Plot Summary
This section opens Part II of Heart of Darkness with Marlow overhearing a private conversation between the Manager and his uncle, the leader of the Eldorado Exploring Expedition. Lying on the deck of his steamboat, Marlow learns crucial details about Kurtz: that he was sent to the Inner Station with the idea of demonstrating his abilities, that he has amassed remarkable quantities of ivory, and that he mysteriously turned back into the wilderness after traveling three hundred miles toward civilization. The Manager and his uncle express jealousy and resentment toward Kurtz, hoping that the hostile climate will eliminate him as a rival. The uncle gestures toward the surrounding jungle, invoking its lethal power as their ally.
The Eldorado Expedition departs into the wilderness and is never heard from again. Marlow then describes the two-month journey upriver toward Kurtz's station. The voyage becomes an increasingly surreal passage through primeval landscape—dense forests, silvery sandbanks with hippos and alligators, and the oppressive silence of an ancient world. The steamboat crew includes cannibals enlisted along the way, and the pilgrims aboard carry their iconic staves. As they penetrate deeper into the continent, they encounter isolated trading stations and hear mysterious drumbeats at night.
Character Development
Kurtz emerges more vividly in this section, though still only through others’ words. Marlow learns that Kurtz espouses idealistic rhetoric about stations being “beacons on the road towards better things” and centers for “humanizing, improving, instructing.” This idealism contrasts sharply with the Manager’s purely mercenary outlook. The Manager reveals himself as petty and scheming, relying on the climate to eliminate rivals rather than confronting them directly. His uncle serves as a cynical co-conspirator. Marlow’s fascination with Kurtz deepens; he begins to see Kurtz as someone who “stuck to his work for its own sake,” a romantic figure who chose the wilderness over civilization.
Themes and Motifs
The journey upriver becomes Conrad’s central metaphor for regression into humanity’s primitive origins. Marlow describes traveling “back to the earliest beginnings of the world” and feeling like a wanderer “on a prehistoric earth.” The title phrase appears explicitly: “We penetrated deeper and deeper into the heart of darkness.” The motif of silence dominates, representing both the indifference of nature and the unknowable interior of the African continent. Ivory continues to function as a symbol of colonial greed, the one word that “would ring in the air” at every station. The opposition between surface reality and hidden truth emerges as Marlow notes that attending to practical tasks causes deeper reality to fade.
Literary Devices
Conrad employs dramatic irony through the overheard conversation, allowing readers to grasp the Manager’s scheming while he remains unaware of Marlow’s presence. The uncle’s gesture toward the wilderness is richly symbolic—a “dishonouring flourish” that invokes “lurking death” and “hidden evil.” Extended similes compare the steamboat to a “sluggish beetle crawling on the floor of a lofty portico” and the journey to a blindfolded man driving a van. The frame narrative resurfaces briefly when a listener interrupts Marlow, reminding readers of the storytelling context aboard the Nellie. Conrad’s prose rhythm mirrors the river’s flow, with long, accumulating clauses that create a hypnotic, dreamlike effect.
