“Where?” asked the doctor.
“The Colorado?” hinted Alex.
“The Mississippi,” said Jule.
“The St. Lawrence,” declared Case.
“The Ohio,” Clay suggested.
“Or the Columbia!” Frank mentioned.
“That’s it!” they all cried. “The Columbia! And a larger boat, and no gold caverns, and no snakes!” added Jule.
The story of the adventures of the boys at the headwaters of the Columbia will be found in the second volume of the Six-River Motor Boat Club Series, entitled: “Motor Boat Boys on the Columbia; or, the Confession of a Photograph.”
