The humidity in Frame Room Three always smelled of scalded lard and damp cellulose. It was five past six on a Tuesday, and the overhead steam pipes were clicking their way up to working pressure with a rhythm like a brass clockwork pig being kicked down a gravel road. Arthur Finch hung his tin lunch pail on the brass peg behind the grease locker, right where he had hung it every working morning since the winter of the Great Frost, and wiped his nose on the coarse twill of his sleeve. The peg was worn flat on its top edge by thirty years of similar tin handles, showing the dull yellow zinc beneath the lacquer.

Arthur was forty-two years old, though the spinning floors had given his joints the creaking, measured cadence of sixty. His fingers were broad, scarred with white lateral seams where snapped flyers had bitten into the hide, and his lungs maintained a low, dry flutter like paper rustling in a draft. Next to him, young Billy Vardaman was already untying his apron strings from his neck to retie them around his narrow waist, his skin glistening with the light mist of oil that was the room’s permanent weather.

"He’s brought that Dutch fellow again," Billy said, jerking his chin toward the raised catwalk that hung along the western brickwork. "The one with the spectacles that don't have no ears, just pinch your snout like an owl."

Arthur didn’t look up immediately. Looking up was an apprentice’s mistake; if you looked up, you weren’t looking at the sliver guides, and if an end broke while you were gawking at the gentry, the mule carriage would keep rolling out its twenty yards of clattering iron, and by the time you caught the slack, you’d have twenty pounds of snarled waste cotton wrapped around the tin roller. He spat carefully into the sawdust trough that ran the length of the floor.

"Mr. Van der Weyde," Arthur said. "And they’re called pince-nez. Don't go staring at him, or he'll think you’re short of a job and find you one with a wire brush."

The Dutch engineer was standing beside Master Overseer Crane, their dark broadcloth coats looking oddly stiff against the grey whitewash of the brick walls. Between them, mounted on the central bearing housing where the big leather belt came up through the floor from the steam cellar, sat the new bronze housing they’d spent three Sundays installing behind locked oak doors. Crane called it an "isochronous regulator," which was seven syllables too many for anything that did its work with grease and teeth. To the floor hands, it was simply the Brass Kettle—a ribbed bulb the size of a hogshead, cold as mutton fat when idle, but already whistling through its petcocks with a thin, reedy tone that made the small bones in Arthur’s inner ear feel like they were vibrating in salt water.

The mill bell had stopped clanging five minutes ago, its final iron stroke swallowed by the rising rumble of the lower works. Three floors down, the great horizontal Corliss engine was opening its valve chests to four hundred pounds of dry expansion steam. The oak joists beneath Arthur’s clogs trembled once, settled half an inch into their iron stirrups, and then began the great daily oscillation. It was an eleven-cycle-per-second shudder that every man who worked the mule frames carried in his marrow until he died; if you set a pint of porter on the carriage rail, it would form six distinct concentric ripples that never broke against the glass.

"Check the weights on Frame Seven," Arthur told the boy. "The wet south wind has slackened the cords again. If the back-shaft don't lift the counter-faller clean, we'll have snarls from here to breakfast, and Crane will dock us three pence for every pound of cop waste."

Billy scurried off along the alley between Frames Six and Seven, his bare feet slapping the oily maple boards with the nimble, sideways hop of a dog avoiding hot stones. The mule frames were enormous things, each carriage seventy yards long, carrying twelve hundred steel spindles that spun at nine thousand revolutions a minute while the carriage itself rolled slowly out on its cast-iron tracks, drawing the roving out into fine yarn, then pausing for a second of pure, breathless tension before rolling back in to wind the fresh twist onto the paper tubes. A pair of mules faced each other across a four-foot race like two iron dragons conducting a slow, rhythmic duel, clicking and sighing in alternate measures.

Arthur walked the alley of Number Eight, his palm hovering an inch above the guide rollers, feeling for the cold spot that signaled a dry bearing. Most men listened to the frames with their ears, but after twenty years the screech of two thousand unbushed bevel gears turned your hearing into a grey porridge of mid-frequency whistle; Arthur listened with his heels and his palms. He could feel the heart of a dry spindle two bays away through the floor timbers—a sharp, stinging tick that ran up the hickory sole of his right clog.

Up on the catwalk, the two gentlemen were arguing over a length of paper ribbon. Crane had his silver watch out, holding it flat in his palm like a turnip, while Van der Weyde pointed down at the Brass Kettle with a pair of long, bone-handled dividers.

"It is not an increase in speed we are seeking, Mr. Crane," the Dutchman’s voice drifted down through the steam and the chatter of the gear teeth, high and precise, clipped at the ends like cold lead. "Speed is merely the vulgar measure. It is the absolute identity of the stroke. A yard in Manchester must not merely equal a yard in Leeds; it must be the very same yard, recurring without variation. If the carriage returns upon its track with a discrepancy of less than one-fortieth of an inch per thousand cycles, the momentum does not leave the iron. It accumulates. That is the principle."

"The owners don't give a damn for principles, Heinrich," Crane said, his northern bark cutting under the foreign cadence. "They want eighty-count Egyptian twist that doesn't snap when the weavers throw the pick. If your kettle saves twelve ounces of oil a week on the back-shaft, it pays for its coal. If it doesn't, we’ll take the sledge to it and sell the bronze for scrap."

