A Geological Map of England, Wales, and Part of Scotland, Showing also the Inland Navigation with the Railroads & Principal Roads

London: J. & C. Walker, March 15th, 1838.. Map dimensions 93 x 65 cm, overall dimensions 101 x 66 cm. Large folding geological map with two cross-sections to the lower edge the strata of southern England from Land's End to the German Ocean and those along the spine of the country from Cumberland down to Newhaven, all vividly coloured according to the strata, dissected into 30 sections and mounted on linen, textured green paper to the folded end sections, folds into the original dark green cloth slipcase with a gold lettered label to the upper panel. Slight wear to the case, some light soiling to the map, very good overall. A less common and slightly smaller variant of James Alexander Knipe's map, first published in 1835 and thence frequently updated and reissued using fresh evidence gathered from geological fieldwork. As with the original map, Knipe's name has here been completely excised and only those of the publishers remain. Here the title has also been shortened, removing references to rivers and canals - a clear indication of how rail and road had very quickly become the principal means of inland navigation. This map also benefits from the second north to south cross section, not included on the larger version, which includes the London Basin towards the right edge.
