The treaty between the United States and Great Britain of the 5th of June, 1854, which went into effective operation in 1855, put an end to causes of irritation between the two countries, by securing to the United States the right of fishery on the coast of the British North American Provinces, with advantages equal to those enjoyed by British subjects. Besides the signal benefits of this treaty to a large class of our citizens engaged in a pursuit connected to no inconsiderable degree with our national prosperity and strength, it has had a favorable effect upon other interests in the provision it made for reciprocal freedom of trade between the United States and the British Provinces in America.

The exports of domestic articles to those Provinces during the last year amounted to more than $22,000,000, exceeding those of the preceding year by nearly $7,000,000; and the imports therefrom during the same period amounted to more than twenty-one million, an increase of six million upon those of the previous year.

The improved condition of this branch of our commerce is mainly attributable to the above-mentioned treaty.

Provision was made in the first article of that treaty for a commission to designate the mouths of rivers to which the common right of fishery on the coast of the United States and the British Provinces was not to extend. This commission has been employed a part of two seasons, but without much progress in accomplishing the object for which it was instituted, in consequence of a serious difference of opinion between the commissioners, not only as to the precise point where the rivers terminate, but in many instances as to what constitutes a river. These difficulties, however, may be overcome by resort to the umpirage provided for by the treaty.

The efforts perseveringly prosecuted since the commencement of my Administration to relieve our trade to the Baltic from the exaction of Sound dues by Denmark have not yet been attended with success. Other governments have also sought to obtain a like relief to their commerce, and Denmark was thus induced to propose an arrangement to all the European powers interested in the subject, and the manner in which her proposition was received warranting her to believe that a satisfactory arrangement with them could soon be concluded, she made a strong appeal to this Government for temporary suspension of definite action on its part, in consideration of the embarrassment which might result to her European negotiations by an immediate adjustment of the question with the United States. This request has been acceded to upon the condition that the sums collected after the 16th of June last and until the 16th of June next from vessels and cargoes belonging to our merchants are to be considered as paid under protest and subject to future adjustment. There is reason to believe that an arrangement between Denmark and the maritime powers of Europe on the subject will be soon concluded, and that the pending negotiation with the United States may then be resumed and terminated in a satisfactory manner.

With Spain no new difficulties have arisen, nor has much progress been made in the adjustment of pending ones.

Negotiations entered into for the purpose of relieving our commercial intercourse with the island of Cuba of some of its burdens and providing for the more speedy settlement of local disputes growing out of that intercourse have not yet been attended with any results.

Soon after the commencement of the late war in Europe this Government submitted to the consideration of all maritime nations two principles for the security of neutral commerce—one that the neutral flag should cover enemies' goods, except articles contraband of war, and the other that neutral property on board merchant vessels of belligerents should be exempt from condemnation, with the exception of contraband articles. These were not presented as new rules of international law, having been generally claimed by neutrals, though not always admitted by belligerents. One of the parties to the war (Russia), as well as several neutral powers, promptly acceded to these propositions, and the two other principal belligerents (Great Britain and France) having consented to observe them for the present occasion, a favorable opportunity seemed to be presented for obtaining a general recognition of them, both in Europe and America.

But Great Britain and France, in common with most of the States of Europe, while forbearing to reject, did not affirmatively act upon the overtures of the United States.

While the question was in this position the representatives of Russia, France, Great Britain, Austria, Prussia, Sardinia, and Turkey, assembled at Paris, took into consideration the subject of maritime rights, and put forth a declaration containing the two principles which this Government had submitted nearly two years before to the consideration of maritime powers, and adding thereto the following propositions: "Privateering is and remains abolished," and "Blockades in order to be binding must be effective; that is to say, maintained by a force sufficient really to prevent access to the coast of the enemy;" and to the declaration thus composed of four points, two of which had already been proposed by the United States, this Government has been invited to accede by all the powers represented at Paris except Great Britain and Turkey. To the last of the two additional propositions—that in relation to blockades—there can certainly be no objection. It is merely the definition of what shall constitute the effectual investment of a blockaded place, a definition for which this Government has always contended, claiming indemnity for losses where a practical violation of the rule thus defined has been injurious to our commerce. As to the remaining, article of the declaration of the conference of Paris, that "privateering is and remains abolished," I certainly can not ascribe to the powers represented in the conference of Paris any but liberal and philanthropic views in the attempt to change the unquestionable rule of maritime law in regard to privateering. Their proposition was doubtless intended to imply approval of the principle that private property upon the ocean, although it might belong to the citizens of a belligerent state, should be exempted from capture; and had that proposition been so framed as to give full effect to the principle, it would have received my ready assent on behalf of the United States. But the measure proposed is inadequate to that purpose. It is true that if adopted private property upon the ocean would be withdrawn from one mode of plunder, but left exposed meanwhile to another mode, which could be used with increased effectiveness. The aggressive capacity of great naval powers would be thereby augmented, while the defensive ability of others would be reduced. Though the surrender of the means of prosecuting hostilities by employing privateers, as proposed by the conference of Paris, is mutual in terms, yet in practical effect it would be the relinquishment of a right of little value to one class of states, but of essential importance to another and a far larger class. It ought not to have been anticipated that a measure so inadequate to the accomplishment of the proposed object and so unequal in its operation would receive the assent of all maritime powers. Private property would be still left to the depredations of the public armed cruisers.
