Ordovician slates was also worked in the south-west part of 

 Lisnadill parish. 



In the Devonians a red bed was considerably worked near Clash- 

 more, in the valley of the Lickey. In places in the vicinity of 

 Lismore slates of this age were also worked, the quarries being more 

 fully described hereafter ; also in Glcnribbon, north of the Black- 

 water, and on the slopes of Knockmealdown ; the slate was of good 

 quality, but the veins of small dimensions. 



WEXFORD. 



In the Cambrians of the Forth Mountains, about a mile east of 

 Trinity cross-roads, a nice-looking blueish-grey slate is recorded ; 

 but it is as yet untried. — (g. s. m.) 



In the Ordovicians, a mile and a-half S. S. W. of Bunclody, or 

 Newtownbarry, in the townland of Ballyprecas (Hall-Dare), and 

 Glaslaclxen (Digby), north and south of a glen, slates are found. 

 The veins are peculiar ; because, although the quarries are opposite 

 one another, and seem to strike one at the other, the slabs are quite 

 different ; those to the north, in the Hall-Dare quarry, being blue 

 and ribboned, while those to the south, in the Digby quarry, are 

 grey or greenish grey; a grey vein in the latter is of excellent 

 quality. 



At the present time these quarries are smothered up, and are 

 only worked in a very small way ; yet there are great facilities for 

 opening a good quarry — that is if a deep cutting was made up the 

 glen from the westward, by means of which the veins would be 

 drained to a considerable depth, while the waste could be run out 

 into the valley to the westward and the veins both to the north and 

 south economically worked. 



In Slievebawn, the hill about five miles north-west of (xorey, 

 and immediately westward of Hollyford, there are considerable 

 veins of slate. To the westward, near Mouaseed, there are various 

 small workings ; and although none of them are deep or of great 

 extent, yet a very fair slate has been procured, with every prospect 

 of a superior slate in depth. The veins could be easily driven on, 

 either from the eastward or westward, and the opening and working 

 of a quarry ought not to be expensive.
