I urge this course, at the present moment, from deep conviction of its importance. And be assured, Sir, whatever the final determination of this Convention, there are many here to-day who will never yield support to any candidate, for Presidency or Vice-Presidency, who is not known to be against the extension of Slavery, even though he have freshly received the sacramental unction of a "regular nomination." We cannot say, with detestable morality, "Our party, _right or wrong_." The time has gone by when gentlemen can expect to introduce among us the discipline of the camp. Loyalty to principle is higher than loyalty to party. The first is a heavenly sentiment, from God: the other is a device of this world. Far above any flickering light or battle-lantern of party is the everlasting sun of Truth, in whose beams are the duties of men. THE LATE HENRY WHEATON. ARTICLE IN THE BOSTON DAILY ADVERTISER, MARCH 16, 1848. The death of a person like Mr. Wheaton naturally arrests attention,--even at this period of funereal gloom, when the Angel of Death has overshadowed the whole country with his wings. He was long and widely known in official relations, devoted for many years to the service of his country, studious always of literature and jurisprudence, illustrious as a diplomatist and expounder of the Law of Nations,--with a private character so pure as to make us forget, in its contemplation, the public virtues by which his life was elevated. He died after a brief illness, accompanied by a disease of the brain, on Saturday evening, March 11, 1848, at Dorchester. On that day the remains of John Quincy Adams, who, as President of the United States, first advanced Mr. Wheaton to a diplomatic place in the service of his country,--after a long procession, through mourning towns and cities, from the Capitol, which had been the scene of his triumphant death,--were brought to their final resting-place in the adjoining town of Quincy. The faithful friend and servant thus early followed his venerable chief to the fellowship of another world. The principal circumstances in Mr. Wheaton's life may be briefly told. He was born at Providence, on the 27th of November, 1785, and was a graduate of Brown University, in 1802. After admission to the bar, he visited Europe, particularly the Continent, where his mind thus early became imbued with those tastes which occupied so much of his later years. Some time after his return, finding little inducement to continue the practice of the law in Providence, he removed to New York. This was in 1812. Here he became the editor of an important journal, "The National Advocate,"--a paper afterwards merged in "The Courier and Inquirer." His experience in this character closed May 15, 1815. As a journalist, he is reputed to have been uniformly discreet, decorous, and able, at a time when the fearful trials of war, in which the country was engaged, added to the responsibilities of his position.
