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. In the case of offenders fleeing from Canada into the United States, the governors of States are often applied to for their surrender, and questions of a very embarrassing nature arise from these applications. It has been thought highly important, therefore, to provide for the whole case by a proper treaty stipulation. The article on the subject in the proposed treaty is carefully confined to such offenses as all mankind agree to regard as heinous and destructive of the security of life and property. In this careful and specific enumeration of crimes the object has been to exclude all political offenses or criminal charges arising from wars or intestine commotions. Treason, misprision of treason, libels, desertion from military service, and other offenses of similar character are excluded. And lest some unforeseen inconvenience or unexpected abuse should arise from the stipulation rendering its continuance in the opinion of one or both of the parties not longer desirable, it is left in the power of either to put an end to it at will.
