Chapter 29 of To Kill a Mockingbird finds Atticus Finch talking with the sheriff, Heck Tate and only after a while does Scout notice Boo Radley in the corner, literally apart from society as he has been figuratively for so long.
As Sheriff Tate talks with Atticus much of the colorful colloquialisms of his region are evident. For instance, when Aunt Alexandra says that she has had a premonition about the occurrences of this evening, Heck Tate tells her not to "fret about anything," using the simile,
"...if we followed our feelings all the time we'd be like cats chasin' their tails." [comparison of people with cats using the word like]
Another simile occurs in Chapter 30 when Scout narrates,
....Atticus's stubbornness was quiet and rarely evident, but in some ways he was as set as the Cunninghams,....[comparison using as]
There also are several metaphors among the stylistic devices that Harper Lee employs.
For instance, Scout says that she "buried my head in his lap," comparing her movement of placing her head on Atticus's lap as an act of burying. A couple of sentences later, she narrates that she "crawled into his lap."
Another metaphor comes from Chapter 29 as Scout describes Cecil Jacobs, whom she mistook Bob Ewell for, as "a big, fat hen."
Scout's description of Boo Radley is hyperbolic (obviously exaggerated):
They were white hands, sickly white hands that had never seen the sun, so white they stood out garishly against the dull cream wall in the dim light of Jem's room.
Harper Lee also uses imagery with her description of the view of the neighborhood from Boo Radley's porch. Scout describes the "brown door," "daylight," the "fuzzy" street lights, "the fine misty beads" of the night air.
personification "the same shy smile crept across his face." 30
"He was out of his mind." Atticus uses an idiom.
