There may be reason to apprehend that the ratification of the “additional and secret article” might unreasonably delay and embarrass the final action on the treaty by Mexico.  I therefore submit whether that article should not be rejected by the Senate.

If the treaty shall be ratified as proposed to be amended, the cessions of territory made by it to the United States as indemnity, the provision for the satisfaction of the claims of our injured citizens, and the permanent establishment of the boundary of one of the States of the Union are objects gained of great national importance, while the magnanimous forbearance exhibited toward Mexico, it is hoped, may insure a lasting peace and good neighborhood between the two countries.

I communicate herewith a copy of the instructions given to Mr. Slidell in November, 1845, as envoy extraordinary and minister plenipotentiary to Mexico; a copy of the instructions given to Mr. Trist in April last, and such of the correspondence of the latter with the Department of State, not heretofore communicated to Congress, as will enable the Senate to understand the action which has been had with a view to the adjustment of our difficulties with Mexico.

To the Senate of the United States: 

In answer to the resolution of the Senate of the 24th instant, requesting to be informed whether the active operations of the Army of the United States in Mexico have been, and now are, suspended, and, if so, by whose agency and in virtue of what authority such armistice has been effected, I have to state that I have received no information relating to the subject other than that communicated to the Senate with my executive message of the 22d instant.

JAMES K. POLK.

WASHINGTON, February 29, 1848.

To the Senate of the United States: 

In compliance with the resolution of the Senate passed in “executive session” on yesterday, requesting the President “to communicate to the Senate, in confidence, the entire correspondence between Mr. Trist and the Mexican commissioners from the time of his arrival in Mexico until the time of the negotiation of the treaty submitted to the Senate; and also the entire correspondence between Mr. Trist and the Secretary of State in relation to his negotiations with the Mexican commissioners; also all the correspondence between General Scott and the Government and between General Scott and Mr. Trist since the arrival of Mr. Trist in Mexico which may be in the possession of the Government,” I transmit herewith the correspondence called for.  These documents are very voluminous, and presuming that the Senate desired them in reference to early action on the treaty with Mexico submitted to the consideration of that body by my message of the 22d instant, the originals of several of the letters of Mr. Trist are herewith, communicated, in order to save the time which would necessarily be required to make copies of them.  These original letters, it is requested, may be returned when the Senate shall have no further use for them.
