Goathland Incline: a Community Archaeology Dig

Maria-Elena Calderón – This Exploited Land of Iron Cultural Heritage Officer and David Mennear – This Exploited Land of Iron Administration Assistant

Introduction 

This Exploited Land of Iron, our HLF Landscape Partnership Scheme, has had a busy and successful first summer with well attended events and exciting activities taking place across the North York Moors. This Exploited Land of Iron is investigating the once booming ironstone industry, which spread across the area from the early 19th century until the mid-20th century, although you may not easily notice its intrusion on the beautiful landscape today.

Following our first archaeological dig at Combs Wood (Beck Hole) back in May, our second archaeological excavation recently took place at the Goathland Incline over a two week period between 25 July and 5 August. It proved particularly popular with volunteers and passing visitors.

Today the village of Goathland is a peaceful and idyllic haven for tourists, a former spa town famous for the North Yorkshire Moors Railway and for masquerading as the fictional village of ‘Aidensfield’ from the old TV series, Heartbeat. You wouldn’t know today to look around the village, but Goathland once played a brief but fundamental part in the 19th century ironstone mining industry, a noisy and disfiguring industry that required the transport of thousands of tonnes of ironstone across the North York Moors via railways. In fact not many historic photographs of the Goathland Incline survive at all. As such we didn’t quite know what existed or what remained. Targeted archaeological excavation, following a thorough study of the area and its history beforehand, was undertaken to investigate the remains at the Incline..

Goathland Incline: A Brief History of a Modern Mystery

The site itself dates to a brief period in the mid-19th century when the railway was in its infancy. The early Whitby to Pickering horse-drawn railway was designed in the 1830s by none other than George Stephenson, the famous and much in-demand ‘Father of the Railways’. For the majority of the line, wagons and carriages were hauled using horse power; however, due to the 1 in 5 gradient present between Beck Hole and Goathland, an alternative power source was required. Powered inclines had been in use for a number of years by this point, employed primarily at mines. At Goathland a gravity system was used to haul the wagons and carriages up the incline – water butts were filled at the top of the incline and their weight was used to offset the weight of the wagons themselves, effectively and somewhat spectacularly pulling them up the incline. Once the water butts were at the base of the incline, they could then be emptied and brought back up by horses to be used again.

In 1845 the horse-drawn railway was transformed into a steam hauled railway by the new owner, a certain Mr George Hudson. At some point the incline itself was also transformed to steam power with a stationary engine sitting at the top of the incline. The engine house is shown on the Ordnance Survey map surveyed in 1849, but we’re currently unsure of the exact year that this new feature was installed. The conversion to steam power also required the installation of turntables at both the top and foot of the incline itself, as unlike the horses, locomotives could not turn themselves around in such a small space.

The incline was a perilous operation and was known to fail; a crash in 1864 killed 2 people and injured 13. In 1865 a deviation line was built which took a wider route with a shallower gradient that eliminated the need for an incline. The buildings were demolished, the site was abandoned to be subsumed back into Goathland village and the rest, as they say, is history.

The Dig Itself

Due to the early date of the railway at Goathland a lot of the layout relating to the gravity system remains unknown as it was replaced before the earliest ordnance survey maps. So we decided to open a series of trenches that targeted known historical structures and possible new structures identified by a LiDAR survey. Using remote sensing LiDAR maps the topography of the land from above and because it takes measurements from a variety of angles, it can effectively see though heavy vegetation and wooded areas. This allows for the identification of possible building structures or man-made earthworks within the targeted area.

Light Detection and Ranging, otherwise known as LiDAR, is a remote sensing method used in archaeology to examine the landscape surface. Here you can see the representation of the land around the historic site of the Goathland Incline, including a suspected turntable.The purple circle is the turntable and the blue rectangles the main trenches targeted within the red study areas

We placed three trenches over a circular feature suspected to be a turntable, one over a series of linear features shown in LiDAR and thought to be the remains of buildings, and one over the alleged engine house for the stationary engine.

The engine house location proved true but unfortunately not the rest. In archaeology, with both the best will and research in the world, you never truly know what you are going to uncover. The turntable was in fact a reservoir and what looked like building remains were probably instead the remains of allotment beds.

Our amazing volunteers hard at work on the trench that provided to be a bit of a damp squib.

