B. M. Bower 
Lonesome Trail and Other Stories [EPUB ebook] 

Bower wrote a multitude of short stories featuring the Flying U characters. This one best of the collections. These earlier stories have a more familiar flavor and focus mainly on the original characters, rather than the new ones added later. The title novella, "The Lonesome Trail, " was evidently composed of several previously-published short stories woven together; the earliest of which, "Why Weary Went A-Wooing, " even predated Chip of the Flying U.
