"It may be assumed that this authority is incident to the power granted to Congress by the Constitution, as recently amended, to enforce, by appropriate legislation, the article declaring that 'neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.' It can not, however, be justly claimed that, with a view to the enforcement of this article of the Constitution, there is, at present, any necessity for the exercise of all the powers which this bill confers. "Slavery has been abolished, and, at present, nowhere exists within the jurisdiction of the United States; nor has there been, nor is it likely there will be, any attempt to revive it by the people of the States. If, however, any such attempt shall be made, it will then become the duty of the General Government to exercise any and all incidental powers necessary and proper to maintain inviolate this great constitutional law of freedom. "The fourth section of the bill provides that officers and agents of the Freedmen's Bureau shall be empowered to make arrests, and also that other officers may be specially commissioned for that purpose by the President of the United States. It also authorizes circuit courts of the United States and the superior courts of the Territories to appoint, without limitation, commissioners, who are to be charged with the performance of _quasi_ judicial duties. The fifth section empowers the commissioners so to be selected by the courts to appoint, in writing, under their hands, one or more suitable persons, from time to time, to execute warrants and other processes described by the bill. These numerous official agents are made to constitute a sort of police, in addition to the military, and are authorized to summon a _posse comitatus_ and even to call to their aid such portion of the land and naval forces of the United States, or of the militia, 'as may be necessary to the performance of the duty with which they are charged.'
