Hoop

The old cider cask had loosened over the dry months, its topmost hoop slipped down a finger’s width so that a thin seep darkened the wood below. Nyra set the cask upright on the cellar floor and tapped the loose hoop with a wooden mallet, driving it back up toward the narrow of the barrel where the staves crowded close. The girl crouched to watch the band of iron bite and hold.

“Why does knocking it upward make it grip?” the girl asked, turning the mallet over in her hands. “It seems you are only moving the ring, not changing the wood at all.”

“The staves are not straight, they curve out at the belly and draw in at the end,” Nyra said. “When I drive the hoop toward the narrow place, it has less room, so it must squeeze. The ring does nothing on its own. It only gathers the staves and will not let them lean apart.”

The girl pressed her palm to the side of the cask and felt how firm it had gone, how the seep had already stopped its slow dark crawl. She said it was strange that a single band could speak for every stave at once, keeping the whole round shape from any one plank giving way. Nyra nodded and set the mallet down.

Later, closing the day’s column in her book, Nyra wrote only that the cask was sound again and the cider saved. A book gathers what can be set down in a line and counted, and leaves the rest to the one who was there. The book keeps the measure, and you keep the tightening of it.
