The Radio Boys in the Thousand Islands

In Short

When three high school friends—Cub, Bud, and Hal—set out on a summer boat trip through the Thousand Islands, a series of mysterious radio signals draws them into a perplexing rescue mission. What begins as an apparent college hazing prank quickly escalates when they discover a real kidnapped student and run afoul of a dangerous gang operating along the border. Combining early wireless technology, quick thinking, and guidance from Cub's father, the boys navigate the labyrinthine waterways to unmask the perpetrators. The story endures as a lively artifact of early twentieth-century youth adventure, capturing the dawn of home radio culture.

The Story

School is out for the summer, and high schoolers Cub Perry, Bud Taylor, and Hal Stone are eager to test their newly acquired radio equipment on a vacation trip aboard the Catwhisker, a motorboat owned by Cub's father, Mr. Perry. Before they even set sail, the boys intercept a strange SOS signal from an operator claiming to be marooned on an island in the St. Lawrence River. A rival amateur transmission insists the broadcast is merely part of a collegiate wager, leaving the boys uncertain whether they are witnessing a joke or a genuine tragedy. Driven by curiosity, the trio persuades Mr. Perry to navigate the Thousand Islands to locate the mysterious signal origin.

Upon arriving near the remote cluster of islands, the boys discover that the truth is far more complicated than a simple prank. Through careful radio direction-finding and local inquiries, they trace the broadcasts to Friday Island. There, they discover evidence of a abandoned camp and learn that the marooned student, Raymond Flood, is actually Alvin Baker—Hal’s own cousin—who was kidnapped as part of an elaborate college hazing stunt by older sophomores. However, the situation worsens when the hazers themselves lose control of the island to a far more sinister force.

While exploring the island, Bud and Hal are confronted by four aggressive men who claim the territory as their own and demand that the boys leave. Led by a menacing figure known as "Captain" Howard, the men capture Bud and Hal, holding them prisoner while attempting to intimidate Mr. Perry and Cub. Armed with determination, their radio set, and a homemade catapult built by Bud, the rescuers push back. Cub uses the wireless system to alert local authorities and broadcast calls for assistance across the border, while Mr. Perry uses clever psychological pressure to interrogate captured members of the gang.

With the aid of Canadian law enforcement officer Mr. Buckley and Alvin’s father, the group gradually unravels the true plot. The men claiming the island are not merely hostile landowners; they are international smugglers using the secluded channels of the Thousand Islands to move contraband across the United States-Canada border. The college hazers had unwittingly dropped Alvin right into the middle of the criminal operation. Through coordinated radio communication, strategic boat searches, and steady nerves, the boys help the police round up the smuggling ring and safely rescue Alvin. With the villains in custody and the mystery solved, Mr. Perry initiates steps to purchase Friday Island as a permanent summer camp, leaving the boys to enjoy the rest of their vacation.

How It Unfolds

The voyage begins After finishing their school examinations, Cub, Bud, and Hal debate how to spend their summer vacation. Their debate is settled when their amateur radio setup picks up a mysterious SOS call from an operator claiming to be stranded on an island in the St. Lawrence River.

Tracing the signal Securing permission and passage on Mr. Perry's motorboat, the Catwhisker, the boys head into the Thousand Islands. They use radio direction-finding and evening weather forecasts obtained from local "hams" to narrow down the mysterious sender's location.

Exploring Friday Island The search leads the party to Friday Island, a densely covered piece of land isolated by shallow waters. Upon investigating the island's interior, they find a deserted camp, a discarded diary, and clues revealing that the stranded youth is Hal's cousin, Alvin Baker.

Confronted by trespassers While Mr. Perry is away, four suspicious men led by "Captain" Howard march into the camp and demand that the boys vacate the island. The confrontation escalates quickly, and the men take Bud and Hal captive to protect their secret hideout.

