mill, making hackle and gill pins for the weaving industry. This continued until about 1890. The site became Gibraltar Steel Works soon afterwards The water wheel was removed, but the buildings and water from the dam were used in the manufacture of paper bags by A J Allen from before 1923 until his death around 1948. To the East of Grange Lane a mill race fed a dam (the local term for a body of water behind a dam wall) at Grange Mill. Rev J R Eastwood was certain that it was the site of a mill built by the monks of Kirkstead in the 12th century, but it is uncertain on what evidence this was based. There were two mills at the site in the late 17th century, while a lease dating from 1723 mentions the two mills with a kiln and . Grange Mill was destroyed by a fire in 1904 and not rebuilt, although the remains were incorporated into farm buildings. At Blackburn village the brook powered the Blackburn Wheel. There was a small community, with cottages for the workers on the nearby hillside. The wheel contained ten troughs in 1794, and there were 15 men working as fork-makers in 1825. This appears to have been its main use until around 1880, after which it was used to produce foundry blacking from charcoal produced in local woodland. It was then also known as Blacking Mill and labelled as a charcoal works on maps, but the business closed around 1909, and all remains were destroyed by the construction of the Electrode Works. Although the wheel has gone, the former course of the river can be seen by the erratic route that the municipal boundary follows through the site, to the north of the present day Royal Oak public house. Blackburn Brook joins the Don at the site of the former Blackburn Forge, where there were one or two dams fed from the brook. The name of the forge master was Mr Artop or Hartop in 1794, and a tilter called Peter Linley owned it in the 1830s, but little else is known, and it had disappeared by 1892. There was a power station that once stood near the confluence of the Blackburn and the Don called Blackburn Meadows Power Station. The power station was decommissioned in 1980, but both cooling towers could be seen next to the Tinsley
