September 1: The Dory's Edge

The gunwale took the gray chop sideways, throwing a sheet of freezing spray over my knees. Captain Teague did not turn his head to look at me, nor did he shift his pipe from the left corner of his mouth, where it stayed clenched like a black tooth. He kept his eyes fixed entirely on the white finger rising out of the water four miles off the mainland shore. Heron Rock looked less like an island and more like an anvil dropped from heaven and left to drown.

Two miles of open water lay behind us, churned into iron-colored foam by an east-northeast draft that had been rising since dawn. Between my boots sat two wooden trunks banded with hoop iron, a sack of dry meal, half a barrel of salt pork, and a crate containing forty pounds of paraffin candles and tallow soap. On paper, signed by the district inspector in Portland, I was the newly appointed assistant to Mr. Enoch Vane, though the town constable who saw me off at the slip had spat into the kelp and murmured that anyone volunteering to share six acres of ledge with Enoch Vane was either running from a debt or looking for an easy place to lose his wits.

I gripped the wet thwarts until the pine bit into my palms. The dory rose on a long groundswell, hung there in the thin September light, and plunged down into the trough with a slap that set the grease in the pork barrel rattling. Up ahead, the ledge grew edges. It was not stone like the pasture rocks back in Kennebec County, which slept under moss and sweetfern; this granite had been broken sharp, cut with black fissures where the weeds hung limp and sodden like drowned hair.

"Keep your legs loose when we touch," Teague shouted above the surge, his voice flat as dry timber. "The surge here does not wait for a man to find his boots. When I say jump, jump toward the iron ladder, not the rock. You miss the rung and the undertow will drag you into the crack under the boat slip before I can get an oar out to fish you up."

The white tower sat upon the highest hump of the stone, eighty feet of cold brick painted with lead wash, its lantern gallery ringed by an iron railing no thicker than a pencil from down in the chop. Below it, tucked into a depression like an egg in a nest, was the keeper’s dwelling: a low-roofed box of granite blocks with two chimneys, four small windows facing south, and a heavy hemlock door bolted against the Atlantic. No smoke lifted from the chimneys. A single gull drifted over the lightning rod atop the lantern dome, stalled against the wind, and slid sideways down the air.

The dory surged into the narrow gut between the ledge and an outlying tooth of stone the charts called the Calf. The water here turned green and violent, boiling over submerged shelves of weed. Teague threw his weight against the starboard oar, swung the stern into the backwash, and brought the bow within two feet of an iron ladder bolted directly into the granite face. Rust ran down the stone from every bolt like dried blood.

"Go," Teague said.

I did not think about the Kennebec valleys, nor the clerk’s desk in Bath I had abandoned, nor the small grave behind the churchyard in Phippsburg where Martha lay under two years of clover. I threw my body forward, caught the third rung with both wool mittens, and felt the Atlantic bite through my boots as my heels dragged through the rising swell before my arms hauled my dead weight up into the wind.

The Inventory on the Slip

The winch rattled on its dry cedar frame. Enoch Vane stood at the top of the slipways, winding the greasy cable with slow, methodical strokes of his forearm. He was sixty years old, perhaps seventy, shaped like a sack of oats tied in the middle with a piece of tarred twine, his face cured by woodsmoke and salt into the color of an old boot left out in the grass. He wore a pea-jacket missing three horn buttons, and around his neck was a strip of gray flannel pinned with a brass safety needle.

He did not offer a hand as I hauled myself over the lip of the timber staging. He did not ask my name, though the district letter had preceded me by three weeks on the tender Amethyst. He simply reached out with a steel hook, snagged the line attached to my lower sea-chest, and dragged it across the planks toward the oil house without looking back.

"Wind’s hauling east," he said to the boards between his feet. "Get the meal inside before the salt-damp gets into the weave. If the flour goes gray, you’ll eat the crusts yourself. The government doesn't pay for weevily shorts."

Together, using a wooden hand-barrow, we carried the supplies up the forty-four steps cut into the living ledge. The path was slick with bird-lime and a thin skin of dried dulse. To the east, the ocean stretched away unbroken toward Ireland, flat and heavy under a sky that looked like a bruised tin plate. To the west, the coast of Maine was nothing more than a dark blue smudge along the water’s edge, separated from us by three miles of gray chop and the white breakers of the outer bar.

Inside the entry room of the keeper's house, the air smelled of three things: damp plaster, parsnips, and whale oil that had leaked through flooring and dried ten years ago. It was a cold that had nothing to do with frost; it was the cold of stone that had stood in the shade of the sea since the creation of the world, never warmed by an open hearth for long enough to drive the well-water out of the mortar.

Vane took a stub of carpenter's pencil from his waistcoat and walked around the floor, pointing with the lead at the items listed on the inventory card nailed beside the pantry door:

One iron cookstove, two-hole, cast at Bangor, 1851.
Two iron pots, one cracked at the rim, serviceable.
One spruce table, scrubbed with lye.
Two chairs of birch, one with three ash spindles replaced by hazel twigs.
One copper tea-kettle, dented by an axe-handle.
One tallow lamp for the kitchen table.
One copy of the Regulations for the Lighthouse Service, 1868, bound in sheep.
One Bible, octavo, printed at Boston, with the flyleaf torn away.
One bucket of lime for the privy behind the oil house.

