A treaty for the protection of trade-marks has been negotiated with Great Britain, which has been submitted to the Senate for its consideration. The revolution which recently occurred in Mexico was followed by the accession of the successful party to power and the installation of its chief, General Porfirio Diaz, in the Presidential office. It has been the custom of the United States, when such changes of government have heretofore occurred in Mexico, to recognize and enter into official relations with the de facto government as soon as it should appear to have the approval of the Mexican people and should manifest a disposition to adhere to the obligations of treaties and international friendship. In the present case such official recognition has been deferred by the occurrences on the Rio Grande border, the records of which have been already communicated to each House of Congress in answer to their respective resolutions of inquiry. Assurances have been received that the authorities at the seat of the Mexican Government have both the disposition and the power to prevent and punish such unlawful invasions and depredations. It is earnestly to be hoped that events may prove these assurances to be well rounded. The best interests of both countries require the maintenance of peace upon the border and the development of commerce between the two Republics. It is gratifying to add that this temporary interruption of official relations has not prevented due attention by the representatives of the United States in Mexico to the protection of American citizens, so far as practicable; nor has it interfered with the prompt payment of the amounts due from Mexico to the United States under the treaty of July 4, 1868, and the awards of the joint commission. While I do not anticipate an interruption of friendly relations with Mexico, yet I can not but look with some solicitude upon a continuance of border disorders as exposing the two countries to initiations of popular feeling and mischances of action which are naturally unfavorable to complete amity. Firmly determined that nothing shall be wanting on my part to promote a good understanding between the two nations, I yet must ask the attention of Congress to the actual occurrences on the border, that the lives and property of our citizens may be adequately protected and peace preserved.
