Copies of the treaties concluded with the Governments of Siam and Muscat are transmitted for the information of Congress, the ratifications having been received and the treaties made public since the close of the last annual session.  Already have we reason to congratulate ourselves on the prospect of considerable commercial benefit; and we have, besides, received from the Sultan of Muscat prompt evidence of his desire to cultivate the most friendly feelings, by liberal acts toward one of our vessels, bestowed in a manner so striking as to require on our part a grateful acknowledgment.

Our commerce with the islands of Cuba and Porto Rico still labors under heavy restrictions, the continuance of which is a subject of regret.  The only effect of an adherence to them will be to benefit the navigation of other countries at the expense of both the United States and Spain.

The independent nations of this continent have ever since they emerged from the colonial state experienced severe trials in their progress to the permanent establishment of liberal political institutions.  Their unsettled condition not only interrupts their own advances to prosperity, but has often seriously injured the other powers of the world.  The claims of our citizens upon Peru, Chili, Brazil, the Argentine Republic, the Governments formed out of the Republics of Colombia and Mexico, are still pending, although many of them have been presented for examination more than twenty years.  New Granada, Venezuela, and Ecuador have recently formed a convention for the purpose of ascertaining and adjusting claims upon the Republic of Colombia, from which it is earnestly hoped our citizens will ere long receive full compensation for the injuries inflicted upon them and for the delay in affording it.

An advantageous treaty of commerce has been concluded by the United States with the Peru-Bolivian Confederation, which wants only the ratification of that Government.  The progress of a subsequent negotiation for the settlement of claims upon Peru has been unfavorably affected by the war between that power and Chili and the Argentine Republic, and the same event is also likely to produce delays in the settlement of out demands on those powers.

The aggravating circumstances connected with our claims upon Mexico and a variety of events touching the honor and integrity of our Government led my predecessor to make at the second session of the last Congress a special recommendation of the course to be pursued to obtain a speedy and final satisfaction of the injuries complained of by this Government and by our citizens.  He recommended a final demand of redress, with a contingent authority to the Executive to make reprisals if that demand should be made in vain.  From the proceedings of Congress on that recommendation it appeared that the opinion of both branches of the Legislature coincided with that of the Executive, that any mode of redress known to the law of nations might justifiably be used.  It was obvious, too, that Congress believed with the President that another demand should be made, in order to give undeniable and satisfactory proof of our desire to avoid extremities with a neighboring power, but that there was an indisposition to vest a discretionary authority in the Executive to take redress should it unfortunately be either denied or unreasonably delayed by the Mexican Government.
