Mr. Hale sends Margaret to return Mrs. Thornton's call while Mrs. Hale stays ill at home. Father and daughter walk to Marlborough Street and discover the Thorntons live beside the mill gates, not in the grand house Margaret imagined from Mrs. Thornton's bearing. The yard roars with machinery. Inside, the drawing room is coldly preserved under covers and lace, every ornament polished against smoke, nothing arranged for comfort or daily living. Margaret and her father visit Mrs. Thornton at her home near the factory, where the constant noise and industrial atmosphere shock Margaret.
Mrs. Thornton receives them in black silk, offended that Mrs. Hale did not come in person and suspicious that Margaret might pursue her son. She boasts that John Thornton ranks among Europe's respected manufacturers, then turns to an impending strike. She calls the workers ungrateful hounds who want mastery, not wages, and describes facing a riot herself from the factory roof, ready to drop stones if needed. Margaret listens, pale but steady, and insists she has come to respect John since arriving in Milton. Thornton's values, everything preserved and displayed, but nothing comfortable or welcoming.
That evening John Thornton visits the Hales. Mr. Hale asks about the strike; Thornton says Milton masters will not raise wages and may cut them, and he resents being asked to justify spending his capital like a householder explaining bills to servants. Margaret murmurs that only religious duty could require such stewardship. Their debate widens: he treats workers as children needing firm rule during mill hours and full separation after; she argues that masters and men are bound together and that honest example matters more than lectures. Thornton suspects Margaret might have romantic designs on her son, Margaret's genuine laughter at the idea offends her hostess, revealing how differently they view the world.
Thornton grows heated, then apologizes for speaking roughly and asks forgiveness as an uncouth manufacturer. Margaret smiles, but does not offer her hand. Mrs. Hale's illness still needs a doctor Thornton will recommend, and strike tension rises. Industrial argument has become personal, and neither side yet knows how far it will go. The conversation turns to an impending workers' strike, with Mrs. Thornton declaring the workers 'ungrateful hounds' who want to be masters themselves. When John Thornton arrives later at the Hales' home, he and Margaret clash over labour relations. He argues that masters and workers are like parents and children, workers need firm authority for their own good, while masters have earned the right to make decisions without explanation.
Coming Up in Chapter 16
As tensions in Milton escalate toward the threatened strike, Margaret will witness firsthand the violent realities of industrial conflict that have been simmering beneath their philosophical debates. The opening of CHAPTER XVI. will force Margaret to act faster than she expected, and the choice she makes there will echo through every relationship still ahead..
