The surveys before alluded to were designed to ascertain the most practicable and economical route for a railroad from the river Mississippi to the Pacific Ocean. Parties are now in the field making explorations, where previous examinations had not supplied sufficient data and where there was the best reason to hope the object sought might be found. The means and time being both limited, it is not to be expected that all the accurate knowledge desired will be obtained, but it is hoped that much and important information will be added to the stock previously possessed, and that partial, if not full, reports of the surveys ordered will be received in time for transmission to the two Houses of Congress on or before the first Monday in February next, as required by the act of appropriation. The magnitude of the enterprise contemplated has aroused and will doubtless continue to excite a very general interest throughout the country. In its political, its commercial, and its military bearings it has varied, great, and increasing claims to consideration. The heavy expense, the great delay, and, at times, fatality attending travel by either of the Isthmus routes have demonstrated the advantage which would result from interterritorial communication by such safe and rapid means as a railroad would supply.
These difficulties, which have been encountered in a period of peace, would be magnified and still further increased in time of war. But whilst the embarrassments already encountered and others under new contingencies to be anticipated may serve strikingly to exhibit the importance of such a work, neither these nor all considerations combined can have an appreciable value when weighed against the obligation strictly to adhere to the Constitution and faithfully to execute the powers it confers.
Within this limit and to the extent of the interest of the Government involved it would seem both expedient and proper if an economical and practicable route shall be found to aid by all constitutional means in the construction of a road which will unite by speedy transit the populations of the Pacific and Atlantic States. To guard against misconception, it should be remarked that although the power to construct or aid in the construction of a road within the limits of a Territory is not embarrassed by that question of jurisdiction which would arise within the limits of a State, it is, nevertheless, held to be of doubtful power and more than doubtful propriety, even within the limits of a Territory, for the General Government to undertake to administer the affairs of a railroad, a canal, or other similar construction, and therefore that its connection with a work of this character should be incidental rather than primary. I will only add at present that, fully appreciating the magnitude of the subject and solicitous that the Atlantic and Pacific shores of the Republic may be bound together by inseparable ties of common interest, as well as of common fealty and attachment to the Union, I shall be disposed, so far as my own action is concerned, to follow the lights of the Constitution as expounded and illustrated by those whose opinions and expositions constitute the standard of my political faith in regard to the powers of the Federal Government. It is, I trust, not necessary to say that no grandeur of enterprise and no present urgent inducement promising popular favor will lead me to disregard those lights or to depart from that path which experience has proved to be safe, and which is now radiant with the glow of prosperity and legitimate constitutional progress. We can afford to wait, but we can not afford to overlook the ark of our security.
It is no part of my purpose to give prominence to any subject which may properly be regarded as set at rest by the deliberate judgment of the people. But while the present is bright with promise and the future full of demand and inducement for the exercise of active intelligence, the past can never be without useful lessons of admonition and instruction. If its dangers serve not as beacons, they will evidently fail to fulfill the object of a wise design. When the grave shall have closed over all who are now endeavoring to meet the obligations of duty, the year 1850 will be recurred to as a period filled with anxious apprehension. A successful war had just terminated. Peace brought with it a vast augmentation of territory. Disturbing questions arose bearing upon the domestic institutions of one portion of the Confederacy and involving the constitutional rights of the States. But notwithstanding differences of opinion and sentiment which then existed in relation to details and specific provisions, the acquiescence of distinguished citizens, whose devotion to the Union can never be doubted, has given renewed vigor to our institutions and restored a sense of repose and security to the public mind throughout the Confederacy. That this repose is to suffer no shock during my official term, if I have power to avert it, those who placed me here may be assured. The wisdom of men who knew what independence cost, who had put all at stake upon the issue of the Revolutionary struggle, disposed of the subject to which I refer in the only way consistent with the Union of these States and with the march of power and prosperity which has made us what we are. It is a significant fact that from the adoption of the Constitution until the officers and soldiers of the Revolution had passed to their graves, or, through the infirmities of age and wounds, had ceased to participate actively in public affairs, there was not merely a quiet acquiescence in, but a prompt vindication of, the constitutional rights of the States. The reserved powers were scrupulously respected. No statesman put forth the narrow views of casuists to justify interference and agitation, but the spirit of the compact was regarded as sacred in the eye of honor and indispensable for the great experiment of civil liberty, which, environed by inherent difficulties, was yet borne forward in apparent weakness by a power superior to all obstacles. There is no condemnation which the voice of freedom will not pronounce upon us should we prove faithless to this great trust. While men inhabiting different parts of this vast continent can no more be expected to hold the same opinions or entertain the same sentiments than every variety of climate or soil can be expected to furnish the same agricultural products, they can unite in a common object and sustain common principles essential to the maintenance of that object. The gallant men of the South and the North could stand together during the struggle of the Revolution; they could stand together in the more trying period which succeeded the clangor of arms. As their united valor was adequate to all the trials of the camp and dangers of the field, so their united wisdom proved equal to the greater task of founding upon a deep and broad basis institutions which it has been our privilege to enjoy and will ever be our most sacred duty to sustain. It is but the feeble expression of a faith strong and universal to say that their sons, whose blood mingled so often upon the same field during the War of 1812 and who have more recently borne in triumph the flag of the country upon a foreign soil, will never permit alienation of feeling to weaken the power of their united efforts nor internal dissensions to paralyze the great arm of freedom, uplifted for the vindication of self-government.
