worlds, with only an occasional visa problem, or perhaps a distressed "Travel!" the consul barked. "I hate travel. Here in this backwater representing the primary. He picked up a pointer, indicating the innermost planet. "The situation on Adobe is nearing crisis. The confounded settlers—a mere handful of them—have managed, as usual, to stir up trouble with an intelligent indigenous life form, the Jaq. I can't think why they bother, merely for a few oases among the endless deserts. However I would look very bad in my record, so I shall expect results." He passed the buff envelope across to Retief. "I understood that Adobe was uninhabited," Retief said, "until the Terrestrial settlers arrived." "Apparently, that was an erroneous impression." Passwyn fixed Retief Sector. You need merely implement it. Is that entirely clear?" "Has anyone at Headquarters ever visited Adobe?" "Of course not. They all hate travel. If there are no other questions, "They shore won't, sonny. I ain't givin' 'em the chance." He started heavy old-fashioned power pistol. "Long as you're goin' in, might as well take this." open. A wave of hot jungle air struck him. He lowered himself to a bed of shattered foliage, got to his feet ... and dropped flat as a bullet whined past his ear. Retief edged back around the trunk, eased down behind a fallen log. A stocky man in grimy leather shirt and shorts appeared, moving cautiously, a pistol in his hand. As he passed, Retief rose, leaped the log and tackled him. They went down together. The stranger gave one short yell, then struggled in silence. Retief flipped him onto his back, raised a fist— "Hey!" the settler yelled. "You're as human as I am!" "Maybe I'll look better after a shave," said Retief. "What's the idea of shooting at me?" "Lemme up. My name's Potter. Sorry 'bout that. I figured it was a Flap-jack boat looks just like 'em. I took a shot when I saw something move. Didn't know it was a Terrestrial. Who are you? What you doin' lay. "I'm glad you're a poor shot. That missile was too close for comfort." "Missile, eh? Must be Flap-jack artillery. We got nothing like that." "I heard there was a full-fledged war brewing," said Retief. "I didn't expect—" "Good!" Potter said. "We figured a few of you boys from Ivory would be revolvers belted across his paunch. "We can use every hand. We're in bad shape. We ran into the Flap-jacks three months ago and we haven't made a smart move since. First, we thought they were a native form we hadn't run into before. Fact is, one of the boys shot one, thinkin' it was fair game. I guess that was the start of it." He stirred the fire, added a stick. "And then a bunch of 'em hit Swazey's farm here," Potter said. "Killed two of his cattle, and pulled back." "I figure they thought the cows were people," said Swazey. "They were out for revenge." "How could anybody think a cow was folks?" another man put in. "They don't look nothin' like—" "Don't be so dumb, Bert," said Swazey. "They'd never seen Terries before. They know better now." Bert chuckled. "Sure do. We showed 'em the next time, didn't we, Potter? Got four." "They walked right up to my place a couple days after the first time," Swazey said. "We were ready for 'em. Peppered 'em good. They cut and run." "Flopped, you mean. Ugliest lookin' critters you ever saw. Look just "It's been goin' on this way ever since. They raid and then we raid. "We heard they were sending some kind of bureaucrat in here to tell and Verde." "Shut up, you damn fool!" a deep voice grated. "Lemuel!" Potter said. "Nobody else could sneak up on us like that." "If I'd a been a Flap-jack I'd of et you alive," the newcomer said, A short-nosed automatic appeared in Lemuel's hand, a clashing note against his fringed buckskins. "Skip the talk. I know a fink when I see one." stumbled back, blood starting from his nose the pistol fired into the "What's the idea...?" He sat down on the ground to wait. It was ten minutes before a movement caught his eye. Something had "Sorry, fellow," he muttered between clenched teeth. "Eye-gouging isn't gentlemanly, but it's effective...." "Prisoners? But we have no prisoners." d'Yquem. "It was an unexpected pleasure to encounter your party here," said Hoshick. "I confess at first we took you for an indigenous earth-grubbing form, but we were soon disabused of that notion." He a bore, screening the spawn for deviations. Though I confess we've come upon some remarkably useful sports. The rangerform such as you made captive, for example. Simple-minded, of course, but a fantastically keen tracker." A scratchy sound issued from the disk. "Pardon my laughter," Hoshick said, "but surely you jest?" "As a matter of fact," said Retief, "we ourselves seldom use weapons." "I seem to recall that our first contact of skirmishforms involved the use of a weapon by one of your units." "My apologies," said Retief. "The—ah—the skirmishform failed to recognize that he was dealing with a sportsman." specific life-forms." "Oh? Curious. What forms are those?" "Vermin. Or 'varmints' as some call them. Deadly antagonists, but lacking in caste. I don't want our skirmishforms thinking of such worthy adversaries as yourself as varmints." "Dear me! I hadn't realized, of course. Most considerate of you to point it out." Hoshick clucked in dismay. "I see that skirmishforms are much the same among you as with us: lacking in perception." He laughed scratchily. "Imagine considering us as—what was the word?—varmints." "Which brings us to the crux of the matter. You see, we're up against two individuals settle the issue between them." "I ... um ... fear I don't understand. What possible significance could one attach to the activities of a couple of random skirmishforms?" don't involve the skirmishforms at all. That's quite passe." rearing up before him, his trappings gone. A silent rank of Flap-jack retainers were grouped behind him. the usual punching, shoving and kicking." It was like burial under a dump-truck-load of concrete. He remembered the rangerform he had captured. The sensitive orifice and probed. hide. "Suddenly I yearn for the crowded yellow sands of Jaq. I had "To tell you the truth, I'm old-fashioned myself. I'd rather watch the action from a distance too." "But surely your spawn-fellows would never condone such an attitude."