The reservoir was interesting in itself as it turned out to be a clay capped earthen structure that had silted up over the years and had obviously been used as a rubbish dump. Finds such as jars, broken toys, Victorian glass bottles and ceramic wares gave us an insight into 1860-1940s Goathland life. Despite the late nature of the finds themselves, the structure itself we believe dates from the early gravity system, and offers us the only archaeological insight into that period. At that geographic level in Goathland there is no fast flowing water supply sufficient enough to fill the water butts for the gravity-assisted incline system. As such large water storage areas would have been required and allowed to fill on a slow trickle. Could this be what the reservoir was used for?

Getting down and dirty investigating one of the trenches with our Cultural Heritage Officer Maria Calderón and placement student Ewan Chipping to see what great work the volunteers have done.

Within the trench targeting the engine house we found substantial remains of stone walls 70-80cm (28-32”) thick with foundations continuing below a 1.4m (4’ 8”) depth from the surface level. It is clear that the engine house was a substantial structure with a basement. There were two internal rooms divided by a further stone wall. The building would have been roofed in slate, rather than the local vernacular of pantile; this is typical of railway buildings, as the companies that operated the railways worked on a regional or national level, and did not respect local building traditions.  Sadly we found no evidence of conduits or the stationary engine. In all likelihood most of the metal worked was instead probably sold for scrap at some point. To the north of the building we found traces of a stone covered yard.

‘Have you found anything interesting?’ We certainly did! You can tell by the foundations of the stone walls in this trench that a substantial building once stood here, like the engine house.

Goathland Uncovered: Mystery Solved?

But we had not given up on the turntable and with the help of a local resident we gained permission to open further excavations on the site. We opened six small test pits and hit the remains of a turntable in three pieces; two edges and at the centre point, from which we can extrapolate the size. This was a highlight of the excavation and was the fruitful work of a few very determined volunteers. One of the smaller test pits also identified the corner of a brick building that had been demolished.

A successful dig then, but questions still remain regarding the Goathland incline site:

a) How deep does the engine house go?
b) Are there any remains in the rooms waiting to be discovered?
c) Where was the cable drum for the incline?
d) What is the small brick building?

With these questions lingering in our minds after the excavation we’ll now process the information recorded and help to produce archaeological reports based on the available evidence. As always with archaeological fieldwork there may be more questions than answers, but what this dig helped uncover is invaluable to learning about the industrial life of the Goathland Incline and the individuals who worked on it and lived nearby.

Last but not least, we also had time to celebrate Yorkshire Day on the 1st August with a good mug of Yorkshire Tea!

In amongst the digging we also managed to make a short film (in very windy conditions) – have a look here.

We would like to extend a big thank you to all of our volunteers who took part in the excavation, and also a big thank you to all of the members of the local community who came to visit us and asked great questions or provided invaluable insights into Goathland life and industry.

Lest we forget

Beth Davies – Building Conservation Officer

A hundred years ago the First World War was into its fourth calendar year with no end in sight; Germany announced on 31 January 1917 that unrestricted submarine warfare would commence the following day and all ships in the war zone would become targets…

It is very difficult for us now to appreciate the full horror of what the servicemen who fought in the war experienced. Similarly we can only begin to imagine what it must have been like for those at home left behind without fathers, husbands, brothers and sons.

In the aftermath of the First World War thousands of built memorials to the dead were erected across Britain. These communal memorials acted as shared totems for society suffering devastating loss and in the face of the official policy of not repatriating the dead. They provided an embodiment of the common grief felt and the validation of sacrifice, and still today provide a tangible reminder of the real impact of war. Whereas the huge numbers of dead and injured are difficult to grasp, the individual names of the local people lost are poignant and tangible.

War Memorials draw particular public interest and warrant serious consideration for listing. Historic England is particularly keen during the centenary of the First World War to increase protection of unlisted memorials. Following on from the listing of the Commondale Shepherds’ Memorial last year, we are pleased that two further war memorials in the North York Moors have been afforded Grade II listed status as part Historic England’s drive to protect for posterity these meaningful and evocative structures.

