I have thought it my duty to communicate this occurrence to Congress, to whose wisdom it belongs to consider whether it is of a nature requiring from them any animadversion, and also whether any further laws or regulations are necessary to insure security in the official intercourse between the President and Congress, and to prevent disorders within the Capitol itself. In the deliberations of Congress upon this subject it is neither expected nor desired that any consequence shall be attached to the private relation in which my secretary stands to me. John Quincy Adams. Washington, _April 21, 1828_. _To the Senate of the United States_: I transmit to the Senate, for their consideration and advice, a treaty of limits between the United States of America and the United Mexican States, concluded by the plenipotentiaries of the two Governments on the 12th of January last. A copy of the treaty and the protocols of conference between the plenipotentiaries during the negotiation are inclosed with it. John Quincy Adams. Washington, _April 22,1828_. _To the House of Representatives of the United States_: A copy of the opinion of the Attorney-General, dated 17th May, 1826, upon the construction of the award of the Emperor of Russia under the treaty of Ghent and upon certain questions propounded to him in relation thereto, subjoined to a report from the Secretary of State, are herewith communicated to the House, in compliance with their resolution of the 17th instant. John Quincy Adams. Washington, _April 24, 1828_. _To the Senate of the United States_: I transmit to the Senate, for the exercise of their constitutional authority thereon, a treaty of amity, commerce, and navigation between the United States of America and the United Mexican States, signed by their respective plenipotentiaries on the 14th of February last, with a copy of the treaty and the protocols of conference during and subsequent to the negotiation. John Quincy Adams. Washington, _April 28,1828_. _To the House of Representatives of the United States_: In compliance with a resolution of the House of Representatives of the 9th instant, requesting a communication of the correspondence between this Government and that of Great Britain on the subject of the trade between the United States and the British colonial possessions in the West Indies and North America, not heretofore communicated, I transmit to the House a report from the Secretary of State, with the correspondence desired. John Quincy Adams. Washington, _April 30, 1828_. _To the Senate and House of Representatives of the United States_:
