Many seamen and others who face dangers of being thrown into the sea from mined or torpedoed ships in the battle of the Atlantic may save their lives with a one-piece rubber suit which keeps the wearer warm and dry. Developed by the Norwegian government, and demonstrated recently from a dock in New York harbor, the waterproof suit, which may be inflated, is made like a sack that fits over the body and has a pair of boots attached for the legs. Sleeves end in water-tight elastic cuffs. When ready for use the suit stands folded down over the boots, and it may be put on in half a minute by stepping into the boots and pulling the suit upward until the hood covers the head. Life-saving vests are worn under the suits. In order to keep. the air jnside the suit from escaping and prevent water from entering at the neck, the hood is shirred with elastic and the string ties closely around the neck.
