Kinahan — On Irish Arenaceous Rocks. 571 



sandstones to be easier worked than the limestones, but not as 

 durable. 



From near Glenbehy were procured the stones for the ashlar 

 work in Aghadoe, Lord Headly's mansion, near Killarney, built 

 some fifty years ago. 



Coal-measures. — As already mentioned, there are excellent 

 stones in places in this area, but now in general superseded by the 

 limestone. At Barleymount is a quarry, from which the stone was 

 taken for walling-in Aghadoe mansion. 



Armagh. North of Milltown. — A quarry in a good brown 

 stone. 



In different places in the " Flagstone series," near the base of 

 the Coal-measures, flags have been raised. They are not, how- 

 ever, as well developed as in the Co. Clare, to the north of the 

 Shannon ; while there is nearly invariably a considerable "head" of 

 drift, that makes them expensive to quarry ; consequently, they 

 are rarely looked after, it being cheaper to use the " Clare flags." 

 At Ballylongford there are fair flags, with black shale partings, at 

 one time quarried for the general markets ; while elsewhere are 

 small quarries, that were opened for local purposes. 



Sand and Gravel. — Pit sand and gravel occur near Kenmare, 

 near Tralee, and in the neighbourhood of Killarney ; while good 

 river sand is procurable in most of the rivers and streams, especially 

 those having their source in Slieve Mish, which carry down a red, 

 sharp, clear sand, used extensively in Tralee. 



In several places on the coast of Tralee Bay is a sea sand, 

 which is used in Tralee with the stone saws for cutting blocks. 



JEolian sand dunes occur in places along the coast. Formerly 

 the calcareous varieties of these sands, as also the shell sands 

 dredged up in the bays and the estuary of the Shannon, were 

 highly valued as manure, especially for boggy land. These used 

 to be carried for great distances inland on horseback, even across 

 the hills into the Co. Limerick. 



Glass. — There seems to be no records of glass being manufac- 

 tured in this county, although some of the fine sands from the 

 Devonian hills seem well suited for the purpose.
