I Who Can Say Where Echo Dwells? In Some Mountain-Cave, Methinks, Where The White Owl Sits And Blinks; Or In Deep Sequestered Dells, Where The Foxglove Hangs Its Bells, Echo Dwells. Echo! Echo! Ii Phantom Of The Crystal Air, Daughter Of Sweet Mystery! Here Is One Has Need Of Thee; Lead Him To Thy Secret Lair, Myrtle Brings He For Thy Hair-- Hear His Prayer, Echo! Echo! Iii Echo, Lift Thy Drowsy Head, And Repeat Each Charmed Word Thou Must Needs Have Overheard Yestere'En Ere, Rosy-Red, Daphne Down The Valley Fled-- Words Unsaid, Echo! Echo! Iv Breathe The Vows She Since Denies! She Hath Broken Every Vow; What She Would She Would Not Now-- Thou Didst Hear Her Perjuries. Whisper, Whilst I Shut My Eyes, Those Sweet Lies, Echo! Echo!
