This difficulty is in part obviated by the use of her braille machine, which makes a manuscript that she can read; but as her work must be put ultimately in typewritten form, and as a braille machine is somewhat cumbersome, she has got into the habit of writing directly on her typewriter. She depends so little on her braille manuscript, that, when she began to write her story more than a year ago and had put in braille a hundred pages of material and notes, she made the mistake of destroying these notes before she had finished her manuscript. Thus she composed much of her story on the typewriter, and in constructing it as a whole depended on her memory to guide her in putting together the detached episodes, which Miss Sullivan read over to her.
