In the book Uncle Tom's Cabin find an example of sarcasm in this chapter when Stowe is criticizing the lawmakers for permitting slave trading inside the county,even after it has long been outlawed to import slaves from Africa.

I find Stow using this excerpt that is filled with sarcasm. Here, Mr. Haley thinks he is a swell guy for how he treats Tom:

"...and how humane he was, that whereas other men chained their "niggers" hand and foot both, he only put fetters on the feet, and left Tom the use of his hands, as long as he behaved well; and he sighed to think how ungrateful human nature was, so that there was even room to doubt whether Tom appreciated his mercies. He had been taken in so by "niggers" whom he had favored; but still he was astonished to consider how good-natured he yet remained!" (Chapter 12)