"The government gives you two quarts of vinegar every six months to keep the scurvy out of your gums," Vane said, turning his small, rheumy eyes upon me for the first time. "I don't use it. Tastes like copper nails. You can have mine if your teeth get loose. But don't go splashing it on the table. The vinegar eats the grain out of the pine, and the inspector down from Rockland will run his thumb over the boards to see if we’ve been scouring them with sand."

He pointed to a steep flight of ladder-stairs tucked behind the pantry.

"Your bed is the one under the eaves on the south side. The tick is filled with marsh hay from the mainland, cut two seasons back. If you find mice in the corners, don't kill them with the broom. Throw them into the rain-butt. If you smash them against the lath, the smell stays until November."

The Architecture of Heron Rock

The whole world here is two hundred paces long by seventy paces wide at low water. When the tide comes full on the new moon, the Atlantic takes back forty paces of the weed-ledge, and the Calf disappears entirely under five feet of green surf, leaving only a white boiling where the rocks tear the bellies out of the waves.

The tower stands at the center like a surveyor’s peg. It is eight-sided outside, circular within, built of heavy blocks of granite hauled out from the quarries at Vinalhaven forty years ago. Between the outer wall and the inner core of brick lies an air space four inches wide, intended to carry off the condensation that gathers when the ocean air meets the warm chimney-draft of the lamps. But the draft does not carry it off; it collects on the inside of the stone and runs down into the iron staircase in long, brown dribbles that taste of sulfur and lime.

A man cannot walk three steps on this rock without climbing or descending. From the water’s edge to the kitchen door is thirty feet of ascent over granite steps worn smooth by the nails of keepers’ shoes. From the kitchen door to the oil-room is twenty paces across a flagged court where no weed can take root because Vane pours the spent lye-water from his washing tubs between the cracks every Saturday morning. From the oil-room, an enclosed gallery of wood leads directly into the belly of the tower.

Inside the base of the light, the darkness smells of iron rust and paraffin. The stairs begin there: ninety-six cast-iron risers, spiraling round a central shaft of hollow brick through which the sash-weights of the clockwork mechanism drop like lead pendulums. Every tenth step has a small iron landing with an open diamond pattern that lets the cold air rush up from the cellar below. When the wind comes round to the southeast, the draft through those open diamonds makes a sound like a man blowing into an empty cider jug.

Up on the top landing, just beneath the lantern floor, sits the watch-room. It contains an iron stove no bigger than an eight-quart bucket, an oak desk with a slanted lid, a tall stool without a back, and the clock. The clock was made by a man named Willard in Boston; it has an eight-day movement and a brass face that has been rubbed with chalk until the numerals are faint as watermarks on linen. It ticks with a heavy, double clack that sounds louder than the sea when the water is calm.

Above that is the light itself.

I stood on the watch-room ladder and stuck my head up through the copper trapdoor into the lantern room at four in the afternoon. The sun had broken through the cloud-bank to the west, laying a flat, copper glare across the gray reach of water between us and the coast. The light filled the glass octagon until my eyes ached. There, hung upon its iron rollers, was the great glass bee-hive: hundreds of prisms of pure, pale-green flint-glass, set in heavy brass ribs that rose toward the copper roof like the ribs of an upturned schooner.

In the center sat the lamp, its four concentric wicks dry and white, smelling faintly of the sperm oil that still saturated the copper feed-tubes. It was silent up there. The wind, which had been rattling the shingles of the dwelling below, was nothing more than a smooth, hard pressure against the heavy plate-glass panes, three-eighths of an inch thick, which protected the lens from the hawks and the gales.

"Don't touch the brass," Vane's voice came from the ladder below me. His boots scraped the rungs with a dry, hollow sound. "You've got grease on your thumbs from the pork barrel. Salt and pig-fat will turn that brass black before tomorrow's breakfast. A keeper doesn't touch the metal without his linen gloves on, not even if the tower is falling down around his ears."

He pushed past me, his head barely clearing my shoulder. From his pocket he took a square of clean cotton rag and rubbed the iron handrail where my bare skin had rested for five seconds.

"The government doesn't buy brass for us to look at," he muttered, his face turned toward the sea. "They buy it so the ships can see it five leagues off Monhegan. You see that line of white out yonder? That's the Roaring Bull. If a vessel takes the Bull on her port quarter because our light was smoky by half an inch, the bodies don't wash ashore at Bath or Rockland. They wash up right here, into the gut by the Calf, and it's the keeper that has to sew them into canvas and wait for the coroner's dory to come out from the Reach."

He turned the brass key in the regulator. The clockwork gave a small, greasy whirr, then settled into its rhythm: one drop of the balance every three seconds, steady as the pulse in a dying horse’s neck.

First Night Watch

The sunset did not last. It went out like a coal dropped in a bucket of ditch-water, leaving only a dirty purple smear along the western hills. The east turned black an hour before the lamps were lit.

My watch began at eight bells—midnight by the Willard clock—but Vane had me in the watch-room by half-past seven to see the lighting. We stood in our stocking feet on the lantern floor, having left our grease-stained shoes on the landing below to keep the grit from scratching the plate glass. The air in the lantern had turned cold enough to show our breath, but the moment Vane struck the lucifer match against the sand-paper box, the smell changed. The sulfur flare was followed instantly by the thick, sweetish, heavy reek of sperm oil drawn up through four rounds of cotton braid.

He touched the match to the innermost wick, waited for the blue line of fire to run the circle, then touched the second, the third, and the fourth. The flame rose yellow and smoky until he took the brass crank and adjusted the air draft from the cellar vents. The yellow fire went white—a hard, solid core of light that made my eyes water and cast our two shadows across the sea like black spokes turning through the dark.

