 is drawn ^ in many places it is conveyed fourteen miles 

 by land-carriage from the kilns; in others limeftone is 

 drawn and burned upon the farm ; in this way, when 

 fuel is near, much is faved, as the expenfe of drawing 

 is the moft material, the (tone being purchafed at the 

 quarries at not more than fixteen pence per ton; when 

 it is brought by water, either by means of the canal, 

 or from Carlingford to the eaft coaft, the price is from 

 3.r. 6d. to 5-r. per ton. In the neighbourhood of Bally-

 of three kinds are often feen at a fmall diftance from 

 each other, the blue from Carlingford, the red from 

 Caftle Efpie, not far diftant from Comber, and the 

 white from Moira, fourteen miles; of thefe the white 

 is reckoned to produce the greateft quantity of lime 

 from a given weight of Aone. The price of lime at 

 the quarries, where it is burned, is from is. id. to is.iJ. 

 per barrel. I have been lately informed by feveral

 mufl caution the farmer once more againfl the perni- 

 cious practice of repeated crops of grain, without the 

 intervention of grafs or fallow. The ufe of lime as a
