*e STATISTICAL SURVEY 



tible. I have obfcrved a chalky fubflance to adhere to 

 much of the limeflone about Cook's-town, which does 

 not render it the worfe for either manure or cement. If 

 the flone be broken very fmall, and applied to land, 

 it is found to anfwer very well without calcination. 

 Here, and throughout a great part of this barony, 

 limeftone is burned with culm, or fmall coal, inflead 

 of turf. At Benburb, culm generally fells at 1 8/. by 

 the ton, and the lime-meafure here is thirty-two gal- 

 lons, which is commonly fold at is. -j^d. per meafure 

 roche, or unflacked. 



This barony is by no means deflitute of freeflone, 

 which is fully demonflrated by the towns of Dungan- 

 non,jCook's-town, &c. 



The barony of Omagh is not very rich in limeflone; 

 the principal quarries are in the parifti of Longfield, 

 which are inexhauflible, as are alfo quarries of free- 

 flone of an excellent quality. The mofl part of the 

 county is fupplied with mill-flones from the rocky 

 mountains about Drumquin, in this parifh. Mill-flones 

 are fcldom got in regular quarries in this neighbour- 

 hood ; they generally are hewn out of fingle detached 

 rocks. Mountain or grit-flone is befl calculated for 

 mill-flones. 



About Clogher, and many parts of the manor 

 of Aughentaine, and alfo about Ballygawley, both 

 in the barony of Clogher, are very rich in Jimeflonc,
