The chair had a deal back and a seat of eight splinters and a carving under the seat rail, a bird with a worm in its beak, worn smooth in one place by thirty years of a thumb. It stood on Cobb Renn’s board at forty-four pounds, and her mother’s chest stood beside it at twenty-one, and the two came to sixty-five pounds, and the Scale House was paying three shillings the pound for ash delivered against a shortfall on Thursday. Sixty-five pounds at three shillings is nine pounds fifteen shillings. Nine pounds three shillings is what she owed. Six pounds eleven shillings is what was in the purse. So she was two pounds and twelve out, which was seven pence worse than the two winters she had already put in, and that is how she knew, at ten past nine on a Wednesday night in December, with the pen in her hand, that she was going to burn her mother’s furniture.

She wrote the figures down anyway, because a godmother in Emberwyke is an accountant, and an accountant who does not write the figures down is a person with opinions. Nine pounds three shillings, wanted, Thursday, two houses. Six pounds eleven shillings, held. Eighteen pounds, standing to the credit of her own hearth, and no use whatever to her or to anybody, and she wrote that in too, with a line under it, and the line under it said RULE THREE.

A hearth’s own ash may only pay that hearth’s own debts. Given to another household’s fire it is not a gift, it is a claim, and a claim is read aloud at the Scale House within the week with the giver named. Move eighteen pounds off her own hearth and it is a claim with Cobb Renn on it, said out loud in a hall eleven thousand people go through in the evening, and her own hearth goes short and is marked, and a marked name cannot hold a lease, and the house on the Coalquay is leasehold. Eighteen pounds was worth nothing. It was the most expensive nothing in the city.

A guarantee is a debt that somebody else has agreed to pay for you, in writing, and be repaid first out of everything: before the parish, before the Crown, before a coal merchant. About a fifth of the people in Emberwyke are in some way sponsored, and about a fifth are in some way ashamed of it, and Cobb Renn’s trade was to stand in the gap between those two numbers and pretend there was nothing in it. She had eleven hearths on her book. Nine of them were straight. Nine of them paid at the scale and never asked and never quarreled, and Cobb saw to them herself twice a year with a slate and a stub pencil and a good ear for a household that is about to stop being able to pay. Two of them were Thursday.

She had set the Thursday herself, and that was the part nobody knew. Since the September she had looked at the two spring settlements and understood that she could carry them on one week or on two, and that she could not carry them on two, because six pounds eleven shillings is the balance of a deposit on a house, and a deposit is not a thing you are half a week short of on the day. So it was one Thursday, and both, and she had chosen it in September with a pencil, and here it was.

The reason for telling them on the Thursday morning was not kindness. It was this. The Scale House reads a claim aloud with the giver named, at the counter, in one voice at a time, and everything said at that counter is in the Salt Hall by Friday, not as a rule but as what people remember. If Cobb paid both shortfalls on Thursday evening without a word, then on Friday the city would know that two houses had been kept warm and would not know by whom, and Cobb would have done it for nothing, and there is a version of that which is a good trade and takes eleven years to build and about four minutes to lose. If she did not pay, both houses were marked. A mark is seven years without testimony, without a lease, without being counted in a queue, which in Emberwyke is seven years of not being a person who counts.

If she told them in the morning, they would know before the beam did. And telling was cheaper, because a household that has been told can be angry in advance, and a household that finds out at a counter in the rain at six in the evening can only be afraid. That was the whole of the professional judgement, it was correct, and she had made it on Tuesday, and she had been carrying it about ever since.

Hearth 7,102 is on the Coalquay, four doors up from the water stairs, a brick front with a shop that has not been a shop for six years, and the numbers on that street run in threes because the Coalquay was renumbered in 1911 and nobody has had the heart to do it again. She was at the door at eight in the morning with the chair under her arm. Ottoline Vray was on the step. That was the first thing and it was the whole of the morning, because Cobb had a chair under her arm and a girl of nine on the step, and the two of them looked at each other, and Cobb understood inside a second and a half that she was about to do the stupidest available thing with a piece of furniture. “Who is it for?” said Ottoline. “It is for you,” said Cobb.

