Exciting and unexpected archaeological discoveries show how no evaluation process for sites is fool proof. What happens next shows how important cooperation and communication is, particularly for the County Archaeology Service, who are tasked with supporting development AND safeguarding heritage. The critical concept is “significance” – how important are the remains; what is their potential to inform us about the past? Rachel Foster, Assistant County Archaeologist reports:
In 2017 Wessex Archaeology excavated a new housing development north of Bitham Park in Westbury. I had requested this work as a condition of planning permission, based on limited evaluation results. Unexpected discoveries demonstrated the challenges faced by Planning Archaeologists in understanding the significance of archaeological sites based on the results of trial trench evaluation.
The 2018 National Planning Policy Framework states that local planning authorities should identify and assess the particular significance of any “heritage asset” that may be affected by a proposal. In line with this advice, we often ask for sites to be investigated before the determination of a planning application, so that we have that information. Evaluation usually this consists of geophysical survey followed by trial trench evaluation. The Wiltshire and Swindon Historic Environment Record which contains detail on archaeological sites, buildings and finds, informs our decision making.
Archaeological evaluation can feel like a game of battleships. When geophysical survey goes well, and reveals features that look like potential archaeology, we ask for trenches to be dug and the features investigated by commercial archaeologists. The aim is to understand the significance of the site by investigating features within the trenches, which is not always so easy: if geophysical survey has not been carried out or is unsuccessful, then trenches are placed either systematically or randomly across a site and there is potential to miss remains. Today, the trenching is usually a 3-5% sample of the development site but in exceptional circumstances, up to 10% may be carried out. That sample of trenching should find archaeological remains within a site and provide enough information to understand the importance, extent and significance of any remains. Results of evaluation will then inform our advice to the planning officer on the impact of the development on archaeological remains. Remains considered to be of national significance are likely to be preserved in situ and not developed, but other remains are likely to be investigate. Early knowledge about archaeology and its potential effect helps the developers manage their risk and adequately budget for excavation costs, as well as post-excavation work and publication.
The geophysical survey results at Bitham Park didn’t show much other than a few lines representing ridge and furrow remains across parts of the site and a few other possible linear features. This image gives an example of the greyscale plot of the geophysical survey results (magnetromotry).
Geophysical survey isn’t always reliable, so I asked for trial trench evaluation prior to determination of the planning application: in some cases, later ridge and furrow can hide earlier remains. As the geophysical survey indicated, there were remains of medieval/post-medieval ridge and furrow cultivation; however, my assessment that there might be more archaeology was correct. Archaeological features were discovered across several trenches, mostly concentrated in the western part of the site. They included ditches, gullies and pits containing small, worn pottery fragments from the early/middle Iron Age and Romano-British periods (150BC onwards). Nevertheless, the significance and extent of the remains could not be fully understood, so I asked for a second stage of evaluation to provide more data. The extra information would help me define an area for archaeological mitigation – the full excavation of important features. The results confirmed prolonged and intensive agricultural use from the medieval period (1066- 1540). This had truncated and displaced features and artefacts from the earlier Iron Age and Romano-British periods; however, theses features included and arrangement of post holes representing a possible structure (see trench locations of two evaluation stages below).
On the basis of the two evaluations I asked for an area of excavation within the vicinty of where the most significant archaeological features were recorded, in the western part of the site and along a north-south trajectory.
In advance of the housing development an initial area was stripped with contingency and here’s an aerial view of the site below, can you spot anything interesting?
A new project recently appeared in the archive conservation lab: a brittle and damaged looking document that turned out to be an interesting new accession.
