As Americans moved west into new lands opened to settlement following the Louisiana Purchase, establishing communication channels with the rest of the country became increasingly important. Postal service was crucial to linking new settlers on the frontier to their family, friends and business interests back east, as well as emerging markets along the Mississippi and Missouri rivers. In his book, "Postal Service in Territorial Missouri, 1804–1821," author Robert G. Schultz examines the growth and development of such service operating across the intervening miles of wilderness in the area that was to become the state of Missouri. In addition to the innumerable service problems these services faced, he offers an in depth look at their postal routes, post offices and postmasters. Join us as Schultz, for the first time, shares his research on this fascinating and little-examined subject.
