I communicate herewith reports of the Secretary of War and the Secretary of the Treasury, with accompanying documents, in answer to a resolution of the Senate "requesting the President to inform the Senate whether any funds of the Government, and, if any, what amount, have been remitted from the Atlantic States to New Orleans or to the disbursing officers of the American Army in Mexico since the 1st of September last, and, if any remitted, in what funds remitted, whether in gold or silver coin, Treasury notes, bank notes, or bank checks, and, if in whole or in part remitted in gold and silver, what has been the expense to the Government of each of said remittances." JAMES K. POLK. WASHINGTON, _February 10, 1847_. _To the Senate of the United States_: I transmit to the Senate, for their advice with regard to its ratification, "a general treaty of peace, amity, navigation, and commerce between the United States of America and the Republic of New Granada," concluded at Bogota on the 12th December last by Benjamin A. Bidlack, chargé d'affaires of the United States, on their part, and by Manuel Maria Mallarino, secretary of state and foreign relations, on the part of that Republic. It will be perceived by the thirty-fifth article of this treaty that New Granada proposes to guarantee to the Government and citizens of the United States the right of passage across the Isthmus of Panama over the natural roads and over any canal or railroad which may be constructed to unite the two seas, on condition that the United States shall make a similar guaranty to New Granada of the neutrality of this portion of her territory and her sovereignty over the same. The reasons which caused the insertion of this important stipulation in the treaty will be fully made known to the Senate by the accompanying documents. From these it will appear that our chargé d'affaires acted in this particular upon his own responsibility and without instructions. Under such circumstances it became my duty to decide whether I would submit the treaty to the Senate, and after mature consideration I have determined to adopt this course. The importance of this concession to the commercial and political interests of the United States can not easily be overrated. The route by the Isthmus of Panama is the shortest between the two oceans, and from the information herewith communicated it would seem to be the most practicable for a railroad or canal. The vast advantages to our commerce which would result from such a communication, not only with the west coast of America, but with Asia and the islands of the Pacific, are too obvious to require any detail. Such a passage would relieve us from a long and dangerous navigation of more than 9,000 miles around Cape Horn and render our communication with our possessions on the northwest coast of America comparatively easy and speedy.
