working ; many houses in Clones and Lisnaskea are built of this* 

 stone ; but the quarry seems to be now closed. 



Slush Sill. Two miles from Lisnaskea. — Greyish-white and 

 yellowish ; silicious-grained ; scarcely any cement ; ferriferous 

 stains ; some beds very friable ; easily worked. Some fifty years 

 ago this was the principal sandstone used in Enniskillen, Clones,, 

 and Lowtherstown (now Irvinestown). Dartry mansion, Co. 

 Monaghan, and Farnham, Co. Cavan, were built of stone pro- 

 cured here. Now, however, the quarry is not worked, on account 

 of the " overbaring." 



Kilturk, or Mount. Between two and three miles from Lis- 

 naskea. — A somewhat similar stone ; splits into long scantlings. 

 Nearly all the gate-posts and the cut stones for the buildings of the 

 Great Northern Railway westward of Dundalk were procured from 

 this quarry. 



Knockncdossett. Seven miles from Lisnaskea. — The stones for 

 Monaghan College and smaller buildings were procured here. 



Crocknagowan. Two miles from Lisnaskea. — Stones used in Pres- 

 byterian churches, Belturbet and Aughnamullan, Co. Monaghan, 

 Clones Gas Works, and Tempo House ; also wrought into tomb- 

 stones. 



Eshbralby. Three miles from Lisnaskea. — Stones used in Inish- 

 more Hall, and for pillars and dressing in Crom Castle, and in the 

 new work, Enniskillen Church. It is also wrought into tombstones, 

 and some of the beds into scythe stones. 



Altnabroclc, or Aughnabroch. Near Lisnaskea. — Clean, fine- 

 grained, and massive ; Ulster Banks, Enniskillen, Lisnaskea, and 

 Clones ; seems to be much sought after at the present time. 



Corraghy, or Elclerioood. Three miles from Brookborough. — Not 

 in repute for cut-stone purposes. 



Cammore. — Pebbly, silicious sandstone ; good ; hardens on 

 exposure ; easily worked when first raised. This stone formerly 

 was extensively wrought into mill-stones and flax-crushers before- 

 these industries declined. 



To the north-east of Lough Erne, in the Calp of the " Ulster 

 type " of the Kesh district, there are good stones to be procured in 

 Inishbo (Cow Island) in the north portion of the lake, and in 

 different places north-east of Kesh. According to Mr. Plunkett,
