Desc: Wonders of the Sea: Directed by J. Ernest Williamson. With J. Ernest Williamson, Richard Ross, Asa Cassidy, Lulu McGrath. The ocean depths are explored with the aid of a submarine chamber of Williamson's invention and a few hardy souls. The construction of the device is examined; but most of the footage is given to plant and animal life, a girl swimming among the coral growths, and two divers who encounter a moray and an octopus.
