An accessible yet well researched and detailed account by Glenn D. Bradley of the operation of the line known as the Pony Express, that lasted for about 16 months before being replaced by the telegraph. A mail route became an imperative in order to connect the eastern U.S. with the growing west coast following the gold rush of California, the lumber camps, and the various needs because of the settling of the western frontier. This work is meticulous yet manages to convey the entrepreneurial and dangerous atmosphere of the time (the hard work being done, repelling of Indian attacks and overall tough working conditions).