“It is for the house,” said Ottoline. “That is what you said last time. It is for the house, and you put it in the house, and then the house owes it.” “I did not say that.” “You said the house would have it,” said Ottoline, “and the house is not a person, so it does not say thank you, and then it is on the board against the number, and the number is 7,102, and 7,102 is here.” She turned the hat up again, which Cobb had learned was not a thing the girl did when she was pleased. “If it is for me then it is a claim on me, and I have nothing to answer with, so it is better if it is for the house.” Cobb Renn stood on a step in the cold with her mother’s chair under her arm and a nine-year-old explaining the law of her own trade to her. “Sit down,” she said. So Ottoline sat down on the step in the grey felt hat, and Cobb set the chair in the doorway where it would not be seen from the street, and went in.

Inside, the fire was low and there were two people, and Cobb counted the room before she said good morning, which she did in every room. The room came to five, and one of the five was not counted before. Hearth 7,102 was short twenty-two pounds. She said it in the first minute, because there was no way of saying it in the fourth minute that was better. She said the number and the day and what a short was, and what a mark was, and what seven years without a lease or a hearing was, standing, with her purse in her hand, and she did not say I am sorry, because a godmother does not apologise for a figure, and she did not say I will see it through, because she would not be there on Thursday evening to say it. Then she said the other thing, which had been sitting in her since Tuesday.

“I have been charging you two shillings the pound,” she said. “Since the spring before last. The Scale House charges three. I have been putting the other shilling in myself and telling you the fuel was dear. It was not the fuel. It was me. I would rather you had that from me than from the man at the counter.” Nobody spoke for a while. The fire was low because the coal was low, which was the other half of what she had been doing on their account and was not mentioned. “Then we owe you money,” said the woman. “You owe me money,” said Cobb. “Twenty-two pounds at three shillings the pound is sixty-six shillings, which is three pounds six. I will take that out of it that the house has to live. That is not a favour. It is the trade, and if I let a house be short I am not a godmother, I am a woman who has said a number out loud in a doorway.”

“Three pound six,” said the man. “And at four o’clock on Friday I will bring the rest, and the mark will not be made, and there will be no entry against 7,102 in the Cinder Ledger at all, and nobody will ever be able to prove that this morning happened, and I would prefer that.” “Except the girl,” said Ottoline Vray, from the step, where she had not gone in. Hearth 4,318 is at the corner where the Coalquay turns into the Rope Walk, and it is the last house on that stretch with a yard, and the number is in the third course of the chimney with a maker’s tick under it, because the Rope Walk chimneys were all cast off the same board in 1888 by a man who signed his work with a little hammer cross and was proud of it. Mared Holt opened the door before Cobb knocked, which she always did, and had the barrow in the passage behind her with the tarpaulin folded, because it was half past nine and she had been out.

She is sixty-one, and has twenty-nine years of it with a barrow and a tarpaulin, and holds the longest clean board on the Rope Walk, which in a street where the only thing anybody has is the figures on a slate means she has a run of figures nobody can fault. She apologises before every sentence, including the word no. “I am sorry,” she said. “I am sorry, you are early. I am sorry, come in, I am sorry, it is cold.” The room was one room and a board, and the board was on the wall by the fire, ruled in nights, and the right-hand column was full to the fourth of January in the same upright careful hand, and Cobb looked at it for longer than she meant to. “You are the cleanest board on the Rope Walk.” “I am sorry,” said Mared Holt. “I am sorry, it is a way of keeping the figures.”

Hearth 4,318 was short thirty-nine pounds. Cobb said the number, and the day, and the mark, and the seven years, standing, in the same flat voice, and Mared Holt listened to the whole of it without moving and then said: “I am sorry. I am sorry, I am not going to say no, and I am sorry that I am not going to say no, and I am sorry that I am going to say no.” She put her hand flat on the board.

“Nine weeks,” she said. “Nine weeks I have not missed a night, and I have never once been late in twenty-nine years, and I know what this board says the way I know my own hands. I am sorry, but that is not thirty-nine pounds. That board has not got thirty-nine pounds in it. I have not had a short since ninety-one, and I know what the difference is, because the difference is the smell of a hearth when it goes over, and it has not gone over.” “It has not gone over,” said Cobb. “I have not come to tell you it has. I have come because I know that on Thursday the beam is going to say that it has, and I set the date myself in September with a pencil, and I would have told you in June if I had been able to stand it in June.” “You knew in June.” “I knew in September and I did not tell you until December, and both of those are bad, and I am not going to argue with you about which is worse, because I am a woman who writes things in September and waits.”