Letter Sent to Francis Yerbury, 14th May 1747 (1387/1697)
The document is a letter sent to local Clothier Francis Yerbury in 1747. It is thought that he may have run a cloth mill in Trowbridge although the letter is about a mill in Bradford-On-Avon. Hanne Dahl, Exhibitions and Collections Officer at Trowbridge Museum has transcribed the letter and below gives an overview of the its content:
The letter seems to consist of two messages. One is regarding a cloth order which John Howell has received and is ensuring Francis Yerbury he will pay for. The other is a new cloth order for the Empress of Russia of Clergy cloth in scarlets and greens. 5 cloth samples of Yerbury’s are attached to the letter as a colour reference. The Empress mentioned was probably Elizabeth of Russia who lived 1741-1762. According to popular history clothing was the chosen means in Elizabeth’s Court by which to display wealth and social standing and according to historian Mikhail Shcherbatov (1733-1790) her court was “arrayed in cloth of gold, her nobles satisfied with only the most luxurious garments, the most expensive foods, the rarest drinks, that largest number of servants and they applied this standard of lavishness to their dress as well.’ Hanne Dahl, Exhibitions and Collection Officer, Trowbridge Museum April 2019
The new accession was passed on to the archives here at WSHC by Hanne after being in the care of the Ponting family; the late Ken Ponting being former Managing Director of Samuel Salter Ltd. weaving mill in Trowbridge.
As is often the case with the documents I work on, there is much of historical interest and I could spend many hours researching them. However, as a conservator, once I have enough detail to inform my conservation decisions, I must tear myself away from the fascinating historical insight and prioritise stabilising and preserving the letter so that future researchers can access it safely.
It was originally folded to be posted and has the postal address visible on one of the folded sections. The letter is written in brown ink and has textile samples and a small part of a wax seal attached.
Several factors made this a conservation challenge; not only was the paper extremely thin and fragile but the additional attached textiles samples and seal remains also had to be considered at all times as they could easily become detached and lost.
The document needed to be packaged so that it could be safely stored in the archive but also handled without the risk of further damage. As the paper was so thin, it could easily tear again with further handling, even after conservation.
I decided that once repaired, the document would be safest inside a mount- this would allow for compensation of the thickness of the attached textile samples and seal remnants as the depth of the window mount would prevent them getting squashed or dislodged in storage. It would also enable easy viewing as and when required without direct handling of the letter. Text found on the back of the letter was all in one area so the mount could be adapted to have a viewing window on the reverse. This would also mean the document didn’t need to be taken out of the mount or handled to see this.
Areas of damage on the letter
The letter arrived with us inside a frame, attached to a backing board with tape partially holding it around some edges. The paper was so thin and weak that tears had started to appear along many of the original fold lines whilst large areas were breaking around the edges. It was important to remove the letter from the backing for several reasons; the backing board itself, made from poor quality board was likely to be causing damage to the paper. Unless they are archival quality, backing boards and framing materials are often made of very poor quality materials with high levels of acidity. As these materials break down they can transfer acidity to materials they are attached to, increasing their deterioration. I also needed to access the document to effectively repair the tears and remove the adhesive tape.
I was able to successfully remove the letter from the mount using a spatula to ease the tape away from the board surface.
When the board was removed it was possible to clearly see acid transfer which appeared to be coming from the document and transferring onto the backing board, suggesting the paper itself is acidic. This is likely to be due to the ingredients used when the paper was originally made, for example additives such as sizing and fillers or the materials the paper is made from such as wood pulp. The ingredients vary between paper mills and throughout the history of papermaking, for example Lignin from wood pulp is extremely acidic and is generally found in modern papers such as newsprint. This is what makes newsprint go yellow and brittle so quickly.
After removing the document from the backing a new area of writing was discovered where the letter had in fact continued overleaf. The archivist was then able to add this to the existing transcription.
Once the letter was separated from the backing board I could then remove the adhesive tape. This task of removing tape is always daunting for a conservator as different adhesives react completely differently to different types of removal. Sometimes it can take a long time to find a method that softens or releases the adhesive so that the tape can be removed.
On this occasion I found that applying moisture directly onto the tape was enough to release the adhesive. However, a thick piece of brown adhesive tape down the left side of the letter was so stubborn that after removing a small amount I decided it would be better to leave that particular piece of tape on rather than risking damage to the already fragile paper surface.
Once the tape had been removed I surface cleaned the document being careful to avoid any weak areas. I was then able to move on to repairing and stabilising.
Tears on paper documents are generally repaired by adhering small pieces of Japanese tissue to the reverse.
The tissue I used for the letter is only 5 gsm, so it is extremely thin and light- but strong enough to stabilise the tears and weak areas without distracting from the letter itself.
