“Give me the book,” said Hesper.
She said it as soon as he had swallowed the last of the bread.
She sent the rest of them away in four sentences, with the brisk malice of a woman clearing a pub at closing time.
Pask was to unpack the theodolite and check it for dew.
Tam was to water the pony.
Pugh was to find out what was in the river that could be fried.
They went, with backward glances, and she waited until they were out of earshot and then put out one square brown hand, palm up, and wiggled the fingers.
He took the field book out of his coat and gave it to her.
She did not open it at once.
She sat down on the tailboard of the cart with the book in her lap and a pencil in her fist, and turned it over.
It was an ordinary book.
It had a cover of black oilcloth gone gray at the corners, and a brass clasp, and a pencil loop that Wystan had bent back into shape so often that it had stopped trusting him.
She opened it from the back, where the oldest pages were.
Then, to his surprise, she began to read it as one reads a letter from a person one has not seen for years, slowly, with her lips moving a little on the figures.
He stood there, with his hands hanging.
It was a very good field book.
He knew that without vanity, as a man knows his own height.
Every page was ruled in his own hand into columns: station, back sight, fore sight, distance in chains and links, remarks.
There were six months of it.
He had begun it in the first week of Rimemonth, and kept it every day, in the cramped square script that Hesper called a bricklayer’s, and the sheets ran on in orderly files, loop after loop of the Ashmere control, around the village and out along the north bank and back.
“Who set the stone?” she said, without looking up.
“I did.”
“With whom?”
“With you.
In Highsun last year.
You said I could cut the cap.” He could say it steadily if he looked at a point just above her head.
“You said it was the first mark I would make on the world that was likely to outlast me.”
Hesper turned a page.
“I do not recall that, kid,” she said.
She said it flatly, without apology, and went on reading.
He had expected anger, or comfort.
He had not expected the plain statement of a fact, and for a moment he did not know where to put it.
“I am sorry,” he said.
“Do not be.
I am not saying you are wrong.
I am saying I do not recall it.” She licked a finger and turned another leaf.
“What is odd, Wystan, is that I do recall something.
I recall a conversation like that.
I recall it all around the edges.” She made a vague circle in the air with the pencil.
“I recall the weather, and your face, and that I was in a good mood.
And I recall that the middle of it is not there.
It is on the tip of the tongue.” She let the pencil fall.
“I have been trying to get at it since the sixth bell.
I did not know what it was I was trying to get at.
Now I think I do.”
The wind blew a stray strand of hair across her face.
She did not move it.
“Go on,” said Wystan, hoarsely.
“There is nothing to go on with.
I have a gap with a very smooth edge.” She shook her head sharply, as a dog shakes off water, and bent over the book.
“Be quiet now, kid.
Let me do the sums.”
He was quiet.
It was the longest twenty minutes he could remember.
She read the legs of the traverse one by one, and as she read she ran them.
He could see her doing it.
Hesper did not use a slate or a table of logarithms, or even the sliding rule that Pask kept in his case like a holy relic.
She did it in her head, in the old way, with her eyes half closed and her lips shaping the numbers, adding and carrying and turning each bearing into its little east and north, and every now and then she jabbed the pencil at the page and murmured, “Twenty-two chains, fifty links,” or “Back sight on the alder, that is right,” or “Hm.”
A traverse is a simple thing, in principle.
You begin at a known point.
You measure a distance to a second point, and an angle, and then a distance to a third, and so on around a loop, each leg tied to the last, and at the end, if you have been honest and careful, you arrive back where you started.
The figures are added up.
If the loop has closed, the sum of all the little easts and norths comes to nothing.
The beginning meets the end.
If it has not, if the last leg leaves you a few feet short or a few feet over, then that gap is the error of closure, and it is a measure of every small mistake you made along the way, the stretch of the chain, the wobble in the sight, the sneeze at the wrong moment.
A good loop closes to a hand’s breadth.
