In Search of the Dowlais Railway

by Victoria Owens

When the Taff Vale Railway between Merthyr Tydfil and Cardiff received its authorisation in 1836, the Act gave the Railway Company leave to construct a branch to the tramroad at Dowlais. For various reasons, the Railway Company procrastinated over the work, with the result that the Dowlais Iron Company eventually took responsibility for making the Branch themselves. The terms of the 1849 Dowlais Railway Act authorised them to build not only the line, but also a passenger station, situated close both to the Iron Works’ lower entrance gate and the Merthyr-Abergavenny road.

Sir John Guest

Although the 1849 Act allowed the Iron Company five years to complete the railway, it was in fact ready in three. Financed by Sir John Guest, MP for Merthyr Tydfil, promoter of the TVR and soon to be sole partner in the Dowlais Iron Works, at a mile and sixty-eight chains in length, the steep gradient of its route up Twynyrodyn Hill meant that its lower part operated as an inclined plane. The Newcastle firm of R & A Hawthorn designed a stationary engine capable of drawing trains of up to six carriages in length and 33 tons in weight over s distance of 70 chains and 30 links, up the 1 in 12 slope. It had two horizontal cylinders of 18 inch diameter and 24 inch stroke and worked at 50 strokes per minute. The steam pressure was 30 lbs psi.

Viewing its erection in March 1851, a local newspaper drily enquired whether in ten years’ time, a ‘chronicler of local events’ might have reason to report the completion of a notional line ‘from Dowlais to the extreme point of Anglesey.’

Modest it might be, but at the Dowlais Railway’s official opening in August 1851, Royalty graced the ceremony. Three days before the event, just as Sir John and his wife Charlotte were about the set off on a carriage drive, the horse-omnibus drew up outside their home, Dowlais House, bringing Charlotte’s cousin Henry Layard, known as ‘Layard of Nineveh’ on the strength of his recent archaeological discoveries in Assyria, and with him, his friend Nawab Ekbaled Dowleh, whom the newspapers called the ‘ex-King of Oude.’

With the help of Works Manager John Evans, Charlotte organised every stage in the celebration, from welcoming a party of Taff Vale Directors who had travelled down from Cardiff for the occasion, to pairing up her ten children to walk in the procession: ‘viz. Ivor and Maria; Merthyr bach and Katherine; Montague and Enid; Geraint [Augustus] and Constance; Arthur and little Blanche.’ Flanked, probably as much for show as for protection, by the local police, they made their way to the station, decked with greenery for the occasion, with the school-children and company agents following. The ‘trade of Merthyr and Dowlais’ joined them along the way, all to the accompaniment of music from the combined bands of Cyfarthfa and Dowlais.

From Dowlais station, the passengers travelled to the top of the incline where their locomotive was uncoupled. Messrs. Hawthorn’s engine lowered the carriages down the slope, and the intrepid travellers made their way on to Merthyr. Some of them chose to continue by TVR to Abercynon, but the Guests and their visitors preferred to return to Dowlais.

Later in the day, a ‘small party comprising about five hundred ladies and gentlemen’ enjoyed a sumptuous meal at the Iron company’s Ivor Works, to be followed by speeches and dancing. Sir John, whose health was none too good, left the festivities early but Charlotte remained on hand to propose the healths the Directors of the Taff Vale railway and to open the dancing with Rhondda coal owner David William James as her partner. With Layard as his interpreter, the Nawab set the seal upon the day’s pleasures by expressing his delight at the hospitality that he had received in Dowlais and asserting that he had never enjoyed himself so much as he had during his ‘brief sojourn’ in Wales.

Although Sir John envisaged the Dowlais Branch primarily as a mineral line, he seems to have been perfectly happy with the requirement that it should also accommodate passenger traffic. Records indicate that over 1853,it came in for usage by 755 first class, 1884 second class and 7253 third class passengers but, sad to say, disaster struck at the end of the year. December 1853 witnessed an ugly accident when a passenger carriage over-ran the scotches to hurtle down the Incline unchecked and two passengers lost their lives, with five more suffering serious injuries. Officially speaking, passenger traffic on the railway ceased in 1854.

