Devon (/ˈdɛvən/), also known as Devonshire, which was formerly its common and official name, is a county of England, reaching from the Bristol Channel in the north to the English Channel in the south. It is part of South West England, bounded by Cornwall to the west, Somerset to the northeast, and Dorset to the east. The City of Exeter is the county town; seven other districts of East, Mid, North and West Devon, South Hams, Teignbridge, and Torridge, are under the jurisdiction of Devon County Council; Plymouth and Torbay are each a part of Devon but administered as unitary authorities. Combined as a ceremonial county, Devon’s area is 6,707 km2 (2,590 square miles.)
John Cary (c. 1754 – 1835) was an English cartographer. Cary served his apprenticeship as an engraver in London, before setting up his own business in the Strand in 1783. He soon gained a reputation for his maps and globes, his atlas, The New and Correct English Atlas published in 1787, becoming a standard reference work in England. In 1794 Cary was commissioned by the Postmaster General to survey England’s roads. This resulted in Cary’s New Itinerary (1798), a map of all the major roads in England and Wales. He also produced Ordnance Survey maps prior to 1805. In his later life he collaborated on geological maps with the geologist William Smith. His business was eventually taken over by G. F. Cruchley (1822–1875).
