By the sixteenth and seventeenth sections of the same statute two distinct processes are prescribed, by either or both of which the above enactment may be carried into execution. By the first it is declared to be lawful for the military force of the United States to apprehend every person found in the Indian country over and beyond the boundary line between the United States and the Indian tribes in violation of any of the provisions or regulations of the act, and immediately to convey them, in the nearest convenient and safe route, to the civil authority of the United States in some of the three next adjoining States or districts, to be proceeded against in due course of law. By the second it is directed that if any person charged with the violation of any of the provisions or regulations of the act shall be found within any of the United States or either of their territorial districts such offender may be there apprehended and brought to trial in the same manner as if such crime or offense had been committed within such State or district; and that it shall be the duty of the military force of the United States, when called upon by the civil magistrate or any proper officer or other person duly authorized for that purpose and having a lawful warrant, to aid and assist such magistrate, officer, or other person so authorized in arresting such offender and committing him to safe custody for trial according to law. The first of these processes is adapted to the arrest of the trespasser upon Indian territories on the spot and in the act of committing the offense; but as it applies the action of the Government of the United States to places where the civil process of the law has no authorized course, it is committed entirely to the functions of the military force to arrest the person of the offender, and after bringing him within the reach of the jurisdiction of the courts there to deliver him into custody for trial. The second makes the violator of the law amenable only after his offense has been consummated, and when he has returned within the civil jurisdiction of the Union. This process, in the first instance, is merely of a civil character, but may in like manner be enforced by calling in, if necessary, the aid of the military force.
