In this brief outline of the promise and performance of my immediate predecessor the line of duty for his successor is clearly delineated. To pursue to their consummation those purposes of improvement in our common condition instituted or recommended by him will embrace the whole sphere of my obligations. To the topic of internal improvement, emphatically urged by him at his inauguration, I recur with peculiar satisfaction. It is that from which I am convinced that the unborn millions of our posterity who are in future ages to people this continent will derive their most fervent gratitude to the founders of the Union; that in which the beneficent action of its Government will be most deeply felt and acknowledged. The magnificence and splendor of their public works are among the imperishable glories of the ancient republics. The roads and aqueducts of Rome have been the admiration of all after ages, and have survived thousands of years after all her conquests have been swallowed up in despotism or become the spoil of barbarians. Some diversity of opinion has prevailed with regard to the powers of Congress for legislation upon objects of this nature. The most respectful deference is due to doubts originating in pure patriotism and sustained by venerated authority. But nearly twenty years have passed since the construction of the first national road was commenced. The authority for its construction was then unquestioned. To how many thousands of our countrymen has it proved a benefit? To what single individual has it ever proved an injury? Repeated, liberal, and candid discussions in the Legislature have conciliated the sentiments and approximated the opinions of enlightened minds upon the question of constitutional power. I can not but hope that by the same process of friendly, patient, and persevering deliberation all constitutional objections will ultimately be removed. The extent and limitation of the powers of the General Government in relation to this transcendently important interest will be settled and acknowledged to the common satisfaction of all, and every speculative scruple will be solved by a practical public blessing.
