Hi Penny,
I think I may not be able to locate it for it is in hardcopy format and much of our goods are still packed following a recent move. I will look when I get to the box for it is an interesting read.
I do recall, one of the outcomes of the War that never was rectified during or after Reconstruction involved Railroad tarrifs on north to south and south to north shipments.
This problem may still exist today if I recall correctly.
