LEIGHTON BUZZARD
The development of the nineteenth century coprolite industry in
this area of Buckinghamshire was based on the discovery of phosphatic nodules
in the Upper Greensand which were in huge demand for their conversion into
artificial manure. The earliest documented workings were in 1869 but it 1n 1871
when some of those living in Leighton Buzzard at the time may well have been
enticed into one of the many lectures that were given to the working people.
E.W. Lewis, a local teacher and fellow of the Royal Geological Society gave a
series of lectures on the geology of Leighton Buzzard in which he talked in
some detail about what he called clay pits which had been opened in the area
for their fossils.
”Regarded however from an
economical and commercial point of view they possess considerable interest and
value. At Henlow, Standbridge, Northall,
Slapton, Billington and Cheddington, at Stone and Dinton,
near Aylesbury, as well as at Brickhill and Ampthill these fossils have been
dug. Many tons are carted through our town every week, and some thirty or forty
thousand tons have been raised in this district during the past ten years. You
will now understand I am now referring to the Coprolites; or, as I once heard
them called, ”copperlites•; being solemnly assured at
the same time that they were dug for the copper they contained. In fact I
believe some persons thought they were productive of gold, which, however true
it might be in a more remote sense, was certainly no more true literally and
directly than the statement that they contained copper.
(E.W.Lewis. ”Lectures
on the Geology of Leighton Buzzard,” 1878-9,p48.)
The earliest contractors were two contractors from the Midlands,
Lee and Price who opened a pit near Cheddington, but
it was Henry Wilkerson a Cambridgeshire coprolite contractor who was
responsible for its early expansion on Earl Brownlow‘s estate in Ivinghoe and Slapton. After
running into financial difficulties with landowners in Cambridgeshire, he sold
his interests to two Wolverhampton manure merchants, Morris and
The work that went on in these pits was detailed by Lewis:-
”Transport yourselves, in
imagination, to a claypit whence coprolites are dug.
You observe a long straight trench, perhaps fifty yards in length, five or six
feet wide, and eight or nine feet deep, on one side of which is a vertical
”face of clay.”. The coprolites are not distributed throughout the clay; but
are found towards the base of the ”face,” where in a layer of varying thickness you find
them more or less thickly accumulated. This is the coprolite
”vein.”. The workmen throw the overlying clay to the opposite side of
the trench, till they come to the surface of the ”vein,•
the clay of which, thrown into trucks, is conveyed to the washing mill. Here it
is placed in a large circular iron pan, called the ”washing ring,” where by
means of water and a constant agitation the coprolites are thoroughly cleared
from the clay. In some veins, the presence of stones not coprolitic, such as
flints, pebbles, etc., makes it necessary to employ hand labour for their
removal. They are now ready for the market as the raw material, and in this
state are sent by rail or boat to the manufacturer, say, in this instance,
Wolverhampton.”

Having an office in Leighton Buzzard, Morris and
John Davey, a labourers in the employment
of Mr. Wilkerson, coprolite merchant of Leighton Buzzard, pleaded guilty to a
charge of being drunk while in charge of a horse and cart at Leighton Buzzard
on 17th January. His employer came forward and gave him an excellent general
character, stating that he believed he had been overtaken inadvertently in
parting with some friends who were bound for
He was fined 3s.6d. with 6s.6d. costs. Later that year the company started another works on
Earl Brownlow‘s estate further north on the Greensand Ridge just outside Great
Brickhill on Galley Lane Farm. These similarly were not far from the canal to
which a tramway was lain along horses would have pulled their coprolite laden
trucks down to the works near Stoke Hammond.
The early maps of this area show a considerable number of sand and
clay pits and there is every likelihood that they
developed at the same time as the coprolite industry when demand for building
materials was at its height with the expansion of many of the local towns and
industries.
