<passage>:
The work wasn't hard, but there were some sacrifices. You had to give up hope and freedom—and being human! I The girl with the Slider egg glittering in her hair watched the certain, without proof, that Dorr was the man who had framed him for the charge of grand theft by secreting a fresh Slider egg in his Jumpy, Asa's cellmate, took one look at his face as he was put back "Five or one." "Take the five," Jumpy advised. "Learn basket-weaving in a nice air-conditioned rehab clinic. A year on a changeling deal will seem a Slider eggs." he had been working on a method of keeping Slider eggs alive. The Hazeltyne company would be happy to see him mark time for five years Planet, with his physiology adapted to the environment of that wretched world, he could study the eggs under conditions no laboratory could senescence could be staved off, however, any man could have bulging biceps and a pencil waist, if he could pay for the treatment. Until the medical associations declared such treatments unethical there Unfortunately for planetary development companies, hardly anyone wanted to become a changeling. High pay lured few. So a law was passed 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. alternatives. "What's the pay range?" he asked. "Ten dollars a day on Caesar's Moon. Fifteen on New Arcady or Von Neumann Two. Twenty-five on Jordan's." mud while they hunt Slider eggs. But don't your conversions make 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 spaceships nor worked in the dome settlements on harsher worlds, he decided it was his imagination. He might have been dead cargo for all he learned about space travel. Nevertheless his time was not wasted. He had as a companion, or 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 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 flashes maybe four times a day. So I stole a new one and got caught." Asa had held a Slider egg in his hand as he gazed into it. He could Hardly anyone faced with the beauty of a Slider's egg bothered to question its workings. For a few expectant moments there would be only 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 made him wealthy at the expense of the Hazeltyne monopoly. "You know what I think?" Kershaw asked. "I think those flashes are you scoop one out of the muck, and right away a Slider always comes Sliders?" When the Slider catches you, you leap up while it buries its jaws in pounding to keep his blood circulating on this massive world, but the doctor had apparently learned to make allowances. to back out of becoming a changeling, that he was on his way to the conversion tank right now. so that his arms dangled to the ground. The arms were as thick around as an ordinary man's legs. The hands had become efficient scoops, with and muscle coordination was perfect. He found himself leaping as high as Kershaw's head. "That's the way," Kershaw said approvingly. "Now get this on and we'll Furston laughed. "That's to remind you you're still a man," Furston said, grinning. Asa turned without a word and hopped feebly away from Furston. He an observation tower on the roof. He leaped twenty feet into the air for a closer look. Gazing at him with repugnance, after witnessing the end of his session The girl's presence merely puzzled Asa, but Dorr's being here worried 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 two were doing out here. "The girl will inherit this racket some day, won't she?" asked one of the others. "She wants to see what kind of suckers are making her rich." "Maybe that guy Dorr brought her along to show her what a big wheel he is," said one of the others. "Just hope he doesn't take over the "In case you don't like it here," Furston said, "you can get a week knocked off your sentence for every egg you bring in. Now get out there and work that muck." 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 watch. "A big one," Kershaw said. He held it, still smeared with traces of A SLIDER EGG "We've got an egg but a Slider wants it back." the Slider's first rush, for he was trying to hop on one leg as if the the Slider turn toward the patch of weeds where he would land. His legs Slider would be on top of him before he could escape. As he landed he getting killed doing this?" "Last time I was here there was about one mucker killed for every six eggs brought out. Of course you're not supposed to stand there admiring the eggs like I did while a Slider comes up on you." Asa hopped over to the egg, which was still full of a dancing radiance "Just in case there are any more Sliders around," he explained. "I see you took care of the Slider," he said. "Hand over the egg." "Not this trip," Dorr answered. "Now give me the egg." After an hour passed Asa began to worry. He was sure Dorr would return for the egg. Finally he realized that Dorr could locate the egg 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. If he tried to carry the egg back, Asa knew, Sliders would attack him back alone to dispose of him without any witnesses? Asa leaped for the carcass of the dead Slider and took shelter behind it. hover, thumped down upon the mud and slid forward. As Asa jumped aside, the landing skids caught against the Slider's body and the helicopter "What happened?" "I made a fool of myself." She made a face back in the direction of the settlement. "Dorr wasn't going to come after you. He said anyone "The Slider you killed would draw them like ants to jam." Asa glanced around quickly to make sure no Sliders had already come. He eyed the helicopter with distaste at the thought of what a flimsy fort it would make. and we started arguing. I lost my temper. He thought he had brought me to Jordan's Planet on a fancy tour. I told him the real reason I was here was to check up for my father on the way he was running things and there seemed to be a lot wrong. So he told me very politely I could run things to suit myself and he walked off." She shrugged, as if to indicate that she had made a mess of things. Asa tugged at the body of the Slider until he got it off the skids of
