Pennsylvania Assembly so that it could make war requisitions. On October 9, 1736, he responded to requests from Native American leaders to control the sale of alcohol, which was creating serious social problems, by prohibiting the sale of rum in indigenous communities, but as the penalty was only a fine of ten pounds and the law was poorly enforced, it did not have a significant effect. During his tenure as acting governor, Logan played an active role in the territorial expansion of the colony. Whereas William Penn and his immediate successors had pursued a policy of friendly relations with the Leni Lenape (Delaware) peoples, Logan and other colony proprietors (notably the indebted brothers John, Richard and Thomas Penn) pursued a policy of land acquisition. Such efforts to expand were spurred by increased immigration to the colony and fears that the New York Colony was infringing on Pennsylvania's northern borders in the Upper Delaware river valley. In addition, many proprietors (including Logan and the Penn brothers) had engaged in extensive land speculation, selling off lands occupied by the Lenape to new colonists before concluding an official treaty with the tribe. As part of his efforts to expand Pennsylvania, Logan signed the Walking Treaty of 1737 (commonly referred to as the Walker Purchase) with the Lenape, forcing the tribe to vacate lands in the Upper Delaware and Lehigh valleys under the auspices of the tribe having committed to sell the lands to William Penn in 1686—a treaty whose ratifying document is considered by some sources to have been a fabrication. Under the terms of the treaty, the Lenape agreed to cede as much territory as a man could walk in one and one-half days to the Pennsylvania colony; however, Logan used the treaty's vague wording, the Lenape's unclear diplomatic status, and a heavily influenced (scouts were sent ahead to clear the path of the runners selected to represent the colony) "walk" to claim a much larger territory than was originally expected by the Lenape. Meanwhile, Logan negotiated (in advance) with the powerful Iroquois Confederacy to allow for the treaty to take place. As a result, the Iroquois (nominally the diplomatic overlords and protectors of the Lenape people) rebuffed Lenape attempts to have the Iroquois intervene on their behalf. The net result of the Walking Treaty was an increase in the colony's size of over 1,200,000 acres, but unintended scattering of the Lenape
