granite blocks on the drift-hills, which seem to have came from Barnesmore. Most of 

 them were split up and utilized, principally in connexion with the quay and other im- 

 provements in Eamelton. Others occurred on the slate quarry hill near St. Johnstown, 

 about nine or ten miles S."W. of Deiry. 



In the Co. Donegal at the present time bowl-shaped corn crushers, or bullauns, are 

 in use for bruising oats for home purposes, and malt for distillation. These bullauns 

 are generally wrought out of granite or gneiss boulders ; but sometimes they have been 

 cut in the solid rock ; often in quartzyte, or quartzitic sandstone. In all cases the 

 pestles now in use are of wrought-iron, made by country smiths.] 



Polished Irish granite has of late years come into the market, 

 blocks procured from different places have, indeed, from time to 

 time been used in monuments ; hut the first permanent trade 

 seems to have been established in the neighbourhood of Newry. 

 A trade in polished granite was carried on for a few years at 

 Dungloe, Co. Donegal, which it is now proposed to revive ; special 

 quarries have been opened near Gralway town ; while the rocks of the 

 well-known Termon quarries, Blacksod Bay, Co. Mayo, are now to 

 be put on the market for polished work. 



In the quarries worked near Newry (Cos. Down and Armagh) 

 the rocks are bright and uniform greys ; those near Gralway are of 

 very variable and unusual colours, with shades of red, green, yellow, 

 and chocolate, all more or less clouded and spotted ; while those 

 from Blacksod Bay and Dungloe are brick-red, salmon, and grey, 

 with white. Near Dungloe they are capable of being raised in 

 blocks of large sizes. From various other places good stones have 

 been procured and polished ; but as yet no quarries have been 

 opened.
