The spell was broken by the practical promptings of common sense. Not in possession, but only in pursuit of a treasury and a scepter, the would-be monarch addressed himself to the solution of his complicated problem. It was necessary to learn how the Louisianians regarded the Federal government, how much prejudice they felt against the Atlantic States, and whether they could be influenced to break away from the Union and to organize a separate autonomy. Burr wished further to know who and how many were disposed to wage war against the Spaniards with the ulterior design of conquering Mexico. In order to learn the inside facts he must gain the confidence of all, must make himself popular, must fathom hearts and steal away brains. The final success of his plans would depend on the good-will of the people. The good-will of the people must be won by address--by social tact. Social tact was Aaron Burr's art of arts. He deliberately set about the delicate business of captivating a city that he might eventually capture it. Wilkinson had pressed upon him letters of introduction to the magnates of the town. Neither letters nor formal receptions were needed to introduce Aaron Burr to society. His manner was passport, entitling him to cross all borders; his sympathy was cosmopolitan, his toleration unlimited, his pleasure, to please others, his study urbanity. Jews thought him a Hebrew, and Christians voted him orthodox. The amiable but capricious creoles, easy to take offense, yet blind in their devotion to those they confide in, swarmed to his standard. The Roman Catholic bishop countenanced him, endorsed his aims, and signalized an official friendliness by accompanying him on a visit to the Ursuline Convent, and there the son of a Protestant preacher chatted pleasantly with my lady prioress and her demure nuns. Burr went everywhere, and wherever he went, he made discreet use of his opportunity to inquire, to observe, to listen, to make friends and proselytes. He felt the pulse of public sentiment. Never to any person did he fully disclose his designs. Without argument or appeal, he convinced, persuaded, and inflamed the victims of his corrupting influence. To the avaricious his intimations promised riches; to the luxurious, pleasure; to those disaffected towards the East, revolt and secession.
