at present, the Ballinasloe stone having 1 , in a great measure, taken 

 its place. This seems to be due to the cheaper carriage of the 

 latter stone. 



Lime, in general, is very good and cheap in the King's County. 



Leitrim. 



Although a large portion of this area is limestone, yet this 

 "being, in general, of a calpy character, the best cut-stones are 

 usually brought from the neighbouring counties. The caps on 

 the gate-posts of the King's Demesne, near Drumsna, came from 

 Ballinrobe, in the Co. Mayo. In the north portion of the county 

 there are in some places very good stones, but no quarry of more 

 than local note seems to be worked. 



Meahoood. — Three miles and a-half from Carrick-on-Shannon. 

 Greyish-blue; crystalline; compact; splintry ; difficult to work: 

 large blocks can be procured. Formerly this stone was much 

 used, but of late better stone is brought from Hughes' Wood, in 

 the Co. Roscommon. 



Castleslavin. Three miles from Carrick-on-Shannon. — Whitish- 

 grey, crystalline ; fairly easy to work ; retains its colour. 



BalUnamoe. — The stone here similar to that at Mealwood. 



Kilbride. — One mile from Drumsna. Bluish- grey; not very 

 good for tool-work. 



Lime in this county good; of superior quality near Manor- 

 hamilton. 



Limerick. 



More than half of this county is occupied by limestones of dif- 

 ferent qualities, the rocks being more distinctly and regularly 

 grouped than elsewhere in Ireland, as previously pointed out 

 (page 375}. Margining the exposure of sandstone is the dark- 

 blue, coarse, grey bedded Lower limestone, having over it the 

 unbedded Fenestella limestone, and above that the Calp, ranging 

 from a coarse slate and shale to marble ; and above all, under the 

 Coal-measure shales, the Burren-type rock. 



Corgrig. A little S.S.E. of Foynes. — Dark-blue and grey, 

 crystalline ; in part earthy ; works fairly well ; flat-bedded ; ca- 

 pable of being raised in very large blocks. Used extensively in 

 pier- work on the Shannon, both in Clare and Limerick.
