in the miasma of a planet without spaceflight, or sink to utter destruction!

There were sixteen of us girls and thirteen boys. We took our places lost and just beginning to enjoy it when Jimmy Dentremont came over to me. He's red-headed and has a face that makes him look about ten. An intelligent runt like me. He said what I expected. "Mia, do you want to go partners if we can get together when we get down?" back to his place without saying anything. My name is Mia Havero. I'm fourteen, of course, or I wouldn't be telling this. I'm short, dark and scrawny, though I don't expect that scrawniness to last much longer. Mother is very good looking. In the meantime, I've got brains as a consolation. After we were all settled, George Fuhonin, the pilot, raised the ramps. We sat there for five minutes while they bled air out of our tube and then we just ... dropped. My stomach turned flips. We didn't have to The planet chosen for our Trial was called Tintera. The last contact almost 150 years ago. No contact since. That had made the Council debate a little before they dropped us there, but they decided it was all right in the end. It didn't make any practical difference to us We have a place in the Ship like that—the Third Level—but it's only a thousand square miles and any time it gets on your nerves you can go up a level or down a level and be back in civilization. When we reached Tintera, they started dropping us. We swung over the gear and then led his horse down the ramp. I think he was still smarting from the slap I'd given him. In a minute we were airborne again. I wondered if I would ever see Jimmy—if he would get back alive. It's no game we play. When we turn fourteen, they drop us on the Don't think I was helpless. I'm hell on wheels. They don't let us grow for fourteen years and then kick us out to die. They prepare us. They do figure, though, that if you can't keep yourself alive by the time you're fourteen, you're too stupid, foolish or unlucky to be any use to the Ship. There's sense behind it. It means that everybody on the Ship thirty gone. I rode in a spiral search pattern during the next two days. I had three things in mind—stay alive, find people and find some of the others. I could fit into for a month. If not, I would have to find a place to camp out, as nasty as that would be. The third was to join forces, identify. One of the smartest moves in history was to include horses when established, there was not time to set up industry, so they had to have draft animals. The first of the Great Ships was finished in 2025. One of the eight, as well as the two that were being built then, went up with everything 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 were five men on horseback herding a bunch of the ugliest creatures alive. There be escaped Losels in these woods." I told you I hadn't finished filling out yet, but I hadn't thought it was that bad. I wasn't ready to make a fight over the point, though. 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 I felt uncomfortable. I said, "I don't think so." What the man did then surprised me. He said, "I do think so," and didn't want to be fried. I said, "Ease your rifles out and drop them gently to the ground." They did, watching me all the while with wary expressions. When all the rifles were on the ground, I said, "All right, let's go." They didn't want to move. They didn't want to leave the rifles. I didn't trust the crazy kid not to shoot. After twenty minutes of easy riding for us and hard walking for the creatures, I said, "If you want your rifles, you can go back and get them now." I dug my heels into Ninc's sides and rode on. At the next bend I looked back and saw four of them holding their packhorses and the creatures still while one beat a dust-raising retreat down the road. I put this episode in the "file and hold for analysis" section in my mind and rode on, feeling good. I think I even giggled once. Sometimes I even convince myself that I'm hell on wheels. III great-grandmother brought from Earth. The thing is that inside it, nestled one in another, are eleven more dolls, each one smaller than stone, wood and brick. Out of date. Out of time, really. There were no machines more complicated than the trucks I'd seen earlier. At the 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 wouldn't have died. There wouldn't have been eight billion people. 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. I am lucky. My great-great-grandparents were among those who had enough For the first time since I landed on Tintera, I felt really I reached down into my saddlebag and brought out my contact signal. The scoutship swung up in the sky in a familiar movement calculated to drop the stomach out of everybody aboard. George Fuhonin's style. I takes an advanced technology to build. I felt defeated and tired. Not much farther along the road, I came to a campsite with two wagons pulled in for the night, and I couldn't 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 That was a silly way to put it, but somehow it said more than if he'd threatened to break my arm or my head. It left him a latitude of things my jacket. Horst turned back to me and I said, "You can't do this and get away with it." He said, "Look, boy. You may not know it, but you be in a lot of trouble. So don't give me a hard time." "The courts won't let you get away with this," I said. I'd passed a courthouse in the town with a carved motto over the doors: EQUAL jacket. "Every time you open your mouth you shout that you be off one of the Ships," Horst said. "That be enough. They already have one of you brats in jail in Forton." this be for." He held out my pickup signal. Horst looked at it, then handed it back. "Throw it away," he said. I leveled my gun at them—Hell on Wheels strikes again! I said, "Hand that over to me." Horst made a disgusted sound. "Don't make any noise," I said, "or you'll fry. Now hand it over." I stowed it away, then paused with one hand on the leather horn of the enough," to the others who'd come up behind me. I felt like a fool. said in a voice far colder than mine could ever be, because it was natural and mine wasn't, "The piece be yours." Then he tromped on it until it cracked and fell apart.