I have thus briefly presented such suggestions as seem to me especially worthy of your consideration. In providing for the present you can hardly fail to avail yourselves of the light which the experience of the past casts upon the future.
The growth of our population has now brought us, in the destined career of our national history, to a point at which it well behooves us to expand our vision over the vast prospective.
The successive decennial returns of the census since the adoption of the Constitution have revealed a law of steady, progressive development, which may be stated in general terms as a duplication every quarter century. Carried forward from the point already reached for only a short period of time, as applicable to the existence of a nation, this law of progress, if unchecked, will bring us to almost incredible results. A large allowance for a diminished proportional effect of emigration would not very materially reduce the estimate, while the increased average duration of human life known to have already resulted from the scientific and hygienic improvements of the past fifty years will tend to keep up through the next fifty, or perhaps hundred, the same ratio of growth which has been thus revealed in our past progress; and to the influence of these causes may be added the influx of laboring masses from eastern Asia to the Pacific side of our possessions, together with the probable accession of the populations already existing in other parts of our hemisphere, which within the period in question will feel with yearly increasing force the natural attraction of so vast, powerful, and prosperous a confederation of self-governing republics and will seek the privilege of being admitted within its safe and happy bosom, transferring with themselves, by a peaceful and healthy process of incorporation, spacious regions of virgin and exuberant soil, which are destined to swarm with the fast-growing and fast-spreading millions of our race.
These considerations seem fully to justify the presumption that the law of population above stated will continue to act with undiminished effect through at least the next half century, and that thousands of persons who have already arrived at maturity and are now exercising the rights of freemen will close their eyes on the spectacle of more than 100,000,000 of population embraced within the majestic proportions of the American Union. It is not merely as an interesting topic of speculation that I present these views for your consideration. They have important practical bearings upon all the political duties we are called upon to perform. Heretofore our system of government has worked on what may be termed a miniature scale in comparison with the development which it must thus assume within a future so near at hand as scarcely to be beyond the present of the existing generation.
It is evident that a confederation so vast and so varied, both in numbers and in territorial extent, in habits and in interests, could only be kept in national cohesion by the strictest fidelity to the principles of the Constitution as understood by those who have adhered to the most restricted construction of the powers granted by the people and the States. Interpreted and applied according to those principles, the great compact adapts itself with healthy ease and freedom to an unlimited extension of that benign system of federative self-government of which it is our glorious and, I trust, immortal charter. Let us, then, with redoubled vigilance, be on our guard against yielding to the temptation of the exercise of doubtful powers, even under the pressure of the motives of conceded temporary advantage and apparent temporary expediency.
The minimum of Federal government compatible with the maintenance of national unity and efficient action in our relations with the rest of the world should afford the rule and measure of construction of our powers under the general clauses of the Constitution. A spirit of strict deference to the sovereign rights and dignity of every State, rather than a disposition to subordinate the States into a provincial relation to the central authority, should characterize all our exercise of the respective powers temporarily vested in us as a sacred trust from the generous confidence of our constituents.
