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.
