Interesting map of America, published shortly after the dissemination of the Official Account of Captain James Cook's Third Voyage.
The map retains the location of Mendana's Land west of Hawaii, a reference to a pre-Cook Spanish expedition that may have touched on Hawaii in the 16th Century, but for which the details remain debated among scholars.
On the northwest Coast of America, the River of the West, extending from Lake Winnipeg to the Pacific is shown, as is the "Tortolas River," extending from Woods Lake (Lake of the Woods) to the California Coastline, with no sign of the Rocky Mountains given.
In the Arctic Regions, no defined coastline is shown west of Hudson's Bay.
James Whittle (1757-1818) was a British engraver and map printer. Whittle was employed by Robert Sayer (ca. 1725-1794). Together with Robert Laurie (1755?-1836), he took on Sayer’s business when the older man died in 1794. The two traded together as Laurie & Whittle until 1812, when Laurie retired. They had specialized in sea charts and maritime atlases. Whittle then partnered with Laurie’s son, Richard Holmes Laurie, until he died in 1818.
Robert Laurie (1755?-1836) was a British engraver and printseller who specialized in engraving portraits and in publishing maritime charts. His family originated in Dumfriesshire. As a young man he came to London and was apprenticed to Robert Sayer (ca. 1724-1794) in 1770. He received several awards in the 1770s for his mezzotint engraving and printing. He worked for Sayer as apprentice, assistant, and later partner.
In 1794, when Sayer died, Laurie took on his business alongside James Whittle, his fellow Sayer employee. Laurie managed the business and ceased almost all engraving. Instead, he oversaw the prodigious output of printed materials, especially sea charts and maritime atlases. He retired in 1812.
Laurie’s son, Richard Holmes Laurie, took over his part of the business and continued in business as Whittle & Laurie, rather than the previous Laurie & Whittle. Whittle died in 1818, leaving Richard as the sold proprietor of the business. Robert died in 1836 in Hertfordshire.
