If, then, the right to raise and appropriate the public money is not restricted to the expenditures under the other specific grants according to a strict construction of their powers, respectively, is there no limitation to it? Have Congress a right to raise and appropriate the money to any and to every purpose according to their will and pleasure? They certainly have not. The Government of the United States is a limited Government, instituted for great national purposes, and for those only. Other interests are committed to the States, whose duty it is to provide for them. Each government should look to the great and essential purposes for which it was instituted and confine itself to those purposes. A State government will rarely if ever apply money to national purposes without making it a charge to the nation. The people of the State would not permit it. Nor will Congress be apt to apply money in aid of the State administrations for purposes strictly local in which the nation at large has no interest, although the State should desire it. The people of the other States would condemn it. They would declare that Congress had no right to tax them for such a purpose, and dismiss at the next election such of their representatives as had voted for the measure, especially if it should be severely felt. I do not think that in offices of this kind there is much danger of the two Governments mistaking their interests or their duties. I rather expect that they would soon have a clear and distinct understanding of them and move on in great harmony. Good roads and canals will promote many very important national purposes. They will facilitate the operations of war, the movements of troops, the transportation of cannon, of provisions, and every warlike store, much to our advantage and to the disadvantage of the enemy in time of war. Good roads will facilitate the transportation of the mail, and thereby promote the purposes of commerce and political intelligence among the people. They will by being properly directed to these objects enhance the value of our vacant lands, a treasure of vast resource to the nation. To the appropriation of the public money to improvements having these objects in view and carried to a certain extent I do not see any well-founded constitutional objection.
