I think that Langston Hughes’s “The Negro Speaks of Rivers” was better at reaching a wider audience than Countee Cullen’s “Yet do I Marvel” because of the language, structure, and tone of the poem.  Also people know more about the events that Hughes was alluding to in his poem which leads to an easier understanding of the theme of the poem.  Hughes was able to fit in a lot of figurative language while at the same time letting the audience really feel the way he is feeling towards the theme.  The fact that the poem was free verse lets a wider audience appreciate what he was trying to say between all the allusions and metaphors.
