The Motor Girls on Crystal Bay

In Short

Set along the New England seaside, this juvenile adventure follows high-spirited driver Cora Kimball and her close circle of friends as they spend their summer vacation at Crystal Bay. Operating their electric-outfitted motorboat, the Chelton, the girls combine leisure with a serious purpose when they discover that their friend Freda Lewis and her widowed mother are in danger of losing their rightful property. Conspirators seek to seize the land for industrial development, hiding behind a missing deed. Through boat races, summer storms, and late-night confrontations, the friends uncover the long-lost document and preserve the bay.

The Story

The narrative opens in Chelton, where Cora Kimball and her friends—twins Bess and Belle Robinson, along with newcomer Marita Osborne—are packing trunks for a summer holiday at Crystal Bay. Cora encounters Freda Lewis, a former acquaintance whose family has fallen on hard financial times. Learning that Freda and her mother are struggling, Cora arranges for Mrs. Lewis to manage their seaside bungalow, the "Motely Mote," giving the distressed family both employment and shelter.

Joining the girls at the coast are Cora’s brother Jack and his collegiate chums, who set up a neighboring camp. The center of the girls' summer routines is the Chelton, a modern motorboat equipped with novel electrical appliances for cabin cooking and a hot-water system fed by the engine's cooling jacket. Their aquatic outings soon intersect with local lore when they meet old Denny Shane, a retired fisherman. Denny owns a single red oar—a cherished relic from a past ice rescue involving Freda’s late grandfather, Len Lewis.

Beneath the pleasant surface of resort life, trouble brews. Speculators aim to erect a mill dam across the local creek, a project that would destroy the bay's natural shore and strip Mrs. Lewis of her waterfront property. A group of conspirators—led by men named Bruce, Moran, and Kelly—search for proof that Mrs. Lewis lacks clear title to her land. They attempt to bribe and intimidate old Denny to force his silence, while an accomplice known as "Confidence Kate" uses false messages to lure Freda away from her supporters.

Cora and her friends remain vigilant. They overhears the plotters scheming in the brush, race their motorboat against rival craft, and endure a sudden squall on the bay. The mystery reaches its peak one night near Denny's isolated shore cabin. When the conspirators corner the old fisherman to force his compliance, Cora and Marita rally to his defense. During the ensuing scuffle, the ancient red oar is accidentally broken in two. The impact shatters its hollow handle, revealing the missing land papers hidden inside by Len Lewis years before his death. With the legal title restored, the speculators are defeated in court, the shore is saved, and the friends conclude their vacation in triumph.

The People

• Cora Kimball: A tall, capable, and commanding young woman from Chelton who drives her own automobile and captains the motorboat Chelton. She acts as the group's natural leader, taking the initiative to shelter the Lewis family and investigate the plot against them.
• Bess Robinson: Cora's plump, lighthearted chum who frequently frets over her appetite and weight while maintaining a loyal devotion to her group of friends.
• Belle Robinson: Bess's twin sister, an elegant girl who favors calm waters and reliable comforts, yet routinely joins the circle on their coastal adventures.
• Freda Lewis: A timid, hardworking girl whose family faces eviction and financial ruin until Cora offers her mother employment at the bungalow.
• Denny Shane: A sturdy, gray-headed retired fisherman whose devotion to the memory of Freda's grandfather makes him the target of the land speculators.
• Bruce and Moran: Unscrupulous land speculators who scheme to construct a mill dam across the creek, using intimidation, bribes, and false titles to dispossess the widow Lewis.

In Its Own Voice

Before setting out for the coast, the girls find themselves buried under the sheer weight of their luggage.

"The center of the chamber was littered to overflowing with trunks, suitcases and valises, in various stages of being packed, and from them overflowed a variety of garments and other accessories of a journey."

During a tour of their motorboat, the young men express total surprise at the fully functional galley arranged by the crew.

"'Dishwater!' repeated Ed. 'You've got this down to domestic science all right.'"

Deep in the woods, old Denny Shane reflects on the constant presence of his deceased companion around his waterfront home.

"Ah, many's the good old talk we used to have--a talk of the old days."

What It's Really About

Behind its light summer leisure, the story investigates female self-reliance and the bonds of practical community. The narrative contrasts the productive solidarity of Cora and her friends with the predatory commercial interests represented by the land speculators. By managing their own transport, mastering mechanical equipment, and organizing their own household affairs, the young women demonstrate an operational independence that challenges early twentieth-century assumptions about youthful femininity. The central mystery—centered on a missing deed hidden inside an everyday tool of rescue—reinforces the idea that safety and justice depend on protecting vulnerable neighbors from legal and economic exploitation.
