quarry men, as without them there would be a considerable loss 

 from the waste of good material in getting out the blocks. 



Other quarries in this vicinity are — that at Laghtea, about two 

 miles S.W. of Portroe, in which there appears to be a good small 

 vein ; two small quarries, north of Tountinna, near the " graves of 

 the Leinster men " ; The Gap, which lies a little east of the last ; 

 Berry Castle, a large quarry worked by the " Imperial Company: " 

 there is said to be in these slates a " wind," in consequence of 

 which they are liable to cast up ; it was for this reasou that the 

 Oompany purchased the Corbally quarry ; a quarry one mile south 

 of Derry Castle ; and a quarry half a mile N.W. of Ballina. In 

 the last the slate is of a very superior quality, but it has an off- 

 baring of twenty feet in thickness, of a massive green grit, which 

 made the slate very expensive to work. Other small openings 

 were made in this vicinity ; but the slate was not of much value, 

 as regards either quantity or quality. 



TYRONE. 



North-east of Pomeroy, at the village of Slate Quarry, roofing 

 slates were formerly obtained, but they were poor, being small, 

 heavy, and rough. 



WATERFORD. 



Four and a-half miles east of Kilmacthomas are the Ross quarries, 

 which were worked up to 1863 ; the slate is good, of a dark-grey 

 colour. 



In Glenpatrick, six miles from both Carrick and Clonmel, there 

 were, before 1850, rather extensive quarries on veins of Ordovician 

 slate. The largest are Toor, to the north, and a quarry 300 yards 

 to the south of Glenpatrick bridge. In the former the slate is fine- 

 grained, of a bright bluish-grey, and in the latter of a lighter grey. 

 The veins in both are of a good width. 



A third quarry is situated in Clondonnell, at the base of the 

 Reeks of Glenpatrick, on a vein of finely-cleaved, earthy, grey slate. 



The slates in this glen seem well worthy of being re-worked, 

 more especially on account of the nearness of the river Suir, which 

 is there navigable for boats ; but they ought to be worked on better 

 principles than formerly.
