The experience of several of the States, as well as that of the United States, during the period that Congress exercised the power of appropriating the public money for internal improvements is full of eloquent warnings. It seems impossible, in the nature of the subject, as connected with local representation, that the several objects presented for improvement shall be weighed according to their respective merits and appropriations confined to those whose importance would justify a tax on the whole community to effect their accomplishment.
In some of the States systems of internal improvements have been projected, consisting of roads and canals, many of which, taken separately, were not of sufficient public importance to justify a tax on the entire population of the State to effect their construction, and yet by a combination of local interests, operating on a majority of the legislature, the whole have been authorized and the States plunged into heavy debts. To an extent so ruinous has this system of legislation been carried in some portions of the Union that the people have found it necessary to their own safety and prosperity to forbid their legislatures, by constitutional restrictions, to contract public debts for such purposes without their immediate consent.
If the abuse of power has been so fatal in the States, where the systems of taxation are direct and the representatives responsible at short periods to small masses of constituents, how much greater danger of abuse is to be apprehended in the General Government, whose revenues are raised by indirect taxation and whose functionaries are responsible to the people in larger masses and for longer terms.
Regarding only objects of improvement of the nature of those embraced in this bill, how inexhaustible we shall find them. Let the imagination run along our coast from the river St. Croix to the Rio Grande and trace every river emptying into the Atlantic and Gulf of Mexico to its source; let it coast along our lakes and ascend all their tributaries; let it pass to Oregon and explore all its bays, inlets, and streams; and then let it raise the curtain of the future and contemplate the extent of this Republic and the objects of improvement it will embrace as it advances to its high destiny, and the mind will be startled at the immensity and danger of the power which the principle of this bill involves.
