In March, 1827, Adams warned Gallatin that the sudden and unexpected determination of Great Britain to break off all negotiation concerning the colonial trade, and the contemporaneous interdiction of the vessels of the United States from all British ports in the West Indies, had put a new face on matters. A renewal of the convention of 1818 would probably be agreed to by the Senate, but no concession in the form of a treaty would be acceptable. His words were emphatic. "One inch of ground yielded on the northwest coast,--one step backward from the claim to the navigation of the St. Lawrence,--one hair's breadth of compromise upon the article of impressment would be certain to meet the reprobation of the Senate." In this temper of parties, Adams added, "All we can hope to accomplish will be to adjourn controversies which we cannot adjust, and say to Britain as the Abbe Bernis said to Cardinal Fleuri: 'Monseigneur, j'attendrai.'" But changes now occurred in the British ministry: Lord Liverpool died in February, 1827--Mr. Canning in the following August. Lord Goderich became prime minister. The new administration returned from Canning's eccentric course to the old and quiet path. The commercial convention of 1815 was renewed indefinitely, each party being at liberty to abrogate it at twelve months' notice. The joint occupancy of the Oregon Territory, agreed to in 1818, was continued in a similar manner. On September 29 a convention was signed, referring the northeast boundary to the arbitration of a friendly sovereign. Mr. Gallatin believed that, had Canning lived, he would have opened a negotiation on the subject of impressment. Huskisson considered that 'the right, even if well founded, was one the exercise of which was intolerable, but that this was not the time to take up the subject.' The new British administration did not dare to encounter the clamor of the navy, the opposition of the Tories, and the pride of the nation on this question.
