Col. H. L. BURNETT, _Judge Advocate_, Cincinnati, Ohio:-- COLONEL:--I stated before the Commission at Washington that I commenced to board with Mrs. Surratt in November, 1864. As a general thing I remained at home during the evenings, and consequently I heard many things which were then intended to blind me, but which now are as clear as daylight. The following facts, which have come to my recollection since the renditon of my testimony, may be of interest:-- AFFIDAVIT OF LOUIS J. WIECHMANN. I once asked Mrs. Surratt what her son John had to do with Dr. Mudd's farm; why he made himself an agent for Booth? (She herself had told me that Booth desired to purchase Mudd's farm.) Her reply was, that Dr. Mudd and the people of Charles County had got tired of Booth, and that they had pushed him on John. Before the 4th of March she was in the habit of remarking that _something_ was going to happen to "Old Abe" which would prevent him from taking his seat; that General Lee was going to execute a movement which would startle the _whole world_. What that movement was she never said. A few days after I asked her why John brought such men as Herold and Atzerodt to the house, and why he associated with them? "Oh, John wishes to make use of them for his _dirty work_," was her reply. On my desiring to know what the dirty work was, she answered that "John wanted them to clean his horses." He had two at that time. And once, when she sent me to Brooks, the stable keeper, to inquire about her son, she laughed, and remarked that "Brooks considered John H. Surratt and Booth and Herold and Atzerodt a party of young gamblers and sports, and that she wanted him to think so." Brooks has told me since the trial that such was actually the case, and that at one time he saw John H. Surratt with three one-hundred-dollar notes in his possession.
