what is the type of atmosphere is creatid in part one ?

Conrad creates an atmosphere that is ominous and foreboding. Marlow states "And this also has been one of the dark places of the earth" in the very first introduction we have to his narration. As he recounts his experiences at the Company Office, we see the irrationality and disorganization that is prevelant within the companu leading us to distrust the company that is sending Marlow into the "darkness"--the Congo.
