Relegar squealed. His two eyes almost exploded in a rage of red. He wasn't permanently injured--he would grow a new leg--but he was furious because he dared not come close to the shield. The radiation would paralyze him within a couple of seconds. Grant saw his body sag a little on the corner where the leg had been, and then he had one of those flashes of intuition that every being had to have, to live long in the swamp. He knew how to win this fight. He trained the heat-gun on the second leg on the same side and pressed the trigger. That leg burned in two and Relegar's body sagged still more. Grant started on the third one. A feeling of triumph was growing in him. Then Relegar charged. Grant hadn't expected that. There was little he could do but hold the shield frantically before him to try to ward off the fangs and the mandibles. He had had no idea that the Uranian's body was so heavy. It seemed to Grant the thing must weigh three or four hundred pounds. It thundered into him and knocked him over as if he had been a straw. The heavy hoofs galloped over him. He was surprised, but he rolled on over and came to his feet, shooting. He got the fourth and fifth legs this time. Relegar's body sagged considerably, but the spider, his entire body turning red with rage, spun around and charged again. This time the great mouth was open, the fangs ready, and the mandibles were extended. Grant left himself open until he could feel the spider's fetid breath in his face, then he flung out his shield. The sharp fangs struck it. Relegar turned into a tornado of fury for perhaps a second, trying to shake the skin from his teeth. But it was too late. The skin came loose, but the radiation had paralyzed the spider. He sank feebly to the ground with the shield under him. His eyes glared with unutterable malignant hate, but that was all. His muscles were impotent. Grant stood a few feet away, getting his breath, feeling the trip-hammer in his temple slow down to normal. Then he aimed. The sixth, seventh, and eighth legs burned off. He put the pistol in its holster. "I'm not going to try to kill you," he said. "I suppose that's impossible anyway, short of cutting you up into small pieces, and I don't relish that idea. But I'll leave you the snake-skin. It will have passed the peak of its radioactivity by tomorrow and you can start back for The Pass. But you won't go back very fast. You've got legs on only one side. It's going to be slow navigating, especially on water. In fact, I think maybe you'll have to wait until you grow some new legs." He patted his pockets filled with half a million dollars' worth of echindul stones. "Long before that I'll be in Aphrodite depositing my stones at the First Interplanetary Bank."
