A real treasure hunt of the most thrilling kind, with a sunken Spanish galleon as its object, makes a subject of intense interest at any time, but add to that a band of desperate men, a dark plot and a devil fish, and you have the combination that brings strange adventures into the lives of the Bungalow Boys. THE BUNGALOW BOYS IN THE GREAT NORTH WEST. The clever assistance of a young detective saves the boys from the clutches of Chinese smugglers, of whose nefarious trade they know too much. How the Professor's invention relieves a critical situation is also an exciting incident of this book. THE BUNGALOW BOYS ON THE GREAT LAKES. The Bungalow Boys start out for a quiet cruise on the Great Lakes and a visit to an island. A storm and a band of wreckers interfere with the serenity of their trip, and a submarine adds zest and adventure to it.