A very good loop closes to a finger’s.
A surveyor who brings home a perfect loop is generally suspected of cheating.
Wystan’s closed to a finger’s breadth almost every time, which was two centimeters.
It was the one thing about himself of which he was entirely sure.
“Hob loop,” said Hesper, under her breath.
“Closed at two centimeters.
North bank loop, two and a half.
Weir loop, the long one, one and eight tenths, with the crooked bit at Fenn’s Cut, that is lovely, kid, that is better than I do.” She flipped a page.
“Hm.
Hm.
And again to the stone.
And again.
And again.”
She stopped.
She had reached the front of the book.
She had read every loop in it, one after another, forty-one of them, from Rimemonth to the day before yesterday.
She went back and put her finger on the first line of the first loop, and moved it down the columns, and the pencil began to tap.
“Every one of these begins at the Ferry Stone,” she said.
“Yes.”
“And ends at it.”
“Yes.
That is what a loop is.”
“I know what a loop is, you impudent child.” She said it mildly, without looking up.
“I am saying that every single one of them, forty-one loops, from the north bank to the Weir, is tied to one point.
A stone that has a brass cap with a name on it.
And not a single one of them is tied to anything else.”
“They are tied to the Third Bend as well.
The back sight.
See, on the first leg.”
“Yes.
The Third Bend.
And the alder.
And the Hob chapel, as a check.” She was talking faster now, tapping.
“Wystan.
Look.
Suppose I did not know the stone was there.
Suppose someone told me, there is no stone, there never was, and I took your book and tried to work out what you were measuring.
I would take your first leg.
I would run it back from the Third Bend, forty-one chains and eighty links, on the bearing here.
And I would arrive at a point.” She stabbed the page.
“Then I would take your second loop, from the alder.
And your third, from the chapel.
Each of them is a different road.
They begin on different ground.
But they all come out in the same place, to within the width of my thumbnail, and that place is not a place where anything stands.
It is a place where forty-one separate sets of numbers meet, and there is nothing there but grass.”
She looked up at him then.
He had never seen her face so intent.
It was like looking at a hawk.
“Do you see what that is?”
“It is a hub,” said Wystan slowly.
“It is a hub with all the spokes still pointing at it.”
“Aye.
And the hub is gone.” She shut the book on her finger.
“It closes.
That is the devil of it.
It closes beautifully.
It is the best control network I have seen on this river in thirty years, and it closes on nothing.”
A line of ants was crossing the grass at his feet, each one carrying a pale crumb of something.
He watched them go.
“A traverse that closes on nothing,” said Hesper.
“It is the first thing they teach you to fear.
Every novice thinks it is the traverse that does not close that will kill him.
It is not.
A bad traverse tells you it is bad.
It is the one that closes perfectly, on a point that is not there, that tells you somebody has been at the world with a scraping knife.”
“Somebody,” said Wystan.
“Somebody who is very good, and very thorough.
And very, very late.”
“Late?”
“Think, kid.
If you want to take a thing out of a map, you must take it out of everything the map touches.
The sheet.
The Registry.
The tax roll, the parish books, the memory of every man who ever walked it.” She tapped the book.
“And they did.
Look at that grass.
Look at Tam.
They have done a lovely job.
But they forgot this.” She held up the oilcloth cover.
“They forgot that a boy with a chain and a bad habit of exactness had been going round and round it for six months, writing down everything that pointed at it.
They could take the village out of the world.
They could not take it out of your arithmetic.”
A slow heat came up into his face.
It was not quite pride.
It was nearer to being handed back a thing he had not known was missing.
“So I am not mad,” he said.
“I did not say that.” She almost smiled.
“I said your arithmetic is sound.
That is a different thing.
Edwin!”
Pask came running, with his spectacles flashing and a lens cloth in one hand.
“Mistress Quarrel?”
“The control register.
Sheet Fourteen.
