On the other hand, should the constitutional party prevail and their authority be established over the Republic, there is reason to hope that they will be animated by a less unfriendly spirit and may grant that redress to American citizens which justice requires so far as they may possess the means. But for this expectation I should at once have recommended to Congress to grant the necessary power to the President to take possession of a sufficient portion of the remote and unsettled territory of Mexico, to be held in pledge until our injuries shall be redressed and our just demands be satisfied. We have already exhausted every milder means of obtaining justice. In such a case this remedy of reprisals is recognized by the law of nations, not only as just in itself, but as a means of preventing actual war.

But there is another view of our relations with Mexico, arising from the unhappy condition of affairs along our southwestern frontier, which demands immediate action. In that remote region, where there are but few white inhabitants, large bands of hostile and predatory Indians roam promiscuously over the Mexican States of Chihuahua and Sonora and our adjoining Territories. The local governments of these States are perfectly helpless and are kept in a state of constant alarm by the Indians. They have not the power, if they possessed the will, even to restrain lawless Mexicans from passing the border and committing depredations on our remote settlers. A state of anarchy and violence prevails throughout that distant frontier. The laws are a dead letter and life and property wholly insecure. For this reason the settlement of Arizona is arrested, whilst it is of great importance that a chain of inhabitants should extend all along its southern border sufficient for their own protection and that of the United States mail passing to and from California. Well-founded apprehensions are now entertained that the Indians and wandering Mexicans, equally lawless, may break up the important stage and postal communication recently established between our Atlantic and Pacific possessions. This passes very near to the Mexican boundary throughout the whole length of Arizona. I can imagine no possible remedy for these evils and no mode of restoring law and order on that remote and unsettled frontier but for the Government of the United States to assume a temporary protectorate over the northern portions of Chihuahua and Sonora and to establish military posts within the same; and this I earnestly recommend to Congress. This protection may be withdrawn as soon as local governments shall be established in these Mexican States capable of performing their duties to the United States, restraining the lawless, and preserving peace along the border.

I do not doubt that this measure will be viewed in a friendly spirit by the governments and people of Chihuahua and Sonora, as it will prove equally effectual for the protection of their citizens on that remote and lawless frontier as for citizens of the United States.

And in this connection permit me to recall your attention to the condition of Arizona. The population of that Territory, numbering, as is alleged, more than 10,000 souls, are practically without a government, without laws, and without any regular administration of justice. Murder and other crimes are committed with impunity. This state of things calls loudly for redress, and I therefore repeat my recommendation for the establishment of a Territorial government over Arizona.

The political condition of the narrow isthmus of Central America, through which transit routes pass between the Atlantic and Pacific oceans, presents a subject of deep interest to all commercial nations. It is over these transits that a large proportion of the trade and travel between the European and Asiatic continents is destined to pass. To the United States these routes are of incalculable importance as a means of communication between their Atlantic and Pacific possessions. The latter now extend throughout seventeen degrees of latitude on the Pacific coast, embracing the important State of California and the flourishing Territories of Oregon and Washington. All commercial nations therefore have a deep and direct interest that these communications shall be rendered secure from interruption. If an arm of the sea connecting the two oceans penetrated through Nicaragua and Costa Rica, it could not be pretended that these States would have the right to arrest or retard its navigation to the injury of other nations. The transit by land over this narrow isthmus occupies nearly the same position. It is a highway in which they themselves have little interest when compared with the vast interests of the rest of the world. Whilst their rights of sovereignty ought to be respected, it is the duty of other nations to require that this important passage shall not be interrupted by the civil wars and revolutionary outbreaks which have so frequently occurred in that region. The stake is too important to be left at the mercy of rival companies claiming to hold conflicting contracts with Nicaragua. The commerce of other nations is not to stand still and await the adjustment of such petty controversies. The Government of the United States expect no more than this, and they will not be satisfied with less. They would not, if they could, derive any advantage from the Nicaragua transit not common to the rest of the world. Its neutrality and protection for the common use of all nations is their only object. They have no objection that Nicaragua shall demand and receive a fair compensation from the companies and individuals who may traverse the route, but they insist that it shall never hereafter be closed by an arbitrary decree of that Government. If disputes arise between it and those with whom they may have entered into contracts, these must be adjusted by some fair tribunal provided for the purpose, and the route must not be closed pending the controversy. This is our whole policy, and it can not fail to be acceptable to other nations.

All these difficulties might be avoided if, consistently with the good faith of Nicaragua, the use of this transit could be thrown open to general competition, providing at the same time for the payment of a reasonable rate to the Nicaraguan Government on passengers and freight.

In August, 1852, the Accessory Transit Company made its first inter-oceanic trip over the Nicaraguan route, and continued in successful operation, with great advantage to the public, until the 18th February, 1856, when it was closed and the grant to this company as well as its charter were summarily and arbitrarily revoked by the Government of President Rivas. Previous to this date, however, in 1854, serious disputes concerning the settlement of their accounts had arisen between the company and the Government, threatening the interruption of the route at any moment. These the United States in vain endeavored to compose. It would be useless to narrate the various proceedings which took place between the parties up till the time when the transit was discontinued. Suffice it to say that since February, 1856, it has remained closed, greatly to the prejudice of citizens of the United States. Since that time the competition has ceased between the rival routes of Panama and Nicaragua, and in consequence thereof an unjust and unreasonable amount has been exacted from our citizens for their passage to and from California. A treaty was signed on the 16th day of November, 1857, by the Secretary of State and minister of Nicaragua, under the stipulations of which the use and protection of the transit route would have been secured, not only to the United States, but equally to all other nations. How and on what pretext this treaty has failed to receive the ratification of the Nicaraguan Government will appear by the papers herewith communicated from the State Department. The principal objection seems to have been to the provision authorizing the United States to employ force to keep the route open in case Nicaragua should fail to perform her duty in this respect. From the feebleness of that Republic, its frequent changes of government, and its constant internal dissensions, this had become a most important stipulation, and one essentially necessary, not only for the security of the route, but for the safety of American citizens passing and repassing to and from our Pacific possessions. Were such a stipulation embraced in a treaty between the United States and Nicaragua, the knowledge of this fact would of itself most probably prevent hostile parties from committing aggressions on the route, and render our actual interference for its protection unnecessary.

The executive government of this country in its intercourse with foreign nations is limited to the employment of diplomacy alone. When this fails it can proceed no further. It can not legitimately resort to force without the direct authority of Congress, except in resisting and repelling hostile attacks. It would have no authority to enter the territories of Nicaragua even to prevent the destruction of the transit and protect the lives and property of our own citizens on their passage. It is true that on a sudden emergency of this character the President would direct any armed force in the vicinity to march to their relief, but in doing this he would act upon his own responsibility.

Under these circumstances I earnestly recommend to Congress the passage of an act authorizing the President, under such restrictions as they may deem proper, to employ the land and naval forces of the United States in preventing the transit from being obstructed or closed by lawless violence, and in protecting the lives and property of American citizens traveling thereupon, requiring at the same time that these forces shall be withdrawn the moment the danger shall have passed away. Without such a provision our citizens will be constantly exposed to interruption in their progress and to lawless violence.

A similar necessity exists for the passage of such an act for the protection of the Panama and Tehuantepec routes.
