Bat there are others works at Barton 

 which claim our attention, befides the croff- 

 ing the river. Two roads here came athwart 

 the navigation, and happening in this val- 

 ley, where the canal is lb much higher than 

 the level of the country, to have built bridges 

 would have coil immenfe fums, as the rife 

 would have required them half as long as 

 that at Wefiminfier. The method, there- 

 fore, taken by Mr. Briruiley, was to fink the 

 road gradually on both fides, and turning a 

 large arch, to carry the canal over the roads 

 as well as the river : and this is practifed 

 with both. So that in going under it you 

 fink gradually on one fide and rife in the 

 fame manner on the other. The view, PL 

 VIII. will explain it clearly. 



A. Is the canal. 



B. The wall that fupports the arch. 



C. The road. 



Leaving this fcene of wonders, we paffed 

 on, and coming to Moreton Bridge, we pre- 

 fently faw a frem inftance of attention, to 

 keep the water of the canal unmixed by 

 that even of the fmalleft flream, for here an 

 arch is turned under the canal, for a little 

 brock to run through. 



Towards the brick kiln on the right, 

 and paft it, I obfervcd fome lands lying 

 very low, beneath the level of the canal ; 

 in wet feafons they tnuft be much damaged 

 by the water of the navigation.
