The egg was flashing with a mad radiance, like a thousand diamonds being splintered under a brilliant sun. Static crackled in Asa's 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 for help. Asa looked around. "Jump!" he shouted. At the edge of the clearing a segmented length of greenish black scales, some two feet thick and six feet high, had reared up out of the weeds. The top segment was almost all mouth, already opened to show row upon row of teeth. Before Asa could draw his gun the Slider lowered its head to the ground, dug two front flippers into the mud and shot forward. Asa leaped with all his strength, sailing far out of the clearing. While he was still in the air he snapped the mouthpiece of his radio down from where it was hinged over his head. As he landed he turned instantly, his gun in his hand. "Calling the 'copter!" he spoke rapidly into the mouthpiece. "Kershaw 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 Kershaw had dropped it. The Slider, eight flippers on each side working madly, was twisting its thirty feet of wormlike body around for another charge. Aiming hastily, Asa fired a rocket at the monster's middle segment. The rocket smashed through hard scales and exploded in a fountain of gray flesh. The Slider writhed, coating its wound in mud, and twisted toward Asa. He leaped to one side, firing from the air and missing, and saw the Slider turn toward the patch of weeds where he would land. His legs were tensed to leap again the moment he hit the mud, but he saw the Slider would be on top of him before he could escape. As he landed he thrust his gun forward almost into the mouth of the creature and fired again. Even as he was knocked aside into the muck, Asa's body was showered 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. Asa took a deep breath and looked around. "Kershaw!" he called. "Where are you?" "Over here." Kershaw stood briefly above the weeds and fell back again. Asa leaped over to him. "Thanks," Kershaw said. "Muck men stick together. You'll make a good one. I wouldn't have had a chance. My leg's busted." "The helicopter ought to be here pretty soon," Asa said. He looked over at the dead Slider and shook his head. "Tell me, what are the odds on 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."
