Deeply interested as we are in the prosperity of our sister Republics, and more particularly in that of our immediate neighbor, it would be most gratifying to me were I permitted to say that the treatment which we have received at her hands has been as universally friendly as the early and constant solicitude manifested by the United States for her success gave us a right to expect. But it becomes my duty to inform you that prejudices long indulged by a portion of the inhabitants of Mexico against the envoy extraordinary and minister plenipotentiary of the United States have had an unfortunate influence upon the affairs of the two countries, and have diminished that usefulness to his own which was justly to be expected from his talents and zeal. To this cause, in a great degree, is to be imputed the failure of several measures equally interesting to both parties, but particularly that of the Mexican Government to ratify a treaty negotiated and concluded in its own capital and under its own eye. Under these circumstances it appeared expedient to give to Mr. Poinsett the option either to return or not, as in his judgment the interest of his country might require, and instructions to that end were prepared; but before they could be dispatched a communication was received from the Government of Mexico, through its charge d'affaires here, requesting the recall of our minister. This was promptly complied with, and a representative of a rank corresponding with that of the Mexican diplomatic agent near this Government was appointed. Our conduct toward that Republic has been uniformly of the most friendly character, and having thus removed the only alleged obstacle to harmonious intercourse, I can not but hope that an advantageous change will occur in our affairs. In justice to Mr. Poinsett it is proper to say that my immediate compliance with the application for his recall and the appointment of a successor are not to be ascribed to any evidence that the imputation of an improper interference by him in the local politics of Mexico was well founded, nor to a want of confidence in his talents or integrity, and to add that the truth of the charges has never been affirmed by the federal Government of Mexico in its communications with us. I consider it one of the most urgent of my duties to bring to your attention the propriety of amending that part of the Constitution which relates to the election of President and Vice-President. Our system of government was by its framers deemed an experiment, and they therefore consistently provided a mode of remedying its defects.
