External Link error
The first external link, entitled "An historic and photographic exploration of Penwyllt by John Ball and Venita Roylance", triggers a 'Page not Found' error. This link is to a feature on my old website , but I ceased to maintain this website in April 2011.

The same Penwyllt feature is now on my new website, at the following URL: http://www.jlb2011.co.uk/walespic/archive/030705-3.htm

Kindly update the link as soon as is convenient.

Former 'Background' section
I removed the 'Background' section containing this text (my italics) due to its largely being inaccurate or irrelevant:


 * The geology of South Wales provides it with the basic raw materials structure to be at the centre of the Industrial Revolution. The large natural coal fields enclose significant deposits of iron ore and limestone, each basic to the production of materials via production methods.


 * The best coal in South Wales is found in the eastern sections beneath Rhondda Fawr, where the pressure is highest. The greatest deposits of limestone are found above the western section, around the northern section of Swansea Valley where it borders Brecknockshire. There were also coal deposits below the limestone layer, and the coal which lay underground at Clydach, Ystradgynlais, and Abercraf became more valuable as the Industrial Revolution of the Victorian era led to a huge demand for iron and steel, giving the area prosperity. 

All coalfields are natural, this one - the South Wales Coalfield - does not contain limestone - that is found just beyond its margins. 'Production of materials by production methods' - what does that mean? Rhondda is not in the east of the coalfield and what does 'best' mean in any case? Limestone was worked all along the 'north crop' with the largest quarries further east in the Trefil area. There are no 'coal deposits below the limestone layer', they are all above. The Industrial Revolution preceded the Victorian era.
