Upon the silver beach the undines dance With interlinking arms and flying hair; Like polished marble gleam their limbs left bare; Upon their virgin rites pale moonbeams glance. Softer the music! for their foam-bright feet Print not the moist floor where they trip their round: Affrighted they will scatter at a sound, Leap in their cool sea-chambers, nibly fleet, And we shall doubt that we have ever seen, While our sane eyes behold stray wreaths of mist, Shot with faint colors by the moon-rays kissed, Floating snow-soft, snow-white, where these had been. Already, look! the wave-washed sands are bare, And mocking laughter ripples through the air.
