style and title of "City" by letters patent in 1893. From the mid-18th century, a succession of public buildings were erected in the town. St Paul's Church, now demolished, was among the first, while the old Town Hall and the present Cutlers' Hall were among the major works of the 19th century. The town's water supply was improved by the Sheffield Waterworks Company, who built reservoirs around the town. Parts of Sheffield were devastated when, following a five-year construction project, the Dale Dyke dam collapsed on Friday 11 March 1864, resulting in the Great Sheffield Flood. Sheffield's transport infrastructure was also improved. In the 18th century turnpike roads were built connecting Sheffield with Barnsley, Buxton, Chesterfield, Glossop, Intake, Penistone, Tickhill, and Worksop. In 1774 a wooden tramway was laid at the Duke of Norfolk's Nunnery Colliery. The tramway was destroyed by rioters, who saw it as part of a plan to raise the price of coal. A replacement tramway that used L-shaped rails was laid by John Curr in 1776 and was one of the earliest cast-iron railways. The Sheffield Canal opened in 1819 allowing the large-scale transport of freight. This was followed by the Sheffield and Rotherham Railway in 1838, the Sheffield, Ashton-under-Lyne and Manchester Railway in 1845, and the Midland Railway in 1870. The Sheffield Tramway was started in 1873 with the construction of a horse tram route from Lady's Bridge to Attercliffe. This route was later extended to Brightside and Tinsley, and further routes were constructed to Hillsborough, Heeley, and Nether Edge. Due to the narrow medieval roads the tramways were initially banned from the town centre. An improvement scheme was passed in 1875; Pinstone Street and Leopold Street were constructed by 1879, and Fargate was widened in the 1880s. The 1875 plan also called for the widening of the High Street; disputes with property owners delayed this until 1895. Steel production in the 19th century involved long working hours, in unpleasant conditions that offered little or no safety protection. Friedrich Engels in his The Condition of the Working Class in England in 1844 described the conditions prevalent in the city at that time: Sheffield became one of the main centres for trade union organisation and agitation in the UK. By the 1860s, the growing conflict between capital and labour provoked the so-called 'Sheffield Outrages', which culminated in a series of explosions and murders carried out by
