Boy Scouts in a Submarine

In Short

G. Harvey Ralphson’s Boy Scouts in a Submarine is an early twentieth-century naval adventure tale tracking the young members of the Black Bear Patrol as they embark on a high-stakes salvage operation in the South China Sea. Led by the remarkably capable youth Ned Nestor, the boys navigate the Pacific aboard a custom submarine to recover a sunken shipment of government gold and missing diplomatic papers off the coast of China. Blending period technology with espionage, the narrative reflects the era’s fascination with sub-sea exploration, American resourceful patriotism, and the quick-witted bravery of youth facing adult villainy.

The Story

The adventure opens in New York City, where the lively members of the Black Bear Patrol—Ned Nestor, Jimmie McGraw, Jack Bosworth, and Frank Shaw—learn of their next assignment. Government authorities have recruited Ned to pilot an experimental submarine, the Sea Lion, on a secret mission to the Gulf of Tonkin. There, a sunken American mail steamer rests on the ocean floor, holding a fortune in sub-treasury gold and a sealed packet of diplomatic papers that could trigger international conflict if seized by foreign revolutionaries.

Complications arise immediately when Captain Moore, an arrogant Secret Service official assigned to supervise the mission, insults the boys and insists on replacing the Sea Lion with his own craft, the Diver. Tensions escalate further near Mare Island Navy Yard in California, where a mysterious intruder attempts to sabotage the Sea Lion and an unidentified assailant nearly kills Lieutenant Scott, an officer assisting the scouts. Recognizing that conspirators are attempting to derail the expedition from within, Ned and his companions set sail across the Pacific, housing the Sea Lion inside a covert, floating dry dock towed behind a larger vessel.

Upon reaching the Taya Islands near the Gulf of Tonkin, the scouts submerge to search the ocean bed. They soon discover they are not alone: the rival submarine Diver—renamed or accompanied by a rogue vessel called the Shark—is already lurking nearby. Driven by greed and treason, Captain Moore and his treacherous son Arthur have partnered with rogue actors to loot the wreck for themselves. Undeterred by the dark depths, Ned, Jack, and Frank don diving suits to explore the tilted cabin of the sunken steamer, while Jimmie remains aboard to keep vigil over the lines and air hoses. Deep-sea horrors, including a giant sea serpent that coils around Jimmie during a floor-walk, test the boys' physical endurance and tactical focus.

Through quick thinking and close hand-to-hand combat, the scouts defend their submarine against multiple boarding attempts. Jimmie captures Arthur Moore when the young conspirator sneaks into the airlock, and Ned later disarms Captain Moore after the disgraced officer tries to crash the Sea Lion onto a rocky beach. Having subdued the main instigators, the scouts track down the crippled Shark, board her, and recover the critical diplomatic papers before towing the pirate vessel toward Canton.

With the treasonous conspiracy exposed and the papers safely handed over to the captain of an American warship, the boys wrap up their sub-sea campaign. Though the sunken gold remains temporarily on the ocean floor for future recovery, Ned’s team successfully shields the United States government from an international crisis. Their success earns them their next assignment: riding motorcycles inland toward Peking to hunt down the remaining diplomatic conspirators.

How It Unfolds

The voyage begins The Black Bear Patrol gathers in their New York clubroom to inspect maps of the Far East and learn about their upcoming government mission. Tensions flare when Captain Moore, a disdainful Secret Service officer, insults the Boy Scouts and tries to force them to use his own vessel instead of their trusted submarine.

Sabotage at Mare Island While preparing the Sea Lion for its Pacific transit at the California navy yard, an unknown intruder tampers with the submarine's machinery and leaves behind subtle physical evidence. A local officer is left near death in the attack, prompting Ned and Jimmie to pursue clues on shore despite an awkward run-in with a skeptical local policeman.

Probing the ocean floor After crossing the Pacific inside a hidden floating dry dock, the scouts deploy the Sea Lion into the waters near the Taya Islands. Ned and his friends put on diving suits to search the tilted, eerie wreck of a sunken mail steamer, only to realize that a rival submarine is already prowling the same waters.

Danger in the deep While exploring the ocean bed alone, Jimmie finds himself wrapped in the deadly coils of a giant sea serpent. Exercising remarkable presence of mind under pressure, the young scout uses his diving knife to sever the monster's spinal cord and escape before his air hose breaks.

Trapping the conspirators A series of tense encounters culminates inside the Sea Lion when Arthur Moore sneaks aboard to sabotage the vessel, only to be lassoed and held at gunpoint by Jimmie. Soon after, his father, Captain Moore, attempts to wreck the submarine on a shoreline but is overpowered by Ned and locked in a cabin alongside his son.

Capturing the Shark Ned leads a bold night raid onto the platform of the crippled enemy submarine, forcing its crew to surrender the stolen diplomatic packet under threat of piracy charges. The scouts take the rogue crew prisoner, secure the documents, and tow the damaged vessel toward open waters.

Safe harbor at Canton Navigating up the inlet toward Canton, Ned turns the prisoners and the recovered diplomatic papers over to the commander of an American warship. With the naval operation officially concluded, the boys prepare to trade their submarine for motorcycles to pursue the remaining plotters inland.

In Its Own Voice

"The answer?" Jack said, after peace had been in a measure restored, "I thought everybody knew that the Chinks wash their clothes in the Gulf of Tong King and hang them out to dry on the mountains of Kwang Tung! Are we going there, Ned?"

Jack Bosworth jokes with his fellow patrol members in their New York clubroom as they inspect maps of their secret destination.

He seemed to feel the slimy skin of the deep sea terror slipping through his waterproof suit, although his common sense told him that such could not be the case.

Jimmie McGraw battles rising panic on the ocean floor as a giant marine serpent wraps itself around his diving suit.

"Talk about the luck of the British army!" roared Jack. "It is blind adversity to the luck of the Boy Scouts! Here we've got the pirates bunched!"

Jack celebrates on the deck after Ned successfully boards the rival submarine and traps its rogue crew.

What It's Really About

Beneath its pulp-adventure framework, Boy Scouts in a Submarine centers on the tension between youthful integrity and adult corruption. The novel contrasts the self-discipline, resourcefulness, and loyalty of the Boy Scouts with the moral decay of figures like Captain Moore, who abuse positions of official trust for personal gain.

The story also reflects early twentieth-century American anxieties surrounding international diplomacy, maritime power, and technological warfare. By placing advanced machinery—the electric submarine and heavy diving gear—into the hands of teenagers, the narrative argues that technical mastery paired with civic virtue is the ultimate defense against foreign intrigue and internal treason.

Why Read It Today

This novel offers modern readers a vivid look into the early industrial fiction that captured the imaginations of young readers in the 1910s. Fans of retro-futurism, classic naval lore, and vintage juvenile fiction will appreciate its straightforward momentum, inventive maritime set-pieces, and period focus on sub-surface mechanics.

The reading experience is fast-paced and unsubtle, driven by snappy dialogue and clear moral boundaries. However, readers should approach the text aware of its historical context. The prose contains archaic slang, dramatic melodrama, and the colonialist period attitudes common in early twentieth-century popular fiction, particularly in its simplistic depiction of foreign locales and native populations.

Despite these dated elements, the book's genuine enthusiasm for invention, undersea exploration, and steadfast camaraderie retains a distinct historic charm. It stands as a memorable artifact of an era when the bottom of the ocean represented the ultimate frontier for adventurous youth.
