The bill authorizing a subscription to the Louisville and Portland Canal affords a striking illustration of the difficulty of withholding additional appropriations for the same object when the first erroneous step has been taken by instituting a partnership between the Government and private companies. It proposes a third subscription on the part of the United States, when each preceding one was at the time regarded as the extent of the aid which Government was to render to that work; and the accompanying bill for light houses, etc., contains an appropriation for a survey of the bed of the river, with a view to its improvement by removing the obstruction which the canal is designed to avoid. This improvement, if successful, would afford a free passage of the river and render the canal entirely useless. To such improvidence is the course of legislation subject in relation to internal improvements on local matters, even with the best intentions on the part of Congress. Although the motives which have influenced me in this matter may be already sufficiently stated, I am, never the less, induced by its importance to add a few observations of a general character. In my objections to the bills authorizing subscriptions to the Maysville and Rockville road companies I expressed my views fully in regard to the power of Congress to construct roads and canals within a State of to appropriate money for improvements of a local character. I at the same time intimated me belief that the right to make appropriations for such as were of a national character had been so generally acted upon and so long acquiesced in by the Federal and State Governments and the constituents of each as to justify its exercise on the ground of continued and uninterrupted usage, but that it was, never the less, highly expedient that appropriations even of that character should, with the exception made at the time, be deferred until the national debt is paid, and that in the mean while some general rule for the action of the Government in that respect ought to be established. These suggestions were not necessary to the decision of the question then before me, and were, I readily admit, intended to awake the attention and draw forth the opinion and observations of our constituents upon a subject of the highest importance to their interests, and one destined to exert a powerful influence upon the future operations of our political system. I know of no tribunal to which a public man in this country, in a case of doubt and difficulty, can appeal with greater advantage or more propriety than the judgment of the people; and although I must necessarily in the discharge of my official duties be governed by the dictates of my own judgment, I have no desire to conceal my anxious wish to conform as far as I can to the views of those for whom I act.
