Reading Difficulties Pages 102-118

"In a few days the Eldorado Expedition went into the patient wilderness, that closed upon it as the sea closes over a diver. Long afterwards the news came that all the donkeys were dead. I know nothing as to the fate of the less valuable animals. They, no doubt, like the rest of us, found what they deserved. I did not inquire. I was then rather excited at the prospect of meeting Kurtz very soon. When I say very soon I mean it comparatively. It was just two months from the day we left the creek when we came to the bank below Kurtz's station"(Page 105, 3rd paragraph). In this section the narrator talks about the fact that the donkeys of the Eldorado Expedition all died. This part confused me because it jumps around a lot and it was unclear to me why this particular section is significant? Also when the narrator says the part "They, no doubt, like the rest of us, found what they deserved", he is seemingly referring to the Donkeys, but the language of "they found what they deserved" is difficult to decipher. This section could mean many different things and while the language itself was not difficult to understand the meaning of the section as a whole was.
