Obvious spelling/typographical and punctuation errors have been corrected after careful comparison with other occurrences within the text and consultation of external sources.

Inconsistent hyphenations have been retained: school-room/schoolroom, school-house/schoolhouse, note-book/notebook.
On page 19 an apparent printing error interchanging the section heading “5” and the first line of the following text has been corrected.
Re the question at the end of Chapter III: the cover of the 1913 edition shows a statue of a man, possibly William Penn, surrounded by silhouettes of the six continents. The cover of the 1914 general edition shows the dome of the Capitol at Washington (cf the frontispiece) in place of the statue.
The original book was published at Philadelphia by the Christopher Sower Company, 124 North Eighteenth Street. The copyright date was 1913 and 1914.
