In 1806, on the same principle, President Jefferson broke up the Burr conspiracy by issuing "orders for the employment of such force, either of the regulars or of the militia, and by such proceedings of the civil authorities, * * * as might enable them to suppress effectually the further progress of the enterprise." And it was under the same authority that President Jackson crushed nullification in South Carolina and that President Lincoln issued his call for troops to save the Union in 1861. On numerous other occasions of less significance, under probably every Administration, and certainly under the present, this power has been usefully exerted to enforce the laws, without objection by any party in the country, and almost without attracting public attention. The great elementary constitutional principle which was the foundation of the original statute of 1792, and which has been its essence in the various forms it has assumed since its first adoption, is that the Government of the United States possesses under the Constitution, in full measure, the power of self-protection by its own agencies, altogether independent of State authority, and, if need be, against the hostility of State governments. It should remain embodied in our statutes unimpaired, as it has been from the very origin of the Government. It should be regarded as hardly less valuable or less sacred than a provision of the Constitution itself. There are many other important statutes containing provisions that are liable to be suspended or annulled at the times and places of holding elections if the bill before me should become a law. I do not undertake to furnish a list of them. Many of them--perhaps the most of them--have been set forth in the debates on this measure. They relate to extradition, to crimes against the election laws, to quarantine regulations, to neutrality, to Indian reservations, to the civil rights of citizens, and to other subjects. In regard to them all it may be safely said that the meaning and effect of this bill is to take from the General Government an important part of its power to enforce the laws.
