Writing my opening letter of the school year, I quoted from Mark Twain's early piece Old Times on the Mississippi that originally appeared in, I think, The Atlantic Monthly. In reflecting on a reading of it long ago, I associated Twain's main character in Old Times with Tom Sawyer. However, I realize upon further reflection and research that it was in fact more autobiographical. The main character's identity is not so clear, but it's probably Twain himself. My apology for the error.
