“the Mississippi, the Missouri, and the Ohio Rivers will be subject to Southern tolls.” As would good moving north on these water routes.
Charleston would have been in a foreign port, anything coming from Charleston would have been subject to the U.S. tariff. if moved out of Charleston by ship to a Northern Port.
Iron rail off loaded at Savannah and shipped North would have to be off loaded and reloaded several times before it got out of the South, since there was no standard gauge to the rail system. Why would rail be imported to New York, the North could produce all the iron rail to support its railway system. Now the South on the other hand had one mill in the entire Confederacy that could produce iron rail.
Read the newspaper editorial and keep in mind that tariffs are charged on imports, not transports.
Then, explain this:
“The difference is so great between the tariff of the Union and that of the Confederated States, that the entire Northwest must find it to their advantage to purchase their imported goods at New Orleans rather than at New York. In addition to this, the manufacturing interest of the country will suffer from the increased importations resulting from low duties.“
