The children brought armfuls of moss and leaves, and scattered them over the hard rocky floor.
When the beds were finished they made a fireplace.
They dug a shallow hole just outside the cave and walled it around with stones.
Perhaps you would not call this a good fireplace, but it was the best fireplace any one had at that time.
