Kilkenny. A similar stone occurs near Rosenallis, at the foot of 

 Slieve-Bloom. Both are excellent for inside work. The fine-cut 

 stone house of Castletown, near Carrick-on-Suir, built by Arch- 

 bishop Cox more than one hundred years ago, has the south front 

 of a darkish sandstone, apparently got in the neighbourhood. 

 The Coolnahan conglomerate, above mentioned, rises in large 

 squared blocks, eminently suitable for the coping of quay walls 

 and such like works, as do also the rocks in the glen at Catsrock, 

 near Tory Hill. 



Aghavaller Eound Tower is built of a brown, slaty-textured 

 grit stone, in irregular courses. 



Ordovician. — The grits and sandstones in this group are 

 almost invariably hard and splintery, not being adapted for cut- 

 stone purposes. They are, however, used for rough local work. 



Carboniferous. — Very excellent stones occur in various places 

 both in the Lower Carboniferous Sandstone and in the Coal-measures, 

 as just now mentioned. The hill of Drnmdoioney was formerly 

 famous for its millstones, which were said to be equal to the 

 French. They were sent by water to England, Dublin, Cork, 

 Waterford, and elsewhere. Some of the largest were 5 feet in 

 diameter, and 16 inches in the eye. They were shipped with ease 

 on the Barrow, at the base of the hill. The last stones, wrought 

 about 1876, are in Saul's Mills, near the locality. On the same 

 hill there was also a vein of white stone, fit for all cut-stone pur- 

 poses of small dimensions. 



Lower Carboniferous Sandstone. — Baunbree. Near Scagh 

 cross-roads, four miles from Carrick-on-Suir. — Brown, reddish, and 

 yellowish ; kind ; apparently durable ; used in the Roman Catholic 

 church at Tallaghast. 



Annefield, or Tullynacranny , and Oldcourt. Five miles from 

 Carrick-on-Suir. — Yellowish. The stones, except the quoins, which 

 are limestone, for Pilltown New Church were got from Bregaun 

 Hill, near the Annafield plantation. 



Drumdoney. Four miles from Waterford. — Red sandstone. 



Mr. P. Burtchael, County Surveyor, points out that, although 

 there are now no quarries open, good stone ought to be procurable 

 from the Lower Carboniferous Sandstones in the neighbourhood of 

 Thomastown, Jerpoint, Kiltorcan, and Callan, as attested by the 

 ancient ecclesiastical and other structures. At Coolhill, near Kil-
