When is a woodland a wood?

Mark Antcliff – Woodland Officer

The National Park Authority has played a role in creating more than 600 hectares of new native woodland since the turn of the century, with something in excess of half a million trees established.

But when is a new woodland actually a wood and how do you measure the success of a habitat created?

In terms of tree growth the first milestone is when the young trees are fully established and have outgrown the competing vegetation and the attention of voles, rabbits, deer and livestock and their teeth. The second is when the branches of the new neighbouring trees meet – this is called “canopy closure” – from which point the ground flora will alter as shade tolerant and shade loving species will have better success, including our beloved bluebells. Perhaps a third is when the new trees reach a stage where they could be used to produce wood and timber through thinning or coppicing.

I was thoughtful of this question when revisiting a site that was planted about 16 years ago in Bilsdale. Here the area of an existing woodland had been extended by new planting, mainly young oak trees.Existing area of Ancient Woodland in Bilsdale. Copyright NYMNPA.

There were some initial challenges caused by a faulty batch of plastic tree shelters that degraded faster than they should have leaving the new trees vulnerable. However the trees are now fully self-supporting and I can walk under them, which for me personally is a good moment as I can then consider myself in a wood rather than looking at it. The icing on the cake however is that some of the trees planted 16 years ago are now producing acorns, a sign that a true self-regenerating woodland has been created.

Buoyed by such success we have, with the cooperation of the land owner and his agent, planted an additional area of 3 hectares this winter. I can’t wait to see how this new woodland extension looks in another 16 years’ time, alongside the ancient and post-millennial woods already in place.

As a Woodland Officer, I do tend to think in the long term.

Inside a coniferous forest

Dirge in Woods by George Meredith

A wind sways the pines,
And below
Not a breath of wild air;
Still as the mosses that glow
On the flooring and over the lines
Of the roots here and there.
The pine-tree drops its dead;
They are quiet, as under the sea.
Overhead, overhead
Rushes life in a race,
As the clouds the clouds chase;
And we go,
And we drop like the fruits of the tree,
Even we,
Even so.

Loving Levisham Estate: a personal view point

Rachel Pickering – Natural Environment Team Leader

Every day (when I am not at my desk) I take the dog for a walk past ‘the view point’ and every day I love it!  How could you not?

‘The view point’: view from Newton on Rawcliffe looking north east over Levisham Moor

My favourite version of the view is when the wisps of mist are still stuck to the trees in the valley even when the rest of the morning mist has long since left. I get to admire the landforms – Newtondale, the finest example of a glacial-lake overflow channel in England, carving through the striking two tiered moorland plateau. If I time it right I can hear and sometimes see a steam train chugging and tooting its way into Levisham Station down in the valley.

What makes this view extra special for me in particular is that it comprises part of Levisham Estate which I manage, alongside our Senior Ranger David Smith, for the National Park Authority. Between us we ensure that the Estate, which has been owned by the Authority since the 1970s, is managed for National Park purposes. As well as the stunning landscapes it boasts some outstanding wildlife habitats and a full range of archaeological curiousities including scheduled monuments.

It’s not just me that thinks its special. The majority of the Estate is designated as a Site of Special Scientific Interest (because of succession habitats, botany and geology), with the moorland also being designated as a Special Protection Area (because of merlin and golden plover populations) and a Special Area for Conservation (because of heathland habitats).

The majority of the Estate’s 3,358 acres are heather moorland but it actually includes a bit of everything. Here are a few of its gems:

Over the years we’ve been carrying out projects to conserve and improve the Estate. Here are a few examples of these:

The Estate is a great place for volunteers to get involved. Over the last few years 4,000 of the trees planted are thanks to our committed volunteers. It has also proved to be a useful place for our Apprentice teams to practice their newly learnt skills including heather burning, bracken and scrub control, and fencing.

The Levisham Estate is a big commitment and a rewarding place for many people, not just me.

Footnote
I confess that I am feeling rather reflective at the moment as a couple of colleagues who have been working at the Park for even longer than me (over 18 years) are about to leave. I grew up near to Levisham Estate and have seen the changes close up, over time. A few years ago the following photos of ‘the view point’ were included in the ‘Now and Then’ photographic exhibition at The Moors National Park Centre, Danby. It was rather strange, but striking, that on the day I went to take the ‘now’ photograph there just happened to be four walkers sat on the bench. They were fascinated to see the level of change to the landscape and fortunately were very happy to be slightly rearranged to replicate the ‘then’ photograph.

MAGNETITE

As mentioned previously, in the 1850s a seam of iron rich ironstone was discovered in Rosedale. Also known as lodestone, magnetite had long been a valued mineral because of the amount of iron ore it contains, so much so that it is often magnetic.

Rosedale - copyright Colin Dilcock, NYMNPA

The discovery in Rosedale led to the rapid development and expansion of the mining and calcining industry there and in the wider area. There were great expectations …

“Professor Phillips delighted and informed the company by his description of the ‘Ironstones of Cleveland’ … The Rosedale band at its richest points, yielded 50 per cent [ore] and in many places 42 per cent. The Rosedale stone was magnetic and contained phosphorous, it was not merely magnetic, but it had an inherent magnetic polarity … There must spring up over the Cleveland district, through the working of the iron ore, great towns, with a numerous and active population; and, as a result, the moorland would be brought under cultivation and this once dismal tract of 20 square miles would rejoice in all the material means that could promote human happiness and prosperity…”

From a meeting of the British Association for the Advancement of Science at Leeds, as reported in the Manchester Courier and Lancashire General Advertiser, 2 October 1858.

However the actual magnetite seam was soon exhausted leaving the industry exploiting poorer ironstone and slowly declining into the 20th century. The magnetite proved to be rather a flash in the pan.

MESOTROPHIC LAKES

There are very few natural lakes in the North York Moors due to geology and climate, which makes Lake Gormire on the south western edge of the National Park even more remarkable. In the last Ice Age a hollow was formed by a meltwater channel between the edge of the moving Vale of York ice sheet and the edge of the North York Moors gritstone escarpment. The channel damned up and the lake left behind divided into two bodies of water – Gormire and the much smaller, Buttermere.

These are mesotrophic lakes – containing a narrow range of nutrients in medium concentrations. This type of lake chemistry is rare and becoming rarer as lakes are effected by artificially increased levels of nitrogen and phosphorus and so become eutrophic. Lake Gormire is surrounded mainly by semi natural woodland and fed by springs and so largely circumvents the risks of artificial diffuse pollution and nutrient enrichment.

Because of their chemistry Mesotrophic lakes can support higher levels of diversity of macrophytes (algae), aquatic plants, invertebrates and fish. The fen (‘mire’, ‘mere’) plants around Gormire/Buttermere reflect the acid soil, so there is Marsh cinquefoil Potentilla palustris, Common skullcap Scutellaria galericulata and Tufted loosestrife Lysimachia thyrsiflora, as well as Bog bean Menyanthes trifoliata and Water horsetail Equisetum fluviatile. Gormire is particularly popular with noisy water birds, mating toads and freshwater leeches, all exaggerating the primeval sense inside this Ice Age hollow.

Lake Gormire and the area around it is a designated Site of Special Scientific Interest. The cliff slope woodland above Lake Gormire is the Garbutt Wood Nature Reserve managed by the Yorkshire Wildlife Trust.

MILKY WAY

The Milky Way is a galaxy of billions of stars and planets sometimes partly visible to the naked eye as a milky looking band of light in the night sky.

We’re in the middle of the Dark Skies Festival 2017 here in the North York Moors National Park. The dark skies over National Parks make it easier to see the lights of the galaxies around us. This February is particularly good for viewing Orion and also a very bright Venus.

February 27 1920   The mysterious stars

…Later in the evening a half-moon shone in a filmy sky across which, from S.E. to N.W., ran a Noë-ship of thin white clouds. A soft mist hung in the far valleys, but the nearer moory slopes loomed clearer. In the pastures the furze bushes were startlingly like huge black beasts grazing on the rimmed herbage. No sounds broke the utter silence of the moonlit hills; the wind had almost died away, but as I stepped over the little rill from Thunderbush Farm [Commondale], I heard its faint, musical ripple.

The ever-mysterious stars flashed through the interspaces of the filmy clouds and circled silently above the dim earth. Sirius flashed due south whilst mighty Orion hung high above the moor edge, his glory somewhat dimmed by the moon. What would life have been without the stars?”

MINI-BEASTS

We use the term mini-beasts for the tiny invertebrates that go without notice until they’re looked at under the microscope and a menagerie of marvel and dread is revealed.

Identifying and counting river invertebrates is a very useful way of assessing the health of a river at a particular spot. Certain species indicate good water quality and others, poor water quality; a change in species/numbers indicate a change in water quality e.g. a pollution incident. There is a national programme of riverfly monitoring led by the Riverfly Partnership. Results are recorded centrally and indications of a potential incidents are reported to the Environment Agency. The National Park run a number of local Riverfly Monitoring Workshops for volunteers – the next one is 1 March.

MOSCHATEL Adoxa Moschatellina

Moschatel is a perennial unobtrusive plant which likes the damp, shady conditions found along woodland edges and on shaded hedge banks. It flowers between March and May, producing five lime green flowers on top of a leafless stalk, four flowers face outwards and one flower faces upwards, forming a cubic which has led to the plant’s other common name – Townhall Clock. The plant grows along the ground through rhizomes with the flower stalks growing up through its leaves to only c. 15cm tall. It is a common plant but easy to miss – look out for it in early spring before it gets hidden by taller plants.

MOTTE AND BAILEY

Historic England suggest there are over 600 motte castles or motte-and-bailey castles in England. These were early medieval fortifications built by the Normans and made up of a large mound of earth/rubble (the ‘motte’) with a defensive palisade and tower on top, and an embanked enclosure with other buildings (the ‘bailey’) adjoining.

A motte and bailey castle could act as a fort when required as well as providing the residence for the local landowner/representative of the King and a centre for feudal power. They were often built on high ground to take advantage of the extra height to dominate the landscape and overlook access routes.

Soon after the beginning of Norman rule in England came the ‘harrying of the north’ – a military campaign to overcome and overwhelm the population in the north of the country and hammer home the idea that the Normans were here to stay. The new motte and bailey castles were a highly visible tool for holding that ground and reinforcing that message.

By the 13th century castle design had moved beyond the basic motte and bailey. Although the timber structures have largely gone, the earthworks are often still traceable in the landscape, and rubble mottes and the remnants of stone towers remain. Many are scheduled. Examples in the North York Moors include Hood Hill, Easby motte, and Foss Castle.

MOTHS

Moths are often considered the poor cousins of butterflies in the Lepidoptera family. The most obvious difference between butterflies and moths are that the former are active during the day whereas moths are mostly (but not all) nocturnal, feeding on the nectar of night blooming/night scented plants. Another difference is that when resting, butterflies usually close their wings whereas moths leave theirs open and this makes it easier to examine their intricate patterning and refined colouring. But as with most ecological questions – what is the difference between butterflies and moths? – there is no obvious answer and always an exception. Moths can be just as colourful, just as beguiling and just as in peril, as butterflies. For more on moth conservation see here.

Shandy Hall, Coxwold has become a location for moth study and reporting over the last few years. The gardens there provide a semi-natural/cultivated habitat for many species – over 400 different species have been recorded in the gardens to date.

Ageing Mussels

Simon Hirst – River Esk Project Officer

As mentioned previously, the River Esk in the North York Moors is the only river in Yorkshire with a Freshwater pearl mussel population Margaritifera margaritifera. The population is estimated to be comprised of approximately 1,000 individuals and is in drastic decline, so much so that it is on the verge of extinction. The decline is due to a number of linked causes such as water pollution, choking of the river bed by sediment build-up, deterioration in fish numbers and habitat degradation.

We’re working to improve the riparian habitat and so help secure the local population of Freshwater pearl mussel in the River Esk. We recently sent a sample of mussel shells from the Esk* over to the Swedish Natural History Museum in Stockholm, in order to determine the age of the mussels in the River Esk. The maximum age of Freshwater pearl mussels in the wild has been shown to vary considerably, from a low of 35 years in Spain (warmer, lower latitude rivers) to over 200 years in arctic areas (colder and high latitude rivers). Information from the ageing study would tell us how long we have left to save the Esk population from extinction and help identify the approximate time when the River Esk mussel population went into decline.

Dr Elena Dunca from the Swedish Natural History Museum sectioned (cut though) the shells supplied and then counted the growth lines on the mussel shell using a high powered microscope.

This age/length graph will allow us to age fairly accurately any mussels we find in the wild in the future just by measuring them.

A total of 10 shells were aged by Dr Dunca, and the graph below shows that the mussels sent to Sweden ranged in age from 45 to 88 years of age.  The mussels in the River Esk also showed normal growth rates.

Esk FWPM - Length frequency graph - Swedish Natural History Museum

Length frequency graph of mussels in the River Esk

The smallest live mussel we have found in the Esk up to now was 75mm (approximately 28 years of age). This means the last time the Esk mussels reproduced successfully in the wild was in the late 1980s. The largest mussel we have found in the Esk was 156mm (approximately 100 years of age), which means it was born around the time of the First World War. The vast majority of the mussels are around the 130mm-140mm size range (approximately 80 years of age). We now know for scientific certainty that the Esk has an ageing population in need of help!

The best hope for our mussels is for them to start to successfully reproduce again. We’re working with the Freshwater Biological Association (FBA) who are carrying out captive breeding work in the Lake District. We hope to re-introduce the captive bred young Esk mussels from the FBA Facility back into the Esk once the riparian habitat is restored enough to sustain them, and so ultimately stop this species from becoming extinct in the wild (of Yorkshire).

* Please note – No mussels were harmed in the making of this study! We used empty shells that were found on the banks of the Esk.

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.

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.

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.

Cosy and warm

John Beech – Land Management Adviser

Hygge (pronounced hoo–gah) has been a major trend for this Christmas period. It’s a Danish ‘concept’ of living cosily e.g. wearing thick socks whilst drinking hot chocolate and watching Murder She Wrote – which can make us feel better about the icy and harsh season outside.

For a number of wild animal species, they have their own version of hygge except for them it’s a necessary survival mechanism. Hibernation is an extended period of deep sleep, or torpor*, which allows animals to survive the winter extremes. By reducing their metabolic rate and lowering body temperature this enables them to sit tight, conserve their energy and survive through the cold periods when food is scarce or has little energy value. *Animals in a state of torpor rather than sleep can venture out to try and find additional supplies during warmer winter spells.

In autumn as the temperature begins to fall and the nights draw in, many of the small mammals that live in our fields, woodlands and hedgerows forage for extra food to store over the winter and look for a suitable site (a hibernaculum) to hole up in for the coldest part of the year. Autumn months are often one of the better times of year to see small mammals in the North York Moors such as mice, voles, shrews and Hedgehogs (Erinaceus europaeus) out and about eating vast quantities of food to build up fat reserves which will carry them through to the spring.  Following this period of feasting they retreat to somewhere suitably warm and undisturbed and begin to enter into a period of hibernation, which can last for up to four months of the year depending on the harshness of the weather. Also in autumn bats relocate to hibernation roosts looking for a constant temperature and to avoid frosts and freezing e.g. caves, trees and built structures.

And it’s not just our small mammals that hibernate:  Queen bees dig in for the winter and also some species of moths and butterflies, like the Duke of Burgundy (Hamearis lucina) which hunker down in grassy tussocks. Many of our reptiles and amphibians also hibernate. Adders find warmer crevices under boulders or in dry stone walls. Newt species spend the winter in the muddy banks of ponds, under paving slabs, piles of wood or in a handy compost heap. Common Toads (Bufo bufo) sleep out the winter buried deep in damp places such as leaf piles or compost heaps, before emerging to travel back to their traditional breeding sites in early spring. The Common Frog (Rana temporaria) which needs to keep damp is able to partially freeze in its state of hibernation before thawing out in spring. Occasionally such species come out of hibernation during any short sunny spells in the winter to make the most of the weak sunshine, only to return to their hiding place when the temperature falls again.

Malkin Bower, Bilsdale - in winter - copyright NYMNPA.

So as you’re reading this, hopefully somewhere cosy and warm, spare a thought for our wildlife that’s out there sleeping through the winter, hidden away from view deep in their retreats, practising their own life saving hygge and waiting for the first signs of spring.

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.
