NOT the pilot has charged himself to bring his ship into port, though
 beaten back, and many times baffled;
 Not the path-finder, penetrating inland, weary and long,
 By deserts parch'd, snows-chill'd, rivers wet, perseveres till he
 reaches his destination,
 More than I have charged myself, heeded or unheeded, to compose a
 free march for These States,
 To be exhilarating music to them--a battle-call, rousing to arms, if
 need be--years, centuries hence.
