HUNT the HUNTER "Pretty frightening?" Still, endless, hopeless, monotonous, Ri screamed. way to lure dangerous alien animals ... bait." "No!" "Oh, come now. When the farn beast hears you scream—you can scream, Extrone raised his eyebrows. This time, the coughing roar was more distant, but distinct. "It is!" Ri said. "It's a farn beast, all right!" Extrone smiled, almost pointed teeth showing through the beard. "I'm glad we won't have to cross the ridge." were trembling. "It's not me you want to do this to. It's Mia, sir. He killed a farn beast before I did, sir. And last night—last And to Mia, "God almighty, he was getting mad." He ran a hand under his collar. "It's a good thing that farn beast sounded off when it did. I'd hate to think of making him climb that ridge." 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?" of a scaling tree. "You will scream," Extrone instructed. With his rifle, he pointed across the water hole. "The farn beast will come from this direction, I imagine." "We don't want to get too near," Ri said after toiling through the forest for many minutes. "Without guns, we don't want to get near enough for the farn beast to charge us." 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?" "We didn't do so damned well." A farn beast coughed, far in the matted forest. heard the rumor that farn beasts were somewhere around here. It wasn't our fault Extrone found out." Extrone laughed nervously. "He must have heard." "We didn't have a chance," Mia objected. "Everybody and his brother had "We're lucky to rouse one so fast," Lin said. "I wish we hadn't shot our guide, then. I wish he was here instead of 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 the alien system? Listen, you don't know.... Wait a minute." to kill it?" The farn beast coughed again nearer. . 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 "The breeze dies down." "It's screwy. I didn't think farn beasts had this wide a range. There must be a lot of them, to be on both sides of the ridge like this." "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 The forest sprang apart. Extrone bent forward, the gun still across his lap. 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. Still Extrone did not lift his blast rifle. He was laughing. Lin 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. "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 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." that the aliens hunt them quite extensively ... on some of their "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...." 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." "An alien manual. That's ludicrous, too. That we have the only information on our newly discovered fauna from an alien manual—and, of course, two businessmen." "They have very long, sharp fangs, and, when enraged, are capable of tearing a man—" "An alien?" Extrone corrected. 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." for farn beasts, and ahead, beyond the cutters, Lin flittered among the "I don't want to listen to your gabbling when I'm hunting!" Extrone The farn beast, somewhere beyond a ragged clump of bushes, coughed. Extrone clenched the blast rifle convulsively. The farn beast coughed again, more distant this time. "Look," Extrone said. "If that's the case, why do we bother tracking ineffectual. He followed Lin beyond an outcropping of shale to where Extrone was seated, petting his rifle. Extrone nodded genially. "The farn beast hunter, eh?" "Yes, sir." Extrone drummed his fingers on the stock of the blast rifle. "Tell me "Well, sir, they're ... uh...."
