What does the Negro sell to the Grade School Chum?

In the poem "The Negro Speaks of Rivers" by Langston Hughes, the phrase "the Negro sells to the Grade School Chum" reflects the idea of cultural exchange and the sharing of heritage. The "Negro" symbolizes the African American experience, and what is offered can be interpreted as wisdom, resilience, and a rich history. This interaction highlights the importance of recognizing and valuing the contributions of African Americans to society, especially in educational settings. The imagery suggests a deeper connection between generations and cultures.
