I saw a mermaid sporting in the bay,
  Far down, far down where blew no roaring gale;
About her snowy shoulders flashed the spray,
  The waves played emerald at her sinewy tail;
She swam a jade and golden, star-set way,
Where all the rainbow colors seemed to play—
  She vanished at the Swedish captain's hail
  Who bid me go to Hell and furl a sail.
