The River That Goes Up

The boat had not moved in two hours, and the sky was the wrong kind of empty.

"It rained every single afternoon," Maya said. "Five days. Same time. Then today, nothing."

Soren looked up from his notebook. "Maybe it just isn't going to."

"It is, though." Maya was watching the trees, not the sky. "Look at them."

Aunt Priya was crouched over a tray of leaf samples at the front of the boat, muttering numbers into a recorder. She had told them twice already that she could not talk until she finished logging. So they were on their own with the heat and the green wall of forest leaning over the water.

Soren followed where Maya was looking. The leaves were not still. Even with no wind, the top of the canopy shimmered, like the air over a hot road.

"That's just heat," he said.

"Heat coming off the leaves?" Maya tilted her head. "Or coming out of them?"

Soren stopped. He pressed his palm flat against the closest big leaf hanging over the rail. He held it there. When he pulled his hand back, the skin was damp.

"It's wet," he said. "But it hasn't rained since yesterday."

"So where's the water from." Maya was already pulling a clear sandwich bag out of her pocket, the kind she carried for exactly this reason. She slipped it over a cluster of leaves and twisted the open end shut around the stem.

"What's that supposed to do?"

"Catch it."

They waited. Soren wrote down the time. He wrote down that the sky was clear, that the air felt thick enough to drink, that one bag was now hanging off a tree like a strange fruit.

While they waited Maya did the thing where she went quiet and counted on her fingers, which meant a list was running in her head. Soren knew not to interrupt it.

"Five afternoons of rain," she said finally. "No rivers feeding clouds out here. No ocean close enough. So the rain has to come from something that's already here."

"The river," Soren offered.

"The river's right there and it's not making clouds." She pointed at the brown water, flat and patient. "It's the trees. Has to be. They're doing something."

Soren wanted to test it before he believed it. That was always his part. He checked the bag.

The inside had gone foggy. Tiny beads of water clung to the plastic where there had been nothing fifteen minutes ago. A thin film was already pooling at the twisted bottom.

"It's sweating," he said.

"It's breathing," Maya said.

They looked at each other. They were both right and they both knew it.

Soren did the math out loud, slowly, because that was how he made things real. "One leaf made that much. In fifteen minutes." He looked up at the canopy, which went on past the boat, past the next bend, past anything he could see. "How many leaves are out there."

Neither of them could finish that number. There was no finishing it.

"Aunt Priya," Maya called. "How much water does one tree put out in a day?"

Priya did not look up from her tray. "A big one? Hundreds of liters. Some of them, close to a thousand." She said it the way you'd say the time. Then she went back to her numbers, missing entirely the thing she had just dropped into the boat.

Soren put his pen down.

A thousand liters. From one tree. And then he tried to do what Maya had already done in her head, which was to stack tree on tree on tree across a forest the size of a country, every one of them breathing water into the air all day, all of it rising.

"It goes up," Maya said softly. "All that water goes up."

"And it has to come down," said Soren.

They both turned and looked at the sky, the empty sky, and now it did not look empty. It looked like a ceiling over a kettle that had been on too long.

"That's the rain," Maya said. "The trees breathe out the water. The water makes the clouds. The clouds rain on the trees. The trees breathe it out again." She turned in a slow circle, taking in the whole green wall. "It's a loop. The forest is making its own weather. It's been raining on itself for, for"

"Millions of years," Soren said. He wrote that down and his hand was not quite steady. "There's a river up there. A whole river, going the wrong way. Going up."

"And nobody built it," said Maya. "If you cut enough of them," Soren said slowly, working it like a knot, "there'd be less breathing. Less water going up. Fewer clouds."

"Less rain," Maya finished. "On the trees that are left."

"So they'd dry out."

"And breathe less."

They stopped. The loop ran the other way just as easily, and they had found that too, sitting on a stuck boat with a sandwich bag.

Priya finally clicked off her recorder and stretched. "You two still bored back there?"

"No," they said together, and did not explain, because there was no fast way to say what they were holding.

The light changed first. Not a cloud yet, just a softening, the blue going pale and high. Then, far off over the canopy, the first gray began to gather where minutes ago there had been nothing at all, building out of air that the trees themselves had filled.

The air pressed down, cooler now. Somewhere upriver the canopy began to hiss.

Maya untwisted the bag and tipped it. A thread of water, drawn out of a single leaf by nothing but the tree's own breathing, ran off her fingers and fell back into the brown river below.

Then the first fat drops hit the deck around them, one, two, then too many to count, exactly on time.
