Rural route maps. Maps of those counties in which the rural delivery pos- 

 tal system is completely established are being issued by the Post Office 

 Department. The maps are published in two forms, one giving simply 

 the rural free delivery routes starting from a single given post office, 

 sold at 5 cents; the other, the rural free delivery routes in an entire 

 county, sold at 20 cents. In both forms, not only the rural route is given, 

 but also roads, rivers, creeks, schools, churches, and even the residences 

 of people living along the lines of the routes, in fact, everything in the 

 nature of a land-mark. They are on the uniform scale of an inch to a 

 mile. Sun-print copies are produced in response to special calls, ad- 

 dressed to the Disbursing Clerk, Post Office Depaitment. These maps 

 should not be confused with the post route maps.
