"You brought the whole county's breakfast club into the field," she said. Eli looked up, surprised to hear her joking about a project she had treated with such quiet seriousness. She squeezed his shoulder and reminded him that a few worms and birds would not pay the bank. He agreed, but they both understood that something important had changed even if neither of them could yet put a price on it.
Thomas first acknowledged the difference on a day when he had no reason to be walking near the pear tree. He was carrying fencing staples toward the back pasture, and the shortest path led him past Eli's strip. The brighter leaves caught his eye, and he stopped with the tin of staples hanging from one hand. He crouched beside the center plants and pressed his thumb into the exposed soil between two stones.
Eli saw him from the barn and approached without speaking. Thomas lifted a pinch of earth, rubbed it between finger and thumb, and looked toward the surrounding field. "This is different," he said. Eli felt the sudden, ridiculous urge to explain everything at once, but he held back and let his father look.
"It might be the compost," Thomas added after a moment. Eli nodded, because he had been thinking the same thing. He showed his father the other comparison strips, one with stone alone, one with organic covering, and one left exposed. Thomas listened to the explanation and, when Eli finished, asked to borrow the notebook for the evening.
The request frightened Eli more than he expected. He had written the bad results alongside the good ones, including the day he had lost his temper and thrown his gloves into the wheelbarrow. There were smudges, rough sketches, misspelled words, and measurements he had crossed out when he realized he had taken them incorrectly. Still, he handed it over, because a notebook that showed only success would not be the record he had promised himself to keep.
Thomas read it at the kitchen table after the dishes were done. Ruth sat nearby mending a towel, and Nana Vera worked a crossword puzzle she had already completed once. Eli waited in the doorway pretending to be interested in the clock. His father turned each page carefully and sometimes went back to an earlier one before continuing.
"You measured the dry patch too?" Thomas asked. Eli nodded and said the comparison was not perfect because of the changing shade and soil. Thomas returned to the beginning and looked at the drawing of the first stone pile. "I remember this one," he said. "You were proud of how solid it looked."
