About one o'clock on that afternoon, Lieutenant Dana, with a squad of cavalry, passed down toward Bryantown in pursuit of Booth, and as there was no doubt a sharp look-out kept from the house of Dr. Mudd, which stood about a quarter of a mile from, and in full view of, the road, they were by this admonished of their danger and resumed their flight as soon as they could after the soldiers passed. Thus Mudd got them off of his hands, and started them on their way to his friend, Samuel Cox. On Tuesday, the 18th of April, Mudd was first interviewed, and then denied that there had been any body at his house on the 15th; but upon being pressed with questions, he finally said that two strangers had come to his house about four o'clock on Saturday morning on horseback, one of them having a broken leg, and that he had taken them in, dressed the leg, and had a crutch made for the man, and that they had left after breakfast, telling in what direction they had gone, but giving a false cue. He denied knowing either of them, and said they were entire strangers to him, going on to give a minute description of the men and their horses as though desirous of giving all the information he could, but with an appearance and manner that created distrust. Being asked if he knew Booth, he said he had been introduced to him at church in the fall before, but had no other acquaintance with him. Being asked if the man whose leg he had dressed was not Booth, he said he was not. When told by the officer that he would have to search the house, his wife went upstairs and brought down a boot that Mudd had removed from Booth's foot by ripping it down in front, and it was seen that on the inside of the boot leg, near the top, was written, "J. Wilkes," and also the maker's name. Mudd was interviewed two or three times before his arrest, and prevaricated every time so much that he frequently contradicted himself. It was noticed that he was never at home when called for, but was not far off, as he always made his appearance in a short time when sent for by his wife. He was finally placed under arrest; and upon the photograph of Booth being shown to him, and being asked if that looked like Booth, he said he thought not, but finally concluded there was some resemblance to Booth across the eyes. He was taken to Washington and held as a prisoner. Mudd was a physician, living on a farm. He had had a considerable number of slaves at the breaking out of the rebellion, most of whom had left him during the previous winter. His father also, living in the neighborhood, was a large land and slave holder, and Mudd's disloyalty was no doubt of the rabid type. His home was a place of resort for returned rebel soldiers and recruiting parties, and he had a place of concealment in the pines near his house, where they were sheltered and cared for, the doctor sending their food to them by his slaves; and if, at any time, any of these parties ventured to his house to take their meals, a slave was always placed on watch to give notice of the approach of any one.

The letter of introduction to Dr. Mudd which Booth had, as related by Arnold, had no doubt been presented in the fall, at the time Mudd admitted having been introduced to him at church; and from that time their intimacy commenced. This was in November, 1864.

About the 23d of December, 1864, Mudd visited Booth in Washington, and introduced him to John H. Surratt, under the following circumstances: Wiechmann and Surratt were on the street together, when Wiechmann heard some one call, "Surratt! Surratt!" and turning round, they were met by Dr. Mudd and Booth. Mudd introduced Booth to Surratt, and then Surratt introduced both of them to Wiechmann. They went, by invitation of Booth, to the National Hotel, where Booth had a room, and were served by him with wine and cigars. Mudd went out into a passage and called Booth. They remained out of the room for a short time, and conversed in a low tone of voice. Upon their return to the room Booth called Surratt, and the three went out again into the passage, and were engaged for some time in a private conference. Upon their return, Mudd made an explanation, by way of apology, to Wiechmann, saying that Booth wanted to buy his farm, but he did not care to sell. Booth also apologized, giving the same excuse. The three then took seats around a table, when Booth took an envelope from his pocket, and upon this, with his pencil, commenced drawing lines, as if marking roads. Whilst engaged in doing this the three were conversing in so low a tone that Wiechmann could not hear what was said.

Mudd made one or two other visits to Washington during the winter, and his business seemed always to be with Booth and Surratt. At least, he was always found in their company.

According to one of Mudd's various statements, Booth and Herold left his house between three and four o'clock in the afternoon. It will be noted that he at first denied their having been there at all. Then he admitted that two strangers had been there on Saturday morning; that he had dressed a broken leg for one of them, and had a crutch made for him, and they left after breakfast. That they remained until after Dana and his party passed down to Bryantown, there is no doubt; and that they left as soon as possible, assisted by Mudd, after the soldiers passed, as we have heretofore seen. Mudd, after his conviction and sentence, whilst being conveyed to the Dry Tortugas, admitted, voluntarily, to Captain Dutton that he knew Booth when he came to his house on the morning of the 15th of April; and also that he went to Washington in December by appointment with Booth, to introduce him to Surratt. He might just as well have admitted his complicity in the conspiracy. Mudd's expression of countenance was that of a hypocrite. He had the bump of secretiveness largely developed; and it would have taken months of favorable acquaintanceship to have removed the unfavorable impression made by the first scanning of the man. He had the appearance of a natural born liar and deceiver.

We have now Mrs. Mary E. Surratt, Edward Spangler, Lewis Payne, David E. Herold, Samuel Arnold, Michael O'Laughlin, George A. Atzerodt, and Dr. Samuel Mudd under arrest and held for trial by the government under the charge of being co-conspirators with John H. Surratt, Booth, and others yet to be named, and still others unknown and who never will be known. The evidence yet to be adduced makes it clear that there were quite a number of these conspirators in Washington at the time of the assassination who were never discovered, encouraging by their presence, and aiding and abetting, Booth and his associates.

There are good reasons for believing that the purpose of Booth and his fellow-conspirators was known to many, both in Canada and the United States, who were interested in the destruction of our government. It may yet happen that a sufficient amount of evidence may be found to justify this, or some other writer, in making explicit charges that are for the present withheld.

GEORGE E. ATZERODT.

In regard to the persons above named who were put upon their trial, the writer will only say that, in giving an account of the grounds of arrest in each case, he has stated the facts proven by unimpeached witnesses before the Commission, whose testimony governed the decisions of the court in their respective cases, and that his statements of the facts in evidence will be found to be fully vindicated by a critical examination and study of the testimony as given by Pittman in his official report of the trial. He feels sure that no one, with that report before him, can impeach the account he has given of the parts acted by each one of the prisoners named in this great tragedy; and upon these facts must rest the judgment of mankind, as did the judgment of the court.
