The justice of "fair play" and the nature of the system can be seen from an analysis of the cases reviewed subsequently in the established courts. As mentioned previously, these cases describe the procedures regarding settlement, land tenure, and ejectment. Although no recorded code of laws has been located, references to "resolutions of the Fair Play men" regularly appear in the depositions and summaries of these cases.[25] According to Leyburn, a customary "law" concerning settlement rights operated on the frontier, particularly among the Scotch-Irish.[26] This "law" recognized three settlement rights: "corn right," which established claims to 100 acres for each acre of grain planted; "tomahawk right," which marked off the area claimed by deadening trees at the boundaries of the claim; and, "cabin right," which confirmed the claim by the construction of a cabin upon the premises. If the decisions of the regular courts are at all indicative, Fair Play settlement was generally based upon "cabin right." However, the frequent allusion to "improvements" implies some secondary consideration to what Leyburn has defined as "corn right." In the case of _Hughes_ vs. _Dougherty_, the significance of "improvements," or "corn rights," vis-a-vis "cabin rights" is particularly noted.[27] The following summary of that case, found in _Pennsylvania Reports_, emphasizes that significance, in addition to defining a Fair Play "code" pertaining to land tenure: THIS was an ejectment for 324 acres of land, part of the Indian lands in _Northumberland_ county. The plaintiff claimed under a warrant issued on the 2d _May_ 1785, for the premises, and a survey made thereon upon the 10th _January_ 1786. The defendant, on the 20th _June_ 1785, entered a caveat against the claims of the plaintiff, and on the 5th _October_ following, took out a warrant for the land in dispute, on which he was then settled. Both claimed the pre-emption under the act of 21st _December_ 1784,[28] and on the evidence given the facts appeared to be: That in 1773, one _James Hughes_, a brother of the plaintiff, settled on the lands in question and made some small improvements. In the next year he enlarged his improvement, and cut logs to build an house. In the winter following he went to his father's in _Donegal_ in _Lancaster_ county, and died there. His elder brother _Thomas_ was at that time settled on the Indian land, and one of the "Fair Play Men," who had assembled together and made a resolution, (which they agreed to enforce as the law of the place,) that "if any person was absent from his "settlement for six weeks he should forfeit his right."
