TRIMLEY,
SUFFOLK
Although
the coprolite diggings started in the area around Felixstow in about 1845 there
has been no evidence of the work extending into the parishes of Trimley St. Martin or Trimley St.
Mary until the 1880s. There had been men employed as stone dredgers, going out
into the estuary to dredge septaria, nodules of clay,
which was used in the manufacture of Roman Cement but the phosphatic nodules
would probably have been exposed in crag pits in a seam between the overlying
Red Crag and the London Clay. No documentation has emerged to show they were
exploited by local landowners but the earliest reference to the diggings in
this area was in the early 1870s when a number of coprolite pits were reported
as in operation. A geological account of the area referred to
a newly opened coprolite working in 1874, "at the top end of the little
wood about a mile northwest of Trimley churches, and
close to the railway." The overlying Crag was from four to six feet
thick and as the phosphate bed was up to three feet thick it would have been a
very profitable venture, especially being so close to the railway. The same
seam was also worked in a pit, "at the back of a cottage about three
quarters of a mile westnorthwest of the
churches," and also just to the northeast and southeast but it was only
six inches thick here below cover of up to seven feet.
The
18.. map of the area showed a
number of crag pits, the largest being Hanging Crag Pit just east of Loompit Grove. "Round Grimston
Hall, half a mile west of Trimley,
coprolites have been largely worked," yet in 1874 there were four
workings in which the seam was exposed. The first, between seven and nine feet
deep was just southwest of the house, the second, up to sixteen feet deep, was,
"a little north of the farm, on the western side of the lane to Trimley." A third, six feet deep, was on the opposite
side of the lane and a little to the south and the fourth "in full
work," just northeast of the Farm was about twenty two feet deep. A little
to the southeast close to Fagbury Cliff the bed was
worked again. (Whitaker, "Geology of Ipswich Etc." 1885,pp.52-3)

MAPS
Interestingly,
when the 25" map was first published in 1881 there were still two
"coprolite pits" in operation in Trimley
St. Martin a quarter of a mile north of Aleston Hall
at the end of Common Lane. (25" 1881 map 83.15) There were also two more
crag pits near Milford Cottage half a mile east northeast of Trimley. As no records of agreements have come to light
there is the strong possibility the landowner at the time arranged for them to
be raised and sold them to the manure manufacturers.
The
1881 census revealed that there were only five men involved, all locals living
on Lower Street, Trimley St. Martin, with Daniel
Brown the eldest at 40 and Henry Collins the youngest at 22. Their average age
was 31, showing that it tended to be the work of older men, as many of the
younger men during the period of the agricultural depression had left the
countryside to find work in the towns. However, according the to the trade
directory for 1885 it was,
"a department of industry which is now employing a good deal
of capital as well as labour... There are extensive beds of coprolites in
Suffolk, chiefly at Kirton, Trimley,
Felixstowe, Bawdsey, Alderton
and other places in the Colneis and Witchford Hundreds... Immense quantities are raised in Colnei Hundred. Whole fields have been regularly turned
over, sometimes to the depth of 30 or 40 feet. It is usually undertaken by the
tenant, who pays a royalty to the landlord of so much per ton. The work is
carried on with more or less vigour, according to the season when labour is
scarce or plentiful. The surface soil is carefully preserved at top, so that
the land from which the coprolite has been taken is not materially damaged. The
tenant sells and carts to the nearest town or wharf at such times as his horses
are most at liberty. The depression in agriculture has caused a corresponding
slackness in the manufacture of artificial manures and the raw material which
the coprolite furnishes has not now a very ready sale."

Directory,1885)
