 defigned lowering of the banks, &c, all ap-

 the purpofe, and by no means confiftent 

 with the former plan; they are little better 

 than letting the water take its natural 

 courfe; which one would apprehend the 

 worft of all courfes, from the vaft expence 

 at which an artificial one was made. I 

 fhould fuppofe, a new cavern and well 

 would have been more confiftent with the 

 firft defign, and have anfwered the wifhed 

 for end in a more fure and regular manner : 

 and if very great floods (fuch as never yet 

 happened) are to be guarded againft, the 

 new cavern, or fubterrane, might have been 

 large enough, occalionally, to admit the 

 water difcharged by more than one well ; 

 on which plan feveral might be made to be 

 kept plugged, like the forcing ones at Q^ 

 and T, and to be opened only in floods.

 be made at Y and Zj the dotted lines
