I ought to apologize to the reader and to Miss Keller for presuming to say what her subject matter is worth, but one more explanation is necessary. In her account of her early education Miss Keller is not giving a scientifically accurate record of her life, nor even of the important events. She cannot know in detail how she was taught, and her memory of her childhood is in some cases an idealized memory of what she has learned later from her teacher and others. She is less able to recall events of fifteen years ago than most of us are to recollect our childhood. That is why her teacher’s records may be found to differ in some particulars from Miss Keller’s account.
