In summary then, it appears that the Treaty of Fort Stanwix in 1768 was responsible for opening the West Branch Valley to settlement, such settlement being stimulated by the opening of the Land Office in Philadelphia on April 3, 1769. James Tilghman, secretary of the Land Office, published the notice of his office's willingness "to receive applications from all persons inclinable to take up lands in the New Purchase."[36] The enthusiasm generated by the opening of the Land Office is shown by the better than 2,700 applications received on the very first day. However, the question of the Tiadaghton came to be a source of real contention. The ambiguity of the Indian references to the western boundary of the first Stanwix Treaty led the eager settlers, who were seeking to legitimize claims in the area between Lycoming and Pine creeks, to favor Pine Creek. There was substance to the settlers' claim. The significance of the boundary question to this study is better understood when it is recognized that the so-called Fair Play system of government in lands beyond the Provincial limits must have a definable locale. It is this writer's firm conviction that Fair Play territory extended from Lycoming Creek, on the north side of the West Branch of the Susquehanna, to the Great Island, some five miles west of Pine Creek. The foundation for the establishment of Lycoming Creek as the Tiadaghton, and consequently, as the eastern boundary of the Fair Play territory is apparent once all the evidence is examined. Aside from the comments of the Indians at the treaty negotiations and Smith's _Laws of the Commonwealth of Pennsylvania_, there are only secondary accounts with little documentation to sustain the Pine Creek argument. On the other hand, the Lycoming Creek claim is buttressed by such primary sources as the journals of Weiser, Bartram, Spangenberg, Ettwein, and Fithian, three of which were written before the location of the Tiadaghton became a subject of dispute. Since none of these men was seeking lands, they can be considered impartial observers. Furthermore, the cartographic efforts of Lewis Evans and John Adlum followed actual visits to the region and say nothing to favor the Pine Creek view. Perhaps the Indians were merely accepting an already accomplished fact at the meeting in 1784. Dr. Paul A. W. Wallace says that this would have been expected from the subservient, pacified Indian. Regardless, the Provincial leadership made no effort to settle the lands in what some called "the disputed territory" until after the later agreement at Stanwix; in fact, they discouraged it.[37] The simple desire for legitimacy gives us very little to go on in the light of more than adequate documentation of the justice of the Lycoming view.
