Here you will find the Poem Negro Speaks of Rivers of poet Langston Hughes
I've known rivers: I've known rivers ancient as the world and older than the flow of human blood in human rivers My soul has grown deep like the rivers. I bathed in the Euphrates when dawns were young I built my hut near the Congo and it lulled me to sleep. I looked upon the Nile and raised the pyramids above it. I heard the singing of the Mississippi when Abe Lincoln went down to New Orleans, and I've seen its muddy bosom turn all golden in the sunset I've known rivers: Ancient, dusky rivers. My soul has grown deep like the rivers.
