Always aiming at an amicable adjustment of the dispute, both parties have entertained and repeatedly urged upon each other a desire that each should exercise its rights, whatever it considered them to be, in such a manner as to avoid collision and allay to the greatest practicable extent the excitement likely to grow out of the controversy. It was in pursuance of such an understanding that Maine and Massachusetts, upon the remonstrance of Great Britain, desisted from making sales of lands, and the General Government from the construction of a projected military road in a portion of the territory of which they claimed to have enjoyed the exclusive possession; and that Great Britain on her part, in deference to a similar remonstrance from the United States, suspended the issue of licenses to cut timber in the territory in controversy and also the survey and location of a railroad through a section of country over which she also claimed to have exercised exclusive jurisdiction.
The State of Maine had a right to arrest the depredations complained of. It belonged to her to judge of the exigency of the occasion calling for her interference, and it is presumed that had the lieutenant-governor of New Brunswick been correctly advised of the nature of the proceedings of the State of Maine he would not have regarded the transaction as requiring on his part any resort to force. Each party claiming a right to the territory, and hence to the exclusive jurisdiction over it, it is manifest that to prevent the destruction of the timber by trespassers, acting against the authority of both, and at the same time avoid forcible collision between the contiguous governments during the pendency of negotiations concerning the title, resort must be had to the mutual exercise of jurisdiction in such extreme cases or to an amicable and temporary arrangement as to the limits within which it should be exercised by each party. The understanding supposed to exist between the United States and Great Britain has been found heretofore sufficient for that purpose, and I believe will prove so hereafter if the parties on the frontier directly interested in the question are respectively governed by a just spirit of conciliation and forbearance. If it shall be found, as there is now reason to apprehend, that there is, in the modes of construing that understanding by the two Governments, a difference not to be reconciled, I shall not hesitate to propose to Her Britannic Majesty's Government a distinct arrangement for the temporary and mutual exercise of jurisdiction by means of which similar difficulties may in future be prevented.
But between an effort on the part of Maine to preserve the property in dispute from destruction by intruders and a military occupation by that State of the territory with a view to hold it by force while the settlement is a subject of negotiation between the two Governments there is an essential difference, as well in respect to the position of the State as to the duties of the General Government. In a letter addressed by the Secretary of State to the governor of Maine on the 1st of March last, giving a detailed statement of the steps which had been taken by the Federal Government to bring the controversy to a termination, and designed to apprise the governor of that State of the views of the Federal Executive in respect to the future, it was stated that while the obligations of the Federal Government to do all in its power to effect the settlement of the boundary question were fully recognized, it had, in the event of being unable to do so specifically by mutual consent, no other means to accomplish that object amicably than by another arbitration, or by a commission, with an umpire, in the nature of an arbitration; and that in the event of all other measures failing the President would feel it his duty to submit another proposition to the Government of Great Britain to refer the decision of the question to a third power. These are still my views upon the subject, and until this step shall have been taken I can not think it proper to invoke the attention of Congress to other than amicable means for the settlement of the controversy, or to cause the military power of the Federal Government to be brought in aid of the State of Maine in any attempt to effect that object by a resort to force.
On the other hand, if the authorities of New Brunswick should attempt to enforce the claim of exclusive jurisdiction set up by them by means of a military occupation on their part of the disputed territory, I shall feel myself bound to consider the contingency provided by the Constitution as having occurred, on the happening of which a State has the right to call for the aid of the Federal Government to repel invasion.
I have expressed to the British minister near this Government a confident expectation that the agents of the State of Maine, who have been arrested under an obvious misapprehension of the object of their mission, will be promptly released, and to the governor of Maine that a similar course will be pursued in regard to the agents of the Province of New Brunswick. I have also recommended that any militia that may have been brought together by the State of Maine from an apprehension of a collision with the government or people of the British Province will be voluntarily and peaceably disbanded.
I can not allow myself to doubt that the results anticipated from these representations will be seasonably realized. The parties more immediately interested can not but perceive that an appeal to arms under existing circumstances will not only prove fatal to their present interests, but would postpone, if not defeat, the attainment of the main objects which they have in view. The very incidents which have recently occurred will necessarily awaken the Governments to the importance of promptly adjusting a dispute by which it is now made manifest that the peace of the two nations is daily and imminently endangered. This expectation is further warranted by the general forbearance which has hitherto characterized the conduct of the Government and people on both sides of the line. In the uniform patriotism of Maine, her attachment to the Union, her respect for the wishes of the people of her sister States (of whose interest in her welfare she can not be unconscious), and in the solicitude felt by the country at large for the preservation of peace with our neighbors, we have a strong guaranty that she will not disregard the request that has been made of her.
As, however, the session of Congress is about to terminate and the agency of the Executive may become necessary during the recess, it is important that the attention of the Legislature should be drawn to the consideration of such measures as may be calculated to obviate the necessity of a call for an extra session. With that view I have thought it my duty to lay the whole matter before you and to invite such action thereon as you may think the occasion requires.
