I have seen the kicking feet and the two in black who now seize hold of them and drag downward with all their weight. I don't want to see it anymore. I look at the grass instead. I describe the rope. (42.27)
Even though the executions aren't something the narrator "want[s] to see [...] anymore," she still includes them in her story by describing a previous one. It's as though even though she doesn't want to watch what happens, she can't escape it. She still has to go to the Salvaging, and because she has to go, we have to read about it too.