The Dutchman smiled, a quick parting of grey lips that showed teeth as long and narrow as pumpkin seeds. "The iron will not be broken by sledges, my dear friend. The iron will have forgotten how to yield."

Arthur reached the end of Frame Eight and caught the hand-lever just as the carriage hit the outer buffer springs. The wood gave a dull, greasy thunk against the leather cushions. Twelve hundred steel spindles stopped their travel, spun on their points for three seconds to put the hardening twist into the yarn, and then the faller wire dropped with a sharp metallic snap, pressing the thread down so the winding could begin.

It was an ordinary moment, one he had witnessed twenty thousand times. Yet as the faller dropped, Arthur felt an odd hitch in his chest, the sort of dry hiccup that comes from stepping off a curb in the dark when you thought the stones were level.

The room didn't go quiet—quiet was an impossibility when sixty tons of cast iron were in motion—but the sound changed its texture. The roar of the overhead belts lost its slap. Usually, the great five-ply leather bands that ran from the line shaft down to the driving pulleys had a distinct leather-on-iron hiss, a wet ch-clack, ch-clack where the copper rivets went over the crown of the drum. Now, that sound smoothed out into a flat, unbroken hum, like a horn being blown through an empty water pipe.

Billy was standing at the end of the race on Frame Seven, his arm cocked to throw the drive belt over the loose pulley. He had stopped, his knuckles grey where he gripped the shifter handle.

"Mr. Finch?" the boy called out. He didn't yell; he didn't need to. In the sudden, oiled flatness of the room's sound, his voice carried without the usual struggle against the gear-screech.

"What's to do?" Arthur asked, stepping past the end-standard of the machine.

"The clock on the wall," Billy said, pointing toward the high shelf between the two brick piers where the company had bolted an eight-day dial clock in a round mahogany case.

Arthur looked up. The clock had been there since the room was framed in fifty-two. It had a brass pendulum that swung behind a pane of wavy crown glass, four seconds to the double sweep, sluggish and majestic as an alderman’s belly. The pendulum was still swinging, its wide brass bob catching the yellow gaslight from the burner beside it, but the long minute hand was behaving like an eel in a bucket. It would jump forward two minutes in the space of a single heartbeat, shudder until its tip was a blur against the white enamel face, and then hang motionless for ten long strokes of the mule carriage.

"Slack in the escapement," Arthur muttered, though he knew well enough that an escapement didn't produce that sort of twitching without the weight-cord snapping altogether. "Don't mind the clock, Billy. The clock don't pay your wage. Mind your ends. Look at the seventh tier—you’ve got six slack bobbins riding high."

The boy turned back to his work, but his movements had lost their loose, practiced swagger. He touched the revolving wood of the bobbins with the back of his fingers, his eyes wide and round as greengages.

"They're cold, Mr. Finch."

"Everything’s cold till the room gets up to heat," Arthur said, though he knew the bobbins were never cold after six o’clock. A boxwood spindle spinning in a lignum vitae cup at eight thousand turns produced friction enough to fry an egg within five minutes of the starting whistle; by nine, you couldn't lay a palm on the bolster-rail without leaving a smell of toasted horn.

Arthur reached out and laid his calloused thumb against the bolster of spindle forty-two.

The metal was not merely cool; it was dead. It felt like a beach pebble picked out of a winter surf, so dry and devoid of warmth that the moisture on his skin tried to adhere to the iron. Yet the spindle was turning so fast it appeared as nothing more than a grey smear in the air, its copper cop-bottom whirling with a clean, razor-sharp edge that would have taken a man’s thumbnail off had he strayed an eighth of an inch to the left.

From the platform above, there came the sound of a small, precise impact—like an ivory ball dropping onto a stone hearth.

Van der Weyde had leaned out over the iron railing. He was no longer using his dividers. His hands were tucked deep into his coat pockets, and he was watching the line shaft where it passed through the eastern wall of the mill—the wall that looked out toward the canal basin and the chimney stacks of the dye-house.

"The phase is complete," the Dutchman remarked. He did not raise his voice, yet every man between Frame One and Frame Fourteen heard him with an unnatural clarity, as though the fellow were speaking directly into the crook of their collars. "You see, Mr. Crane? The slippage has reached zero. There is no longer any hysteresis in the mechanical train. The engine below is no longer working against the air."

Crane was not looking at the line shaft. He was looking at his sleeve. A loose white thread of waste cotton had drifted down from the ceiling joists, as it always did in a room where fifteen hundredweights of American uplands were being split into draft every twelve hours. The thread had not landed on his cuff. It hung half an inch above the black wool, suspended in the empty air, trembling with a tiny, frantic vibration that was too fast for the eye to follow, its two frayed ends pointing precisely north and south like the needle of a surveyor’s compass.

"Heinrich," Crane said, his tone low and cautious, the voice of a man who has found an adder under a cabbage leaf. "Tell the fireman to dump the grates."

"The fireman cannot hear you," Van der Weyde replied mildly. "Nor could he shovel the coal if he did. The steam is no longer entering the pipe, my friend. The steam has completed its circle."

