When she had finished, Halden leaned back in his chair, and he laughed — not unkindly, but with the easy confidence of a man who has just been offered a bargain he is certain to win — and he said, "Miss Ivers, you are a brave woman, and I admire bravery, even when it is misplaced. You are asking me to sign a paper that says my way of watering, the way my father watered and his father before him, will be judged against a schoolteacher's arithmetic, on a field that has never grown anything on time in its life. Very well. I will sign it. I will sign it because I am certain of the outcome, and because a certain man can afford to be generous."
He took up his pen, and he signed his name at the bottom of the paper, in a large, flowing hand, and then he looked up at her, and his expression hardened, just slightly, into something more serious than confidence.
"But understand me, Miss Ivers," he said. "If your trial fails — and it will fail, because water does not run in measured turns, whatever your notebooks say — then the matter is closed. You will not bring figures to this association again. You will teach your children, and you will leave the water to the men who work it. That is the price of your wager, and I want it written in the paper before I sign, so that there is no argument afterward about what was agreed."
Selma nodded, and she took the pen, and she wrote the condition into the paper herself, in her plain hand, beneath his signature: *If the trial fails, I will bring no more figures to the association, and the schedule will stand.* She wrote it steadily, without flinching, because she had known, coming in, that this would be the price, and because she had decided, on the walk home from the refused proposal, that a price was not a reason to refuse a trial. A price was only the measure of how much the trial mattered.
Eben signed next, as the landowner lending the field, in his slow, careful hand, and Ketchum signed as witness and measurer, and Selma signed last, her own name beneath theirs, and the four signatures stood on the page together, in different hands, like four different kinds of writing telling the same story: a schoolteacher, an orchardist, a surveyor, and a commissioner who was certain he had just won.
Rolf Halden, who had watched the signing without speaking, walked with Selma to the door, and on the step, in a low voice, he said, "Miss Ivers, when the measuring begins, may I watch? Not to interfere. Only to see how it is done."
She looked at him, and she thought about his question in the schoolhouse, about depth and amount and timing, and she said, "You may watch, Mr. Halden. Measurement is not a secret. Anyone who wishes to see it done is welcome to see it."
He nodded, and he did not smile, but something in his face eased, the way a person's face eases when they have been given permission for something they were afraid to ask for, and he went back inside, and Selma walked home through the spring evening with the signed paper folded in her pocket, and the receipt from the surveyor beside it, and the feeling, rising in her like water rising at a gauge post, that the season ahead would be the most honest season of her life — because, for the first time, the valley would not be asked to believe her numbers. It would be asked to watch them work.
The morning after the signing, Ketchum came out to the orchard with his instruments in a leather case, and Selma and Eben walked the ground with him while he set the trial in order, the way a surveyor sets any work in order: by fixing the points first, so that everything measured afterward would be measured from the same places. He drove a gauge board at the headgate of the trial plot, and another at the headgate of the upper rows, each board painted white with black inch marks, each set in the same kind of ground, at the same depth, so that no one could say afterward that one board had favored its field. He showed Selma and Eben how he would read them: at the same hour each week, with the gate set the same way, the depth noted, the width noted, the speed of the water taken by timing
