The work wasn't hard, but there were some sacrifices. You had to give up hope and freedom—and being human!

A year on a changeling deal will seem a lot longer, even if you're lucky enough to live through it." to be a muck man, Jumpy. I'm going out to Jordan's Planet and hunt of so-called social reorientation. But if he could get out to Jordan's Planet, with his physiology adapted to the environment of that wretched world, he could study the eggs under conditions no laboratory could duplicate. He might even be able to cause trouble for Hazeltyne. His only problem would be staying alive for a year. An interview with a doctor from the Conversion Corps was required for all persons who elected changeling status. The law stated that potential changelings must be fully informed of the rights and hazards of altered shape before they signed a release. The requirement held whether or not the individual, like Asa, was already experienced. By the time humanity traveled to the stars, medical biology had made it possible to regenerate damaged or deficient organs of the body. Regeneration was limited only by advanced age. Sometime after a man's two hundredth year his body lost the ability to be coaxed into growing new cells. A fifth set of teeth was usually one's last. As long as temples particularly popular. From regeneration it was a short step to specialized regrowth. The techniques were perfected to adapt humans to the dozen barely habitable worlds man had discovered. Even on Mars, the only planet outside Earth in the solar system where the human anatomy was remotely suitable, a man could work more efficiently with redesigned lungs and temperature controls than he could inside a pressure suit. On more bizarre planets a few light-years away the advantages of changeling bodies were greater. Unfortunately for planetary development companies, hardly anyone permitting a convicted criminal to earn his freedom by putting in one year as a changeling for every five years he would otherwise have had to spend in rehabilitation. asked for Jordan's Planet without some preliminary questions. with the arm structure modified into pseudo-wings or gliding. Then we need spiderinos for Von Neumann Two. If you want the nearest thing we have to Earth, there's Caesar's Moon, where we'd just have to double your tolerance for carbon monoxide and make you a bigger and better gorilla than the natives. Last, of course, there's always a need for muck men on Jordan's Planet." choose Jordan's Planet. Asa frowned in apparent consideration of the Neumann Two. Twenty-five on Jordan's." "Why such a difference? Everyone knows about muck men living in the changeling comfortable in his new environment?" grasshopper despite the double gravity. But we can't make you like the sight of yourself. And we can't guarantee that a Slider won't kill you." "Still," Asa mused aloud, "it would mean a nice bankroll waiting at the end of the year." He leaned forward to fill in the necessary form. Since it was cheaper to transport a normal human than to rig special environments in a spaceship, every planet operated its own conversion chambers. On the space freighter that carried him from Earth Asa Graybar was confined to a small cabin that was opened only for a guard to bring meals and take out dirty dishes. He was still a prisoner. spaceships nor worked in the dome settlements on harsher worlds, he decided it was his imagination. He might have been dead cargo for all cellmate, another convict who had elected conversion to muck man. More important, his companion had done time on Jordan's Planet before and had wanted to return. "It's the Slider eggs," explained Kershaw, the two-time loser. "The ones you see on Earth knock your eyes out, but they've already begun to die. There's nothing like a fresh one. And I'm not the first to go crazy over them. When I was reconverted and got home I had nine thousand dollars waiting for me. That'll buy a two-year-old egg that random, fitful gleamings, and then there would be a wild coruscation of light, dancing from one filament to the next in a frenzy of brilliance. It took about four years for a Slider egg to die. Beauty, rarity and fading value made the eggs a luxury item like nothing the world had ever seen. If Asa had found a means of keeping them alive it would have the mud where you were just standing. You dig your claws in its back and hang on while it rolls around in the mud. Finally, if the 'copter comes—and if they don't shoot off your head by mistake—you live to Asa Graybar kept his normal form on Jordan's Planet just long enough to learn the discomfort of double gravity. He was told he needed another physical examination and was taken right in to a doctor. His heart was pounding to keep his blood circulating on this massive world, but the doctor had apparently learned to make allowances. to lose consciousness. "This is it!" he thought in panic. He felt someone ease him back down onto a wheeled stretcher. Before consciousness faded completely he realized that no one got a chance It would have been more bearable if the head had not retained strong traces of humanity. The nostrils flared wide and the jaws hardly emerged from the neck, but the ears were human ears and the eyes, under go outside." was open to the gray drizzle that fell almost ceaselessly from the sky of Jordan's Planet and turned most of its surface into marsh and mud "That's to remind you you're still a man," Furston said, grinning. "Everything that grows on this planet is poison. So if you got any ideas of hiding out till your term is up, forget 'em. Right here is where you eat." lifted his head to breathe deeply and saw two humans watching him from him. Dorr had tried to get rid of him once and was now in an excellent position to make the riddance permanent. At supper that night, squatting on the ground beside a low table with not at all uncomfortable, and the dripping air caressed their skins like a summer breeze back on Earth. Tiny, slippery creatures skidded and splashed out of their way. Finally Kershaw stopped. His experienced the muck. "We're in luck," he said as Asa skidded to a stop at his side. "An egg big enough to stand in. Each handful of mud had to be squeezed gently before it was thrown away, to make sure it didn't conceal an egg. As he worked, Asa kept thinking what an inefficient system it was. Everything with shreds of alien flesh scattered by the rocket's explosion. Desperately pushing himself to his feet, he saw the long headless body shiver and lie still. worried Asa. "Whatever you say, Graybar," Dorr said. He turned to the controls. In approximately by the body of the dead Slider. Dorr could return for the egg any time with some other muck man to dig for it. What was the night like on Jordan's Planet? Maybe Sliders slept at carcass of the dead Slider and took shelter behind it. No machine-gun blast of rockets came from the helicopter. The big the mud. Asa leaped forward in consternation. Not only was his chance of safe passage back to the settlement wrecked, but now he would have the "They feed at night, you know. And they eat their own kind," she said. to Jordan's Planet on a fancy tour. I told him the real reason I was
