The line of trees to the left has marked a boundary for 200 years. Established in 1765, it defined the eastern limits of the Old Natchez District, running from a point 12 miles east of Vicksburg southward to the 31st parallel. First surveyed in 1778, it was reaffirmed by Spain in 1793 and by the United States in 1801. Since 1820, it has served as the boundary between Hinds and Claiborne Counties, Mississippi. Established in 1802 at the lower Choctaw Line, Red Bluff Stand was for several years the last place a northbound traveler could obtain provisions, and John Gregg advertised groceries, ground coffee ready to put up, sugar, biscuit, cheese, dried beef or bacon, other articles needed by travelers going through the nation, and horseshoeing on short notice.
