This hall which ran along the top storey of the north wing was presided over by the curator, Rottcodd, who, as no one ever visited the room, slept during most of his life in the hammock he had erected at the far end. For all his dozing, he had never been known to relinquish the feather duster from his grasp; the duster with which he would perform one of the only two regular tasks which appeared to be necessary in that long and silent hall, namely to flick the dust from the Bright Carvings.
