Negotiations are pending with Denmark to discontinue the practice of levying tolls on our vessels and their cargoes passing through the Sound. I do not doubt that we can claim exemption therefrom as a matter of right. It is admitted on all hands that this exaction is sanctioned, not by the general principles of the law of nations, but only by special conventions which most of the commercial nations have entered into with Denmark. The fifth article of our treaty of 1826 with Denmark provides that there shall not be paid on the vessels of the United States and their cargoes when passing through the Sound higher duties than those of the most favored nations. This may be regarded as an implied agreement to submit to the tolls during the continuance of the treaty, and consequently may embarrass the assertion of our right to be released therefrom. There are also other provisions in the treaty which ought to be modified. It was to remain in force for ten years and until one year after either party should give notice to the other of intention to terminate it. I deem it expedient that the contemplated notice should be given to the Government of Denmark. The naval expedition dispatched about two years since for the purpose of establishing relations with the Empire of Japan has been ably and skillfully conducted to a successful termination by the officer to whom it was intrusted. A treaty opening certain of the ports of that populous country has been negotiated, and in order to give full effect thereto it only remains to exchange ratifications and adopt requisite commercial regulations.
