  • Lay me on an anvil, O God.

    Beat me and hammer me into a steel spike.

    Drive me into the girders that hold a skyscraper together.

    Take red-hot rivets and fasten me into the central girders.

    Let me be the great nail holding a skyscraper through blue nights into white stars.

    - Carl Sandburg, 'Prayers Of Steel'.
