Cloghreen, although, the latter is in the limestone. A brown sand- 

 stone from these hills was used in the ancient castle at Cahir. 



Mount Anglesey. A few miles from Cloghreen. — Brownish- 

 yellow ; silicious-grained ; argillaceous cement ; fine, but granular ; 

 friable ; works freely and well ; used for quoins, jambs, and other 

 dressings ; can be raised in long scantlings, and is capable of long 

 bearings. 



In the slopes of the Graltees, included in this area, good stones 

 occur in numerous places : they vary from whitish to reddish and 

 brownish in colour, some being more silicious than others. In 

 general they work freely, and have been used in Cahir in pre- 

 ference to the limestone. These were used in the repairs of the 

 old castle some forty or fifty years ago. 



Carboniferous. — Lower Carboniferous Sandstone. These stones 

 range from coarse reddish or brownish conglomerate to fine sand- 

 stone, in shades of light yellow, reddish, and brown or purplish. 

 In Clonmel, where sandstone has been most used, it has been pro- 

 cured from the other side of the Suir, in the Co. Waterford. A 

 similar remark is applicable to Carrick-on-Suir. 



Tinnakilly. Six miles north-east of Carrick-on-Suir. — Yellow 

 to brownish ; silicious-grained ; with little cement ; ferriferous ; 

 very slightly micaceous. From here, and from Millvale, Co. 

 Waterford, have been procured most of the sandstone used in 

 Carrick. 



Dundrum. About a mile from. — Yellowish-grey ; very good 

 texture ; suitable for all kinds of dressed work. Mr. Sharp, the 

 well-known Dublin builder, states that he believes this stone would 

 be very generally used if it were known. 



Drumbane. About seven miles southward of Thurles. — "Whitish 

 or light-grey ; quartz-grains ; argillaco- silicious cement ; slightly 

 ferriferous ; works freely ; can be raised in large scantlings. Was 

 used in the Court-house, Nenagh, twenty miles distant, and in the 

 Model School, Clonmel. This, like the Dundrum stone, ought to 

 be more generally known ; it is an admirable material, more 

 durable than limestone, and very suitable for staircases, as it can 

 be obtained in nearly any scantlings, and is capable of long 

 bearings. 



Carrick. Near Eoscrea. — Light-brown; silicious; very little 

 cement; fine-grained; dense.
