power granted in a frame of government is not contemplated to be exhausted in a single exertion of it, or uno flatu. It is intended for free and permanent exercise; and if the discretion of the functionaries, who are to exercise it, is not limited, that discretion, especially, as those functionaries must necessarily change, must be co-extensive with the power itself. Take, for instance, the power to make war. In one age, this would authorize the purchase and employment of the weapons then ordinarily used for this purpose. But suppose these weapons are wholly laid aside, and others substituted, more efficient and powerful; is the government prohibited from employing the new modes of offence and defence? Surely not. The invention of gunpowder superseded the old modes of warfare, and may perhaps, by future inventions, be superseded in its turn. No one can seriously doubt, that the new modes would be within the scope of the power to make war, if they were appropriate to the end. It would, indeed, be a most extraordinary mode of interpretation of the constitution, to give such a restrictive meaning to its powers, as should obstruct their fair operation. A power being given, it is the interest of the nation to facilitate its execution. It can never be their interest, and cannot be presumed to be their intention, to clog and embarrass its execution, by withholding the most appropriate means. There can be no reasonable ground for preferring that construction, which would render the operations of the government difficult, hazardous, and expensive; or for imputing to the framers of the constitution a design to impede the exercise of its powers, by withholding a choice of means.[1]
