Transcriber’s Notes Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in the original book; otherwise they were 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. Footnotes, originally at the bottoms of pages, have been collected, sequentially renumbered, and repositioned between the end of the last chapter and the Index. The index was not checked for proper alphabetization or correct page references.
