This strange Dialogue awakened my Curiosity so far that I immediately bought the Opera, by which means I perceived the Sparrows were to act the part of Singing Birds in a delightful Grove: though, upon a nearer Enquiry I found the Sparrows put the same Trick upon the Audience, that Sir Martin Mar-all practised upon his Mistress; for, though they flew in Sight, the Musick proceeded from a Consort of Flagellets and Bird-calls which was planted behind the Scenes.
