SMITH, William (1769-1839). A New Geological Map of England and Wales, with the Inland Navigations; exhibiting the districts of coal and other sites of mineral tonnage. London: John Cary, 1820.

Hand-colored engraved folding full-sheet map, divided into 20 rectangular sections and mounted on linen as issued (overall size 767 x 629 mm.), the lower left and upper right linen versos backed in green pastepaper to match the slipcase. Coal-rich areas printed in aquatint with gray wash, the remainder hand-colored with darkened edge-color signifying superposition of strata. Housed in original green pastepaper slipcase with printed label (a bit rubbed, some paper loss at edges).

FIRST EDITION. The map, described on the slipcase label as "reduced from Smith's large map," incorporates all of Smith's many revisions to his original geological wall-map of 1815, including changes made subsequent to the latest issue (post-1817) of the wall-map. "Copies have been recorded dated 1824, 1827, and 1828, but no change in the geological lines has been observed, although the shades of colour may vary" (Eyles). This single-sheet map was published during the same period as Smith's "Geological Survey Atlas of England," a series of 24 slightly smaller county maps colored to show geological strata, issued in parts of 3 maps each from 1819 through 1824. Smith may have planned to sell the general map of England along with the completed series, which, however, remained unfinished. The printed title label on the slipcase states that the present map was "intended as an elementary map for those commencing the study of geology". VERY RARE. Eyles 29; Norman 1961.
