Andiron
The girl knelt by the hearth and watched the logs resting above the stone, held up on two short iron bars with legs and an upright post standing at each front. She asked Nyra why the wood was lifted on iron at all, when it might lie flat on the warm stones and be done with it. Nyra knelt beside her and set a hand on the cool metal. “Those are the andirons,” Nyra said. “They hold the logs up off the hearth, and they are set there for a reason.”
The girl ran a finger along the black iron and frowned. “Wood burns well enough on the ground,” the girl said. “Why should a pair of iron bars make the fire any better?”
“Because the andirons let the air come under,” Nyra answered. “A fire needs air beneath it as much as a flame above it, and logs laid flat on the stone smother their own underside. Raised on the iron, the wood draws air along its whole length, and the heat gathers below and lifts into the room. The ash falls clear beneath, and the logs burn even and slow instead of choking in their own embers.”
The girl wanted the andirons written into the book, the two legs and the upright posts and the gap of air they kept beneath the burning wood. Nyra let her set it down, and watched the careful letters form. A book gathers what can be set down in a line and counted, and leaves the rest to the one who was there.
“You can set down the shape of the andirons and the height of them,” Nyra said, “but not the steady glow of logs that burn well, nor the warmth that fills a room on a long evening while the iron holds the fire up to the air.” The girl looked at the page, and then at the quiet shine of the metal in the firelight, and she understood. The book keeps the andiron, and you keep the glow of it.
