In answer to their resolution of the 11th instant [ultimo], "that the President of the United States furnish to the House, if not incompatible with the public service, the reasons that have induced him to assemble so large a number of troops in this city, and why they are kept here; and whether he has any information of a conspiracy upon the part of any portion of the citizens of this country to seize upon the capital and prevent the inauguration of the President elect," the President submits that the number of troops assembled in this city is not large, as the resolution presupposes, its total amount being 653 men exclusive of the marines, who are, of course, at the navy-yard as their appropriate station. These troops were ordered here to act as a _posse comitatus_, in strict subordination to the civil authority, for the purpose of preserving peace and order in the city of Washington should this be necessary before or at the period of the inauguration of the President elect. Since the date of the resolution Hon. Mr. Howard, from the select committee, has made a report to the House on this subject. It was thoroughly investigated by the committee, and although they have expressed the opinion that the evidence before them does not prove the existence of a secret organization here or elsewhere hostile to the Government that has for its object, upon its own responsibility, an attack upon the capital or any of the public property here, or an interruption of any of the functions of the Government, yet the House laid upon the table by a very large majority a resolution expressing the opinion "that the regular troops now in this city ought to be forthwith removed therefrom." This of itself was a sufficient reason for not withdrawing the troops.
