Merthyr Tydfil in 1803 – part 3

From: The Scenery, Antiquities and Biography of South Wales, from material collected during two excursions in the year 1803. Volume 1, by Benjamin Heath Malkin (1807)

Pages 268 – 272

In such a review of the increasing wealth and population, which these important manufacturers are yearly conferring on the country, we may well exclaim with Jago,

Hail, native British ore! of thee possess’d,
We envy not Golcenda’s sparkling mines,
Nor thine, Potosi! nor thy kindred hills,
teeming with gold. What! though in outward form
Less fair? not less thy worth. To thee we owe
More riches than Peruvian mines can yield,
Or Montezuma’s crowded magazines
And palaces could boast, though roof’d with gold.

This town, as it may properly be termed, is now by far the largest town in the whole principality. Its population, in the year 1802, was found to be upwards of 10,000; and it is supposed that it amounts at this time, December 1803, though at the interval only one year from the date of the numeration to considerably more than 11,000; and this is to be understood without the including the suburbs, as we made denominate it correctly enough, of Coed y Cymmer, on the Breconshire side of the River, the population of which is at least 1,000. Swansea, heretofore the largest town in Wales, exceeding every other town by at least 1,000 inhabitants, is now nearly, if not quite, doubled by Merthyr Tydfil. It is true, external appearance of Merthyr Tydfil is not to be compared with that of Swansea.

The House of Mr. Homfray at Penydarren is large and elegant, with fine and well planted gardens, greenhouses, hot-houses, and all the accommodations befitting the residence of a wealthy family: but the splendours of Merthyr Tydfil begin and end with this mansion. When the first furnaces and forges were erected, there could not exist the slightest glimmering of prescience, that this little obscure Welsh village would, in less than 40 years, grow up to such a magnitude, as to be far more populous than any other town in Wales.

The first houses that were built were only very small and simple cottages for the furnacemen, forgemen, miners, and such tradesmen as were necessary to construct the required buildings, with a common laborers who are employed to assist them. These cottages were most of them built in scattered confusion, without any order or plan. As the works increased, more cottages were wanted and erected in the spaces between those that had been previously built, till they became so connected with each other, as to form a certain description of irregular streets, very much on the plan of Crooked Lane in the City of London. These streets are now many in number, close and confined, having no proper outlets behind the houses. They are constantly very filthy for the most part, and doubtless very unhealthy. Some streets, it is to be observed, have within these few years being built, and more are building, on a better plan; in straighter lines, and wider, having decent houses, with commodious outlets, and other necessary attentions to cleanliness and health.

In some of the early, and rudely-connected streets, we frequently see the small miserable houses taken down, and larger and very respectable buildings erected in their stead. Such improvements are increasing with some degree of rapidity. Shopkeepers, innkeepers, forge-men, some of them at least, and in no inconsiderable numbers, are making comfortable fortunes, and consequently improving their dwellings. Mr. Crawshay, however, is more conspicuously qualified to set them an example of industry rather than elegance. His house is surrounded with fire, flame, smoke, and ashes.

The noise of hammers, rolling mills, forges, and bellows, incessantly din and crash upon the ear. Bars and pigs of iron are continually thrown to the hugely accumulating heaps that threatened to choke up every avenue of access. It is more humourously than truly said in the neighbourhood, that such scenery is most congenial to the taste, such sounds most lulling to the repose of the owner. The fact however is, that the situation of the Master’s dwelling was fixed long before Mr. Crawshay came into it; and when it is considered how conveniently it lies for the superintendence of the business, few men, brought up in the habits of commercial prudence, would consult agreeable prospects and domestic elegance, at the expense of that best security, the ever-watchful eye of a principal. The machinery of this establishment is gigantic; and that part of it, work by water, among the most scientifically curious and mechanically powerful to which modern improvement has given birth.

The most remarkable piece of mechanism in Merthyr Tydfil is the great water wheel made by Watkin George. Its diameter is 50 feet, and it has the power of 50 horses. It has the advantage of water from above, on its centre, and beneath it; or, in other words, it possesses all the forces of an overshot, breast, and undershot wheel. I apprehend it to be the largest in the Kingdom. Watkin George and William Aubrey, with the two principal engineers, and they are both natives of this country. Watkin George in particular, who planned and executed this immense undertaking, was a common village carpenter. Owing to his success in these mechanical inventions, he got forward by degrees, and became at last so useful to Mr. Crawshay, as to obtain a share in his works. He has lately quitted the concern with from thirty to forty thousand pounds in his pocket. This is one among the most remarkable instances of wealth acquired by the untutored ingenuity of natural faculties.