Glaisdale War Memorial. Copyright Mel Gibbs.Glaisdale War Memorial was unveiled on 4 December 1920 by Major General Sir James K Trotter, FCB, CMG. It is an elegant example of a Latin cross set on a tapering octagonal section shaft and displays a high level of craftsmanship with carved decorative details and fine lettering. Its prominent location on a small green with expansive views north down Glaisdale contributes to its impact in recalling the memory of the dead and where they belonged. The plinth at the base of the shaft reads ‘TO THE MEMORY OF THE MEN OF GLAISDALE WHO FELL IN THE GREAT WAR 1914-1919 JESU BLEST GRANT THEM IN THY LOVE TO REST’. There are thirteen names: John Boas, William J M Child, James Jefferson, John Pearson, Ralph Scarth, Charles E Scanlon, John H Scarth, Frederick Scarth, Francis R Scarth, William Ward, Ernest Wilson, Pennock Winspear, Harry Winspear.

The Commondale War Memorial was unveiled by Lord Guisborough at an ecumenical ceremony held on 31 August 1921. It was designed by WH Earl of Danby and made by J Ford of Castleton. The memorial commemorates nine local servicemen who died during the First World War including the two shepherds commemorated by the aforementioned Grade II listed Shepherds’ Memorial.  The names are Thomas Monk, Samuel Lawson, Thomas Gibson, Robert H Leggott, William Hill, Frederick W Robinson, Charles E Foster, Alfred Cockerill, David Johnson. It comprises a stone Latin cross on a short Commondale War Memorial. Copyright Hidden Teesside.tapering square-sectioned shaft which rises from a plinth set on a four-stage square base. Set into the plinth are unusual, brown salt-glazed stoneware tablets probably made by the local London and Cleveland Fire Brick Co Ltd Brick and Pipe Works. On the main facing and rear tablets are stamped the words ‘IN HONOURED MEMORY OF THE MEN OF COMMONDALE WHO GAVE THEIR LIVES FOR GOD, KING AND COUNTRY, IN THE GREAT WAR 1914-1918. THEIR NAME SHALL LIVE FOR EVER AND THEIR GLORY SHALL NOT BE BLOTTED OUT. LEST WE FORGET’.

Revitalising the Rye

Tom Stephenson, External Funding Officer

There must be something in the water in the North York Moors, having just started delivering the This Exploited Land of Iron Landscape Partnership Scheme, the National Park Authority and its partners* have also been successful at the first stage of securing a further £2 million of Heritage Lottery Fund money to develop our next Landscape Partnership SchemeRyevitalise.

The River Rye and its tributaries rise on the moorland of the North York Moors, flowing through fast and clear upland becks that carve out steep sided dales until the land flattens and the river slows and broadens taking on the character of the undulating Howardian Hills and the flat lowlands of the Vale of Pickering. The Ryevitalise Landscape Partnership Scheme under development will help appreciate and enhance the Rye’s verdant landscape and clear waters which have been prized for millennia for their beauty and tranquillity resulting in a more natural, better functioning and better understood landscape.

Planned projects will cover four themes:

  • Water Environment, looking at aquatic habitats of the Rye and rare and threatened species;
  • Water Quality, working with land-owners and managers to reduce pollution;
  • Water Level Management, working alongside our delivery partners to harness natural processes to manage the sources and pathways of flood waters; and
  • Reconnecting People, improving the understanding of the river landscape by telling the story of its evolution and helping people to protect their heritage.

Without wanting to spoil the surprise of future blog posts, below are just some of the particular issues we are aiming to address through Ryevitalise scheme projects if we’re lucky enough to be successful in our Stage 2 application due in October 2018.

The wet…

Water is the major theme of Ryevitalise. Through the Ryevitalise scheme, from the high moorlands to the lowland wetlands, we will identify priority areas of riparian habitat for restoration to ensure existing high-value habitats (and their species) are in positive management and can act as nodes from which to extend outwards by creating ‘stepping stones’ and connections between these habitat sites.

Wetter still, we will assess the geomorphology and key features of the aquatic environment and target areas where aquatic habitats could be improved by creating changes to the channel through creating gravel bars, by placing debris to create slacks or by making changes to river bank profile. This work will include a survey of the habitats and species of the oxbow lakes in the lower Rye, and also the collecting and analysis of sediment cores to look for valuable paleoecological data which might shed light on how the local landscape formed.

The dry…

in Duncombe Park has on the White-clawed crayfish, the only native crayfish in the UK, White-clawed crayfish - during 2016 rescue in Duncombe Park. Copyright NYMNPA.which is suffering from a “perfect storm” of threats. Ryevitalise will prioritise protective measures for the existing population and carry out a feasibility study to identify where potential local ark sites might be located. Ark sites for White-clawed crayfish would allow populations to become established in isolation, separated from the threat of non-native crayfish and the crayfish plague they can carry.

