DOWN TO THE WORLDS OF MEN BY ALEXEI PANSHIN The ancient rule was sink or swim—swim in the miasma of a planet without spaceflight, or sink to utter destruction! nobody bothered to laugh at, and then we were all silent. I was feeling My name is Mia Havero. I'm fourteen, of course, or I wouldn't be 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 leave that way, but George thinks it's fun to be a hot pilot. partners with the competition, do you? Besides, there was still that crack about being a snob. The planet chosen for our Trial was called Tintera. The last contact the Ship had had with it—and we were the ones who dropped them—was 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 kids because they never tell you anything about the place they're going to drop you. All I knew was the name. I wouldn't have known that much if Daddy weren't Chairman of the Council. I felt like crawling in a corner of the ship and crying, but nobody else was breaking down, so I didn't. I did feel miserable. I cried when It wasn't the chance of not coming back that bothered me really, because I never believed that I wouldn't. The thought that made me unhappy was that I would have to be on a planet for a whole month. Planets make me feel wretched. The gravity is always wrong, for one thing. Either your arches and calves ache or every time you step you think you're going to trip on a piece of fluff and break your neck. There are vegetables everywhere and little grubby things just looking for you to crawl on. If you can think of anything creepier than that, you've got a real nasty 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 not for me. 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 sea from the morning side and then dropped low over gray-green forested Jimmy—if he would get back alive. It's no game we play. When we turn fourteen, they drop us on the nearest colonized planet and come back one month later. That may sound like fun to you, but a lot of us never come back alive. Don't think I was helpless. I'm hell on wheels. They don't let us grow 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 have anything to do with Jimmy. I just couldn't stand to put off the bad moment any longer. The ship lifted impersonally away from Ninc and me like a rising bird, and in just a moment it was gone. Its gray-blue color was almost the color of the half-overcast sky, so I was never sure when I saw it last. The first night was hell, I guess because I'm not used to having the the dark. When the sun disappears, somehow you wonder in your stomach 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 Earth. Considering how short a time it was in which the colonies were established, there was not time to set up industry, so they had to have draft animals. were planted. I don't know how many of those planets had animals that could made a wordless, chilling, lowing sound as they milled and plodded along. He seemed exasperated. I have that effect sometimes. Even on Mother and I looked down at the plodding, unhappy creatures they were driving I felt uncomfortable. I said, "I don't think so." 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. After twenty minutes of easy riding for us and hard walking for the them now." I dug my heels into Ninc's sides and rode on. At the next mind and rode on, feeling good. I think I even giggled once. Sometimes I even convince myself that I'm hell on wheels. III When I was nine, my Daddy gave me a painted wooden doll that my the green creatures, which surprised me since the ones I'd seen before hadn't seemed smart enough to count to one, let alone do any work. But it relieved me. I thought they might have been eating them or something. a jolt that sickened me. By the time I came out on the other side, I was sick. My hands were cold and sweaty and my head was spinning, and I wanted to kick Ninc to but I decided I'd not tell anybody different until I found what made the clocks tick on this planet. But that wasn't what bothered me. It was the kids. My God! They four then—these people were Free Birthers! I felt a wave of nausea and I closed my eyes until it passed. 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 eight billion people. But, no. They bred and they spread and they devoured everything in wouldn't be here. That may not scare you, but it scares me. What happened before, when people didn't use their heads and wound up blowing the Solar System apart, is something nobody should forget. The older people don't let us forget. But these people had, and that the Council should know. For the first time since I landed on Tintera, I felt really frightened. There was too much going on that I didn't understand. I felt a blind urge to get away, and when I reached the edge of town, I had gone wrong. I reached down into my saddlebag and brought out my contact signal. drop the stomach out of everybody aboard. George Fuhonin's style. I triggered the signal, my heart turning flips all the while. I didn't know why he was back, but I wasn't really sorry. bucking so hard that I knew this wasn't hot piloting at all, just plain idiot stutter-fingered stupidity at the controls. As it skidded by me I felt defeated and tired. Not much farther along the road, I came to children tried to pack them off to bed. But they weren't ready to go, it seemed just right. nice little girl, and to get rid of the kid, she sent her on a phony errand into the deep dark woods at nightfall. I could appreciate the poor girl's position. All the little girl had to help her were the handkerchief, the comb and the pearl that she had inherited from her A voice there said, "I'll be damned if I'll take another day like this one, Horst. We should have been here hours ago. It be your fault we're night. I should have used my head. I hadn't and now it was time to take I opened my mouth to scream—I have a good scream—but a rough smelly dragging me and dropped me in a heap. "Make any noise," he said, "and I'll hurt you." "Why would they be doing that?" I asked. I slipped my hand under my jacket. "Every time you open your mouth you shout that you be off one of the I felt like a fool. until it cracked and fell apart.
