I found "The Origin of White Folks" by Annie Virginia Culbertson (it's pretty far down the page) while reading a news article and became intrigued by its accent. The poem is clearly written in some dialect:
DE white folks nee-nter putt on airs
About dem wash'out faces,
De culled folks wuz made de fust,
De oldes' uv de races.
(That's the first four lines; it continues on in a similar fashion) What accent/dialect is this? I don't have the knowledge or skills to identify it. And then, what does it add to the poem? What effect is conveyed by having this specific dialect? There must be some reason to be written like this.
