"Niven, Larry - Building Harlequin's Moon" - читать интересную книгу автора (Niven Larry)

Just as they were leaving for the meadow, Rachel looked up at the tool tent. Familiar tips of leaves rose above the edge of the roof. Her cecropia! But what could she say now? It had to be Andrew; he didn't have the common sense to be careful around Council. He was such a stupid show-off. Now he'd probably got them both in trouble, and worse, he probably didn't care. She grimaced and walked on, keeping her silence.
Plastic and stone shapes dotted the meadow. Council had made them by fusing gathered pebbles and tiny chondrules from asteroids, covering the result with a soft and clear plastic compound. Useful art; neatly shaped into benches and sometimes into wild swirling sculptures. They had been there all of Rachel's life.
She'd asked about them once, and Gabriel had said, "Wayne and Ali were bored one year."
The First Trees surrounded the meadow on three sides. Gabriel and Ali planted them, by themselves, even before any Earth Born were awakened. There were kapoks and figs and palms and gray ciebas just starting to grow the buttressing roots that would someday be large enough to climb as if they were trees themselves. Rachel struggled with Council's complicated year-math. Rachel's mother Kristin was Earth Born, her father one of the first generation of Moon Born, and Rachel was born when he was forty-two Moon years old, or just over half that many Earth years, and his parents had been awake two Moon years before they had him, so the trees surrounding the meadow must be ... twenty-five Earth years or more old. They were tall, the biggest more than a hundred feet. Branches intertwined tightly, even fifty feet above the forest floor. Webs of thin young lianas, vines, curled up trunks and hung down from branches, reaching for ground and sky together. Light in this part of the grove shone low and hazy, mysterious. The air smelled damp and rich, as if the canopy held in the scents of growth. It was Rachel's favorite place.
Once, Gabriel had told her that the First Trees were planted too close together. He had miscalculated how much Selene's oxygen-rich atmosphere and three-quarter Earth gravity would elongate everything that grew on the moon—stems, and branches, and people. He'd said trees were shorter and fatter on Earth. Rachel liked the intertwined effect—it made the First Forest dark and intriguing.
Gabriel's voice brought her back to the present. "Now we move on to the practical. Your combined score determines whether or not you become a Horticulture Terraformer. If you don't pass, there are other choices for work."
Rachel's stomach clenched. Not me. I have to be around trees. I have to help plant Selene. I have to pass! She imagined her father's voice in her ear, suggesting she "breathe," saying, "My daughter can do anything."
"Some of our evaluation will be based on the work you did during class. That tells us how you approach day-to-day tasks," Gabriel said. A few children groaned. Ursula and Rachel grinned at each other; this was good for them, they worked hard. "We'll also judge how well you've learned the system's ecology behind terraforming. First, Ali will question you as a group."
Rachel and Ursula sat next to each other. They squeezed each other's hands, passing a wish for luck back and forth. Ali faced the class, sitting cross-legged on a waist-high black dais. She opened a data window beside her, opaqued it white, and left it suspended in air to her right. "First, tell me what is in the base nutrient mixture?"
An easy question. Rachel chose to let one of the younger children answer it. Two of them, and Andrew, all registered an answer at almost the same time.
Ali called on the young blond boy Andrew had teased earlier, Nick, and his answer appeared in the window beside Ali. His voice started with a quiver of nerves, but got stronger as he listed, "Nitrogen, silicon, phosphorus, and potassium are macro-nutrients. Calcium, magnesium—" Nick stumbled through the rest, getting most of it right.
"Anyone else?" Ali asked.
"Iron," Sharon spoke up.
"But we get iron from the soil," Andrew said.
"We still have to measure it; there's too much in some places," Sharon answered him.
"Quite right. Why is it irregular?" Ali asked.
"Well, here, in the grove, it's pretty even. All Selene's soil came from space stuff, and in some places, the way you made the world, it didn't work. It came out scattered." Sharon put her hand over her mouth. Some of the other children tittered.
Rachel tried to cover for Sharon. "It wasn't a mistake, it couldn't be helped. Some asteroids and moons have more iron than others. Besides, everything else varies too. We have to watch places where there is too much iron—it burns the roots. We always survey the soil before we plant, especially in the field." Rachel grinned at the younger girl. "And you're right, iron is important. There has to be some, and there can't be too much."
"But every nutrient is like that," Andrew said. "They all have to be just right."
Sharon didn't answer. Andrew had succeeded in making Rachel look foolish too. Rachel squirmed, furious for the second time that morning. She couldn't show her anger—it might make her fail. It was easy to earn Council's disapproval. She looked over at Sharon, who gave her a beseeching glance. Rachel smiled, the only help she could afford to offer.
Ali shifted her questioning to Andrew, perhaps to give Sharon time to recover her composure. Andrew delivered a well-organized example of the way the tiny measuring pods communicated wirelessly with one another, collecting and sending information about soil, atmosphere, and any plants they were attached to. The pods were ubiquitous—data flowed from all over Selene to be gathered up at Aldrin and forwarded to space, to the carrier ship John Glenn. Ali pushed him quietly, eventually questioning past his ability to answer confidently.
Question and answer had been running for an hour now. Rachel was so mad at Andrew she could spit. He'd monopolized all of the best questions. Some of her answers were better, but Andrew didn't give her time to say them. And what Andrew hadn't answered, quiet Harry had answered perfectly. Rachel couldn't smack Andrew in front of Council, and she couldn't seem to think faster either. Ursula hadn't done too well; Rachel wanted to prod her out of her shyness. Things were not going well.
Finally Ali looked over at the two girls and asked them, "Why do we plant in this grove with our hands and not with machines?"
Andrew started to talk, but Ali pushed an open hand toward him to warn him off, and he closed his mouth again, fidgeting. Rachel glanced at Gabriel—they'd talked about this once on a walk. She licked her lips. "So that we get a feel for the plants and see them as living parts of an ecosystem. If we touch the plants, and know them, we can remember that later, when we are using mostly machines." She looked at Ursula. "Ursula knows this too."
Ursula looked gratefully back at Rachel and narrowed her eyes, plunging in bravely. "When we work by hand we know what the soil feels like. We know what the tree feels like." Ursula hesitated a second. "And it's ours, so we're proud of our work here."
Ursula ran out of words and elbowed Rachel, who said, "Terraforming Ecology is a form of engineering. Gabriel says engineers need to do things themselves to understand how to avoid mistakes."
Ali broke in, "Do you think that's true?"
Rachel stayed quiet for a moment. "Yes. I think we'll know the plants better. I'll always know the ones I planted here, and if I want to keep that, I'll stay in some physical contact even when—if—I pass and work on planting machines."
Andrew interrupted, "Besides, who'd want machines tearing up our soil? They were already here once: this whole grove has been prepared with the right basic soil. Why use machines where you don't need them?"
Of course, Rachel thought, that must have been the right answer. Why do I always miss the simple stuff?
Gabriel changed the subject. "While you were talking with Council-woman Ali, I downloaded some problems for you. You've got an hour, so take your time, but stay here in the meadow."
The children separated and bent over their wrist pads. Rachel answered half of the questions easily, and struggled with the next few, sweat beading on her forehead as time ticked away too fast. Knowing that there must be cameras recording, Rachel kept her face turned toward her pad and didn't look around at all.
After they'd all sent their answers back to Gabriel, the children scattered for lunch. Ursula and Rachel sat together. At first the girls ate quietly, swapping carrots for berries, and sharing two types of bread. Ursula looked dejected. "I didn't even get through it all. What happens if I'm not picked?"
"I didn't have time to finish the last question either," Rachel said. "And besides, we don't know how the others did yet."
"I missed three. But I know Harry and Andrew finished it all."
"How do you know that?" Rachel asked her friend.
"I watched them. They beamed the answers even before the hour was up."
"That doesn't mean they got them right." Ursula didn't look comforted. "Hey," Rachel offered, "you always did well planting, and the whole time we were studying with Gabriel. I know he thinks you're smart."
"How do you know that?" Ursula asked.
"I watch him. I see him watching how you work, and sometimes he smiles."
"What does a smile mean? What if I don't get chosen? I'll just die if I don't pass," Ursula continued. "What if I have to be a cook, or make tents? I want to be with you!"
"Well, it looks like we get to find out."
Gabriel and Ali sat together on the dais, waiting for the students to notice and gather. Harry already sat at the Council's feet, but the others, including Andrew this time, were all busy in a game of catch-the-disk, seeing who could leap highest and still land gracefully, disk in hand. Andrew's bracelets jangled against each other so he rang loudly as he leaped, a signal for the other children to get out of his way. Andrew was one of the best players, and Rachel watched him catch the heavy disk with his feet, flip over in a one-eighty, and land triumphantly.
Ali clapped her hands and the players stopped and bounded over.
Gabriel started right in on the results. "Nick, you and Alexandra are the youngest two to pass. You'll be in the advanced class next winter." That meant that at least three younger children, including Sharon, didn't pass. A groan came from the small knot of younger children. They'd all have to start over, most in different classes. They'd become simple farmers or get training for other town jobs.
Gabriel ignored it. "Eric, Julie, and Kimberly, you all passed. You get a break until Ali and I get back from planting." The four oldest students—Harry, Rachel, Ursula, and Andrew—all looked at each other. It wasn't possible they'd all failed, but Rachel's heart sank.
Gabriel's next words made it worse. "I want Andrew, Harry, Rachel, and Ursula to stay. Everyone else can leave."
Rachel did her best to sit still while the others left. A knot of anxiety drummed at the top of her stomach, seeking release. She swallowed. Minutes passed, and Gabriel and Ali said nothing. Finally the meadow only contained the six of them.
Ali opened a new data window, larger than the one they'd used in the test. It showed darkness, and then the flash of a hand light bobbing as a dark figure walked down a path. Rachel squinted—it looked like—a human covered by tent material. Then the figure that held the light bent down and pulled up a tree; Rachel's cecropia. As a hand reached for the plant, the tent fabric slipped for a moment. Metal rings glittered briefly in a flash of light across the wrist.
No one said anything for a long time. Rachel looked at Andrew, who looked at the ground.
