HARKSTEAD,
The phosphate nodule bed
was also to be found in Harkstead where it outcropped
on the slopes and, from a geological article, there were at least four pits
opened but there was no indication as to ownership or when they were worked.
About three-quarters of a mile to the east of Harkstead
church is a small valley, and the ”coprolites• were
worked from beneath the crag on both sides. From map evidence, another pit was
marked further down this valley, just over half a mile south of Lower Houses,
near Burnthouse Queach and
this was in operation in 1881. The track nearby presumably led down to the
river where they would have been washed and loaded onto lighters bound for the
Ipswich manure works. (1881 25” OS map 89.1; Whitaker, ”Geology of Ipswich
Etc.•, 1885 p48. )
