"That the following letters and packets and no others shall be received and conveyed by post, free of postage under such restrictions as are hereinafter provided, that is to say: all letters and packages to or from the President or Vice-President of the United States, and all letters and packages not exceeding 2 ounces in weight, to or from any member of the Senate or House of Representatives, the Secretary of the Senate, or Clerk of the House of Representatives, during their actual attendance in any session of Congress, and twenty days after such session, all letters to and from the Secretary of the Treasury and his assistant; Comptroller, Register and Auditor of the Treasury, Treasurer, Secretary of State, Secretary of War, the Committee for settling accounts between the United States and individual States, the Postmaster General and his assistant.
