This large map of England and Wales is drawn at a scale of about 9 miles to the inch. It is published by the firm of John and Charles Walker. The British Library date an example of theirs to 1835 without stating on what basis. Otherwise I cannot find a record of any copy dating earlier than this one of 1839. The ‘Note’ below the title details the maps sources. These are the British Admiralty for the coasts of England, the topographical detail is largely drawn from the ‘Trigonometrical Survey’, the work of the Board of Ordnance, otherwise known as the Ordnance Survey. They had not yet completed their work so the note states that it ‘comprises upwards of a third part of England & Wales’. The remainder are drawn from the ‘County Maps by Greenwood & Co. and Bryant. Wales is drawn from Walker. ‘Besides these the Compilers have availed themselves of a great mass of local & partial Surveys of Canals, Rail Roads & c. which are too numerous to be particularized’. The whole has been adjusted to allow for the new boundary system brought about by the great Reform Bill of 1832. The new but rapidly expanding railway network is laid down but as yet none are in Scotland. There is a later edition dated 1841, the British Library have one dated 1842, and a later one believed to be the same plates date from 1848 and 1860. Provenance: private collection of Rodney Shirley.
