and the road along its side. 1 Another strong timber 

 aqueduct, 460 feet long and 17 feet high, conducted the 

 New River over the valley near where it entered the 

 parish of Islington. This was long known in the neigh- 

 bourhood as " Myddelton's Boarded River." 2 At Is- 

 lington also there was a brick tunnel executed for a 

 considerable distance, and another at Newington. That 

 at Islington averaged in section about 3 feet by 5, and 

 appears to have been executed at different periods, 

 in short lengths. Such were the principal works along 



though these were not erected at equal 

 distances. Between every two of 

 these piers an equal number of im- 

 posts and uprights were fixed, resting 

 on piles of similar dimensions on the 

 basement timbers of the frame, liobin- 

 son, in his 'History of Mdmonton,' 

 says that in the year 17SO, during 

 the riots in London, the rioters 

 threatened to destroy this aqueduct, 

 luit, on application to Government, a 

 party of cavalry was sent down to 

 guard it, and they remained there 

 some days. 



1 This was considered one of the 

 most important structures belonging 

 to the original New River works. 

 Salmon ('History of Hertfordshire/ 

 p. 20"), speaking of the "great ex- 

 pense "at which the river was made, 

 observes of this brick arch and aque- 

 duct that " it is said to have cost 

 500/." ! It was evidently regarded as 

 a great work in its time. 



~ These troughs were both removed 

 by the late Mr. Mylnc, Engineer to 

 the New River Company, and clay 

 embankments substituted.
