What two things keep Mr. Raymond from being trash?
Some of the towns people say that Mr. Raymond is not trash because he is white and comes from a land-owning, "good" family.
The things that keeps Dolphus Raymond from being a complete utter trash is that he comes from a wealthy family, which owns a lot of land area near the river source and he is also a white man.
He owns all one side of a riverbank and he's from a very old family. (chapter 16)
