Factory windows are always broken.
Somebody’s always throwing bricks,
Somebody’s always heaving cinders,
Playing ugly Yahoo tricks.

In these lines Lindsay sketches a recurring scene of industrial unrest: the factory as a site of perpetual damage and antagonism. The repeated “always” turns broken windows into a symptom rather than an isolated incident—suggesting chronic conflict between industrial order and those who feel excluded, exploited, or simply bored and angry. The diction (“bricks,” “cinders”) evokes the gritty byproducts of industrial life, while “ugly Yahoo tricks” (a Swiftian allusion to the brutish Yahoos of *Gulliver’s Travels*) frames the violence as both dehumanizing and socially corrosive. The stanza reads as a critique of modern industrial society’s capacity to generate resentment, vandalism, and cycles of retaliation.