"Now," Vane said, sitting on the high stool in the watch-room with his hands flat on his knees. "The light turns once every two minutes. If the clock stops, you don't call me. You take the iron lever from behind the desk and you turn the table by hand until the gear catches again. You keep your eye on the second-hand of the Willard. If she's three seconds fast, let her run; if she's four seconds slow, wind the cable up two turns. But don't you let that beam stand still. If an iron-boat from Boston sees a fixed light where a flash should be, she'll steer south to clear the Bull and fetch up directly on the northern reef."

He went down the stairs, his socks padding softly on the cast-iron plates until the trapdoor thumped shut behind him.

The watch-room was six paces wide. The wall was painted white lead over brick, three coats deep, so hard and cold that if I leaned my shoulder against it, the chill went through my flannel shirt and my wool waistcoat like a wet spade through garden turf. On the desk lay the Logbook: a wide, flat folio covered in blue sail-cloth, its pages ruled with red margins and printed with headings for wind, barometer, sky, oil consumed, and occurrences.

The entry for the day was already written in Vane's small, crabbed hand, which looked like the scratches made by a crow in wet snow:

Sept. 1. Wind ENE, fresh. Sea rough. Tender Amethyst did not appear. Capt. Teague brought mail and new assistant, J. Finch, late of Phippsburg. Delivered: 1 bbl. pork, 1 bag meal, 2 gals. vinegar. Light lit at 6:42. Oil drawn: 3 pints, 1 gill. A vessel seen standing south at sunset, three-masted schooner, deep laden. All well.

I sat on the stool and took the quill between my fingers, but there was nothing to add. The government did not provide ink for a man's thoughts. It provided ink for the level of the oil in the brass cistern, the height of the mercury in the glass tube, and the condition of the spare chimneys in their straw crates under the bench.

Outside the eight-sided cage of glass, the night was as black as the bottom of an iron kettle. I could not see the water, though I could hear it. It did not sound like the waves on the sandy beaches at Small Point, which came in with a long, tumbling roar that died out in a hiss of foam; here the sea had nothing to break against but vertical rock, and each swell struck the base of the tower with a heavy, subterranean thump that made the floor under my stool shiver like a struck bell.

Every two minutes the flash went out across the water—a broad, white road of light that reached three leagues into the darkness, touched the gray crest of a wave for half a second, showed the white water boiling over the Roaring Bull, and then vanished, leaving the dark three times blacker than before.

At two in the morning, a flock of small birds hit the lantern panes.

There was no warning: just a series of soft, wet thuds against the glass, like someone throwing handfuls of mud against a parlor window. I stood up so fast the stool tipped against the desk with a clatter. Outside the glass, drawn by the fierce glare of the wicks, dozens of tiny gray shapes fluttered like moths, their wings beating against the thick plate with a dry, papery rattle.

One of them struck the center pane directly in front of the lens, dropped down onto the narrow copper scupper outside, and lay there with its wings spread flat. It was a yellow-throated warbler, no larger than my thumb, its green-and-gold feathers plastered to its small breast by the sea-mist that was beginning to drift in from the south. Its beak was open, a tiny needle of black horn, and its dark eyes were already glazed by the salt-frost.

I reached for the iron catch of the storm window to draw the bird inside, but remembered Vane’s rule: Never open the glass while the lamps are hot. A draft of cold salt air would crack a three-hundred-dollar prism from edge to center before the sash could be latched again.

I stood there with my hand on the brass stay and watched the small thing slide slowly down the copper gutter as the wind rose, until a sudden gust lifted it by the wing-coverts and whirled it out into the dark, down toward the Calf and the long, white surge that never slept.

The Salt in the Well

At sunrise, the light must be extinguished before the upper rim of the sun clears the red spruce trees on the mainland hills. That is the first rule in the sheep-bound book: The keeper shall be as frugal with the oil of the department as if it were his own substance.

I blew out the wicks through a brass tube shaped like an ear-trumpet, turning the screws down until the cotton braids disappeared into the oil-wells with a low sizzle. Then came the curtains. Heavy brown holland blinds, weighted with lead sinkers, had to be hung around the entire inside of the lantern room to keep the morning sun from focusing through the lenses onto the central burner. If the sun struck those flint-glass prisms while the lamp was cold, they would act like a burning-glass and melt the copper feed-tubes into a puddle of red slag before noon.

Down in the kitchen, Vane had already set the tea-kettle on the iron stove. The fire was made of hemlock bark and driftwood knots he had hauled out of the crevices at the low-water mark with an iron crook. It burned with a greenish flame that smelled of brine and wet pitch.

"You left the draft open three notches too wide," he said, without turning around from the skillet where two salt-herrings were curling into gray ribbons of skin. "I could hear the flue whistling from my bunk. You burned four gills more oil than we used last Michaelmas."

"The wind came around south," I said, my voice dry from the tallow smoke and the four hours of watching. "The mist was thick enough to hide the Calf by three bells."

"The mist don't drink the oil," he said, turning a herring over with the point of an iron file he had ground into a knife. "The wicks drink it. You keep the wicks high because you're scared of the dark. Every clerk from the mainland does the same. They come out here with their coats brushed and their paper collars on, and the first time a petrel hits the glass they think the devil has come to take them by the hair, and they screw the wicks up until the iron dome gets cherry-red."

He poured two mugs of black tea from the copper kettle. The water was brown as cedar-water from a swamp, with a pale scum of white froth floating around the rim.

