The two short stories included in this volume are reprints:--the
"Story of a Piebald Horse" from a book of travel and adventure in
South America, long out of print; the other, "Niño Diablo," is taken,
by permission, from _Macmillan's Magazine_. The two long stories now
appear for the first time, excepting only the incidents of the English
invasion told in "El Ombú," and the Appendix to the same story, which
formed part of an article describing the game of El Pato in the
_Badminton Magazine_.
