Artist/engraver/cartographer: Engraved by J & C Walker. Provenance: "Maps of the Society for the Diffusion of Useful Knowledge", published by Charles Knight, 90 Fleet Street, London, under the superintendance of the Society for the Diffusion of Useful Knowledge. Type: Antique steel engraved map with original outline hand colouring. The map was published within the 1848 edition of the SDUK atlas, having been originally engraved in 1844 ( this date is printed on the map). The international borders printed on the map reflect the situation in 1844. However the hand colouring, presumably applied upon publication in 1848, reflects the international borders at that later date. The borders on the map have been drawn to show Texas as being part of Mexico, reflecting the situation prior to the Texas revolution which ended in the Texan declaration of Independence from Mexico 1836, although given that the map was engraved in 1844 the cartographer appears to have reflected the position of Mexico which had refused to recognise the independence of the Texas Republic.

However the hand colouring reflects US-Mexican border after the Mexican-American war which finished in 1848, as a result of which Mexico ceded New Mexico & Alta California while in 1848 the United States was also occupying Baja California. From the point where the Columbia River meets the 49th parallel, the border between the United States and British North America (now Canada) is printed on the map as following the course of the Course of the Columbia River to the south and west until it reaches the Paci
