A brief inquiry will show that it is consistent with the Constitution of the United States, and in no respect interferes with the organization of the National Militia. That Constitution provides for organizing, arming, and disciplining the militia, and gives Congress full power over the subject,--in which particular, be it observed, it is clearly distinguishable from that of fugitive slaves, over whom no such power is given. To be more explicit, I will read the clause. It is found in the long list of enumerated powers of Congress, and is as follows: "The Congress shall have power to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States, reserving to the States respectively the appointment of the officers, and the authority of training the militia according to the discipline prescribed by Congress." And then, at the close of the section, it is further declared, that Congress shall have power "to make _all laws which shall be necessary and proper_ for carrying into execution the foregoing powers." In pursuance of this power, Congress has proceeded, by various laws, "to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States." The earliest of these laws, still in force, is entitled "An act more effectually to provide for the national defence, by _establishing an uniform_ militia throughout the United States."[3] This was followed by several acts in addition. Congress, then, has undertaken to exercise the power of "organizing" the militia under the Constitution. Here the question arises, to what extent, if any, this power, when already exercised by Congress, is exclusive in character. Among the powers delegated to Congress there may be some not for the time being exercised. For instance, there is the power "to fix the standard of weights and measures." Practically, this has never been exercised by Congress; but it is left to each State within its own jurisdiction. On the other hand, there is a power, belonging to the same group, "to establish uniform laws on the subject of bankruptcies throughout the United States," which, when exercised by Congress, has been held so far exclusive as to avoid at once all the bankrupt and insolvent laws of the several States.
