"It is obvious, therefore, that the utmost caution is necessary in the exercise of this right claimed by Great Britain. While we have recourse to the necessary, and, indeed, the only means for detecting imposture, the practice will be carefully guarded and limited to cases of strong suspicion. The undersigned begs to assure Mr. Stevenson that the most precise and positive instructions have been issued to her Majesty's officers on this subject."
Such are the words of the British claim or pretension; and it stood in
this form at the delivery of the President's message to Congress in
December last; a message in which you are pleased to say that the
British pretension was promptly met and firmly resisted.
I may now proceed to a more particular examination of the objections which you make to the treaty.
You observe that you think a just self-respect required of the government of the United States to demand of Lord Ashburton a distinct renunciation of the British claim to search our vessels previous to entering into any negotiation. The government has thought otherwise; and this appears to be your main objection to the treaty, if, indeed, it be not the only one which is clearly and distinctly stated. The government of the United States supposed that, in this respect, it stood in a position in which it had no occasion to demand any thing, or ask for any thing, of England. The British pretension, whatever it was, or however extensive, was well known to the President at the date of his message to Congress at the opening of the last session. And I must be allowed to remind you how the President treated this subject in that communication.
"However desirous the United States may be," said he, "for the suppression of the slave-trade, they cannot consent to interpolations into the maritime code at the mere will and pleasure of other governments. We deny the right of any such interpolation to any one, or all the nations of the earth, without our consent. We claim to have a voice in all amendments or alterations of that code; and when we are given to understand, as in this instance, by a foreign government, that its treaties with other nations cannot be executed without the establishment and enforcement of new principles of maritime police, to be applied without our consent, we must employ a language neither of equivocal import nor susceptible of misconstruction. American citizens prosecuting a lawful commerce in the African seas, under the flag of their country, are not responsible for the abuse or unlawful use of that flag by others; nor can they rightfully, on account of any such alleged abuses, be interrupted, molested, or detained while on the ocean; and if thus molested and detained while pursuing honest voyages in the usual way, and violating no law themselves, they are unquestionably entitled to indemnity."
This declaration of the President stands: not a syllable of it has been, or will be, retracted. The principles which it announces rest on their inherent justice and propriety, on their conformity to public law, and, so far as we are concerned, on the determination and ability of the country to maintain them. To these principles the government is pledged, and that pledge it will be at all times ready to redeem.
But what is your own language on this point? You say, "This claim (the British claim), thus asserted and supported, was promptly met and firmly repelled by the President in his message at the commencement of the last session of Congress; and in your letter to me approving the course I had adopted in relation to the question of the ratification by France of the quintuple treaty, you consider the principles of that message as the established policy of the government." And you add, "So far, our national dignity was uncompromitted." If this be so, what is there which has since occurred to compromit this dignity? You shall yourself be judge of this; because you say, in a subsequent part of your letter, that "the mutual rights of the parties are in this respect wholly untouched." If, then, the British pretension had been promptly met and firmly repelled by the President's message; if, so far, our national dignity had not been compromitted; and if, as you further say, our rights remain wholly untouched by any subsequent act or proceeding, what ground is there on which to found complaint against the treaty?
But your sentiments on this point do not concur with the opinions of your government. That government is of opinion that the sentiments of the message, which you so highly approve, are reaffirmed and corroborated by the treaty, and the correspondence accompanying it. The very object sought to be obtained, in proposing the mode adopted for abolishing the slave-trade, was to take away all pretence whatever for interrupting lawful commerce by the visitation of American vessels. Allow me to refer you, on this point, to the following passage in the message of the President to the Senate, accompanying the treaty:—
"In my message at the commencement of the present session of Congress, I endeavored to state the principles which this government supports respecting the right of search and the immunity of flags. Desirous of maintaining those principles fully, at the same time that existing obligations should be fulfilled, I have thought it most consistent with the dignity and honor of the country that it should execute its own laws and perform its own obligations by its own means and its own power. The examination or visitation of the merchant-vessels of one nation by the cruisers of another, for any purposes except those known and acknowledged by the law of nations, under whatever restraints or regulations it may take place, may lead to dangerous results. It is far better by other means to supersede any supposed necessity, or any motive, for such examination or visit. Interference with a merchant-vessel by an armed cruiser is always a delicate proceeding, apt to touch the point of national honor, as well as to affect the interests of individuals. It has been thought, therefore, expedient, not only in accordance with the stipulations of the treaty of Ghent, but at the same time as removing all pretext on the part of others for violating the immunities of the American flag upon the seas, as they exist and are defined by the law of nations, to enter into the articles now submitted to the Senate.
"The treaty which I now submit to you proposes no alteration, mitigation, or modification of the rules of the law of nations. It provides simply, that each of the two governments shall maintain on the coast of Africa a sufficient squadron to enforce, separately and respectively, the laws, rights, and obligations of the two countries for the suppression of the slave-trade."
