590 Sutton Wash Embankment. 



well conducted public work has produced very beneficial 

 effects in point of drainage. The bed of the river for 

 9 miles upwards is lowered 5 ft, which has caused many 

 other internal improvements, particularly the lowering of the 

 great sluice at Denver, now in hand. It is worthy of remark, 

 that, as soon as the freshes were diverted from the old channel, 

 the warping action of the tides commenced ; and in six years' 

 time the mail coach passed over without a bridge, where any 

 frigate in His Majesty's service might once have floated. We 

 now come to the Sutton Wash ; being the last, and most diffi- 

 cult to execute, on account of its great width : but the experi- 

 ence gained in the two former cases has brought it to a per- 

 fect completion. In this case, likewise, the plan embraced 

 every thing possible ; and, whether considered as a drainage, 

 embankment, navigable outfall, system of warping, or means 

 of communication by its road and bridge, I venture to say that 

 there are few cases where they are all combined, with so little 

 injury to local interests. The line of communication is con- 

 tinued over Fosdyke, and over the Eau Brink Cut, and Old 

 Channel, near Lynn ; instead of the old mode of crossing by 

 fording and ferries. By these means, the distance by road 

 has been shortened near thirty miles between Lynn and Bos- 

 ton, and thereby a new direction has been given to the traffic 

 between the north of England and the county of Norfolk. I 

 may here remark, there are yet a few additions wanted to 

 make this line perfect ; for instance, between Fosdyke and 

 Boston four miles of the road are at this moment ungravelled ; 

 after leaving Boston, between three and four miles are lost in 

 crossing the south 40 ft. drain twice, though, by passing 

 through Swineshead, a road might be easily formed on the 

 north bank of the south 40 ft. A tremendous hill occurs near 

 Leadenham, about ten miles from Newark, which might be 

 easily avoided, at a reasonable expense; I do not know whether 

 it is a turnpike : if not, I should conceive it would answer to 

 be made one. Although I have introduced several subjects, 

 I trust you consider them as bearing upon, and elucidating, 

 the Sutton Wash. I am, Sir, yours, &c. — W. Thorold. Nor-

Our correspondent has obligingly sent us a map, showing 

 the situation of the banks, roads, and waters, described or re- 

 ferred to in his paper, but we regret that, from the space they 

 would require to render them at all intelligible, we cannot 

 find room for them. — Cond.
