deemed a part of die power itself. This results from the very nature- and design of a constitution. In giving the power, it does not intend to limit it to any one mode of exercising it, exclusive of all others. It must be obvious, (as has been already suggested,) that the means of carrying into effect the objects of a power may, nay, must be varied, in order to adapt themselves to the exigencies of the nation at different times.[1] A mode efficacious and useful in one age, or under one posture of circumstances, may be wholly vain, or even mischievous at another time. Government presupposes the existence of a perpetual mutability in its own operations on those, who are its subjects; and a perpetual flexibility in adapting itself to their wants, their interests, their habits, their occupations, and their infirmities.[2]

- ↑ The reasoning of Mr. Chief Justice Marshall on this subject, in M'Culloch v. Maryland, (4 Wheat. 316,) is so cogent and satisfactory, that we shall venture to cite it at large. After having remarked, that words have various senses, and that what is the true construction of any used in the constitution must depend upon the subject, the context, and the intentions of the people, to be gathered from the instrument, he proceeds thus:
"The subject is the execution of those great powers, on which the welfare of a nation essentially depends. It must have been the intention of those, who gave these powers, to insure, as far as human prudence could insure, their beneficial execution. This could not be done by confiding the choice of means to such narrow limits, as not to leave it in the power of congress to adopt any, which might be appropriate, and which were conducive to the end. This provision is made in a constitution intended to endure for ages to come, and, consequently, to be adapted to the various crises of human affairs. To have prescribed the means, by which government should, in all future time, execute its powers, would have been to change entirely the character of the instrument, and give it the properties of a legal code. It would have been an unwise attempt to provide, by immutable rules, for exigencies, which, if foreseen at all, must have been seen dimly, and which can be best provided for, as they occur. To have declared, that the best means shall not be used, but
