If our power over means is so absolute that the Supreme Court will not call in question the constitutionality of an act of Congress the subject of which "is not prohibited, and is really calculated to effect any of the objects intrusted to the Government," although, as in the case before me, it takes away powers expressly granted to Congress and rights scrupulously reserved to the States, it becomes us to proceed in our legislation with the utmost caution. Though not directly, our own powers and the rights of the States may be indirectly legislated away in the use of means to execute substantive powers. We may not enact that Congress shall not have the power of exclusive legislation over the District of Columbia, but we may pledge the faith of the United States that as a means of executing other powers it shall not be exercised for twenty years or forever. We may not pass an act prohibiting the States to tax the banking business carried on within their limits, but we may, as a means of executing our powers over other objects, place that business in the hands of our agents and then declare it exempt from State taxation in their hands. Thus may our own powers and the rights of the States, which we can not directly curtail or invade, be frittered away and extinguished in the use of means employed by us to execute other powers. That a bank of the United States, competent to all the duties which may be required by the Government, might be so organized as not to infringe on our own delegated powers or the reserved rights of the States I do not entertain a doubt. Had the Executive been called upon to furnish the project of such an institution, the duty would have been cheerfully performed. In the absence of such a call it was obviously proper that he should confine himself to pointing out those prominent features in the act; presented which in his opinion make it incompatible with the Constitution and sound policy. A general discussion will now take place, eliciting new light and settling important principles; and a new Congress, elected in the midst of such discussion, and furnishing an equal representation of the people according to the last census, will bear to the Capitol the verdict of public opinion, and, I doubt not, bring this important question to a satisfactory result. Under such circumstances the bank comes forward and asks a renewal of its charter for a term of fifteen years upon conditions which not only operate as a gratuity to the stockholders of many millions of dollars, but will sanction any abuses and legalize any encroachments.
