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.