Unofficially, as Merthyr Tydfil writer Leo Davies would explain, it was usually possible – given a combination of unscrupulousness and agility- to obtain a lift. In an article of 1996, he described the whole unorthodox procedure in graphic detail. Access was obtained via the wingwall of a bridge and through some railings. The sound of the hawser gave advance warning of the approach of a train on the incline – ‘four ballast trucks, each half-filled with sand.’ Travelling typically at ‘a nice, sedate trotting pace’ there was evidently ample scope for the non-paying passenger to grasp the outside rim of the buffer, and ‘swing both legs up and around the buffer spring housing.’

The Dowlais Railway closed finally in 1930 and the trackbed would be filled in sixteen or so year later, over 1946-7. In the 1990s, when Leo Davies reminisced about the ‘Inky’ as he fondly calls it, the ‘straight, green, grass grown strip of land’ ascending Twynyrodyn Hill remained visible. Perhaps, with the eye of knowledge or faith it remains so. Admittedly, former pupils of Twynyrodyn School remember the old line’s route, but without local knowledge it is not easy to trace. Only a few yards of broad green path survive to mark the site – perhaps – of the old trackbed and the name ‘Incline Top’ given to a hamlet at the edge of a plateau of rough ground extending towards Dowlais and its great Ironworks commemorate the location of Sir John Guest’s last great enterprise.

The Church of St. John the Baptist, Dowlais 

by Carolyn Jacob

The Church of St. John the Baptist, Dowlais was built in 1827, and it is likely that the Dowlais Church was named after its founder and benefactor, Josiah John Guest, iron-master of Dowlais and known as Sir John Guest.

Although brought up a strict Wesleyan Methodist he decided that the religious welfare of the workmen called for a church in Dowlais and that the industrial success of Dowlais called for the establishment of Dowlais as a Parish in its own right. Guest paid £3,000 towards the cost of the building and it was consecrated and opened on 27 November 1827 by Dr Sumner, Bishop of Winchester and former Bishop of Llandaff.

Lady Charlotte Guest presented the Church with its Communion vessels and Sir John Guest contributed generously to the maintenance of the clergy at Dowlais; he also supported many chapels in the area. Sir John died in Dowlais on the November, 1852 and a plain Italian marble slab at the top of the Chancel steps still marks where he is buried in St John’s Church. A massive marble columned tablet is inscribed with his epitaph. St. John’s Church thrived and held two services each Sunday, two services in English and also two in Welsh and so it catered for both languages.

The original Church was a plain, simple, square building with tall windows and a square tower. Gradually the Church has been extended, rebuilt and enlarged.

During the 1890s the main Nave was rebuilt with additions to the aisles to allow room for the growing congregation and enable 800 sittings.The Church was restored at a cost of £4,500 under the direction of the architect E.A. Johnson, who later designed the Merthyr Tydfil Town Hall. Most of the expense was paid by Lord Wimborne, eldest son of the founder Sir John Guest; although a great bazaar in Dowlais raised £1,000 which was a huge amount in those days. The new extended aisle was the gift of Edward Pritchard Martin, General Manager of the Dowlais Iron Company in memory of his father George Martin.

This family also financed the splendid decorative ‘Miner’s Window’ in the Church which show two coal miners digging at a coal face with the caption underneath, ‘The Thing that is hid Bringeth he forth light’. Such an industrial motif in stained glass is quite unusual to be found in a Church.  The bare headed miners, with their picks, candles, and their clothing and boots, present an accurate image of a coal miner (see right).

The interior of St John’s is imposing because of its sheer size. The tall fine oak roof of the Nave is a hammer beam type, supported by 6 larger and 5 smaller corbel tables on each Nave wall. The interior walls are double thick yellow brick. The five plain Early English styled columns with rounded bases can still be seen inset to the new west Nave wall.

The Martin family had charge of the Collieries for the Dowlais Works and the American singer, Donny Osmond, claims descent from this famous Dowlais family, whose Brass plaques and monuments are still in the Church. The enlarged and redesigned Church was opened officially in October 1894 with a special service.

The present Church is a fine structure of Llancaiach blue pennant stone, after the Gothic style of the 13th and 14th centuries.  This wonderful Gothic church has long been a central land mark in Dowlais and has changed little since the late nineteenth century, although the former vestry has been demolished.  St John’s Church is 112 feet in length, with a maximum width of 84 feet and about 60 feet high. The whole construction is of masoned Pennant stone, but the doors and windows are surrounded with lighter coloured ashlar blocks of Forest and Bathstone trimmed with dripstone and moulds. This magnificent church was always perhaps too large for its congregation in this most non-conformist of towns.

