When the confederated States found it convenient to modify the conditions of their association by giving to the General Government direct access in some respects to the people of the States, instead of confining it to action on the States as such, they proceeded to frame the existing Constitution, adhering steadily to one guiding thought, which was to delegate only such power as was necessary and proper to the execution of specific purposes, or, in other words, to retain as much as possible consistently with those purposes of the independent powers of the individual States.  For objects of common defense and security, they intrusted to the General Government certain carefully defined functions, leaving all others as the undelegated rights of the separate independent sovereignties.

Such is the constitutional theory of our Government, the practical observance of which has carried us, and us alone among modern republics, through nearly three generations of time without the cost of one drop of blood shed in civil war.  With freedom and concert of action, it has enabled us to contend successfully on the battlefield against foreign foes, has elevated the feeble colonies into powerful States, and has raised our industrial productions and our commerce which transports them to the level of the richest and the greatest nations of Europe.  And the admirable adaptation of our political institutions to their objects, combining local self-government with aggregate strength, has established the practicability of a government like ours to cover a continent with confederate states.

The Congress of the United States is in effect that congress of sovereignties which good men in the Old World have sought for, but could never attain, and which imparts to America an exemption from the mutable leagues for common action, from the wars, the mutual invasions, and vague aspirations after the balance of power which convulse from time to time the Governments of Europe.  Our cooperative action rests in the conditions of permanent confederation prescribed by the Constitution.  Our balance of power is in the separate reserved rights of the States and their equal representation in the Senate.  That independent sovereignty in every one of the States, with its reserved rights of local self-government assured to each by their coequal power in the Senate, was the fundamental condition of the Constitution.  Without it the Union would never have existed.  However desirous the larger States might be to reorganize the Government so as to give to their population its proportionate weight in the common counsels, they knew it was impossible unless they conceded to the smaller ones authority to exercise at least a negative influence on all the measures of the Government, whether legislative or executive, through their equal representation in the Senate.  Indeed, the larger States themselves could not have failed to perceive that the same power was equally necessary to them for the security of their
