Adrian Stephens and the ‘Steam Whistle’

by Laura Bray

Following on from the recent article about J.O. Francis’ romantic reminiscences of the railway, you have to ask – what is a railway without a locomotive and what is locomotive without a whistle?

“The Western Mail” had an answer, printing, on Friday 4th January 1935, an article with the banner “Romance of the First Steam Whistle”.

Like so many inventions, the steam whistle was born in the Dowlais Iron Company.  Its inventor was Adrian Stephens, a Cornishman by birth, who had come to Merthyr in the early 19th century, and had initially worked as Chief Engineer at the Plymouth Iron Works before moving to a similar role in the Dowlais works in about 1827.  Here he had charge of the mill and the blowing engines.

Never a place blessed with health and safety standards, iron working was particularly dangerous, and in about 1835 there was an explosion where one of the old non-tubular boilers burst, with the loss of several lives.  An investigation into the incident suggested that there was negligence – smoke and grime had made the safety gauges unreadable, and the stoker had failed to ensure an adequate supply of water was pumped in.

John Josiah Guest tasked Adrian Stephens with the job of finding a way to prevent a reoccurrence, and after some experimentation with a long tube similar to a tin whistle, and then some organ pipes that Stephens asked Guest to source, he eventually came up with a local copper tube, made like a bosun’s pipe, but wider and with a larger vent.  The end of the tube was fixed to the top if the boiler, with the other held submerged in the water in the boiler.  As the water ran dry, the steam was pushed up the pipe and a shrill whistle sounded, thereby allowing action to be taken before the pressure caused an explosion.  Not surprisingly, the workers hated it, regarding it as a nuisance to be put out of action.   Stephens therefore enclosed it in a cage, and it was in this form that it was adopted by all the Merthyr ironworks – and then added to every boiler, railway locomotive and steam ship around the world.

Stephens did not patent his invention.  Writing to his niece in 1872 he said “Neither in want, nor caring for money at the time, I did not think of taking a patent”.  He was even unsure about which year he had introduced it, guessing 1835, as it was before Guest was created a baronet (1838).

But his steam whistle was not the only railway connected achievement – Stephens was also credited with planning the “Lady Charlotte”, the first locomotive to be used at the Dowlais Works.

After Guest’s death, Stephens moved to the Penydarren Ironworks, where he invented, according to his son, the “Hot Blast”, which made the furnaces hotter and more efficient, before ending his career as a Civil Engineer for Anthony Hill in the Plymouth Works.

Stephens died in 1876 by which stage his invention had revolutionised steam safety.  He is buried in Cefn Cemetery, within hearing distance of the Merthyr-Brecon/LNWR trains whistling up and down the track.

So the next time you hear the “whoo whoo” from the heritage railway or the magnificent Flying Scotsman, think of Adrian Stephens and Merthyr’s role in that Age of Romance.

Memories of Old Merthyr

We continue our serialisation of the memories of Merthyr in the 1830’s by an un-named correspondent to the Merthyr Express, courtesy of Michael Donovan.

Now it always occurs to me that the doctoring system is a remainder of what in other cases would be called the truck system. Pray understand, I know how careful and skilful medical men are generally, and how admirably they perform their duties, yet there is always the thought that the system does not always co-ordinate with those general principles adopted in other things.

My own conviction is that truck in the early age of Merthyr was actually a necessity. When the works really began they were small, and no certainty of continuance. I am well aware of attempts that have been tried in various systems to alter it, but the system seems too firmly rooted to be altered for some time at least. An experiment in the adoption of a another method is, I believe, now being tried.

After a while Plymouth had Mr Probert (who by the bye, had been an assistant of Mr Russell), and so remained until his death, I think, but yet doubt that he resigned previously. Penydarren had Mr John Martin, and Mr Russell retained Dowlais, but it passed into the hands of his nephew Mr John Russell, for some time, and on his leaving Dr John Ludford White came to Dowlais.

This gentleman married a niece of Mr Wm. Forman, of the firm of Thompson and Forman, Cannon House, Queen Street, London, and after some years moved to Oxford, with the intention, it was said, of taking higher degrees. Dr White obtained the appointment through the recommendation of the London physician of Sir J John Guest, and in order that an accurate knowledge of the requirements might be, had visited Dowlais to see for himself. I remember him there, and an incident followed that will be mentioned when Dowlais is visited which will show the kind-heartedness of Sir John, and I hope also to mention one demonstrating his decision of character and another where I saw him weep.

We now return to Mr Russell’s surgery. A little further down, on the other side was Adullam (sic) Chapel, and cottages thence to the road to Twynyrodyn, while on the same side as Mr Russell’s was the way from the High Street, John Street by name, cottages somewhat irregular. The old playhouse also stood here; yes reader. It was a stone and mortar structure, and was for a long time unused.

Further on there was the Fountain Inn, between which and the Glove and Shears the road passed to Dowlais over Twynyrodyn, Pwllyrwhiad etc, but we cross and a few yards brings me to what was the boundary wall of Hoare’s garden, which continued down to where the line to Dowlais is now.

The bottom end of Tramroadside North from the 1851 map

It has been my pleasure to see many gardens, but in all my experience I never saw one kept in such trim as this. Upon its being taken for the railway, Hoare started a garden and public house, if I remember well, at Aberdare Junction. Owing to the Taff Vale Company not allowing anyone to cross the line, a very long way around became a necessity to get there, and he did not do as well as anticipated or (I think) deserved.

Lower down the tramroad were some cottages on the right hand side, in one of which, adjoining the Shoulder of Mutton, a cask of powder exploded. It was kept under the bed upstairs for safety, and, lifting the roof off its walls, it fell some dozen yards away. The roof was covered with the thin flagstones often used and very little damaged. No one was fatally injured but one or two were injured, and altogether it was a wonderful escape. Moral: Do not keep a cask of explosive material upstairs under the bed!

Merthyr’s Ironmasters: G T Clark – part 2

This article is a transcription from a publication now in the public domain:  Dictionary of National Biography (1st supplement). London: Smith, Elder & Co. 1901

On the formation of the British Iron Trade Association in 1876, Clark was elected its first president, and his ‘Inaugural Address’ (Newcastle-upon-Tyne) attracted much attention, provoking considerable controversy in the United States by reason of its trenchant exposure of protection. Few employers of labour have ever studied the social well-being of their workers so earnestly as Clark. At his own expense he provided a hospital for the Dowlais workmen, while the Dowlais schools, the largest in the kingdom, owed their success almost entirely to his direction. He was an early supporter of the volunteer movement, and himself raised a battalion in the Dowlais district. He was chairman of every local authority in the place, and his manifold services in the work of local government are commemorated by a marble bust, the work of Joseph Edwards, placed in the board-room of the Merthyr poor-law guardians. He was sheriff of Glamorganshire in 1868.

George Thomas Clark by Joseph Edwards

Clark’s reputation, however, mainly rests on his archaeological work, and, to a lesser extent, on his historical research, though these were but the relaxations of an otherwise busy life. For half a century he was recognised as the highest authority on all mediæval fortifications, and was the first to give a clear insight into the military and historical importance of the earthworks of this country, and especially to show the use made of the mound – ‘the hill of the burh’ – in Norman times. Before going to India he took a prominent part in the movement which brought about the foundation in 1843 of the Archæological Association (now the Royal Archæological Institute), and, after his return, was constantly associated with its work for the rest of his life contributing papers to its journal, attending its annual meetings, and acquiring a unique reputation as a field-lecturer, inasmuch as the castles visited were ‘called up to their first life by his massive vigour’.

He was also one of three trustees of the Cambrian Archæological Association. Commencing with an account of Caerphilly Castle as early as 1834, he contributed to the ‘Transactions’ of various societies, and to the ‘Builder,’ a large number of articles dealing with his favourite subject. In 1884 these were collected in his ‘Mediæval Military Architecture in England ‘ (London, 2 vols) a work which is not likely to be superseded, though its information may be supplemented with minor additions of detail.

Next to his purely archaeological attainments should probably be ranked his knowledge of heraldry and genealogy. He wrote the article on heraldry for the ‘Encyclopædia Britannica,’ while his privately printed pedigree of the Babington family has been described as ‘perhaps unsurpassed for its dimensions and grandeur of type.’

His other works were for the most part elaborate contributions towards the history of his adopted county of Glamorgan, the following being the more important among them:

‘Thirteen Views of the Castle of St. Donat’s, with a Notice of the Stradling Family,’ Shrewsbury, 1871.

‘Some Account of Robert Mansel and of Admiral Sir Thomas Button,’ Dowlais, 1883.

‘The Land of Morgan, being a Contribution towards the History of the Lordship of Glamorgan,’ London, 1883, 8vo.

‘Limbus Patrum Morganiae et Glamorganiæ. Being the Genealogies of the Older Families of the Lordships of Morgan and Glamorgan,’ London, 1886, 8vo. Most of these pedigrees had been published ‘nearly a quarter of a century’ previously in the ‘Merthyr Guardian.’

‘Cartæ et Alia Munimenta quæ ad Dominium de Glamorgan pertinent.’ Sumptuously printed, for private circulation only, this great collection of Glamorgan charters extends to 2,300 quarto pages, making four volumes, of which the first was issued in 1885 from a private press at Dowlais, and the other three (in 1890-1-3) from Cardiff.

Clark also edited some devotional works by his father and his ancestor, Samuel Clarke (1599-1682), and wrote numerous articles on the history and antiquities of Glamorgan.

Clark died on 31 Jan. 1898 at Tal-y-garn, near Llantrisant, where he had resided during his later years, and was buried there at St. Ann’s Church, which he had built to the memory of his wife, Ann Price, second daughter of Henry Lewis of Greenmeadow, near Cardiff, and coheiress of Wyndham Lewis. She was married to Clark on 3 April 1850, and died on 6 April 1885, leaving a son (Godfrey Lewis Clark) and a daughter.

Merthyr’s Ironmasters: G T Clark – part 1

This article is a transcription from a publication now in the public domain:  Dictionary of National Biography (1st supplement). London: Smith, Elder & Co. 1901

George Thomas was born in London on 26 May 1809, the eldest son of George Clark (1777–1848), chaplain to the royal military asylum, Chelsea, and Clara, only surviving daughter of Thomas Dicey of Claybrook Hall, Leicestershire, and he was educated at the Charterhouse. Adopting engineering as a profession, he was entrusted by Brunel with the construction of two divisions of the Great Western Railway; the Paddington terminus and the bridges at Basildon and Moulsford being his principal works While thus engaged he compiled ‘A Guide-book to the Great Western Railway, containing some Account of the Construction of the Line, with Notices of the Objects best worth Attention upon its Course’ (London, 1839). This, the first guide to the line, was published officially without his name, and dedicated to Brunel. A more detailed account, which he subsequently wrote, of the geology and archæology of the country traversed by the railway, was published, with numerous illustrations, as ‘The History and Description of the Great Western Railway’ (London, 1846); but the only name attached to it was that of the artist, John C. Bourne.

In about 1843 Clark went to India, where he was employed by the government to report on the sewerage of the native town at Bombay, and afterwards upon the extension of the salt works of the district. Here he advocated the construction of the first railway in India, that from Bombay to Tannah, afterwards merged in the Great Indian Peninsula Railway, for the promoters of which he also reported on the feasibility of an extension through one of the mountain passes of the Sahyadri or Western Ghauts. On account of the climate he declined an offer of the chief engineership of the new line and returned to England. In consequence of an article on sanitary reform which he contributed to the ‘Westminster Review,’ he was appointed a superintending inspector under the Public Health Act, 1848, and reported on the sanitary condition of a large number of towns and districts, in many of which local boards were formed through his efforts. His success as an inspector was recognised by his promotion to be one of the three commissioners which then constituted the general board of health.

Towards the close of 1852 Clark, however, became trustee of the Dowlais Estate and Ironworks, under the will of Sir Josiah John Guest. For some time previously the works had been carried on at a loss; but having procured the necessary capital and induced Henry Austin Bruce (afterwards Lord Aberdare) to share with him the responsibility of the trusteeship, Clark took up his residence at Dowlais and devoted all his energies to the development of the works and the redemption of the estate. As Bruce devoted himself to politics, the whole responsibility of management devolved on Clark alone, whose rare capacity for administration was displayed no less by his rapid mastery of a complicated situation than by his wise selection of heads of departments, chief among whom was his manager, William Menelaus.

To Clark and Menelaus belongs the credit of being the first ironmasters to assist (Sir) Henry Bessemer to perfect his process for making malleable iron direct from the ore. The inventor was invited to Dowlais to conduct experiments, with the result that the first rail ever rolled without the intervention of the puddling process was produced at Dowlais. The prompt adoption of Mushet’s further invention enabled Dowlais to be first in the field in the production of steel rails, and to enjoy for some time the monopoly of that trade in Wales. The consequent expansion of the industry, and the difficulty of procuring an adequate supply of suitable ores at home, led Clark, in conjunction with the Consett Iron Company and Messrs. Krupp of Essen, to acquire an extensive tract of iron-ore deposits near Bilbao in Spain.

A Bessemer Converter

To render the works independent of the vicissitudes of the coal trade he also purchased large coal areas, undeveloped for the most part, in Glamorganshire. To save the inland transport he finally procured the establishment, in 1888-91, of furnaces and mills in connection with Dowlais, on the seaboard at Cardiff. He was induced by Lord Wimborne (Ivor Guest, eldest son of Josiah John) to continue his administration of the Dowlais undertakings down to the end of March 1897, though his trusteeship had expired more than twenty years previously. Under his regime Dowlais became in effect a great training school which supplied to similar undertakings elsewhere a much larger number of managers and leading men than any other iron or steel works in the country.

Memories of Old Merthyr

We continue our serialisation of the memories of Merthyr in the 1830’s by an un-named correspondent to the Merthyr Express, courtesy of Michael Donovan.

There has not been much reference yet to Caedraw, nor can there be much recalled to describe. The Gas Works were erected here, a Mr Evans being the first manager, and a brother of his the deputy. There were two breweries near the end of the road joining Bridge Street, one owned by a Mr John Toop; the other, which was smaller, owned by Mr Anstie, who kept the shop in Pontmorlais previously. This Mr Anstie bought the property between the road in Caedraw and the Isle of Wight, and came to reside there after improving the buildings.

A section of the 1851 Public Health Map showing Caedraw

The basin tramroad was ordinarily used as a pedestrian thoroughfare, in fact many houses had no other way of approach. I cannot recall anyone ever being prevented from walking the tramroad, although it might not have always been judicious to do so on account of safety. Things are so altered now, and we are accustomed to the change, that it takes consideration to recall things quite decidedly. For instance, brakes to slacken the speed or stop conveyances were unknown. The ‘sprag’ was the only thing used, and these projected at variable distances from the wheels of the trams, if the trams were going fast – for they would occasionally run wild – it was a serious matter to be caught in any narrow part of the road. It was also a hazardous thing for the haulier to put them in or take them out, and many a limb as well as life has been lost by a slip.

As one instance of there being no other way of going to or coming from a residence on the Tramroad, somewhere behind the Morlais Castle Inn can be cited. It was the residence of Mr Roger Williams (I think it was his own property). He was a public functionary, but whether relieving officer or assistant overseer is not remembered now. If we went down the Tramroad towards Twynyrodyn, before coming to Professional Row we should see a door on the right hand. This is where a Mr Russell stayed. He was a brother of the Mr Russell who was the doctor of Dowlais, Penydarren and Plymouth Works at one time. He lived in the lowest of the three houses in Professional Row, and his surgery was at the back with public entrance from the Tramroad.

Old Mr Russell, his brother, and others attended the surgery, but the one very often attendant upon the patient was the brother, about whom I remember the remark that after enquiring as to symptoms he always gave two pills in a paper, and the patients were often (very often) so hurt, that the pills used to be thrown over the Tramroad wall into the field on the other side, whence they were collected to again be served out.

George Overton, Engineer

I’m sure we’ve all heard of Overton Street in Dowlais, but do we know about the person it was named after? George Overton, engineer, is a person who figures prominently in Merthyr’s History, but about whom very little is known.

Information about George Overton’s early life is very scanty, and sources differ as to his date of birth. Some sources state that he was born on 16 January 1775 at Cleobury Mortimer in Herefordshire (others say he was born in 1774), and the next 20 or so years remain a mystery. In his 1825 publication, A Description of the Faults or Dykes of the Mineral Basin of South Wales (right), however, he would describe himself as a practical man who had made and used tramroads “… during the greater part of the last thirty years … having surveyed and constructed roads of some hundred miles’ extent in different parts of the kingdom …”

By the turn of the 19th Century, he had moved to Merthyr, and worked on the Dowlais Tramroad, connecting the Dowlais Ironworks to the Glamorganshire Canal in about 1791-3. This new 4ft 2in gauge tramroad costing £3,000, allowed horse-drawn wagons moving coal and iron – his scheme enabling each horse to pull 9-10 tonnes going downhill.

Soon after this, Overton was working on the Merthyr Tramroad. Commissioned by the owners of the Dowlais, Penydarren and Plymouth Works to counter the control that Richard Crawshay of Cyfarthfa Ironworks held over use of the canal, the 4ft 2in gauge tramroad was nearly 16km long and ran between Merthyr Tydfil and Abercynon. The tramroad secured its place in history when Richard Trevithick’s steam test took place here in 1804, two years after Overton completed his supervision.

From 1803, Overton had an interest in Hirwaun Ironworks in the Cynon Valley, as a partner in Bowzer, Overton & Oliver. He constructed a tramroad from Hirwaun to Abernant (1806-8), followed by work on the Llwydcoed Tramroad for the Aberdare Canal Company, and Brinore Tramroad.

In 1805 Overton married Mary, and they would go on to have six children.

In 1818 he was consulted by mine owners in County Durham, beginning his involvement in the development of what became the Stockton & Darlington Railway. Two canal schemes had failed to materialise and Overton recommended a horse-drawn tramway. His survey detailed an 82km route that he costed at £124,000, and was the first ever survey for a railway. After difficulties with landowners and re-surveys in 1819 and 1820 to shorten the route, his work was taken forward to Parliament but on the passing of the Bill, steam railway pioneer George Stephenson (1781-1848) took over. Stephenson’s team undertook a new survey and the rest, as they say, is history.

Overton had very definite ideas about tramroads and railways and how to construct them. His design for wooden trams (wagons) was adopted across most of South Wales. His expertise in this field seems to have prevented him from fully appreciating the advantages of steam locomotion “… except in particular instances, and in peculiar situations.” His last project was Rumney Railway, a plateway from Rhymney Ironworks to the Monmouthshire Canal Tramroad near Newport. It opened a year after the Stockton & Darlington Railway.

In 1815 Overton and his family moved to Llandetty near Talybont-on Usk where he died on 2 February 1827.

Memories of Old Merthyr

We continue our serialisation of the memories of Merthyr in the 1830’s by an un-named correspondent to the Merthyr Express, courtesy of Michael Donovan.

Still further on yet, and on the left, were other cottages and a public house called ‘The Ship in Distress’. These cottages and ‘The Ship in Distress’ have long since ceased to be tenantable, but about which I will tell something.

Mr David Morris, the grandfather of the late Mr Thomas Jenkins of Pant, kept the public house, and owing to his not voting in accordance with the wish of his landlord at an election, had notice to quit. Mr Morris then built the ‘Mountain Hare’ and removed there. So much for political pique, but another hardship soon after arose. Upon the cottages etc. becoming untenantable, the owner (who had become so by the marriage of a widow) was John Jenkins, keeping the ‘Cross Keys’ near the lock-up. He applied unsuccessfully, both to the Dowlais and Penydarren Companies, for compensation.  All he got was the part of shuttlecock, the battledores being the companies. In vain did he endeavour to invoke the aid of any solicitor to take up his case until a person (long dead), who shall be nameless, rendered assistance to him. Amongst the excuses urged by the companies was a direct negative that either had worked beneath the property, so that it became necessary to sink a pit upon that small plot and show the minerals had been abstracted. Upon so doing he was able to obtain compensation.

This, or about there for certain, was called Pwllywhead (sic) (Duck’s Pool). Beyond this there were a few cottages, which the inexorable demand for tip room has obliterated. The residence of the old mineral agent of the Dowlais Works, Mr William Kirkhouse, was on the way, and the road ran out to join that from Merthyr to Rhymney Bridge via Dowlais, above or about Cae Harris.

