  We started dying before the snow and, like the snow, we continued to fall. It was surprising there were so many of us left to die.

  chapter 1

  1991

  On the evening before the first snow fell, he saw a large bird frozen in the waters of the Hudson River. He knew it must have been a goose or a heron, but he decided that it was a crane. Its neck was tucked under its wingpit and the head was submerged in the river. He peered down at the water’s surface and imagined the ancient ornamental beak. The bird’s legs were spread out and one wing was uncurled as if it had been attempting to fly through ice.

  Treefrog found some bricks at the edge of the path that ran along the waterfront, lifted them high, and flung them down around the bird. The first brick bounced and skidded on the ice, but the second broke the surface and animated the crane for just a moment. The wings skipped minutely. The neck moved in a stiff, majestic arc and the head emerged from under the water, gray and bloated. He rained the bricks down with ferocious intent until the bird was free to move beyond the ice to where the river flowed.

  Tipping his sunglasses up on his forehead, Treefrog watched the bird float away. He knew it would sink to the sands of the Hudson or get frozen in the ice once more, but he turned his back and walked away through the empty park. He kicked at some litter, touched the icy bark of a crab-apple tree, reached the tunnel entrance, and removed both his overcoats. He squeezed his way into a gap in the iron gate and crawled through.

  The tunnel was wide and dark and familiar. There was no sound. Treefrog walked along the railway tracks until he came to a large concrete column. He touched the column with both hands and waited a moment for his eyes to adjust; then he grabbed onto a handhold and, with spectacular strength, hauled himself up. He walked along the beam with perfect balance, reached another catwalk, and shunted himself upward once more.

  In his dark nest, high in the tunnel, Treefrog lit a small fire of twigs and newspaper. It was late evening. A train rumbled in the distance.

  A few pellets of ratshit had collected on the bedside table, and he swept them off before opening the table drawer. From the depths of the drawer Treefrog took out a small purple jewelry bag, undid the yellow string. For a moment he warmed the harmonica in his gloved fist above the fire. He put it to his mouth, tested its warmth, and pulled in a net of tunnel air. The Hohner slipped along his lips. His tongue flickered in against the reeds, and the tendons in his neck shone. He felt the music was breathing him, asserting itself through him. A vision of his daughter whipped up—she was there, she was listening, she was part of his music, she sat with her knees tucked up to her chest and rocked back and forth in childish ecstasy—and he thought once again of the frozen crane in the river.

  Sitting there, in his nest, in the miasmic dark, Treefrog played, transforming the air, giving back to the tunnels their original music.

  chapter 2

  1916

  They arrive at dawn in their geography of hats. A dark field of figures, stalks in motion, bending toward the docklands.

  Scattered at first in the streets of Brooklyn—they have come by trolley and ferry and elevated train—they begin to gather together in a wave. Hard men, diligent in the smoking of cigarettes, they stamp yesterday’s mud from their boots as they walk. A trail of muck is left in the snow. Ice puddles are cracked by the weight of their feet. The cold inveigles itself into their bodies. Some of the men have big mustaches that move like prairie grasses above their lips. Others are young and raw from razors. All of them have faces hollowed by the gravity of their work; they smoke furiously, with the knowledge of those who might be dead in just a few hours. Hunching down into their overcoats, they can perhaps still smell last night on their bodies—they might have been drunk or they might have been making love or they might have been both at once. Later they will laugh at these stories of drink and love, but for now they are silent. It is far too cold to do anything but walk and smoke. They move toward the East River and cluster near the tunnel entrance, stamping their boots on the cobblestones for warmth.

  The snow turns to slush at their feet.

  When the whistle calls the sandhogs to work, they take a last pull on their cigarettes. The red tops of the butts flare and are dropped to the ground, one by one, as if swarms of fireflies are laying themselves down to rest.

  In the middle of the line, Nathan Walker watches as men from the nighttime shift emerge from the tunnel, mucked head to toe, exhausted. Walker realizes that he is looking at his future, so he doesn’t stare too closely, but every now and then his hand stretches out and slaps a finished man’s shoulder. The weary man raises his head, nods, lurches on.

  Walker resists the urge to sneeze. He knows that to have a cold means losing a day’s pay—his nose or his ears might leak blood in the compressed air beneath the river. If a cold is telegraphed, the foreman will pull him out from the crowd. So Walker sucks his coughing and his sneezing down into his stomach. He takes an amulet from his pocket, a piece of stone, and rolls it around in his fingers. The good-luck charm is icy to the touch.

  Walker whispers to his partner, Con O’Leary. “What say, bud?”

  “Sick as a small hospital. A hangover to beat the band.”

  “Me too.”

  “Sweet Jaysus, it’s cold though,” says O’Leary.

  “Ain’t it just?”

  “Heads up, son, here we go.”

