A HISTORY OF DURHAM 



Tow Law, a position convenient for both iron 

 ore and coal. In 1853 forges, and in 1870 blast 

 furnaces, were also erected at Tudhoe, and these 

 are still smelting the only ironstone ^^ mined in 

 the county of Durham, namely from the Carrick 

 Ironstone Mines and the Rookhope Iron Mines, 

 both in Weardale. The production is, however, 

 very small, so that even the well-known ' Tud- 

 hoe and Weardale ' brand of pig-iron of the 

 Weardale Iron Company is made from a mixture 

 of Weardale and Cleveland ironstone. The 

 present company, known as the Weardale Steel, 

 Coal and Coke Company Limited, has joined 

 forces with two other large companies, the South 

 Durham Steel and Iron Company Limited and 

 the Cargo Fleet Iron Company Limited, the latter 

 owning extensive ironstone mines at Cleveland, 



" In 190;, 9,579 tons of brown iron ore were 

 mined at Carrick, or Craig's Level, and 3,114 tons 

 obtained from quarries or open-cast workings. The 

 average production of iron may be reckoned at about 

 30 per cent, of this ; Mines and Quarries Gen. Rep.

and here again the business of iron-smelting has 

 advanced by leaps and bounds, whilst that of 

 iron-mining has shrunk to very small dimensions. 



BARYTES 



Durham is one of the few English counties 

 from which sulphate of baryta is obtained in any 

 quantity, the output in 1905 reaching a total ot 

 some 5,626 tons, of which 1,507 came from the 

 Cow Green Mine, 85 from the Flush O'Mea, 

 and 4,034 from a very curious fault-fissure in 

 the New Brancepeth Collieries. The estimated 

 value of the mineral raised was ^^2,630.' 



FLUORSPAR 



A considerable amount of fluorspar is obtained 

 from Weardale, the chief producers being Sed- 

 ling and Stanhopeburn mines, and the output 

 about 10,000 tons per annum.
