."

Matsui opened the door, and they went into the power plant. Conn and Matsui put on the service-power and activated the two supervisors; they, in turn, activated their workers. It was tricky work getting them all outside the collapsium-walled power-plant area; each worker had to be passed through by the supervisor inside, under Matsui's control. Because of the close quarters at which they worked inside the reactor and the converter, they weren't fitted with anticollision repulsors, and, working under close human supervision, they all had audiovisual pickups. It took some time to get adequate screens set up outside the collapsium.

Finally, they were ready. Their two supervisors went up to the ceiling, one controlled by Conn and the other by Matsui. The larger, egg-shaped shop-labor supervisors were still moving in irregular orbits; those of the workers still able to receive commands were trying to obey them, and the rest were jammed in a swarm at the other end.

First one, and then the other of the labor-boss robots were captured. They were by now at the end of what might, loosely, be called their wits. They weren't used to operating without orders, and had been sending out commands largely at random. Now they came to a stop, and then began moving in tight, guided circles; one by one, the worker robots still able to heed them were brought to ground and turned off. That left the swarm at the door. The worker-robots under direct control of the power-plant supervisors went after them, grappling them and hauling them down to where Anse and Jerry Rivas and Captain Nichols could turn them off manually.

The aircar was a hopeless wreck, but its radio was still functioning. Conn called Charley Gatworth, who called a gang under Gomez, working not far away; they came with another car.

It took all the next day for a gang of six of them to get the place straightened up. Neither Conn nor Gomez, who was a roboticist himself, would trust any of the workers or the two supervisors; their experiences out of control had rendered them unreliable. They took out their power units and left them to be torn down and repaired later. Other robots were brought in to replace them. When they were through, the power-unit cartridge plant was ready for operation.

Jerry Rivas wanted to start production immediately.

"We'll have to go back to Poictesme pretty soon," he said. "We don't want to go back empty. Well, I know that no matter what we dug up, and what we could sell or couldn't sell, there's always a market for power-unit cartridges. Electric-light units, household-appliance units, aircar and airboat units, any size at all. We run that plant at full capacity for a few days and we can load the Harriett Barne full, and I'll bet the whole cargo will be sold in a week after we get in."

The Harriet Barne settled comfortably at the dock, the bunting-swathed tugs lifting away from her. They had the outside sound pickups turned as low as possible, and still the noise was deafening. The spaceport was jammed, people on the ground and contragravity vehicles swarming above, with police cars vainly trying to keep them in order. All the bands in Storisende seemed to have been combined; they were blaring the "Planetary Hymn";

Genji Gartner's body lies a-moldering in the tomb,
But his soul goes marching on!

When they opened the airlock, there was a hastily improvised ceremonial barge, actually a farm-scow completely draped in red and white, the Planetary colors. They all stopped, briefly, as they came out, to enjoy the novelty of
