Of these commissions two have already terminated their sessions and investigations, one by entire and the other by partial agreement. The commissioners of the 5th article of the treaty of Ghent have finally disagreed, and made their conflicting reports to their own Governments. But from these reports a great difficulty has occurred in making up a question to be decided by the arbitrator. This purpose has, however, been effected by a 4th convention, concluded at London by the plenipotentiaries of the two Governments on September 29th, 1827. It will be submitted, together with the others, to the consideration of the Senate. While these questions have been pending incidents have occurred of conflicting pretensions and of dangerous character upon the territory itself in dispute between the two nations. By a common understanding between the Governments it was agreed that no exercise of exclusive jurisdiction by either party while the negotiation was pending should change the state of the question of right to be definitively settled. Such collision has, never the less, recently taken place by occurrences the precise character of which has not yet been ascertained. A communication from the governor of the State of Maine, with accompanying documents, and a correspondence between the Secretary of State and the minister of Great Britain on this subject are now communicated. Measures have been taken to ascertain the state of the facts more correctly by the employment of a special agent to visit the spot where the alleged outrages have occurred, the result of those inquiries, when received, will be transmitted to Congress. While so many of the subjects of high interest to the friendly relations between the two countries have been so far adjusted, it is a matter of regret that their views respecting the commercial intercourse between the United States and the British colonial possessions have not equally approximated to a friendly agreement. At the commencement of the last session of Congress they were informed of the sudden and unexpected exclusion by the British Government of access in vessels of the United States to all their colonial ports except those immediately bordering upon our own territories. In the amicable discussions which have succeeded the adoption of this measure which, as it affected harshly the interests of the United States, became subject of expostulation on our part, the principles upon which its justification has been placed have been of a diversified character. It has been at once ascribed to a mere recurrence to the old, long established principle of colonial monopoly and at the same time to a feeling of resentment because the offers of an act of Parliament opening the colonial ports upon certain conditions had not been grasped at with sufficient eagerness by an instantaneous conformity to them.
