author
Known for a practical guide to horse training, this little-known writer is associated with a public-domain manual that has stayed in circulation through reprints, ebook editions, and audiobook recordings. The surviving record is sparse, which gives the work an old-book mystery of its own.

by P. R. Kincaid, John J. Stutzman
P. R. Kincaid is credited as a co-author of The Arabian Art of Taming and Training Wild and Vicious Horses, a short public-domain manual often listed alongside John J. Stutzman. The book has remained available through Project Gutenberg, LibriVox, and later reprints, which suggests it has continued to interest readers curious about historical horse-handling methods.
Reliable biographical information about Kincaid is very limited. In the sources I could confirm, there were book listings and author pages, but no clear, well-documented personal history such as dates, places, or a fuller life story.
Because the record is so thin, Kincaid is best introduced through the work itself: a compact nineteenth-century-style handbook focused on taming and training difficult horses, written in a practical, instructional voice.