Arthur left the alley of Number Eight and walked with heavy, deliberate steps toward the heavy oak door that led to the central stairwell. The door was four inches of solid pitch-pine, bound with strap iron and secured by a latch that weighed eight pounds. It was the only way into Frame Room Three, save for the hoist hatch in the corner that went down to the carding room, and the hatch was bolted from the underside every morning by the warehouse clerk to keep the boys from stealing clean tallow for their hair.

He laid his hand on the latch.

The iron was usually slippery with condensed steam and sweat from the hands of thirty men coming and going. Today, it was dry as a church bone. When he pressed down on the thumb-piece, the iron did not lift. It did not rattle. It had no give in it, no more than if it had been carved from the granite lintel above it.

"Billy," Arthur said, not looking back. "Fetch the short pinch-bar from under the sizing tub."

The boy didn't move. He was standing in the middle of the floor, his head tilted back, staring at the high, arched windows that ran along the north wall.

There were seven windows in the room, each twelve feet high, filled with seventy-two small quarries of greenish cylinder glass held in heavy lead cames. Through them, on any other Tuesday morning, you could see the red brick chimney of the parish waterworks, the smoke from the salt-glaze kilns across the canal, and the grey, greasy light of the Lancashire dawn creeping through the soot.

Now there was nothing through the glass.

It was not dark, like night. It was not white, like a river fog. It was simply the color of an empty slate before the slate-pencil has touched it—a flat, uniform grey that had no depth, no distance, and no surface. A pigeon was perched on the stone sill outside the fourth window. It was not moving. Its wings were half-spread, as though it had been caught in the act of flinching from an owl, but its round, black eye did not blink, and the little down feathers on its grey breast were rigid as carved boxwood in the dead light.

"Fetch the bar," Arthur repeated, his voice dropping into that flat, hard register he used when a new piecer began to cry after getting his fingers pinched in the scroll-cam. "Don't look at the birds, Billy. Go fetch the bar."

The boy turned, his face the color of skimmed milk, and ran for the grease locker.

On the floor between them, the twelve mules continued their march.

Out they went, seventy yards of iron carriages gliding on their polished rails with a smooth, terrifying silence. The wheels did not squeak; the leather buffers did not groan. The cotton came off the wooden skewers in the creels without a single break, twelve thousand ends of thread stretching thinner and thinner, drawing down from the thickness of a candle-wick to the hair-fine diameter of forty-count weft, perfectly even, without a slub, without a knot, without a single speck of leaf or trash.

Arthur took three steps toward the central pillar where the Brass Kettle was bolted to the bearing.

The copper pipes that fed oil to the machine’s journals were no longer dripping. The oil inside the glass sight-glasses was frozen—not into ice, for the room was not cold, but into a clear, golden jelly that had no bubbles in it. Beneath the glass, the brass shaft was turning at three hundred revolutions, its keyway a transparent blur, yet the oil did not stir against the bronze casing. The liquid was ignoring the steel that turned inside it.

"Mr. Van der Weyde," Arthur said, stopping at the foot of the iron ladder that led to the catwalk. His clogs made no sound on the floorboards now; the hickory seemed to meet the maple without that sharp, hollow clap that had echoed through the mill for fifty years. "The door’s jammed fast. The latch won't drop."

The Dutchman looked down through the bronze railing. His pince-nez caught the gaslight, showing two blank discs of yellow reflection where his eyes should have been.

"The latch has not jammed, Mr. Finch," he said, speaking with the patient condescension of a schoolmaster explaining division to an idiot. "The latch is simply no longer in relation with the catch. To open a door, one must have an 'elsewhere' for the door to open into. Surely you understand that much of carpentry?"

Arthur looked at the man’s polished boots, then at the grease on his own knuckles. "I understand that the seven o’clock carters will be at the gate with twelve bales of Sea Island, and if the hoists aren't clear, Mr. Arkwright will have the hide off your back, spectacles or no."

Van der Weyde chuckled. It was a dry, paper-bag sound. "Mr. Arkwright is currently seven million miles away, my good man. Or perhaps seven inches. The distinction has ceased to be mathematically significant. Tell me—have you looked at your roving lately?"

Arthur turned his head toward Frame Four.

A roving frame was simple enough. It was just a rack of wooden bobbins feeding loose, untwisted cotton through three pairs of iron rollers running at different speeds to draw the fibers straight before they went to the mule. The roving itself was fragile stuff, no stronger than a twist of sheep's wool you’d pick off a brier bush; you could blow it in two with a stout breath.

The strand feeding into the first roller of Frame Four had parted.

A piece of raw cotton had caught in the leather fluting of the top roller, snapping the silver thread three inches above the guide wire.

Normally, the loose end would have fallen against the timber frame and wrapped itself into a filthy 'lap' around the bottom iron. But this broken end had not fallen.

It stood straight up in the greasy air, stiff as a knitting needle, its frayed tip pointing toward the center of the Brass Kettle like an iron wire toward a loadstone. As Arthur watched, a second end broke on the frame behind him. It too did not drop; it snapped upward with a faint, musical ping, vibrating for three seconds like a plucked harp-string before freezing into the same rigid, horizontal alignment.

