Practical Blacksmithing would be 1889, 1890, 1891.
I have a book from around WW1 on smithing.
With the information in the Civil War you are getting some nice spaced dates. However a lot of info tends to get copied over and re-used from time to time without re-examination, often causing difficulties. (even Theophilus was guilty of this in 1120 A.D. with the "how to carve rock crystal" section.)
