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.
