Under Poem by Carl Sandburg

I
I am the undertow
Washing tides of power
Battering the pillars
Under your things of high law.

II
I am a sleepless
Slowfaring eater,
Maker of rust and rot
In your bastioned fastenings,
Caissons deep.

III
I am the Law
Older than you
And your builders proud.

I am deaf
In all days
Whether you
Say "Yes" or "No".

I am the crumbler:
To-morrow.
