You will see by the accompanying papers (and I take great pleasure in communicating the fact) that Mr. McIntire and his assistants have been released. It was, however, upon their parole of honor to return when thereto required by the government of that Province. Immediately upon the receipt of this information I advised the release of James Maclauchlan, esq., provincial land agent, and his assistant, _upon the same terms_. Since my last communication the land agent's forces at the Aroostook have been reenforced by about 600 good and effective men, making the whole force now about 750. I have a letter from Mr. Jarvis dated the 19th, before the reenforcement had arrived, and when his company consisted of only 100 men. He says he found the men in good spirits and that they had been active in making temporary but most effectual defenses of logs, etc. After describing his defenses, he says: "By to-morrow noon a force of 100 men would make good our position against 500. _Retreating, therefore, is out of the question_. We shall make good our stand against any force that we can reasonably expect would be brought against us." He says further: "I take pleasure in saying to you that a finer looking set of men I never saw than those now with me, and that the honor of our State, so far as they are concerned, is in safe-keeping." The draft of 1,000 men from the third division has been made with great dispatch. The troops, I understand, arrived promptly at the place of rendezvous at the time appointed in good spirits and anxious for the order to march to the frontier. The detachment from this second division will be ordered to march at the earliest convenient day--probably on Monday next. Other military movements will be made, which it is unnecessary to communicate to you at this time. The mission of Colonel Rogers to the lieutenant-governor of New Brunswick has resulted successfully so far as relates to the release of the land agent and his assistants, and has been conducted in a manner highly satisfactory. JOHN FAIRFIELD. [Memorandum.] WASHINGTON, _February 27, 1839_. Her Majesty's authorities consider it to have been understood and agreed upon by the two Governments that the territory in dispute between Great Britain and the United States on the northeastern frontier should remain exclusively under British jurisdiction until the final settlement of the boundary question.
