Early Virginia Railroad survey map of the area between the Shenandoah and Potomac Rivers, published in a government survey.
The map is drawn from the original by Lt. Andrew Atkinson Humphreys and based on surveys by Lts. A.D. Mackay and E. French in 1831 and Lts. French and J.F. Izard in 1832.This rail line was designed to divert Shenandoah Valley wheat from Alexandria and stimulate growth in Baltimore.
The topographic map illustrates an area between the Shenandoah and Potomac Rivers to Winchester. It locates Harper's Ferry, Charleston, Smithfield Village, Winchester, and scores of individual farms with the owner's name. It shows mills, distilleries, blacksmith shops, etc. along the proposed routes. Across the bottom is an extensive table giving a summary of the routes surveyed.
