Whereas, the honourable John Penn, Esquire, then Governor of the late province, now state of Pennsylvania, did, on the twenty-fourth day of October, in the year one thousand seven hundred and seventy-four, nominate and appoint David Rittenhouse, Esquire, on the part of Pennsylvania, to fix, in conjunction with any person to be appointed on the part of the then province of New York, the beginning of the forty-third degree of north latitude on the Mohawk or western branch of Delaware river, which is the north-east corner of Pennsylvania, and to proceed westward in fixing and marking the boundary line between the said provinces of Pennsylvania and New York: And whereas, the honourable Cadwallader Colden, Esquire, then governor of the late province, now state, of New York, with the advice of the then council, did, on the eighth day of November, in the same year, nominate and appoint Samuel Holland, Esquire, on the part of New York, to fix, in conjunction with the said David Rittenhouse, the same corner, and to proceed in running and marking the said line: And whereas, by virtue of an act of the general assembly of the state of Pennsylvania, the supreme executive council of this commonwealth, by commission, under the hand of Charles Biddle, Esquire, and the great seal, bearing date the sixteenth day of June, one thousand seven hundred and eighty-six, did constitute and appoint Andrew Ellicot, Esquire, commissioner, on the part of the said commonwealth of Pennsylvania, to run and mark the northern boundary of this commonwealth: And whereas, the said David Rittenhouse and Samuel Holland, in pursuance of their said respective appointments, did proceed on the said business, and made return thereof, under their hands, bearing date at Philadelphia the fourteenth day of December, in the same year, by which it appears that they ascertained and fixed the beginning of the forty-third degree of north latitude on the said Mohawk or western branch of Delaware, and there, in a small island of the said river, planted a stone, marked with the letters and figures NEW YORK, 1774, cut on the north side thereof, and the letters and figures Lat. 40° Var. 4°20′ cut on the top thereof; and in a direction due west from thence, on the west side of the said branch of Delaware, collected and placed a heap of stones at the water mark, and proceeding further west, four perches, planted another stone in the said line, marked with the letters and figures PENNSYLVANIA, 1774, cut on the south side thereof, and the letters and figures Lat. 42° Var. 4°20′ cut on the top thereof; and at the distance of eighteen perches due west from the last mentioned stone marked an ash tree; but that the rigour of the season prevented them from proceeding further in running the said line, as by the said return, remaining of record, fully appears: And whereas, by virtue of an act of the general assembly of the state of New York, entitled “An act for running out and marking the jurisdiction line between this state and the commonwealth of Pennsylvania,” passed the 26th day of February, in the year one thousand seven hundred and eighty-six, James Clinton and Simeon Dewitt, Esquires, were duly appointed commissioners, on the part of the state of New York, to join with such person or persons as should be appointed on the part of Pennsylvania, to run out, mark and ascertain the said line, beginning at the place so fixed and ascertained by the said commissioners, as above-mentioned, on the Mohawk or western branch of Delaware river: And whereas, the said Andrew Ellicot, on the part of this commonwealth, and the said James Clinton and Simeon Dewitt, on the part of the state of New York, did, in the year of our Lord one thousand seven hundred and eighty-six and seven, in pursuance of the powers so as aforesaid vested in them, run, fix and ascertain the said boundary line, beginning at the first mentioned stone, marked as is herein above recited, and extending thence due west by a line of mile-stones, marked with the number of mile and miles which each stone is distant from the said first mentioned stone, planted in the said small island, to the bank of Lake Erie, at the distance of two hundred and fifty-nine miles and eighty-eight perches from the said first mentioned corner stone; and the said commissioners did accordingly return a draft or plot of the said line, under their hands, to the Supreme Executive Council of this commonwealth; in which said draft or plot are noted and laid down the several principal waters, mountains, and other remarkable places, through and over which the said boundary line runs; which said boundary line is and ought to be for ever hereafter deemed and taken as the true boundary of territory and jurisdiction between this state and the state of New York, so far as the state of New York is bounded thereby:
