SIR: I have the honor to acknowledge the receipt, by the hands of Hon. Mr. Rogers, of your excellency's letter of the 15th instant. Mr. McIntire and the gentlemen with him have been subjected to an examination before Her Majesty's attorney-general of this Province, who has reported to me that the offense of which they stand charged is one rather against the law of nations and of treaties than against those of this Province. They must accordingly be regarded as "state offenders." In this view, their disposal rests exclusively with Her Majesty's Government, to which I shall accordingly report the case. In the meantime I have had pleasure in directing that they shall immediately be allowed to return to the State of Maine upon pledging their parole of honor to present themselves to the Government of this Province whenever Her Majesty's decision may be received, or when required to do so. The high respectability of their characters and situations and my desire to act in all matters relating to the disputed territory in such a manner as may evince the utmost forbearance consistent with the fulfillment of my instructions have influenced me in my conduct toward these gentlemen; but it is necessary that I should upon this occasion distinctly state to your excellency-- First. That if it be the desire of the State of Maine that the friendly relations subsisting between Great Britain and the United States should not be disturbed, it is indispensable that the armed force from that State now understood to be within the territory in dispute be immediately withdrawn, as otherwise I have no alternative but to take military occupation of that territory, with a view to protect Her Majesty's subjects and to support the civil authorities in apprehending all persons claiming to exercise jurisdiction within it. Second. That it is my duty to require that all persons subjects of Her Majesty who may have been arrested in the commission of acts of trespass within the disputed territory be given up to the tribunals of this Province, there to be proceeded against according to law. Third. That in the event of the rumor which has just reached me relative to the arrest, detention, or interruption of James Maclauchlan, esq., the warden of the disputed territory, being correct, that that officer be enlarged and the grounds of his detention explained. Mr. Rogers takes charge of this letter, of which a duplicate will be placed in the hands of the Hon. Mr. McIntire, with both of whom I have conversed and communicated to them my views in regard to the actual position in which I shall be placed and the measures which will be forced upon me if the several demands contained in this letter be not complied with; and I have reason to believe that Mr. McIntire leaves me fully impressed with the anxious desire which I feel to be spared the necessity of acting as the letter of my instructions would both warrant and prescribe.
