How does the differing contribution of each girl to the Pickwick Chronicles show her character?

Check this out. It will give you a sense of personality that each girl contributed to the paper,

During the meetings of the P.C., each of the girls impersonates one of the characters in The Pickwick Papers. Meg is Samuel Pickwick, Jo is Augustus Snodgrass, Beth is Tracy Tupman, and Amy is Nathaniel Winkle.

The P.C. produces a newsletter that they call The Pickwick Portfolio, in which each of the girls contributes articles. This is appropriate, since The Pickwick Papers is also about, well, papers. The clue's in the name!

At their meetings, Meg, as Mr. Pickwick, reads the paper they've produced this time to her sisters.

The edition of The Pickwick Portfolio that Meg reads in this chapter contains the following articles:

A poem celebrating the anniversary of the club, written by Jo.

A romantic tale about mistaken identity and marriage in Venice, written by Meg.

A joke about the club.

A recipe for baked squash, written by Beth.

A letter explaining why she hasn't written anything for the newsletter, by Amy.

A report of an accident that Meg had while getting firewood in the attic.

A description of the family's missing cat, Snowball.

A poem lamenting the lost cat, written by Jo.

A variety of announcements about things that are going to happen soon, such as Hannah teaching the girls to cook and Beth displaying the new doll's clothes she has made.

A comment on the behavior of each of the girls.

Meg, in the character of Samuel Pickwick, finishes reading each of these items from the paper and the girls applaud.
