The tin can sat on the fence post at the eastern edge of the Cooley place for seven years, rusted to the color of dried blood, its label long since scoured away by wind and grit and the indifferent friction of seasons. A length of baling wire held it in place, twisted tight around the post by a boy who had been eight years old when he did it and was now fifteen and gone. The bottom of the can had been shot through with a .22 rifle — a single hole, perfectly round, the metal petals of the exit wound curling outward like a flower that bloomed only in violence. Below the can, on the ground, a scatter of pebbles and clods of baked earth marked where three children had taken turns aiming at it across five summers. The youngest had never hit it. The middle child had hit it once and never again. The oldest had hit it routinely by the end, and the satisfaction had worn thin by the time the dust storms started coming.

The can made a sound when the wind was right — a hollow, metallic vibration that traveled across the yard and through the single-pane kitchen window, a sound that had once been the rhythm of the house, the background music of afternoons when Jesse Cooley was in the fields and Mabel was at the stove and the children were playing target practice with a rifle that had belonged to Jesse's father. By the spring of 1933, the sound had become something else. The wind that made the can sing was the same wind that carried the topsoil of Cimarron County in a dark cloud that blotted out the sun at two in the afternoon, that sifted through every crack in the clapboard siding, that settled on every surface in the house in a fine brown film that Mabel wiped away in the morning and found again by noon and stopped wiping away entirely by March.

The can stopped making its sound in April. The baling wire had been sawed through by the constant friction of the wind against the rusted metal, and one morning the can was simply gone — lying on its side in the ditch, half-buried in the silt that had drifted against the fence line like snow. No one picked it up. No one replaced it. The bare fence post stood against the sky, a marker of something that had been and was no longer.

Inside the house, the kitchen table told a more complicated story. It was a trestle table that Jesse had built the year they married, twenty-two years earlier, from pine boards that had cost him a day's wages and a day's labor. The surface of the table bore the marks of two decades of meals and arguments and homework and mending: knife scars from where the children had carved their initials, a dark ring from a hot skillet set down without a trivet, a pale oval where Mabel's mixing bowl had sat every morning for twenty-two years. But by May 1933, the table told a different story — one written not in marks but in absence. The mixing bowl no longer sat in its accustomed place because there was nothing to mix. The canning jars that had lined the pantry shelves, filled with tomatoes and green beans and pickled okra from the garden that Mabel had tended behind the chicken coop, were empty now, their glass interiors filmed with the residue of food that had been eaten months ago. They stood in a row on the lowest shelf of the pantry, twelve quart jars and eight pint jars, washed and dried and waiting for a harvest that would not come.

The dust told the rest. It accumulated on the table in a layer that Mabel had measured unconsciously — a finger's width on Monday, a palm's width by Thursday. She stopped wiping it. The dust was the only thing that came regularly to the Cooley house in the spring of 1933, and after a while it seemed wrong to erase the only visitor that still showed up.

The ledger book sat on the shelf above the kitchen table, wedged between a dog-eared copy of the Farmer's Almanac and a tin box that held buttons and safety pins and a single Indian Head penny from 1907. The ledger had been Jesse's father's before it was Jesse's, and the first thirty pages were filled with entries in a hand that was smaller and tighter than Jesse's — columns of figures in pencil, debts and credits, the arithmetic of survival in a place that had never made survival easy. Jesse's entries began on page thirty-one, in a looser hand that used capital letters for emphasis and sometimes forgot to carry the decimal. The entries for 1929 and 1930 and 1931 told a story of small margins and narrower escapes: a good crop of winter wheat in '29 that paid off the note on the harrow, a bad year in '30 that meant trading eggs for flour at the general store in Boise City, a worse year in '31 that ended with a line drawn across the page and the word "CARRY" written in capital letters that pressed so hard into the paper that the pencil had broken.

The entries for 1932 were different. They began in January with the usual optimism — seed orders, a note about repairing the south fence, a calculation of how many bushels would be needed to break even — and then, in March, the entries stopped. There were six blank pages after March 14, 1932. Then, on what would have been page thirty-eight, the paper was torn — not cut, not carefully removed, but torn, the ragged edge still attached to the binding, the page itself gone. The page after that was torn too. And the one after that. Six pages, torn out in sequence, each leaving a rough fringe of paper along the spine. After the torn pages, the ledger was blank for the rest of its length — clean, lined paper that had never been touched by pencil or pen, waiting for numbers that would never be written.

