TRANSCRIBER'S NOTES
The book cover was modified by the Transcriber and has been put in the public domain.
In the Spanish original version of this work the author quoted the province of Córdoba, in Argentina. However, in the present English translation the province is named Cordova. To avoid confusion with the Spanish city of Córdova, in the present transcription the name has been changed to Córdoba.
A number of words in this book have both hyphenated and non-hyphenated variants. For the words with both variants present the one more used has been kept.
Obvious punctuation and other printing errors have been corrected.
