The words in the message at the opening of the session which are complained of, it is supposed, are the following: "Although Lord Aberdeen, in his correspondence with the American envoys at London, expressly disclaimed all right to detain an American ship on the high seas, even if found with a cargo of slaves on board, and restricted the British pretension to a mere claim to visit and inquire, yet it could not well be discerned by the Executive of the United States how such visit and inquiry could be made without detention on the voyage, and consequent interruption to the trade. It was regarded as the right of search, presented only in a new form and expressed in different words; and I therefore felt it to be my duty distinctly to declare, in my annual message to Congress, that no such concession could be made, and that the United States had both the will and the ability to enforce their own laws, and to protect their flag from being used for purposes wholly forbidden by those laws, and obnoxious to the moral censure of the world."
This statement would tend, as Lord Aberdeen thinks, to convey the supposition, not only that the question of the right of search had been disavowed by the British plenipotentiary at Washington, but that Great Britain had made concessions on that point.
Lord Aberdeen is entirely correct in saying that the claim of a right of search was not discussed during the late negotiation, and that neither was any concession required by this government, nor made by that of her Britannic Majesty.
The eighth and ninth articles of the treaty of Washington constitute a mutual stipulation for concerted efforts to abolish the African slave-trade. The stipulation, it may be admitted, has no other effects on the pretensions of either party than this: Great Britain had claimed as a right that which this government could not admit to be a right, and, in the exercise of a just and proper spirit of amity, a mode was resorted to which might render unnecessary both the assertion and the denial of such claim.
There probably are those who think that what Lord Aberdeen calls a right of visit, and which he attempts to distinguish from the right of search, ought to have been expressly acknowledged by the government of the United States. At the same time, there are those on the other side who think that the formal surrender of such right of visit should have been demanded by the United States as a precedent condition to the negotiation for treaty stipulations on the subject of the African slave-trade. But the treaty neither asserts the claim in terms, nor denies the claim in terms; it neither formally insists upon it, nor formally renounces it. Still, the whole proceeding shows that the object of the stipulation was to avoid such differences and disputes as had already arisen, and the serious practical evils and inconveniences which, it cannot be denied, are always liable to result from the practice which Great Britain had asserted to be lawful. These evils and inconveniences had been acknowledged by both governments. They had been such as to cause much irritation, and to threaten to disturb the amicable sentiments which prevailed between them. Both governments were sincerely desirous of abolishing the slave-trade; both governments were equally desirous of avoiding occasion of complaint by their respective citizens and subjects; and both governments regarded the eighth and ninth articles as effectual for their avowed purpose, and likely, at the same time, to preserve all friendly relations, and to take away causes of future individual complaints. The treaty of Washington was intended to fulfil the obligations entered into by the treaty of Ghent. It stands by itself; is clear and intelligible. It speaks its own language, and manifests its own purpose. It needs no interpretation, and requires no comment. As a fact, as an important occurrence in national intercourse, it may have important bearings on existing questions respecting the public law; and individuals, or perhaps governments, may not agree as to what these bearings really are. Great Britain has discussions, if not controversies, with other great European states upon the subject of visit or search. These states will naturally make their own commentary on the treaty of Washington, and draw their own inferences from the fact that such a treaty has been entered into. Its stipulations, in the mean time, are plain, explicit, and satisfactory to both parties, and will be fulfilled on the part of the United States, and, it is not doubted, on the part of Great Britain also, with the utmost good faith.
Holding this to be the true character of the treaty, I might, perhaps, excuse myself from entering into the consideration of the grounds of that claim of a right to visit merchant-ships for certain purposes, in time of peace, which Lord Aberdeen asserts for the British government, and declares that it can never surrender. But I deem it right, nevertheless, and no more than justly respectful toward the British government, not to leave the point without remark.
In his recent message to Congress, the President, referring to the language of Lord Aberdeen in his note to Mr. Everett of the 20th of December, 1841, and in his late despatch to Mr. Fox, says: "These declarations may well lead us to doubt whether the apparent difference between the two governments is not rather one of definition than of principle."
Lord Aberdeen, in his note to you of the 20th of December, says: "The undersigned again renounces, as he has already done in the most explicit terms, any right on the part of the British government to search American vessels in time of peace. The right of search, except when specially conceded by treaty, is a pure belligerent right, and can have no existence on the high seas during peace. The undersigned apprehends, however, that the right of search is not confined to the verification of the nationality of the vessel, but also extends to the object of the voyage and the nature of the cargo. The sole purpose of the British cruisers is to ascertain whether the vessels they meet with are really American or not. The right asserted has, in truth, no resemblance to the right of search, either in principle or practice. It is simply a right to satisfy the party who has a legitimate interest in knowing the truth, that the vessel actually is what her colors announce. This right we concede as freely as we exercise. The British cruisers are not instructed to detain American vessels under any circumstances whatever; on the contrary, they are ordered to abstain from all interference with them, be they slavers or otherwise. But where reasonable suspicion exists that the American flag has been abused for the purpose of covering the vessel of another nation, it would appear scarcely credible, had it not been made manifest by the repeated protestations of their representative, that the government of the United States, which has stigmatized and abolished the trade itself, should object to the adoption of such means as are indispensably necessary for ascertaining the truth."
And in his recent despatch to Mr. Fox his Lordship further says: "That the President might be assured that Great Britain would always respect the just claims of the United States. That the British government made no pretension to interfere in any manner whatever, either by detention, visit, or search, with vessels of the United States, known or believed to be such, but that it still maintained, and would exercise when necessary, its own right to ascertain the genuineness of any flag which a suspected vessel might bear; that if, in the exercise of this right, either from involuntary error, or in spite of every precaution, loss or injury should be sustained, a prompt reparation would be afforded; but that it should entertain, for a single instant, the notion of abandoning the right itself, would be quite impossible."
This, then, is the British claim, as asserted by her Majesty's government.
