Boate states that the large furnaces and works, except those on 

 the coast-line, were each built convenient to a mine ; while the 

 bloomeries were moved from place to place, where the fuel was 

 most abundant. We may therefore suppose that formerly 

 iron-mines existed close to most of the above-mentioned 

 furnaces. 



The majority of these iron- works were destroyed in 1641, 

 during the troubled times ; but many of them were afterwards 

 reinstated, while other works and mines were also started. 



Later in Wicklow an Englishman of the name of Bacon erected 

 works at Shillalagh, and introduced the importation of pig-iron 

 from Wales. These works were carried on by his son-in-law 

 Cholmondeley, who changed his name to Chamney, and the latter, 

 or his descendants, are said at one time to have had fifty-two 

 works, between founderies, mills, furnaces, and bloomeries, in the 

 counties Wicklow, Wexford, and Carlow ; the Chamneys, besides 

 importing ore, worked mines in different places. In Cork, at 

 Coomhola and Roaring Water, were the mines of the Whites. 

 In Clare and Q-alway, the Bradys of Raheen, the Burkes of 

 Marble Hill, and others, opened new mines and established 

 works ; while in Mayo, the Gildeas of Port Royal were large 

 Iron-masters. There were also elsewhere mines and works, that 

 sprung up, to die out subsequently, as the forests were gradually 

 exhausted. At the present time the Bog-iron-ore is exported from 

 Donegal, Londonderry, and elsewhere, to be used in the puri- 

 fication of gas. The raw product, in itself, is of little value ; 

 but after it has taken up the gas impurities the " Gas Wastes," 

 as it is called, is so valuable that the exporters find it profit- 

 able to supply, free of cost, the Gas, on the condition that 

 they are returned all the " Gas Wastes." The latter are used 

 for the manufacture of very pure sulphuric acid and brown 

 paint.
