Kinahan — On Irish Arenaceous Rocks. 583 



Brumquin. — Yellowish, fine-grained, works freely ; when raised, 

 very wet, but dries on exposure ; not very durable. This stone 

 was formerly much used in Coleraine and Limavady. 



Altmover. "West of Dungiven. — Various quarries, varying 

 from white and creamy to reddish greenish-grey; semi-crystal- 

 line ; argillo-silicious cement ; some beds with sand holes. Thin- 

 bedded stones used as flagging in Limavady. 



From these and other quarries are procured the stones known 

 as the Dungiven stone; and in these different quarries special 

 beds must be better than others, as there is a diversity of opi- 

 nion as to its quality. From a quarry then known as " Bally- 

 hagan" were procured most of the stones for the Bishop of Derry's 

 (Lord Bristol's) palace at Ballyscullion ; but the portico was built 

 of Ballycastle (Co. Antrim) stone (page 532). To the north of 

 Dungiven a quarry has been opened of late years, from which a 

 very superior stone is procured. 



Of the stone sent to the Belfast district Mr. Grey states : 

 '" This is very excellent stone, of light colour, free from iron, 

 very durable, hammers and tools well ; works freely for dressings, 

 sills, and quoins, as well as for rubble work. Has been used in 

 Coleraine Church ; in Parish Church, Northern Bank, and Pres- 

 byterian Church, Kilrea; Protestant Hall, Belfast; and in the 

 Coastguard Stations at Moville and Eathmullen, for quoins, sills, 

 and dressings." 



They have also been used in the Diocesan Seminary, London- 

 derry ; in the Lunatic Asylum (see Oortnagluck List, Co. Tyrone, 

 page 608) ; in St. Columb's Cathedral and the Eoman Catholic 

 Parochial Hall. The Provincial Bank, Ballyshannon, Co. Donegal, 

 was to have been faced and dressed with Mount Charles stone ; 

 but, when it was half up, the supply seems to have failed, and 

 the cut- stone in the upper portion is from Dungiven. Of the 

 latter Mr. J. Cockbum writes : " The stones seem to have been 

 carefully selected, as they are better than most specimens of it to 

 be seen elsewhere in evenness of texture, firmness, uniformity of 

 colour, and freedom from sand holes." They have been used for steps 

 and dressings in different private residences in north-east Donegal. 



Glenconway. Eight miles from Limavady. — Yellowish ; easily 

 worked; has been used in Limavady, Londonderry, and else- 

 where.
