a particular sort of bed-frame, suspended from the beam of a ship for the officers to sleep in between the decks. This contrivance is much more convenient at sea than either the hammocks or fixed cabins: being a large piece of canvas sewed into the form of a chest, about five feet long, and one foot deep, and from two to three feet wide. It is extended by a square wooden frame with a canvas bottom, equal to its length and breadth, to retain it in an horizontal position.
