Lewis E. Theiss 
The Young Wireless Operator–Afloat [EPUB ebook] 

To-day the American Merchant Marine commands the respect of the world, for in increasing numbers vessels flying the Stars and Stripes are seen on every sea.
That our boys may know more about the many experiences which such vessels encounter and to tell the story of how Roy Mercer made good as a wireless operator upon one of these vessels, is the purpose of the author in penning this story of life on the high sea.
