"Map Showing the Routes of Trans-Continental Railways as Explored and as Constructed [with 64 pp report]", U.S. Government

A very detailed map of the western two-thirds of the United States that shows the actual route of the Pacific Railroad "as explored and as constructed" in 1888, and uses red overprinting to display the route according to the survey presented to then Secretary of War, Jefferson Davis in 1855. The map shows very little deviation from the original surveys, thus validating the courageous efforts of the U.S. Army officers and soldiers who were given this monumental task. This lot includes a fascicle of text with the accompanying report by Colonel O. M. Poe.
