The question depending between the United States and Great Britain respecting the construction of the first article of the treaty of Ghent has been referred by both Governments to the decision of the Emperor of Russia, who has accepted the umpirage.

An attempt has been made with the Government of France to regulate by treaty the commerce between the two countries on the principle of reciprocity and equality.  By the last communication from the minister plenipotentiary of the United States at Paris, to whom full power had been given, we learn that the negotiation has been commenced there; but serious difficulties having occurred, the French Government had resolved to transfer it to the United States, for which purpose the minister plenipotentiary of France had been ordered to repair to this city, and whose arrival might soon be expected.  It is hoped that this important interest may be arranged on just conditions and in a manner equally satisfactory to both parties.  It is submitted to Congress to decide, until such arrangement is made, how far it may be proper, on the principle of the act of the last session which augmented the tonnage duty on French vessels, to adopt other measures for carrying more completely into effect the policy of that act.

The act referred to, which imposed new tonnage on French vessels, having been in force from and after the first day of July, it has happened that several vessels of that nation which had been dispatched from France before its existence was known have entered the ports of the United States, and been subject to its operation, without that previous notice which the general spirit of our laws gives to individuals in similar cases.  The object of that law having been merely to countervail the inequalities which existed to the disadvantage of the United States in their commercial intercourse with France, it is submitted also to the consideration of Congress whether, in the spirit of amity and conciliation which it is no less the inclination than the policy of the United States to preserve in their intercourse with other powers, it may not be proper to extend relief to the individuals interested in those cases by exempting from the operation of the law all those vessels which have entered our ports without having had the means of previously knowing the existence of the additional duty.

The contest between Spain and the colonies, according to the most authentic information, is maintained by the latter with improved success.  The unfortunate divisions which were known to exist some time since at Buenos Ayres it is understood still prevail.  In no part of South America has Spain made any impression on the colonies, while in many parts, and particularly in Venezuela and New Grenada, the colonies have gained strength and acquired reputation, both for the management of the war in which they have been successful and for the order of the internal administration.

The late change in the Government of Spain, by the reestablishment of the constitution of 1812, is an event which promises to be favorable to the revolution.  Under the authority of the Cortes the Congress of Angostura was invited to open a negotiation for the settlement of differences between the parties, to which it was replied that they would willingly open the negotiation provided the acknowledgment of their independence was made its basis, but not otherwise.