Far less than 10% of the population here attended an Anglican Church. In our more secular times in proved to be too large for its Dowlais Congregation and it closed in 1997. The church is currently undergoing conversion to residential flats which will retain its original fine structure.

Merthyr’s Chapels: Hermon Chapel, Dowlais

We continue our feature on the chapels of Merthyr with a look at one of the oldest and largest chapels in Dowlais – Hermon Welsh Calvinistic Methodist Chapel.

In 1791, an elderly lady named Mary Taylor moved to Dowlais from Dinas Powis, but upon arrival in Dowlais she found that she was the only Methodist in the area. She was soon joined however by a Mr Thomas Davies, and they started worshipping together. Gradually, others joined them, and they began worshipping at Pontmorlais Chapel in Merthyr before they were given permission to meet in Dowlais on the premises of Mr Thomas Williams, a local shoemaker.

As the congregation grew, they decided, in 1806, to open a Sunday School, and in 1810 they formed themselves into an established cause. The worshippers continued to meet in private houses until they took out a lease on the small Bethel Chapel; the Baptist Cause that had started there having failed.

The congregation continued to grow and in 1827 they decided to build their own chapel on a plot of land acquired at the bottom end of Gwernllwyn Isaf Farm. This was the first chapel of any importance to be built in Dowlais.

In 1837, the freehold of the land on which the chapel was built was purchased from Mrs Mary Overton, and it soon became apparent that chapel was too small to accommodate the ever growing accommodation. A new chapel was designed by Rev Evan Harris, minister at Pontmorlais Chapel, and the very large new chapel was completed at a cost of £2,000 and opened in 1841.

The interior of Hermon Chapel

It is interesting to note that  Josiah John Guest, owner of the Dowlais Ironworks, and a staunch Anglican, contributed £50 to the rebuilding of the chapel. The reason he gave was that he was pleased to hear that none of the congregation had participated in the Chartist Riots.

Hermon Chapel was subsequently regarded as one of the most important Calvinistic Methodist Chapels in Wales and became the mother church of Libanus Chapel, Calfaria Chapel, Elizabeth Street Chapel and Radcliffe Hall, Penydarren, as well as being prominent in the founding of Nazareth, Fochriw; Ysgwydd Gwyn, Deri and Gosen, Bedlinog.

The magnificent Nicholson organ in Hermon Chapel

In 1901 a new school room was built adjoining the chapel at a cost of £1,000, and in 1904 major renovations were undertaken costing £3,000, including £600 for a magnificent pipe organ built by Messrs Nicholson and Lord of Walsall.

With the redevelopment of Dowlais, the chapel was forced to close and in 1962, became the first of Dowlais’ chapels to be demolished.

The Taff Vale Railway

In 1835, the major industrialists in Merthyr began considering building a railway line from Merthyr to the Bute Docks in Cardiff. To this end, Anthony Hill, owner of the Plymouth Ironworks, contacted Isambard Kingdom Brunel, to estimate the cost of building such a railway – Brunel replied quoting an estimate of £190,649. The industrialists subsequently held a meeting, chaired by Josiah John Guest, at the Castle Inn in Merthyr, to discuss the issue, and decided to request Parliamentary permission to form a company to build the railway. Permission was granted an the company was incorporated the following year.

On 21 June 1836 Royal Assent was given to The Taff Vale Railway Company’s Act, allowing for the creation of the Taff Vale Railway Company. The founding capital of the Company was fixed at £300,000, in £100 share units. The directors were Josiah John Guest, Walter Coffin, Edward Lee, Thomas Guest, Thomas Guppy, Thomas Powell, Christopher James, Thomas Carlisle, Henry Rudhall, William Wait, William Watson, and Peter Maze. Company profits were capped at 7% originally, with a clause allowing for an increase to 9% subject to a reduction in the rates and tolls charged for use of the line.

The Act also capped the speed of the trains on the line to 12 mph (19 km/h), with stiff penalties for any speeding.

Construction of the railway was started in 1836, and the stretch from Cardiff to Navigation House (later named Abercynon) was opened in a formal ceremony on 9 October 1840, with public services starting the next day. The stretch from Abercynon to Merthyr was opened on 12 April 1841. The railway was single-line for its entire length, with passing only possible at or near the stations. It was not until 1857 that it became a double line. Brunel, the chief engineer, had chosen a narrower gauge (4 feet 8.5 inches or 1.435 m) than the 7 foot (2.134 m) gauge he would later choose for his Great Western Railway in order to fit the railway into the narrow space allowed to him by the River Taff valley.

