How does chesnutt use juxtaposition with the dialects and appearance of mr. ryder's wife, liza jane, and mr. ryder and the other members of the blue veins? how is it (or isn't if you disagree) effective?

Mr. Ryder (along with the rest of the Blue Veins) speaks eloquently and has a polished look. Liza on the other hand speaks in a less eloquent vernacular and has a rougher appearance. Juxtaposing these two characters enhances the effects of the chosen dialects and descriptions of the characters and forces readers to compare the two. Mr. Ryder may speak of values such as fidelity and devotion, but it is Liza who demonstrates these values while Mr. Ryder placed more value on his social standing than his commitment to his wife. The opposition of their values calls for a re-evaluation of societies values.
