Kinahan — On Irish Arenaceous Rocks. 595 



stone ; in the latter are some hastily selected, which have stood 

 badly. At Clonaslee and Rosenallis there is a thin-bedded stone, 

 very extensively used in the county for flagging ; they cannot be 

 obtained of large sizes, but are very dry ; when first raised they 

 are soft, but rapidly harden. Stones for cut work can also be 

 procured ; but, on account of the ungainly shapes of the blocks, 

 are expensive to dress. 



Clara Hill, Clonaslee. — Yellowish ; very silicious ; fine-grained ; 

 micaceous ; ferriferous spots. 



Tinahinch. Three miles from Clonaslee. — Greenish-white ; 

 silicious-grained ; argillaceous cement ; partially carbonaceous 

 matter. 



Olenbarroiv. Three miles from Clonaslee.— Grey ; silicious- 

 grained ; ferriferous spots. 



Rosenallis Mountain. — Westward of Mountmellick. Very 

 similar to the Clara Hill stone. 



Ballysally. Ten miles from Eoscrea, where it has been much 

 used. — Yellowish to lightish-brown. Is soft when raised, but 

 hardens on exposure. Works easily. 



Coal-measures. — In general, these stones are not now looked 

 after, yet that they are capable of good work can be seen in the 

 previously-mentioned doorway of Killeshin Church, Co. Carlow 

 (page 537). In some of the ancient buildings a thin-bedded grit 

 has been used, also in latter years at Cloggrennan. As those 

 used at Cloggrennan were not suited for cut-stone purposes, other 

 material was used for the dressings. 



Cloggrennan. — Dark-greenish grey ; fine-grained; close; dense; 

 flaggy ; not good for cut work. 



Corgee and Hollypark. In the Collieries. — Good strong flags 

 were formerly rather largely worked. These flags, on an average, 

 could be raised 12 feet square, the largest raised being 22 feet 

 long and 12 feet wide (G. 8. M.) 



Berry/ore. East of Abbeyleix. — Olive, thick sandstones and 

 flags. 



Sand and Gravel. — Both of excellent quality occur plenti- 

 fully in the Eskers. In some of the streams coming down from 

 both the Lower Carboniferous Sandstone and Coal-measure hills 

 there are sharp silicious sands.
