INTRODUCTION
My Dear Boys: This book is a complete story in itself, but forms the fifth volume in a line issued under the general title, "The Second Rover Boys Series for Young Americans."
As mentioned in some volumes of the first series, this line was started years ago with the publication of "The Rover Boys at School," "On the Ocean," and "In the Jungle," in which I introduced my readers to Dick, Tom, and Sam Rover and their relatives. The volumes of the first series related the doings of these three Rover boys while at Putnam Hall Military Academy, Brill College, and while on numerous outings.
Having acquired a good education, the three young men established themselves in business in New York and became married. Dick Rover was blessed with a son and a daughter, as was likewise his brother Sam, while Tom Rover became the proud father of twin boys. As the four lads were all of a decidedly lively disposition, 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.
