Read it through once

There was a small, heavily-grated, unglazed window high in the wall, with a stone screen before it, so that the sky could be only seen by stooping low and looking up. There was a small chimney, heavily barred across, a few feet within. There was a heap of old feathery wood-ashes on the hearth. There was a stool, and table, and a straw bed. There were the four blackened walls, and a rusted iron ring in one of them.