I took a swallow and nearly choked. It tasted like iron rust and salt marsh.

"The tank's low," Vane said, sitting down and breaking a ship-biscuit between his thumbs with a sound like a dry branch snapping. "We haven't had a good three-day rain since the first week of August. What's in the cistern now is the drainage from the roofs after that dry northeast blow two weeks back. The wind blew two barrels of salt spray onto the shingles, and the next morning a half-inch shower washed the whole mess down the leader into the cellar tank. It won't kill you. It loosens the bowels for three days, then your belly gets hard as a hemlock plank and you don't notice it no more."

He pushed the plate of dry biscuit toward me.

"Teague won't be back until the first week of October with the root-cellar load," he said, chewing slowly with his side teeth, his jaw working like a cow's. "If the sea gets up before then, he won't come at all until the November freeze. You got three sisters in Phippsburg, the paper says."

"Two," I said. "Both married to smiths."

"They won't come out here," he said. "Nobody comes out here except the tender, and the tender only comes when the inspector wants to see if we've been stealing the turpentine. You got six shirts?"

"Four," I said.

"That's two too many," he said. "The salt rots the linen whether you wear it or leave it in the chest. You might as well cut two of them into lamp-rags now. The government sends us old flannel for the lenses, but the flannel is full of lime from the wash-houses and leaves lint on the prisms. Pure linen is the only thing that doesn't leave a trail on the flint."

He finished his herring, wiped his knife on the leg of his trousers, and stood up to take the brass oil-gauge from the wall.

"Come along," he said. "The sun's up over the spruce. We got twenty-four lamps in the lower cellar to trim before the tide turns, and the brass on the clock needs the rottenstone."

I followed him out the low door into the morning.

The sun was up, but it had no heat in it. It lay across the stone like a thin wash of yellow varnish, showing every crack and weed-cleft in the rock. Out on the Roaring Bull, three seals were lying on the black weed, their wet skins shining like greasy coal as the long Atlantic swells rose and fell, never pausing, never breaking their stride, licking the iron ladder on the boat-slip with a cold, rhythmic slap that sounded as if the island were being hollowed out from beneath, one mouthful of granite at a time.

The Keeper's Desk: Rules and Memoranda

The following lines were pasted into the back of the station logbook, written in ink that had faded to the color of dry tobacco leaves, dated June 12, 1854:

1. The assistant shall obey the keeper in all things lawful pertaining to the maintenance of the light and the preservation of the property of the United States.
2. No spirituous liquors shall be kept upon the station under penalty of instant dismissal by the district superintendent.
3. The light shall be shown from the going down of the sun to the rising of the same, without regard to fog, snow, or tempest.
4. If the keeper die, the assistant shall not leave the rock to carry news of the same, but shall remain at his post until relieved by the dory from the mainland or the arrival of the tender.
5. The dead shall be laid in the coal-cellar beneath the oil house, wrapped in their own bedding, until such time as the sea permits a boat to land.

Under these, someone—perhaps Vane, perhaps the man who died of the quinsy out here the winter before the war—had written with a pencil:

The wind blows from the east forty days in the fall. The water in the tank smells of dead shingle-bugs. God have mercy on the assistant.

I shut the book, turned the heavy iron key in the desk lock, and took the copper oil-can by its bail to begin the long climb back down to the stone.

September 8: The Vault Beneath the Flagstones

The oil house was not a house at all, but a low vault of hammered ashlar sunk into the ledge fifty feet north of the tower, half-buried under sod and sea-gravel to keep the temperature even through the dog days and the January freeze. To enter it, a man had to duck his head beneath a lintel of rough-faced granite that wept continuous salt-sweat onto his neck, lift an oak latch greased with mutton tallow, and pull open a door sheathed in tinned iron to frustrate the harbor rats.

Inside, the darkness was dense, cool, and nearly unbreathable. It carried the heavy, cloying stench of fifty casks of winter-strained spermaceti oil, mixed with the sharp stink of spirits of turpentine, dried bladder-wrack, and the sour lime washing off the masonry. Down here, thirty paces from the boiling surf, the swell did not roar; it vibrated through the floorboards like an iron bar struck against an anvil deep under the bedrock.

Vane set his tin lantern on a wall-bracket lined with sheet zinc and pointed a stubby, blackened thumb at the rows of tierces resting upon heavy hemlock skids. Each cask was strapped with six hoops of strap iron, white with bloom where the sea-air had begun to pit the metal, and sealed at the bung with red wax stamped with the seal of the Lighthouse Board.

"The government pays two dollars and forty cents a gallon for the winter-strained," Vane said, his voice flat in the stone cellar. "Every drop that comes through that bung has to clear four layers of linen before it goes up the stairs to the cistern. If a grain of sand or a spider's leg gets into the burner, the draft gutters, the wick crusts over, and by two in the morning the lamp is throwing a red smear across the water instead of a white spark. You think you know how to pour oil because you filled a glass lamp on a parlor table in Phippsburg. You don't know nothing about it. A parlor lamp burns kerosene and smokes like a ditch fire; this here is refined from the heads of bull sperm whales taken off the Western Islands, and it requires more nursing than a sick heifer."

He dragged a five-gallon copper oil-carrier across the flagstones. The vessel had an arched bail, an iron handle, and a long, tapering snout capped with a brass screw-plug. The copper had been scoured with sand until it was the pale, soft color of a dried apricot, entirely free of verdigris.

