Bell noticed his expression and softened her voice. "That doesn't make the observation worthless," she said. "It means we're going to learn more if we separate the factors. The best growers I know are the ones willing to let the land disagree with them." She asked him whether he wanted to help her mark a few more comparison plots, and his relief was so sudden that he answered before she had finished the question.
They spent two hours examining the strip. Bell used a hand probe to compare soil conditions, checked the slope, and took notes on compaction, available organic matter, and crop stage. She explained that stone could reduce direct evaporation and protect certain surfaces from wind, but dark or tightly packed rocks could also increase heat or interfere with rainfall. The helpful effect depended on local conditions, and using too much stone could make future planting and cultivation difficult.
Eli wrote down every warning. Bell suggested testing a small additional area with carefully spaced stone, another with loose organic mulch, and a third managed without either, while keeping the planting and watering as consistent as possible. She encouraged him to track plant growth and eventual yield instead of relying only on how green the leaves looked. He realized that his original ten-foot idea had grown into an experiment he could explain to other people without embarrassment.
Before she left, Bell spoke privately with Thomas near the truck. Eli could hear only fragments, but he caught the phrases promising moisture retention, site specific, and do not scale too quickly. Thomas listened with his arms folded, then glanced toward the field. When he came back to the barn, he told Eli they had permission from the best kind of person to continue: someone who had shown them reasons to be careful.
Clara promised to return after the next significant rainfall, and she wrote down the office number in Eli's notebook. "If something surprising happens, call," she told him. "That includes bad surprises. We learn as much from an experiment that fails as we do from one that works." Eli watched her county vehicle disappear down the road and felt the strange confidence that comes from discovering your questions belong to a larger world.
A week later, a reporter named Helen Marsh called the farmhouse. She wrote for the county newspaper and had heard about a boy experimenting with stone mulch from someone at the extension office. Ruth answered, hesitated, and asked Eli whether he wanted to speak with her. He agreed only after making sure she was interested in the soil and not simply in photographing him dragging a wheelbarrow while people laughed.
Helen arrived on a bright afternoon carrying a notebook and a camera. She asked about the drought, the family's farm, and the first time Eli had noticed moisture beneath a stone. He showed her the failures before the successes, which surprised her enough that she asked him to repeat the story of the first drowned bean plants. Eli explained that the mistake mattered because it taught him to leave space for rain to enter.
