The old courfe of the Medlock is marked 

 out by the lines dotted thus : 



Inftead of permitting it to continue in that 

 courfe, it was enlarged into the fize it now 

 appears in the plan, the circular end ol 

 which is all raifed on mafenr) . The out- 

 ward line of the wear, K, K, K, regulates 

 the height of water in the canal ; the higher 

 that edge is, the higher is the water. The 

 river Medlock , thus enlarged, falls fitteen 

 inches over that edge of mafonry, into a 

 fredi furface of water, marked L, L, L; 

 this is likewife all raifed of ftone-work; 

 near the center of it is a well M of eleven 

 yards diameter, down which the whole river 

 falls feveral yards depth. It is received at 



horfe, is now firm and dry, and has been plowed 

 with eafe. My meadows thus drained wear a 

 new face, and I would particularly recommend 

 this mode of draining for grafs grounds.
