John Merryman, esq., of Baltimore county, President of the Maryland Agricultural Society, was arrested on Friday of last week, by order of the Government, and taken to Fort McHenry to await an investigation on a charge of Treason. On the petition of the prisoner, Roger B. Taney, Chief Justice of the Supreme Court, on Sunday issued a writ of habeas corpus, which was served on Gen. George Cadwallader directing him to produce the body of Merryman in Court by 11 o’clock, Monday.  

At the appointed hour Colonel Lee appeared in Court and slated that lie was instructed by General Cadwallader to express his regret that pressing duties in connection with his command prevented his appearing before his Honor in person, and to present his response to the writ. General Cadwallader in his reply states that Merryman was not arrested with his knowledge or by his order or direction, but by Col. Yohe acting under order of Major Keim,“ and is charged with various acts of treason, and with being publicly associated with and holding a commission as Lieutenant in a company having in their possession arms belonging to the United Slates, and avowing his purpose of aimed hostility against the Government.
