During his second four years in office, there were more perplexities. Aaron Burr, Vice-President during Jefferson's first term, was tried on the charge of raising an army to place himself on the throne of Mexico, or at the head of a South-western confederacy. England, usually at war with France, had issued orders prohibiting all trade with that country and her allies; Napoleon had retorted by a like measure. Both nations claimed the right to take seamen out of United States vessels. The British frigate Leopard took four seamen by force from the American frigate Chesapeake. The nation seemed on the verge of war, but it was postponed, only to come later, in 1812, under James Madison. Congress passed the Embargo Act, by which all American vessels were detained in our own ports. It had strong advocates and strong opponents, but was repealed as soon as Jefferson retired from office. Owing to these measures our commerce was well-nigh destroyed. At the age of sixty-five years, Jefferson retired to Monticello, "with a reputation and popularity," says Mr. Morse, "hardly inferior to that of Washington." He had had the wisdom never to assume the bearing of a leader. He had been careful to avoid disputes. Once, when riding, he met a stranger, with whom engaging in conversation, he found him bitterly opposed to the President. Upon being asked if he knew Mr. Jefferson personally, he replied, "No, nor do I wish to." "But do you think it fair to repeat such stories about a man, and condemn one whom you do not dare to face?" "I shall never shrink from meeting him if he ever comes in my way." "Will you, then, go to his house to-morrow, and be introduced to him, if I promise to meet you there?" "Yes, I will." The stranger came, to his astonishment found that the man he had talked with was the President himself, dined with him, and became his firm friend and supporter ever afterward. For the next seventeen years, Jefferson lived at Monticello, honored and visited by celebrities from all the world. Sometimes as many as fifty persons stayed at his home over night. One family of six came from abroad, and remained with him for ten months. His daughter Martha, married to Thomas Mann Randolph, presided over his hospitable home, and with her eleven children made the place a delight, for she had "the Jefferson temperament--all music and sunshine." The beautiful Mary, who married her cousin, John W. Eppes, had died at twenty-six, leaving two small children, who, like all the rest, found a home with Jefferson.