All this is vividly recalled by the sudden death of the late Chairman of the Board of Guardians. Mrs Jenkins, mother of the deceased gentleman, was the eldest daughter of David Morris of ‘The Ship in Distress’. There was also a son who was in the fitting shop at the Dowlais Works, and a younger sister, who married and went to reside somewhere. Do not for a moment conclude that in the turnpike gate times this road was always quite open and free to travel. Ever and anon – particularly on Wain (sic) Fair days – there was a chain stretched across and a collector stationed who required payment before removal of the obstruction.

No doubt many of your readers have heard of a horse and rider going over the bridge and into the gorge at Pontsarn. Let me assure them that it arose from the anxiety to save the payment of toll, and in due time it shall be made clear, for I had the words of the person some few years ago.

The Dowlais Boiler Explosion of November 1836

by Victoria Owens

185 years ago today, a terrible explosion occurred at the Dowlais Ironworks. To mark the anniversary, eminent historian, and biographer of Lady Charlotte Guest, Victoria Owens, has written the following article.

Although nineteenth century industry relied heavily upon steam power, people were slow to recognise the dangers that it presented. In 1836, an accident occurred at Dowlais which showed just what elemental peril high pressure steam could present. Dowlais House, home of ironmaster Josiah John Guest and his family, stood on the very margin of the Dowlais Ironworks and in her journal Guest’s wife Lady Charlotte wrote a graphic account of the boiler explosion that took place one November morning.

An excerpt of the 1851 Public Health Map showing the proximity of Dowlais House to the Ironworks

Guest had risen early. His nephew Edward Hutchins hoped shortly to purchase a share in Thomas and Richard Brown’s Blaina Iron Company and the two men planned to visit the Browns’ Works on the Ebwy fach riverin the course of the day. Charlotte got up while her husband was breakfasting, and as she dressed, she distinctly felt the house tremble. At first, it reminded her of what she had read about earthquakes – not a phenomenon of which she had any direct experience – and she reasoned that ‘something – not perhaps very awful – must have happened at the works.’ Hearing a window rattle she assumed, undaunted, that her fourteen-month old son Ivor was amusing himself by shaking it.

A vast explosion, the crash of a falling stack and the sound of bricks cascading onto the roof of the house disabused her of her error, and hearing the sound of escaping steam, she guessed that a boiler had burst. It was, she realised, ‘the centre one of the New Forge Engine, and consequently very near the House, towards which all the fury of the explosion was directed.’ While it was not unusual for eighteenth and early nineteenth century industrialists to live close to their works, 1836 plans of the Dowlais Works show the New Forge with its engine actually bordering the gardens of Dowlais House which was left ‘strewn with bricks, cinders and broken glass.’ Amazed and appalled, Charlotte later found a brick in her bed and discovered a heavy piece of iron ‘weighing several pounds’ embedded in an internal wall. Apparently it had passed straight between two servants as they chatted in the first-floor corridor. Meanwhile, a couple of workmen on the charging platform by the furnaces had an equally lucky escape. According to Charlotte, a ‘steam pipe fell between them and the furnace they were charging upon the bar they were using, which it knocked out of their hand.’ If the sentence-structure is somewhat awkward, it may reflect her shock at recalling how she saw the projectile strike the bar used to thrust coke, ore and flux into the furnace mouth clean out of the men’s hands. George Childs’ 1840 depiction of Dowlais labourers gives an idea of the impact that the sight must have made on her. ‘Most thankful I was,’ she wrote later, ‘that we were all in the house together. Had Merthyr [her private name for her husband] been in the works (which he would have been a quarter of an hour later) my alarm would have been infinitely greater.’ Caught in the blast, the boiler stack seemed to rise from its base to pause, ‘as if poised,’ in the air before crashing down from its 120 foot height across the Guests’ lawn, breaking all their windows’ and killing a man and a boy as it fell..

