What happens in chapter 10 ( to killing a mockingbird )

Summary: Chapter 10

"Atticus, Scout says, is somewhat older than most of the other fathers in Maycomb. His relatively advanced age often embarrasses his children—he wears glasses and reads, for instance, instead of hunting and fishing like the other men in town. One day, however, a mad dog appears, wandering down the main street toward the Finches’ house. Calpurnia calls Atticus, who returns home with Heck Tate, the sheriff of Maycomb. Heck brings a rifle and asks Atticus to shoot the animal. To Jem and Scout’s amazement, Atticus does so, hitting the dog with his first shot despite his considerable distance from the dog. Later, Miss Maudie tells Jem and Scout that, as a young man, Atticus was the best shot in the county—“One-shot Finch.” Scout is eager to brag about this, but Jem tells her to keep it a secret, because if Atticus wanted them to know, he would have told them."

Atticus sets some rules with Jem about the use of his new gun. He doesn't wanting him shooting at birds, but he is sure that Jem will. He explicitly tells him never to shoot a mockingbird, since they are the most innocent of the birds.
