Kinahan. — On Irish Arenaceous Hocks. 609 



Spademill. An old quarry, now not of note. — Some of the 

 Tbeds excellent for scythe stones. 



Ranfurly or Mullaghana. Joined by a siding to the Dun- 

 gannon Railway Station. — Creamy and yellowish ; silicious ; very 

 little cement ; fine-grained ; lasting colour ; difficult to work. 

 The quarry, after being for some time closed, was recently worked, 

 Tmt is now (1887) again closed. Was used in the Post Office and 

 Northern Bank, Belfast, and Northern Bank, Fintona ; also in the 

 addition to the Royal University, Dublin, where it has been found 

 durable and to retain its colour. 



The " Dungannon stone," from some one or other of these diffe- 

 rent quarries, has been extensively used in Dungannon. Accord- 

 ing to a list, to which I am indebted to Mr. Dickinson, some of the 

 principal buildings are : the Provincial Bank, Parish and Roman 

 Catholic Churches, Shiel's Institution, Police Barracks, and Paro- 

 chial Hall. Elsewhere it has been used at Roxborough Castle, Moy ; 

 bridge over the Ballinderry river, near Coagh (cost £5000); the 

 clock tower, and St. Patrick's Church, Belfast. " These Dungannon 

 stones, with those from Dungiven (Co. Londonderry), and Cooks- 

 town, were used promiscuously in the public offices (Post-office, Cus- 

 toms, and Inland Revenue), and the Apprentice Boys' Memorial Hall, 

 Londonderry ; also with the Dungiven stone only in the Lunatic 

 Asylum, where the stones from each quarry were used in a separate 

 building. Bloomhill, for the gate-lodge and offices ; Gortnagluck, 

 for two separate wings ; Carlan, in the doctor's residence ; and the 

 Dungiven, in two octagonal wings and the front of the old portion 

 of the asylum. In the military barracks, Omagh, Dungannon 

 stone, of the inferior quality known as the Reel-beds, was used ; 

 it works easily, but is not durable." — (J. Cockbum.) 



Aughnacloy. — Greyish to yellowish ; silicious-grained. Also 

 quarried three miles south-east of Aughnacloy. 



Qlencall. One mile from Aughnacloy. — Greyish- white ; slightly 

 stained with iron ; very silicious ; silicious cement ; a little mica. 



Brantry. Six miles south of Dungannon. — Purplish-grey ; 

 slightly variegated; semi-crystalline; granular; micaceous. 



Coal-measures. — Some of the arenaceous rocks of this sub- 

 group, unlike those that in general occur in the measures of 

 Munster and Leinster, are free- working stones. Rarely, however, 

 can they be raised profitably, on account of the "clearing" or
