the Devonians with the Lower Carboniferous Sandstone (Yellow Sand- 

 stone), and to describe the stones that occur in both together. 



These stones are very generally used throughout the county, 

 either for cut-stone or rubble purposes. The stones usually are 

 shades of brown, green, and yellow. In the west of the county 

 different varieties of stone are very much mixed up ; as quite 

 distinct stones very often occur together in one quarry. At 

 Skorough, eastward of Lismore, in one quarry, there are four 

 varieties, interstratified, ranging from finely-laminated slate to a 

 gritty sandstone. A soft, earthy, f elspathic, and micaceous stone, 

 from Ballysaggart, was used in the dressings of the Eoman Catho- 

 lic Church, Lismore ; while, about three miles eastward of the 

 town, in one quarry there are roofing-slates, good flags, and free- 

 stone, all of which were formerly worked. These slates, however, 

 were eventually cut out by the Welsh slate. In the same town- 

 land, but nearer Lismore, there is a stone fit for cut- work ; but it 

 varies in quality, the best being in beds from two and a-half to 

 three feet thick. There are also other quarries, nearer to the 

 town, but difficult of access. For the buildings in Lismore sand- 

 stone has principally been used ; but in the church erected about 

 fifty years ago limestone was used, and also in the mullions and 

 windows of Lismore Castle. 



Glenniveene. About five miles from Lismore. — Flags ; difficult 

 to dress, as they are liable to chip at the edges. 



Slieve-Grian. In different places. — Light-coloured, silicious, 

 felspathic cement ; slightly micaceous ; even-grained ; porous ; 

 good quality; works freely. Very generally used for dressed 

 work in Dungarvan, from which the quarries are distant some 

 seven to nine miles. 



In Cappoquin, the stone most used is a local thin-bedded, 

 gritty, silicious, speckled sandstone. 



Cappagh. — An excellent dry stone, but difficult to work, as it has 

 no regular bedding or soles. Used in the new house at Cappagh. 

 Green flags have also been procured in the neighbouring hills. 



Ballyharahan and Killongford. Near Dungarvan. — Brownish 

 and yellowish, but more usually variegated. Generally soft, fine, 

 argillaceous, and micaceous on the bedded surfaces ; porous, and 

 easily worked. In the quarries there are some subordinate, 

 felspathic, and more coarsely-grained beds, from twelve to fifteen
