Booth had left the side of his companion before this long enough to go into the saloon, where he drank a glass of whiskey, and then, as soon as the time had been called the third time, went at once into the theatre, and in less than ten minutes thereafter fired the fatal shot. It is evident that it had been arranged between Booth and Payne that the assassination of Secretary Seward should be concurrent with that of President Lincoln; and that a system of signals had been arranged, of which the man who called the time was acting as monitor. The suspicions of Sergeant Dye having been aroused by the conduct of these three men, he naturally scanned them very closely, and testified that he had a good view, not only of the person, but of the face and features of the man who called the time, and had his image indelibly impressed on his memory. Upon being confronted by Surratt on his trial, he unhesitatingly and positively declared that he was the man. In addition to Reed and Dye, who testified before the Commission, there were nine others who testified on the trial of Surratt to having seen him that day in the City of Washington. All of these persons, except four, were personally acquainted with him, and could not have been mistaken, as they were able to give the time of day when, and the place where, they saw him, as also, in the case of most of them, to describe his person, dress, hat, moustache, etc., etc., without any discrepancies in their testimony. The other four, though not acquainted with him, identified him before the jury, more or less positively, as the man they had seen. It is worthy of remark that though they all testified with more or less of particularity in their descriptions of his person, his dress, his hat, his moustache, and as to the time of day when, and the place where, they had seen him, there was nothing incongruous or contradictory in their testimony. One witness, a colored woman, Susan Ann Jackson, who was in service at Mrs. Surratt's at the time, and had been for three or four weeks previous to the assassination, testified that under the direction of Mrs. Surratt she had made tea for the prisoner after the family and boarders had left the table on the night of the assassination, and that Mrs. Surratt had said to her on that occasion, "This is my son," and had asked her if he did not look like Annie. She said this was the first and only time she had seen him until she met him on his trial, and then she positively identified him as the man she had waited upon that night. The time was impressed on her memory by its being Good Friday, and the night of the assassination. Several of the witnesses who testified to his presence in the city on that day also testified that they saw him in company with Booth, and one, at least, with Booth and O'Laughlin. Surratt himself told his old acquaintance, St. Marie, with whom he renewed his acquaintanceship in the ranks of the Papal Zouaves at Velletri, in Italy, that he left
