"You’ll catch on fast," the elderly and worn supervisor told him. "Just go through this list and kind of get acquainted with it. Your truck will be along in a moment."
The list was in reality a thick volume of lists, of all kinds of waste materials. Apparently everything in the world that could be discarded was in the book. And each item was followed by a key number. These numbers ran from one to thirteen and seemed to be the entire purpose of the volume. While Carl was puzzling over their meaning there was the sudden roar of a heavy motor. A giant robot-operated truck pulled up the ramp and ground to a stop near them.
"Garbage truck," the supervisor said wearily. "She’s all yours."
Carl had always known there were garbage trucks, but of course he had never seen one. It was a bulky, shining cylinder over twenty metres long. A robot driver was built into the cab. Thirty other robots stood on foot-steps along the sides.
The supervisor led the way to the rear of the truck and pointed to the gaping mouth of the receiving bin.
"Robots pick up the garbage and junk and load it in there," he said. "Then they press one of these here thirteen buttons keying whatever they have dumped into one of the thirteen bins inside the truck. They’re just plain lifting robots and not too brainy, but good enough to recognize most things they pick up. But not all the time. That’s where you come in, riding along right there."
The grimy thumb was now aiming at a transparent-walled cubicle that also projected from the back of the truck. There was a padded seat inside, facing a shelf set with thirteen buttons.
"You sit there, just as cozy as a bug in a rug I might say, ready to do your duty at any given moment. Which is whenever one of the robots finds something it can’t identify straight off. So it puts whatever it is into the hopper outside your window. You give it a good look, check the list for the proper category if you’re not sure, then press the right button and in she goes. It may sound difficult at first, but you’ll soon catch onto the ropes."
"Oh, it sounds complicated all right," Carl said, with a dull feeling in his gut as he climbed into his turret, "But I’ll try and get used to it."
The weight of his body closed a hidden switch in the chair, and the truck growled forward. Carl scowled down unhappily at the roadway streaming out slowly from behind the wheels, as he rode into the darkness, sitting in his transparent boil on the back-side of the truck.
It was dull beyond imagining. The garbage truck followed a programmed route that led through the commercial and freightways of the city. There were few other trucks moving at that hour of the night, and they were all robot driven. Carl saw no other human being. He was mug as a bug. A human flea being whirled around inside the complex machine of the city. Every few minutes the truck would stop, the robots clatter off, then return with their loads. The containers dumped, the robots leaped back to their foot-plates, and the truck was off once more.
An hour passed before he had his first decision to make. A robot stopped in mid-dump, ground its gears a moment, then dropped a dead cat into Carl’s hopper. Carl stared at it with horror. The cat stared back with wide, sightless eyes, its lips drawn back in a fierce grin. It was the first corpse Carl had ever seen. Something heavy had dropped on the cat, reducing the lower part of its body to paper-thinness. With an effort he wrenched his eyes away and jerked the book open.
Castings… Cast Iron…. Cats (dead)… Very, very much dead. There was the bin number. Nine. One bin per life. After the ninth life-the ninth bin. He didn’t find the thought very funny. A fierce jab at button 9 and the cat whisked from sight with a last flourish of its paw. He repressed the sudden desire to wave back.
After the cat boredom set in with a vengeance. Hours dragged slowly by and still his hopper was empty. The truck rumbled forward and stopped. Forward and stop. The motion lulled him and he was tired. He leaned forward and laid his head gently on the list of varieties of garbage, his eyes closed.
"Sleeping is forbidden while at work. This is warning number one."
The hatefully familiar voice blasted from behind his head and he started with surprise. He hadn’t noticed the pickup and speaker next to the door. Even here, riding a garbage truck to eternity, the machine watched him. Bitter anger kept him awake for the duration of the round.
Days came and went after that in a gray monotony, the large calendar on the wall of his room ticking them off one by one. But not fast enough. It now read 19 years, 322 days, 8 hours, 16 minutes. Not fast enough. There was no more interest in his life. As a sentenced man there were very few things he could do in his free time. All forms of entertainment were closed to him. He could gain admittance — through a side door — to only a certain section of the library. After one futile trip there, pawing through the inspirational texts and moral histories, he never returned.
Each night he went to work. After returning he slept as long as he could. After that he just lay on his bed, smoking his tiny allotment of cigarettes, and listening to the seconds being ticked off his sentence.
Carl tried to convince himself that he could stand twenty years of this kind of existence. But a growing knot of tension in his stomach told him differently.
This was before the accident. The accident changed everything.
A night like any other night. The garbage truck stopped at an industrial site and the robots scuffled out for their loads. Nearby was a cross-country tanker, taking on some liquid through a flexible hose. Carl gave it bored notice only because there was a human driver in the cab of the truck. That meant the cargo was dangerous in some way, robot drivers being forbidden by law from handling certain loads. He idly noticed the driver open the door and start to step out. When the man was halfway out he remembered something, turned back and reached for it
For a short moment the driver brushed against the starter button. The truck was in gear and lurched forward a few feet. The man quickly pulled away — but it was too late.
The movement had been enough to put a strain on the hose. It stretched — the supporting arm bent — then it broke free from the truck at the coupling. The hose whipped back and forth, spraying greenish liquid over the truck and the cab, before an automatic cut-out turned off the flow.
This had taken only an instant. The driver turned back and stared with horror-widened eyes at the fluid dripping over the truck’s hood. It was steaming slightly.
With a swooshing roar it burst into fire, and the entire front of the truck was covered with flame. The driver Invisible behind the burning curtain.
Before being sentenced Carl had always worked with robot assistance. He knew what to say and how to say it to get instant obedience. Bursting from his cubicle he slapped one of the garbage robots on its metal shoulder and shouted an order. The robot dropped a can it was emptying and ran at full speed for the truck, diving into the flames.
More important than the driver, was the open port on top of the truck. If the flames should reach it the entire truck would go up — showering the street with burning liquid.
Swathed in flame, the robot climbed the ladder on the truck’s side. One burning hand reached up and flipped the self-sealing lid shut. The robot started back down through the flames, but stopped suddenly as the fierce heat burned at its controls. For a few seconds it vibrated rapidly like a man in pain, then collapsed. Destroyed.
Carl was running towards the truck himself, guiding two more of his robots. The flames still wrapped the cab, seeping in through the partly open door. Thin screams of pain came from inside. Under Carl’s directions one robot pulled the door open and the other dived in. Bent double, protecting the man’s body with its own, the robot pulled the driver out. The flames had charred his legs to shapeless masses and his clothes were on fire. Carl beat out the flames with his hands as the robot dragged the driver clear.
