The cover image was created by the transcriber, and is in the public domain.

The illustrations have been moved so that they do not break up paragraphs and so that they are next to the text they illustrate.

Inconsistent hyphenation has been left as printed, except “firebox” has been changed to “fire-box” in the Index to match the spelling in the main body of the book.

Typographical errors have been silently corrected but other variations in spelling and punctuation remain unaltered.

In some tables “Number” has been abbreviated to “No.”, “United States of America” to “U. S. A.” and trailing punctuation has been omitted to make the rows shorter.

The advertisements at the beginning of the book have been re-located to the end of the book, just before the footnote section.
