His first design was too ambitious. He pictured the stones holding shade all day, storing moisture, protecting roots from hot wind, and directing every drop of rain exactly where he wanted it. Without understanding how much open soil and airflow the plants still needed, he built a tight arrangement several layers high around their bases. The stonework looked solid and purposeful, and by sundown his back was aching with the satisfying pain of work he believed in.
Ruth found him washing his hands at the outdoor pump and asked why there was a little wall in the middle of the field. Eli explained that the stone was supposed to keep the ground cooler, and she listened without smiling at the parts he had not yet figured out. "Are you going to write down what you do?" she asked. When he said no, she went into the house and returned with a slim notebook whose cover had been torn from one corner.
"Your grandmother says you'll learn more from the parts that go wrong than the parts that go right," Ruth told him. "That only helps if you can remember what you tried." She found a pencil in her apron pocket and placed it on the notebook. Eli opened to the first blank page, wrote the date and the dimensions of his strip, and hesitated before recording the word experiment, which made the work feel more serious than he knew how to justify.
The next morning he checked the soil beneath one rock and found it cooler than nearby exposed earth. He felt vindicated, though when he returned in the afternoon the leaves nearest the stacked stones had drooped. He told himself the plants had already been weak and that the arrangement needed time to work. In his notebook he wrote, Cooler in morning, leaves still tired by evening, and underlined the first phrase harder than the second.
The first person outside the family to notice was a boy named Calvin Reese, who rode past on his bicycle while Eli was returning a load of stones to the barn. Calvin had once been in Eli's class, but he was older by a year and seemed to have learned how to turn almost any ordinary sight into a joke. He stopped at the roadside, pointed toward the strip, and asked whether Eli was building a graveyard for vegetables. Eli kept pushing the wheelbarrow, which Calvin apparently took as an invitation to make the story better by the time he reached town.
By the weekend, people were asking Thomas about his son's rock farm. A neighbor at the feed store told him that boys had wild ideas when they were not given enough work, and another offered to loan Eli a proper rake so he could undo the damage. Thomas endured the comments with his usual reluctance to discuss family matters in public. He came home tense, and when he saw Eli placing one more stone beside the beans, he called across the yard that they had agreed on ten feet, not the entire county.
