dispersed over trie county, many quarries capable of producing a 

 good class of stone. 



Crisnagh. Near Boyle. — Grey ; semi- compact ; crystalline; 

 works well and freely. 



French Park. Near Boyle. — Grey; close, and compact; a free- 

 stone ; works well. The quality of the stone near Boyle, and its 

 suitability for tool work, were not formerly recognised. When 

 Rockingham House was built, the stones were brought sixteen 

 miles from Ballinafad, Co. Sligo. Some of these stones polish 

 well, and are used for tombstones. 



Hughestoicn. A few miles from Carrick, near the Shannon. — 

 Light greyish-blue ; some of a better class become of a lighter 

 colour when worked. This stone has been used in Carrick-on- 

 Shannon in preference to the stone at Meal wood. 



Castlereagh. — Between this town and Boyle there are different 

 quarries ; but the stone is more or less of a Calpy nature, and diffi- 

 cult to work. Mount Sandford House, near Castlereagh, was built 

 of stone brought from Bellanagore, about nine miles distant. 



Bellanagore. Seven miles from Elphin, the quarries being 

 situated a few miles to the west and south-west of the village. — 

 Dark to light grey ; much freer than the stones near Castlereagh ; 

 but inferior to those near Boyle. 



Angiitis. About two miles from Roscommon. — Dark to light 

 grey ; fine ; crystalline ; works freely. 



Scardaun. About four miles from Roscommon. — Dark to light 

 grey ; works freely ; in character very like those of the barony of 

 Burren, Co. Clare. 



Lecarrow (Knockcroghery). — Grey; finely crystalline ; regularly 

 bedded ; in parts cherty ; works fairly well. 



Taghmaconnett. — In this stony district the rocks are of types 

 similar to those in the barony of Burren, Co. Clare. Good stones 

 might be procured, but no quarry of note has been worked, as the 

 stones needed in the neighbouring towns of Athlone and Ballina- 

 sloe are more easily procured at the latter, in the Co. Gal way, and 

 at Clonmacnoise, in the King's County. 



The lime in this county is excellent and cheap.
