“Farr. Send him.”

Dura stared at the woman’s hard, empty-eyed expression; anger and fear radiated out, shocking her. “Farr’s just a kid. You can’t be serious, Philas.”

“Not me.” Philas shook her head stiffly, the muscles of her neck stiff with rage. “I’m not getting in that thing, to be taken away. No. I’d rather die.”

And Dura, despairing, realized that the widow meant it. She tried for some while to persuade Philas, but there was no chink in the younger woman’s resolution.

“All right, Philas.” Problems revolved in her head: the tribe, Farr… Her brother would have to come with her, in the car, of course. Adda had been correct in intuiting that Dura would never be able to relax if Farr were out of her sight for long. She said to Philas, “Here is what you must do.” She squeezed the woman’s hand, hard. “Go back to the Human Beings. Tell them what has happened. That we are safe, and that we’re going to get help for Adda. And we’ll return if we can.”

Philas, her transfixing terror abating, nodded carefully.

“They must hunt again. Tell them that, Philas; try to make them understand. Despite what’s befallen us. Otherwise they’ll starve. Do you understand? You must tell them all this, Philas, and make them hear.”

“I will. I’m sorry, Dura.”

Dura felt an impulse to embrace the woman then; but Philas held herself away. The two women hovered in the Air, unspeaking, awkward, for a few heartbeats.

Dura turned away from Philas to face the door of the car. It was dark in there, like a mouth.

Terror spurted in her, sudden and unexpected. She fought to move forward, to keep from shivering.

She was scared of the car, of Parz City, of the unknown. Of course she was. She wondered now if that fear, lurking darkly at the back of her head, was truly what had impelled her to order Philas to go with Toba, regardless of any other justification. And she wondered if Philas had perceived that, too.

Here was another layer, she thought tiredly, to add to an already overcomplex relationship. Well, maybe that was the nature of life.

Dura turned and climbed slowly into the car; Farr, wordless, meek, followed.

The man from the Pole, much less impressive without his outer garments, watched them climb aboard. The car proved to be cramped with the four of them — plus Adda’s improvised cocoon and an expansive seat for Mixxax before an array of controls. Mixxax pulled off his hat and veil with every expression of relief. He pulled a lever; the heavy door swung outward.

Just before she was sealed away from the forest, Dura called out: “And Philas! Give them our love…”

The door settled into its frame with a dull impact. Mixxax pulled another lever: a hiss, startlingly loud, erupted from the walls around them.

Air flooded the cabin. It was sweet, invigorating, and it filled Dura’s head — but it was, she reminded herself, alien. She found a corner and huddled into it, pulling her knees to her chest.

Mixxax looked around. He seemed puzzled. “Are you all right? You look — ill.”

Dura fought the urge to lunge at him, to batter at the clear panels of wood set in the walls. “Toba Mixxax, we are Human Beings,” she hissed. “We have never, in our lives, been confined inside a box before. Try to understand how it feels.”

Toba seemed baffled. Then he turned away and, looking self-conscious, hauled on reins that passed through the wooden walls.

Dura’s belly lurched as the car jerked into motion. “Toba. Where is this City of yours?”

“At the South Pole,” he said. “Downflux. As far downflux as it’s possible to go.”

Downflux…

Dura closed her eyes.

Dura emerged reluctantly from sleep.

She could feel the laxness of her muscles, the slow rhythm of her heart, the rich, warm Air of the car pulsing through her lungs and capillaries. She opened her eyecups slowly and glanced around the cramped, boxy interior of the car.

The only light came from four small, clear sections of wall — windows, Mixxax had called them — and the little wooden room was immersed in semi-darkness. It was a bizarre situation: to take a shit, she’d had to open a panel and squat over a tube; when she pulled a little lever the waste had been sucked away into the Air. The cabin itself was constructed of panels of wood fixed to a framework of struts and spars. The frame surrounded her, she thought fancifully, like the rib cage of some immense, protective creature. Still half-asleep, she remembered absently her feelings of threat when first climbing into the car. Now, after less than a day, she felt only a womb-like security; it was astonishing how quickly humans could adjust.

Adda’s stretcher was still secured to the struts to which they had strapped it. Adda himself seemed to be asleep — or rather, unconscious. He breathed noisily, his mouth gaping and dribbling fluid; his eyes were half-open, but even his good eye was a small lake of pus which leaked slowly onto his cheek and forehead; small, harmless symbiotes covered his cheeks, lapping at the pus. Farr was curled, asleep, into a tight ball, wadded into one corner of the boxy cabin; his face was tucked into his knees and his hair waved gently as he breathed.

Mixxax sat in his comfortable-looking seat before his array of levers and gadgets. He had his back to her, his eyes focused on the journey ahead of them. As he sat in his undershorts she could see afresh how thin and bony this man from the City really was, how pale his flesh. But, at this moment, in control of his vehicle, he radiated calm and competence. It was that very calmness, the feeling of being in a controlled, secure environment — coupled with the exhaustion of the abortive hunt, the stress of Adda’s injuries, the thinness of the forest Air — that had lulled Dura and Farr to fall asleep almost instantly, once the car had begun its journey.