Construction of the main line was relatively straightforward. The line mostly followed the course of the valley, and therefore needed few bridges and no tunnels. Brunel designed an impressive skew stone arch viaduct at Pontypridd, which spanned 110 feet (34 m) over the River Rhondda; the viaduct is still in use today, although it has been supplanted by a second, parallel viaduct. A similar viaduct was built at Quakers Yard.

The TVR’s original station in Merthyr was at Plymouth Street and was opened on 12 April 1841.

This was joined in 1853 by the High Street station of the Vale of Neath Railway. A short joint line (TVR and GWR) was built to connect the TVR line to the new station in 1877. A year later, in August 1878, the Taff Vale transferred all of its passenger services to the High Street station, and used Plymouth Street as a goods depot instead. High Street station thus became the only passenger station in Merthyr, and was used by a total of six separate companies prior to the 1923 grouping. The TVR also opened stations at Merthyr Vale in 1883 and Pentrebach in 1886.

The main line of the TVR was 24 miles (39 km) long. However, no fewer than 23 branch lines took the full length of track to 124 miles and 42 chains (200.40 km). Many of those branch lines were smaller lines taken over by the TVR – in 1841 a branch line was opened in the Rhondda going as far as Dinas, and a second was opened to Llancaiach Colliery. The Rhondda line would subsequently be extended, and by 1856 it had been extended into two lines – one to Maerdy and the other to Treherbert.

The TVR proved its worth immediately. At its peak, two trains a minute passed through the busiest station, Pontypridd. By 1850, the TVR was carrying 600,000 tons (600,000 metric tons) of coal per annum, and was paying a 6% dividend.

The line was conceived as a goods line, carrying iron and coal. However, it also ran passenger services from the beginning. There were two passenger trains each way daily, including Sundays. This was extended to three weekday services in 1844. Single fares from Cardiff to Merthyr were 5 shillings for first class, 4s. for second class, and 3s. for third, and were each reduced by a shilling in 1845.

The Taff Vale Railway continued to operate as a company in its own right until it was incorporated into the Great Western Railway in 1923.

The current railway line between Cardiff and Merthyr now follows the route of the original Taff Vale Railway.

Quakers Yard Viaduct – an addendum

Following on from yesterday’s article about Quakers Yard Viaduct, historian Victoria Owens, a regular contributor to this blog has sent the following fascinating observation.

Lady Charlotte Guest, found the viaduct a source of total wonder and delight. In her journal entry for 25 October 1839 she describes a visit to the site while the bridge was under construction. It sounds as though John Guest was keen to show it off to a party of his friends, which included Edward Divett MP (he would be one of the trustees appointed to run the Dowlais Ironworks on Josiah John Guest’s death) and his fragile-sounding wife. Charlotte writes:-
When the carriages had reached that point of the turnpike road nearest to the viaduct, we got out and walked to it. There was more scrambling to get there than some of the ladies liked – We crossed by the scaffolding as I had done before & all the party went back over it in the same way except Merthyr and myself and we went over the bridge itself, scrambling over the rough masonry. – Three of the six arches were not closed and in these places we had planks thrown down across for us & I believe I was the first female that ever crossed this bridge, and at the height of some 70 or so feet it appeared a perilous undertaking thought it was not really so . The expedition fatigued Mrs Divett so much that she was not able to dine with us, which the men regretted, as we had a very pleasant evening and had some singers to entertain us with welsh songs.

Dowlais Stables – an additional comment

Many thanks to Victoria Owens, a keen supporter of this blog for the following piece that she sent as a comment on my previous post. As it is so interesting I thought it was worth sharing with everyone and deserved a post in its own right.

