Ballantyne went under water in a real diving dress to write this story of a young man who takes up the diver’s trade. His hero inspects sunken wrecks, works on harbour engineering and salvage, and is drawn into adventures with pirates in the China Sea, while the author explains helmets, air pumps and the history of diving along the way.
