This collection of short stories or novellas contains some of the best short work by Zane Grey. Some of them have since then been reprinted in other collections, and stand alone volumes under other titles. But at the time of this printing none of these stories had appeared in book form except as a first edition by Walter J. Black--a rare book to be found. The lead story, The Camp Robber had appeared in McCall's Magazine in 1928; Amber's Mirage in Ladies' Home Journal in 1929; Fantoms of Peace in Munsey's in 1913; but the other three--On Location; John Silver's Revenge, and Loose Bridles had never been published previously. All in all, this collection represents both Zane Grey's earliest work, and some of his later material written in the 1930's when his fame had waned, and the Depression had dried up many of the markets where he used to sell his work. That in no way lessens the value or content of the work, nor the entertainment one can enjoy from reading a Zane Grey story. I highly recommend this book.