Well, Dura was grateful for this brief interlude of peace. Soon enough the pressures of the outside world would return — the responsibilities of Adda’s illness, Farr’s vulnerability and need for protection, the unimaginable strangeness of the place to which they were being taken. Before long she would be looking back on this brief, secure interlude in the confining walls of the car with nostalgic affection.

Unwinding slowly, stretching to get the stiffness out of her muscles, she pushed out of her corner and glided across the small cabin to Mixxax’s seat. She anchored herself by holding on to the back of the chair and peered past him out of his window.

Toba Mixxax gave a start, flinching away from her. Dura had to suppress a laugh at the moment of near-panic on his broad face.

“I’m sorry,” he said quietly. “I thought you were asleep.”

“The others still are, I think. How long was I out?”

He shrugged. “A while.”

She peered out of Mixxax’s window, squinting a little at the golden brightness of the Air. From the front face of the car, leather leaders led to a light wooden framework which constrained the strong young Air-pigs Mixxax called his “team.” The laboring pigs were emitting green clouds of jetfart, so dense they half-obscured the animals themselves; but they were making the car sail along the vortex lines, she saw. Thin leather ropes — reins — were attached to the pierced fins of the pigs and led, through a tight membrane in the front face of the cabin, to Mixxax’s hands; Mixxax held the reins almost casually, as if his control of the pigs and car was unthinking, automatic. Dura fantasized briefly about living in such a place as this magical Parz City, where the ability to direct a car like this came as naturally as Waving.

Her eye followed the tunnel of vortices far ahead of the car to the distinct point where they merged, obscuring infinity. And just beyond that red-white point at infinity she made out the dull glow of the South Pole… and perhaps, she wondered, the glow of Parz City itself.

The Crust sailed over them like an immense ceiling, detail whipping past her with disconcerting speed. The trees through which she had hunted still grew here. They dangled from the diaphanous substance of the Crust and following the Magfield lines like hair-tubes; the cup-shapes of their neutrino leaves sparkled as her view of them shifted. But the trees seemed to be thinning: she discerned patches of Crust separating small, regular-looking stands of trees.

…And the exposed Crust was not bare: rectangular markings coated it, each perhaps a hundred mansheights across. The rectangles were characterized by slight differences of color, varieties of texture. Some contained markings which swept across the patches in the direction of the Magfield like trapped vortex lines, but the patterns in others worked aslant from the Magfield direction — even perpendicular to it. And some bore no markings at all, save for random stipples of deeper color.

She stared into the South. The rectangular enclosures covered the Crust from this point in, she saw, marking it out in a patchwork that receded into the misty infinity beyond the end of the vortex lines. Small forms moved across the enclosures, patiently working: humans, dwarfed by distance and by the scale of the enclosures. Here and there she made out the boxy forms of Air-cars drifting through groups of humans, supervising and inspecting.

She felt humbled, dwarfed. The cap of Crust around the Pole was cultivated — but on an immense scale.

Before this journey she had never seen any artifact larger than the Human Beings’ Net. The car of Toba Mixxax, with its unending complexity, was impressive enough, she supposed — but these markings across the Crust were of another order entirely: artifice on a grand enough scale to challenge the curvature of the Star itself.

And put there by humans, like herself. She fought back awe.

She sought for the words Mixxax had used. “Ceiling-farm,” she recalled at last. “Toba Mixxax, this is your… ceiling-farm.”

He laughed, an edge of bitterness in his voice. “Hardly. These fields are much too lush for the likes of me. No, we passed the borders of my ceiling-farm long ago, while you were sleeping… poor as it is, you probably wouldn’t have been able to distinguish it from the forest. When I picked you up we were about thirty meters from the Pole. We’re within about five meters of Parz now; here the Air is thicker, warmer — the structure of the Star is different, just over the Pole itself — and people can live and work much higher, close to the Crust itself.” He waved a hand, the reins resting casually in his grasp. “We’re getting into the richest arable area. The Crust farms from this point in are owned by much richer folk than me. Or better connected… You wouldn’t think it possible for one man to have as many brothers-in-law as Hork IV. Even worse than his father was. And…”

“What are they doing?”

“Who?”

She pointed to the fields. “The people up there.”

He frowned, apparently surprised by the question. “They’re coolies,” he said. “What I mistook your people for. They’re working the fields.”

“Growing pap for the City,” came a growl from behind them.

Dura turned, startled. Adda was awake; though his pus-filled eyecups were as sightless as before, he held himself a little stiffer in his cocoon of clothes and rope and his mouth was working, bubbles of spittle erupting from its comer.

Dura swam quickly to his side. “I’m sorry we woke you,” she whispered. “How are you feeling?”

His mouth twisted and his throat bubbled, in a ghastly parody of a laugh. “Oh, terrific. What do you think? If you were any better-looking I’d invite you in here to keep me warm.”

She snorted. “Don’t waste your Air on stupid jokes, you old fool.” She tried to adjust the position of his neck, smoothing out rucks in the rolled-up cloth around it.

Each time she touched him he winced.

Toba Mixxax turned. “There’s food in that locker,” he said, pointing. “We’ve still a long way to go.”

In the place he’d indicated there was a small door cut into the wall, fixed by a short leather thong; opening it, Dura found a series of small bowls, each covered by a tight-fitting leather skin.