"Now take the spigot," Vane told me, handing over a heavy wooden tap and an ash mallet. "Mind the red wax. We chip the seal into the bucket, not onto the stone. The inspector counts the wax chips when the tender comes back in the spring. If the count don't match the casks emptied, he marks the difference out of our quarter's pay, and I have no desire to buy five gallons of whale grease out of my sixty dollars because your fingers were too clumsy to save the wax."

I knelt before the lowest cask, my knees sinking into the damp canvas sack Vane had laid over the flags to keep the salt-damp from rotting our trousers. The bung-hole was stubborn. When the oak tap finally went home under the flat face of the mallet, the wood groaned, and a thick, buttery stream of pale yellow fat began to coil into the funnel. It ran silent and slow, like cold honey drawn from a comb in November.

The cold in that cellar was different from the clean bite of the wind on the rocks outside. It settled into the marrow of my shins within ten minutes, smelling of old slaughter, of blubber-boilers in New Bedford, and of dark sea-creatures hauled out of three miles of blue water to be boiled down into grease for two men living on an offshore ledge.

The Mechanics of the Concentric Wick

Up in the watch-room, with the morning sun beating hard against the holland curtains until the air smelled like an iron foundry, the daily task of trimming began. It was not a matter of simply snipping a blackened edge with household shears. The lamp of a second-order Fresnel lens was an intricate brass engine consisting of four nested, circular wicks made of woven cotton braid, set into concentric collars of red brass with less than a line of clearance between them.

Vane took his seat on the tall backless stool, his spectacles tied behind his ears with a piece of dirty sail-twine, and laid out his kit upon the baize-covered bench: three pairs of curved scissors with brass guide-plates, an ivory-handled probe for teasing the fibers, a box of emery powder, and a roll of white cotton wicking imported from Manchester.

"Look here," he said, turning the brass elevation-pinion until the four circles of charred cotton rose an eighth of an inch above the brass burner-tubes. "You see that black crust? That's what six hours of flame leaves behind. It's not soot. It's coke. It's the carbon left over from the fat that couldn't find enough air to burn clean. If you leave a crust no thicker than the skin of an onion on the outer ring, the air will curl inward, chill the center burner, and the whole flame will go yellow by midnight."

He took the shears—curved like the beak of a curlew, with an adjustable brass lip that rode along the rim of the burner—and made three quick, circular passes. The blades hissed through the stiffened cotton, dropping four neat ribbons of black cinder into a brass tray placed beneath the burner.

"The cut must be dead level," he murmured, not looking up, his breath puffing into his gray mustache. "Not a hair higher on the east than on the west. If you leave a point standing half a line above the rest, that point becomes a torch. It drinks more oil than the cotton can lift, it starts to smoke, the smoke hits the silvered dome overhead, and in twenty minutes you've got five dollars' worth of soot baked onto the parabolic reflectors."

He handed me the second pair of shears and pointed to the spare burner sitting in its wooden cradle on the corner of the bench.

"You cut the spare," he said. "Take your time. If you hack the cotton, you'll unseat the whole wick from its brass rack, and then we spend two hours with the lead-wire drawing a new ring through the feeder. And don't breathe on the brass. The salt in your breath turns the lacquer green, and green lacquer don't pass the district officer."

I took the shears. The tool felt cold and heavy in my fingers, vastly more delicate than any implement I had handled in the timber yards of Bath. I leaned close to the burner, resting the flat brass guide against the outer lip of the metal collar, and brought the edges together.

The cotton gave way with a dry, papery crunch. My hand trembled slightly from the long carry up the ninety-six spiral steps with the five-gallon carrier, and the blade dipped a fraction of an inch too low on the seaward side.

Vane didn't raise his voice. He merely reached out with the tip of his ivory probe, touched the tiny valley my cut had made in the cotton circle, and made a dry sound in the back of his throat like a gull clearing a fish-bone.

"Now you've done it," he said. "That valley will draw the flame down into the tube. In half an hour, the oil in the reservoir would boil, catch back down the line, and blow the glass chimney into fifty pieces. Strip it. Take the rack out and wind a new length from the bolt."

I sat in the heat behind the drawn curtains, the smell of whale grease clinging to the skin of my forearms, and began the tedious work of unscrewing the concentric brass rings with a jeweler's screwdriver. Every screw was numbered with a punch-mark: one dot for the north, two for the east, three for the south, four for the west. It took forty minutes of patient coaxing to thread the new white cotton tape through the narrow brass slots without tearing the woven edge or twisting the braid.

Vane watched me without speaking, his thumbs tucked into his waistcoat pockets, rocking on his heels with the slow, pendulous motion of a man who had spent thirty years watching a pendulum swing.

"A clerk thinks everything is written down with ink," he said at last, when my fingers were white from pressing the stubborn cotton against the brass teeth. "He thinks if he writes 'lighted at sunset' in the blue book, the light will go on burning because the law says it must. The law don't keep the flame round, Finch. A drop of sweat on that wick will split the light just as sure as a squall splits a rotten mainsail. The light lives on clean cotton, level brass, and oil that's had the tallow strained out of it by three frosts."

The Science of the Cistern

Beneath the watch-room deck sat the supply cistern, a vessel of heavy sheet iron holding fifty gallons, connected to the burner above by a system of red-copper tubes fitted with weighted valves. This was the moderator mechanism, an intricate clockwork pump designed to lift the heavy whale oil from the reservoir below the lens up to the wick-tubes at a rate faster than the cotton could consume it.

The overflow was intentional; it cooled the brass tubes so the metal would not expand and bind the wick-slides, running back down through a fine mesh strainer into the sump to be drawn up and pumped again.

