The examination or visitation of the merchant vessels of one nation by the cruisers of another for any purpose 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.

Another consideration of great importance has recommended this mode of fulfilling the duties and obligations of the country.  Our commerce along the western coast of Africa is extensive, and supposed to be increasing.  There is reason to think that in many cases those engaged in it have met with interruptions and annoyances caused by the jealousy and instigation of rivals engaged in the same trade.  Many complaints on this subject have reached the Government.  A respectable naval force on the coast is the natural resort and security against further occurrences of this kind.

The surrender to justice of persons who, having committed high crimes, seek an asylum in the territories of a neighboring nation would seem to be an act due to the cause of general justice and properly belonging to the present state of civilization and intercourse.  The British Provinces of North America are separated from the States of the Union by a line of several thousand miles, and along portions of this line the amount of population on either side is quite considerable, while the passage of the boundary is always easy.

Offenders against the law on the one side transfer themselves to the other.  Sometimes, with great difficulty, they are brought to justice, but very often they wholly escape.  A consciousness of immunity from the power of avoiding justice in this way instigates the unprincipled and reckless to the commission of offenses, and the peace and good neighborhood of the border are consequently often disturbed.
