Although popularly called the "Mason-Dixie" or "Mason-Dixon" LINE, it is not. The "Mason-Dixon LINE" is a boundary between Penn and Maryland surveyed by Charles Mason and Jeremiah Dixon in the 1700's. But the name (Mason-Dixie line) is popular with poems, stories, songs, jokes, and probably US history in general.
The real so called "Dixie LINE" consists of the actual states that formed the Confederacy during the US Civil War in 1861-1865, and is an imaginary line running from the top of Texas running east along the northern tips of Arkansa, Tennessee, and Virginia; and encompassing all of the states below that imaginary line, for a total of 11 states. The line runs thru the former Indian Territory of Oklahoma.

The confines of a city refer to the boundaries or limits that define its geographic extent. These boundaries can be physical features like rivers, mountains, or man-made boundaries like city limits or municipal boundaries that separate it from neighboring areas.
North America is large enough for the US to fit within its boundaries.
