“ LOCKER. Divisions in cabins and store-rooms.—Boatswain's locker. A chest in small craft wherein material for working upon rigging is kept.—Chain-locker or chain-well, where the chain-cables are kept; best abreast the main-mast, as central weight, but often before the fore-mast.—Davy Jones' locker. The bottom of the sea, where nothing is lost, because you know where it is.—Shot-lockers, near the pump-well in the hold. Also, the receptacle round the coamings of hatchways. ”
