_The Rover Boys Under Canvas_

INTRODUCTION

MY DEAR BOYS: This book is a complete story in itself, but forms the
third volume in a line issued under the general title, "The Second
Rover Boys Series for Young Americans."

As mentioned in a number of volumes of the first series, this line was
started some years ago with the publication of "The Rover Boys at
School," "On the Ocean," and "In the Jungle," in which I introduced my
young readers to Dick, Tom, and Sam Rover. The volumes of the first
series related the doings of these three Rover boys while attending
Putnam Hall Military Academy, Brill College, and while on numerous
outings.

Having acquired a good education, the three young men established
themselves in business and became married. Presently Dick Rover was
blessed with a son and a daughter, as was also his brother Sam, while
Tom Rover became the proud father of twin boys. At first the four lads
were kept at home, but then it was thought best to send them to a
boarding school, and in the first volume of the second series,
entitled "The Rover Boys at Colby Hall," I related what happened to
them while attending this institution.

From Colby Hall the scene was shifted to Snowshoe Island, where the
lads went for a mid-winter outing. Here they ran into a most unusual
mystery, and helped an old lumberman to establish his claim to the
island.

In the present volume the boys are back at Colby Hall, but it is time
for the annual encampment of the military school, and soon they depart
for a brief season "Under Canvas." This is at the time of the World
War, and the lads get mixed up in the mystery surrounding a wrecked
submarine. What this led to, I leave for the pages which follow to
relate.

In conclusion I wish to thank my numerous readers for all the nice
things they have said about my books. I trust the reading of the
volumes will do all of them good.

Affectionately and sincerely yours,
EDWARD STRATEMEYER.
