Since that time an envoy extraordinary and minister plenipotentiary has been accredited to this Government by that of the Mexican Republic.  He brought with him assurances of a sincere desire that the pending differences between the two Governments should be terminated in a manner satisfactory to both.  He was received with reciprocal assurances, and a hope was entertained that his mission would lead to a speedy, satisfactory, and final adjustment of all existing subjects of complaint.  A sincere believer in the wisdom of the pacific policy by which the United States have always been governed in their intercourse with foreign nations, it was my particular desire, from the proximity of the Mexican Republic and well-known occurrences on our frontier, to be instrumental in obviating all existing difficulties with that Government and in restoring to the intercourse between the two Republics that liberal and friendly character by which they should always be distinguished.  I regret, therefore, the more deeply to have found in the recent communications of that Government so little reason to hope that any future efforts of mine for the accomplishment of those desirable objects would be successful.

Although the larger number—­and many of them aggravated cases of personal wrongs—­have been now for years before the Mexican Government, and some of the causes of national complaint, and those of the most offensive character, admitted of immediate, simple, and satisfactory replies, it is only within a few days past that any specific communication in answer to our last demand, made five months ago, has been received from the Mexican minister.  By the report of the Secretary of State herewith presented and the accompanying documents it will be seen that for not one of our public complaints has satisfaction been given or offered, that but one of the cases of personal wrong has been favorably considered, and that but four cases of both descriptions out of all those formally presented and earnestly pressed have as yet been decided upon by the Mexican Government.

Not perceiving in what manner any of the powers given to the Executive alone could be further usefully employed in bringing this unfortunate controversy to a satisfactory termination, the subject was by my predecessor referred to Congress as one calling for its interposition.  In accordance with the clearly understood wishes of the Legislature, another and formal demand for satisfaction has been made upon the Mexican Government, with what success the documents now communicated will show.  On a careful and deliberate examination of their contents, and considering the spirit manifested by the Mexican Government, it has become my painful duty to return the subject as it now stands to Congress, to whom it belongs to decide upon the time, the mode, and the measure of redress.  Whatever may be your decision, it shall be faithfully executed, confident that it will be characterized by that moderation and justice which will, I trust, under all circumstances govern the councils of our country.
