I am directed by the President to inform you that, as the time prescribed for your return to the United States with the result of your negotiation with the Mexican Government has elapsed, he has determined upon the immediate appointment of a successor. A nomination will accordingly be made to the Senate to-morrow.

I have also to acquaint you that Mr. Castillo having recently called on me to request, by direction of the Mexican Government, that you should be recalled, but in a manner the least disagreeable to your feelings, he was apprized that your mission would terminate at the commencement of the present month; and as he expressed his opinion that this measure would be satisfactory to his Government, the application for your recall was not formally made.
