The industrial revolution • 287 • during the eighteenth and nineteenth centuries. Copper, tin and lead had been worked on a small scale for centuries, but new demands were created by, for example, ship building, tin plating or the metal trades of Birmingham or the need for engines. In the Derbyshire Pennines, for example, lead occurs as veins in the limestone, and early mining can be traced where it follows the ore in long rakes that criss-cross the landscape; at Charterhouse in Somerset, continuity in mining is suggested from the Roman period until the nineteenth century. In order to process lead ore, it has first to be crushed and then washed, and associated with such rakes are often found remains of stamp mills and Figure 16.4 Landscape at Parys Mountain, Anglesey, showing the legacy of copper working. Source: Kate Clark buddles, used to wash the ore, such as the complex excavated at Killhope, Co. Durham (Cranstone 1989). Copper mining on a large scale began in 1568, and continued until largely superseded by imported ores at the end of the nineteenth century. Copper occurred in workable quantities in Cornwall, Devon, Anglesey and the Lake District, and perhaps one of the best surviving landscapes is at Red Dell Beck in the Lake District, where crushing and stamping works, adits, shafts and waste heaps survive. The spectacular landscape of Parys Mountain, Anglesey, is all that remains of what was once the largest copper working in Europe, where working continued until 1815, with a few subsequent revivals (Figure 16.4). The nearby harbour at Amlwch developed in the eighteenth century as a port for shipping the copper ore out to smelters sited closer to sources of coal. Such sites also demonstrate the general principle that the final smelting of minerals such as iron, lead or copper rarely took place in areas where they were mined. Field evidence suggests that fuel, or easy access to fuel via a good transport network, was a more important determinant of location. Relatively little copper smelting took place in Cornwall; most of it occurred in areas such as Swansea in south Wales, where there were plentiful supplies of cheap coal. At Gawton in West Devon, archaeological survey of a quay, copper mine, lime kilns and arsenic works show how copper mining operated together with a variety of other activities at a site that had the advantages of both raw materials and transport. Another complex associated with copper mining is Aberdulais Falls in West Glamorgan, where ironworking and tinplate manufacturing were also found. Such sites are very common and illustrate how difficult it is archaeologically to isolate the evidence for single industries from their contexts. Power systems The processing of minerals in any quantity depended upon a ready supply of power, as indeed did the functioning of many other industries. The move from water power to steam power is one of the factors commonly cited as being responsible for the large increases in output in British manufacturing in the latter part of the eighteenth century. Archaeological evidence,

• 288 • Kate Clark nevertheless, suggests that water power remained important for industrial purposes until well into the nineteenth century, and well after the steam engine had become firmly established (Cossons 1987). Waterwheels were cheap, easy to install, and could drive rotative machinery well before steam engines could; only after the 1840s were steam engines built that were more powerful. The technology of the waterwheel was well established by the sixteenth century, and by the early eighteenth century simple undershot wheels were common. Key technical developments in waterwheel technology through the eighteenth and early nineteenth century include improvements to the buckets, and more elaborate means of driving wheels to take advantage of different conditions. The water turbine was developed after 1820 by Benoit Fourneyron in France to take advantage of low heads of water, and the technology spread, perhaps illicitly, to Northern Ireland where they were manufactured by the MacAdam brothers of Belfast in the 1840s. Water turbines remain in use today for the generation of hydro-electricity. Many waterwheels survive in Britain, and at many sites field survey of the associated leats, sluices and tailraces, and analysis of the relevant falls is often the only source of evidence for the precise way in which the system worked. At Quarry Bank Mill, Styal in Cheshire, more explicitly archaeological techniques have been used to untangle the sequence of use of water, steam and gas as sources of power at a large textile mill complex. Although a steam engine was installed at the site in 1810, waterwheels remained in use there until 1889 when water turbines were installed, demonstrating that various sources of power often coexisted (Milln 1995). Archaeological analysis has also been used at Bordesley, Worcestershire, where remains of a water-powered needle mill were identified. Through time, many industrialized valleys developed extremely complex water power systems, often with steam engines being used not to drive the machinery directly (although such technology was available) but to pump water back up, so it could be recycled back around the earlier dams and waterwheels. Indeed, Cossons (1987) argues that the decline in water power may have had more to do with the diversion of water by land drainage schemes, or for urban domestic consumption, than the inefficiency of water power itself. Whilst water power remained common in rural areas until the nineteenth century, and indeed survived in some places until the twentieth century, in urban areas the take-up of steam was more widespread. This illustrates the ultimate advantage that steam had over water power—it was a flexible, movable source of power that could be set up where required. Despite the importance of water power (and its greater legibility in the archaeological record), the application of steam engines to industrial uses from mining, and mineral production, through to textiles, manufacturing and transport, undoubtedly made possible much higher levels of productivity, and ultimately freed many areas of manufacturing from dependency upon human and horse power. Newcomen engines remained in use for pumping coal mines where fuel was relatively cheap and where vertical motion was the main requirement. However, the improvements in steam engines created by Watt’s patents of the late eighteenth century resulted in engines that used less fuel and thus were cheaper, and could turn as well as lift. Textile mills, forges, metal works, glass making, breweries and water works all found ready uses for such engines, and by 1800 nearly 500 had been built. Steam engine development did not stop with Boulton and Watt, and throughout the nineteenth century a series of patents resulted in smaller, more powerful and yet more portable engines. Reciprocating steam engines were used for electricity production in the 1880s, but only began to become redundant with the patenting of the steam turbine in 1884, which was immediately useful for electricity generation. The portability of steam engines is illustrated by the earliest surviving engine, a Newcomen engine that today stands in Dartmouth.
