From a letter from STC to Wordsworth after writing The Nightingale: <br /> <br /> In stale blank verse a subject stale <br /> I send per post my Nightingale; <br /> And like an honest bard, dear Wordsworth, <br /> You'll tell me what you think, my Bird's worth. <br /> My own opinion's briefly this-- <br /> His bill he opens not amiss; <br /> And when he has sung a stave or so, <br /> His breast, & some small space below, <br /> So throbs & swells, that you might swear <br /> No vulgar music's working there. <br /> So far, so good; but then, 'od rot him! <br /> There's something falls off at his bottom. <br /> Yet, sure, no wonder it should breed, <br /> That my Bird's Tail's a tail indeed <br /> And makes it's own inglorious harmony <br /> Æolio crepitû, non carmine.<br /><br />Samuel Taylor Coleridge<br /><br />http://www.poemhunter.com/poem/about-the-nightingale/
