The act of March 12, 1783, gave a clear title to the land, for under Section 6, all rights, titles, or claims to land within the described bounds, whether obtained from the Indians, the late Proprietaries, or any other person or persons, were declared to be null and void, thus reserving the entire tract from sale or settlement until after the allotments to the soldiers were duly made and their claims fully satisfied. By the following section of the act the officers and enlisted soldiers were to be allowed two years after the declaration of peace in which to make their applications, and in event of death occurring before any veteran made his application, an additional year was allowed his heirs, executors or administrators to make application. Thereafter the unlocated tracts were to be disposed of upon such terms as the Legislature might direct. This period for making applications was many times extended, so that no veteran was deprived of a fair opportunity to obtain his tract of the donation land. The authorities of Pennsylvania were even more thoughtful of these Revolutionary veterans, for the General Assembly passed an act which exempted from taxation during lifetime the land which fell to lot of each veteran unless the same was transferred or assigned to another person. Then followed the great purchase of October 23, 1784, and then the Act of March 24, 1785, which directed the manner in which the allowances of land were to be distributed to the troops, and provided for legal titles, vesting in them the right of ownership. A section of the act described the persons who should be entitled to land, and Section 5, in order to comply with a previous resolution of the General Assembly, included the names of Baron Steuben, the German patriot drill master of the Continental Army, who was to receive a grant equal to that of a major general of the Pennsylvania Line, and Lieutenant Colonel Tilghman a grant equal to his rank. Complete lists of all soldiers entitled to land were furnished by the Comptroller General to the Supreme Executive Council, and these claimants were divided into four classes. Upon application of the officers of the Pennsylvania Line, General William Irvine, the commanding officer at Fort Pitt, was appointed agent to explore the lands, as he was well acquainted with all the land appropriated for donation purposes. General Irvine entered upon his duties promptly and seemed to have exercised good judgment. An interesting report of his notes and observations was transmitted to President John Dickinson of the Supreme Executive Council in a letter dated at Carlisle, August 17, 1785. The streams, boundaries and other natural terrain were carefully described, and the general gave a most comprehensive narrative of his every act while on this important tour of duty. Section 8 provided minute directions for the distribution of the tracts by lottery.
