the Rover Boys on Ocean (Illustrated): a Chase for Fortune

is the second volume in the first Rover Boys series. Even before they get out of the first chapter, they have a run-in, literally, on the water with the sneak of Putnam Hall, Mumps. We saw lots of Mumps in the first volume and the evildoer Dan Baxter. The two of them, along with Dan's father, Arnold. The Baxter, aided by Mumps and other bad guys kidnap Dora Stanhope, and what follows is high adventure on the high seas.
