Historians and publicists have spoken, and continue to speak, of "Southern opinion" and of the "Southern attitude" as if these could be definitely weighed and measured.

No one who really knows the whole South could be guilty of such a mistake.

The first difficulty is to determine the limits of the South.

The census classification of States is open to objection.
Delaware, Maryland, and West Virginia are included in the South, and so is Kentucky.

Missouri is excluded, but a place is made for the new State of Oklahoma.
