"a long report from the steelworks in Sheffield"

 In the 1800s, Sheffield in South Yorkshire developed an international reputation as a centre of the steel industry. Many technologies, such as stainless steel, were developed in Sheffield, which grew from a population of 60,000 to 451,000 over the century. The city is mentioned in Friedrich Engels' The Condition of the Working Class in England in 1844, where he examines the working conditions in the factories. The city continued as an industrial centre until the 1970s, when much of the industrial economy of England collapsed.
