Tom, and Sam and their friends during an outing on one of our great
rivers,--an outing full of excitement and fun and with a touch of a
rather unusual mystery. During the course of the tale some of the old
enemies of the Rover Boys turn up, but our heroes know, as of old, how
to take care of themselves; and all ends well.

In placing this book into the hands of my young readers I wish once
more to thank them for the cordial reception given the previous
volumes. Many have written to me personally about them, and I have
perused the letters with much satisfaction. I sincerely trust the
present volume fulfills their every expectation.

Affectionately and sincerely yours,

ARTHUR M. WINFIELD.
