Beach comber \Beach comber\ [Written also {beach-comber}.]
   (Naut.)
   A vagrant seaman, usually of low character, who loiters about
   seaports, particularly on the shores and islands of the
   Pacific Ocean.

         I was fortunate enough, however, to forgather with a
         Scotchman who was a beach-comber.        --F. T.
