Those pages show up sideways on the screen, so I printed them to be certain -- they contain no data relevant to this discussion.
I will check out the other links you offer, and let you know my findings.
Let's see if I can help.
Originally you questioned data I posted on the portion of total US exports of Southern origin.
From your postings, it is not clear to me if you want data from sources you trust, or if you want to use primary sources from which you can do your own calculations.
It is also not clear exactly what sources you trust.
As it pertains to trade data, you have only one reliable source.....United States Customs data. It was collected daily, compiled monthly, and supplied to the Census Bureau, United States Treasury, US Congress, and the President.
So back to sideways. If you were unable to see page 48, I will be glad to read it for you.
The chart gives various categories of export/import data for fiscal year ending June 30, 1860.
If you are ok with that year, then a reliable comparison of geographical origins begins with establishing trade total numbers. I trust you would agree with that.
On page 48, column 3, at the bottom, the number there is the total dollar value of US Imports for that year.
That number is fundamental to the question about trade.
Now, staying with page 48, and moving to the right, column 7, at the bottom, lists total Exports for that year.
If you prefer data for 1861, see page 49 which also gives export/import figures for that year. I trust this is acceptable. If not say so now.
You saw my post #1477. .
Any of those will help you compute trade data by individual customs house. As you will see, it can be compiled by port, type, and value, but apparently you did not even look at it.
If you do not want to spend time doing that, see post 1435 for the totals. That data was compiled from Customs.
We already know your findings. You are going to determine that the Union was completely blameless, and that the Southern states were completely at fault.
You have no credibility because you have no objectivity. You are an apologist, and not a searcher for truth.
