William Pitt Fessenden was chairman on the part of the Senate and Thaddeus Stevens was chairman of the part of the House. Upon the death of Mr. Stevens I succeeded to his place. The testimony taken in these cases fills three huge volumes. No inconsiderable part of the testimony was taken by myself, and I was but seldom absent from the meetings of the committees. JOHN WILKES BOOTH In no other situation in life is the character of a man more fully and truthfully brought into view than when he is placed upon the witness- stand and subjected to an examination by counsel or others who aim to support opposite opinions and to reach adverse results. The committees that conducted the investigations were composed of men who entertained opposite views in regard to the reconstruction of the government and in regard to the impeachment of President Johnson. There was also a difference of opinion upon the question of the responsibility of the Confederate authorities for the assassination of Mr. Lincoln. As a consequence of this diversity of opinion the witnesses were subjected to the equivalent of a cross-examination in a court of justice. Some of the impressions of men that I received in the many hearings, and some of the opinions I formed, are recorded here. In each branch of these comprehensive inquiries there may be found something in the nature of evidence that may appear to have a bearing upon the assassination of Mr. Lincoln. It is my purpose in these paragraphs to bring in to view the testimony which relates directly to John Wilkes Booth, the most conspicuous and without question the chief criminal in the tragedy of the assassination of President Lincoln, and the attempt upon the life of Mr. Seward. The first step in the proceedings which culminated in the murder was the deposit at Surrattsville (a place about five miles from Washington, and owned by the Surratt family) of a carbine, two bottles of whiskey, a small coil of rope, a field glass, a monkey wrench, and some other articles. The house was kept by a man named Lloyd, and neither the character of the house nor that of the keeper could bear a rigid test in ethics. The deposit was made about the first of March by John H. Surratt, Atzerodt and David E. Herold, all of whom were afterwards implicated in the crime. The articles were received and secreted by Lloyd, but only after objections by him, as appears from his testimony. Lloyd connected Mrs. Surratt with the crime by these facts as related by him. She called upon Lloyd the Tuesday preceding the fatal Friday and gave him this message: "She told me to have them ready (speaking of the shooting-iron) that they would be called for or wanted soon, I have forgotten which."
