1835 Hall Map of North America

A beautiful example of Sidney Hall's 1835 map of North America. Hall's map covers North America from the Isthmus of Panama to the Arctic Circle, embracing all of Central America, Mexico, the United States, modern day Canada, and Alaska. Hall, as C. Wheat notes in Mapping the Transmississippi West, closely followed

Lewis and Clark (with the 'Stinking water'), and … having Long's Lewis River rising just under 'Binghorn or Long's Peak,' with 'James Peak or Sierra Almagro' to the south, and further west the mythical rivers in all their glory.

Wheat here refers to the several speculative rivers that empty into the Pacific in what is not California, including the Mongos, Sacramento, Joaquin, Buenaventura, and San Felipe. Both the Great Salt Lake, identified as Timpanagos, and Utah Lake, identified as Lake Teguayo, are rendered following Humboldt.

Curiously Hall's concedes all of British Columbia to the United States as far north as 54 40,' a highly unusual move for a British cartographer. In the first half of the 19th century the Pacific Northwest was the last frontier in the century's long slaughter of the American beaver in the name of European fashion. Both the British, in the name of the Hudson Bay Company, and the Americans, championed by John Jacob Astor's Pacific Fur Company, were eager to claim monopolistic right over the region. Astor's establishment of Fort Astoria on the Columbia River, marked here but identified following the British nomenclature as Fort George, only served to further tensions with the Northwest Company - the Pacific subsidiary of the Hudson Bay Company. The dispute escalated, giving rise to the Oregon Boundary Dispute and the American expansionist slogan 'Fifty-four Forty or Fight!' The dispute was not resolved until the 1846 Oregon Treaty which, through concessions on both sides, formally set the boundary at the 49th parallel. The name 'Oregon,' we note, appears nowhere on this map, instead it is identified as the 'Western Territory.'

This map is particularly interesting as it is one of the earliest maps to accurately depict the Northwest Passage, predating the Robert McClure expedition by more than 15 years. Hall correctly maps what are today called the Northwestern Passages between Baffin Bay and the Arctic Ocean. His mapping extends as far west as Melville Island and Banks Island, though does not include Prince Patrick Island. Even so, beyond Melville and Banks Islands, there is little but ice and seasonally open sea as far as Alaska and the Bearing Straits.

Sidney Hall's New General Atlas was published from 1830 to 1857, the first edition being the most common, with all subsequent editions appearing only rarely. Most of the maps included in the first edition of this atlas were drawn between 1827 and 1828 and are most likely steel plate engravings, making it among the first cartographic work to employ this technique. Each of the maps in this large and impressive atlas feature elegant engraving and an elaborate keyboard style border. Though this is hardly the first map to employ this type of border, it is possibly the earliest to use it on such a large scale. Both the choice to use steel plate engraving and the addition of the attractive keyboard boarder are evolutions of anti-forgery efforts. Copper plates, which were commonly used for printing bank notes in the early 19th century, proved largely unsuitable due to their overall fragility and the ease with which they could be duplicated. In 1819 the Bank of England introduced a £20,000 prize for anyone who could devise a means to print unforgeable notes. The American inventors Jacob Perkins and Asa Spencer responded to the call. Perkins discovered a process for economically softening and engraving steel plates while Spencer invented an engraving lathe capable of producing complex patters repetitively - such as this keyboard border. Though Perkins and Spenser did not win the prize, their steel plate engraving technique was quickly adopted by map publishers in England, who immediately recognized its value. Among early steel plate cartographic productions, this atlas, published in 1830 by Longman Rees, Orme, Brown & Green stands out as perhaps the finest. This map was issued by Sidney Hall and published by Longman Rees, Orme, Brown & Green of Paternoster Row, London, in the 1835 edition of the Sidney Hall New General Atlas.
