⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

Amos Barrowfield rises at four and walks through a depressed Kingsbridge. War has stifled trade and he has no new orders. At the mill, he promotes fourteen-year-old Kit to tackler—a full-time maintenance man—paying him five shillings a week, a gesture that delights Kit’s mother, Sal Box. Meanwhile, Hornbeam proudly shows his son Howard the first steam-driven mill in Kingsbridge, a building larger than the cathedral. The new engine will allow one man to supervise four looms, reducing the workforce to a quarter. At the May Fair, Amos meets Jane Northwood, who confesses her unhappy marriage: she rarely sees Henry, lives in dull Earlscastle, and openly says she may have an affair. When she kisses Amos in the woods, he resists out of guilt. Later, Sal and Jarge investigate Hornbeam’s mill and discover the power looms. Alarmed, they consult Spade, who advises forming a union and, if necessary, striking. Meanwhile, Spade’s secret lover, Arabella, reveals she is pregnant. In a tense meeting at the Guild Hall, Sal confronts Hornbeam, who refuses to compromise. Sal walks out, and the weavers prepare to strike.

Character Development

Amos Barrowfield – Demonstrates his ethical Methodism by resisting Jane’s advances, but also shows business pragmatism: he promotes Kit because it increases efficiency, and he respects Sal’s advice. His moral compass remains strong even when tempted.
Hornbeam – Becomes more entrenched and arrogant. He dismisses workers’ health and refuses to listen to reason, revealing a deep stubbornness driven by pride in his new machine. His wealth and power have isolated him from empathy.
Sal Box – Grows into a natural leader. She overcomes her nervousness at the Guild Hall, uses Spade’s advice to reframe the conflict, and speaks with unexpected authority. Her decision to strike marks her transformation from a hand to an organizer.
Spade – Acts as a strategist and mentor, but his personal life is humanized by his genuine joy at Arabella’s pregnancy. His quiet happiness contrasts with the public conflict.
Jane (Viscountess Northwood) – Reveals the emptiness of her social-climbing marriage. She is isolated and unhappy, willing to risk an affair for affection, but Amos’s rejection deepens her frustration.
Kit – Shows mechanical curiosity and bravery. He is not afraid of the machines, unlike the adults, and his scientific mindset points to the future.

Themes, Symbols, and Motifs

Steam and industrial change – The steam engine symbolizes unstoppable progress that threatens traditional craft. Hornbeam’s mill is built on a piggery, suggesting that the new order rises from filth and waste.
Class conflict and unionization – The chapter directly depicts the birth of the weavers’ union. Spade’s advice—to organize, collect funds, and strike—reflects real historical methods. The meeting at the Guild Hall highlights the power imbalance.
Moral boundaries and temptation – Amos’s refusal of Jane shows the conflict between desire and duty. His Methodism gives him a clear ethical line, but he pays the price in loneliness.
Secrecy and intimacy – Spade and Arabella’s hidden relationship mirrors the secretive nature of the union preparations. Both require discretion to avoid ruin.
The cost of war – The war with France is the backdrop for poverty and the demand for uniforms. Hornbeam profits from it while Amos cannot get orders; the hands bear the suffering.

Why This Chapter Matters

This chapter is a turning point in the novel’s social plot. The introduction of steam power makes the conflict between capital and labor explicit. Sal’s decision to strike and Hornbeam’s refusal to negotiate set the stage for a showdown that will likely escalate into violence. Meanwhile, Amos’s personal discipline and Jane’s unhappiness deepen the emotional stakes. The secret pregnancy of Arabella creates a new tension that will complicate Spade’s involvement in the strike. The chapter balances industrial revolution, personal morality, and class struggle, pushing every major storyline toward crisis.

Study Questions and Answers

How does Amos’s treatment of Kit reflect his business philosophy?
Amos believes in rewarding extra effort and efficiency. By making Kit the tackler, he increases production and saves money on repairs. It also shows his willingness to listen to workers, as Sal suggested he get military orders. This contrasts with Hornbeam, who sees workers only as costs.
Why does Jane reject the values her father, Charles Midwinter, taught her?
Jane abandoned her father’s Methodist humility to pursue social status. She married Henry for rank and money, but now finds herself lonely and unloved. Her desire for an affair and her attraction to Amos reveal that she yearns for emotional authenticity, but her choice of marriage has trapped her.
What strategic advice does Spade give Sal about confronting Hornbeam?
Spade tells Sal to treat Hornbeam as someone with a shared problem rather than an enemy. He advises her to speak for herself, not let him represent her, and to keep the initiative. This approach works at first, but when Hornbeam refuses to compromise, Sal knows a strike is inevitable.
