Transcriber's Notes:

Typographical errors in spelling and punctuation repaired; variant spellings changed when there was a clear majority.

The following variant spellings were retained: "depot" (used for New Orleans) and "depôt" (used for rail-road); "moschetoes" and "mosquitoes"; "enquir" and "inquir" roots (used equally); "Pittsburg" (Miss.) and "Pittsburgh" (Pa.); "Cleaveland" (Ohio) (per Columbia Gazetteer of the World, this was the original name, after its founder Moses Cleaveland); "Zimple" and "Zimpel"; "regime" and "régime."

Hyphenation variants changed to majority use (with priority on usage in headings and text, over usage in index or tables); retained when equal (wood-lands and woodlands, re-transferred and retransferred, pre-eminence and preeminently). "steam-boat" and "steam boat" changed to "steamboat" except on p. 27, where "Steam Boat" is used for the first appearance of a new technology.

Punctuation after chapter and section headings, and illustration captions (periods, commas, no punctuation) was inconsistent; standardized to no punctuation. Brackets around "see Route" references changed to more frequent parentheses.

P. 20, "Vandreuil" corrected to "Vaudreuil."

P. 73, Meteorological table has been split for better displaying (text only).

P. 84, "inexaustible" changed to "inexhaustible."

P. 103, "Diocess" retained; per Oxford English Dictionary (OED) correct for time period.

P. 147, "Tchapitoulas" corrected to "Tchoupitoulas."

P. 174, "cotemporaries" retained; per OED, this was a common period variant for contemporaries.

P. 205, Route 4; "Tombigkbe" changed to "Tombigbee."

P. 206, Savannah. Original shows cumulative miles 2196. Transposition repaired.

P. 206, Route 10 heading, "Ala." to more frequent "Al."

P. 213, index; originally left justified "Seven blocks" now indented under "Fire consumes."

P. 222, index; originally left justified "Branch Bank" now indented under "United States."

The following discrepancies in route tables were retained as shown in the original:
P. 202, Smithfield, "1" in original would add up to 1086 cumulative (11 mile discrepancy).
P. 203, Greenupsburg, "13" in original would add up to 1675 cumulative (1 mile discrepancy). Georgetown "7" and Beaver "13" appear to be averaged, since each addition does not add up, but their cumulative addition (20 miles from Welleville to Beaver) does add up.