"The clockwork for the pump runs on a twelve-pound lead weight," Vane explained, opening the small iron door in the pedestal of the lens. Inside, a drum wound with brass wire showed four rows of heavy brass gear-teeth, bright and greasy with neat's-foot oil. "Every four hours, you wind the winch twenty-two turns. Not twenty-one, not twenty-three. Twenty-one leaves the oil starved at the fourth wick; twenty-three jams the ratchet against the stop-dog, and then you have to climb under the table with an iron punch to loose the pawl."

He took a clean rag—a square cut from one of my own linen shirts, sacrificed that morning to the station's needs—and wiped down the gear-teeth one by one.

"The old lamps," he said, "the ones they had before the war, were nothing but argand burners set on a hoop, with tin reflectors shaped like wash-basins behind them. A keeper could go to sleep for two hours and find them still sputtering when he woke. But this Frenchman's machine—this Fresnel business—is an ungodly thing. It gathers every ray of light that leaves the wick and bends it out across the water until a man in a skiff three leagues off can read a newspaper by it. But it won't abide dirt, and it won't abide neglect."

He looked at me over the rims of his glasses, his pale blue eyes watery behind the thick lenses.

"If the pump stops while you're below getting tea, the wicks burn down into the brass in eight minutes. In ten minutes, the brass tubes solder themselves together with their own melting-lead. If that happens, you and I won't have to wait for the tender to bring us our discharge papers; we can just take our boots in our hands and walk off the slip into the surf, because the government will have our hides on the barn door at Portland before the week is out."

He handed me the winding crank. The iron was polished smooth by the palms of six keepers before me, cold to the touch and heavy as a ship's capstan-bar.

I fitted the square socket over the winding arbor. The winch turned with a heavy, rhythmic click-clack-click, the lead weight rising slowly inside its wooden casing through the floor of the watch-room. At the twentieth turn, the tension grew stiff; at the twenty-second, the iron dog dropped into its notch with a sharp ping that echoed up into the copper ventilator above our heads.

"Now," Vane said, pulling a brass stop-cock on the feed-pipe. "Look at the saucer."

Down through the copper pipe came the first flow of oil, driven by the steady descent of the lead weight. It welled up through the center of the concentric tubes like spring-water through sand, flooding the freshly trimmed white wicks until the cotton turned from ivory to a deep, translucent amber. The oil did not spill over the lip; it hung there, rounded and trembling, held by the surface tension of the heavy animal fat, then broke into four neat streams that trickled down the copper return-channels into the lower strainer.

"That's the feed," Vane muttered, with what passed for satisfaction on his leathery face. "Four gills an hour, steady as a falling stone. Now you take the spirits and the rouge-powder and you clean the reflectors on the landward side. There isn't supposed to be a speck of grease on the silver when the lantern is trimmed for the evening watch."

The Daily Polish

Cleaning the light was an act of penance that lasted four hours every morning. The salt in the air had a way of creeping through the seams of the glass cage, leaving a cloudy deposit on the hundreds of polished faces of the lens. If this film was not scrubbed off daily with spirits of wine and dry cotton waste, it attracted moisture, and the moisture baked into a white, chalky crust under the four-hundred-degree heat of the central lamp.

The work had to be done from the inside out. I climbed onto a small, three-legged ladder that curved to fit the inner circumference of the glass cage, carrying a box lined with green baize that held our cleaning tools: three camel-hair brushes, two cakes of Spanish whiting, a flask of pure alcohol, and four pieces of soft chamois skin that had been washed twenty times in soft rainwater to remove any remaining salt.

"Don't you drop that alcohol," Vane shouted from the watch-room deck below. He was sitting at the desk, his spectacles pushed up into his gray hair, peeling a cold potato with his thumb-knife. "The government allows us two quarts of spirits a month for the flint-glass. If you spill it, you'll clean those prisms with vinegar and sea-water, and sea-water will etch the lead-glass until it looks like ground salt."

The air inside the great beehive was close and stifling. The sun, climbing high toward the south, turned each prism into an individual lens that focused a narrow, brilliant pencil of white fire onto my clothes and hands as I worked. I had to drape myself in a gray linen smock to keep the concentrated rays from scorching the wool of my shirt.

I dipped the corner of a chamois into the alcohol and touched the highest ring of prisms—the catadioptric elements that caught the light escaping toward the clouds and turned it back toward the horizon.

The glass was cold and hard beneath my fingers, entirely different from the common window-panes I had known in Bath. It was heavy, brilliant flint, two inches thick at the core, cast with such perfection that when the spirits evaporated from its surface, the glass seemed to vanish entirely, leaving only the dark iron frame suspended in the glare of the noon sky.

Every prism had to be wiped three times: first with the spirit to lift the oil-film, then with the dry linen to clear the haze, and finally with the chamois dusted with a pinch of whiting to bring up the deep, greasy polish that gave the lens its power.

My arms grew numb from working above my head. The smell of the alcohol, evaporating instantly in the sun-warmed air, made my eyes sting and my throat dry. Outside the glass, the sea lay spread out like an expanse of crumpled sheet-lead, three hundred feet below the soles of my stockinged feet. A brig, light-loaded and high in the water, was beating north along the coast, her sails bleached white by the noon glare. She was far off—five miles at least—but through the prisms of the lens her image appeared suddenly distorted, magnified into a monstrous, disjointed shape that seemed to hover fifty feet above the water, its topmasts twisted into golden hoops by the curvature of the glass.

