At Wat erf or d the canal extends acrofs 

 a long valley, the level being prcferved 

 without locks : The work is here very 

 noble : The banks of earth of a vaft height 

 and thicknefs, beautifully (loped, and the 

 whole appearance ftrikingly great. It here 

 croiTes at the fame time a large brook 

 much fubje6t to floods and a road: Two- 

 arches carry it over the flream, and a 

 third over the road. The view, Plate IX. 

 will better explain it. 



A. The ftream. 



B. The wall of the aquaedud:. 



C. The road. 



D. The floped green bank of the canal. 



E. A meadow. 



The three arches extend 80 feet. Here 

 are trap -doors, &c. as 2.1 Barton Bridge^ 

 for fecuring the water of the canal in cafe 

 cf a breach, or for repairing the aquasdud:. 



Further in the fame valley the naviga- 

 tion is carried acrofs the river MerfeJ, on 

 one arch of feventy feet fpan. 



I ihould remark, that the canal acrofs this 

 whole valley is of a vaft breadth, and has 

 rather the appearance of a great navi- 

 gable river than an artificial canal cut at 

 the expence of a fingle perfon.