Calling for backup Cub avoids capture and uses the boat's radio outfit to send out emergency messages to Canadian amateurs and local police. Meanwhile, Bud uses a hand-crafted slingshot to defend himself, eventualities lead to the capture of key members of the hostile gang.

Unmasking the enterprise Under heavy questioning by Mr. Perry and police officer Mr. Buckley, the captured men reveal that their operation extends far beyond a simple college prank. The island is being used as a staging ground for a gang of international smugglers.

Resolution and recovery Working alongside Canadian authorities, the group locates Alvin Baker, dismantles the smuggling operation, and sees the criminals turned over to the courts. The boys re-establish their island camp to enjoy a peaceful end to their summer outing.

The People

• Cub Perry (Robert): The self-appointed leader and "dictator" of the trio. Opinionated, vocal, and fond of dramatic resolutions, Cub wants excitement and non-stop action. Through the ordeal, his quick radio work and growing discipline prove crucial to coordinating the rescue effort.
• Bud Taylor (Roy): Practical, steady, and mechanically gifted. Bud wants order and precision in his projects, whether tuning a radio receiver or assembling tools. His resourceful nature culminates in his crafting a functional hand-catapult that helps turn the tide against their captors.
• Hal Stone ("Tee-hee"): Quick-witted and lighthearted, Hal balances Cub's dominance with playful humor. When he discovers that the missing island prisoner is his own cousin, Alvin Baker, his objective becomes deeply personal, driving him to brave capture to ensure Alvin's safety.
• Mr. Perry: Cub’s father and the captain of the Catwhisker. He acts as the voice of adult authority, weather caution, and practical logic. He guides the boys through problem-solving steps using what he calls "mathematics" and psychological firm-handedness during interrogations.
• "Captain" Howard: The menacing leader of the gang occupying Friday Island. Wanting absolute privacy to conduct illegal operations, he uses intimidation and force against the boys, ultimately revealing himself as the head of a border smuggling ring.

In Its Own Voice

"You c'n change that now and call it static instead of noise since we've all become radio experts," smirked Cub with characteristic superiority.

Before setting out on the St. Lawrence River, Cub jokingly uses their new technical hobby to dismiss his friends' complaints about his loud personality.

"Moral: Whenever at a loss, do some broadcasting," suggested Mr. Perry.

Faced with a dead end on the river, Mr. Perry advises the boys to rely on their technology to gather information from the surrounding community.

"There's going to be some awful serious trouble for your outfit if that boy isn't returned," Mr. Perry went on, waxing fiercer and more fierce in his manner as he purposely worked up a towering rage for the sake of its effect on the boy on the cot.

Determined to break the silence of a young accomplice, Mr. Perry stages a dramatic display of anger to force a confession regarding Alvin's location.

What It's Really About

Beneath its narrative of boating and wilderness exploration, the book examines the transformative impact of early technology on youth autonomy. Wireless telegraphy is not presented merely as a gadget, but as an empowering tool that expands the boys' reach across geographical and political borders. The story contrasts the constructive, community-minded use of modern invention—represented by the amateur radio operators who network across the river—with its misuses, seen both in the irresponsible hazing by college students and the covert communication of criminals. At its core, the novel argues that technical knowledge, when paired with methodical logic, sound adult counsel, and civic responsibility, enables young people to confront real-world dangers and solve complex, unexpected problems.

Why Read It Today

The reading experience is fast-paced and uncomplicated, driven by brisk dialogue, dramatic chapter cliffhangers, and a nostalgic, optimistic tone. Modern readers should be prepared for period-specific elements, including casual youth banter that occasionally borders on sharp ribbing, heavily simplified explanations of technology, and rigid moral phrasing typical of early twentieth-century series fiction. Additionally, the dialect written for working-class characters and villains reflects the literary conventions of the 1920s. Despite these period traits, the book remains a charming, historically fascinating look at how a groundbreaking technology once captured the imagination of American youth.
