NHER 17840 (Monument record) - Wooden water pipes

January 1982. In river bank opposite Coltishall Hall.
Wooden pipes, probably for drainage, uncovered in cutting moorings.
(S1) shows 4 tree trunks, 3 of which have their interiors hollowed out to form pipes.
All are cut to a polygonal shape on exterior.
2 are cut down at end as if to fit inside another.
The third has a rectangular end.
Suggested as drainage pipes from Hall.
Unknown date.

(S1) suggest these are wooden pump shafts from wells and give parallel examples.
Probably dumped in river subsequently, or for seasoning.

The 3 pipes are now used as seats on the green here and do appear to be pump shafts.
E. Rose (NAU), 25 May 1983.

But they have gone by April 1985.
