In such a Kiln, may be burnt 480 bushels of lime per week, 

 and this will consume 15 quarters, or 120 bushels of refuse coals, 

 such as is not commonly used for any houshold purposes. The 

 coal costs at the pit twopence per bushel, and the distance being 

 six miles, the carriage is threepence, the prime cost of the lime 

 therefore is fourteen pence per quarter, as the following calculation 

 shews :

The lime produced by one of these kilns, will amply manure 

 3 acres per week ; and I leave my readers to determine, whether 

 kilns of this construction are, or are not to be prefered, to those 

 in shape of an inverted cone. The largeness of the surface in the 

 last mentioned, must I should think, require coal of a better qua- 

 lity, and consume a greater quantity. 



Lastly, let us take a view of the public roads. They are left 

 40 feet wide, and are stoned 1 2 feet. 



It is usual to stone these roads one foot thick in the middle, and 

 nine inches at the sides making thereby a gentle curve.
