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 are two trivialities that must be stated about Penydarren before alluding to that which will perpetuate its memory for all time. (1) The end of the forge was a pure example of Doric architecture, (2) and the small stack of the roll lathe boiler was an exact model one-fifth the size of the monument on Fish Street Hill, London.
The Petherick family had positions in the early days of Penydarren, and Evan Hopkins, the author of “Magnetic Distribution of Metalliferous Veins” went thence to South America about the deposits there. It is, however, as the parent of the locomotive that Penydarren will ever be remembered. As there seem to be doubts about some things I will endeavour to put it clear, although not strictly within my own personal recollections.
Notwithstanding the great genius of James Watt, and the wonderful sagacity of Mathew Boulton, the idea of using steam in a cylinder to give motion to a piston, and allowing it then to escape into the atmosphere, was thought to be too dangerous, and the condensation of the steam was adhered to them.
Richard Trevithick (left), however, more daring, did not allow himself to be influenced by such fears, but towards the close of the 18th century began to put his thoughts into use. He made a road locomotive, and in 1802, injunction with Andrew Vivian, obtained the patent.
It is only my idea that the Pethericks were the means of introducing Trevithick to Penydarren, for one (a Mr John Petherick), wrote in 1858 that, “I perfectly remember when a boy, about the year 1802, seeing Trevithick’s first locomotive, worked by himself, come through the principal street of Cambourne”. But be that as it may, this, or another of Trevithick’s make, travelled to London, and often ran upon some ground near Bethlehem Hospital, and also where Euston Station now stands. It must be borne in mind that it was thought quite impossible to get sufficient grip between the wheels and a road to cause them to move the carriage forward.
It is clear Trevithick was in the neighbourhood about 1800, for stationary engines were made by him or from his designs both at Penydarren and Tredegar Works. These have been seen at work by me. His first locomotive was used about the works, and very probably hauled some of the cinders which for the tip alongside of the Morlais Brook and River Taff. The fact of an engine having cast iron wheels, running on an iron road being able not only to propel itself forward but draw a load after it was there demonstrated, and must have been a subject of controversy because a bet of £1,000 was made between Mr Homfray and Mr Crawshay as to the possibility of its taking ten tons of iron down to the basin and bringing the empty trams back.
The ten tons of iron was take to its destination, but for some cause the engine and the empties did not return to the works as satisfactorily as hoped for. The weight of the engine is stated to have been about five tons, and the gross weight altogether of 25 tons.
It seems as if Mr Homfray was an exceedingly hot tempered man, and it is clear that Trevithick had the same infirmity. This I have from one who was able to recall both personally. It would scarcely be proper to trace here how engines were designed by Trevithick, and did work elsewhere soon afterward, and how Trevithick himself having more enticing engagements allowed others to carry on the work he had begun.
To be continued at a later date…..
Meta Scott was born Sarah Margaret Scott in 1860, the daughter of William Scott, a grocer at Brecon Road.
