In the beginning of June, Miss Agatha (that's Levin's old nurse and current housekeeper) sprains her wrist.
The district doctor stays to dinner and is awed by Koznyshev, who is delighted to have a new audience for his ideas.
For his part, the doctor tells Koznyshev all the district gossip, and complains about the bad state of the District Council (remember, that's the administrative unit that Levin quit because he thought it was a waste of time).
Afterwards, Koznyshev is in a stellar mood and wants to go off and fish. (Koznyshev likes to make a point of the fact that he enjoys fishing.)
Levin offers to drive his brother there in a cabriolet (which is a light, two-wheeled, one-horse carriage that can sit two people).
Levin chats with an old peasant about the best time to mow the grass.
Koznyshev doesn't want to go home yet. He hasn't caught anything, and he wants an intellectual chat.
Levin, in contrast, wants to go home and make plans for mowing and harvesting.
