The ostentatious behaviour and conversation of the others at the party repulse Nick, and he tries to leave. At the same time, he finds himself fascinated by the lurid spectacle of the group. Myrtle grows louder and more obnoxious the more she drinks, and shortly after Tom gives her a new puppy as a gift, she begins to talk about Daisy. Tom sternly warns her never to mention his wife. Myrtle angrily says that she will talk about whatever she chooses and begins chanting Daisy’s name. Tom responds by breaking her nose, bringing the party to an abrupt halt. Nick leaves, drunkenly, with Mr McKee, and ends up taking the 4 a.m. train back to Long Island.
Unlike the other settings in the book, the valley of ashes is a picture of absolute desolation and poverty. It lacks a glamorous surface and lays fallow and grey halfway between West Egg and New York. The valley of ashes symbolizes the moral decay hidden by the beautiful facades of the Eggs, and suggests that beneath the ornamentation of West Egg and the mannered charm of East Egg lies the same ugliness as in the valley. The valley is created by industrial dumping and is therefore a by-product of capitalism. It is the home to the only poor characters in the novel.
The undefined significance of Doctor TJ Eckleburg’s monstrous, bespectacled eyes gazing down from their billboard makes them troubling to the reader: in this chapter, Fitzgerald preserves their mystery, giving them no fixed symbolic value. Enigmatically, the eyes simply “brood on over the solemn dumping ground.” Perhaps the most persuasive reading of the eyes at this point in the novel is that they represent the eyes of God, staring down at the moral decay of the 1920s. The faded paint of the eyes can be seen as symbolizing the extent to which humanity has lost its connection to God. This reading, however, is merely suggested by the arrangement of the novel’s symbols; Nick does not directly explain the symbol in this way, leaving the reader to interpret it.
The fourth and final setting of the novel, New York City, is in every way the opposite of the valley of ashes—it is loud, garish, abundant, and glittering. To Nick, New York is simultaneously fascinating and repulsive, thrillingly fast-paced and dazzling to look at but lacking a moral centre. While Tom is forced to keep his affair with Myrtle relatively discreet in the valley of the ashes, in New York he can appear with her in public, even among his acquaintances, without causing a scandal. Even Nick, despite being Daisy’s cousin, seems not to mind that Tom parades his infidelity in public.
The sequence of events leading up to and occurring at the party defines and contrasts the various characters in The Great Gatsby. Nick’s reserved nature and indecisiveness show in the fact that though he feels morally repelled by the vulgarity and tastelessness of the party, he is too fascinated by it to leave. This contradiction suggests the ambivalence that he feels toward the Buchanans, Gatsby, and the East Coast in general. The party also underscores Tom’s hypocrisy and lack of restraint: he feels no guilt for betraying Daisy with Myrtle, but he feels compelled to keep Myrtle in her place. Tom emerges in this section as a boorish bully who uses his social status and physical strength to dominate those around him—he subtly taunts Wilson while having an affair with his wife, experiences no guilt for his immoral behaviour, and does not hesitate to lash out violently in order to preserve his authority over Myrtle. Wilson stands in stark contrast, a handsome and morally upright man who lacks money, privilege, and vitality.
Fitzgerald also uses the party scene to continue building an aura of mystery and excitement around Gatsby, who has yet to make a full appearance in the novel. Here, Gatsby emerges as a mysterious subject of gossip. He is extremely well known, but no one seems to have any verifiable information about him. The ridiculous rumour Catherine spreads shows the extent of the public’s curiosity about him, rendering him more intriguing to both the other characters in the novel and the reader.