The small…

Relatively new to science, having been first identified in 2001 and only recently becoming the latest addition to the UK bat family, this little creature has only been found at two other sites in the UK so far. Ryevitalise will seek to establish a deeper knowledge of where colonies of the Alcathoe bat and other key bat populations are, along with the requirements to support their survival.

The tall…

At the other end of the size spectrum and intrinsically linked to bats are some of the Rye catchment’s largest residents – its ancient and veteran trees. The area is a national hotspot for these giants that not only give an air of majesty to the landscape as living witnesses to history but also provide important habitat for many invertebrate species as well as providing important roosting sites for Rye bat populations.

The old…

Not only is the Rye catchment home to iconic built heritage like Rievaulx Abbey, Rievaulx Terrace, Duncombe Park and Nunnington Hall but it also contains a wealth of less obvious heritage that traces vernacular land use and tells the story of the working River Rye. Working with local history groups, Ryevitalise will record the remaining evidence of man’s relationship with the river over the centuries, surveying and recording the traces of the former agricultural and industrial settlements along the river banks. Accurate 3D models will be produced of the principal remaining watermills, iron working sites, water races and leats. Essential conservation and consolidation work will be identified from the surveys carried out.

The new…

Copyright North East Yorkshire Ecological Data Centre.Like a lot of watercourses, it is not practical to access the river in its entirety at ground level. So as part of the Ryevitalise scheme an Unmanned Aerial Vehicle flight will record the entire 50km main river from its moorland origins all the way downstream to where it
meets the River Derwent. This will produce an invaluable record and will provide an insightful journey along the river for local communities, highlighting how this vital artery connects them all. Tailored sections of flight data will be made freely available to local schools, businesses, and community groups as a community resource; it will also form part of the scheme’s wider education programme.

We are all really excited about the next steps in developing the Ryevitalise scheme; the opportunity to make the most of the wealth of habitats, species and history surrounding the river; the potential to make a lasting difference to this wonderful landscape, and the chance to create a real splash.

2.Historic Pub Culture

As part of the renovation of The Crown Hotel in Helmsley the building was subject to a re-assessment of the development of its historic fabric by Colin Briden, an Historic Buildings Archaeologist who reported in April 2016. His report concluded…

Although partly demolished in the 18th century to bring it ‘up to date’, and extensively refurbished in the 20th century to make it look ‘olde worlde’, the building retains considerable evidence for a high-status late mediaeval timber framed house of two jettied storeys (where upper storeys project beyond the lower storey) and attics in a prominent position. The house is of an unusually large scale. Other comparable size houses in the wider area are from much later dates.

Now that the building is free from the unfortunate results of the 20th century remodelling it is possible to see it as it really is – ‘the battered remnant of late mediaeval construction work on the grand scale carried out by an unusually wealthy owner’.

In 1478 Helmsley was sold to Richard, Duke of Gloucester, later Richard III; it reverted to the de Roos family on his death. The name of the subsequent hotel is suggestive of a reference to this short lived but significant royal ownership.

In its latest adaptation, the building is now a shop.

5.Cliff edge archaeology

Following our work in 2014-15 (reported in early 2016), we were pleased that Historic England were able to remove one of the coastal alum working Scheduled Monuments from the Heritage at Risk register because we had fully recorded those parts of the monument which were under threat. However, four other Scheduled alum working sites remain on Historic England’s Heritage at Risk Register despite our efforts to record some of their most vulnerable features. So what next?

Working with Whitby Museum and specialists from Historic England, we held a seminar last spring bringing together a group of dedicated people with a strong interest or connection to the coastal alum working sites – landowners, archaeologists, academics and private researchers – to review what we know about the alum industry, to decide what we don’t understand and to look for a way forward to manage the risk to the sites under threat and ensure that we do not lose the valuable information held within them. One of the ideas emerging from the seminar was a further excavation project with an emphasis on engagement and interpretation as well as research.

