and morassy, that it gives way to the superincumbent clay, and 

 rises up in the middle of the drain. 



This cut from the Dunbald sluice to the moor (a distance of 

 about two miles and a half) cost four-pence per cubic yard, or in 

 the whole about three thousand two hundred pounds ; from thence, 

 the price diminishes in proportion to the depth and width. Expen- 

 sive as this undertaking inevitably must be, yet the benefit result- 

 ing from it, will most amply repay ; for without saying any thing 

 of the injury done to the health of the inhabitants in the cireum- 

 adjacent country, and which this drain, by, rendering the air more 

 salubrious, will totally remove ; we may fairly state, that the 

 probable improved value cannot be estimated at less than four hun- 

 dred and fifty thousand pounds. 



Though the total amount of expenditure cannot with precision 

 be ascertained ; it may give some satisfaction, if I inform my 

 readers, the probable sum total thereof. The following statement 

 of the account Dr. and Cr. will approach pretty near the truth; 

 but let it be understood, that this calculation is made under the 

 idea of parochial subdivisions, without which little benefit v ill re- 

 sult either to the public, or individuals. The principles which I 

 have in my report on the North East District fixed as data, in- 

 controvertible, viz. That all commons, however rich and fertile 

 the soil, are unproductive of profit, in consequence of overstock- 

 ing, must be here adhered to, and this argument is equally appli- 

 cable to old inclosures. Let a farmer put ten head of cattle into a 

 given piece of ground where ov\\y five should be depastured, and the 

 cattle will be of less worth, after the grass' is consumed, than they 

 were before : Of what value then is the land ?
