With the Republic of Mexico it is our true policy to cultivate the most friendly relations. Since the ratification of the treaty of Guadalupe Hidalgo nothing has occurred of a serious character to disturb them. A faithful observance of the treaty and a sincere respect for her rights can not fail to secure the lasting confidence and friendship of that Republic. The message of my predecessor to the House of Representatives of the 8th of February last, communicating, in compliance with a resolution of that body, a copy of a paper called a protocol, signed at Queretaro on the 30th of May, 1848, by the commissioners of the United States and the minister of foreign affairs of the Mexican Government, having been a subject of correspondence between the Department of State and the envoy extraordinary and minister plenipotentiary of that Republic accredited to this Government, a transcript of that correspondence is herewith submitted.
The commissioner on the part of the United States for marking the boundary between the two Republics, though delayed in reaching San Diego by unforeseen obstacles, arrived at that place within a short period after the time required by the treaty, and was there joined by the commissioner on the part of Mexico. They entered upon their duties, and at the date of the latest intelligence from that quarter some progress had been made in the survey. The expenses incident to the organization of the commission and to its conveyance to the point where its operations were to begin have so much reduced the fund appropriated by Congress that a further sum, to cover the charges which must be incurred during the present fiscal year, will be necessary. The great length of frontier along which the boundary extends, the nature of the adjacent territory, and the difficulty of obtaining supplies except at or near the extremes of the line render it also indispensable that a liberal provision should be made to meet the necessary charges during the fiscal year ending on the 30th of June, 1851. I accordingly recommend this subject to your attention.
In the adjustment of the claims of American citizens on Mexico, provided for by the late treaty, the employment of counsel on the part of the Government may become important for the purpose of assisting the commissioners in protecting the interests of the United States. I recommend this subject to the early and favorable consideration of Congress.
Complaints have been made in regard to the inefficiency of the means provided by the Government of New Granada for transporting the United States mail across the Isthmus of Panama, pursuant to our postal convention with that Republic of the 6th of March, 1844. Our charge d'affaires at Bogota has been directed to make such representations to the Government of New Granada as will, it is hoped, lead to a prompt removal of this cause of complaint.
The sanguinary civil war with which the Republic of Venezuela has for some time past been ravaged has been brought to a close. In its progress the rights of some of our citizens resident or trading there have been violated. The restoration of order will afford the Venezuelan Government an opportunity to examine and redress these grievances and others of longer standing which our representatives at Caracas have hitherto ineffectually urged upon the attention of that Government.
The extension of the coast of the United States on the Pacific and the unexampled rapidity with which the inhabitants of California especially are increasing in numbers have imparted new consequence to our relations with the other countries whose territories border upon that ocean. It is probable that the intercourse between those countries and our possessions in that quarter, particularly with the Republic of Chili, will become extensive and mutually advantageous in proportion as California and Oregon shall increase in population and wealth. It is desirable, therefore, that this Government should do everything in its power to foster and strengthen its relations with those States, and that the spirit of amity between us should be mutual and cordial.
I recommend the observance of the same course toward all other American States. The United States stand as the great American power, to which, as their natural ally and friend, they will always be disposed first to look for mediation and assistance in the event of any collision between them and any European nation. As such we may often kindly mediate in their behalf without entangling ourselves in foreign wars or unnecessary controversies. Whenever the faith of our treaties with any of them shall require our interference, we must necessarily interpose.
A convention has been negotiated with Brazil providing for the satisfaction of American claims on that Government, and it will be submitted to the Senate. Since the last session of Congress we have received an envoy extraordinary and minister plenipotentiary from that Empire, and our relations with it are rounded upon the most amicable understanding.
