After an evening of self-loathing and contrition, Emma resolves to call on Miss Bates first thing in the morning to try to set things right.
Emma calls on Miss Bates
I won't go into all the details, just the things of interest:
1) There's a scramble when she first arrives, and it's clear that Jane Fairfax does not want to see Emma Woodhouse. Emma is also left to worry for a few moments that Miss Bates is going to avoid her as well, but Miss Bates does no such thing.
2) We get a lot of information from Miss Bates. In fact, she provides a bit of an info dump, which is allowable because it's completely in character for her. Also, as a commenter pointed out in a comment to a previous post over at LiveJournal, Miss Bates's prattle provides quite a lot of information about Frank Churchill's story line.
a) The Eltons had a dinner party the night before, to which Emma was not invited. Miss Bates attended with her mother and her niece; Mr. Knightley did not attend, though he was invited.
b) Frank Churchill left town suddenly the night before, something they learned while at the Eltons.
c) After learning that Frank had left town, Jane Fairfax suddenly decided to accept the governess position that Mrs Elton kept
d) Jane has been sick and miserable since making that decision, but insists on proceeding.
Because Emma makes an effort to actually attend to Miss Bates and what she is saying, and because she is truly happy to be admitted to see Miss Bates after behaving so badly the day before, Emma is behaving as she actually ought to have been doing all along. And she finds it much easier to feel terrible for poor Jane Fairfax, who has made the decision to (nearly) go into service as a governess, and to find actual compassion for Jane, who she believes deserves something better.
This is an uneventful chapter as far as things go, which allows the reader to recover from the hubbub and horror of the Box Hill outing, but with so many events relayed, it's obvious that Jane Austen continues to stir the pot, and that things are going to kick up again soon.