Two areas of the document had large gaps that although supported on the back with the Japanese tissue repairs, needed to be infilled with a paper of a similar thickness to the letter itself, to prepare the document for mounting. In the conservation of archival documents (as opposed to artworks) it is particularly important that repairs such as this are visible additions, clearly seen as modern repairs and not blended to make them invisible. This ensures that future historians and researchers are aware of the difference between the original document and any conservation work that has been done.
Creating an Inlay
In paper conservation an inlay is a piece of paper that is attached around the outside of the document to protect it and prevent further damage to fragile edges. This is achieved by tracing around the edge of the document using a needle and then removing the inner piece of inlay paper to create a paper frame. The inlay paper is attached to the document by thin strips of Japanese tissue adhered along the gap between the two. The inlay protects the original document whilst still retaining full visual access to it. It also means that the document can be attached inside the mount by putting hinges on the inlay paper rather than directly on the document itself and that the letter can be fully displayed in the aperture of the window mount without falling out through the middle.
16 August 2019 marks the 200th anniversary of the 1819 Peterloo Massacre where 60,000 people demonstrated in St Peter’s Field, Manchester demanding parliamentary reform. Eighteen people were killed and hundreds injured when the Manchester and Salford Yeomanry and the 15th Hussars were sent in to disperse the crowd and arrest the leaders.
Politician, Henry ‘Orator’ Hunt, a principal speaker at the St Peter’s Field meeting, was born at Widdington Farm in Upavon, Wiltshire on 6 Nov 1773.
Hunt was educated at Tilshead on Salisbury Plain by a Mr Cooper and later in Hampshire. In his memoirs Hunt recounts he was ‘sent to boarding school at Tilshead in Wiltshire, at five and a half years of age… This school, which was situated in a healthy village upon Salisbury Plain, consisted of a master and an usher, who had the care and instruction of sixty-three boys. The scholars were better fed than taught’.
Although his father hoped he would go into Holy Orders, he was inclined towards farming, and began work on the farm aged 16. His experience of the local poverty and rural administration is what has been posited as the driver towards his radical views.
He married a Miss Halcomb, daughter of the innkeeper of the Bear Inn, Devizes and had two sons and a daughter, but the couple separated in 1802, and he eloped with a friend’s wife, Mrs Vince.
He farmed at various locations in Wiltshire, Sussex and Shropshire, and became involved in politics and became a noted public speaker. His rousing speeches at the mass meetings held at Spa Fields, London gained him his ‘Orator’ nickname.
He was invited by the Patriotic Union Society to be one of the key speakers at the scheduled meeting in Manchester on 16 August 1819.
One of the many joys of our archive is how it encompasses not only the county’s history – its people and places – but also world events as witnessed and experienced by Wiltshire folk through the centuries.
Each year I am in the privileged position of being able to take young historians on an archival journey round the world thanks to the extensive collections held by Wiltshire and Swindon Archive. These youngsters come to the Wiltshire and Swindon History Centre for work experience and for a week they get to explore the archive and local studies collections, as well as learn about the work of the conservators, archaeologists, civil registration certificates team and business support staff.
During five weeks of work placements – this year we took 14 students from six schools –the archives have transported us through time and space. We have crossed continents and centuries, catching a glimpse of the ordinary and extraordinary lives of people from another time.
As Education Officer at the History Centre there are types of documents that I frequently use because they make great classroom resources – maps, photographs, diaries, personal letters, school log books. And then there are the topics for which we have excellent collections – Tudors, Victorians, canals and railways, the First and Second World Wars and the Cold War.
But with the arrival of work experience students I have the opportunity to explore the archives at a more leisurely pace and in broader terms – and I am always finding new things to look at or seeing familiar documents in a different way. A good example is Siegfried Sassoon’s February 1933 letter predicting war. This year was the third time I produced the document for students and it was as they were practicing their transcribing skills I finally made out a word that had been eluding me all this time – ‘entente’. It was so obvious that I’m slightly embarrassed to admit that I had not worked it out sooner.
Although we often begin by digging out documents related to topics being studied at GCSE and A-Level, the challenge is to find the more unusual and quirky among them that don’t always see the light of day but which take us on wonderfully unexpected journeys.
