Irish Localities for Paving-setts. — Having personally visited 

 most of the quarries from which paving-setts are now being 

 obtained, I will, in conclusion, give a short account of each, 

 commencing at the north coast of Co. Antrim. 



Ballintoy Quarry. — This quarry is worked by the Eglinton 

 Chemical Co., Limited. The rock consists of a largely-crystalline 

 dolerite, forming a cliff 80 feet in height, in rude columns, and 

 about 200 yards in length. The stone is shipped at the little 

 harbour of Ballintoy and sent to Glasgow, Londonderry and other 

 places. It consists of a crystalline aggregate of augite, plagio- 

 clase, olivine, and magnetite. I understand that paving-setts could 

 be delivered in Dublin, at 22s. per ton. 



Ooragh Wood.'— This quarry belongs to Messrs. J. Eobinson 

 and Son, of Belfast, and is opened by the side of the Great 

 Northern Railway at the junction for Newry and Armagh. The 

 rock consists of fine-grained granite of quartz, felspar, and black 

 mica in small flakes. The paving-setts are sent to Belfast and 

 other parts of Co. Antrim, and have likewise been used in Man- 

 chester, Oldham, Liverpool, Rochdale, and other towns in England ; 

 and the stone for building and decorative purposes, takes a fine 

 polish. It can be delivered in Dublin at prices varying from 

 18s. 6d. to 21s. per ton, according to the size of the " cubes." 



The Castlewellan granite is considered more suitable than the 

 Goragh Wood stone for paving, being somewhat harder; and is 

 being used by the Belfast Harbour Commissioners for paving the 

 street along the Donegall-quay, where the traffic is naturally 

 heavy. For building purposes the stone was selected, amongst 

 other places, for the Bishop Rock Lighthouse at St. Mary's Island, 

 Scilly. Paving-setts of this stone can be delivered in Dublin at 

 prices varying from 19s. 6d. to 22s. per ton, according to the size 

 of the " cubes." 



Bessbrook, near Newry. — These quarries, which belong to the 

 Bessbrook Granite Co., Limited, are opened in granite, consisting 

 of quartz, felspar, and black mica in small flakes. The rock is ex- 

 tensively worked both for setts and also for building and ornamental 

 purposes, and the stone is shipped at Newry, or sent by rail. I 

 understand the company have offered to supply paving-setts to 

 Dublin at 22s. 6d. per ton, though the regular price is 24s. The 

 stone is used in various parts of England, including Manchester,