Archaeological excavations take considerable planning and funds to ensure that they are carried out to a high standard and achieve objectives without causing accidental damage, so it can be a slow process getting started. We are now working towards setting up a project to investigate one of the sites which we didn’t include in the investigations in 2014-15 – the alum works at Stoupe Brow, near Ravenscar. An extensive system of reservoirs and water leats (dug channels) was revealed on the nearby Fylingdales Moor after the 2003 wildfire and we know that this water management system supplied the needs of the alum processing at Stoupe Brow, but other than that we currently know very little about this site. Historic England recently completed a topographic survey of the earthworks so we can now see how the site was laid out, but not how it operated. The site still includes its alum house (where the final processing to produce alum crystals was carried out) and there is still a general gap in knowledge when it comes to how alum houses functioned. As well as trying to discover more about the practical operations at the site the project will record the structures which are currently being gradually lost over the cliff edge. A big advantage of this particular site is that it is more accessible and less dangerous compared to some of the other coastal alum working sites – providing great opportunities for volunteers and visitors.

The first stage of the project is producing a project proposal which will outline what we want to do and how much it will cost, and this is expected by the end of this winter. The next step will be using the proposal to generate partnership support and seek funding. It is early days yet, but we hope this will develop into an exciting project – watch out for further posts as our plans progress.

Sounding like Christmas

Clair Shields – Planning Policy Officer/Building Conservation Officer

Now that the lights are twinkling and the decorations are up, everywhere you look it is all about Christmas. So with this thought in mind I was intrigued as to what festive sounding names the built environment can offer at this time of year. Below are a few Christmassy sounding historic features found around the North York Moors

Christmas Tree Field, Jingleby – This is a double hit of a Christmas sounding site within Dalby Forest. The archaeology of the wider area is significant and complex. The area includes Bronze Age round barrows, and a number of embanked pit alignments (prehistoric linear boundary earthworks) as well as later banked field boundaries which might be connected with rabbit warrening. There is also documentary record of a Jenglebee Cross but its exact location isn’t known.

Goose I’ Th’ Nest is one of a row of nine boundary stones on Wheeldale Moor, described as a natural boulder or deeply buried slab with letters ‘PCE’ and an illegible date.  Good Goose Thorn is another boundary stone, possibly of medieval origin, located on the parish boundary between Loftus and Glaisdale. Its specific name is recorded on the
Example of a boundary stone on the North York Moors.1st edition 6 inch Ordnance Survey Map of 1853

Although these particular boundary stones are not Listed or Scheduled, there are many that are. Boundary stones identify the start of a land boundary or the change in a boundary, especially a change in direction, and are a feature of the North York Moors. They are often marked on the most relevant face with the landowner’s or parish initials to indicate the ownership. Like waymarker stones they would have been important features for people having to cross the moors, defining the route to follow in a landscape which has very few points of reference.

There are a number of features called Stocking – Stocking Craggs, Stocking Dike,
Stocking House, WesterdaleStocking Lane and Stocking Hill. There are a couple of Stocking Houses – this Stocking House, to the north-west of Westerdale, is a group of unlisted buildings. Although not listed, together these buildings are typical of a traditional North York Moors moorland farmstead – small in scale, linear in form and of stone and pantile construction.

Frost Hall in Farndale is a farmstead with a range of listed farm buildings and a listed
farmhouse dated 1826. The range includes a threshing barn with a horse engine house Frost Hall, Farndale(for horse powered machinery) attached to the rear. Close by the farmstead there are a number of staddle stones (arranged to lift structures like granaries or haystacks off the ground), the remains of a saw pit (in which to operate a two handed vertical saw for timber) and also a chambered sheep fold which has been used to hold bee hives.

Holly Cottage, Holly Lodge, Holly House – there are plenty of Listed Buildings with this name, presumably there had been a holly tree nearby or otherwise the name sometimes
derives from the word ‘holy’. This one is Holly Cottage in Lythe, a characterful Grade II
eighteenth century house. This building is a good example of how a building has evolved Holly Cottage, Lytheover the years – probably originally a traditional longhouse it has clearly been raised at some point in its history and also extended. The variation in windows style, sizes and their location on this elevation all add to its unique character and adds to its special interest and architectural character and is typical example of the North York Moors vernacular.

Merry Christmas and a Happy New Year from the North York Moors National Park

End of an era

Our Senior Archaeologist is taking phased retirement, so before he goes he has been asked to reflect on his time with the North York Moors National Park.

Graham Lee – Senior Archaeological Conservation Officer

graham-leeHow do I sum up a career lasting over a quarter of a century in a few paragraphs? It is a strange feeling to have 26 years seemingly flash by so fast.

