Deep, deep, deep in the cool
Forest, by a mirror pool
Lives the silken swift,
Lives the marble gift,
With a spiral horn.

Someday you may see him pass
As a shadow; hear the grass
Bend his steps.  And hush!
Watch the poolside rushes
Parted by the horn.

The water burst as if a gale
Started from this golden nail,
Bids them part.  Then the sounds
Of horse and hound,
And in a moment, he is gone.
