Among others who came to assist our progress and adorn our history was that eminent lawyer and patriot--that good and pure man whose monument stands beside St. Paul's Church, on Broadway, and may be considered as pointing its white finger to heaven in appeal against the severe doctrines under which these prisoners are sought to be punished. I refer to THOMAS ADDIS EMMETT. In 1806, two men, Smith and Ogden, were put upon trial, charged with aiding Miranda and the people of Caraccas to effect a revolt against the Government of Spain, which, it was said, was at peace with the United States. They were indicted under a statute of the United States; and if it had turned out on the trial that the United States was certainly in a condition of peace with Spain, they might have been convicted. However, that was a question of fact left to the Jury. The learned Judges, pure and able men, entertained views very hostile to the notions of the accused, and were quite as decided in those views as his honor Judge Grier in the summary disposition he made of the so-called pirates in Philadelphia. The trial came on, and, with the names of the Jurors on that trial, there are preserved to us the names of Counsel, whose career is part of history. Among them were NATHAN SANFORD, PIERPOINT EDWARDS, WASHINGTON MORTON, CADWALLADER D. COLDEN, JOSIAH OGDEN HOFFMAN, RICHARD HARRISON, and MR. EMMETT, already named. Well, there was an effort made to disparage any such enterprise as Miranda's, and any such aid thereto as the accused were charged with giving. The Counsel endeavored to prove that the intent was a question of law, and the fact had nothing to do with it. COLDEN, in his argument, said, "Gentlemen, all _guilt_ is _rooted in the mind_, and _if not to be found there, does not exist, and whoever will contend against the proposition_ MUST FIGHT AGAINST HUMAN NATURE, AND SILENCE HIS OWN CONSCIENCE." We do not often find an opportunity, gentlemen, to regale ourselves with anything that emanated from the mind of Mr. Emmett. It is peculiar to the nature of his profession that most of what the advocate says passes away almost at the moment of its utterance. When Mr. Emmett comes to allude to the disfavor sought to be thrown on revolutionary ideas by the eminent counsel for the prosecution, he says: "In particular, I remember, he termed Miranda a fugitive on the face of the earth, and characterized the object of the expedition as something audacious, novel, and dangerous. It has often struck me, gentlemen, as matter of curious observation, how speedily new nations, like new made nobility and emperors, acquire the cant and jargon of their station.
