In Chapter 19 - "The Child at the Brook-side," much of the chapter which I am not including contains images of nature that mirror Pearl's personality and mood. This forest is home to her as it is home to Indians. When her anger is aroused because Hester has thrown away the A and freed her hair, Pearl's behavior is like the stereotyped behavior and shrieks of a wild Indian.
But Pearl, not a whit startled at her mother's threats, any more than mollified by her entreaties, now suddenly burst into a fit of passion, gesticulating violently, and throwing her small figure into the most extravagant contortions. She accompanied this wild outbreak with piercing shrieks, which the woods reverberated on all sides; so that, alone as she was in her childish and unreasonable wrath, it seemed as if a hidden multitude were lending her their sympathy and encouragement. Seen in the brook, once more, was the shadowy wrath of Pearl's image, crowned and girdled with flowers, but stamping its foot, wildly gesticulating, and, in the midst of all, still pointing its small forefinger at Hester's bosom!
