This map of New Hampshire was completed in 1794 by Samuel Lewis (1753 or 1754–1822), a Philadelphia draftsman and engraver, for inclusion in General Atlas for Carey’s Edition of Guthrie’s Geography Improved, published in Philadelphia in 1795. It shows the five counties of New Hampshire‒Cheshire, Grafton, Hillsborough, Rockingham, and Stratford‒with their boundaries, principal towns and settlements, roads and waterways, mountains, and islands. Much of the map’s northern region is blank, with a note across the top, “Indian carrying place” (canoe portage). Lewis identifies the present-day White Mountains as the White Hills, which he describes as appearing “many leagues off at Sea like White Clouds just rising above the Horizon." Dartmouth College, founded in 1769, is indicated on the left side of the map. James Smither of Philadelphia engraved the map. Mathew Carey (1760–1839) was an immigrant from Ireland who worked as a publisher in Philadelphia, specializing in maps, atlases, and works of geography. In 1795 he issued the first atlas published in the United States, the American Atlas. Early American publishers such as Carey were not restricted by international copyright agreements and reused European sources to print extensive atlases and geography texts. Carey combined William Guthrie’s European maps, originally published in London in 1770, with updated maps of the United States to produce Guthrie’s Geography Improved. The map is from the Rochambeau Collection at the Library of Congress, which consists of 40 manuscript maps, 26 printed maps, and a manuscript atlas that belonged to Jean-Baptiste-Donatien de Vimeur, comte de Rochambeau (1725‒1807), commander in chief of the French expeditionary army (1780‒82) during the American Revolution. Some of the maps were used by Rochambeau during the war. Dating from 1717 to 1795, the maps cover much of eastern North America, from Newfoundland and Labrador in the north to Haiti in the south. The collection includes maps of cities, maps showing Revolutionary War battles and military campaigns, and early state maps from the 1790s.
