The Banner Boy Scouts Afloat
The Secret of Cedar Island
George A. Warren
When a summer scouting expedition on motorboats leads to a supposedly haunted island, a group of resourceful boys uncover the surprising scientific work behind local legends.
In Short
During their summer vacation, the Stanhope Troop of Boy Scouts embarks on a river and lake expedition aboard motorboats. Led by assistant scout master Paul Morrison, the twenty-six energetic lads set up camp on Cedar Island, a remote spot shadowed by local rumors of a ghost and counterfeiters. Instead of supernatural terrors, they discover a reclusive professor conducting secret explosive experiments. Through quick thinking, practical jokes, and steady teamwork, the scouts navigate treacherous mud flats, floods, and hazards, returning home with matured judgment and deepened camaraderie.
The Story
The Stanhope Troop of Boy Scouts gathers in their thriving hometown for a new summer adventure under the leadership of young assistant scout master Paul Morrison. Preparing for an extended trip afloat, the boys load provisions, tents, and gear onto two motorboats named the Comfort and the Speedwell. Along the way, curious members like Bobolink and Jack Stormways speculate about mysterious boxes hauled off earlier by local wagons, while the troop handles minor navigational mishaps, including running aground in shallow, oozy river channels.
Reaching their destination, the scouts establish camp on Cedar Island, a lonely expanse long avoided by locals due to dark stories of a resident ghost and hidden criminals. True to their scout training, they post sentries and maintain watchful routines. Bobolink utilizes a clever hot-water pump contraption, heated on a kerosene cookstove, to deter local troublemakers who attempt nighttime pranks against the anchored boats. Despite this lighthearted and effective defense, an unsettling atmosphere pervades the island, heightened by strange nocturnal flashes, mysterious tracks in the brush, and the presence of a wild dog identified as Nuthin's former pet, Lion.
Sensing deeper secrets behind the island's bad reputation, Paul leads a carefully organized exploring party across the rugged terrain. The boys dodge thickets, observe local wildlife like cotton-tail rabbits and partridges, and maintain open communication with the main camp via signal flags and smoke codes. Their suspicions grow that the supposed ghost is merely a cover for human activity. Soon, a massive earth tremor shakes the region, triggering a landslide that dams the lake's outlet and causes water levels to rise rapidly around their camp.
Faced with mounting danger, the scouts secure their boats against the ferocious current and wait out the storm. The explosion that accompanied the tremor is revealed to be the work of an eccentric professor experimenting with advanced explosives in a secluded shack. When the natural dam finally gives way and the flood recedes, the professor is safely evacuated with the help of his assistants and the scouts. Expressing profound gratitude to Paul for saving his life, the professor departs, leaving the boys to conclude their summer vacation successfully before returning home to Stanhope via the river currents and canal.

What It's Really About
The book explores the formation of character through responsibility, resourcefulness, and outdoor stewardship. It examines how youthful imagination often transforms ordinary rural mysteries—like reclusive researchers, wild animals, or natural geological events—into ghostly legends. Beneath the lighthearted adventure, the narrative argues that true scouting is forged not just by winning banners or camping in the open, but by maintaining steady judgment, courage, and composure in unexpected emergencies. The story questions how young people handle leadership burdens, showing that real growth happens when boys transition from playful pranks to looking out for one another's safety during genuine peril.
Why Read It Today
Readers who appreciate classic juvenile adventure, wholesome camaraderie, and earnest coming-of-age stories will find much to enjoy here. Reading the book feels like stepping into a simpler, highly structured world of early twentieth-century youth organizations, complete with enthusiastic slang, strict troop hierarchies, and unshakeable optimism. Modern readers should be prepared for period attitudes, formal Victorian-esque narration from the author's introductory note, and dated dialogue reflecting early-1900s small-town life. Despite these period elements, the enduring charm lies in the genuine warmth between the boys, their inventive problem-solving, and the vivid depiction of river camping. It stays with you as a comforting, nostalgic snapshot of boyhood loyalty and cooperation.
