Regarding the bill authorizing a subscription to the stock of the Maysville and Lexington Turn Pike Company as the entering wedge of a system which, however weak at first, might soon become strong enough to rive the bands of the Union asunder, and believing that if its passage was acquiesced in by the Executive and the people there would no longer be any limitation upon the authority of the General Government in respect to the appropriation of money for such objects, I deemed it an imperative duty to withhold from it the Executive approval.

Although from the obviously local character of that work I might well have contented myself with a refusal to approve the bill upon that ground, yet sensible of the vital importance of the subject, and anxious that my views and opinions in regard to the whole matter should be fully understood by Congress and by my constituents, I felt it my duty to go further. I therefore embraced that early occasion to apprise Congress that in my opinion the Constitution did not confer upon it the power to authorize the construction of ordinary roads and canals within the limits of a State and to say, respectfully, that no bill admitting such a power could receive my official sanction. I did so in the confident expectation that the speedy settlement of the public mind upon the whole subject would be greatly facilitated by the difference between the two Houses and myself, and that the harmonious action of the several departments of the Federal Government in regard to it would be ultimately secured.

So far, at least, as it regards this branch of the subject, my best hopes have been realized. Nearly four years have elapsed, and several sessions of Congress have intervened, and no attempt within my recollection has been made to induce Congress to exercise this power. The applications for the construction of roads and canals which were formerly multiplied upon your files are no longer presented, and we have good reason to infer that the current public sentiment has become so decided against the pretension as effectually to discourage its reassertion. So thinking, I derive the greatest satisfaction from the conviction that thus much at least has been secured upon this important and embarrassing subject.

From attempts to appropriate the national funds to objects which are confessedly of a local character we can not, I trust, have anything further to apprehend. My views in regard to the expediency of making appropriations for works which are claimed to be of a national character and prosecuted under State authority--assuming that Congress have the right to do so--were stated in my annual message to Congress in 1830, and also in that containing my objections to the Maysville road bill.

So thoroughly convinced am I that no such appropriations ought to be made by Congress until a suitable constitutional provision is made upon the subject, and so essential do I regard the point to the highest interests of our country, that I could not consider myself as discharging my duty to my constituents in giving the Executive sanction to any bill containing such an appropriation. If the people of the United States desire that the public Treasury shall be resorted to for the means to prosecute such works, they will concur in an amendment of the Constitution prescribing a rule by which the national character of the works is to be tested, and by which the greatest practicable equality of benefits may be secured to each member of the Confederacy. The effects of such a regulation would be most salutary in preventing unprofitable expenditures, in securing our legislation from the pernicious consequences of a scramble for the favors of Government, and in repressing the spirit of discontent which must inevitably arise from an unequal distribution of treasures which belong alike to all.

There is another class of appropriations for what may be called, without impropriety, internal improvements, which have always been regarded as standing upon different grounds from those to which I have referred. I allude to such as have for their object the improvement of our harbors, the removal of partial and temporary obstructions in our navigable rivers, for the facility and security of our foreign commerce. The grounds upon which I distinguished appropriations of this character from others have already been stated to Congress. I will now only add that at the 1st session of Congress under the new Constitution it was provided by law that all expenses which should accrue from and after the 15th day of August, 1789, in the necessary support and maintenance and repairs of all light houses, beacons, buoys, and public piers erected, placed, or sunk before the passage of the act within any bay, inlet, harbor, or port of the United States, for rendering the navigation thereof easy and safe, should be defrayed out of the Treasury of the United States, and, further, that it should be the duty of the Secretary of the Treasury to provide by contracts, with the approbation of the President, for rebuilding when necessary and keeping in good repair the light houses, beacons, buoys, and public piers in the several States, and for furnishing them with supplies.

Appropriations for similar objects have been continued from that time to the present without interruption or dispute. As a natural consequence of the increase and extension of our foreign commerce, ports of entry and delivery have been multiplied and established, not only upon our sea-board but in the interior of the country upon our lakes and navigable rivers. The convenience and safety of this commerce have led to the gradual extension of these expenditures; to the erection of light houses, the placing, planting, and sinking of buoys, beacons, and piers, and to the removal of partial and temporary obstructions in our navigable rivers and in the harbors upon our Great Lakes as well as on the sea-board.

Although I have expressed to Congress my apprehension that these expenditures have some times been extravagant and disproportionate to the advantages to be derived from them, I have not felt it to be my duty to refuse my assent to bills containing them, and have contented myself to follow in this respect in the foot-steps of all my predecessors. Sensible, however, from experience and observation of the great abuses to which the unrestricted exercise of this authority by Congress was exposed, I have prescribed a limitation for the government of my own conduct by which expenditures of this character are confined to places below the ports of entry or delivery established by law. I am very sensible that this restriction is not as satisfactory as could be desired, and that much embarrassment may be caused to the executive department in its execution by appropriations for remote and not well-understood objects. But as neither my own reflections nor the lights which I may properly derive from other sources have supplied me with a better, I shall continue to apply my best exertions to a faithful application of the rule upon which it is founded.

I sincerely regret that I could not give my assent to the bill entitled: "An act to improve the navigation of the Wabash River"; but I could not have done so without receding from the ground which I have, upon the fullest consideration, taken upon this subject, and of which Congress has been heretofore apprised, and without throwing the subject again open to abuses which no good citizen entertaining my opinions could desire.

I rely upon the intelligence and candor of my fellow citizens, in whose liberal indulgence I have already so largely participated, for a correct appreciation on my motives in interposing as I have done on this and other occasions checks to a course of legislation which, without in the slightest degree calling in question the motives of others, I consider as sanctioning improper and unconstitutional expenditures of public treasure.
