Frank Reade, Jr.'s Search for the Silver Whale / Or, Under the Ocean in the Electric "Dolphin"

A young inventor builds an electric submarine modeled on fish physiology and, with his explorer companion, undertakes an undersea voyage aboard the electric craft. The narrative follows design and construction, a trial dive that uncovers a sunken wreck and provokes encounters with sharks and a whale, pursuit of a mysterious silver whale, discovery of a confession and a valley of pearls, and hazards such as storms, reefs, and temporary stranding before rescue. Episodes blend technical description, displays of inventive machinery, combat with sea creatures, and treasure-hunt elements, arranged as sequential adventure set pieces emphasizing ingenuity and perilous exploration.
