When your preliminary interposition was asked at the close of the last session, a copy of the instructions under which Mr. McLane has acted, together with the communications which had at that time passed between him and the British Government, was laid before you. Although there has not been anything in the acts of the two Governments which requires secrecy, it was thought most proper in the then state of the negotiation to make that communication a confidential one. So soon, however, as the evidence of execution on the part of Great Britain is received the whole matter shall be laid before you, when it will be seen that the apprehension which appears to have suggested one of the provisions of the act passed at your last session, that the restoration of the trade in question might be connected with other subjects and was sought to be obtained at the sacrifice of the public interest in other particulars, was wholly unfounded, and that the change which has taken place in the views of the British Government has been induced by considerations as honorable to both parties as I trust the result will prove beneficial.

This desirable result was, it will be seen, greatly promoted by the liberal and confiding provisions of the act of Congress of the last session, by which our ports were upon the reception and annunciation by the President of the required assurance on the part of Great Britain forthwith opened to her vessels before the arrangement could be carried into effect on her part, pursuing in this act of prospective legislation a similar course to that adopted by Great Britain in abolishing, by her act of Parliament in 1825, a restriction then existing and permitting our vessels to clear from the colonies on their return voyages for any foreign country whatever before British vessels had been relieved from the restriction imposed by our law of returning directly from the United States to the colonies, a restriction which she required and expected that we should abolish. Upon each occasion a limited and temporary advantage has been given to the opposite party, but an advantage of no importance in comparison with the restoration of mutual confidence and good feeling, and the ultimate establishment of the trade upon fair principles.

It gives me unfeigned pleasure to assure you that this negotiation has been throughout characterized by the most frank and friendly spirit on the part of Great Britain, and concluded in a manner strongly indicative of a sincere desire to cultivate the best relations with the United States. To reciprocate this disposition to the fullest extent of my ability is a duty which I shall deem it a privilege to discharge.

Although the result is itself the best commentary on the services rendered to his country by our minister at the Court of St. James, it would be doing violence to my feelings were I to dismiss the subject without expressing the very high sense I entertain of the talent and exertion which have been displayed by him on the occasion.

The injury to the commerce of the United States resulting from the exclusion of our vessels from the Black Sea and the previous footing of mere sufferance upon which even the limited trade enjoyed by us with Turkey has hitherto been placed have for a long time been a source of much solicitude to this Government, and several endeavors have been made to obtain a better state of things. Sensible of the importance of the object, I felt it my duty to leave no proper means unemployed to acquire for our flag the same privileges that are enjoyed by the principal powers of Europe. Commissioners were consequently appointed to open a negotiation with the Sublime Porte. Not long after the member of the commission who went directly from the United States had sailed, the account of the treaty of Adrianople, by which one of the objects in view was supposed to be secured, reached this country. The Black Sea was understood to be opened to us. Under the supposition that this was the case, the additional facilities to be derived from the establishment of commercial regulations with the Porte were deemed of sufficient importance to require a prosecution of the negotiation as originally contemplated. It was therefore persevered in, and resulted in a treaty, which will be forthwith laid before the Senate.

By its provisions a free passage is secured, without limitation of time, to the vessels of the United States to and from the Black Sea, including the navigation thereof, and our trade with Turkey is placed on the footing of the most favored nation. The latter is an arrangement wholly independent of the treaty of Adrianople, and the former derives much value, not only from the increased security which under any circumstances it would give to the right in question, but from the fact, ascertained in the course of the negotiation, that by the construction put upon that treaty by Turkey the article relating to the passage of the Bosphorus is confined to nations having treaties with the Porte. The most friendly feelings appear to be entertained by the Sultan, and an enlightened disposition is evinced by him to foster the intercourse between the two countries by the most liberal arrangements. This disposition it will be our duty and interest to cherish.

Our relations with Russia are of the most stable character. Respect for that Empire and confidence in its friendship toward the United States have been so long entertained on our part and so carefully cherished by the present Emperor and his illustrious predecessor as to have become incorporated with the public sentiment of the United States. No means will be left unemployed on my part to promote these salutary feelings and those improvements of which the commercial intercourse between the two countries is susceptible, and which have derived increased importance from our treaty with the Sublime Porte.

I sincerely regret to inform you that our minister lately commissioned to that Court, on whose distinguished talents and great experience in public affairs I place great reliance, has been compelled by extreme indisposition to exercise a privilege which, in consideration of the extent to which his constitution had been impaired in the public service, was committed to his discretion—of leaving temporarily his post for the advantage of a more genial climate.

If, as it is to be hoped, the improvement of his health should be such as to justify him in doing so, he will repair to St. Petersburg and resume the discharge of his official duties. I have received the most satisfactory assurances that in the meantime the public interest in that quarter will be preserved from prejudice by the intercourse which he will continue through the secretary of legation with the Russian cabinet.

You are apprised, although the fact has not yet been officially announced to the House of Representatives, that a treaty was in the month of March last concluded between the United States and Denmark, by which $650,000 are secured to our citizens as an indemnity for spoliations upon their commerce in the years 1808, 1809, 1810, and 1811. This treaty was sanctioned by the Senate at the close of its last session, and it now becomes the duty of Congress to pass the necessary laws for the organization of the board of commissioners to distribute the indemnity among the claimants. It is an agreeable circumstance in this adjustment that the terms are in conformity with the previously ascertained views of the claimants themselves, thus removing all pretense for a future agitation of the subject in any form.
