"Sarah developed Realism in "A White Heron" by giving so much detail in her story. Her story also has a lot of local colors which helps, as well as Regionalism. She details physical landscape a lot, giving the audience a feeling of being there with the character, like they are really there, and like everything is REAL. As for Bret Harte, he developed realism in Tennessee's partner by also showing lots of realism, but also because she showed how crude the men w, and how they acted and how they talked, and that helped to show the reader what it was like where they lived back then. That shows Realism. Because he showed the main characters in their real, raw, true selves, along with how they talk, act, and how they see everything."
