In the third of a three-volume study in the development of the myth of the frontier in US literary, popular, and political culture from the colonial period to the present, Slotkin (English, Wesleyan U.) covers Theodore Roosevelt's and Frederick Jackson Turner's visions of the frontier, and the expression of the frontier myth in such popular culture phenomena as dime novels, Buffalo Bill's Wild West, the formula fiction of 1900-40, and the Hollywood film.