Outside her bedroom, Charlotte found Susan the nursemaid with young Ivor in the passage. As they ran downstairs in search of John, they felt the whole building shake. John was, in fact, already hastening upstairs to look for them and husband and wife simultaneously realised, appalled, that neither of them knew what had happened to their two-year old daughter Maria. Charlotte thought she had been eating an early breakfast with her father while John, in the stress of the moment, could not remember what he had done with her or whether she had even been with him. After a few moments of numb alarm, they found the little girl safe with the housekeeper, neither hurt nor unduly frightened. Seeing a crowd surge across his garden John went out to comfort them as best he could, before seeking to assess the extent of the damage to the works’ buildings.

The following week’s edition of the Cardiff and Merthyr Guardian carried not only a report of the explosion but also a comprehensive description of the boiler. A new installation, it was apparently 42 feet long and 6 feet in diameter. Despite weighing 18 tons and being embedded in solid masonry, it had burst with enough force to thrust it clean off its foundation and carry it over some ten yards’ distance before coming to rest at right-angles to its original position. A large piece of flying masonry had hit a house nearby, home to seven people. The man who had been sleeping in the room into which it actually landed somehow avoided injury, but not all the inhabitants were so lucky. John Howe, a fireman, and the boys David Thomas and John Jones both lost their lives, while ‘the wife of Daniel James, founder’ was badly injured. Meanwhile the New Forge where the boiler had been located, was blown to smithereens – ‘damage’ which the newspaper estimated at not less than £1000, ‘without taking into account the loss occasioned by the suspension of the works.’

At the inquest following the explosion, the jury returned a verdict of accidental death upon the deceased. Significantly, the coroner explicitly ruled out any question of culpability on the part of the Dowlais Company’s chief engineer John Watt. Local opinion – and presumably Watt himself – linked the cause of the explosion to the rupture of a boiler-plate immediately over the fire. The Dowlais Company’s decision in 1838 to name a new plateway locomotive ‘John Watt’ may well reflect the esteem in which John Guest held his colleague.

Merthyr’s Chapels: Horeb Chapel, Penydarren

Horeb Welsh Independent Chapel, Penydarren

The cause at Horeb was begun in 1837 by Rev Joshua Thomas, the minister of Adulam Chapel in Merthyr. Rev Thomas started a school in a room adjoining the Lucania Billiard Room in Penydarren, and several members of Adulam, who were living in Dowlais, met Rev Thomas in the school and started holding prayer meetings there. The congregation grew to an extent that it was decided to build a new chapel, just a few yards away from Joshua Thomas’ school. The foundation stone was laid on 1 August 1839, and the chapel, the first place of worship in Penydarren, was completed the following year at a cost of £700. The original chapel was built in an elevated position overlooking the High Street.

For the first few years, Horeb was in a joint ministry with Adulam with the Rev Joshua Thomas ministering to both chapels. However when Rev Thomas left Merthyr in 1843, the elders of the chapel decided to call their own minister, and Rev Evan Morgan was ordained on March 26-27 1844. Sadly Rev Morgan was a victim of the cholera epidemic and died in June 1849, and he, his wife and one of his children were buried on the same day.

As a result of the cholera epidemic, there was a religious revival in Wales with many people joining chapels and churches. The congregation at Horeb continued to grow and in 1853, a new chapel was built at a cost of £1100. The new chapel was built with the main entrance now facing Horeb Street. Within three years a new schoolroom was also built next to the chapel at a cost of £400.

In 1891, the fabric of the building was in need of some attention, so the chapel underwent minor renovations and a new pulpit and ‘Big Seat’ were erected at a cost of £330.

By 1908, it had become obvious that the chapel was becoming quite dilapidated and really not adequate for the congregation, so a new chapel was built in 1908/09 at a cost of £3,900, including £400 for a grand pipe organ.

The magnificent third Horeb Chapel.

The interior of the chapel was finished to a very high standard with magnificent plasterwork, and the gallery and pulpit made from a mixture of oak, pitch pine, mahogany and ebony. The new chapel was considered to be one of the finest chapels in South Wales.

On the night of 28 April 1973, an arsonist started a fire in the chapel, and the building was gutted. Only the vestry adjoining the chapel was saved, and also the iron name plate which was cast in the Dowlais Ironworks.

Following the fire the chapel had to be demolished and the decision was made to build a new chapel. A new modern chapel was built at a cost of £60,000. Horeb is now the only place of worship in Penydarren.