  The foreman nods at the two sandhogs, and they join the group at the mouth of the shaft. They stand close together and inch forward. Walker hears the whine of the compression machine from underground. It’s a long hard high sound that will soon become nothing in his ears; the river is a grabber of sound, taking it, swallowing it. Walker adjusts his hat and gives a last look out over the distance. Across the river the three-arch customs house is gray in the morning; longshoremen are busy at the docks; a couple of cargo ships are negotiating floes of ice; out on the water, a young woman in a bright red coat stands on the deck of a ferryboat, waving her arms back and forth. Walker recognizes her as Maura O’Leary; just before he disappears from view her husband, Con, touches his hat in a gesture that could be dismissal or boredom but is in fact love.

  Walker grins at the sight, lowers his head, and begins his descent beneath the river toward another day’s digging on this, a morning so cold that even his heart feels frozen to the wall of his chest.

  * * *

  In the manlock, the door is closed tight and air hisses in around the sandhogs.

  Walker opens the top button of his overcoat. He can feel his toes loosening now in the hot pressurized air. A bead of sweat forms on his brow, and he flicks it aw
ay with his thumb. Beside him, O’Leary stands slumped against the wall, breathing deeply. The two are soon joined by Sean Power and Rhubarb Vannucci. The air grows torrid as the pressure rises. It is as if a heat wave has decided to accompany them underground during winter. The four men hold their noses until their ears begin to pop.

  After a few minutes, Power crouches down and takes a deck of cards from his dungarees. The men search in their pockets for coins and play hog poker while the air compresses their bodies to thirty-two pounds per square inch. Walker wins the first round, and Power slaps the young black man on the shoulder.

  “Look at you, hey, the king of spades!”

  But Walker takes no offense. He knows there is a democracy beneath the river. In the darkness every man’s blood runs the same color—a dago the same as a nigger the same as a Polack the same as a mick—so Walker just laughs, puts the winnings in his pocket, and deals the second hand.

  * * *

  Out of the manlock, still in their hats, the sandhogs enter the compressed air of the tunnel. More than one hundred of them, they slosh through the mud. Waterboys and welders, carpenters and grouters, hoist runners and electricians, they remove their caps and overcoats in the heat. Some have tattoos, others have potbellies, a few are emaciated, most are sinewy. Nearly all of them have worked as miners before—in Colorado, Pennsylvania, New Jersey, Poland, Germany, England—with legacies of blackening lungs to prove it. If they could reach down into their throats they could chisel out diseases from their lungs. The tar and the filth would come away in their fingertips. They could hold a piece of flue-colored tissue and say, This is what the tunnels have done to me.

  There have been many deaths in the tunnel, but there’s a law the sandhogs accept: you live as long as you do until you don’t.

  Bare electric bulbs flicker, and the men move through a liquidy light, casting fiddleback shadows on the walls. The shadows melt and skirt and coalesce, growing longer and then shorter. In the middle of the tunnel runs a thin rail line, which will later be used for transporting equipment and mud. The men step along the tracks, and at various points they leave the convoy. Metal lunch boxes are thrown to the ground. Rosary beads are produced from pockets. The men remove their shirts in the temporary exuberance of beginning work. Here, the closure of a fist to show up an arm muscle. There, the pullback of shoulders to reveal a massive chest. Behind, the thumping sound of a fist into a palm.

  But the four muckers—Walker, O’Leary, Vannucci, and Power—don’t stop to talk. They have to walk the full length of the tunnel, under the cast-iron rings, past machinery and vises and bolts and giant wrenches and stacked bags of Portland cement. Walker goes out in front, balancing on one of the metal rails, while the three others place their feet carefully on the wooden ties. Their shovels swing down by their legs. Walker’s has his name carved into the shaft, O’Leary’s has a bent metal lip, Power’s has toweling wrapped around the handle, and Vannucci’s, once minutely cracked, is held together with a metal sleeve. They continue along, right into the belly of blackness.

  “Hotter than a whore’s kitchen today,” says Power.

  “Ain’t that the truth?”

  “Ever been in a whore’s kitchen?”

  “Only for breakfast,” says Walker. “Grits and eggs over easy.”

  “I swear! Listen to the youngster!”

  “And a little sizzling bacon.”

  “Whooeee, I like that.”

  “Backside bacon. With a little on the rind.”

  “Now we’re talking!”

  At the head of the tunnel they reach the Greathead Shield, the last safety precaution, a giant piece of metal that is pushed through the river by hydraulic jacks. If there is an accident, the shield will hold the mud back like a lid on a cylinder. But the four men must go even further. They each take a deep breath and then stoop to enter the door in the shield. It is like entering a tiny room at the end of the world: seventy-five square feet, all darkness and damp and danger. Here, the riverbed is propped up with long breast boards and huge metal jacks. Above the men’s heads a steel ceiling juts out to protect them from falling rock and sliding mud. Right in front of their eyes hangs a wire-caged bulb, revealing mounds of dirt and puddles of filthy water. The bulb has a pulse to it, the electricity not constant. Sloshing through the water on the floor of the room, Nathan Walker and Con O’Leary reach out and touch the planks for good luck.

  “Touch wood, buddyblue.”

  “I’m touching,” says O’Leary.

