| Description | Geological colouring and extensive notes by George Bellas Greenough, [1813-1839], on topographical base map 'A New Map of South Wales', by Nathaniel Coltman, published by Laurie & Whittle, 4th edition, 1813. Greenough no.367. Scale-1:300,000. Dissected on cloth in case. |
| Administrative History | The geological colouring and notes are not dated, but there are at least two notes which cite publications from 1814 & 1832 [John Kidd, "Notes on the Mineralogy of the neighbourhood of St. David’s, Pembrokeshire", Transactions of the Geological Society of London, Series 1, Volume 2 (1814), pp79-93 & W D Conybeare, "On the structure and extent of the South Welsh Coal-basin", Philosophical Magazine, 2nd series, vol XI (1832), pp110-114]. Part of the colouring is clearly based on the work of Murchison from the late 1830s.
On the top left are a short list of various mine owners who had 'maps of strata of their neighbourhood', comprising:
Sir John Morris, Claysmont near Swansea
Mr Smith, near Neath
Mr Lockwood, secretary to the Irish Chancellor nr Swansea - the steward of his mine is Mr Bevan
George Ward[e] (d.1830), Woodland Castle nr Swansea
Joseph [Tregelles] Rice of Neath Abbey Iron Works
The map is cited in the article: F J North, "From the Geological Map to the Geological Survey", 'Transactions of the Cardiff Naturalists Society' vol. 65 (1932), as being used in drafting the first edition of George Bellas Greenough's 'Map of England and Wales' (1820). This may be the case, however, as some of the notes appear older than others perhaps being reworked for the second edition of the map (published 1840). |