Along the three-hundred-foot length of the room, twelve thousand spindles continued to spin. They did not slow. They did not speed up. The belt from the steam cellar had stopped shuddering; it was flat as a board, rigid as an iron hoop, running over the overhead pulleys without a ripple or a sway.

Billy came back from the locker, his hands empty. He was holding his fingers out before him, staring at them with a foolish, slack-jawed grin.

"The bar wasn't there," the boy whispered. "I reached into the box where we keep the crow and the long cold-chisel, and there weren't no iron in it, Mr. Finch."

"You looked in the wrong locker," Arthur said, though his own hand had gone into his pocket to find his clasp-knife, and his fingers were currently closing around empty space where thirty years of bone-handled Sheffield steel ought to have been.

"No," Billy said, his voice rising toward that thin shriek that boys use when they’re about to bolt into the street. "The box was there. But the inside of it was just... it was the same as the window, Mr. Finch. You put your hand in, and there isn't no bottom to it, and your fingers don't touch no wood, and it don't feel like nothing at all. It don't even feel cold. It just feels like you haven't got no hand until you pull it back out again."

Arthur looked down at his own apron.

A drop of sweat had fallen from his chin. It had stopped two inches above his leather bib. It hung there, a tiny, perfect sphere of grey brine, reflecting the twelve thousand spinning bobbins in its curved surface, steady as a plumb-bob on a windless day.

Up on the walk, Mr. Crane had finally dropped his watch.

The gold turnip fell six inches, stopped dead in mid-air, and began to turn slowly on its stem, its second hand sweeping around the dial with a frantic, chattering speed that sounded like a beetle trapped in a walnut shell.

"Heinrich," Crane whispered, his northern bark entirely gone now, leaving only the thin, dry scrape of an old man whose ledger doesn't balance. "What have you done to the works?"

"I have eliminated the losses," the Dutchman said, his voice smooth as linseed oil. "Every engineer knows that the mule is the most imperfect of all instruments. It wastes ninety percent of its effort in the carriage return, in the friction of the bolsters, in the resistance of the atmosphere to the flyer. It is an insult to the mathematics of God. So I have closed the circuit. Nothing leaves the room, Mr. Crane. Not a foot-pound of work. Not a calorie of heat. Not a single grain of twist."

Arthur reached out and touched the suspended drop of his own sweat with the tip of his finger.

It didn't break. It felt hard, round, and smooth, like a lead bird-shot that had been rubbed with grease. When he pushed it, the drop didn't yield; it moved the whole column of air around it, so that his own shirt-front pulled toward his ribs with a dry, rustling snap.

"Mr. Van der Weyde," Arthur said, his clogs rooted to the maple boards that no longer vibrated beneath him. "If nothing leaves the room, where's the seven o’clock shift going to stand?"

The Dutchman didn't answer. He was watching the first mule carriage reach the end of its seventy-yard draw.

The carriage didn't hit the buffer springs. It didn't stop. It began its return journey toward the roller-beam, but the track beneath it had ceased to be straight. The long line of iron wheels was curving—not much, perhaps half an inch over two hundred feet—bending inward toward the Brass Kettle with the slow, stately dignity of a river finding a new channel through the silt.

Behind it, the twelve hundred strands of cotton didn't wind onto the bobbins. They were hanging between the spindle tips and the delivery rollers in long, catenary curves, white and motionless as salt-glazed wire, while the room around them settled into a silence so dense that Arthur could hear the wax shifting inside his own ears.

The silence that had settled over Frame Room Three did not have the qualities of a natural hush. It was not the quiet of a midnight moor or an empty church, but a heavy, pressurized density that seemed to wedge itself into the throat. Arthur Finch stood by the locked pitch-pine door, his shoulder pressed against the jamb, listening to the lack of sound. Behind him, the seventy-yard carriage of Frame Eight was still gliding inward on its curved path, its wheels turning on the iron tracks without the characteristic metallic click of the rail-joints. The grease on the slides was dry, yet there was no friction screech. It was as if the machinery had been translated into a picture of itself, moving by the sheer momentum of some unseen hand that had forgotten how to let go.

"Arthur," Billy Vardaman whispered, his knuckles white where he held his own apron bib away from his chest. "Arthur, my ears are hot. Like I’ve been diving in the canal after coal-barges and can't get the water out."

"Keep your tongue behind your teeth, Billy," Arthur said, though his own ears were ringing with a high, dry whistle that had no relation to the rumble of the lower mill. He looked down at the lock. The iron casing of the latch was six inches wide, secured to the timber by four heavy wood screws that had been driven home with a hand-brace thirty years ago. The heads of those screws were flush with the rusted plate, but when Arthur leaned closer, he saw that the slots in the iron heads were no longer straight. They had begun to twist, the iron metal flowing like warm treacle under the influence of some slow, spiraling force that seemed to emanate from the floorboards.

"Mr. Crane!" Arthur called out, his voice sounding thin and clipped, as if the air were too thick to let the vowels carry. "We need the wedge from the headstock. This timber’s binding in the rebate."

Crane didn't look down from the catwalk. He was still staring at his gold watch, which hung suspended in the grease-laden air like a small, brass-backed beetle. The chain of the watch—a heavy double-link of Albert plate—had uncoiled itself and was currently floating in three perfect, rigid hoops, each hoop slightly larger than the last, like the brass rings of a parlor game.

