Classic Poem

I am the dancer of the wood —
I shimmer in the solitude;
Men call me Birch Tree, yet I know
In other days it was not so.
I am a Dryad slim and white
Who danced too long one summer night,
And the Dawn found and prisoned me!
Captive I moan my liberty,
But let the wood wind flutes begin
Their Elfin music, faint and thin,
I sway, I bend, retreat, advance,
And evermore — I dance! I dance!
