Answer:
You heart it speak, for it has a hard tongue. But it cannot breathe, for it has not a lung.
I always run but never walk, I sometimes sing but cannot talk, No head on which a hat to place, You always look me in the face.
At night I come without being fetched. By day I am lost without being stolen.
By Moon or by Sun, I shall be found. Yet I am undone, if there's no light around.
What flies forever, Rests never?
They are many and one, they wave and they drum, Used to cover a state, they go with you everywhere.