"She's out of Portland," Vane called up, his voice hollow through the iron trapdoor. "Lumber-carrier. If he knew what was good for him, he'd give the Bull a wider berth. The ebb is setting him down toward the ledge half a knot faster than his canvas can carry him off."

I didn't answer. I was rubbing the fourteenth prism of the third ring, my thumb following the sharp, chamfered edge where the glass met the brass retaining-bar. The metal was cool, but the glass was warm from the sun. Between the two lay a thin line of red-lead putty, dry and brittle with age. A flake of it, no bigger than a caraway seed, broke loose under my cloth and fell into the interior of the lens.

I froze, my hand suspended on the ladder.

"What dropped?" Vane asked immediately. He had not looked up from his potato, but his ear was tuned to the iron tower like a musician's to a fiddle.

"A chip of putty," I said, my voice tight. "From the outer rib."

"Get it," he said, without a change in his tone. "If it falls into the oil-saucer, it gets under the valve. If it stays on the carriage-roller, it flats the wheel. Find it before you touch another piece of glass."

I climbed down the rungs on my knees, searching the iron floor with my bare palms until I felt the hard, irregular edge of the lead crumb. It was small enough to have blown away in a sneeze, but when I held it out to Vane, he took it between his thick fingers and examined it with the gravity of a magistrate inspecting a forged bank-note.

"The stone-work shakes," he said, tossing the crumb into the stove-box. "Every time the sea strikes the base at high-water, the iron rings shiver. In forty years, the putty has dried out until it's nothing but chalk and red powder. Next summer the district will have to send the glazier out from Boston to re-bed the whole assembly. But until he comes, you watch the ribs. You see a seam starting to weep, you take the wax-pot and you seal it before the salt gets between the glass and the iron."

The Night-Oil Measure

By four in the afternoon, the cleaning was finished, the holland blinds were checked, and the supply-can was filled for the long watch ahead. The process was governed by a printed chart pasted to the inside lid of the blue logbook, which gave the precise quantity of sperm oil required for each night of the year, calculated to the minute according to the latitude of Heron Rock:

September 8: Sun sets 6:14. Sun rises 5:31. Duration of light: 11 hours, 17 minutes. Consumption authorized: 1 gallon, 3 quarts, 1 pint, 2 gills.

Vane stood over the measure with a tin quart-pot in his hand, his eye leveled with the scratched copper rim. The oil was measured out from the big carrier into a square tin vessel called the night-can, which had a lockable brass cap and a glass gauge-tube running down its side to show the level within.

"The winter oil is heavier than the summer," he said, tilting the pot with a steady wrist. "If the night turns cold, the oil thickens in the feed-tubes, and you have to set the chimney-draft half a notch wider to let the heat from the burner warm the reservoir. But you don't do that until the mercury drops below forty. If you warm the oil too early, it turns thin as water, floods the wicks, and runs down into the ash-pan in a dirty puddle that will catch fire the first time you drop a match."

He locked the night-can with a brass key he carried on an iron ring around his neck, along with the key to the medicine chest and the key to the dead-letter box.

"There's your allowance," he said, setting the can on the desk. "If you burn more than that before sunrise, you'll explain it to the inspector yourself when he comes to verify the quarterly vouchers. He doesn't take 'fog' for an answer, and he doesn't take 'high wind.' The government calculates that a gallon of winter-strained will produce eighty candle-hours of light if the keeper does his duty and the cotton is kept level. If the light goes out before the sun clears the mainland trees, it's because the keeper was sleeping on his stool or let the wicks smoke themselves into charcoal."

He took his pea-jacket from the peg by the door and checked the tin of lucifer matches in his pocket.

"The wind's coming round into the north-northwest," he said, turning toward the ladder. "That means the draft will be sharp tonight. Keep the lower vents closed on the windward side, or you'll have the flame jumping like an alder fire in a brush-heap. And don't you touch the Willard clock. She's running two seconds slow to the twenty-four hours, but that's because the damp has swollen the wooden pendulum-rod. When the northwest wind dries the case out, she'll come back to time on her own."

He disappeared down the trapdoor, leaving me alone with the Willard clock, the blue folio, and the square night-can sitting on the oak desk like an iron idol waiting for its evening sacrifice.

The Second Watch: Midnight to Dawn

At eight bells—midnight—I relieved Vane at the light. He had been sitting on the stool for five hours, his hands resting on his knees, his chin sunk into the dirty gray flannel around his throat. He did not speak when I came up the iron ladder, but merely stood up, took his tin watch from his waistcoat, held it against the Willard to check the balance, and pointed to the brass chimney.

"The second ring is smoking a hair," he said, his voice husky from the heat. "Tease the outer wick down half a line with the wire. She's drinking oil faster than she needs."

He padded down the iron plates without another word, his stockinged feet making no more sound than two dry sheepskins dragged across the floor.

I took the high stool and settled my boots on the iron cross-bar. The tower was silent except for three distinct sounds that never varied: the slow, measured tick-tack of the Willard's heavy brass pallet, the low, steady hiss of the four concentric flames burning inside their cylinder of clear flint-glass, and the subterranean thud of the groundswell striking the outer ledge of Heron Rock.

The air in the lantern room was eighty degrees, while outside the glass the north-northwest wind was scouring the granite at forty-five. The contrast caused a steady river of cold air to pour down the inside of the plate-glass panes, pooling around my ankles on the diamond-pattern iron floor until my feet were numb, even while my face and hands were dry and parched from the fierce heat of the central burner.

