Rim o’ the World [EPUB ebook] 
With linked Table of Contents

Black Rim country is called bad. The men from Black Rim are eyed askance when they burr their spur rowels down the plank sidewalks of whatever little town they may choose to visit. A town dweller will not quarrel with one of them. He will treat him politely, straightway seek some acquaintance whom he wishes to impress, and jerk a thumb toward the departing Black Rim man, and say importantly: “See that feller I was talking with just now? That’s one of them boys from the Black Rim. Man, he’d kill yuh quick as look at yuh! He’s bad. Yep. You want to walk ’way round them birds from the Rim country. They’re a hard-boiled bunch up that way.” And he would be as nearly correct in his estimate as such men usually are.
