treaty were in force and prior to the Lenape vacating the still inhabited area. To allay the Lenapes' misgivings and suspicions, Penn Land Office Agent and provincial secretary James Logan (1674–1751), had a map produced that misrepresented the farther Lehigh River as the closer Tohickon Creek, and including a dotted line showing a seemingly reasonable path that the "walkers" would take. Satisfied that the land in question was not so terrible a price to honor the old deed, the Lenape signed on, making the now 1737 treaty official. According to the popular account, Lenape leaders assumed that about 40 miles (60 km) was the longest distance that could be covered under these conditions. Provincial Secretary Logan hired the three fastest runners in the colony, Edward Marshall, Solomon Jennings, and James Yeates, to run on a prepared trail. They were supervised during the "walk" by the Sheriff of Bucks County Timothy Smith. The walk occurred on September 19, 1737; only Marshall finished, reaching the modern vicinity of present-day Jim Thorpe, Pennsylvania, 70 miles (113 km) away. At the end of the walk, Sheriff Smith drew a perpendicular line back toward the northeast, and claimed all the land east of these two lines ending at the Delaware River. This resulted in an area of 1,200,932 acres (4,860 km2), only slightly smaller than the size of Rhode Island, located in the modern seven eastern Pennsylvania counties of Pike, Monroe, Carbon, Schuylkill, Northampton, Lehigh and Bucks. The Delaware leaders appealed for assistance to the Iroquois confederacy tribe to the north, who claimed hegemony over the Delaware. The Iroquois leaders decided that it was not in their best interest to intervene on behalf of their southern neighbors, the Delaware since, James Logan had already made a deal with the Iroquois to support the colonial side. As a result, the Lenape had to vacate the Walking Purchase lands. Chief Lappawinsoe, Manawkyhickon, Sassoonan, Nenatcheehunt, and other Lenape leaders continued to protest the arrangement, as the Lenape were forced into the Shamokin and Wyoming River valleys, already crowded with other displaced tribes. Some Lenape later moved further west into the Ohio Country and the southern and western claims of the Kingdom of France in their territory of New France (Quebec), west of the French Fort Duquesne (later Fort Pitt and finally Pittsburgh) at the "Forks of the Ohio". Because of the Walking Purchase, the Lenape grew to distrust
