Which rises o'er the source of Dee,

And from the eastern summit shed

Her silver light on tower and tree.

In every Prairie's midst; and where the bright

Enchanting stars shine pure through Southern night,

She still is there, the guardian on the tower,

To open for the world a purer hour.

Which stood four-square to all the winds that blew.