In January 1835, following Josiah John Guest’s return – unopposed- as Merthyr Tydfil’s MP, he and Lady Charlotte hosted a ball in the granaries above the Dowlais stabling to celebrate. Charlotte organised the decorations, which included patriotic transparencies proclaiming ‘W.R.’ [William Rex] and EGLWYS Y BRENEN [Church and King] drawn by the clerks from the ironworks office and hung where they caught the light. Josiah John’s Arms -‘with a Lyre and a fleur de lys’ according to the Merthyr Guardian, but when had he acquired the right to an heraldic device? – were chalked on the floor. The Rev Evan Jenkins, Rector of Dowlais, lent the Guests the church chandeliers, evergreens bedecked the walls and the band of the Cardiff militia provided music. The local gentry, whether or not they shared Guest’s political views, came in anticipation of a good party. By all accounts, the weather was vile, with thick snow delaying the London mail coach. In consequence, the local paper had much fun at the expense of a party of urban sophisticates who arrived too late for the fashionable quadrilles and had to make do with country dances ‘like Sir Roger de Coverley and Boulanger’.

(Information from the Cardiff and Merthyr Guardian, Glamorgan, Monmouth, and Brecon Gazette, Saturday 24 January 1835 and Lady Charlotte Guest, Extracts from her Journal, ed. the Earl of Bessborough (John Murray: London, 1950, pp 37-38, 19 – 20 January 1835).

Dowlais Stables

One of the oldest and most impressive buildings still standing in Merthyr is Dowlais Stables.

In the early part of the Nineteenth Century, despite Merthyr being at the forefront of the industrial revolution, and indeed pioneering the first steam-powered locomotive in 1804, Dowlais (and all the other) Ironworks were reliant on horses and ponies to bear the brunt of the heavy haulage work. In July 1819, it is recorded, Michael Faraday the eminent scientist visited the Dowlais Works, and walked with Josiah John Guest to the hay fields near the Works where the hay made there was used to feed the 150 or so horses which the Dowlais Iron Company used.

The following year, Josiah John Guest had stables built to house the horses. The architect of the building is unknown, but it was (and still is) a striking building. The complex is of symmetrical design, in the form of a rectangular plan of ranges set round a (formerly railway-served) central yard. The façade has two-storeys with centre and end pavilions separating 9-bay ranges and there is a tall central arch, through which the railway passed, with a circular clock face. This façade is roughly 450 feet long, and the central block rises to over 50 feet, with the central arch being roughly 30 feet high. This is topped with a decorative wooden cupola.

A plan of the layout of Dowlais Stables

It is said that when the stables was built, a number of contemporary newspaper cuttings, and several items of memorabilia were hidden behind one of the arch stones to be revealed “when the building falls down”.

The stables were well used; towards the end of the nineteenth century, the Dowlais Iron Company were employing “over a dozen blacksmiths, several stable lads and a score of other hands to tend the several hundred head of horses now owned by the Company and stabled in the very heart of Dowlais”.

As well as being used as for stabling horses, soldiers were stationed in the building for several years after the Merthyr Riots of 1831. Also, of course, Lady Charlotte Guest famously used the large first-floor rooms as a boys school until Dowlais Central Schools were opened in 1854-5.

The stables closed in the 1930’s and the complex became derelict; in the late 1970’s unauthorised demolition was started, but was brought to a halt. The site was subsequently bought by the Merthyr Tydfil Heritage Trust in 1981, and despite the façade partially collapsing in 1982, the building was eventually rebuilt as flats; the south east facade walls were also substantially rebuilt. Of the original structure, only the southeast range and Stables House on the north west range currently survive.

James Neilson’s Hot Blast: Pierre Armand Dufrénoy and Lady Charlotte Guest – part 2

by Victoria Owens

In September 1836 advertisements for On the use of hot air in the Ironworks of England and Scotland […] appeared in the London newspapers. Published by the august firm of John Murray, it was a modest octavo, priced at 5s 6d. To all appearance, the English text was anonymous, the title page stating only that the work was ‘Translated from a report made to the director-general of mines in France, by M. Dufrénoy in 1834 [sic]’ without naming the translator. The entries in John Murray’s ledgers were equally uninformative about the origin of the English version, referring to the work only as ‘Hot Air (On the use of)’ with a caret mark adding the scribbled note ‘By M. Dufrénoy’. The illustrations, however, carry some mark of Lady Charlotte’s involvement. Murray’s publication re-cycles the engravings which had appeared in Dufrénoy’s Rapport, but with an addition. Examination of the English text reveals the initials ‘C.E.G.’ – Charlotte Elizabeth Guest – in her distinctive handwriting beside each picture, presumably as confirmation to the printer that the image is to be bound in with the text.

