The teaching walks started before the light was fully up, which was when the soil read best. Tal had learned this from her own Trailwarden, who had learned it from the generation before her, which was how the Compact passed things: not through documents but through walks in the early morning with a child's hand in yours, pointing at what to see.
Four children this morning. She knew them by their footsteps in the dark before the path lights came on: Ori's careful deliberate step, the twins moving in the slightly offset rhythm they always had, the youngest, a girl named Pell, who had started the walk with her shoes in her hand and her feet in the dew-wet grass.
"Put your shoes on," Tal said.
"I like the cold," Pell said.
"I know. Put them on anyway. You need your feet for the whole day."
Pell put her shoes on with the philosophical acceptance of a child who had been told sensible things by adults long enough to understand that sensible things were usually right even when they were disappointing.
The agricultural zone ran along the south side of the commune's main settlement, where the slope gave the best drainage and where the soil had three generations of composting behind it. In the grey pre-dawn, the winter crops were dark lines against darker earth, and the irrigation channels caught what little light there was and held it. Somewhere to the north, the breakfast fires were already going: the smell of woodsmoke and the low sound of the water recyclers coming up to full morning pressure. The commune woke early because what it did required light, and the best light began before you thought it would.
Tal crouched at the edge of the third row and waited for the children to gather around her.
"Touch here," she said, and placed her palm flat in the soil between the plants. "And here." She moved two rows over, to the patch she had been watching for ten days. "Tell me what's different."
Ori crouched and pressed both hands into the two patches in turn, his face going through the process of perceiving something he didn't yet have words for. "The second one is wrong," he said.
"Wrong how?"
"Too..." He searched. "Too packed. But it isn't packed. It just feels packed."
"Yes," Tal said. "That's right."
"Is it the Bloom?"
"Beginning of it, maybe. Not settled yet." She kept her hand in the Bloom-touched soil. The difference was not dramatic: a slight resistance, a missing give. The living soil had a quality of responsiveness, of something ongoing in it. The Bloom-touched patch felt like it had been interrupted. "What else?"
The twins had each taken a patch and were comparing notes in their low-voiced twin manner, which was faster than one person thinking. "No worms," one of them said. "The normal soil has worms."
"The Bloom-touched soil doesn't kill them," Tal said. "They leave. They know before we do, usually. That's why we check for worms first and the texture second." She stood and brushed the earth from her hands. "What does that tell you about reading a place?"
"You look for what's missing," Ori said. "Not what's there."
"Good."
Pell had drifted to the edge of the irrigation channel that ran beside the third row, watching the water. She had the quality of attention that certain children had, the kind that looked like distraction but wasn't.
"It's moving slower here," she said.
Tal came and stood beside her. The channel's current was slightly sluggish near the Bloom-touched section, not dramatically, but enough. The Bloom affected the soil's relationship with water in ways the Compact had observed for decades without fully explaining: Bloom-touched soil held water differently, and channels near it moved as if working harder for less distance.
"What does the water do when it doesn't want to go somewhere?" Pell asked.
"It doesn't want or not-want," Tal said. "Water doesn't decide. It moves according to what it is."
"But it's going slower."
"It's responding to what's in the soil. The soil is different, so the water moves differently. It's not making a choice. It's being what water is in the conditions it finds."
Pell considered this with her eyes on the water. "That doesn't seem right. The water seems like it knows."
"It does know," Tal said. "That's different from deciding. The river knows everything about itself. It knows the lowest place and it goes there. That's not a decision; that's what a river is. That's the river being completely itself."
"What if the lowest place floods?" Ori asked. He had come to stand with them at the channel's edge.
"Then it floods. And then it finds the new lowest place." Tal watched the water for a moment. "The question you're asking is whether the river should fight against going somewhere difficult. But a river that fought gravity would stop being a river. It would be water sitting still, getting warm and bad."
"We don't fight," said one of the twins, as an observation.
