This interesting and historically important map was one of the first to promote to Congress the idea of a transcontinental railroad. The map shows four major routes; Whitney's route (connecting New York, Chicago and Astoria), the Albuquerque-Memphis route (connecting Memphis, Little Rock, Albuquerque and San Diego), the Vicksburg and New Orleans route (from New Orleans to Vicksburg and on to San Antonio and Guaymas) and finally the Mills Telegraph Route (cutting across Texas and Mexico from Matagorda to an unnamed terminal in the vicinity of Los Mochis). Robert Mills proposed linking the two coasts by rail as early as 1819 and was among the project's most ardent supporters. Includes the 7-page disbound report.
