A thoroughly entertaining and instructive story of a wonderful river. As in all the volumes of this popular series, the boys meet with startling adventures, getting mixed up with river thieves and coming upon a mystery which trails along to the Gulf of Mexico with them. "Captain Joe," the white bulldog pet of the crew of the motor-boat, will be sure to make a hit.

SIX-RIVER MOTOR BOYS ON THE ST. LAWRENCE; or, the Lost Channel.

This is a thoroughly interesting and instructive story of a romantic voyage from the Gulf of St. Lawrence to Chicago, by way of the quaint old City of Quebec, the Thousand Islands, and the Great Lakes. It deals with historical characters to some extent, all of whom are woven into a strong plot which reaches from old Indian days to the present time. It is safe to say that the book will become the most popular of the series.

SIX-RIVER MOTOR BOYS ON THE OHIO; or, the Three Blue Lights.

This book deals with the strange and vagrant life on the Ohio River—the life lived by those who dwell in houseboats, storeboats, and shantyboats. The motor-boat boys become involved with Night Riders and Moonshiners, and the mystery of the Three Blue Lights supplies plenty of holding power. In this volume "Teddy," the pet bear, comes out strong at critical times.

SIX-RIVER MOTOR BOYS ON THE COLORADO; or, the Clue in the Rocks.

The story deals with a little-known stretch of river, from the Gulf of California to the Grand Canyon. The plot is a strong one, and the incidents grow naturally out of it. The clue sought is at last discovered by two venturesome lads who start out to have a "little fun of their own on the side." As in all other volumes of this series, the author—perhaps the best-known writer of boys' books in the country—tells something of the history of the country the boys pass through.
