Flux

So the Bell’s own magfield shell had thrown him. Big joke.

Logue would probably have told him off for not anticipating this, he realized. Laughed at him as well, to drive home the point.

Farr’s fear turned to anger. He looked forward to the day when he would no longer have so much to learn… and he could maybe administer a few lessons of his own.

His self-control returning, Farr began to make his clumsy way back to the Bell. “Give me the ropes,” he said.

The huge lumber caravan was visible for many days before it reached Qos Frenk’s ceiling-farm.

Dura, descending from a wheat-field at the end of a shift, watched the caravan’s approach absently. It was a trace of darkness on the curving horizon, a trail of tree trunks toiling through the vortex lines from the wild forests on the upflux fringe of the hinterland, on its way to the City at the furthest downflux. She wasn’t too interested. The hinterland sky, even this far from Parz, was never empty of traffic. The caravan would pass in a couple of days, and that would be that.

But this caravan didn’t go by so quickly. As time wore on it continued to grow in her vision, and Dura slowly came to appreciate the caravan’s true scale, and the extent to which distance and perspective had fooled her. The train of severed tree trunks, stretched along the vortex lines, must have extended for more than a centimeter. And it was only when the caravan approached its nearest point to the farm that Dura could make out people traveling with the caravan — men and women Waving along the lengths of the trunks, or tending the teams of Air-pigs scattered along the trunks’ lengths, utterly dwarfed by the scale of the caravan itself.

Another shift wore away. Rubbing arms and shoulders left stiff by a long day’s crop-tending, Dura slung her Air-tank over her shoulder and Waved slowly toward the refectory.

Rauc came up to her. Dura studied her curiously. Rauc had become something of a friend to Dura — as much of a friend as she had made here, anyway — but today the slim little coolie seemed different. Distracted, somehow. Although Rauc too had just finished a shift, she’d already changed into a clean smock and combed her hair free of dirt and wheat-chaff. The smile on her thin, perpetually tired face was nervous.

“Rauc? Is something wrong?”

“No. No, not at all.” Rauc’s small feet twisted together in the Air. “Dura, have you got any plans for your off-shift?”

Dura laughed. “To eat. To sleep. Why?”

“Come with me to the caravan.”

“What?”

“The lumber caravan.” Rauc pointed down beneath her feet, to where the caravan toiled impressively across the sky. “It wouldn’t take us long to Wave down there.”

Dura tried to conceal her reluctance. No thanks. I’ve already seen enough of the City, the hinterland, of new people, to last me a lifetime. She thought with a mild longing of the little nest she’d been able to establish for herself on the fringe of the farm — just a cocoon, and her little cache of personal belongings, suspended in the open Air, away from the cramped dormitories favored by the rest of the coolies. “Maybe another time, Rauc. Thanks, but…”

Rauc looked unreasonably disappointed. “But the caravans only pass about once a year. And Brow can’t always arrange an assignment to the right caravan; if we’re unlucky he ends up centimeters away from the farm when he passes this latitude, and…”

“Brow?” Rauc had mentioned the name before. “Your husband? Your husband’s with this caravan?”

“He’ll be expecting me.” Rauc reached out and took Dura’s hands. “Come with me. Brow’s never met an upfluxer before.”

Dura squeezed her hands. “Well, I’ve never met a lumberjack. Rauc, is this the only time you get to see your husband? Are you sure you want me along?”

“I wouldn’t ask otherwise. It will make it special.”

Dura felt honored, and she said so. She considered the distance to the caravan. “Will we have the time to get there and back, all in a single off-shift? Maybe we ought to go to Leeh and postpone our next shift — do a double.”

Rauc grinned. “I’ve already fixed it. Come on; find yourself something clean to wear, and we’ll go. Why don’t you bring your stuff from the upflux? Your knife and your ropes…”

Rauc followed Dura to her sleeping-nest, talking excitedly the whole way.

The two women dropped out of the ceiling-farm and descended lightly into the Mantle.

Dura dipped forward, extending her arms toward the caravan, and began to thrust with her legs. As she Waved she was still wondering if this was a good idea — her legs and arms still ached from her long shift — but after some time the steady, easy exercise seemed to work the pains from her muscles and joints, and she found herself relishing the comfortable, natural motion across the Magfield — so different from the cramped awkwardness of her work in the fields, with her head buried in an Air-mask, her arms straining above her head, her fingers thrust into the roots of some recalcitrant mutant plant.

The caravan spread out across the sky before her. It was a chain of Crust-tree trunks stripped of roots, branches and leaves; the trunks were bound together in sets of two or three by lengths of rope, and the sets were connected by more links of strong plaited rope. Dura had to swivel her head to see the leading and trailing ends of the chain of trunks, which dwindled with perspective among the converging vortex lines; in fact, she mused, the whole caravan was like a wooden facsimile of a vortex line.

Two humans hung in the Air some distance from the caravan. They seemed to be waiting for Rauc and Dura; as the women approached they called something and set off through the Air to greet them. It was a man and a woman, Dura saw. They were both around the same age as Rauc and Dura, and they wore identical, practical-looking loose vests equipped with dozens of pockets from which bits of rope and tools protruded.

Rauc rushed forward and embraced the man. Dura and the lumberjack woman hung back, waiting awkwardly. The woman was slim, strong-looking, with tough-looking, weathered skin; she — and the man, evidently Rauc’s husband Brow — looked much more like upfluxers than any hinterland or City folk Dura had met up to now.

