THE GEOLOGIST. 



gowlan, and its proximity to that of Greaghnaslieve, it is evident that 

 the whole of this coal-bearing area should be worked from the 

 northern side of the mountain. I believe that the quality of the 

 Greaghnaslieve coal is the same as that from the Seltanaveeny Pits. 



3. The Seltanaveeny Coal-field. — Extensive operations have been 

 carried on here for many years back in the northern part of this 

 townland, adjoining that of Tullynahaw, and shafts to the depth of 120 

 feet have been sunk in the coal ; from the comparatively low position 

 of this ground and the fact that this portion of the coal-field is formed 

 by the stream S.E. end of the Altagowlan basin, and the coal at its 

 outcrop dips to the hill in every direction, great difficulty will ever be 

 experienced in freeing the workings of water. (See map.) 



The distance to the lake from those pits is four miles, by the new 

 road to Greaghnaslieve, or two and half by the old and at present 

 broken-up road leading from Tullynahaw colliery.
