Not the Pilot by Walt Whitman Lyrics

Not the pilot has charged himself to bring his ship into port,
         though beaten back and many times baffled;
Not the pathfinder 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
         march for these States,
For a battle-call, rousing to arms if need be, years, centuries hence.
