things ordained and established by it.  To assume that anything more can be designed by the language of the preamble would be to convert all the body of the Constitution, with its carefully weighed enumerations and limitations, into mere surplusage.  The same may be said of the phrase in the grant of the power to Congress “to pay the debts and provide for the common defense and general welfare of the United States;” or, to construe the words more exactly, they are not significant of grant or concession, but of restriction of the specific grants, having the effect of saying that in laying and collecting taxes for each of the precise objects of power granted to the General Government Congress must exercise any such definite and undoubted power in strict subordination to the purpose of the common defense and general welfare of all the States.

There being no specific grant in the Constitution of a power to sanction appropriations for internal improvements, and no general provision broad enough to cover any such indefinite object, it becomes necessary to look for particular powers to which one or another of the things included in the phrase “internal improvements” may be referred.

In the discussions of this question by the advocates of the organization of a “general system of internal improvements” under the auspices of the Federal Government, reliance is had for the justification of the measure on several of the powers expressly granted to Congress, such as to establish post-offices and post-roads, to declare war, to provide and maintain a navy, to raise and support armies, to regulate commerce, and to dispose of the territory and other public property of the United States,

As to the last of these sources of power, that of disposing of the territory and other public property of the United States, it may be conceded that it authorizes Congress, in the management of the public property, to make improvements essential to the successful execution of the trust; but this must be the primary object of any such improvement, and it would be an abuse of the trust to sacrifice the interest of the property to incidental purposes.

As to the other assumed sources of a general power over internal improvements, they being specific powers of which this is supposed to be the incident, if the framers of the Constitution, wise and thoughtful men as they were, intended to confer on Congress the power over a subject so wide as the whole field of internal improvements, it is remarkable that they did not use language clearly to express it, or, in other words, that they did not give it as a distinct and substantive power instead of making it the implied incident of some other one; for such is the magnitude of the supposed incidental power and its capacity of expansion that any system established under it would exceed each of the others in the amount of expenditure and number of the persons employed, which would thus be thrown upon the General Government.
