The Remainder

The escapement is not the clock. People say the escapement is the clock and they say it in the Hall, in front of me, to visitors, and I have stopped correcting them because I corrected them for thirty years and it did not take.

The escapement is a gate. It lets the train move one tooth at a time and it takes a small bite of energy to do it. The clock is the pendulum. Everything else in that case exists to keep one weighted rod swinging in a vacuum against nothing, and to count.

I say this because I am about to describe a fault, and a man who does not know where a clock is cannot be told where a fault is.

The fault is mine. That has been the finding for fourteen years and I have never contested it, because the alternative finding is that the pendulum is wrong, and a pendulum in an evacuated case at a controlled temperature is not wrong. It is the least wrong object on the continent. It is very close to being the only thing on this plateau that is not lying to somebody.

The fault: a drift. Small. Not in the rate. In the rate of change of the rate, which is a different animal and which the Council has never once understood no matter how I put it. The clock does not run fast or slow. It runs fast and slow, in a slow breathing, over a period of some months, and the breathing does not correlate with temperature or with barometric pressure or with the seismic record or with the mains supply or with anything at all that I have been able to name in fourteen years of naming things.

I correct it by hand. Weekly. I have corrected it eleven hundred and four times. My father corrected nothing, because in my father's time it did not do this.

The Council's position is thermal. I have measured the thermal. The Council's position remains thermal.

Prel came up at the change of the watch with the tea I have told him twice not to bring into the case room. He is nineteen and he is the twelfth of the line if he lasts, and he will not last, because he has the hands and does not have the temperament. He asked me why I bother with the log when the Republic has instruments that log themselves.

I told him that an instrument that logs itself has no witness, and that a number with no witness is a rumour.

He said that was a very old-fashioned thing to say. He is right. It is also correct. Both of those can be true and it is the great tragedy of the young that they think finding the first one exempts them from the second.

The sky is doing something in the east.

Prel is at the window and has been for some minutes and is describing it to me, badly, in the way of a boy who has never had to describe anything for a record. Gold. Columns. A curtain. He says it is the most beautiful thing he has ever seen and he says it twice.

I am at the case. I am at the case because the pendulum is where I am supposed to be at seven minutes past, and because whatever is happening in the east has been happening for some time in one form or another and will be reported on by better-placed men than me, and because a keeper who leaves the case to look at the weather is not a keeper.

That goes in the book in my own hand, because in the days since I have been asked four separate times whether I saw it, and the answer is no, and every one of the four found that answer harder to believe than anything else I told them.

The drift stops.

I want to write that again with the reading beside it and I find that I cannot, because there is no reading beside it. There is no departure to record. The pendulum is at the arc it should be at, at the moment it should be there, and the correction I had queued for the eleventh is not required, and the correction after that will not be required, and I know that in the first four seconds the way you know a door has stopped rattling in a house you have lived in your whole life.

Prel is still talking about the sky.

I take the reading four more times because four is what the procedure says and because my hands want something to do.

Perfect. It is perfect. It is the number my great-grandfather's notes give for a theoretical case with no fault in it at all, a number I have understood since I was fourteen years old to be a thing you approach and do not touch, the way you approach the horizon.

I have been fighting this instrument for forty years. I have been humiliated by it in front of the Council on nine occasions. I have a drawer of correspondence with the Physical Bureau in which men younger than my son explain thermal expansion to me.

And the fault was never mine.

I sat down on the floor of the case room. That goes in as well, undignified as it is, because a record with the undignified parts taken out is not a record, it is an advertisement. I sat down with my back against the case and the most accurate instrument in the world ticking above my head at last, exactly, forever, and I did not feel what I had expected to feel for forty years.

I felt as a man feels who has come home to a quiet house and understood, from the quality of the quiet, that someone has left.

Chancellor Thane came down at some point. I did not note the time, which is the first entry in eleven hundred pages of this log without a time on it, and I am leaving it as it stands.

She came alone, which surprised me, and she did not look at the clock, which did not.

She wanted one thing. She wanted to know whether the plateau's temporal instruments had settled, all of them, in agreement, at a common moment, and whether I would put my name to that. I said they had and I would. She asked me the moment. I gave it to her to the tenth.

She wrote it in a book of her own and she thanked me and she asked, on her way out, whether the settling meant the instruments were now reliable.

I said that it meant they had always been reliable and that something had been interfering with them.

She stopped at the door for perhaps a second and a half, which is a very long time for that woman, and then she said that the distinction was not operationally relevant tonight, and she went up to the Hall, where I could hear them already, envoys arriving at the hour, boots on the stair all night, the Republic assembling something enormous out of the fact that I had just given her.

She is not a cold woman. I want that on the page too, because she will be written about badly. She is a woman who has been handed a catastrophe and has seventy-two hours, and a man on the floor of a case room grieving a fault is not a thing she has time to be curious about.

Nobody has time to be curious. That is what the world is now. I have thought about it a great deal since and I have decided it is not a complaint.

I resume the log properly. I apologise to any successor for the gap.

I have taken the reading daily, at four fixed points, using the mercury contact and the optical, independently, and averaged, and corrected for temperature by the Bureau's own tables which I do not trust and have used anyway so that nobody can say I did not.

There is a remainder.

It is very small. It is smaller by a factor I will not embarrass myself by writing down than the fault I fought for forty years. It is not the same shape. The old fault breathed. This does not breathe. It is level, and it is one-directional, and it is present at every one of the four daily readings and has been for eleven days.

It is not thermal. I have measured the thermal.

It is not the mains. I disconnected the case room from the mains for a full day, at my own cost in tallow, and it persisted.

It is not the mountain. The seismic record is the flattest it has been in fourteen years.

It is under the floor. I do not have any evidence for that sentence and I have written it anyway, which is the only unprofessional thing in this log, and I am not going to strike it, because I have had my hands on this instrument for forty years and there is a way a fault feels when it is coming up through the plinth and this feels like that.

I submitted the finding to the Physical Bureau on the correct form with eleven days of averaged readings appended.

The age of the observer's eyes.

I have taught four men to read that scale. I taught the man who signed that letter.

Prel does not know I am still measuring. I have him on the weekly and I take the other three myself, before the fifth bell and after the eleventh and once in the small hours, and I keep them in a separate book which is this one, and I will keep keeping it, because a number with no witness is a rumour.

The remainder is not going away.

I will not say it is growing. Eleven weeks is not enough to say a thing is growing and I have spent my life refusing to let other men say it on less. I will say that it has not once, on any of the ninety-one readings I have taken, been smaller than it was the day before.

Something under this plateau is off true, very slightly, in one direction, all the time.

And here is the part I would not put in a letter to the Bureau and am putting here because this book is mine and because I am seventy-one and there will be a twelfth of the line or there will not.

I am glad.

I sat on that floor three months ago in a room with a perfect clock in it and I have never in my life been so frightened, and I did not know why until the fourth night, and it is this: a keeper of a perfect instrument is a caretaker. He winds, and he dusts, and he waits to die. It is the fault that makes him a keeper. It is the thing that will not sit still that gives a man forty years of work and a reason to come up the stair at seven minutes past.

I have a fault again. It is under the floor. It is patient and it is level and it is one-directional and nobody in the Republic will hear a word about it from anyone but me.

I do not know what it is. I know its rate to four places and I will know it to five by the spring.

I am the only man on the continent measuring it, and I am glad of that too, and I am aware of what that says about me, and I am going to go and take the reading.