Every half-hour, I rose from the stool to perform the ritual.

First, the inspection of the wicks: I peered through a square of dark-green glass held before my eyes, studying the circular crown of flame. It stood four inches high, a hollow cylinder of dazzling white fire that showed not a speck of red along its rim, steady as the tip of an iron spear. The draft through the glass chimney made a dry, hollow roar like wind blowing across the mouth of a cannon.

Second, the winding of the clockwork: I took the heavy crank, fitted it to the winding drum, and lifted the twelve-pound lead weight through its twenty-two turns. The wire cable creaked on the cedar drum, the copper pump-rods gave their greasy shudder, and the oil in the saucer rose a sixteenth of an inch, clear and pale, before falling back through the return-channel.

Third, the walk around the gallery: I unlatched the heavy storm-door that led out onto the narrow iron balcony encircling the lantern, stepped through the copper sill, and pulled the door shut behind me.

The wind took the breath out of my mouth instantly. It was coming straight down from the Camden Hills, dry and cold, smelling of balsam fir and inland granite, stripped of all sea-mist by sixty miles of spruce woods. The ocean below was a wilderness of black troughs and white crests, running fast toward the southeast, boiling with short, angry seas that tore themselves to pieces against the northern teeth of the rock.

The light reached far over the water. It was not a beam such as a lantern throws on a country road; it was a solid wall of white radiance, eight feet high and three miles long, that wheeled slowly around the horizon like a great, glowing spoke of an invisible wheel. Where it passed, the black water turned for a single heartbeat into boiling silver, showing the white backs of the rollers and the long, streaming ribbons of kelp clinging to the Calf. Then the darkness closed back in behind it, three times thicker than before, until the next flash came round to sweep the sea again.

Looking out into that void, I could understand why the old keepers went queer in their heads after three winters on the ledges. A man could sit on the iron stool until he forgot the sound of horses' hooves, the look of plowed earth, and the color of women's hair. He became nothing more than an attachment to the wicks—an eye to watch the second-hand, an arm to wind the lead weight, a thumb to pinch the charred cotton from the brass ring. The light did not belong to him; he belonged to the light, as completely as the copper tubes and the flint-glass prisms.

At two in the morning, a large moth, its wings mottled brown and gray like a piece of birch-bark, fluttered out of the darkness and struck the outer glass of the lantern. It did not drop. The pressure of the north wind held it pinned flat against the three-eighths-inch plate, directly in the focal center of the northern prism.

Through the thickness of the glass, magnified twenty times by the catadioptric rings, I could see every detail of its small body: the delicate feathering of its antennae, the gray down on its thorax, and the large, compound eyes that glowed in the concentrated beam like two tiny coals of red copper. It stayed there for twenty minutes, shivering with the vibration of the tower, while the great white wall of light poured through its wings and out across the empty water toward the coast.

Then a stronger gust came down from the Camden hills, peeled the thing from the glass, and whirled it away into the dark, south toward the Roaring Bull and the long reach of the Atlantic, where there was neither stone to rest upon nor wick to burn.

Dawn and the Balance-Sheet

At half-past five, the eastern sky began to peel open like a fresh-split cod, revealing a narrow streak of watery gray along the edge of the sea. The mainland hills were still buried in purple shadow, but the white spire of the church at Thomaston caught the first ray of the sun while the water below was still as black as spruce beer.

I took the brass ear-trumpet from its hook, turned the regulating screws down until the wicks sank into their brass housings, and blew three sharp, dry breaths into the chimney draft.

The white light vanished. In its place came the foul, heavy smudge of spent oil—a greasy, yellowish smoke that rose toward the copper ventilator in long, ropy wreaths that made me cough into the sleeve of my smock. The flint-glass prisms, which had looked so fierce and alive through the twelve hours of darkness, became suddenly dead and pale, nothing more than cold, heavy blocks of glass set in yellow metal that needed polishing.

I climbed the ladder, drew the brown holland blinds, and dropped the lead weights into their sockets to shield the lens from the morning sun.

Down in the watch-room, the Willard clock was still ticking its slow, double stroke: sixty-one, sixty-two, sixty-three.

I unlocked the blue folio, dipped the iron pen into the stone ink-bottle, and laid my forearm across the ruled page. My fingers were black from the wick-coke and smelled of whale fat—a smell that had already soaked into the grain of my skin so deeply that three washings with tallow soap had failed to loosen it.

The logbook page lay before me, demanding the arithmetic of the night:

Sept. 9. Wind NNW, moderate to fresh. Sky clear. Light shown: 11 hrs. 17 min. Clockwork: wound three times, running true. Oil drawn: 1 gal. 3 qts. 1 pt. 1 gill. Oil remaining in night-can: 1 gill, good measure. Glass clean. Reflectors wiped. No vessels seen within hail. Assistant J. Finch on watch.

I blotted the ink with a pinch of dry sand from the wooden pot, shook the excess back through the horn funnel, and closed the blue cover.

From the kitchen below came the iron rattle of the stove-lid being dropped back into its seat, followed by the dry, hard scrape of Vane's boots against the flagged floor as he went to fetch the morning kettle. Another day had begun on Heron Rock; seventy paces of gray granite were coming up out of the tide, the seals were hauling themselves onto the weed-ledges by the Calf, and down in the dark vault beneath the flagstones, forty-nine casks of winter-strained spermaceti oil were waiting to be carried up the stairs, two pints at a time, to feed the fire that never went out.
