p 10 Apologies to Col Christopher Miers, it is he rather than Mr. Charles Miers' who should be acknowledged

p 26 DELETE from 'Around 1770' to 'seven years war.'

SUBSTITUTE 'Around 1745 John Miers a London importer of German tinplate appeared on the scene doing business with Pytt and Lewis.

In about 1770 he became the sole owner of Ynyspenllwech in the Swansea valley and other works in the Vale of Neath and the Afan Valley.

His elder son Nathanthiel who had been "disowned" by the Quakers for marrying in Church, ran the family's works in south Wales as an ironmaster at Neath until his early death in 1782. The younger son, John, who had been running the London end of the business took over in south Wales. He died in 1787. In his will he left the Miers works jointly to his nephews John Nathaniel Miers and Samuel Fothergill Lettsom but both were under age and therefore did not fully inherit the works until 1799.
John Nathaniel Miers, grandson of the orginal John Miers married into the great Hill family of the Plymouth Iron works at Merthyr Tydfil. When capital was needed in order to expand the business, John Nathaniel Miers advanced £5000 (A quarter of the new total) and became a partner. Soon aferwards, in 1803, the Plymouth company agreed with the Dowlais and Penydarren Iron companies to build a tramroad for their joint use. In 1804 one of Richard Trevethick's high pressure locomotives was constructed at Penydarren and made several trips along the the tramroad before being converted to stainonary use. It is acknowledged to have been the world's first steam locomotive.
John Nathaniel Miers continued to run the Miers family works in partnership with his cousin Samuel Fothergill Lettsom. He served as High Sheriff of Glamorgan in 1808'.
