Jefferson put a generous trust in Burr, and for many years they were intimate correspondents. It is very touching to read, after all that has since happened, such letters as the following, written shortly after the two men had been rival candidates for the presidentship, at a time of unexampled party excitement:--
"Dear Sir--It was to be expected that the enemy would endeavour to sow tares between us, that they might divide us and our friends. Every consideration satisfies me that you will be on your guard against this, as I assure you I am strongly. I hear of one stratagem so imposing and so base, that it is proper I should notice it to you. Mr. Munford, who is here, says he saw at New-York before he left it an original letter of mine to Judge Breckinridge, in which are sentiments highly injurious to you. He knows my handwriting, and did not doubt that to be genuine. I enclose you a copy, taken from a press copy of the only letter I ever wrote to Judge Breckinridge in my life: the press copy itself has been shown to several of our mutual friends here. Of consequence, the letter seen by Mr. Munford must be a forgery; and, if it contains a sentiment unfriendly or disrespectful to you, I affirm it solemnly to be a forgery, as also if it varies from the copy enclosed. With the common trash of slander I should not think of troubling you; but the forgery of one's handwriting is too imposing to be neglected. A mutual knowledge of each other furnishes us with the best test of the contrivances which will be practised by the enemies of both.
"Accept assurances of my high respect and esteem.
In the presidential election of 1800 there were four candidates, Jefferson, Burr, John Adams, and Pinckney. The votes were for Jefferson 73, for Burr 73, for Adams 65, for Pinckney 64. The numbers for Jefferson and Burr being equal, the choice devolved upon the House of Representatives, which voted to attend to no other business till the election was settled, and not to adjourn till the decision was effected. For seven days and nights the ballotting went on, every member being present. Some who were ill or infirm were accommodated with beds and couches, and one sick member was allowed to be attended by his wife. Adams was, as president, on the spot, watching his impending political annihilation. Jefferson was at hand, daily presiding in the Senate. Burr was in the State of New-York, anxiously expecting tidings. The federal party were in despair at having to choose between two republicans (as the democratic party was at that day called). It is said that Hamilton was consulted by his party, and that his advice was to choose Jefferson rather than Burr: a piece of counsel which affected the everlasting destinies of the country, and cost the counsellor his life. At the end of the seven days Jefferson was elected president and Burr vice-president, which office Burr held for a single term, four years.
