Without this the President may be placed in a painful position before the meeting of the next Congress. In the present disturbed condition of Mexico and one or more of the other Republics south of us, no person can foresee what occurrences may take place before that period. In case of emergency, our citizens, seeing that they do not enjoy the same protection with subjects of European Governments, will have just cause to complain. On the other hand, should the Executive interpose, and especially should the result prove disastrous and valuable lives be lost, he might subject himself to severe censure for having assumed a power not confided to him by the Constitution. It is to guard against this contingency that I now appeal to Congress. Having thus recommended to Congress a measure which I deem necessary and expedient for the interest and honor of the country, I leave the whole subject to their wisdom and discretion. JAMES BUCHANAN. WASHINGTON, _February 18, 1859_. _To the Senate of the United States_: I transmit to the Senate, for its consideration with a view to ratification, two conventions between the United States and China, one providing for the adjustment of claims of citizens of the United States on the Government of that Empire, the other for the regulation of trade, both signed at Shanghai on the 8th of November last. A copy of the dispatches of Mr. Reed to the Department of State on the subject is also herewith transmitted. JAMES BUCHANAN. WASHINGTON CITY, _February 25, 1859_. _To the House of Representatives_: I transmit herewith a report from the Secretary of the Navy, with the accompanying documents, in obedience to the resolution of the House of Representatives adopted on the 28th of January, requesting the President of the United States "to communicate to this House a copy of all instructions given to the commanders of our African squadron since the ratification of the treaty of 1842, called the Washington treaty, with a copy or statement of whatever regulations were entered into by the commanders of the two squadrons for more fully accomplishing the object of the eighth article of said treaty," etc. JAMES BUCHANAN. WASHINGTON, _February 26, 1859_. _To the Senate of the United States_: In answer to the resolution of the Senate of the 23d instant, requesting a copy of certain letters of Horatio J. Perry, late secretary to the legation of the United States at Madrid, I transmit a report from the Secretary of State, with the documents which accompanied it. JAMES BUCHANAN. WASHINGTON CITY, _March 1, 1859_. _To the Senate of the United States_: I transmit herewith a report from the Secretary of War, with accompanying paper, in obedience to the resolution of the Senate adopted 23d February, requesting the President of the United States "to communicate to the Senate a copy of the opinion of Judge Brewer in the Great Falls land condemnation case, involving a claim for damages to be paid by the United States."
