Transcriber's note:
Minor typographical errors have been corrected without note. Irregularities and inconsistencies in the text have been retained as printed.
The illustrations have been moved so that they do not break up paragraphs, thus the page number of the illustration might not match the page number in the List of Illustrations.
Mismatched quotes are not fixed if it's not sufficiently clear where the missing quote should be placed.
The cover for the eBook version of this book was created by the transcriber and is placed in the public domain.
Pages 55, 57, 149: The numbers in the tables do not add up correctly as written.
The two photographs that appear between pages 96 and 97 have been moved to page 78 to match the table of contents.
