Just so you understand the real impact of the Morrill Tariff, here for your reading is this:

In its first year of operation, the Morrill Tariff increased the effective rate collected on dutiable imports by approximately 70%. In 1860 American tariff rates were among the lowest in the world and also at historical lows by 19th century standards, the average rate for 1857 through 1860 being around 17% overall (ad valorem), or 21% on dutiable items only.

I've seen that before.
See my post above.

There may be a dispute amongst historians on what, exactly, were the results, but I think at least some of the explanation is in differences among:

1. The original Morrill proposal of 1859 (35th Congress).
   
2. The First Morrill Act of March, 1861 (36th Congress).
   
3. The Second Morrill Act of late 1861 (Civil War).
