Kinahan — On Granite and Mctamorphic Rocks. 199 



No. 2, 5" x 5" x 5" ; No. 3, 5" to 8" x 3" x 6 ; and No. 4, 5" to 9" x 

 4" x 7". The stones are not in sizes large enough for channels, 

 kerbs," &c. {W.Kerr.) 



To the north of Arklow, at the Lewisville granite, near Snug- 

 borough, and in different other places in the parishes of Kilbride, 

 Ennereilly, Dunganstown, &c, there are stones of good aspect, 

 but as yet untried. One variety rises in flags, and has been used 

 for flagging in Arklow and the country farm-houses. 



[The polish which the whinstones are capable of receiving and retaining can be 

 studied by examining blocks and pieces in the glacial drift.] 



Little Rock, Arlcloic, mass to the south of the hill. Nice-look- 

 ing, mottled greenish, granitoid. 



In the neighbourhood of the Ovoca mines there are great 

 masses of " baked rocks " (leptinyte and granulite) mixed up with 

 felstone, and often difficult to distinguish from one another. Some 

 of these rocks, as pointed out years ago by Weaver, are suitable 

 for the manufacture of kaolin (porcelain clay), while others can be 

 cut and polished. A specimen from Bell Rock, south of the mines 

 adjoining the tramway, gave a nice, streaked and mottled, light 

 dove- coloured stone, that cut well and took a fine polish. Very 

 pure leptinyte, suitable for the manufacture of kaolin and of 

 glass, occurs in various places adjoining the intrudes of whinstone ; 

 these felspathic rocks also occur, more or less isolated, as in the 

 vicinity of the Ovoca mines. The latter have not been made use 

 of, although attention was directed to them more than half a cen- 

 tury ago by Weaver. 



Others of the shales have been baked into a black rock like 

 touchstone, pieces of which have been manufactured by Mr. 

 Russel, lapidary, Fleet-street, Dublin, into touchstones and into 

 whetstones for the finer stone-cutting tools.

Granites. 



In the granite tract which lies to the south-east of the county, 

 no large quarry has been opened in recent years on account of the 

 number of surface-blocks of a superior class which occur there.
