The " Carlow Stone," which has been so largely sent by canal 

 and road to Dublin, Waterford, Kilkenny, and intermediate places, 

 has been procured from a tract about ten or eleven miles long, and 

 from three to four miles wide, extending from Ballybegs, about 

 seven miles N.E. of Carlow, south-westward to Ballywilliamroe, 

 east of Bagenalstown. 



In this area excellent surface-stones have been procured, 

 especially at Crane, Kildranagh, and Battymlliamroe, respectively, 

 five to eight miles N.E., and two miles E. of Bagenalstown, the 

 blocks vary in magnitude to ten tons and upwards, while some 

 stones have been raised from workings. " In Bagenalstown, granite 

 is the material generally used for cut-stone purposes, the solid stone 

 being close to the town on the east." (Wilkinson.) 



Ballybegs, about seven miles north-east of Carlow. Grrey to 

 yellowish ; more or less felspathic ; micaceous ; some portions 

 liable to discolour with iron. This quarry was formerly very ex- 

 tensively worked. Of it Wilkinson, writing in 1845, states : 

 " This is the only quarry in the county sunk to any depth for 

 procuring this stone. The quarry is about 40 feet in depth, and 

 covers an area of about 300 square yards. The stone is procured 

 in large, irregular blocks ; the joints running nearly perpen- 

 dicular, or at an angle of about 15°." 



Kildranagh, about six miles north-east of Bagenalstown. 

 Coarse, very felspathic ; mica black and grey ; lumps of semi- 

 crystalline quartz. ( Wilkinson.) 



Newtown, about three miles east north-east of Bagenalstown. 

 Felspathic ; micaceous ; some schorl ; felspar rather reddish. ( Wil- 

 kinson.) 



Kilcurragh, near Bagenalstown. Grrey to nearly white ; loosely 

 aggregated ; felspar white and opaque ; quartz ; white, mica 

 grey. ( Wilkinson.) 



In places near the margin of the granite, and in the associated 

 schists, are el vans, sometimes so fine as scarcely to be distinguished, 

 in a hand specimen, from a felspathic grit; while others are more 

 granitoid. (Jukes.) This variety is fine and very micaceous. It 

 attracted Wilkinson s attention, as it appears to have been much 

 used by the early builders, it being more easily worked than the 

 ordinary granite. From him we learn that in the old Wells 

 Church, a mile and a-half south-west of Bagenalstown, it was
