Boy Scouts in the North Sea The Mystery of a Sub

A PACKAGE VANISHES Good night! exclaimed a lad of about eighteen peering from the window in a railway coach. This train's running on a regular lake! What's that, Jimmie? asked a companion approaching the first speaker. Are we on a ferry? I still feel the wheels hit the rail joints.

It looks as if we're going out into the ocean! We can't be headed for Holland at this rate! We surely are! assured the one addressed as Jimmie. I'll bet I can tell you what that is!