Bring it.”
He brought it.
It was a thick, flat book in a green cloth binding, with a ribbon marker and a red Registry stamp on the cover, and it was the one that lay in the bottom of his case under a layer of waxed paper and was consulted only when something had gone wrong.
Hesper took it and opened it in her lap, on top of the field book.
She ran her finger down the first column.
It was a list of benchmarks.
Each of them had a number, in the neat official script of the Cadaster, and under the number a name, and a description, and a set of coordinates.
Fourteen slash one, the church at Fenwick Weir.
Fourteen slash two.
Fourteen slash three, the Third Bend, a cut cross on a rock.
Fourteen slash four, a bolt in the old toll bridge.
Fourteen slash six.
Fourteen slash seven, Hob’s Ford.
She read it slowly, one finger moving, and then read it again.
“Edwin,” she said.
“How many benchmarks are there on this sheet?”
“Six, Mistress Quarrel.
As recorded.”
“Six.”
“Yes.
One through seven.
With the exception of…” He stopped.
His mouth stayed open.
“Oh.”
“With the exception of?” said Hesper, mildly.
“Of five.” Pask had begun to sound faintly ill.
“It is not there.
It goes four, six.
I have always rather supposed that it was a clerical…” He tried again.
“It is a very small error.
The Registry sometimes…”
“Five is the Stone,” said Wystan.
They both looked at him.
“It was entered last Highsun, between the toll bridge and Hob’s Ford.
The register is numbered upriver.
Everything above it moved up by one, and a clerk signed it, and the clerk’s superior signed the clerk.
I copied out the new numbers for Mr.
Pask.
I thought it was the most boring week of my life.”
Pask opened his mouth and shut it again.
“Aye, it would be,” said Hesper.
She did not say that she remembered.
“The Registry does not skip numbers, Edwin.
I have been surveying this Province since before your mother was weaned, and I have never once seen it skip a number.
When it puts a benchmark in, it renumbers.
When it takes one out, it renumbers.
It goes down the whole register and moves every other benchmark up or down, with a little note in the margin, and a clerk signs it, and the clerk’s superior signs the clerk’s signature, and there is an Auditor’s stamp.
It is a hideous, tedious, glorious process, and it takes a month.” She put her finger under the gap, between the fourth entry and the sixth, where a clean sliver of white paper lay between two lines.
“Somebody took this out in a night.
They took out the stone, and the entry, and the village.
They smoothed over every place they could think of, and they were very careful.
But they did not have time to renumber a register.”
“Then,” said Pask, with a sort of dry wheeze, “it is a gap.
A lacuna.
In the official record.”
“Aye.”
“I did not know that was possible.”
“Nor did I,” said Hesper.
She shut the register.
For a time nobody spoke.
Wystan sat looking at the closed green cover, and at the red stamp on it, and the thought rose in him slowly that every number in that book was a promise that somebody had kept.
Every figure in it was a man standing in the rain with a staff and a chain, and a clerk copying down what he said.
It was how the world held its shape.
And somebody had gone into the middle of it and taken out one number, quietly, in the night, and left the two on either side of it standing there like teeth on either side of a gap.
“A hole you can measure,” said Hesper, “is a hole that was filled.”
She said it so softly that he was not sure whether it was meant for him.
She had taken the fennel out of her mouth.
She was looking at the field, at the long green slope, the dew drying on it in the sun, the Hob chapel standing white on the far bank, and her face had the strangest expression he had ever seen on it.
It was not fear, or anger.
It was something older and more tired than either.
It was the look of a woman who has come a very long way to a very ordinary door, and who has found, on the step, a letter in her own hand.
“I have seen a thing like this,” she said, “once.”
“When?” said Wystan.
She did not answer.
She did not seem to have heard.
She turned the pale green stalk in her fingers, round and round, and it snapped in half between her thumb and forefinger with a small dry sound like a breaking bone.