I started work for the North York Moors National Park in April 1990, having previously worked in the archaeology section of North Yorkshire County Council since the summer of 1983. I had decided many years before that I loved the north of England and had no desire to return to my southern ‘roots’.

Graham had decided many years before that he loved the north of England, whatever the weather ... Copyright - NYMNPA.One of my first tasks with the National Park was the completion of a management survey of one of our large estates, encompassing moorland and large blocks of forestry. This quickly whetted my appetite for the excitement of making new archaeological discoveries – often very subtle earthworks, no more than a handful of centimetres in depth or relief – despite an exceptional tradition of previous high quality archaeological fieldwork in the region. Working solo in large blocks of conifers was a good test of dedication – crawling under the branches of dense stands of conifers searching for vague earthworks mapped in the 1890s – and the steadiness of nerve, when yet another wretched pheasant exploded out of the leafy vegetation where I was just about to step! In recent years the delights of discovery have been broadening thanks to new technology and techniques, especially LiDAR which provides an aerial view through tree and ground-cover vegetation of archaeological remains that were previously hidden or obscured.

If you have a passion for the past, the North York Moors have something for pretty much everyone – enigmatic Neolithic rock art; surviving prehistoric pitted boundaries and avenues; upstanding Bronze Age funerary monuments and field systems; Roman encampments; medieval castles and monasteries…

Human industry is also well represented – from the earliest iron industry through the search for alum into the full-blown “iron rush” of the mid 19th century, the exploitation of coal and jet, and the plentiful local rivers managed to provide motive power for a range of watermills. Research and conservation priorities relating to these local industries finally led to our new HLF Landscape Partnership Scheme, This Exploited Land of Iron. Some 15 or so years in gestation, it is very rewarding to see new generations captured by the excitement of the important remains of our 19th century ironstone industry and the associated development of early railways – although the original scheme for a canal link between Whitby and Pickering would have been a sight to behold and a major tourist attraction if it had ever been built.

Into the 20th century, remains survive here from both world wars – in the form of coastal defences, army camps as well as troop training and target practice areas. Finds are still occasionally made of 2nd World War unexploded ordnance in former training areas across the North York Moors, in particular after the wildfire on Fylingdales Moor in 2003 which affected two square kilometres of heather moorland.

Although an environmental disaster – the severity of the fire in reducing the shallow peat cover to ash, this event was an archaeological revelation. Virtually everywhere you looked, subtle archaeological remains became visible, including the drip gulleys around former prehistoric round houses, low stony prehistoric boundaries and cairns, large numbers of previously unrecorded examples of Neolithic rock art and occasional shallow trenches which resembled grave cuts with a subsiding infill. As numbers of the latter quickly increased their interpretation became clear – slit trenches from 2nd World War troop training. I remember my first visit to the site after the fire when the ground was reddened and blackened, covered in ash and still smouldering; few trees had survived and many had toppled after the peat holding their roots in place had been burnt away. Flashes of colour were very noticeable, such as an adder emerging from its underground refuge having survived the conflagration. A major project ensued, both to protect and restore the moorland habitat and to record and investigate the breath-taking remains of surviving archaeology.

A visit to the Scheduled Rosedale iron calcining kilns with the Park’s Conservation Director at the time revealed that a portion of one of the kilns’ firebrick linings had collapsed the previous winter. This led to a major conservation project to stabilise these huge monuments which ran for three years in the mid 1990s, a forerunner of This Exploited Land which will continue the efforts to conserve these monumental sites 20 years on.

It has been such a pleasure working with like-minded and dedicated professionals, both in my own National Park, but also with colleagues throughout the family of British National Parks, and Historic England and Natural England. We’ve shared experiences and ideas to the betterment of our discipline from research to management, and also shared the excitement of attempting to bring our subject, which we love, to life for anyone who cares to see and to get involved.

Practical Chemistry

Aside

Following on from our last blog post about lime mortars and traditional buildings – there are a series of upcoming workshops over the next few months on using hot mixed and other traditional lime mortars, aimed at practitioners in the north of England.

Further information – lime-mortar-workshops-january-to-march-2017

The Chemistry of Buildings

Building Conservation Team

The Building Conservation team at the National Park have a vested interest in keeping the area’s traditional buildings in good repair so as to maintain and secure this particular element of the North York Moors’ special qualities. We have a new Advice Note on using lime mortars, the rudiments of which are explained below.

