A considerable portion, though not the whole, of the official correspondence between the Secretary of State and the other parties to the negotiation is contained in the sixth volume of this collection. The documents published exhibit full proof of the ability with which the argument was conducted. They probably furnish but an inadequate specimen of the judgment, tact, and moral power required to conduct such a negotiation to a successful result. National, State, and individual susceptibilities were to be respected and soothed; adverse interests, real or imaginary, to be consulted; the ordeal of the Senate to be passed through, after every other difficulty had been overcome; and all this in an atmosphere as little favorable to such an operation as can well be imagined. What neither Mr. Monroe in the "era of good feelings," nor the ability and experience of Messrs. Adams, Clay, and Gallatin, nor General Jackson's overwhelming popularity, had been able to bring about, was effected under the administration of Mr. Tyler, though that administration seemed already crumbling for want of harmony between some of the members and the head, and between that head and the party which had brought him into power. No higher tribute can be paid to the ability and temper which were brought to the work. It was, however, in truth, an adjustment equally honorable and advantageous to all parties. There is not an individual of common sense or common conscience in Maine or Massachusetts, in the United States or Great Britain, who would now wish it disturbed. It took from Maine a tract of land northwest of the St. John, which the people of Maine believed to belong to them under the treaty of 1783. But it is not enough that we think ourselves right; the other party thinks the same; and when there is no common tribunal which both acknowledge, there must be compromise. The tract of land in question, for any purpose of cultivation or settlement, was without value; and had it been otherwise, it would not have been worth the cost of a naval armament or one military expedition, to say nothing of the abomination of shedding blood on such an issue. But the disputed title to the worthless tract of morass, heath, and rock, covered with snow or fog throughout a great part of the year, was not ceded gratuitously. We obtained the navigation of the St. John, the natural outlet of the whole country, without which the territory watered by it would have been of comparatively little value; we obtained a good natural boundary as far as the course of the river was followed; and we established the line which we claimed at the head of the Connecticut, on Lake Champlain, and on the upper lakes; territorial objects of considerable interest. Great Britain had equal reason to be satisfied with the result. For her the territory northwest of the St. John, worthless to us, had a geographical and political value; it gave her a convenient connection between her provinces, which was all she desired.
