This transcription follows the text of the edition published by
Grosset & Dunlap in 1927 (by arrangement with Harper & Brothers).
However, the following alterations have been made to correct what are
believed to be unambiguous errors in the text:
* “be would consult” to “he would consult” (Ch. VI);
* “the man” to “The man” (Ch. IX);
* “arroused” to “aroused” (Ch. X);
* “oxyacetlene” to “oxyacetylene” (Ch. XVI).