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.

Reader, take a ride by the Taff Vale Railway from Merthyr to Troedyrhiw, and the locus in quo ought to be recognised.

Mr Henry Kirkhouse was the chief mineral agent at Cyfarthfa, but two of his sons were with him. They resided at Llwyncelyn. Old Mr Wm Williams (known as No 8) was the mechanical engineer; he lived at Pwll Watt. Mr Thomas, the cashier, lived at Nantygwenith Turnpike Gate. Mr Jeffries was the furnace manager at Cyfarthfa, and Mr John Jones was so for Ynysfach. There were some excellent workmen at Cyfarthfa – Saunders, the master moulder of one part and Wm Thomas of the other foundry. The master fitter’s name has slipped my memory, but one of the men, David Charles, can be recalled.

Cyfarthfa was always celebrated for its machinery and engines. Watkin George, the predecessor of Mr Williams, was a man of noted ability; and, as far as known, that reputation is still maintained. George Cope Pearce was the mechanical engineer for a quarter of a century, his predecessor being his brother-in-law, John P Roe. The Williams family were good engineers too.

I forbear to mention some things that can be remembered lest I am prolix, but George Cope Pearce was so original that some two or three things will be stated. His desire for engineering was so strong as to induce his running away from home (his father was the custos of Hereford cathedral), and in coming to Dowlais he enquired for work. Seeing he was not of the class that generally applied, enquiries were made of him, with the result that, while he was hanging on in hopes, his father was communicated with, and came for him; but Sir John (Guest) agreed to take him on after spending some terms at King’s Engineering College. This was done, but his family and friends endeavoured to turn him.

In 1838 he was loco. superintendent at Dowlais; but as was the general rule, he did not get money enough to satisfy him, and went to Messrs Powell at Clydach, near Abergavenny, and engaged in their service. This becoming known, Mr Thomas Evans took him in hand, and by fair promises induced him to write a letter abandoning the idea. Cope could not get the advance expected, and ere three months had gone, Mr Evans began ruling with usual iron rod. They had a few words, and, upon Mr Evans alluding to his having written the letter, heard, “Oh yes; but I forgot to post it”. What followed need not be said. He went to Clydach, and, after a few years, thinking their machinery did not require such a high-priced man, Messrs Powell spoke to him, pointing out what an easy place he had. “Oh then you want a smash or two, I suppose. Well, I daresay that can be arranged, if you wish”. Do not think this is untrue, for it is a fact.

He left Clydach some years ago and came to Cyfarthfa. He was very friendly with William Menelaus. Menelaus was a hot-tempered man, and Pearce was quite the opposite. “Now Menelaus”, he said, “you are very foolish to go on so; it would pay you better to pay a man 30s a week to do the swearing”. He was a good horologist, a microscopist and a musician. Amongst his other makings was a machine to delineate sound curves.

My last visit to Cefn Cemetery was to pay the only tribute to his memory, and I was rather surprised at the paucity of attendance, knowing how highly he was esteemed. He sleeps, however, quite as soundly. During one of the many conversations I asked him, “Why did you leave Cyfarthfa?”. “Well, you see, I had been there some time, and got on very well with the old ones, but somehow or other, not much with the young ones, and rather than lose my temper I resigned”.

To be continued at a later date.

Today marks the 200th anniversary of the death of one Merthyr’s greatest pioneers – Watkin George.

Watkin George is not a name that most people think of when talking about Merthyr’s great men of the past, but his contribution to the town’s history and his legacy is incalculable.

Born in about 1759 in Trevethin, Pontypool, very little is known about his early life, other than he trained as a carpenter, but by his early thirties, he had had married Anne Jenkins (of also of Trevethin), and had moved to Merthyr to work at the Cyfarthfa Ironworks as an engineer, as his expertise in designing and building metal structures had become well known.

He soon became the foundry manager at the Cyfarthfa Works, and in 1792, Richard Crawshay appointed him as a partner in the business. One of his first projects as partner was designing the Pont-y-Cafnau (Bridge of Troughs), a combined tramroad and enclosed aqueduct built to supply the works with limestone and water.

This was closely followed by the incredible and innovative design for a mechanism to pump air into the blast furnaces – a huge timber aqueduct spanning the River Taff and providing water to power a 15m diameter waterwheel, used to work an air pump for blowing the iron smelting furnaces. The Gwynne Aqueduct and ‘Aeolus Waterwheel’ soon became famous throughout the country, and visitors would come to Merthyr just to see them. Indeed Some contemporary accounts actually referred to the Aeolus Wheel as ‘the Eighth Wonder of the World’.

