Chapter 78 What the Walker Spent

The confession came, as confessions do among keepers, not when asked but when hiding cost more than telling. Ivo had been watching for a week — watching the way he watched anything alive, which was to say with an attention most people reserved for scripture — and on the seventh evening he sat down beside the slate on the eastern terrace with two mugs of barley tea, set one where a hand might take it if hands took things, and said: "You're spending faster than you told us. I've seen hearts run out before. My ship carried one sixteen hundred light-days to keep another heart company." He nodded at the fields breathing their slow gold under the lamps. "How long?" The band held its colors very still. Then the Walker wrote, small, the way people write things they have practiced not saying: *Nine seasons. Four, if the winters bite.* The council that convened in the tally-house that night was the strangest in the Ford's history: elders and engineers around one table, tally-keepers and star-sailors sharing benches, the Walker itself kneeling in the doorway because it did not fit indoors, its slate propped against the jamb where all could read it. The facts stood up and introduced themselves plainly, because plainness was mercy now and everyone in the room had survived worse than numbers: the fields depended on the Walker's metering — irrigation, lamplight, the count that ordered four billion hectares of night; the villages could no more run that scale than fly; and the Walker's core was a closed charge, made by its makers for one long job, drinking no wind and no sun, spending itself the way the heart of the last garden was spending itself, the way every kept thing in creation spends. "We can't recharge it," Pell said. "There's nothing on this world that speaks its current. I've had the core housing open twice this week — with permission," she added, at the Walker's slate, which inclined graciously, "and it's not a fuel problem, it's an architecture problem. The charge is laid down in the metal like grain in wood. You'd have to re-grow it. That's maker's work, and the only maker's hand I've ever heard of that's still warm is sitting on a hill at the rim of this sky." "There is somewhere, then," Sira said slowly, and the room turned. "A place where hearts are built. Where a heart older than every human institution is patched generation over generation by the one hand qualified to hold the pattern. The Eldest Gardener built the hearts." She looked through the doorway at the kneeling dark shape against the stars. "The first garden sits on retained warmth, and the craft that tends the oldest heart in existence is sitting on it." "Eleven days out," Elani said, from memory, because navigators keep such numbers where other people keep their children's names. "Eleven days back. Margin thin but kind." Voices argued every way after that, because forty-one springs of green were on the table and nobody pretended the arithmetic was gentle. One of the elders wanted to know whether a mended Walker came back different, the way mended people sometimes did; the Walker wrote *I will be whatever walks back,* which settled him more than any reassurance would have. A tally-keeper asked what happened if the ship was lost on the voyage, and Elani answered honestly — margin thin but kind — and the room held the honesty without breaking, because these were shelter-people, raised on the arithmetic of barely. And against it all stood the cost Ashe named before any sky-person could soften it: "You take our gardener away, and the fields go untended through the winter." Her voice didn't rise; she was a speaker; she weighed. "And I'll tell you what we weigh it against, Chief Archivist from the sky. We kept a tally of nothing for six generations and we kept it anyway. We watered by a rhythm we didn't understand because a machine taught it to our great-greats and we trusted the teaching. If the Walkers taught us anything in forty-one springs, it's that keeping doesn't wait for perfect conditions. So teach us the rota. Leave us your manuals. Give us a season to learn beside it before it goes — and then let it go to be mended, because a kept thing dies when no one keeps it, and we intend to keep ours." They spent nine days learning. Pell wrote the rota; the Walker dictated, in lines of light, forty-one years of field-craft compressed into a week of nights, and Tam and the Ford's tally-keepers took it all down in parallel, ink and crystal, completeness cheaper than selection. The tally-house smelled of lamp oil and cold tea past midnight; children who were supposed to be asleep copied irrigation tables into practice books by candle-end; Cass reorganized the intake shelf three times and defended each system to Tam with the fervor of a convert, and Tam, to his own visible surprise, conceded twice. The Walker watched its life's work being handed over with its band dimmed low, the way its kind dimmed respect, and corrected exactly one entry in nine nights — a winter lamplight figure for the western terraces — and let every other number stand because it had taught the Ford well enough to be checked. Two of the Song's engineers volunteered before the question finished forming to stay the season and see the villages through the handover, and their names went into both archives with the word *kept* written after them. And on the ninth morning the Walker consented to the voyage — consented formally, in writing, with the whole Ford assembled — and then paused, slate lifted, and added a postscript that made Sira's chest hurt: *I have never seen the makers' eldest. Tell it the rear-guard held.* It was loading-day evening, crates and cradles and the whole village hauling, that a girl from the tally-house tracked Tam down between the lander and the grow-bays: fifteen years old, ink to the elbows, the Ford's best young counter, named Cass, whom Tam had been trading catalogue errors with all week like contraband. She carried a copy-sheet and stood in front of him with the particular stiffness of a person doing the correct frightening thing. "The Walker let me collate its vault logs," she said. "For practice. There's an entry I can't close. Unit status roster, second sowing, seven of seven — six accounted. But the seventh isn't marked *spent* or *dark* or any ending-word at all. It's marked *tending,* and the location column gives co-ordinates, and the co-ordinates aren't on Earth." She turned the sheet so his lamp caught it. "Tam. Whatever the numbers say is out there — it's still working. And nobody has ever been to ask it the time." ---
