Read this stanza from "Old Ironsides." What does the word "it" in the fifth line refer to? Ay, tear her tattered ensign down!
Long has it waved on high,
And many an eye hasdanced to see
That banner in the sky;
Beneath it rung the battle shout,
And burst the cannon's roar;-
The meteor of the ocean air
Shall sweep the clouds no more!