"The wood isn't binding, Finch," Crane said. His northern voice had lost its usual gravel; it sounded flat and distant, like a man shouting through a wool-sack. "The wood has no edge to it. Look at the hinge."

Arthur bent down. The heavy strap-hinges were three feet long, bolted through the four-inch pine with carriage bolts. Where the iron met the wood, the sharp, clean line of the carpentry had gone soft. The black pitch-pine was no longer distinct from the black scrap-iron; the two substances had begun to smudge into one another, forming a grey, fibrous transition zone where the grain of the timber seemed to run right through the metal bolts like thread through a needle. When he touched it, his finger didn't meet the cold resistance of iron or the greasy splinter of pine. It met nothing at all—a blank, dry absence that made the skin of his thumb go numb and white for three seconds after he pulled it back.

"Mr. Van der Weyde," Arthur said, turning back toward the raised platform. "The boy says his box is empty. The iron tools are gone. And now the door’s growing into the frame."

The Dutch engineer was leaning over the bronze rail of the catwalk, his spectacles still catching the yellow gas-flare in two flat, unblinking discs. He had taken a small leather-bound notebook from his breast pocket and was writing in it with a silver pencil-case, his fingers moving with a rapid, spider-like agility that seemed entirely unaffected by the room's strange thickening.

"It is not growing, Mr. Finch," Van der Weyde said, without looking up from his column of figures. "Growth is a biological vulgarity. What you are observing is the simplification of the boundary. In a closed system, there is no mathematical utility in maintaining a distinction between 'door' and 'frame.' Both are merely barriers to the escape of momentum. Since the momentum cannot escape, the boundary between them is being smoothed out by the conservation of the field. It is quite beautiful, if you have the geometry to see it."

"I have the geometry of a thirty-shilling-a-week spinner," Arthur said, his clogs making a dry, paper-like rustle as he stepped back toward the center alley. "And that geometry says that if we don't get the six o'clock weft down to the warehouse before the clerk locks his books, we'll all be spending our Sunday in the workhouse."

"The workhouse," Van der Weyde murmured, his pencil making a dry scritch-scritch on the paper, "is currently an infinite number of yards away, Mr. Finch. Or perhaps it is in the next room. But as there is no longer a 'next room' in any sense that your clogs would recognize, I suggest you concern yourself with the tension of the spindles. The yarn must not be allowed to slacken."

"Why shouldn't it slacken?" Billy asked, his voice rising a octave as he crept closer to Arthur's elbow. "It's only cotton, isn't it? It's only eighty-count mule twist."

"Look at the delivery rollers," Arthur told him, pointing a scarred thumb toward Frame Six.

The rollers were three pairs of polished iron cylinders that ran the length of the frame, drawing the loose roving down before the spindle put the twist into it. They were turning—or rather, they appeared to be turning, their brass driving gears showing a continuous, silent rotation of teeth—but the cotton roving that entered them was no longer being drawn. The white sliver of fibers was entering the top roller as a thick, fluffy rope of raw American uplands, and it was emerging from the bottom roller as the same thick, fluffy rope. The draft ratio—the mathematical proportion between the speed of the back roller and the front roller, which determined the fineness of the thread—had ceased to perform its office. The cotton was passing through the iron rollers without being squeezed, without being stretched, and yet it was emerging from the other side as a continuous, unbroken strand of fine, hardened yarn that had already received its full complement of ninety turns to the inch.

"It's spinning itself," Billy whispered, his mouth hanging open so wide that a drop of moisture had gathered at the corner of his lip. "The rollers aren't pinching it, Mr. Finch. The thread's just... growing out of the iron."

"It is not growing," Arthur repeated, using the Dutchman's phrase with a grim, sarcastic weight. "It's being pulled. But there's nothing on the other end to pull it."

He walked down the alley of Frame Six, his eyes fixed on the spindle-points. The twelve hundred steel spindles were still whirling in their copper bolster-cups, but they had ceased to look like individual shafts of metal. The speed had increased—not in terms of revolutions per minute, for the clock on the wall had stopped its twitching and was now hanging with both its hands pointed straight up at twelve—but in terms of definition. The spindles had become twelve hundred grey, transparent columns of mist, each one perfectly circular, through which the red brick of the opposite wall could be seen as clearly as through a pane of well-washed bottle-glass.

Arthur reached out his hand toward the driving pulley of Frame Six.

The leather belt that ran from the line shaft down to the machine's headstock was five inches wide, made of three thicknesses of prime ox-hide sewn together with copper wire. When the machine was running, that belt carried a tension of four hundred pounds, enough to snap a man's arm like a dry hemlock twig if he got his sleeve caught in the intake.

Arthur laid his flat palm against the face of the leather.

There was no heat. There was no vibration. The leather felt like cold, dry linoleum that had been left in a cellar over winter. When he pressed his hand harder against the moving band, the belt did not yield. It did not slip on the iron pulley. His palm remained dry, without a trace of the black oil-grease that usually coated every square inch of the driving gear. He looked at his fingers; they were clean, the skin looking oddly white and dry, as if the natural oils of his own body had been drawn out through his pores by the dry grey air of the room.

