Little Women Chapter 10
Spring has come, and each girl has a part of the garden that they plant themselves in accordance with their varying tastes. Their secret society, The Pickwick Club, puts out a weekly newspaper. They each publish in it under a pen name. In the newspaper they publish their poetry, stories, fables, letters, death notices of beloved pets, advertisements, and a weekly report on each sister's behavior.
At one meeting of the Pickwick Club, Jo sneaks Laurie in. The girls object to him joining at first, but they agree to it when they find out that Laurie has set up a mailbox between their yards in which they can leave messages to each other.
