Map of North America from the Best Authorities Engraved by John Russell and published by Rivington, Wilkie and others, London 1818 for an Atlas to Guthrie’s Geographical Grammar. On paper size 25 by 21 cm. Uncoloured. Apart from Louisiana most of the area west of the Mississippi and Missouri remains uncharted apart from the occasional river, though many features all along the Pacific coast from Alaska down to Panama are identified. The United States and Canada have some areas that bear the unusual names of the period (East Florida in the US, New South Wales in Canada). Guthrie’s Atlas was first published in the late 18th century and the London engraver and printer John Russell provided the maps of the 1818 edition. The map has a piano key style border with latitude and longitude along each edge. Has been folded. Good to VG condition.
