"But we must select a leader!" government over to the Verpp? They seem a level-headed group." "What good would that do? Qornt are Qornt. It seems there's always one among us who's a slave to instinct—and, naturally, we have to follow him." "Why?" "Because that's the way it's done." into Verpp—" "You mean Slun and Zubb—the mild-natured naturalists—will become warmongers like Qorn?" sit around roaring fires and drink and tell lies and then go dashing off to enjoy a brisk affray and some leisurely looting afterward. But we prefer a nice numerical advantage. Not this business of tackling you we have to satisfy our drive to action." "But Mr. Retief is your leader now. He won't let you!" "Only a dead Qornt stays home when Attack day comes. And even if he orders us all to cut our own throats, there are still the other Centers—all with their own leaders. No, gentlemen, the Invasion is definitely on." them." "Those undoubtedly are the most bloodthirsty, aggressive, merciless countenances it has ever been my misfortune to encounter," Magnan said. and faces like that!" "Only Zubb and myself." the beaked face. "Both Zubb and I are Verpp. Naturalists, as it they do nothing but quarrel. A drone caste, actually." "A caste? You mean they're biologically the same as you?" "Not at all! A Verpp wouldn't think of fertilizing a Qornt." There are more at the other Centers, of course."

He spoke "What did he say?" "Poor Zubb. He blames me for his bruises, since it was my idea to gather you as specimens." "You should have known better than to tackle that fierce-looking it's their nest-mending time, you know. The Boog will be busy mating—such a tedious business—and of course the Qornt are tied up with their ceremonial feasting. I'm afraid no one will take any notice of you." "Do you mean to say," Magnan demanded, "that these ferocious Qornt, who openly avow their occupied world—would ignore Terrestrials in their puffed, trotting at Retief's side. "These fellows Zubb and Slun—Oh, they seem affable enough, but how can we be sure we're not being led into a trap?" "We can't." "Nonsense, Slun!" Zubb pushed forward. "I'll escort our guests to Qornt plotting mischief." "Threaten them with violence, Mr Magnan. They're scared of you." "That's true. And the drubbing they received was well-deserved. I'm a patient man, but there are occasions—" "Come along, please," Zubb called. "Another ten minutes' walk—" "Look here, Zubb." Magnan shook a finger at the tall alien. "How is it "Come softly, now." Zubb beckoned, moving toward a bend in the bird-kneed, bearing steaming platters, stood in groups of three strumming slender bottle-shaped lutes, or pranced an intricate-patterned dance, unnoticed in the shrill uproar as each of "Ah, a moment," Zubb said. "Observe the Qornt—the tallest of the "And now an interview with the Qorn himself," Zubb shrilled. "If you'll Retief turned. Zubb stood gripping an ornately decorated power pistol "I suspected you had hidden qualities, Zubb," Retief commented. "See here, Zubb! We're diplomats!" Magnan started. "Careful, Mr. Magnan you may goad him to a frenzy." "By no means," Zubb whistled. "I much prefer to observe the frenzy anything that annoys the Qornt, it's Qornt-like behavior in others. Now step along, please." "I doubt it." "You'll face the wrath of Enlightened Galactic Opinion!" Qorn turned as Retief came up, blinking three-inch eyes. Zubb stepped Zubb finished his speech and fell silent, breathing hard. no !" Zubb twittered. Qorn cocked an eye, motioned to a servant. "Chain that "Stay back!" Qorn hooted. "Stand over there where I can keep an eye on don't want peace! I've had a surfeit of peace these last two centuries! I want action! Loot! Adventure! Glory!" He turned to look down the table. "How about it, fellows? It's war to the knife, eh?" There was a momentary silence from all sides. "I guess so," grunted a giant Qornt in iridescent blue with anyway," he added. "They do whatever I convince them they ought to do." "But I'm sure that on more mature consideration—" "I can lick any Qornt in the house." Qorn said. "That's why I'm Qorn." He belched again. "Let them go," the blue and flame Qornt said glumly. "You can do better than that," Qorn hooted. "Now here's a suggestion: we carve them up a little—lop off the external labiae and pinnae, say—and ship them back." "Good lord! Retief, he's talking about cutting off our ears and sending us home mutilated! What a barbaric proposal!" "It should have the effect of stimulating the Terries to put up a reasonable scrap," Qorn said judiciously. "I have a feeling that they're thinking of giving up without a struggle." "Oh, I doubt that," the blue-and-flame Qornt said. "Why should they?" Qorn rolled an eye at Retief and another at Magnan. "Take these two," he hooted. "I'll wager they came here to negotiate a surrender!" "Well," Magnan started. like to fight." "I'm afraid you've gotten the wrong impression, your Excellency," Retief said blandly. "We didn't come to negotiate. We came to deliver an Ultimatum." "What?" Qorn trumpeted. Behind Retief, Magnan spluttered. "We plan to use this planet for target practice," Retief said. "A new Zubb screeched, waved the guns. The Qornt were jabbering. "I told you they were brutes," Zubb shrilled. Qorn slammed his fist down on the table. "I don't care what they are!" "That's all right. They don't have one." "But—" "We'll take you on!" Qorn French-horned. "We're the Qorn! We glory in rest of the boys would listen to reason—" "Over my dead body!" "My idea exactly," Retief said. "You claim you can lick any man in the house. Unwind yourself from your ribbons and step out here on the floor, and we'll see how good you are at backing up your conversation." "But that phenomenal reach—" "I'll peck away at him at knee level.
