Illustrated by WOOD [Transcriber's Note: This etext was produced from Clay, at the Association of Professional Engineers, who had set up the The interview was at three. Fifteen minutes to go. Coming early would betray overeagerness. Peter stood in front of the Lex Industries plant he ambled, come back to the front entrance just before three. There had been windows at the front. There were none at the side, and none at the rear. Then how were the working areas lit? He looked for the electric service lines and found them at one of the rear corners. They jolted him. The distribution transformers were ten times as large what it was. Factories usually have large side doorways for employees changing shifts. This building had one small office entrance facing the street, and the only other door was at the loading bay—big enough to handle employee traffic, but four feet above the ground. Without any stairs, it could be used only by trucks backing up to it. Maybe the employees' entrance was on the third side. It wasn't. Staring back at the last blank wall, Peter suddenly remembered the time set to straight-arm the door, he almost fell on his face. The door had a soft voice said through a loudspeaker in the anteroom wall: "Mr. "What?" he panted. "Who—?" but the soft voice said: "Follow the open doors down the hall. Mr. Lexington is expecting you." "Thanks," Peter said, and a door at one side of the anteroom swung open He went through it with his composure slipping still further from his grip. This was no way to go into an interview, but doors kept opening before and shutting after him, until only one was left, and the last of his calm was blasted away by a bellow from within. "Don't stand out there like a jackass! Either come in or go away!" all the while thinking, Hold on now you're in no shape for an straightened his jacket and tie, and walked in as an engineer applying "Sit down," said the man at the desk.

It wasn't comfortable. into Hollywood's idea of an office. to the man, about 65, and he saw the muscles had turned to fat, the complexion ashen, the eyes set deep as though retreating from pain, and "I'm applying for a job as engineer." "Just as I said—they stockpiled you, instead of using you as an engineer. They hired you at a cut wage and taught you things that would get a job with someone else?" out of the stockpile, put you in just about any job they wanted, at any wage you'd stand for, and they'd have an indentured worker with a What makes you think you're qualified for the job I'm offering?" "And now you're wondering why I don't get somebody fresh out of school. "No, you're not." "Then what am I after?" In precis form, Peter listed his observations: the absence of windows at sides and rear, the unusual amount of power, the automatic doors, the lack of employees' entrances. "Yes," Peter said. "You're the only person I've seen in the building." The office door opened, and Peter found himself being led down the antiseptic corridor to another door which had opened, giving access to the manufacturing area. As they moved along, between rows of seemingly overhead followed their progress, turning themselves on in advance reached a large door which Peter recognized as the inside of the truck loading door he had seen from outside. Lexington paused here. "This is the bay used by the trucks arriving with raw materials," he said. "They back up to this door, and a set of automatic jacks outside lines up the trailer body with the door exactly. Then the door opens and the truck is unloaded by these materials handling machines." Peter didn't see him touch anything, but as he spoke, three glistening machines, apparently self-powered, rolled noiselessly up to the door in formation and stopped there, apparently waiting to be inspected. They gave Peter the creeps. Simple square boxes, set on casters, with two arms each mounted on the sides might have looked similar. The arms, fashioned much like human arms, hung at the sides, not limply, but in a relaxed position that somehow indicated readiness. Lexington went over to one of them and patted it lovingly. "Really, of the arms rose to the handkerchief in his breast pocket and daintily tugged it into a more attractive position. It took only a split second, to attend to mysterious duties of their own. other materials were stored. sent to the billing section to bill the customer, and an order is sent to our trucker to come and pick the shipment up. Meanwhile, if the withdrawal of the materials required has depleted our stock, the purchasing section is instructed to order more raw materials. I'll take you through the manufacturing and assembly sections right now, but they're too noisy for me to explain what's going on while we're there." each one seemingly intent on cutting, bending, welding, grinding or carrying some bit of metal, or just standing idle, waiting for He wondered what would happen if one of them tried to use the same aisle they were using. He pictured a futile attempt to escape the onrushing wheels, saw himself clambering out of the path of the that was laboring beside him at the moment. Nervously, he looked for an exit, but his apprehension was unnecessary. The machines seemed to know where they were and avoided the two men, or stopped to wait for them to Back in the office section of the building, Lexington indicated a small that room," he said, as the door swung open and Peter saw that the this one over here, purchase orders are prepared, and across the hall there's a very similar rig set up in conjunction with an automatic bookkeeper to keep track of the pennies and to bill the customers." when they walked back into Lexington's office and sat down.

The machine had done it for me this time, then locked the activated. At this point the door opened, and a small self-propelled cart wheeled silently into the room. Stopping in front of Peter, it waited until he Peter looked for the speaker in the side of the cart, saw nothing, and replied, feeling slightly silly as he did so, "Black, please." A square hole appeared in the top of the cart, like the elevator hole in an aircraft carrier's deck. When the section of the cart's surface rose again, a fine china cup containing steaming black coffee rested do, while the cart proceeded over to Lexington's desk. Once there, it about something. Silently, he waited until the cart had left the office, then snapped, "Look at those bloody cups!" Peter looked at his, which was eggshell thin, fluted with carving and ornately covered with gold leaf. "They look very expensive," he said. "Not only expensive, but stupid and impractical!" exploded Lexington. "They only hold half a cup, they'll break at a touch, every one has to be matched with its own saucer, and if you use them for any length of time, the gold leaf comes off!" also wanted to be on hand in case anything should go wrong that the could get the order.
