in which the claimants themselves have acquiesced.  The Governments of Denmark and of Naples have been recently reminded of those yet existing against them, nor will any of them be forgotten while a hope may be indulged of obtaining justice by the means within the constitutional power of the Executive, and without resorting to those means of self-redress which, as well as the time, circumstances, and occasion which may require them, are within the exclusive competency of the Legislature.

It is with great satisfaction that I am enabled to bear witness to the liberal spirit with which the Republic of Colombia has made satisfaction for well-established claims of a similar character, and among the documents now communicated to Congress will be distinguished a treaty of commerce and navigation with that Republic, the ratifications of which have been exchanged since the last recess of the Legislature.  The negotiation of similar treaties with all the independent South American States has been contemplated and may yet be accomplished.  The basis of them all, as proposed by the United States, has been laid in two principles—­the one of entire and unqualified reciprocity, the other the mutual obligation of the parties to place each other permanently upon the footing of the most favored nation.  These principles are, indeed, indispensable to the effectual emancipation of the American hemisphere from the thraldom of colonizing monopolies and exclusions, an event rapidly realizing in the progress of human affairs, and which the resistance still opposed in certain parts of Europe to the acknowledgment of the Southern American Republics as independent States will, it is believed, contribute more effectually to accomplish.  The time has been, and that not remote, when some of those States might, in their anxious desire to obtain a nominal recognition, have accepted of a nominal independence, clogged with burdensome conditions, and exclusive commercial privileges granted to the nation from which they have separated to the disadvantage of all others.  They are all now aware that such concessions to any European nation would be incompatible with that independence which they have declared and maintained.

Among the measures which have been suggested to them by the new relations with one another, resulting from the recent changes in their condition, is that of assembling at the Isthmus of Panama a congress, at which each of them should be represented, to deliberate upon objects important to the welfare of all.  The Republics of Colombia, of Mexico, and of Central America have already deputed plenipotentiaries to such a meeting, and they have invited the United States to be also represented there by their ministers.  The invitation has been accepted, and ministers on the part of the United States will be commissioned to attend at those deliberations, and to take part in them so far as may be compatible with that neutrality from which it is neither our intention nor the desire of the other American States that we should depart.
