Henry Wadsworth Longfellow
Possibilities
Where are the Poets, unto whom belong
  The Olympian heights; whose singing shafts were sent
  Straight to the mark, and not from bows half bent,
  But with the utmost tension of the thong?
Where are the stately argosies of song,
  Whose rushing keels made music as they went
  Sailing in search of some new continent,
  With all sail set, and steady winds and strong?
Perhaps there lives some dreamy boy, untaught
  In schools, some graduate of the field or street,
  Who shall become a master of the art,
An admiral sailing the high seas of thought,
  Fearless and first and steering with his fleet
  For lands not yet laid down in any chart.
