A wooden case or box in which the compass on board a ship is kept to protect it from injury. A light is placed within it at night to insure that its indications are seen. It is placed immediately in front of the wheel or steering apparatus, and secured to the deck, usually by metal stays. The after portion has glass windows, so that the compass is at all times visible to the helmsman, who stands at the wheel.
