One of the earliest printed government surveys that was drawn from the original plot by Lt. Andrew Atkinson Humphreys, based on surveys by Lts. A.D. Mackay and E. French in 1831 and Lts. French and J.F. Izard in 1832. It charts an area between the Shenandoah and Potomac Rivers to Winchester, locating Harper's Ferry, Charleston, Smithfield Village, Winchester, and scores of individual farms; 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.
