-  Mapa, que comprende la Frontera, de los Dominios del Rey, en la America Septentrional. This detailed map of the Internal Provinces of New Spain (northern Mexico and southwestern United States) reflects the Spanish government’s concern during the second half of the eighteenth century about frontier defenses, especially in response to American Indian attacks and the potential movement of European enemies into the region. The 1766-1768 survey involved a two-year, 6,000 mile trek extending from the Gulf of California to the Red River in Louisiana. Since this map was never published, British Americans were not aware of the extent of geographical and ethnological information known about the Spanish frontier.
