The way in which Miss Keller wrote her story shows, as nothing else can show, the difficulties she had to overcome. When we write, we can go back over our work, shuffle the pages, interline, rearrange, see how the paragraphs look in proof, and so construct the whole work before the eye, as an architect constructs his plans. When Miss Keller puts her work in typewritten form, she cannot refer to it again unless some one reads it to her by means of the manual alphabet.