"Crane," Arthur said, his voice dropping into that low, level tone he used when the weavers started a turnout over the price of tallow. "Get down here."

The overseer did not move immediately. He was still looking at his suspended watch, which had now stopped its rotation and was hanging perfectly still, three inches above the iron railing of the catwalk. His silver-headed cane, which he usually carried under his arm like a sergeant's swagger-stick, had slipped from his hand. It had not fallen to the floorboards. It was currently standing upright on its brass ferrule in the middle of the air, halfway between the catwalk and the first frame, vibrating with a tiny, frantic shudder that made its silver cap look like a grey, walnut-sized cloud.

"I can't, Arthur," Crane said, his northern accent sounding strangely childish in its flat neutrality. "My feet won't take the steps."

"What do you mean they won't take the steps?"

"They aren't there," Crane said. He reached down and took hold of the cuffs of his trousers, pulling them up three inches to reveal his wool stockings and the tops of his leather boots.

The boots were there, right enough, resting on the iron plate of the catwalk. But the iron plate beneath them had gone transparent. Arthur could see through the three-eighths-inch casting as if it were a sheet of summer ice; he could see the big bevel gears of the vertical shaft below, the teeth locked together in a silent, motionless embrace, and through those gears, he could see the whitewashed ceiling of the carding room on the floor below.

But there was no carding room.

There were no carding engines, no piles of raw cotton laps, no oily floorboards, and no little piecer-boys running between the flats with their tin cans of waste grease. There was only a flat, grey void that had the same slate-like color as the space outside the seven high windows. It was an empty cellar that went down forever, without a joist, without a pillar, and without a bottom.

"The lower works have been disconnected," Van der Weyde said, his silver pencil-case clicking against his teeth as he turned another page in his notebook. "Or, to be more precise, we have been disconnected from them. The line shaft no longer receives its torque from the engine house, Mr. Crane. It receives its torque from the future."

"The future?" Crane barked, though the bark had no teeth in it now. "What's the future got to do with my spinning? The owners want today's twist today, Heinrich. They aren't going to pay for yarn that hasn't been spun yet."

"They have already paid for it," the Dutchman said, with his dry, paper-bag chuckle. "They paid for it when they bought this mill. They bought forty thousand square yards of Lancashire earth, three steam boilers, and the lives of sixty men for thirty years. They bought the momentum. Now the momentum has stopped losing itself in the friction of the brickwork. It is concentrating. Every revolution of the spindle that has ever occurred in this room, and every revolution that ever will occur, is now happening in the same instant. The yarn is being wound onto the bobbins because the bobbins have already been wound. It is a closed loop, my friends. The thread has no beginning, and it has no end. It is the perfect selvage."

Arthur Finch walked back to Frame Seven, where Billy Vardaman was sitting on the floor with his knees pulled up to his chin, his eyes fixed on the sawdust trough.

"Billy," Arthur said, crouching down beside the boy. "Give me your knife."

"I haven't got one, Mr. Finch," Billy whispered. "I told you. The locker was empty. The iron's all gone."

"You've got your pocket-knife," Arthur said, reaching out to touch the small, greasy pocket in the side of the boy's fustian trousers. "The one with the horn handle you used for trimming the bobbins. The one your uncle gave you."

Billy hesitated, then slid his hand into his pocket. He pulled it out again, his fingers curled around a small, oblong object.

It was not a knife.

It was a piece of grey, fine-grained stone, about three inches long, shaped like a pocket-knife but completely solid, without a blade, without a bolster, and without a hinge. The horn handle had been smoothed out into the stone, its dark brown mottling still visible as a faint, watery pattern beneath the grey surface of the slate.

"It's gone cold," Billy said, holding it out on his open palm. "It feels like a bit of the canal bridge, Mr. Finch."

Arthur took the stone knife. It had the weight of iron, but when he drew his thumb across the place where the blade should have opened, his skin did not feel the edge. The stone was perfectly continuous, a single, undivided piece of matter that had forgotten how to be three different materials—horn, brass, and steel—and had settled instead into the simplest form of solid it could find.

"The simplifications are accelerating," Van der Weyde called down from the catwalk. He had laid his notebook on the railing and was now leaning over, his pince-nez hanging by their black silk cord, swinging in small, perfectly circular arcs that did not slow down. "You see, Mr. Finch? The complexity of the universe is an expensive luxury. It requires an enormous expenditure of thermodynamic energy to keep iron distinct from wood, or wood from bone. When the system is sealed, and the energy can no longer escape into the surrounding ether, the system begins to economize. It discards the unnecessary details. It reduces the number of variables. In another hour, there will be only three things in this room: the spinner, the spindle, and the thread."

"And what about us?" Arthur asked, looking up at the two men on the platform. "Where do we go when the details are gone?"

"We are the details, Mr. Finch," the Dutchman said, his grey lips parting in that pumpkin-seed smile. "We are the friction that the machine is trying to eliminate. But do not be discouraged. A good spinner is always useful, even in an empty room. You will simply have to learn to spin without the cotton."