Illustration of the Dundivan Heating Apparatus from On the Use of Hot Air in the Iron Works of England and Scotland […] (London: John Murray, 1836). The initials ‘C.E.G’ and date ‘March 1836’ appear below the engraved diagram.
To remain anonymous may have been her choice. Not only were mid-nineteenth century publishers apt to view women writers dismissively – it was why the Bronte sisters took masculine pen-names – but her mother had been less than happy about her marriage. For all his acumen, the industrialist John Guest was not the husband she would have chosen for her daughter – she preferred Robert Plumer Ward, a barrister-cum-novelist, whose proposal Charlotte resolutely declined. Charlotte, what was more, had loved South Wales from her first sight of the ‘blazing furnaces’ of Dowlais and the ‘broad glare of the fires.’ By contrast, when Lady Lindsey visited in August 1834, she thought the Glamorganshire countryside ‘wild enough for banditti’ and likened the ironworks to ‘a den of thieves.’ It seems unlikely that she would have viewed her daughter’s work on the Rapport sur l’emploi de l’air chaud with much enthusiasm. Nevertheless, Charlotte’s achievement did not remain secret for long. In December 1836 the local newspaper jubilantly identified her as the translator of On the Use of Hot Air and carried a story full of praise for her disregard of all ‘temptations to indolence’ and ‘frivolities of fashion,’ and ready devotion of her ‘time and talents to useful […] works by which mankind may be benefitted, and the interests of Science advanced.’

Her book had a print run of only two hundred copies but in iron manufacturing circles, it sparked considerable interest. On 1 October 1836, when it had been out for less than a month, John Wilson, co-proprietor of the Clyde Ironworks and member of the syndicate which held the patent rights to the Hot Blast process, called on Lady Charlotte to request a copy of her translation. He was apparently ‘anxious to see [it], as he did not understand French.’

If it yielded little financial return, the engagement with Dufrénoy’s survey of the British iron trade nevertheless set the course of Charlotte’s future. It is no coincidence that in her journal entry for 26 September 1836 – just when the book went on sale – she should mention having ‘undertaken the office of Merthyr’s secretary, to write all his letters and keep them copied and arranged.’ It was, she thought, a ‘beginning in earnest’ for which she had ‘been training for some time.’ Her remarks were prescient indeed, for on John’s death in 1852, she succeeded him as head of the works, and would soon have to bring all her acuity to bear on resolving a strike. Disputes aside, commerce gave her immense satisfaction. ‘I am happy to see we are at the head of the iron trade,’ she wrote in April 1839. ‘Otherwise I could not take pride in my house in the City, and my works at Dowlais, and glory (playfully) in being (in some sort) a tradeswoman.’

James Neilson’s Hot Blast: Pierre Armand Dufrénoy and Lady Charlotte Guest – part 1

by Victoria Owens

Many thanks to Victoria Owens who provided the following fascinating article.

When James Beaumont Neilson, engineer of the Glasgow gas works, patented his ‘hot-blast’ of 1828 – the system of pre-heating air by passing it through a hot ‘vessel or receptacle’ before it entered the blast furnace – he was confident that it would save fuel and reduce costs. Encouraged by three Scots iron manufacturers – Colin Dunlop of Tollcross, Charles McIntosh of Crossbasket, and John Wilson of Dundyvan, all of whom acquired shares in his patent rights – Neilson conducted  experiments at the Clyde Ironworks which demonstrated that use of the hot blast could reduce fuel consumption by about a third. News of its merits spread fast. Not only did many English, Scots and Welsh ironmasters adopt Neilson’s system, but the French inspector of mines, Ours-Pierre-Armand Petit-Dufrénoy, (1792-1857), visited Britain to analyse the economic and metallurgical consequences of its application.

Ours-Pierre-Armand Petit-Dufrénoy

Dufrénoy’s Rapportsur l’emploi de l’air chaud dans les mines à fer de l’Ecosse et de l’Angleterre’ appeared in the 1833 issue of the French Annales des Mines. By chance, Edward Hutchins, nephew of Josiah John Guest of the Dowlais Iron Company, obtained a copy, in autumn 1834 and, recognising the British iron trade’s likely interest in its content, asked his uncle’s wife Charlotte to translate it into English.

