After the inauguration of General Taylor as President, General Scott, between whom and the President there was no very good feeling, continued his headquarters in New York; but when President Fillmore succeeded, in 1850, he removed to Washington, and continued to reside in the latter city until the accession of President Pierce, when, by General Scott's request, there was another change back to New York, where until 1861--with the exception of ten months of hard duty--he remained and maintained headquarters of the army. In 1849 there were evidences of discontent which almost assumed the attitude of threats in the Canadas growing out of political agitation, and General Scott was interrogated on the question of the advisability of annexation by John C. Hamilton, Esq., of New York. General Scott replied from West Point, June 29, 1849, in which he expressed the opinion that the news from the British Parliament would increase the discontent of the Canadas, and that those discontents might in a few years lead to a separation of the Canadas, New Brunswick, etc., from England. He thought that, instead of those provinces forming themselves into an independent nation, they would seek a connection with our Union, and that thereby the interests of both sides would be promoted, the provinces coming into the Union on equal terms with the States. This would secure the free navigation of the St. Lawrence River, which would be of immense importance to at least one third of our population, and of great value to the remainder. Although opposed to incorporating with us any district densely populated with the _Mexican_ race, he would be most happy to fraternize with our Northern and Northeastern neighbors.
