The next object that prefents itfelf, is the 

 work at Barton Bridge, which is one of the 

 principal undertakings in the whole naviga- 

 tion, and a wondrous one it certainly is. The 

 canal is here, in its ufual breadth, carried 

 (Roman aqueduct like) on arches, over the 

 large and navigable river IrwelL 



The aqueduct is two hundred yards long, 

 and thirty-fix feet wide ; it croiTes the Ir- 

 well on three large arches, the centre of 

 which fpans lixty- three feet; and is carried, 

 with amazing labour, through a valley, filled 

 tap to receive it. The view, PlateVJI. which 

 I took, flanding on Barton Bridge, will bet-

A. Is the river IrwelL 



B. A lock-gate, thro' which the barges

D. D. A gang-way from one fide to the 

 other. 



E. The canal. 



F. The pleafure - boat, drawn by one 

 horfe. 



The effect of coming at once on to Bar-

 river, with barges of great burthen towing 

 along it; and up to another river, hung in 

 the air, with barges failing upon it, form alto- 

 gether
