The outfit of the Bar-20 was, perhaps, the most famous of all from Canada to the Rio Grande. The foreman, Buck Peters, controlled a crowd of men (who had all the instincts of boys) that had shown no quarter to rustlers, and who, while always carefree and easygoing (even fighting with great good humor and carelessness), had established the reputation of being the most reckless gang of daredevil gunfighters that ever pounded leather.” (from Bar-20 ) Included in this big omnibus are three long novels, Bar-20 , Hopalong Cassidy , and The Coming of Cassidy . These are Clarence Mulford’s first three Cassidy novels, stories that helped to establish the genre conventions of the Western in the first decade of the twentieth century, and which introduced the famous character, Hopalong Cassidy. Cassidy, was of course, the hero of many films, and a classic, long-running network television show, starring silver-haired William Boyd and his horse, Topper.