Arthur stood up, his joints making that dry, cracking sound that always reminded him of old willow-wood. He walked to the center of the room, where the Brass Kettle was bolted to the central bearing housing.

The ribbed bulb of the regulator was no longer whistling. The petcocks were still open, their brass levers turned to the "purge" position, but no steam was coming through the vents. Instead, the air around the brass ribbing was shimmering with a faint, purple light—not the bright violet of an electric spark, but the dull, greasy purple of wet coal-tar on a rainy road. This light did not cast any shadows on the white-washed wall behind it; it seemed to absorb the yellow gaslight from the burners, drawing the illumination into itself until the gas-flares looked like nothing more than thin, orange threads hanging from the iron pipes.

Arthur reached out his hand toward the ribbed bronze casing of the Kettle.

"Arthur, don't!" Crane shouted from above, his voice finally showing a touch of its old, supervisory authority. "That's company property! If you crack that bronze, Arkwright will have the police on you before the boilers are cold!"

"The boilers are already cold, Mr. Crane," Arthur said.

He laid his palm flat against the ribbed bronze of the regulator.

The metal did not burn him. It did not freeze him. It felt like nothing at all—not because it was empty, but because it was too full. When his skin touched the bronze, his mind was suddenly filled with the sound of ten thousand looms—not just the twelve frames in Frame Room Three, but every loom that had ever clattered in the valley of the Irwell, every hand-loom that had ever clicked in the weavers' garrets of Bolton, and every great iron power-loom that was currently shaking the foundations of the Manchester mills. It was a single, monstrous, rhythmic roar that had no gaps in it, no pauses for the shuttle-return, and no stops for the broken ends.

And in the middle of that roar, Arthur could hear his own heart.

It was beating at sixty-six strokes a minute, its steady, double-thump the only irregular sound in the whole room. But as he held his hand against the Kettle, the beat began to change. It didn't speed up. It didn't slow down. It began to synchronize itself with the great eleven-cycle shudder of the floorboards—the long, slow vibration that had been running through the oak joists since fifty-two.

He tried to pull his hand back, but his fingers had gone soft.

The skin of his palm had begun to merge with the bronze ribs of the regulator, the white scars of his old flyer-burns turning into fine, copper-colored lines that ran right down into the metal casting. He could feel the cold oil inside the sight-glasses running through the veins of his wrist, its golden, bubble-free grease lubricating his pulse until his hand felt as slick and frictionless as the main-shaft of the Corliss engine.

"Billy," Arthur said, his voice sounding so deep and resonant now that it seemed to vibrate the sawdust in the troughs. "Get the grease-can."

"The grease-can's gone, Mr. Finch," the boy said, his voice coming from somewhere near the floor, though Arthur could no longer see him through the purple haze that was rising from the machine. "Everything's gone grey. I can't see my feet, Arthur. I can't see my own apron."

"The apron is an unnecessary complication," Van der Weyde's voice drifted down, thin as a spider-thread, yet perfectly clear in the purple gloom. "It was designed to protect your clothing from the oil. Since there is no longer any oil to stain you, and no clothing to be protected, the apron has been discarded. It is a very simple calculation, you see. The system is merely clearing its accounts."

Arthur gave a long, slow pull with his shoulder.

The wood of his clogs didn't slide on the floor; it didn't creak. But with a dry, sucking sound, like a boot coming out of a peat-bog, his hand came away from the bronze casing.

The palm was no longer pink. It was a dull, polished yellow-brown, the color of old bell-metal, and when he tapped his knuckles against the iron rail of the nearest frame, they made a clear, musical ting that vibrated through the steel of the carriage for ten seconds after the touch.

"Mr. Crane," Arthur said, looking up at the catwalk where the two figures were now nothing more than two dark, vertical cylinders against the grey whitewash. "We've got to stop the carriages. If they reach the end of the track while the curves are still growing, they'll run into each other, and we'll have sixty tons of scrap-iron in the middle of the floor."

"They won't run into each other, Finch," Crane said. His voice was very faint now, like the whistle of wind through a keyhole. "They've forgotten how to collide. They're just... passing through."

Arthur looked at Frame Seven.

The carriage of Frame Seven had reached the end of its seventy-yard draw. It was supposed to stop, wait for three seconds while the spindles put the final twist into the yarn, and then return.

It didn't stop.

The long iron beam, carrying its twelve hundred spinning spindles, rolled right through the timber end-standard of Frame Eight. The two machines didn't crash; there was no screech of tearing iron or splintering wood. The twelve hundred steel spindles of Frame Seven passed clean through the twelve hundred steel spindles of Frame Eight, their grey, transparent mists mingling for a single, breathless second like two puffs of tobacco-smoke in a draft, before they emerged on the other side, each carriage continuing its silent, rhythmic march as if the other had been nothing more than a shadow on the wall.

But the cotton yarn between them had not passed through.

Where the two frames had intersected, the twenty-four hundred strands of fine Egyptian twist had knotted themselves together. It was not a common knot—not the weavers' knot or the spinners' splice that Arthur had tied with his thumb ten thousand times. It was a flat, white, intricate web that had no loose ends, no beginning, and no exit. The threads ran from the bobbins of Frame Seven to the spindles of Frame Eight, then back again, forming a dense, diagonal mesh that looked like a sheet of fine lace that had been frozen in the middle of a wind-storm.

