Among the causes of regret, however, which are inseparable from the delay attending this transaction it is proper to state that satisfactory information has been received that measures have been recently adopted by designing persons to convert certain parts of the Province of East Florida into depots for the reception of foreign goods, from whence to smuggle them into the United States. By opening a port within the limits of Florida, immediately on our boundary where there was no settlement, the object could not be misunderstood. An early accommodation of differences will, it is hoped, prevent all such fraudulent and pernicious practices, and place the relations of the two countries on a very amicable and permanent basis. The commercial relations between the United States and the British colonies in the West Indies and on this continent have undergone no change, the British Government still preferring to leave that commerce under the restriction heretofore imposed on it on each side. It is satisfactory to recollect that the restraints resorted to by the United States were defensive only, intended to prevent a monopoly under British regulations in favor of Great Britain, as it likewise is to know that the experiment is advancing in a spirit of amity between the parties. 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.
