Soon after Mr. Jefferson entered upon the duties of his second term, a portentous storm darkened the horizon of our country, charged with the lightning of discord. In consequence of being disappointed in riding into the presidency on the whirlwind of confusion he created at the time he was made Vice President and at the end of four years--dropped like a traitor as he was, Aaron Burr mounted upon the tornado of his wild ambition and attempted the formation of a new Republic in the Spanish Provinces on the Mississippi, aiming at an ultimate division, if not dissolution of the Union. He was arrested and tried for high treason but being a man of great foresight, consummate genius and deep cunning--no _overt_ act could be proved against him within the technical meaning of the law and he was acquitted--yet the dark stigma is marked upon the splendor of his brilliant talents in traces so deep, that time nor angels' tears can ever remove it. Like a comet propelled by its own centrifugal force from its constitutional orbit, he fell to rise no more--our country was saved from his Cataline grasp by the Cicero of our nation. About the same time France and Great Britain were at war--both of whom and more especially the latter--had repeatedly insulted the American flag under various but false pretences. Redress was promptly demanded and measures pursued to obtain it. Anxious to preserve peace but determined to vindicate our rights and dignity--Mr. Jefferson simultaneously prosecuted a negotiation and prepared for war. He well understood the importance of the importing and exporting trade to England. Among the means used to bring her to honorable terms, he recommended to Congress the embargo law which was passed on the 22d Dec. 1807. This measure was violently assailed by those opposed to his administration. As he anticipated, it had a salutary effect upon the British government and caused propositions to be made by England for an honorable adjustment of all differences. Thus were the foreign relations of the United States situated when the second term of Mr. Jefferson closed. He then bid a final farewell to public life and consigned the destinies of his beloved country into other hands. He had been an efficient and faithful laborer in the vineyard of American Liberty nearly forty years. He left it richly covered with green foliage and fruit--in the full vigor of health--enclosed by the palisades of truth and honesty--adorned with the crowning glories of philanthropy and patriotism.
