HURST & COMPANY — Publishers — NEW YORK


Transcriber’s Notes:

Minor spelling, punctuation and typographic errors were corrected silently, except as noted below. Hyphenated words have been retained as they appear in the original text.

On the frontmatter page enumerating the Boy Aviators books, the count listed ("Six Titles") is left as is, even though seven books are listed in the subsequent text.

Note that some archaic spellings have been retained, even though they might be typographical errors; for example, "whity", "propellor", "collapsable", "disillusionized", "stancher", "monocule".

Inconsistent spellings of "airship" versus "air-ship" have been left as is, due to the frequency of both spellings. Inconsistent use of hyphenation in less frequently used words have been corrected to the form used most often.

Inconsistent usage of "anyone" versus "any one" has been left as is, due to the frequency of both spellings.

On the illustration after page 168, the caption has been changed slightly, to match the quote in the preceding paragraph.

On page 263, the error in Morse code (for the letter "O") has been left as is.
