"Thanks, but I can't see anything about imports, broken down by region."
That is exactly right. Tariff collection data and general Treasury reports tell you virtually nothing. It has to be studied in detail.
"Pea Ridge would have us believe that while the South exported directly from New Orleans, Savannah, and other southern ports, it imported everything via ports in the North, then sent it all South by coastal steamer."
I said neither of those things. Actually it goes to show your willingness to support your fantasies
Then why did you tell us that the 1860 report was where we could find the information that you used?
