Who were the persons concerned in the assassination of President Lincoln, has never been judicially proved. Perhaps it never will be. The indictment against the conspirators named the following parties. David E. Herold, George A. Atzerodt, Lewis Payne, Michael O'Laughlin, Edward Spangler, Samuel Arnold, Mary E. Surratt, Samuel A. Mudd, John H. Surratt, John Wilkes Booth, Jefferson Davis, George N. Sanders, Beverly Tucker, Jacob Thompson, William C. Cleary, Clement C. Clay, George Harper, and George Young; and it added, "and others unknown." The assassin was John Wilkes Booth. And whether or no Jefferson Davis and his fellows in the rebel government were actually aiding and abetting in this particular crime, it has not been unjust nor unnatural to suspect them of it. For Mr. Davis certainly accredited Thompson, Sanders, Clay, and Tucker, as his official agents in Canada. These men in their turn, and acting in harmony with their instructions and the purposes of their government, gave a commission to that John A. Kennedy who was detected in attempting to kindle an extensive fire in the city of New York, and consulted with him about his proposed plans. This was the substance of Kennedy's own confession, and he and his accomplices did kindle fires in four of the New York hotels. It is completely proved, again, that Davis paid sundry sums, in all $35,000 in gold, to incendiaries hired by his government to burn hospitals and steamboats at the West, and that Thompson paid money to a person engaged in Dr. Blackburn's attempt to spread yellow fever in our cities.
