The successor of the murdered President-Andrew Johnson-lost little time in offering (May the 2d) rewards, ranging from $25,000 to $100,000, for the arrest of Jefferson Davis, Jacob Thompson, [The same individual at whose death, in 1885, the Secretary of the Interior, ordered the National flag of the Union--which he had swindled, betrayed, fought, spit upon, and conspired against--to be lowered at halfmast over the Interior Departmental Building, at Washington, D. C.] Clement C. Clay, Beverly Tucker, George N. Sanders, and W. C. Cleary, in a Proclamation which directly charged that they, "and other Rebels and Traitors against the Government of the United States, harbored in Canada," had "incited, concerted, and procured" the perpetration of the appalling crime. On the 10th of May, one of them, Jacob Thompson, from his place of security, in Canada, published a letter claiming to be innocent; characterized himself as "a persecuted man;" arrayed certain suspicious facts in support of an intimation that Johnson himself was the only one man in the Republic who would be benefited by President Lincoln's death; and, as he was found "asleep" at the "unusual hour" of nine o'clock P.M., of the 14th of April, and had made haste to take the oath of office as President of the United States as soon as the breath had left the body of his predecessor, insinuated that he (Johnson) might with more reason be suspected of "complicity" in "the foul work" than the "Rebels and Traitors" charged with it, in his Proclamation; so charged, for the very purpose--Thompson insinuated--of shielding himself from discovery, and conviction! But while, for a moment, perhaps, there flitted across the public mind a half suspicion of the possibility of what this Rebel intimated as true, yet another moment saw it dissipated. For the People remembered that between "Andrew Johnson," one of the "poor white trash" of Tennessee, and the "aristocratic Slave-owners" of the South, who headed the Rebellion, there could be neither sympathy nor cooperation--nothing, but hatred; and that this same Andrew Johnson, who, by power of an indomitable will, self-education, and natural ability, had, despite the efforts of that "aristocracy," forced himself upward, step by step, from the tailor's bench, to the successful honors of alderman and Mayor, and then still upward through both branches of his State Legislature, into the House of Representatives and the Senate of the United States--and, in the latter Body, had so gallantly met, and worsted in debate, the chosen representatives of that class upon whose treasonable heads he poured forth in invective, the gathered hatred of a life-time--would probably be the very last man whom these same "aristocratic" Conspirators, "Rebels, and Traitors," would prefer as arbiter of their fate.
