Leaves of Grass

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.
