"I'll shoot the animal before it reaches you." Ri gulped for air. "But ... if there should be more than one?" killed a farn beast before I Ri shrugged hopelessly. Mia said, "I don't think he even saw a blast area over here. I think he Ri cleared his throat nervously. "Maybe you're right." "It's the Hunting Club he don't like." "I wish to God I'd never heard of a farn beast," Ri said. "At least, then, I wouldn't be one of his guides. Why didn't he hire somebody else?" Shortly they were inside of the scrub forest, safe from sight. "Let's wait here," Mia said. "No, we better go on. He may have sent a spy in." "You will scream," Extrone instructed. With his rifle, he pointed across the water hole. "The farn beast will come from this direction, I They pushed on, being careful to blaze the trees, because they were not professional guides. imagine." forest for many minutes. "Without guns, we don't want to get near enough for the farn beast to charge us." "We don't want to get too near," Ri said after toiling through the They stopped. The forest was dense, the vines clinging. "He'll want the bearers to hack a path for him," Mia said. "But we go Ri was almost slobbering in fear. he brought." "The ones who discovered the farn beasts in the first place?" Mia asked. "You think it's their blast?" "So?" Ri said. "But who are they?" It was Mia's turn to shrug. "Whoever they were, they couldn't have been hunters. They'd have kept the secret better." "We didn't do so damned well." A farn beast coughed, far in the matted forest. Extrone laughed nervously. "He must have heard." "We didn't have a chance," Mia objected. "Everybody and his brother had heard the rumor that farn beasts were somewhere around here. It wasn't our fault Extrone found out." "I wish we hadn't shot our guide, then. I wish he was here instead of "We're lucky to rouse one so fast," Lin said. Extrone we'd hunted this area." "I didn't think a Club pilot would do that." "After Extrone said he'd hunt farn beasts, even if it meant going to Mia shook perspiration out of his eyes. "We should have shot our pilot, the alien system? Listen, you don't know.... Wait a minute." "Listen," Mia said in a hoarse whisper. "I just thought. Listen. To . And besides, why would he want to do that? It wouldn't do any good to shoot us. Too many people already know about the farn beasts. You said that yourself." Mia said, "I hope you're right." They stood side by side, studying the Ri, below, whimpered childishly and began to retreat toward the tether "There's a lot of satisfaction in fooling them, too," Extrone said. "Making them come to your bait, where you can get at them." He "There may be a pass," Mia said, pushing a vine away. "Killing?" "Hunting," Extrone repeated harshly. The farn beast coughed. Another answered. They were very near, and there was a noise of crackling underbrush. "He's good bait," Extrone said. "He's fat enough and he knows how to scream good." Ri had stopped screaming The farn beast, its tiny eyes red with hate, stepped out on the bank, swinging its head wildly, its nostrils flaring in anger. It coughed. Its mate appeared beside it. Their tails thrashed against the scrubs The lead farn beast sighted Ri. It lowered its head. "Look!" Extrone cried excitedly. "Here it comes!" Ri began to scream again. waited, frozen, his eyes staring at the farn beast in fascination. The farn beast plunged into the water, which was shallow, and, throwing a sheet of it to either side, headed across toward Ri. "Watch! Watch!" Extrone cried gleefully. Extrone plucked at his right ear lobe, half closing his eyes. "You'll lose a fleet before you'll dare let anything happen to me, gentlemen. I'm quite safe here, I think." "Sir?" Ri said, hurrying toward him in the gathering darkness. "Eh?" Extrone said, turning, startled. "Oh, you. Well?" "We ... located signs of the farn beast, sir. To the east." Extrone nodded. After a moment he said, "You killed one, I believe, on your Ri obeyed the order. electric from a portable dynamo. Extrone flipped it on. He crossed to the bed, sat down. "You were, I believe, the first ever to kill a farn beast?" he said. "I.... No, sir. There must have been previous hunters, sir." Extrone narrowed his eyes. "I see by your eyes that you are Ri looked away from his face. "Perhaps I'm envious of your reputation as a hunter. You see, I have never killed a farn beast. In fact, I haven't seen a farn beast." Ri glanced nervously around the tent, his sharp eyes avoiding Extrone's glittering ones. "Few people have seen them, sir." "I meant in our system, sir." "Of course you did," Extrone said, lazily tracing the crease of his sleeve with his forefinger. "I imagine these are the only farn beasts in our system." Ri waited uneasily, not answering. "... I'm flattered, sir." "Of course," Extrone said. "But you should have spoken to me about it, when you discovered the farn beast in our own system." "I realize that, sir. That is, I had intended at the first opportunity, sir...." Mia nodded. "It makes you think," Mia added. He twitched. "I'm afraid. I'm afraid "No," Ri said stubbornly. "Listen," Mia pleaded. "No," Ri said. "Even if we tried to tell them, they wouldn't listen. Ri whined nervously. "No?" Mia challenged. "Couldn't we? Not today, but what about tomorrow? Lin waited. "Now I can spit on them, which pleases me." "The farn beasts are dangerous, sir," Lin said. "Eh? Oh, yes. Those. What did the manual say about them?" "I believe they're carnivorous, sir." all afraid of you." "The farn beasts, according to the manual...." "You are very insistent on one subject." "... It's the only thing I know anything about. The farn beast, as I was saying, sir, is the particular enemy of men. Or if you like, of aliens. Sir." "Look," Extrone said. "If that's the case, why do we bother tracking them? Why not make them come to us?" "They're too unpredictable. It wouldn't be safe. I'd rather have surprise on our side." Extrone was seated, petting his rifle. Extrone nodded genially. "The farn beast hunter, eh?" "Yes, sir."
