"to the purposes of the local administrations as to those of the Union; and the former are at least of equal importance with the latter to the happiness of the People. It is, therefore, as necessary that the State Governments should be able to command the means of supplying their wants, as that the National Government should possess the like faculty in respect to the wants of the Union. But an indefinite power of taxation in the latter might, and probably would in time, deprive the former of the means of providing for their own necessities; and would subject them entirely to the mercy of the National Legislature. As the laws of the Union are to become the supreme law of the land; as it is to have power to pass all laws that may be necessary for carrying into execution the authorities with which it is proposed to vest it; the National Government might at any time abolish the taxes imposed for State objects, upon the pretence of an interference with its own. It might allege a necessity of doing this, in order to give efficacy to the National revenues: And thus all the resources of taxation might by degrees become the subjects of Fœderal monopoly, to the entire exclusion and destruction of the State Governments."