In 1799, George designed what would become his most iconic structure – the Old Iron Bridge, and two years later he designed the Ynysfach Ironworks.

In about 1805, having helped Cyfarthfa Ironworks expand, George left the partnership. Reports vary on the amount of money he amassed for his 13 years of service, either £40,000 or £100,000 — “equal to one share”. He joined Pontypool Ironworks as partner to its owners Capel Hanbury Leigh (1776-1861) and Robert Smith, restructuring the works and making great improvements to balling and refinery operations.

In 1811 he prepared a design for Chepstow Bridge – a series of cast iron spans on the existing piers. His design was not adopted, and the new bridge was eventually designed by John Urpeth Rastrick. George’s designs for the Chepstow bridge are his last known work.

Watkin George died on 10 August 1822 and was buried at St Cadoc’s Church in Trevethin.

Today, of his works, the Ynysfach Ironworks Engine House still stands, and his Pont-y-Cafnau is the oldest surviving example of a cast iron railway (tramway) bridge and aqueduct, and is probably the second oldest surviving iron bridge in the British Isles (after Ironbridge in Shropshire), so he is certainly someone who should be remembered amongst the great men of Merthyr.

Merthyr’s Bridges: The Iron Bridge

In our series looking at the bridges of Merthyr, we come to Merthyr’s most iconic bridge, and indeed one of Merthyr’s most iconic lost structures – the Old Iron Bridge.

The Old Iron Bridge, or the Merthyr Bridge as it was originally called was commissioned by William Crawshay to replace a stone bridge that had been washed away by a flood. This act was not entirely altruistic on the part of Crawshay, as the only other bridge across the River Taff in town was Jackson’s Bridge, which had been built in 1793 by the Dowlais Iron Company.

Watkin George, the principal engineer at the Cyfarthfa Works was tasked with designing the new bridge, and he conceived a structure fabricated with cast iron sections. To span the River Taff, George had to design a bridge that would span between 65 to 70 feet from bank to bank, so single cast iron beams would be impractical, as they were limited to 20-25 feet in length due to the possibility of the iron failing due to the continuous traffic that would use the bridge.

He decided, therefore to build a structure comprising three separate sections between 22 and 24 feet long, the thickness of the iron being one and a quarter inches, and he constructed the bridge as a cantilever, with the two end sections mounted on buttresses built on the banks of the river with a convex central section fixed between them.

Work started on the bridge in the middle of 1799, and was completed by April the following year. The new bridge had an overall length of 64 feet, and was five feet wide.

The bridge was in constant use as the only bridge in the centre of Merthyr until a new bridge – the Ynysgau Bridge, also called the New Iron Bridge, was built next to it in 1880.

The amount of traffic using the bridge can be illustrated in the table below (originally from Merthyr Historian Vol 2, used with the kind permission of The Merthyr Historical Society). Following construction of the new bridge, The Old Iron Bridge was used primarily as a footbridge.

In 1963, the bridge was dismantled as part of the refurbishment and ‘improvement’ of Merthyr. The remains of the bridge – indeed the vast majority of it, now lie gathering dust in a warehouse in Merthyr, and all attempts by local historical groups to have the bridge re-erected somewhere in the town (it can’t be re-erected in its former position as the river has been widened), have failed.

The Aeolus Waterwheel – Merthyr’s Great Wonder

When Rev Sir Thomas Cullum (8th Baronet Cullum) visited Merthyr Tydfil in 1811, one of the sights he was most taken with was the mighty Aeolus Waterwheel at the Cyfarthfa Ironworks, and he even called it ‘the wonder of the place’. Some contemporary accounts actually refer to it as ‘the Eighth Wonder of the World‘. I wonder how many people in Merthyr have actually heard of it nowadays?

When Richard Crawshay became sole owner of the Cyfarthfa Works in 1791, he began making plans to extend the works and come up with innovative ways to increase iron production. In 1792, he made the engineer Watkin George a partner in the firm, and the latter began making significant progress in maximising the potential of the works.

His major contribution was the construction between 1793 and 1797 of a huge overshot waterwheel to provide the air for the four blast furnaces.

