With the remaining powers of Europe, with those on the coast of Barbary, and with all the new South American States our relations are of a friendly character. We have ministers plenipotentiary residing with the Republics of Colombia and Chile, and have received ministers of the same rank from Colombia, Guatemala, Buenos Ayres, and Mexico. Our commercial relations with all those States are mutually beneficial and increasing. With the Republic of Colombia a treaty of commerce has been formed, of which a copy is received and the original daily expected. A negotiation for a like treaty would have been commenced with Buenos Ayres had it not been prevented by the indisposition and lamented decease of Mr. Rodney, our minister there, and to whose memory the most respectful attention has been shewn by the Government of that Republic. An advantageous alteration in our treaty with Tunis has been obtained by our consular agent residing there, the official document of which when received will be laid before the Senate. The attention of the Government has been drawn with great solicitude to other subjects, and particularly to that relating to a state of maritime war, involving the relative rights of neutral and belligerent in such wars. Most of the difficulties which we have experienced and of the losses which we have sustained since the establishment of our independence have proceeded from the unsettled state of those rights and the extent to which the belligerent claim has been carried against the neutral party. It is impossible to look back on the occurrences of the late wars in Europe, and to behold the disregard which was paid to our rights as a neutral power, and the waste which was made of our commerce by the parties to those wars by various acts of their respective Governments, and under the pretext by each that the other had set the example, without great mortification and a fixed purpose never to submit to the like in future. An attempt to remove those causes of possible variance by friendly negotiation and on just principles which should be applicable to all parties could, it was presumed, be viewed by none other than as a proof of an earnest desire to preserve those relations with every power. In the late war between France and Spain a crisis occurred in which it seemed probable that all the controvertible principles involved in such wars might be brought into discussion and settled to the satisfaction of all parties. Propositions having this object in view have been made to the Governments of Great Britain, France, Russia, and of other powers, which have been received in a friendly manner by all, but as yet no treaty has been formed with either for its accomplishment. The policy will, it is presumed, be persevered in, and in the hope that it may be successful.