“If you can pay it yourself,” she said, “you pay it yourself, and I stand at the counter and say the words. Thirty-nine pounds at the Scale House is five pounds seventeen and sixpence, and you have not got that, and I have not got that, and if either of us had it I would not be standing in your doorway.” “And if neither of us has it?” “Then I pay it,” said Cobb. “That is the whole of what a guarantee is. I pay it first, out of everything, before the parish and before the Crown, and I am repaid in the spring, and that is the trade, and I have been doing it eleven years and I am not tired of it.” Mared Holt put her hand on the board again and said the thing she had been not saying since Cobb came in.

“In ninety-four a woman taught me the figures,” she said. “I am sorry. She taught me the figures and the discipline and she took the winter’s money, and I was thirty-two and I had nobody to say it to, and I have never once said it out loud, and I am not saying it out loud now. I am telling you about a woman.” “You are saying it out loud now.” “I am sorry,” said Mared Holt.

She would not take ash. That was the last thing and it was the thing that cost Cobb the morning. “If you put another hearth’s ash on my board,” she said, “then my board says a thing that did not happen, and my board is a legal instrument, and a figure on a board that was not weighed is a forgery, and the forger loses their hearing and their name for a year. So I will not have it, and I am sorry.” “I was not going to give you another hearth’s ash.” “Then what were you going to do with the chair?” “Nothing has happened to the chair.” “I am sorry,” said Mared Holt, “but you are holding your own board in your head, and I have read boards for twenty-nine years, and you have been in this room four minutes.”

Cobb Renn sat down on the edge of the table in a one-room house on the Rope Walk and told the truth, which took ninety seconds, and it came out as a list of weights, because that is the only shape she has for anything. Her mother’s chair, forty-four pounds. Her mother’s chest, twenty-one pounds. Both entered in the goods column, valued once in 1908 and never again, because the goods column is the one column in the Cinder Ledger that is valued by eye and never goes anywhere near the beam. Burning a thing of a person’s is a claim against them, entered the same night at the value the board gives it, and a person whose things are burned may answer for the debt in kind.

“If I burn the chair and the chest in my own hearth,” she said, “it comes in at sixty-five. Sixty-five at three shillings is nine pound fifteen. I owe nine pound three. And the owner of a burned thing is named on the entry, and the owner is my mother, and my mother has been dead since 1919, and a dead woman cannot be called on to answer in kind, and the claim runs into an empty room and stops there.” “Your mother,” said Mared Holt. “My mother. Whose chair it was. Who sat in it every evening of my childhood and would not let anybody put a foot on the rail. I have not sat in it since I was nineteen. I have carried it from house to house for eleven years, and it has stood at forty-four pounds in the goods column since 1908, and forty-four pounds is a great deal for a chair.”

“That is not a payment of the hearth. That is the sale of a thing.” “It is the only sale of a thing this city will take off me on a Thursday afternoon, and I would rather burn it than put a false figure on a board, and I would rather burn it than have two houses marked for a sum I cannot pay, and I have thought about the third thing, which is my own eighteen pounds, and rule three is why I would rather burn a dead woman’s chair.”

At ten o’clock, in the doorway of 4,318, a woman of the Coalquay asked her. “We have been talking,” the woman said, “about the spring settlement.” “Your settlement is the second Thursday,” said Cobb, without looking at her, because she knew what was coming the way you know a step is missing in the dark. “Yes. And my mother-in-law is asking whether you would look at us. Not this week. I know about this week. I am not asking for this week.” Cobb did the arithmetic. She could not help doing the arithmetic. It was not a talent, it was a place her mind went. Seven thousand one hundred and two, twenty-two pounds, sixty-six shillings. Four thousand three hundred and eighteen, thirty-nine pounds, a hundred and seventeen and six. Total, nine pounds three. In the purse, six pounds eleven. The chair and the chest, nine pounds fifteen. Over by twelve shillings.

And the woman in the doorway had said, without saying it, that her hearth would be short four pounds on Thursday, and four pounds at the Scale House is twelve shillings. Cobb counted the doorway: one woman, one step, one child behind the curtain of which she could see the edge, and herself, and the girl on the Rope Walk behind her, still apologising to nobody. She took the purse out and the green wax out and put the wax on her thumb and held it and signed on the back of a slate, in a room with the door open. “I will see it through,” she said.

Burning a chest takes an hour and forty minutes alone in a good draught, and Cobb Renn was not alone, because the rule is that nothing in Emberwyke is done alone in a house with a hearth in it. Halden Holt came, and Sefa his sister, and Ottoline Vray, who was at the door before either of them and would not be sent away, and the four of them took the chair apart with a saw and a hatchet at the joints where the joiner had been careless, which is where a chair comes apart if you know it. She did not tell them what it was for. She said it was going to the Slag Bank, and the Slag Bank takes anything, and the column for the Slag Bank is called disposed, and the disposed column is never checked, because the disposed column is a hole in the ground with a heading over it and nobody in this city has ever been curious about the ground.

