Hod to page 90

I read to page 90, only 9 more pages!!! Marlow stops Kurtz from being killed or captured by the natives only to have him die slowly on the way back to Europe and be buried in a shallow, muddy grave. Then, Marlow thinks about meanings and kurtz's legacy and other stuff like that. Then some people come to get the papers Kurtz left with him and he was sentimentally stingy with them. He was very annoying towards the end of that section. The most famous line of the book appears in this section: "The horror! The horror!" The meaning of this line is up to interpretation. I personally think that it is referring to the horrors of society back then. But it could also be about the horrors he has seen/ caused or even the horrors to come.
