Proud swaying pendant of a crystal chain,
    On fair Columbia's rich and bounteous breast,
With beaded lakes that necklace-like retain
    Heaven's stainless blue with golden sunlight blest!
What other land can boast a gem so bright!
    With colors born of sun and driven spray - 
A brooch of glory, amulet of might,
    Where all the irised beauties softly stray.
Ay, more - God's living voice, Niagara, thou!
    Proclaiming wide the anthem of the free;
The starry sky the crown upon thy brow,
    Thy ceaseless chant a song of Liberty.
But this thy birthright, this thy sweetest dower,
    Yon arching rainbow - Love still spanning Power.
