I will now proceed to the fifth source from which the power is said to be derived, viz, the power to make all laws which shall be necessary and proper for carrying into execution all the powers vested by the Constitution in the Government of the United States or in any department or officer thereof. This is the seventeenth and last of the enumerated powers granted to Congress. I have always considered this power as having been granted on a principle of greater caution to secure the complete execution of all the powers which had been vested in the General Government. It contains no distinct and specific power, as every other grant does, such as to lay and collect taxes, to declare war, to regulate commerce, and the like. Looking to the whole scheme of the General Government, it gives to Congress authority to make all laws which should be deemed necessary and proper for carrying all its powers into effect. My impression has been invariably that this power would have existed substantially if this grant had not been made; for why is any power granted unless it be to be executed when required, and how can it be executed under our Government unless it be by laws necessary and proper for the purpose--that is, well adapted to the end? It is a principle universally admitted that a grant of a power conveys as a necessary consequence or incident to it the means of carrying it into effect by a fair construction of its import. In the formation, however, of the Constitution, which was to act directly upon the people and be paramount to the extent of its powers to the constitutions of the States, it was wise in its framers to leave nothing to implication which might be reduced to certainty. It is known that all power which rests solely on that ground has been systematically and zealously opposed under all governments with which we have any acquaintance; and it was reasonable to presume that under our system, where there was a division of the sovereignty between the two independent governments, the measures of the General Government would excite equal jealousy and produce an opposition not less systematic, though, perhaps, less violent. Hence the policy by the framers of our Government of securing by a fundamental declaration in the Constitution a principle which in all other governments had been left to implication only. The terms "necessary" and "proper" secure to the powers of all the grants to which the authority given in this is applicable a fair and sound construction, which is equally binding as a rule on both Governments and on all their departments.
