"Now, here you have, in the report of a campaign made by an American general eight years before the peace, viz. in 1775, and printed in an English _Annual Register_ five years before the peace, viz. 1799, as direct a reference to the same marked distinction of rivers flowing different ways, in consequence of the peculiar nature of the country, as it is possible to desire; and you have an acknowledgment, _totidem verbis_, that the then known designation of such tract was no other than that used in the article of the subsequent treaty, as it had been also used in the 14th of George III. by the British Legislature and in the Royal proclamation of 1763, and upon examining any map, that of the Useful Knowledge Society or any other, it will be seen that all the rivers rising on the south side of the British boundary do fulfil the terms of the above treaty, and that all on the other, or north side, do, as the above account of Arnold's march expresses it, 'take courses directly contrary.' The rivers on the south side flow towards the Atlantic Ocean, not one on the other side does flow towards it--in itself the most indisputable proof that the American claim cannot stand with those words of the article which assign to them only that tract of territory wherein the rivers flow towards and 'fall into the Atlantic Ocean.' "I may here remark, that as the proclamation of 1763 is the earliest reference I know to these highlands so dividing the rivers, and as that proclamation proceeds from west to east, and as General Arnold found at the west end the peculiar marks required, the only really amicable, and perhaps the only certain, mode of ascertaining the bound, would be not to start on a loose cruise for highlands at the line of St. Croix, which can itself only be determined by its abutment with the specified highlands (in fact, I believe this loose and hand-over-head mode of proceeding has produced all the difficulty), but to start the search where General Arnold crossed, and run the line eastward according to the direction of the rivers, giving all the territory wherein 'the rivers fall into the Atlantic,' as by the treaty, to America, that wherein 'the rivers flow the contrary way' to Britain; for with this report of General Arnold's march seven years before under our view, it is impossible to believe that General Washington would have sanctioned a reference to so marked a distinction as these so-called 'highlands' in one sense, while he meant, in future times, the reference to be interpreted in another. Viewing the matter according to these lights, which is the only just mode of viewing it, as a case between Christians, Penobscot, the cession of which was reprobated in the British Parliament at the time (and when many officers who had been employed in Canada and in the States were present in both Houses), does fulfil the terms required by the treaty--namely, it embraces all the rivers which, rising on the south of Arnold's ridge, flow towards and