Rauc and Brow broke their embrace, but they stayed close with their arms linked together. Rauc pulled Brow toward Dura. “Brow, here’s a friend from the farm. Dura. She’s an upfluxer…”

Brow turned to Dura with a look of surprised interest; his gaze flickered over her. He resembled Rauc quite closely. His body was lean, strong-looking under its vest, and his narrow face was kindly. “An upfluxer? How do you come to be working on a ceiling-farm?”

Dura forced herself to smile. “It’s a long story.”

Rauc squeezed Brow’s arm. “She can tell you later.”

Brow rubbed his nose, still staring at Dura. “We see upfluxers sometimes. In the distance. When we’re working in the far upflux, right at the edge of the hinterland. You see, the further upflux you go toward the wild forests, the better the trees grow. But…” He stopped, embarrassed.

“But the more dangerous it gets?” Dura maintained her smile, determined for once to be tolerant. “Well, don’t worry. I don’t bite.”

They laughed, but it was forced.

Rauc introduced the woman with Brow. She was called Kae, and she and Rauc embraced. Dura observed them curiously, trying to make sense of their relationship. There was a stiffness between Rauc and Kae, a wariness; and yet their embrace seemed genuine — as if on some level, beneath the surface strain, they shared a basic sympathy for each other.

Brow tugged at Rauc. “Come and see the others; they’ve missed you. We’re going to eat shortly.” He glanced at Dura. “Will you join us?”

The woman Kae approached Dura with brisk friendliness. “Dura, let’s leave these two alone for a while. I’ll show you around the caravan… I don’t suppose you’ve met people like us before…”

* * *

Dura and Kae Waved side by side along the length of the caravan. Kae pointed out features of the caravan and described how it worked in a brisk, matter-of-fact way, her talk laced with endless references to Dura’s assumed ignorance. Dura had long since grown tired of being treated as an amusing freak by these Parz folk, but — for today — she bit back the acid replies which seemed to come so easily to her. This woman, Kae, didn’t mean any harm; she was simply trying to be kind to a stranger.

Maybe I’m learning to look beneath the surface of people, Dura wondered. Not to react to trivia. She smiled at herself. Maybe she was growing up at last.

The chain of trunks slid through the Air at about half an easy Waving speed. There were teams of harnessed Air-pigs, their harness sets fixed — not to Air-cars — but to the rope links in the chain of trees. The pigs squealed and snorted as they hauled at their restraints of leather. Humans, some of them children, tended the animals. The pigs were fed bowls of mashed-up Crust-tree leaf, and their harnesses were endlessly adjusted to keep the teams hauling in the same direction, along the long line of trunks.

People hailed Kae as she passed, and they glanced curiously at Dura. Dura guessed there must be a hundred people traveling with this caravan.

The women paused to watch one team being broken up. The animals were released from their harnesses, but they were still restrained by ropes fixed to pierced fins. The animals were led away to be tied up in another part of the caravan to rest, while a fresh team was fixed into place.

Dura frowned at this. “Wouldn’t it be easier to stop the caravan, rather than try to change the pigs over in flight?”

Kae laughed. “Hardly. Dura, when the caravan is assembled, back on the edge of the upflux, it takes several days, usually, for the pig-teams to haul it up to speed. And once this mass of wood is moving, it’s much easier to maintain its motion than to keep stopping and starting it. Do you see?”

Dura sighed inwardly. “I know what momentum is. So you don’t even stop when you sleep?”

“We sleep in shifts. We sleep tied up to nets and cocoons fixed to the trunks themselves.” Kae pointed to the nearest pig-team. “We rotate the pigs in flight. It isn’t so difficult to steer a caravan; all you have to do is follow the vortex lines downflux until you get to the South Pole… Dura, a caravan like this never stops moving, once it sets off from the edge of the hinterland. Not until it’s within sight of Parz itself. Then the pig-teams are turned around, and the caravan’s broken up to be taken into the City.”

Dura tried to envisage the distance from the upflux to Parz. “But at this speed it must take months to reach the City.”

“A full year, generally.”

“A year?” Dura frowned. “But how can the City wait that long for lumber?”

“It can’t. But it doesn’t have to.” Kae was smiling, but there didn’t seem to be any impatience in her tone at Dura’s slowness. “At any time, there’s a whole stream of caravans like this, heading for the City from all around the circumference of the hinterland. From the point of view of Parz there’s a steady flow of the wood it needs.”

“Rauc knew on exactly which day to come down to the caravan. In fact, you and Brow were waiting to greet us.”

“Yes. We were on time. We always are, Dura; all the caravans are, right across the hinterland. It’s all carefully planned.”

Dura thought of dozens, hundreds perhaps, of caravans like this, endlessly converging on Parz with their precious lumber… and all on time. She felt awed at the idea of humans being able to plan and act systematically on such a scale, and with such precision.

They moved on along the length of the caravan. In some places the trunks had been opened up to expose the green glow of the wood’s nuclear-burning core. Humans moved around the glowing spots and circles, purposeful and busy. There were nets and lengths of rope trailing from the trunks, and Dura saw sleep cocoons, tools, clothes, food bales tucked into the nets. In one place there was a little clutch of infants and small children, safely confined inside a fine-meshed net.