At five o’clock she was at the Scale House with two barrow-loads of a grey that was not quite ash, and a slate, and the green wax, and Mared Holt, who had come although nobody asked her, and Ottoline Vray on the step with her hands behind her, because she had been told to and would do what she was told when it was a rule. The Scale House is the only stone building in the city: a plank floor stained in three generations of ash, a counter of oak, and at the far end the beam, a bronze yoke on a cast-iron column, twenty feet of throw, with a stow of duck-weights down one side and a catch-pan under it. Two clerks, a beam-man, and a queue, and the whole city comes through in the four hours after dusk, and the sound of it is one voice at a time saying a number.

The line went out of the door and along the front and past the corner and stood in the street, and the rain came in off the plain sideways, and the Scale House bricks were the only dry stone in Emberwyke and every person in the queue leaned on them. Cobb had been in that line for eleven years and she knew where in it a godmother is allowed to stand, which is not at the front, because a godmother at the front is a person who has come to be served, and at the back, which is where a person stands who has come to pay for somebody else and does not want the queue to know whose. The beam took the gray and came down on six pounds and three ounces. “Claim value, sixty-five pounds,” said the beam-man. “At the value of the board.” “Yes,” said Cobb.

The beam and the claim are both correct and nobody in Emberwyke has ever reconciled them, because the goods column is the only column that is valued by eye. Then the line came round to the two of them. Seven thousand one hundred and two: short twenty-two pounds. Cobb Renn, guarantor, set twenty-two pounds of claim value against it, and the clerk wrote NOTHING in the mark column and initialled it and turned the page, and there is no entry against 7,102 in the Cinder Ledger at all, and nobody in that hall will ever be able to prove that this story happened, and Cobb would prefer that. Four thousand three hundred and eighteen: short thirty-nine pounds. Cobb Renn, guarantor, set thirty-nine against it. Twenty-two and thirty-nine is sixty-one. Sixty-five less sixty-one is four pounds, and four pounds stood to her own hearth at the end of the evening, which was a thing she had had on Wednesday night and had not had on Thursday morning. At ten past seven the third hearth came to the counter, which is 6,214 on the Coalquay, and it was short four pounds, and Cobb Renn set the four pounds against it, and the clerk wrote NOTHING in the mark column again, and the margin was gone.

A claim is entered in the ledger the same night, and the ledger is read aloud in the Salt Hall by anybody who cares to attend, and Cobb Renn stood at the back of that hall at nine o’clock waiting to hear her own name read out for burning her mother’s chair. The entry was short and entirely without malice. CLAIM ENTERED. Ninth day. Value of goods burned, sixty-five pounds, at the value of the board. Owner: NELL RENN, late of this city, deceased. Giver: the person burning. And then, because the clerk was new, he read the whole of it, including the last four words, in a hall with no fire in it and six tall windows running with water, in front of about two hundred people. “Owner: Nell Renn, late of this city, deceased. Giver: Cobb Renn.” Nobody said anything. A woman near the door said “poor love” to the person beside her, in the tone of somebody settling a dispute about a basket of eggs.

On Friday morning at eleven she went down the Coalquay with the purse, and a man named Pyle who had two houses and would rather have one of them took her to the outside of number two thousand one hundred and six and pointed up at the third course of the chimney, where the number was in the brick and the maker’s tick was under it. “The lease is a hundred and forty years,” he said. “I am sorry, Cobb. I am sorry, I know what it is for. I have known since October.” “The balance was nine pounds four.” “It was.” “There are six pounds eleven in this purse, and the other two pound five is two winters of a shilling the pound, taken out of two houses on the Coalquay in the ordinary way, and it has been in here since the September, and I put it here myself, with a pencil.” Pyle looked at the number in the brick for a while.

“The next one on is in the spring,” he said. “Yes,” said Cobb Renn. “It will be.” She stood in the road and counted the rooms through the unglazed window, because she counts every room she goes into, and this one she had counted eleven times since September: a kitchen, a room, a room, a scullery with its door off the hinge, a yard, the number two thousand one hundred and six in the brick above her head, nobody in it, and nothing in it that was hers. Then she went on down towards the Coalquay, because her feet knew the way, and it was a quarter past eleven, and the Scale House opened at twelve.
