Punctuation and spelling were made consistent when a predominant preference was found in the original book; otherwise they were not changed. Inconsistent hyphenation was not changed.

Simple typographical errors were corrected; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced.

Illustrations in this eBook have been positioned between paragraphs and outside quotations. In versions of this eBook that support hyperlinks, the page references in the List of Illustrations lead to the corresponding illustrations.

Numbers corresponding to those in the List of Illustration have been added to the captions as an aid when reading versions of this eBook that do not support hyperlinks.

Footnotes, originally at the bottoms of pages, have been renumbered, collected, and placed just before the Index.

The index was not systematically checked for proper alphabetization or correct page references. The entry and sub-entries for “Alaska” were out-of-sequence, and were moved by Transcriber.
