How does time in Coketown contrast with the natural time and progression of the entire novel?

Dickens contrasts mechanical or man-made time with natural time, or the passing of the seasons. In both Coketown and the Gradgrind household, time is mechanized—in other words, it is relentless, structured, regular, and monotonous. As the narrator explains, “Time went on in Coketown like its own machine.” The mechanization of time is also embodied in the “deadly statistical clock” in Mr. Gradgrind’s study, which measures the passing of each minute and hour. However, the novel itself is structured through natural time. For instance, the titles of its three books—“Sowing,” “Reaping,” and “Garnering”—allude to agricultural labor and to the processes of planting and harvesting in accordance with the changes of the seasons. Similarly, the narrator notes that the seasons change even in Coketown’s “wilderness of smoke and brick.” These seasonal changes constitute “the only stand that ever was made against its direful uniformity.” By contrasting mechanical time with natural time, Dickens illustrates the great extent to which industrialization has mechanized human existence. While the changing seasons provide variety in terms of scenery and agricultural labor, mechanized time marches forward with incessant regularity.
