Angel spirits of sleep, White-robed, with silver hair, In your meadows fair, Where the willows weep, And the sad moonbeam On the gliding stream Writes her scatter'd dream: Angel spirits of sleep, Dancing to the weir In the hollow roar Of its waters deep; Know ye how men say That ye haunt no more Isle and grassy shore With your moonlit play; That ye dance not here, White-robed spirits of sleep, All the summer night Threading dances light?