"We try not to. We try to know what we are and move accordingly." Tal looked at the channel. "That's different from not working hard. You've seen a rapids. That's the river working as hard as anything works. It's working with what it is, not against it. The effort is real. What's different is the direction."
They walked on, into the further rows where the winter squash was coming in heavy. The sky was lightening properly now, the east edge going from deep blue to a pale grey-gold. One of the twins found a patch of healthy soil near the water channel and pressed her face close to the earth and announced that she could smell the difference, which Tal confirmed was true: Bloom-touched soil had a particular flat quality to its scent, a smallness, while the living soil smelled of everything working.
"How did the Bloom get here?" Ori asked, gesturing back toward the affected rows.
"It came from the north," Tal said. "There was a settlement there before we were here. It went dark the winter before my grandmother was born. The Static pooled there for years before the Compact started planting." She paused. "We'll work that soil back eventually. We've been working it for forty years. It's better than it was."
"How long does it take?"
"As long as it takes. You don't argue with the Bloom. You tend the ground next to it and let the health spread. The worms come back when the conditions are right. You can't make the conditions right by insisting on them."
Pell had her face turned upward.
She stopped walking and pointed up without speaking, which was the way she pointed at things she wasn't sure about. The others looked. The drone was sixty meters up, a small dark shape moving in a careful arc that had nothing random in it. CAD survey markings, visible even at this distance. The drone made its slow pass with the consistency of a machine given a task and left to complete it.
"It's a survey drone," Tal said.
"CAD?" Ori asked.
"CAD."
"Are they looking for us?"
"They know where we are." She watched the drone for a moment. "They've always known where we are. We don't hide. There's nothing to find."
"Do they come here? The CAD people?"
"Sometimes. Traders mostly. Sometimes census people. We're in their records as a settlement of approximately ninety people, a self-sustaining commune, non-corporate designation." She watched the drone complete its arc and begin the next. "They have a category for us."
"What's the category?"
"Unplugged Commune. Self-Sustaining Subcorporate Settlement." She let this sit for a moment. "That's the part of us that's easy to write down."
The drone passed on, its line carrying it east over the commune's outer edge and toward whatever the next point was on its circuit. It would log their location, their approximate numbers, the state of the agricultural zone. Tomorrow it would return or another one would.
"The river is in no one's records," Tal said. "But it still knows where the lowest place is."
Pell had not followed the drone with her eyes. She had turned back to the channel.
"It's slower there too," she said. She was pointing farther along the south edge, past the rows they had walked, toward where the channel curved to follow the slope's contour.
Tal walked to where Pell was pointing and crouched and pressed her fingers into the soil beside the water.
The resistance was faint, not what she had felt in the third row, not settled, just the first interruption. The first absence of something that should have been there. Not much. Not yet. But enough.
She looked back at Pell, who had not moved, who was still watching the channel with the attention that looked like distraction but wasn't.
"Good," Tal said quietly. "Show me where else."
They worked along the south edge for another twenty minutes, Pell pointing and Tal checking, marking the new Bloom boundary in her mind for the afternoon meeting. The morning was fully light by the time they finished. Ori crouched at the edge of the last section they checked, pressing his fingers into a patch well back from the water's edge.
"This one's clean," he said.
"Yes. What does clean feel like?"
He thought about it with the careful deliberateness that was his nature. "Like something's living in it."
"Good," Tal said. "Remember that. You're not looking for the absence of the Bloom. You're looking for the presence of life. The Bloom is easier to see than the health is. That's true of most things." She stood. "When you learn to see the health, you've learned the harder thing."
The sun was fully up, the first real light catching the tops of the winter squash and the water in the channels and the damp earth between the rows, everything going from grey to the warm colors of early morning in the growing zone: the orange-brown of composted soil, the green-grey of the squash leaves, the silver of the moving water.
Pell had her shoes off again. She was standing at the channel's edge with her feet in the dew-wet grass, watching the water move.
"It knows," she said, quietly, to the water or to herself or to whatever she was thinking about.
Tal did not correct her.
