Diving is the art or act of descending into water to considerable depths, and remaining there for a time. The uses of diving are important, particularly in fishing for pearls, corals, sponges, examining the foundations of bridges, recovering valuables from sunken ships, and the like. Without the aid of artificial appliances a skilful diver may remain under water for two, or even three minutes and rarely longer. Various methods have been proposed and engines contrived to render diving more safe and easy. The great object in all these is to furnish the diver with fresh air, without which he must either make but a short stay under water or perish. Research Diving