Most buildings in the North York Moors were traditionally constructed using stone and lime mortars (to bind the stonework together), often with earth and rubble filled cores. Lime was used for bedding and pointing the stonework and for rendering. Rendering with mortar was used to cover poorer-quality masonry underneath or to make a building more weather proof, for example on the coast. Most historic buildings were constructed from materials found locally and this contributes to what is distinctive about the ‘local vernacular’.

When it comes to repairing a surviving traditional building it is important to understand how they work. These buildings are usually of simple construction and built using breathable materials. Bricks and stone are bonded with flexible and permeable mortars made of lime and sand which allow the building to ‘breathe’. When it rains moisture is absorbed into the external surface but is then able to evaporate through the more porous pointing or render. Using a lime based mortar or render for repairs nowadays means that this process can continue.

In contrast modern cement mortars and renders along with plastic paints, waterproof sealants and damp-proof courses all act as barriers to a traditional wall’s natural ability to breathe. The trapping of moisture within permeable materials like stone can exacerbate the very problems these products are trying to resolve. The use of cement-based mortars can have a significant negative visual (photo below left) and physical impact on traditional historic buildings. The photo below (right) shows the extent of stone decay caused by the use of a cement mortar. Because the cement is much harder than the stone, moisture cannot evaporate through the joints and instead evaporates through the stone causing it to ‘weather away’ through premature erosion.

You can usually tell what type of mortar has been used most recently; cement based mortars tend to be dark grey and hard in appearance and texture whereas lime based mortars are generally lighter and softer in appearance and texture. Because they allow the surrounding masonry to dry out the colour of the stone will also lighten.

There are a number of different types of lime mortars/renders. Replacing like for like is important.

Non-hydraulic lime is the raw material produced when limestone (calcium carbonate) is fired, often called ‘quicklime’ (calcium oxide). It is sold in a slaked form (with water) as lime putty which is then mixed with an aggregate (e.g. sand) to produce mortars and plasters. These putty limes possess good breathability and flexibility and are ideal for use with soft porous materials allowing the maximum permeability.

Hydraulic lime comes in powdered form and will start to set as soon as it comes into contact with water. It is ideal for use in wet or very exposed situations or where there is a need for a higher compressive strength or a quick set. Hydraulic limes come in a variety of strengths e.g. NHL2, NHL3.5 and NHL5 – the higher the number the less flexibility and breathability the mortar will have.

Hydrated or bagged lime is a form of non-hydraulic lime which is sold as a powder. It is sold by builders’ merchants as an additive for cement mixes in order to give modern cement mixes more plasticity and workability. It is generally considered to be inferior to lime putty, not least because an unknown proportion will have reacted with carbon dioxide and set by the time it reaches the site.

Hot-mixed lime is made when quicklime is mixed with water and aggregate simultaneously. The vast majority of historic lime mortars were probably hot-mixed. There are several benefits of using a hot-lime mortar: it can produce cleaner work as there is less leaching, it has a easily-workable elasticity which produces solid and full joints, it appears to be more breathable and therefore more compatible with stonework, and it has potential for use in colder weather notwithstanding the requirement for protection from freezing during the curing (setting) process.

A standard pointing mix consists of a lime mortar mix of 1:2½ lime:sand (sand mix of 50% sharp sand and 50% builders sand) for a slightly recessed bagged finish. However there may be times when a bespoke mix is required such as when different colour sand is needed to match existing historic mortar.

Repointing is only needed where mortar has become loose, decayed or eroded to an extent that water has started to penetrate the joints. If the mortar is firm or so hard that it needs to be chiselled out then it is best to leave it in place as removal could damage the masonry. The repointing of delicate ashlar joints (made out of worked stone) is not generally advisable as the joints are so fine that getting old pointing out can lead to irreversible damage of the masonry.

If repointing is necessary joints should be carefully raked out manually or by non-electric tools (no angle grinders) to a depth equal to one and half times the width of the joint and never less than 35 mm. Great care must be taken to keep the edges of the stone intact and joints should never be widened. Work should not be carried out when there is a danger of frost or heavy rain (this is less important when using a hot lime mix). Mortar must be protected from drying out too quickly from wind, rain and frost by protecting the area. Rain must never be allowed to strike the mortar and stonework until the setting process is complete.

