I transmit herewith a report of the Secretary of State, with accompanying documents, in compliance with the resolution of the Senate of the 17th instant, requesting the President to communicate to that body "copies of the correspondence between the minister of the United States at London and any authorities of the British Government in relation to a postal arrangement between the two countries." JAMES K. POLK. MARCH 27, 1848. WASHINGTON, _April 3, 1848_. _To the Senate and House of Representatives of the United States_: I communicate to Congress, for their information, a copy of a dispatch, with the accompanying documents, received at the Department of State from the envoy extraordinary and minister plenipotentiary of the United States at Paris, giving official information of the overthrow of the French Monarchy, and the establishment in its stead of a "provisional government based on republican principles." This great event occurred suddenly, and was accomplished almost without bloodshed. The world has seldom witnessed a more interesting or sublime spectacle than the peaceful rising of the French people, resolved to secure for themselves enlarged liberty, and to assert, in the majesty of their strength, the great truth that in this enlightened age man is capable of governing himself. The prompt recognition of the new Government by the representative of the United States at the French Court meets my full and unqualified approbation, and he has been authorized in a suitable manner to make known this fact to the constituted authorities of the French Republic. Called upon to act upon a sudden emergency, which could not have been anticipated by his instructions, he judged rightly of the feelings and sentiments of his Government and of his countrymen, when, in advance of the diplomatic representatives of other countries, he was the first to recognize, so far as it was in his power, the free Government established by the French people. The policy of the United States has ever been that of nonintervention in the domestic affairs of other countries, leaving to each to establish the form of government of its own choice. While this wise policy will be maintained toward France, now suddenly transformed from a monarchy into a republic, all our sympathies are naturally enlisted on the side of a great people who, imitating our example, have resolved to be free. That such sympathy should exist on the part of the people of the United States with the friends of free government in every part of the world, and especially in France, is not remarkable. We can never forget that France was our early friend in our eventful Revolution, and generously aided us in shaking off a foreign yoke and becoming a free and independent people.
