Beginning of Heart of Darkness

I have read the first 16 pages of Heart of Darkness and I have taken away one major thing from Conrad's work.  His imagery thus far has been fantastic.  His description of the Thames, Marlow making his way to find the Belgian company and Marlow's first experience climbing the hill and meeting the accountant in the Congo are fantastic.  Conrad's imagery does an exemplary job of implanting the reader into the seen.  He describes every bit of every thing in the scene.  For example, when Marlow first arrives in the Congo, Conrad describes how all the natives looked and delved deeper than their physical appearance to Marlow's observations of how they seemed to feel mentally about thier state.  This writing allows the reader to feel present in the events of the novel and engages the reader making the reader want more.