The photograph was the only object in the house that Mabel still touched with care. It was a studio portrait, taken in Guymon in 1928 when the wheat had been good and the future had seemed like a straight road rather than a narrowing path. The photograph showed all five of them — Jesse standing stiffly in his Sunday shirt with the collar that was too tight, Mabel seated in front with the baby on her lap, the two older children flanking them with faces scrubbed pink and hair slicked down with water. The photographer had painted the backdrop to look like a garden, with painted roses and a painted sky, and the Cooleys looked like visitors from another planet planted in front of it — their clothes too worn, their faces too weathered, their eyes holding something that the painted garden could not contain.

In May 1933, Mabel took the photograph from its frame — a cheap wooden frame with a crack in one corner — and wrapped it in her best handkerchief, the one with the embroidered blue flowers that her mother had given her on her wedding day and that she had never used, not once, not even for church. She folded the handkerchief four times, each fold precise and unhurried, and placed the wrapped photograph in the tin box with the buttons and the safety pins and the Indian Head penny. She closed the lid. The box went into the carpetbag that sat by the front door, next to two other carpetbags and a flour sack tied with twine.

The scratch marks on the doorframe told the story of the children in vertical inches. The lowest mark was dated 1921 — the year the youngest was born, though the mark itself was made in 1924, when the child was old enough to stand still against the doorframe while Mabel held a ruler flat on top of her head and Jesse scored the wood with his pocketknife. The second mark was higher, dated 1922 and 1925 and 1928, each date slightly above the last, a ladder of growth that climbed the doorframe in increments that became smaller as the years passed. The third mark was the highest — begun in 1920, reaching nearly to the top of the doorframe by 1931, when the boy who had made it stopped growing and started looking west, toward California, toward the road that led out of Cimarron County and into a future that had no room for scratch marks on doorframes.

The final mark was the date written next to the highest scratch. It was not a growth mark. It was written in pencil, in Mabel's hand, and it said simply: "Left. March 1932." Below it, in smaller letters that had been added later, perhaps at a different time, perhaps on a different day: "San Bernardino."

The empty space where the truck used to be parked was the last witness. It was a rectangle of packed earth beside the barn, approximately eight feet wide and fourteen feet long, its boundaries defined by the absence of weeds — the ground had been shaded and compressed for so many years that nothing grew there, even after the truck was gone. The truck itself had been a 1928 Ford Model AA, bought used in 1930 with money that Jesse had borrowed against the winter wheat. It had been the first truck the Cooleys had ever owned, and for two years it had been the center of the farm — hauling seed, carrying harvest, making the thirty-mile trip to Guymon for supplies that couldn't be found in Boise City. The truck had left tire tracks in the yard that were still visible in May 1933, two parallel grooves in the hardpan that led from the parking space to the county road and then turned west.

The truck had been sold in February 1933. The buyer was a man from Texas who had driven up in a newer truck and paid in cash — thirty-seven dollars, counted out on the kitchen table in bills that were creased and soft and smelled of tobacco. Jesse had signed over the title on the back of an envelope because there was no proper paper in the house, and the man from Texas had driven the truck away with a wave that was too cheerful for the occasion. The empty rectangle of earth had been filling with dust ever since.

The three sealed documents arrived in sequence, each in a different way, each marking a different stage of the dissolution.

The first came in February 1933, delivered by a man in a dust-colored suit who drove a dust-colored car and spoke in a voice that was flat and practiced and utterly without inflection. The document was the foreclosure notice from the First National Bank of Boise City, and it was sealed in an envelope of heavy cream-colored paper that bore the bank's embossed letterhead. The notice stated, in language that was formal and relentless, that the mortgage on the Cooley farm — taken out in 1929, refinanced in 1931, extended twice by the grace of a bank manager who had gone to school with Jesse's father — was now due in full. The amount was $847.62. The Cooley farm was worth perhaps three hundred dollars on the open market, and the open market in Cimarron County in February 1933 was not open at all.

The envelope lay on the kitchen table for three days before Jesse opened it. The dust that settled on the unopened envelope was the same dust that settled on everything else.

