" Once upon a midnight dreary, while I pondered, weak and weary,  Over many a quaint and curious volume of forgotten lore,  While I nodded, nearly napping, suddenly there came a tapping,  As of some one gently rapping, rapping at my chamber door.  "'Tis some visiter," I muttered, "tapping at my chamber door—                           Only this, and nothing more. "
