Life Preservers

devices for the saving of life in case of shipwreck. Civilized nations require each ship to carry life belts sufficient with which to equip every passenger and member of the crew. They are constructed usually of cork inclosed in canvas. When one is buckled around the waist it is impossible for the wearer to sink. In fact, they are required bylaw to be buoyant enough to support the heaviest person with another clinging to him. There are other inventions, as pillows and india rubber jackets. Some ships are provided with what are known as cork mattresses or cork rafts, capable of floating three people. See Cork