As Arthur watched, the first thread in the mesh began to vibrate.

It didn't make a sound—the air was too thick for sound now—but it began to glow with that same flat, purple light that was coming from the Brass Kettle. The vibration ran along the thread like a spark along a fuse, reaching the bobbin-creel, where the wooden skewers began to turn in their brass sockets with a new, frantic velocity.

"The pattern is expanding," Van der Weyde said. He had dropped his notebook now. His two dark hands were flat against the iron rail of the catwalk, and he was leaning so far forward that his forehead was almost touching the suspended watch. "The thread is no longer merely carrying the tension of the spindle, Mr. Crane. It is carrying the tension of the space between them. If the web continues to weave itself at this rate, the room will be completely filled before the next shift is called."

"Filled with what?" Crane asked.

"With the warp," the Dutchman said. "The warp of the room itself. It is weaving the floorboards into the ceiling, my friend. It is weaving your watch into your waistcoat. It is writing the whole history of the mill into a single yard of ninety-count twist."

Arthur Finch walked to the end of Frame Eight.

He looked at the web of purple thread that was growing between the two machines. It was beautiful, in a dry, cold way that made his teeth ache. The lines of the cotton were so straight, so perfect, that they didn't look like anything that had ever grown in a Georgia field or been picked by human hands. They looked like the ruled lines in a schoolmaster's geometry book, recurring without a single error, without a single slub, and without a single break.

He reached out his metal-colored hand and took hold of the first thread in the web.

The cotton was cold—colder than the spindle-bolsters, colder than the stone knife in Billy's pocket. It felt like a thin wire of solid ice that had been rubbed with paraffin. When he pulled on it, the thread didn't yield. It didn't snap. But he could feel the tension running right through his fingers, up his forearm, and into his shoulder, where his collarbone gave a dry, metallic tick as it settled into its new, simplified relationship with his ribs.

"Billy," Arthur said, his eyes fixed on the center of the web. "Help me pull."

"I can't, Arthur," the boy's voice came from somewhere near his knees. "I'm... I'm getting too thin. I don't think I've got enough wood in me to pull on a thread like that."

Arthur looked down.

Billy Vardaman was still there, but he had lost his outline. He looked like a grey charcoal sketch of a boy, drawn on the slate-grey background of the room with a few hasty, smudged lines. His bare feet had disappeared altogether; they had merged into the maple boards of the floor, so that his ankles seemed to grow directly out of the timber like two grey willow-stumps.

"You've got enough in you, Billy," Arthur said, his voice sounding like a church bell being struck with a lead hammer. "You're a spinner's boy. You've got the grease in your marrow. Now get hold of the thread."

The boy hesitated, then reached out his grey, smudged hand.

When his fingers closed around the purple cotton, they didn't merge with it. For a single, flickering second, the shape of his hand became clear again—the five knuckles, the broken nail on his index finger, the white scar where he'd been pinched by the scroll-cam. The cotton thread seemed to give him back his definition, drawing his outlines out of the grey void and pinning them to the iron frame like a specimen in a glass box.

"It's hard, Arthur," Billy whispered, his teeth chattering with a sound like dry bobbins in a basket. "It's hard as a rail."

"Pull," Arthur said.

They pulled together.

The web did not break, but the room around them gave a great, silent heave—the sort of slow, sickening roll that a canal-boat makes when it enters the deep water of the lock. The high, arched windows on the north wall didn't shatter, but the seventy-two small quarries of greenish glass began to slide out of their lead cames, falling down toward the stone sills like sheets of grey oil that had been frozen into squares.

Outside, the pigeon was still there.

But it was no longer a pigeon.

It had been simplified. Its feathers had gone, its round black eye had gone, and its beak had smoothed out into the grey stone of the sill. It was now nothing more than a small, oblong lump of grey granite, shaped like a bird in flight, but rooted to the stone beneath it with a perfect, seamless joint that had no beginning and no end.

"Look!" Billy cried, pointing with his free hand toward the eastern wall.

The line shaft, which had been turning in its wall-box since fifty-two, had finally stopped its silent rotation. The three-inch iron bar had gone transparent, its keyway showing a faint, purple spiral that ran right through the brickwork toward the canal basin outside.

But the canal basin was no longer there.

Through the hole where the line shaft passed, Arthur could see nothing but the same slate-grey void, flat and uniform, except for a single, thin line of white cotton thread that ran from the end of the shaft out into the empty space, stretching away toward the horizon like a surveyor's line across a plowed field.

"The line is complete," Van der Weyde's voice came down, so faint now that it was almost nothing more than the dry rustle of paper in a draft. "The thread has reached the boundary. Now we must see if the knot will hold."

"It'll hold," Arthur Finch said, his metal-coated fingers locking around the cold purple wire of the web. "It'll hold because there's nothing else in the world to break it."

He looked at the Brass Kettle, which was now glowing with a light so bright it made his yellow-disc eyes watering. The twelve frames continued their march, their carriages passing through one another with a rhythmic, silent grace that had no relation to the work of human hands, while the great web of cotton thread between them grew thicker, tighter, and more perfect with every return of the carriage.