The previous year, John Guest had married Lady Charlotte Bertie, daughter of the late ninth earl of Lindsey. An able linguist, she was fluent in Latin, Greek, Persian, Arabic and Hebrew. Soon after her marriage, she began to learn Welsh from the Revd. Evan Jenkins, Rector of Dowlais, and would in time publish a best-selling translation of the mediaeval Welsh story-cycle known as the Mabinogion. That she had a fair working knowledge of French goes without saying.

She started work on her translation of Dufrénoy’s article on 3 December 1834, while John Guest, MP for Merthyr Tydfil, was canvassing votes for the coming general election. She found the text ‘full of technicalities’ and foresaw that producing an English version would take a long time. Nevertheless, she continued throughout the following day, and calculated that by the evening, she had completed about a sixth of it. Here, to give some flavour of the task, is Dufrénoy’s description of Neilson’s methods:- ‘Dans la première experience,’ he writes

l’air fut chauffé dans une espèce de coffer rectangulaire en tôle de 10 pieds de long, sur 4 pieds he haut et 3 de large, semblable aux chaudières des machines à vapeur. L’air provenant de la machine soufflanteé tait introduit dans cette capacité, oùil s’échauffait avant de sa render dans le haut-fourneau. Malgré l’imperfection de ceprocédé, qui ne permit d’élever la temperature de l’air qu’a 200⁰ Fahrenheit (93.3 cent), on pouvait déjà pressentir que l’idée de M. Nielson était destinée à produire une revolution dans le travail du fer.

‘In the first experiment,’ offers Lady Charlotte, ‘the air was heated in a kind of rectangular box of sheet iron, ten feet long, four high and three wide, similar to the boilers of steam engines. The air proceeding from the blowing machine was introduced into this space, where it was heated, previous to being conveyed into the blast furnace. Notwithstanding the imperfection of this process, which did not admit of the air being heated above 200⁰ Fahr, it became immediately apparent that Mr Neilson’s idea was destined to produce a revolution in the manufacture of iron.’

If terms such as tôle [sheet metal] and chaudières [boilers] sent her to the dictionary, her rendition of the idiomatic phrase on pouvait  déjà pressentir, [literally, ‘one could already foresee’] as ‘it became immediately apparent…’ shows her ready command of the syntax.

First caught up in the excitement surrounding the election and, later, dismayed by an outbreak of cholera, Charlotte does not mention the hot blast again in her journal until February 1835. By this time, she and John and their infant daughter Maria were visiting Charlotte’s mother and step-father at their Lincolnshire home – Uffington House near Stamford. ‘Wet Day,’ Charlotte wrote on Friday 13 February; ‘Merthyr (her private name for her husband) […] corrected iron hot air [sic] for me.’

For all its brevity, her statement raises intriguing questions. That John Guest should have been interested in the observations of a highly qualified mining engineer from a rival nation upon the production process of every ironworks from Calder to Merthyr Tydfil by way of Monkland, Codnor and Wednesbury was understandable. Whether he also wished to explore Dufrénoy’s account in the hope of discovering some means of using the hot blast technique without having to pay Neilson royalties is a matter for speculation. The fact that on 12 March 1836 an injunction was issued against Guest and partners restraining them from infringement of Neilson’s patent suggests that by the time Lady Charlotte was translating the French treatise, the Dowlais Ironworks had already introduced the hot blast. In the event, John Guest, was quick to settle with Neilson and his fellow patentees, and pay the shilling-per-ton royalty on iron produced by their method.

Furthermore, Lady Charlotte’s reference to her husband’s ‘correction’ of her work, suggests that, rather than treat her translation of the treatise as a work of private reference, the two of them thought it deserved publication. Certainly the English edition of On the use of hot air includes a number of observations – each designated ‘Note by the Translator’ –which, to judge from their detailed knowledge of the ironworks and coal deposits of South Wales, are the work of an industry insider. The remark, for instance, that before they introduced the hot blast, both Guest at Dowlais and Samuel Homfray of the Penydarren ironworks were using raw coal rather than coke to fuel their furnaces evinces considerable local knowledge. Incidentally the concluding ‘Note by the Translator’ not only gives a complete overview of the hot blast apparatus in use respectively at Dundivan in Scotland and Pentwyn, Clydach and Dowlais in Wales but also appraises the efficiency of the system and the quality of the iron produced in each place. Dufrénoy includes no corresponding commentary and this state-of-the-art survey of British iron manufacture offers an authoritative epilogue to the English version of his treatise.
