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.
