The examination of witnesses was conducted on the part of the government by the Judge Advocate and by counsel on the part of the accused. The evidence was taken down by short-hand reporters who were sworn to record the evidence faithfully and truly, and not to communicate the same, or any part of the proceedings on the trial, except by authority of the presiding officer. They were required to furnish a copy of the evidence taken each day to the Judge Advocate, and also a copy to prisoners' counsel. No reporters except the official reporters were allowed access to the court-room. The Judge Advocate, however, was allowed to furnish to the agent of the Associated Press, at his discretion, a copy of such testimony and proceedings as might be published during the trial without injury to the public and to the ends of justice. All other publication of the evidence and of the proceedings during the trial was forbidden, and was to be dealt with as a contempt of court. The testimony being closed, the case was to be immediately summed up by one judge advocate, selected by the Judge Advocate General, to be followed or opened, if the Judge Advocate General so selected, by counsel for the prisoners, and the argument closed by one judge advocate. The argument being closed, the court was to proceed immediately to deliberate and make its determination. The provost marshal was required to have the prisoners present during the trial, and was held responsible for their safe keeping. Their counsel was permitted to hold communication with them in the presence, but not in the hearing, of the guard. Counsel for the prisoners were required to furnish immediately a list of witnesses required for the defense of their respective clients to the Judge Advocate General, who procured their attendance in the usual manner.

Surratt asked to introduce Frederick Aiken, Esq., and John W. Clampitt, Esq., as her counsel, which applications were granted by the court. At its meeting on May 12th, David E.
