at right angles to the modern weir. The leat curved round to the east, and there was a second weir, parallel to the modern river bank, below Gooseholme foot bridge. The mill was to the south of Bridge Street, and a long tail race rejoined the river below Parr Street. It was built in 1805–06, just to the north of a corn mill and fulling mill, by William Braithwaite and Isaac Wilson. From 1840 it was owned by J J and W Wilson, who introduced steam power in 1850. The mill manufactured travelling rugs, blankers, tweeds, linings and collar checks. It was extended in 1855 when a new water wheel and a beam engine were installed, each rated at , while further expansion took place in 1872. It employed some 500 people, with water turbines providing power from 1899, but in 1933 the company failed, and was bought by Goodacres, who manufactured carpets there. The site ceased to use water power in 1940. Somewhere below the Castle Mills site was Kirkbarrow Spinning Mill, which was described as the first in the district in 1798. Low Mills were fred from a weir located where the modern Romney Bridge has been built. The leat ran alongside Natland Road, on the east bank, and the mill buildings were just to the north-east of the sewage treatment works. The mill was quite extensive, as in 1805 it was advertised as having three water wheels, six subsidiary mills, two fulling stocks, one carding engine, and eight friezing engines. John and Thomas Ireland bought the mill and used it to produce horse clothing and collar checks, while by 1848, parts of it were in use by Caleb Metcalf & Sons for producing woollens. Disaster struck in 1891, when it burnt down, but Richardson & Co rebuilt it, and it produced woollens from 1900 until it closed in 1924. Snuff and gunpowder mills Immediately after the long loop of the river that enclosed the Concangium Roman station, a long weir fed a leat to the west of the river, which fed mills at Helsington Laithes. A local architect called Francis Webster rented the site from the Lord of the Manor in about 1800, and built a weir and two water mills. It was known as a marble works, but the largest mill was used to polish local limestone for ornamental use, and the smaller mill was a
