At length his movements began to cause some anxiety to the public officers. The United States District Attorney attempted to indict him at Frankfort, Kentucky, but the grand-jury refused to find a bill. Henry Clay defended him in these proceedings, and in reference to his connection with the case, Mr. Parton makes a characteristic display of the spirit in which his book is written, and of his unfitness for the ambitious task he has undertaken. He quotes the following passage from Collins's "Historical Sketches of Kentucky":--"Before Mr. Clay took any active part as the counsel of Burr, he required of him an explicit disavowal, [avowal,] upon his honor, that he was engaged in no design contrary to the laws and peace of the country. This pledge was promptly given by Burr, in language the most broad, comprehensive, and particular. He had no design, he said, to intermeddle with or disturb the tranquillity of the United States, nor its territories, nor any part of them. He had neither issued nor signed nor promised a commission to any person for any purpose. He did not own a single musket, nor bayonet, nor any single article of military stores,--nor did any other person for him, by his authority or knowledge. His views had been explained to several distinguished members of the administration, were well understood and approved by the government. They were such as every man of honor and every good citizen must approve." Upon this paragraph Mr. Parton makes the following extraordinary comments:--"Mr. Clay, there is reason to believe, went to his grave in the belief that each of these assertions was an unmitigated falsehood, and the writer of the above adduces them merely as remarkable instances of cool, impudent lying. On the contrary, with one exception, all of Burr's allegations were strictly true; and even that one was true in a _Burrian_ sense. He did _not_ own any arms or military stores: by the terms of his engagement with his recruits, every man was to join him armed, just as every backwoodsman was armed whenever he went from home. He had _not_ issued nor promised any commissions: the time had not come for that. Jefferson and his cabinet undoubtedly knew his views and intentions, up to the point where they ceased to be lawful."
