I regret to be obliged to inform you that no convention for the settlement of the claims of our citizens upon Mexico has yet been ratified by the Government of that country. The first convention formed for that purpose was not presented by the President of Mexico for the approbation of its Congress, from a belief that the King of Prussia, the arbitrator in case of disagreement in the joint commission to be appointed by the United States and Mexico, would not consent to take upon himself that friendly office. Although not entirely satisfied with the course pursued by Mexico, I felt no hesitation in receiving in the most conciliatory spirit the explanation offered, and also cheerfully consented to a new convention, in order to arrange the payments proposed to be made to our citizens in a manner which, while equally just to them, was deemed less onerous and inconvenient to the Mexican Government. Relying confidently upon the intentions of that Government, Mr. Ellis was directed to repair to Mexico, and diplomatic intercourse has been resumed between the two countries. The new convention has, he informs us, been recently submitted by the President of that Republic to its Congress under circumstances which promise a speedy ratification, a result which I can not allow myself to doubt. Instructions have been given to the commissioner of the United States under our convention with Texas for the demarcation of the line which separates us from that Republic. The commissioners of both Governments met in New Orleans in August last. The joint commission was organized, and adjourned to convene at the same place on the 12th of October. It is presumed to be now in the performance of its duties. The new Government of Texas has shown its desire to cultivate friendly relations with us by a prompt reparation for injuries complained of in the cases of two vessels of the United States. With Central America a convention has been concluded for the renewal of its former treaty with the United States. This was not ratified before the departure of our late charge d'affaires from that country, and the copy of it brought by him was not received before the adjournment of the Senate at the last session. In the meanwhile, the period limited for the exchange of ratifications having expired, I deemed it expedient, in consequence of the death of the charge d'affaires, to send a special agent to Central America to close the affairs of our mission there and to arrange with the Government an extension of the time for the exchange of ratifications.
