Booth was an actor, and the son of a well known actor; and the son had inherited, apparently, much of the reckless and occasionally furious temper of his father. He was also a very violent and bitter rebel. During the fall of 1864, he had been in Canada, consulting with the rebel agents there, and mixed up with a number of other subordinate agents in the business of assassinating President Lincoln; and he was the most prominent candidate, so to speak, for the place of actual murderer. On November 11th, 1864, he was in New York, where, while riding with a companion in a street car, he dropped a letter which came into the possession of the government; it was a vigorous appeal to him to assassinate Mr. Lincoln. It said: "Abe must die, and now. You can choose your weapons, the cup, the knife, the bullet;" and again: "Strike for your home, strike for your country; bide your time, but strike sure." During the winter, Booth was engaging the assistance required for his scheme; and he had already fixed upon the scene of the murder; for, not later than January, he was urging one Chester to enter into the plan, and assuring him that all his part of it would be to stand at the back door of Ford's Theatre and open it. This was a safe calculation, for the President's enjoyment of dramatic performances was great, and enhanced by the difficulty of finding agreeable relaxations, and also by the awful pressure of his official duties and of the war, which intensified the need of relaxation. The scheme as finally arranged, provided for the assassination of Mr. Lincoln, by Booth; of Mr. Johnson, by Atzerodt; of Mr. Seward, by Payne, (alias Powell); and of Gen. Grant, by O'Laughlin. For the President, an elaborate death trap was constructed in Ford's Theatre. The catches of the locks to all three doors of the President's box (one outer and two inner ones), were loosened by loosening their screws, and left so that a slight push would enable the assassin to enter even though the doors should be locked. A small hole was made through one of the two inner ones, to enable him to see before entering exactly how his victim sat, so that the final moves within the box could be laid out before entering it; and a wooden brace was prepared to set against the outer door (which opened inward) with one end, and with the other to fit a mortice cut in the wall behind, so that after entering, the assassin could fasten the door behind him sufficiently to prevent any interruption until his work was done. Arrangements were made for securing horses for the murderers to flee with. The stage carpenter or assistant, Spangler, was employed to be on hand and open and shut the back door of the theatre when wanted. Some scenes and miscellaneous matter that frequently impeded more or less the passage from the front of the stage to this back door, were piled up or otherwise put out of the way. A supply of weapons for the conspirators was provided. And a
