agreements, and arrangements which have been made and of proposals which
have been received for heating and ventilating the Capitol extension,
the Post-Office, and other public buildings in course of construction
under the management of Captain Meigs, and of the action of the
Secretary of War and Captain Meigs thereon," I transmit herewith all
the papers called for by the resolution.