  “Goddamn, even the planks done got warm.”

  By the end of the day the muck behind the planks will be gone, carted out on the narrow railway track, loaded on carriages, and pulled by wheezing draft horses to a dump site in Brooklyn. Then the Greathead Shield will be pushed forward once more. Silently, the men challenge themselves to penetrate the riverbed further than ever before, maybe even twelve feet if they’re lucky. They set up a platform to stand on. Walker unwinds a jack and Vannucci takes down two breast boards to create a window for their shoveling. Power and O’Leary step back and get ready to load the mud. The four will swap places throughout the day, shoveling and loading, loading and shoveling, slashing their shovels into the soil, burying the metal edges deep.

  * * *

  Nathan Walker will later sit shivering in the hospital lock and say to his friends, “If only them other guys knew how to talk American, nothing bad woulda happened, nothing at all, not a damn thing.”

  * * *

  He is the best of them, even though he’s only nineteen years old. The work is brutal, but Walker is always the first to begin digging and the last to finish.

  Tall and muscular, he sends ripples along his arm with just one movement of the shovel. He drenches his skin in sweat. The other riverdiggers envy his fluidity, the way the shovel seems to meld with his whole torso, the quiet mastery of his burrowing, the blade making repeated ellipses in the air: one, two, three, strike, return. He stands wide-footed on the platform, wearing blue overalls ripped at the knees, his red hat sideways on his head, a string sewn into the brim so he can tie it under his chin. Every ten seconds the oozy muck comes out from between the breast boards at hip level. Walker turns up shells as he digs, and he rubs them clean with his fingers. He would like to find a slice of bone, an arrowhead, or a piece of petrified wood, but he never does. Sometimes he imagines plants growing down there, yellow jasmine and magnolias and huckleberry bushes. The edges of the Okefenokee swamp come back to him in waves, murky brown waters that pile into the Suwanee of his home.

  Walker has been digging for two years. He arrived on a train from Georgia, the steam whistle ringing high and shrill in his ears.

  The steel shield extends above his head, but much of the time he has to go beyond the shield where there’s no protection. None of the men wear helmets, and all that’s left is just them and river soil.

  Walker takes off his shirt and digs bare-chested.

  Only the river’s muck is cool against his skin, and at times he smears it on his body, over his dark chest and ribs. It feels good to the touch, and soon he is filthy from head to toe.

  He knows that at any moment an avalanche of muck and water could sweep the men backward. They could drown with the East River going down their throats, strange fish and odd rocks in their bellies. The water could pin them against the Greathead Shield while the alarm sounds—a frantic rat tat tat tat of tools on steel—while the men further back in the tunnel scramble toward safety. Or escaping air could suck them against the wall, hurl them through space, shatter their spines against a breast board. Or a shovel might slip and slice a man’s forehead clean open. Or fire could lick through the tunnel. Or the bends—the dreaded bends—could send nitrogen bubbles racing to their knees or shoulders or brains. Walker has seen men collapse in the tunnel, grasping at their joints, their bodies ribboned in sudden agony; it’s a sandhog’s disease, there is nothing anyone can do about it, and the afflicted are taken back to the manlock, where their bodies are decomp
ressed as slowly as possible.

  But these things don’t scare Walker—he is alive, and in yellowy darkness he uses every ounce of his body to shove the river tunnel along.

  The muckers have a special language—hydraulic jack, trench jack, excelsior, shimmy, taper rings, erector shield—but after a while their language is mostly silence. Words are precious in the compressed air. “Goddammit!” brings a bead of sweat to the men’s brows. An economy of hush and striking shovels, Walker breaking it very occasionally with his own gospel song.

  “Lord, I ain’t seen a sunset

  Since I come on down.

  No, I ain’t seen nothing like a sunset

  since I come on down.”

  As he sings, Power and Vannucci time their digging to the rhythm.

  A tube sucks out the water from around their feet. The men call it the toilet, and sometimes they piss right into it so the smell doesn’t hang around. Nothing worse than stale piss in the heat. They hold back their bowels so they don’t have to shit, and, besides, it’s difficult to shit in air that’s twice its normal pressure; it all stays in the gut until later, when they hit the water of the hog-house showers. Sometimes it comes out without warning, and they yell through the mist of hot air, “Who spiked them barbecue beans?”

  Two hours of work and the tunnel is three feet deeper in length than before. The excavated muck has filled many small carriages, the containers shunted back and forth on the railway track with great regularity.

  Vannucci watches Walker and learns from him. The Italian has a long stringy body, with blue veins striated on his arms. For this, the men call him Rhubarb. He first came down as a dynamiter, lighting and blasting and uncoiling his way through the tunnel’s opening, but the blasting was finished early and there was just pure muck left. A man can’t blast muck, much as he might want to, but Rhubarb still keeps a wrapped fuse in his pocket as a talisman. He has few English words with which to talk to the other men, so he speaks in his work and they respect him for it. Rhubarb hefts another shovelful of muck, while beside him Walker grunts.