The mortar should be stippled as the initial set takes place, with a stiff bristle brush, to produce a textured appearance capable of shedding water and slightly set back from the stone outer surface to ensure the full arris (edge) of each stone shows clearly in relief.

The photo below (left) illustrates a good lime mortar mix and pointing method. The aggregate used in the mix has been exposed by brushing back the pointing to a recessed finish which allows the stone to be the dominant feature. The other photo below (right) shows historic pointing on an old outbuilding where roof tiles were used to fill in larger gaps between the stones, adding to its particular character and appearance.

This Exploited Land – a poetic mix of Victorian beauty and brass

Tom Mutton – TEL Programme Manager

When businessmen visited the Beck Hole Ironworks in 1860 their report in the Whitby Gazette gave a beautifully poetic account of this new enterprise. Despite the author’s lyrical writing style the article also illustrates a perceived total domination over the natural world that was the foundation of the industrial revolution.

This is partly what This Exploited Land is all about. Although in modern times we may miss the elegant language of the Victorian era, many of us have a very different view of the natural world and the potentially devastating effects of humanity’s exploitation of the planet. The way that nature has reclaimed the mines of the Esk Valley and Rosedale is humbling to see and shows us that we are surrounded by a beautiful and fascinating world that we should use our intellect to care for rather than abuse. To do this best we need to remember and learn from the past, being inspired by the monumental relics in the landscape and the stories from our ancestors who lived very different lives in the North York Moors we now enjoy.

Transcribed from Whitby Gazette 16 June 1860:

“…It is our pleasing duty to report the successful operation of the Whitby Iron Company’s (Limited) Works, at Goathland, which we noticed in our last impression as having been blown in on 7th inst.

A few of our principal townsmen spent Monday evening at those Works, and were delighted with the various departments. The magnificent engine which supplies the blast for smelting the iron from the ore moves round like a thing of life, and at once the ever-lasting hills of the valley resound with the voice as of a tide bursting upon our shores.

We heartily wish the Company success, as the pioneers in a pursuit which is destined to revolutionise the habits and maxims of the valley of the Esk, and with the facility of the rails and our own good port, we venture, the day is not distant when capital and enterprise will demand that the whole of the district become one grand scene of industry, and that, from one end of the valley to the other, Old King Coal, supported by the genius of man, will assert his power in developing those vast storehouses of wealth which, during the last few years, have attracted the attention of strangers to those exhaustless beds of minerals which nature has provided and stored up in this locality, for the use of man in the arts of civilised life. And Whitby will one day have to rejoice in the fact, that she is one of the principal ports in the kingdom for the export of iron to the commercial ports of the world.

Beckhole, the little village at the head of the valley where these works are situate, has now a strange sight to look out upon morning and evening, which are ushered in with a torrent of molten iron and a flood of lava gushing forth from the bowels of the company’s furnace. The sweet songsters of the woods and glens are now giving up their claim to the morning’s dawn and evening calm. The _________ voices of the sons of toil mingling with the music of the compressed air of the blast engine, wait for the dawn of the East, whilst the perpetual columns of vapour, smoke, and flame, tell of the presence of man, successfully reducing to practice the maxim of the company’s tablet, viz “Tis the prerogative of man to command, develope, and appropriate to his service the elements with which God has surrounded him.” The tablet at the foot of which the above inscription is fixed commemorates the incorporation of the Company, the date at which the first Iron was made upon the Works, and the names of the Directors; and was cast from the Iron first run from the furnace.

In this noble course of action the W.I.C.L., have led the way. We heartily wish them god speed, and doubt not the success which awaits their spirited enterprise; and hail with joy the event as a blessing to the surrounding neighbourhood, and the watchword to the progressive establishment if similar works, whose effect will be to convert this district into one of the most thriving seats of the iron trade of this country, creating labour for man and beast, and scattering in its train the blessings of trade hitherto unknown in the locality.”

This tablet, referred to in the article and cast from the first Esk Valley iron, can be seen today in Whitby Museum.

It’s worth noting that Whitby Iron Company Limited was short lived – it was wound up in 1862.

Can you help?
There are two words in the article that are obscured by a tear in the paper from which it was transcribed – can you suggest what the missing words before ‘voices of the sons of toil…’ might be? please let us know.