One of the quirkiest set we produced this year concerned the gift of an elephant to Queen Charlotte (wife of George III) in 1794. Three letters (WSA 9/34/42) contain hints and allegations of an East India Company man, who acted as an intermediary in delivering the elephant, claiming back the cost of the animal despite it being a gift.
The East India Company is well documented across a number of significant collections within the Wiltshire and Swindon Archive, including archives from Wilton House, the Earls of Radnor (Longford Castle), the Seymour family (Dukes of Somerset), politician Walter Hume Long and the Money-Kyrle family.
But I was not expecting to find any further reference to elephants… Yet in the Lacock archive, among documents belonging to the Davenport family, is a cache of letters, invoices, receipts and company accounts detailing goods being shipped – including elephants’ teeth! (WSA 2664/3/2B/125 & 139 and WSA 2664/3/2D/79 et al.)
Wiltshire Buildings Record held its 40th AGM in Bratton on the 22nd June. The weather was beautiful and a miraculous interlude in a succession of grey, stuffy days that had come before. After the business meeting Mike Manson of the Bratton History Association gave us a Powerpoint presentation on the origins and development of Bratton, which was apparently once three separate settlements. The wealth of fine houses hidden down picturesque lanes were derived from the woollen industry in the 17th and 18th centuries. West Wiltshire was dominated by a small group of entrepreneurs who controlled the woollen industry as landholders, buyers and employers. The most prominent family in Bratton and Westbury was the Whitakers; wool merchants whose impressive home was the Courthouse in Court Lane, dating from the medieval period and onwards. Iron replaced wool in the 19th century, as Dennis Gardner, another BHA member explained in a separate presentation. Reeves ironworks produced agricultural machinery and was the largest employer in Bratton until the early 20th century. We went out, fuelled by much cake and tea, down a positive rabbit-warren of unexpected leafy lanes, guided by Mike. Owners of houses were moved to come out and investigate at the sight of a large bunch of strangers all staring steadily in their direction. All were friendly though, and a mine of information. Much of the timber-framing we saw appeared to be 17th century, or 17th century improvements of earlier buildings which in at least two cases included a chute at the front, possibly to load fleeces directly into a wool loft at the top of a house (as found in a WBR recording of Court Lane farmhouse a few years back). There was much speculation over this, with the conclusion that many villages had their own peculiarity in building which was influenced by the prevailing economic activity, in Bratton’s case, its woollen industry in the 17th century and possibly later. As usual though, more research is needed to prove this link.

Having reached the milestone of 10 years in my current place of work, I have been reflecting on the development of my career. I think my greatest fear as a conservator is stagnation: for my work to have lost its vibrancy and draw, for my relationship with my career to have become stale.
Thankfully, even after a decade I still find daily challenges and opportunities to develop and thrive within the sector. The importance of Continuing Professional Development (CPD) is emphasised within the conservation arena; viewed as integral to the maintenance of professional standards by organisations such as ICON, the Institute of Conservation.
Being an accredited conservator (ACR), maintaining CPD is essential to retaining my accredited status.
The CPD format encouraged by ICON allows conservators to reflect on where they have come from, focusing their aims for the future. Through a candid analysis of the strengths and weaknesses within both my team and my own armoury I was able to identify a need to improve specialist knowledge of the care of natural history specimens.
The generous award of a True Vue professional development grant allowed me to secure a place on an intensive 3 day course focusing on the care and conservation of vertebrate taxidermy specimens with Simon Moore, a subject specialist with 50 years experience.
The 3 day course kindly hosted by Reading Museum allowed experience of a broad range of materials and techniques. From the art of opening historic glazed cases, without which you’d never access the specimens; to the cleaning of feathers, repair and replication of birds toes and the creation of hair plugs for a balding otter!
The course created a relaxed welcoming environment in which I felt able to voice my previous anxieties about tackling such materials from the risk of shattering historic glass to fears of using the wrong materials and my work ending in a terrible taxidermy publication!
The natural history collection at Reading Museum is extensive and allowed course attendees the irreplaceable opportunity to put theory into practice.
