I have presented thus fully to your view our commercial relations with other powers, that, seeing them in detail with each power, and knowing the basis on which they rest, Congress may in its wisdom decide whether any change ought to be made, and, if any, in what respect. If this basis is unjust or unreasonable, surely it ought to be abandoned; but if it be just and reasonable, and any change in it will make concessions subversive of equality and tending in its consequences to sap the foundations of our prosperity, then the reasons are equally strong for adhering to the ground already taken, and supporting it by such further regulations as may appear to be proper, should any additional support be found necessary. The question concerning the construction of the first article of the treaty of Ghent has been, by a joint act of the representatives of the United States and of Great Britain at the Court of St. Petersburg, submitted to the decision of His Imperial Majesty the Emperor of Russia. The result of that submission has not yet been received. The commissioners under the 5th article of that treaty not having been able to agree upon their decision, their reports to the two Governments, according to the provisions of the treaty, may be expected at an early day. With Spain the treaty of February 22nd, 1819, has been partly carried into execution. Possession of East and West Florida has been given to the United States, but the officers charged with that service by an order from His Catholic Majesty, delivered by his minister to the Secretary of State, and transmitted by a special agent to the Captain-General of Cuba, to whom it was directed and in whom the Government of those Provinces was vested, have not only omitted, in contravention of the order of their Sovereign, the performance of the express stipulation to deliver over the archives and documents relating to the property and sovereignty of those Provinces, all of which it was expected would have been delivered either before or when the troops were withdrawn, but defeated since every effort of the United States to obtain them, especially those of the greatest importance. This omission has given rise to several incidents of a painful nature, the character of which will be fully disclosed by the documents which will be hereafter communicated.
