The Government of Central America has expelled from its territory the party which some time since disturbed its peace. Desirous of fostering a favorable disposition toward us, which has on more than one occasion been evinced by this interesting country, I made a second attempt in this year to establish a diplomatic intercourse with them; but the death of the distinguished citizen whom I had appointed for that purpose has retarded the execution of measures from which I hoped much advantage to our commerce. The union of the three States which formed the Republic of Colombia has been dissolved, but they all, it is believed, consider themselves as separately bound by the treaty which was made in their federal capacity. The minister accredited to the federation continues in that character near the Government of New Grenada, and hopes were entertained that a new union would be formed between the separate States, at least for the purposes of foreign intercourse. Our minister has been instructed to use his good offices, when ever they shall be desired, to produce the reunion so much to be wished for, the domestic tranquillity of the parties, and the security and facility of foreign commerce. Some agitations naturally attendant on an infant reign have prevailed in the Empire of Brazil, which have had the usual effect upon commercial operations, and while they suspended the consideration of claims created on similar occasions, they have given rise to new complaints on the part of our citizens. A proper consideration for calamities and difficulties of this nature has made us less urgent and peremptory in our demands for justice than duty to our fellow citizens would under other circumstances have required. But their claims are not neglected, and will on all proper occasions be urged, and it is hoped with effect. I refrain from making any communication on the subject of our affairs with Buenos Ayres, because the negotiation communicated to you in my last annual message was at the date of our last advices still pending and in a state that would render a publication of the details inexpedient. A treaty of amity and commerce has been formed with the Republic of Chili, which, if approved by the Senate, will be laid before you. That Government seems to be established, and at peace with its neighbors; and its ports being the resorts of our ships which are employed in the highly important trade of the fisheries, this commercial convention can not but be of great advantage to our fellow citizens engaged in that perilous but profitable business.
