Horse blanket, anyone?

Reading O'Connor: Collected Works. From letter about revising her first novel:



"Enclosed is Opus Nauseous No. 1. I had to read it over after it came from the typist's and that was like spending the day eating a horse blanket. It seems mighty sorry to me but better than it was before. My mother said she wanted to read it again so she went off with it and I found her a half hour later on page 9 and sound asleep."
