Millay hits the reader with this powerful line that seems to contradict the line before where she says that death is not present. Her terminology here seems strikingly cold and exact about the rotting of a cadaver after death. But why specifically the brain? Perhaps Millay was being figurative again; under all of this fluff and prettiness that is spring (life?), that maybe people are letting their minds go to waste.
