The Adventures of Tom Sawyer
How we cite our quotes:
"Did you think I'd forget? The Injun blood ain't in me for nothing. And now I've got you, and you got to settle, you know!" (9.48)
Injun Joe seems to use stereotypes about his race as a justification for his actions; they offer an excuse for his rage.
"O, lordy, I'm thankful!" whispered Tom. "I know his voice. It's Bull Harbison."
(Note: If Mr. Harbison had owned a slave named Bull, Tom would have spoken of him as "Harbison's Bull," but a son or a dog of that name was "Bull Harbison.") (10.42-43)
Here, something as simple as a naming system emphasizes how demeaning slavery is; slaves, we are told, are referred to like possessions, while dogs are named like sons.
The first of all the negro minstrel shows came to town, and made a sensation. Tom and Joe Harper got up a band of performers and were happy for two days. (22.4)
Tom and Joe live at a time when African Americans were not only forced into slavery, but were demeaned for the purposes of entertainment.
