Kinahan — On Irish Metal Mining. 281 



in part used ; but it was mixed with clay-iron-stone from counties 

 Limerick and Clare, and limonite from Tomgraney, Co. Clare, 

 brought up the Shannon in boats ; the furnace and mills being 

 erected hereabouts, on account of the vast forests in the neighbour- 

 ing hills. 



There were also furnaces in places on the western coast : to 

 these foreign ore was brought by sea, to be mixed with the native 

 bog-iron-ore. 



The native sulphur found in the limestone at Oughterard 

 seems to be long known, as the ancient name of the river is 

 Owenriff, anglice Brimstone River. Blue fluor spar occurs at Ju- 

 verin, west of Spiddal, while pale-bluish, greenish,, and yellowish 

 translucent varieties were found at Grlengowla, Dear Oughterard. 



Kerry, 



In the south- west of the county, including the promontory of 

 Ieveragh and the Killarney hill?, are Devonians and Silurians 

 •similar to those of West Cork (see page 273), having on them, 

 alongside the bay called Kenmare River, Yellow Sandstone and 

 Carboniferous Slate ; but eastward, at Kenmare, these are replaced 

 by cleaved Limestone and Lower Limestone Shale, or the transition 

 rocks between those of the West Cork types and those of the 

 ^Central plain types {West Cork roclc, p. 273). 



In the Dingle promontory there are Silurians and Ordovicians. 

 To the northward and eastward (Slieve Mish) these are capped 

 unconformably by rocks that represent the upper portions of the 

 Devonian rocks of West Cork; while further northward in the 

 Kerry Head promontory are similar rocks. The Kerry Head 

 and Slieve Mish Devonians lie conformable under the Carboniferous 

 Sandstone Shales and Limestones of the low country to the eastward, 

 the latter being capped by Coal Measures, a part of the extensive 

 West Munster Coal-field. 



As has been mentioned, in the resumi OB Cork, the coals 

 known in the Kerry portion of this field are of little value, while 

 there are small prospects of better being found. In general these 

 are more or. less culm, or thin. Not much clay-iron-stone is 

 recorded ; some, however, was raised in old times.
