RIDINGS, SAM P. _The Chisholm Trail_, 1926. Sam P. Ridings, a lawyer, published this book himself from Medford, Oklahoma. He had gone over the land, lived with range men, studied history. A noble book, rich in anecdote and character. The subtitle reads: "A History of the World's Greatest Cattle Trail, together with a Description of the Persons, a Narrative of the Events, and Reminiscences associated with the Same." OP. ROBINSON, FRANK C. _A Ram in a Thicket_, Abelard Press, New York, 1950. Robinson is the author of many Westerns, none of which I have read. This is an autobiography, here noted because it reveals a maturity of mind and an awareness of political economy and social evolution hardly suggested by other writers of Western fiction. ROLLINS, ALICE WELLINGTON. _The Story of a Ranch_, New York, 1885. Philip Ashton Rollins (no relation that I know of to Alice Wellington Rollins) went into Charlie Everitt's bookstore in New York one day and said, "I want every book with the word _cowboy_ printed in it." _The Story of a Ranch_ is listed here to illustrate how titles often have nothing to do with subject. It is without either story or ranch; it is about some dilettanteish people who go out to a Kansas sheep farm, talk Chopin, and wash their fingers in finger bowls. ROLLINS, PHILIP ASHTON. _The Cowboy_, Scribner's, New York, 1924. Revised, 1936. A scientific exposition; full. Rollins wrote two Western novels, not important. A wealthy man with ranch experience, he collected one of the finest libraries of Western books ever assembled by any individual and presented it to Princeton University. ROLLINSON, JOHN K. _Pony Trails in Wyoming_, Caldwell, Idaho, 1941. Not inspired and not indispensable, but honest autobiography. OP. _Wyoming Cattle Trails_, Caxton, Caldwell, Idaho, 1948. A more significant book than the autobiography. Good on trailing cattle from Oregon. ROOSEVELT, THEODORE. _Ranch Life and the Hunting Trail_, New York, 1888. Roosevelt understood the West. He became the peg upon which several range books were hung, Hagedorn's _Roosevelt in the Bad Lands_ and Lang's _Ranching with Roosevelt_ in particular. A good summing up, with bibliography, is _Roosevelt and the Stockman's Association_, by Ray H. Mattison, pamphlet issued by the State Historical Society of North Dakota, Bismarck, 1950. RUSH, OSCAR. _The Open Range_, Salt Lake City, 1930. Reprinted 1936 by Caxton, Caldwell, Idaho. A sensitive range man's response to natural things. The subtitle, _Bunk House Philosophy_, characterizes the book.
