It is gratifying, not only to those who consider the commercial interests of nations, but also to all who favor the progress of knowledge and the diffusion of religion, to see a community emerge from a savage state and attain such a degree of civilization in those distant seas.

It is much to be deplored that the internal tranquillity of the Mexican Republic should again be seriously disturbed, for since the peace between that Republic and the United States it had enjoyed such comparative repose that the most favorable anticipations for the future might with a degree of confidence have been indulged.  These, however, have been thwarted by the recent outbreak in the State of Tamaulipas, on the right bank of the Rio Bravo.  Having received information that persons from the United States had taken part in the insurrection, and apprehending that their example might be followed by others, I caused orders to be issued for the purpose of preventing any hostile expeditions against Mexico from being set on foot in violation of the laws of the United States.  I likewise issued a proclamation upon the subject, a copy of which is herewith laid before you.  This appeared to be rendered imperative by the obligations of treaties and the general duties of good neighborhood.

In my last annual message I informed Congress that citizens of the United States had undertaken the connection of the two oceans by means of a railroad across the Isthmus of Tehuantepec, under a grant of the Mexican Government to a citizen of that Republic, and that this enterprise would probably be prosecuted with energy whenever Mexico should consent to such stipulations with the Government of the United States as should impart a feeling of security to those who should invest their property in the enterprise.

A convention between the two Governments for the accomplishment of that end has been ratified by this Government, and only awaits the decision of the Congress and the Executive of that Republic.

Some unexpected difficulties and delays have arisen in the ratification of that convention by Mexico, but it is to be presumed that her decision will be governed by just and enlightened views, as well of the general importance of the object as of her own interests and obligations.

In negotiating upon this important subject this Government has had in view one, and only one, object.  That object has been, and is, the construction or attainment of a passage from ocean to ocean, the shortest and the best for travelers and merchandise, and equally open to all the world.  It has sought to obtain no territorial acquisition, nor any advantages peculiar to itself; and it would see with the greatest regret that Mexico should oppose any obstacle to the accomplishment of an enterprise which promises so much convenience to the whole commercial world and such eminent advantages to Mexico herself.  Impressed with these sentiments and these convictions, the Government will continue to exert all proper efforts to bring about the necessary arrangement with the Republic of Mexico for the speedy completion of the work.
