The City: Oakland #1
One-Man Sub Plays with Fish.
Oakland -- A one-man submarine, which tests gas, carried its inventor, James Bolar of Oakland 15 feet below the surface of Oakland Estuary is the newest in towed playthings. Its just like a glider, except that its different. A plane tows a glider aloft. A motorboat tows the submarine, an Bolar, laying flat in the diver, with his head looking out thru the conning tower, operates levers to keep his craft cavorting below the surface. "I got the idea while laid up with a broken leg in Honolulu Hospital", he says. The craft is ten feet long. (1933)
