Themes & patterns

The novel centers on the wheat trading pit of the Chicago Board of Trade, exploring how speculation, greed, and the pursuit of wealth consume characters like Curtis Jadwin and lead to ruin, as seen in the 'Unknown Bull's' corner and the downfall of Charles Cressler.

The relationship between Laura Dearborn and Curtis Jadwin is a central thread, showing how love and marriage are tested by Jadwin's obsessive involvement in the wheat market, ultimately leading to a reconciliation that prioritizes their bond over material wealth.

The wheat itself is portrayed as a vast, indifferent natural force—the 'Nourisher of the Nations'—that overwhelms human attempts to control it, as when Jadwin reflects that 'the wheat cornered itself,' highlighting the futility of human ambition against elemental cycles.

Laura Dearborn's move from provincial Barrington, Massachusetts, to Chicago represents a struggle with social expectations and personal ambition, as she rejects narrow New England conventions and seeks a broader life, while characters like Landry Court and the Gretry family navigate class distinctions.

The pursuit of fortune in the wheat pit embodies the American Dream, but the novel shows its devastating costs: financial ruin, suicide (Cressler), and the erosion of personal relationships, as seen in the cascade of failures after Jadwin's corner collapses.

Laura Dearborn's character challenges traditional gender roles through her intellectual ambitions, desire for an acting career, and her eventual role as a moral anchor in her marriage, while Page's more conventional path highlights the limited options for women in the era.

The contrast between Laura's restrictive upbringing in rural Barrington and the dynamic, often ruthless energy of Chicago underscores the tension between small-town values and the impersonal forces of the modern city, where the wheat pit becomes a symbol of urban capitalism.

Characters struggle against forces beyond their control, such as market fluctuations and natural crop yields, yet their choices—like Jadwin's decision to mortgage everything—drive the plot, raising questions about whether destiny or human agency determines outcomes.
