<passage>:
I The girl with the Slider egg glittering in her hair watched the bailiff lead Asa Graybar out of the courtroom. He recognized her as Tom Dorr, Hazeltyne's general manager, was her escort. Asa felt 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 laboratory. The older man stared at Asa coldly as he was led out of to be a muck man, Jumpy. I'm going out to Jordan's Planet and hunt Slider eggs." "Smuggling? It won't work." Asa didn't answer. The Hazeltyne company had gone after him because he had been working on a method of keeping Slider eggs alive. The 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. muck men on Jordan's Planet." choose Jordan's Planet. Asa frowned in apparent consideration of the 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. Sometimes he could hear voices in the passageway outside, and once 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 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 Electrical instruments picked up static discharges from the egg, but the phenomenon remained a mystery. 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 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 the egg calling its momma. They sparkle like a million diamonds when Asa Graybar kept his normal form on Jordan's Planet just long enough to When he finally awoke he felt well rested and very comfortable. But for a long time he was afraid to open his eyes. "Come on, Graybar," said a deep, booming voice. "Let's test our wings." It was not Kershaw's voice, but it had to be Kershaw. Asa opened his eyes. in two leaps. Attached to a harness across his shoulders and chest were a gun and a long knife. "Names?" he growled. He was a foot taller than Graybar and big everywhere in proportion. "Kershaw. I'm back, Furston." "I'm Graybar." "Kershaw again? Just start in where you left off, sucker. Come on, you." He pointed to Asa and leaped to the open portion of the courtyard. "Do what he says," Kershaw whispered to Graybar. "He's sort of a trusty 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 Next morning Furston passed out guns, knives, radios, and pouches to carry any eggs the muck men found. He gave each man a compass and assigned the sectors to be worked during the day. Finally he called Graybar aside. "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." Furston sent Graybar and Kershaw out together so that the veteran could yards in diameter where the weeds had been torn out and lay rotting in the muck. "We're in luck," he said as Asa skidded to a stop at his side. "An egg was laid somewhere here within the last week. These places are hard to spot when the new weeds start growing." 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 about the operation was wrong. earphones and he thought of what Kershaw had said, that the scintillation of an egg was an effect of its calls to a mother Slider and Graybar, sector eight, five miles out. Hurry!" "Graybar?" asked a voice in his earphone. "What's up?" "We've got an egg but a Slider wants it back." "On the way." Asa hopped back to the clearing. Kershaw must have been bowled over by the Slider's first rush, for he was trying to hop on one leg as if the other had been broken. The egg lay flickering on top of the mud where Slider would be on top of him before he could escape. As he landed he 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 where it rested on the mud. He scooped a hole in the muck and buried the egg. "Just in case there are any more Sliders around," he explained. "Makes no difference," said Kershaw, pointing upward. "Here comes the and leaned out. "I see you took care of the Slider," he said. "Hand over the egg." "Kershaw has a broken leg," Asa said. "I'll help him in and then I'll get the egg." While Kershaw grabbed the door frame to help pull himself into the helicopter, Asa got under his companion's belly and lifted him by the cabin was crowded. "Are you going to have room for me too?" he asked. "Not this trip," Dorr answered. "Now give me the egg." Asa didn't hesitate. "The egg stays with me," he said softly. "You do what I tell you, mucker," said Dorr. "Nope. I want to make sure you come back." Asa turned his head to Dorr stared at him with narrowed eyes. Suddenly he smiled in a way that worried Asa. "Whatever you say, Graybar," Dorr said. He turned to the controls. In minutes, allowing time for Kershaw to be taken out at the settlement. 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. Asa pulled down the mouthpiece of his radio. "This is Graybar, calling the helicopter," he said. "When are you coming?" There was no answer except the hum of carrier wave. If he tried to carry the egg back, Asa knew, Sliders would attack him all along the way. A man had no chance of getting five miles with an egg by himself. He could leave the egg here, of course. Even so he would be lucky if he got back, following a hazy compass course from which he and Kershaw had certainly deviated on their outward trip. What was the night like on Jordan's Planet? Maybe Sliders slept at night. If he could stay awake, and if he didn't faint from hunger in this strange new body, and if the Sliders left him alone.... carcass of the dead Slider and took shelter behind it. to Jordan's Planet on a fancy tour.
