The "Part First" of this novel is called "The Silver of The Mine." Holy Yoda-style diction, Batman. Why can't it be called First Part: The Mine's Silver? You'll have to ask Joe Conrad.
This chapter is pretty action-free (and proud). It gives us a detailed description of the physical landscape in Sulaco, a fictional Latin American port/province (which located in the fictional Republic of Costaguana).
Also, we hear the story of three dudes who went looking for treasure and got in trouble as a result: symbolically important anecdote alert!