According to volume 5 of Rees’s Manufacturing Industry (1819-20):

“…..the water-wheel is 50 feet in diameter and six feet wide: it is chiefly made of cast iron, and has 156 buckets. The axle is a hollow tube, and is strengthened by twenty-four pieces of timber applied around it. On each end of the axis is a cog-wheel of twenty-three feet diameter, which turns a pinion. On the axis of these are two cranks, and fly-wheel twenty-two feet diameter, and twelve tons weight; each of the cranks gives motion to a lever, like that of a large steam-engine, and works the piston of a blowing cylinder or air-pump 52½ inches in diameter, and five feet stroke, which blows air into the furnace, both when the piston goes up and down. The work on the other side being the same, it actuates in the whole four of these double cylinders; the wheel makes about two and a half turns per minute, and each cylinder makes ten strokes.”

At the time, it was the largest waterwheel of its kind in the world and was named Aeolus after a character in Greek Mythology. Aeolus, as mentioned in the Odyssey and the Aeneid, was the keeper of the winds and king of the island of Aeolia, one of the abrupt rocky Lipara islands close to Sicily. Later classical writers regarded him as a god.

The wheel was operated by water fed from streams across the river and transported by a massive iron and wood double aqueduct mounted on stone piers between 60 and 70 feet high. This was the famous Gwynne Aqueduct. Sir Charles Manby (later Secretary of the Institution of Civil Engineers) visited Merthyr and commented that the aqueduct:

“…..maintained an apparent lightness of the whole that contrasted with the massy [sic] boundary of the river, has not only a singular, but also a very interesting and pleasing appearance.”

This is the same aqueduct that was mentioned in the previous post about the Pont-y-cafnau (http://www.merthyr-history.com/?p=678)

The Aeolus Waterwheel continued to power the blast furnaces until the 1820’s when it was replaced by a steam powered engine, and was subsequently demolished.

Merthyr’s Bridges: Pont-y-Cafnau

The Grade II* listed Pont-y-Cafnau over the River Taff in Cyfarthfa is thought to be the world’s oldest iron tramroad bridge. An influential early prototype and is a unique survivor of its kind, it is also an aqueduct, with a water trough below the deck. Its designer was Watkin George (c.1759-1822), the chief engineer of the nearby Cyfarthfa Ironworks, which it served, and the bridge/aqueduct enabled the movement of limestone on its tram rails and a water supply, both for the ironworks. The limestone came from the Gurnos Quarries, and the water from a leat supplied by the Taf Fechan. The water was used to drive waterwheels to generate power to run machinery for iron smelting.

The structure was designed sometime in 1792 and construction began in January 1793 and the bridge was completed some time before 1796.

The distinctive appearance of the bridge is created by two large cast iron A-frames, which span the river, their raking ends embedded in the coursed rubble abutment walls on either side. The span measures 14.3m. Three transverse iron beams, at the halfway and quarter-points, connect the A-frames and support the deck. George was originally a carpenter and he used carpentry techniques for the ironwork – mortise-and-tenon and dovetail joints can be seen.

The deck consists of rectangular aqueduct trough, 1.9m wide and 610mm high, made of long iron plates. The trough is covered by an iron deck, cast in sections, on which was laid the 1.22m (4ft) gauge tramroad. Wagons ran on straight iron rails carried on iron chairs. Some chairs and sleepers are still in place along the full length and segments of rail survive at the southern end.

The cast iron handrails were supported at the centre and quarter points of the span. Most of the original cast iron railings have now been replaced.

In 1795, a second bridge was cast from the same patterns to carry an extension of the tramroad and aqueduct from the ironworks to the Glamorganshire Canal. This bridge, sadly, no longer exists.

Shortly after Pont-y-Cafnau was completed, the Gwynne Water Aqueduct (completed 1796) was constructed over the top of it. Gwynne Water was 185m long, built entirely of timber and used the cast iron uprights of the bridge for support. it supplied water to the 15m diameter Aeolus waterwheel, also designed by George, which powered an air pump for the blast furnaces. Presumably, the extra bracing that has been added to the bridge dates from this work. Nothing of the second aqueduct remains.

Pont-y-Cafnau is a Scheduled Ancient Monument as well as a Grade II* listed structure. The iron trough no longer carries water. However, its name means “bridge of troughs”, testifying to its former life.

The bridge influenced the construction of other, better known, aqueducts. In 1794, Shropshire ironmaster William Reynolds (1758-1803) made a sketch of it. Reynolds’ involvement in the rebuilding of Thomas Telford’s (1757-1834) navigable Longdon on Tern Aqueduct on the Shrewsbury Canal in 1796 seems to have led Telford to reconsider using stone and to opt instead for cast iron. It was also the prototype for Telford’s famous Pontcysyllte Aqueduct, which opened in 1805.
