What literary elements are found in chapters 29-31 of "To Kill a Mockingbird"?I only need one or two elements.

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):

readability="8">

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.