The second came in April 1933, in the regular mail delivery that still reached the Cooley place three times a week, carried by a postal carrier named Mr. Henderson who had been delivering mail along Route 2 since before the war and who now drove his route with a wet handkerchief tied over his mouth and nose. The second document was a relief check from the Federal Emergency Relief Administration — one of the first checks issued under the new program, one of the millions that would flow into the Dust Bowl over the next three years, one of the too-little-too-lates that would become the signature of the era. The check was for fourteen dollars. It was addressed to Jesse C. Cooley, Rural Route 2, Boise City, Oklahoma, and it was sealed in an envelope of thin brown paper that tore when Jesse opened it.

The check arrived too late for the truck, which had been sold two months earlier. It arrived too late for the seed, which had not been planted because there was no moisture in the soil and no money to buy seed even if there had been. It arrived too late for the mortgage payment, which was now four months past due and accumulating interest at a rate that the ledger book's torn pages could no longer calculate. Jesse cashed the check at the general store in Boise City and bought flour, salt, bacon, and a sack of dried beans. The flour sack went into the carpetbag by the door.

The third came in May 1933, not in the mail but by hand — a letter passed from a neighbor to a neighbor to a neighbor until it reached the Cooley place, carried by a boy on a bicycle who had ridden six miles through the dust to deliver it. The letter was from the oldest son, the one who had left for California in March 1932, the one whose scratch marks climbed highest on the doorframe. It was postmarked San Bernardino, California, and it was sealed with a blob of red wax that had cracked in transit. Inside, written on a single sheet of lined paper torn from a composition book, the son described his life in California: the fruit-picking jobs that paid fifteen cents an hour, the room he shared with five other men from Oklahoma, the diner on Fourth Street that served coffee for a nickel and let you sit as long as you wanted if you kept buying refills. He described the weather, which was warm and dry but not dusty. He described the mountains, which he could see from the window of his room, purple and white and utterly unlike anything in Cimarron County.

He did not ask how they were. He did not say he missed them. He did not say he was coming back.

The letter included five dollars in cash, folded into a square so small that Mabel almost missed it. She found it when she refolded the letter, and she tucked it into the tin box with the photograph and the buttons and the safety pins and the Indian Head penny. The letter itself joined the other sealed documents on the shelf above the kitchen table, next to the ledger book and the Farmer's Almanac, and the dust settled on it in a layer that Mabel did not wipe away.

The windowsill held the final measurement. By late May, the dust on the sill had accumulated to a depth of two and three-quarter inches — measured by the faded marks on the window frame, where Mabel had once scratched dates to track the children's heights and had more recently scratched lines to track the depth of the dust, as if measuring the one thing that still grew in Cimarron County. The dust was fine and silvery-gray, the consistency of talcum powder, and it held the impressions of everything that had touched it: the track of a beetle that had crawled across the sill and died in the corner, the wing-prints of a moth that had battered itself against the glass, the faint outline of Mabel's fingertip where she had traced a line through the dust on the last morning, testing the depth one final time.

The carpetbags sat by the front door for two days. Then, on a morning in early June when the sky was the color of old brass and the wind had dropped to a whisper, the carpetbags were gone. The front door stood open for an hour — long enough for the dust to drift in and settle on the floor where the carpetbags had been — and then someone, perhaps a neighbor who had come to check, perhaps the postal carrier making his rounds, pushed it closed.

The scratch marks on the doorframe remained. The photograph of the Cooleys, wrapped in Mabel's best handkerchief, remained in the tin box in the carpetbag that now sat in the back of a neighbor's truck, heading east toward Kansas, toward Wichita, toward the cities where women could find work in laundries and men could find work in factories and children could go to schools where the dust did not drift through the cracks in the walls.

The ledger book with the torn pages remained on the shelf above the kitchen table, its blank pages waiting for numbers that would never be written, its evidence of debt and absence preserved under a layer of dust that would grow deeper with each storm until someone — a bank agent, a county assessor, a curious child — opened the door and found the record of what had been.

The tin can in the ditch remained where it had fallen, gradually subsumed into the earth, its rusted metal becoming indistinguishable from the soil it rested in, its hole like a single eye that had seen everything and would remember nothing.

The empty space where the truck had been parked remained empty for seventeen years, until a man who had never heard of the Cooleys bought the land at auction and plowed it under and planted winter wheat that failed in the first year and succeeded in the second and failed again in the third, because that was the rhythm of Cimarron County and nothing, not even the absence of a family, could change it.
