Original spelling, hyphenation, and grammar has been mostly retained, with a few exceptions.
Hyphenation questions, when the hyphen occurred at the end of a line, were settled in favor of consistency, whenever possible.
Footnotes were moved from the bottoms of pages to the end of the book. Footnotes to the Preface have only one or two digits, e.g. "[11]"; footnotes to the body of the book have three e.g. "[011]".
In tables, "ditto", and "do." were replaced with repetitive text for clarity. Sometimes blank space indicated repetition in a printed table. The first table in [Footnote 187] is an example, wherein the words "Length" and "inches." occurred on the first line only, in the original, but are repeated on each line in this ebook. Whenever it was clear to the transcriber that repetition was indeed meant by white space, text was substituted for the blank. There are rare cases of this which are perhaps debatable. For example, see [ Footnote 83]--tumulus No. 4. In this table, the "Longitudinal base" has measurement 84 feet, and the "top" has measurement 45 feet. The original table had white space under "Longitudinal", suggesting that "Longitudinal top" was meant; and that meaning has been embodied herein.
Footnote [055]: two periods inserted, to end the sentence, and at the end of the footnote.
Page [248]: "permisssion" changed to "permission".
Page [307]: comma inserted after "hoes" in "camp-kettles; knives, hoes squaw-axes,".
Page [308]: period deleted from "having disposed of his hunting apparatus,. she rubs his".
