OF THE COUNTY OF TYRONE* 113 



claufes in leafes would, no doubt, remedy this in fonae 

 meafure. If inrtead of the forry lime-kilns, commonly 

 called pot kilns, which we find (battered through the 

 county, fubftantial draw-kilns were introduced, there 

 would not be the leaft danger, but that lime would foon 

 become a univerfal manure. For many years back, I 

 have had roche lime, from ten pence to thirteen pence 

 a barrel, of thirty-fix gallons, whereas it is a well 

 known faft, that the farmers, in general, pay from one 

 fhilling and eight pence, to two {hillings and two pence, 

 in their peddling way of working their pot-kilns. 



A lime-kiln of what I call the compofite kind, or that 

 compofed of partly an inverted cone, and partly a cylin- 

 der, is certainly the beft conflruftion. The beft in the 

 county is at Rafh, defigned feveral years ago by the late 

 biftiop of Clogher, which conduction has fmce extend- 

 ed to other parts of the kingdom. The dimensions of the 

 kiln at Rafti are as follows : the conical part eight feet 

 high, and the diameter at bottom about eighteen inches ; 

 the cylindrical part of the fame height as the cone, 

 making altogether fixteen feet. The diameter of the 

 cylinder, and of courfe the largeft diameter of the cone, 

 is eight feet. r i he fuel ufed is turf, and, when well 

 attended, it will turn out about fifty barrels of roche 

 lime, in the twenty-four hours. There is a lime-houfe 

 attached to this kiln, of forty feet by twenty, height of 

 the walls fourteen feet ; it is flated, and colt in the year 

 1791 fixty guineas. The kiln was built feveral years 

 i before,
