make a little more than a mile ; this is only 

 one pound five fhillings. If eighteen inches 

 broad and deep, at twopence per rood, would 

 be two pounds ten fhillings for one mile. If 

 fixpence per rood, feven pounds ten fhillings. 

 If five foot wide and three deep, at one {hil- 

 ling, fifteen pounds per mile ; and fo on in 

 proportion. 



Now, let any perfon confider the expence, 

 and advantages arifing from watering, per- 

 haps fome hundreds, or a thoufand acres by 

 this cut. The longer the water has to run, 

 the cut would need to be wider and deeper. 



This cut might anfwer in part for a drain 

 to the grounds above, if thofe below were a 

 dry foil, and mofs above the cut. The fmall 

 mofs might be turned into the water, which 

 would enrich the fields below. Even a rich 

 clay, rock, or fhell marl, might be mixed 

 with the water, and by thefe means enrich 

 the plains below. 



One perfon could manure many hundred 

 acres in one year, by mixing whatever foil 

 was above with the water. This would fave 

 the trouble of carting it down theliill.
