Congress having provided for a full mission to the States of Central America, a minister was sent thither in July last. As yet he has had time to visit only one of these States (Nicaragua), where he was received in the most friendly manner. It is hoped that his presence and good offices will have a benign effect in composing the dissensions which prevail among them, and in establishing still more intimate and friendly relations between them respectively and between each of them and the United States.
Considering the vast regions of this continent and the number of states which would be made accessible by the free navigation of the river Amazon, particular attention has been given to this subject. Brazil, through whose territories it passes into the ocean, has hitherto persisted in a policy so restricted in regard to the use of this river as to obstruct and nearly exclude foreign commercial intercourse with the States which lie upon its tributaries and upper branches. Our minister to that country is instructed to obtain a relaxation of that policy and to use his efforts to induce the Brazilian Government to open to common use, under proper safeguards, this great natural highway for international trade. Several of the South American States are deeply interested in this attempt to secure the free navigation of the Amazon, and it is reasonable to expect their cooperation in the measure. As the advantages of free commercial intercourse among nations are better understood, more liberal views are generally entertained as to the common rights of all to the free use of those means which nature has provided for international communication. To these more liberal and enlightened views it is hoped that Brazil will conform her policy and remove all unnecessary restrictions upon the free use of a river which traverses so many states and so large a part of the continent. I am happy to inform you that the Republic of Paraguay and the Argentine Confederation have yielded to the liberal policy still resisted by Brazil in regard to the navigable rivers within their respective territories. Treaties embracing this subject, among others, have been negotiated with these Governments, which will be submitted to the Senate at the present session.
