Personal experiences of a commercial diver, supplemented by anecdotal material from other divers' experiences. He tells of his early training and experiences, of equipment trouble, freezeups, air troubles, currents, traps, working with explosives, recovering bodies, adventures with fish, sponge and pearl diving, diving during the World War. It is a story of how to live dangerously and make a living at it. Shows the difference between commercial and government work. Readable -- though not in Ellsberg class.
