The ancient rule was sink or swim—swim in the miasma of a planet without me. He's red-headed and has a face that makes him look about ten. An intelligent runt like me. telling this. I'm short, dark and scrawny, though I don't expect that meantime, I've got brains as a consolation. Thinking it over, I was almost sorry I'd been stinking to Jimmy D. He's partners with the competition, do you? Besides, there was still that crack about being a snob. Planets make me feel wretched. and little grubby things just looking for to crawl on. If you imagination. Worst of all, planets stink. Every single one smells—I've been on enough to know that. A planet is all right for a Mud-eater, but gear and then led his horse down the ramp. I think he was still smarting from the slap I'd given him. is a person who can take care of himself if he has to. Daddy says that something has to be done in a closed society to keep the population from decaying mentally and physically, and this is it. And it helps to camp out, as nasty as that would be. The third was to join forces, No, he isn't really a meatball. The trouble is that I don't take nothing from nobody, especially him, and he doesn't take nothing from nobody, especially me. So we do a lot of fighting. In two days of riding, I ran onto nothing but a few odd-looking animals. I shot one small one and ate it. It turned out to taste pretty identify. One of the smartest moves in history was to include horses when they dropped the colonies. I say "they" because, while we did the actual dropping, the idea originated with the whole evac plan back on established, there was not time to set up industry, so they had to have draft animals. could have been substituted but, even if they had, they would have had to be domesticated from scratch. That would have been stupid. I'll bet that half the colonies would have failed if they hadn't had horses. I came on my first travelers three hours later. I rounded a tree-lined bend, ducking an overhanging branch, and pulled Ninc to a stop. There were five men on horseback herding a bunch of the ugliest creatures alive. They were green and grotesque. They had squat bodies, long limbs and knobby bulges at their joints. They had square, flat animal masks for faces. But they walked on their hind legs and they had paws that were almost hands, and that was enough to make them seem almost human. They made a wordless, chilling, lowing sound as they milled and plodded men on horseback had guns in saddle boots. They looked as nervous as cats with kittens. One of them had a string of packhorses on a line and he saw me and called to another who seemed to be the leader. That one wheeled his black horse and rode back toward me. He was a middle-aged man, maybe as old as my Daddy. He was large and he had a hard face. Normal enough, but hard. He pulled to a halt when we me. I believe in judging a person by his face. A man can't help the face he owns, but he can help the expression he wears on it. If a man looks mean, I generally believe that he is. This one looked mean. That was why I kept riding. He said, "What be you doing out here, boy? Be you out of your head? There be escaped Losels in these woods." Daddy, who should know better. better ride on from here with us. For protection." He had an odd way of twisting his sounds, almost as though he had a mouthful of mush. I wondered whether he were just an oddball or whether all. We mought as well throw him back again." The rider looked at me. When I didn't dissolve in terror as he expected, he shrugged and one of the other men laughed. The hard man said to the others, "This boy will be riding along with us I looked down at the plodding, unhappy creatures they were driving didn't want to be fried. tones said, "Look here, kid...." "Shut up," I said, in as mean a voice as I could muster, and he did. It surprised me. I didn't think I sounded that mean. I decided he just the creatures still while one beat a dust-raising retreat down the road. the green creatures, which surprised me since the ones I'd seen before But it relieved me. I thought they might have been eating them or silently past. And I overtook a wagon driven by the oldest man I've the boys and men wore pants, and so did I, which must have been why Horst and his buddies assumed I was a boy. It wasn't flattering but swarmed. I saw a family come out of a house—a father and four children. It was the most foul thing I've ever seen. It struck me The first thing you learn in school is that if it weren't for idiot and criminal people like these, Earth would never have been destroyed. The evacuation would never have had to take place, and eight billion people been eight billion people. But, no. They bred and they spread and they devoured everything in their path like a cancer. They gobbled up all the resources that Earth had and crowded and shoved one another until the final war came. foresight to see what was coming. If it hadn't been for them and some others like them, there wouldn't be any humans left anywhere. And I wouldn't be here. That may not scare you, but it scares me. Who? Make the mistake of bracing a fellow like Horst and you might wind drop the stomach out of everybody aboard. George Fuhonin's style. I idiot stutter-fingered stupidity at the controls. As it skidded by me we wouldn't tell these Mud-eaters how, a scoutship is something that buildings on it. One was a well enclosure and the other was little more playing, and one of them ran close to the high-walled pen. His father had two or three brothers and sisters, but it didn't strike me until that moment that it wouldn't even seem out of the ordinary to these kids. Isn't that horrible? errand into the deep dark woods at nightfall. I could appreciate the not." who'd made the joke about me being beneath the notice of a Losel. He I opened my mouth to scream—I have a good scream—but a rough smelly lungful of air. I bit down hard—5000 lbs. psi, I'm told—but he and dragged me off. When we were behind the pen and out of earshot of the fire, he stopped dragging me and dropped me in a heap. "Make any noise," he said, "and I'll hurt you." That was a silly way to put it, but somehow it said more than if he'd for that. "I ought to club you anyway," he said. The one I'd dropped the saddle on came up then. The others were putting the animals in the pen. He started to kick me, but Horst stopped him. "No," he said. "Look through the kid's gear, bring the horse and what being kicked, but was rather establishing who did the kicking in his bunch. with it." trouble. So don't give me a hard time." He still thought I was a boy. It was not time to correct him, but I didn't like to see the point go unchallenged. It was unflattering. something stuffy like that. He laughed, not a phony, villian-type laugh, but a real laugh, so I knew I'd goofed. "Every time you open your mouth you shout that you be off one of the saddle. "What's the name of the kid in jail in Forton." natural and mine wasn't, "The piece be yours." Then he tromped on it Brains are no good if you don't use them.
