I think that I may venture to affirm that there is no part of our globe comprehending so many degrees of latitude on the main ocean and so many degrees of longitude into the interior that admits of such great improvement and at so little expense. The Atlantic on the one side, and the Lakes, forming almost inland seas, on the other, separated by high mountains, which rise in the valley of the St. Lawrence and determine in that of the Mississippi, traversing from north to south almost the whole interior, with innumerable rivers on every side of those mountains, some of vast extent, many of which take their sources near to each other, give the great outline. The details are to be seen on the valuable maps of our country.
It appears by the light already before the public that it is practicable and easy to connect by canals the whole coast from its southern to its northern extremity in one continued inland navigation, and to connect in like manner in many parts the Western lakes and rivers with each other. It is equally practicable and easy to facilitate the intercourse between the Atlantic and the Western country by improving the navigation of many of the rivers which have their sources near to each other in the mountains on each side, and by good roads across the mountains between the highest navigable points of those rivers. In addition to the example of the Cumberland road, already noticed, another of this kind is now in train from the head waters of the river James to those of the Kanawha; and in like manner may the Savannah be connected with the Tennessee. In some instances it is understood that the Eastern and Western waters may be connected together directly by canals. One great work of this kind is now in its progress and far advanced in the State of New York, and there is good reason to believe that two others may be formed, one at each extremity of the high mountains above mentioned, connecting in the one instance the waters of the St. Lawrence with Lake Champlain, and in the other some of the most important of the Western rivers with those emptying into the Gulf of Mexico, the advantage of which will be seen at the first glance by an enlightened observer.
Great improvements may also be made by good roads in proper directions through the interior of the country. As these roads would be laid out on principle on a full view of the country, its mountains, rivers, etc., it would be useless, if I had the knowledge, to go into detail respecting them. Much has been done by some of the States, but yet much remains to be done with a view to the Union.
Under the colonial governments improvements of this kind were not thought of. There was, it is believed, not one canal and little communication from colony to colony. It was their policy to encourage the intercourse between each colony and the parent country only. The roads which were attended to were those which led from the interior of each colony to its principal towns on the navigable waters. By those routes the produce of the country was carried to the coast, and shipped thence to the mercantile houses in London, Liverpool, Glasgow, or other towns to which the trade was carried on. It is believed that there was but one connected route from North to South at the commencement of the Revolution, and that a very imperfect one. The existence and principle of our Union point out the necessity of a very different policy.
The advantages which would be derived from such improvements are incalculable. The facility which would thereby be afforded to the transportation of the whole of the rich productions of our country to market would alone more than amply compensate for all the labor and expense attending them. Great, however, as is that advantage, it is one only of many and by no means the most important, Every power of the General Government and of the State governments connected with the strength and resources of the country would be made more efficient for the purposes intended by them. In war they would facilitate the transportation of men, ordnance, and provisions, and munitions of war of every kind to every part of our extensive coast and interior on which an attack might be made or threatened. Those who have any knowledge of the occurrences of the late war must know the good effect which would result in the event of another war from the command of an interior navigation alone along the coast for all the purposes of war as well as of commerce between the different parts of our Union. The impediments to all military operations which proceeded from the want of such a navigation and the reliance which was placed, notwithstanding those impediments, on such a commerce can not be forgotten. In every other line their good effect would be most sensibly felt. Intelligence by means of the Post-Office Department would be more easily, extensively, and rapidly diffused. Parts the most remote from each other would be brought more closely together. Distant lands would be made more valuable, and the industry of our fellow-citizens on every portion of our soil be better rewarded.
It is natural in so great a variety of climate that there should be a corresponding difference in the produce of the soil; that one part should raise what the other might want. It is equally natural that the pursuits of industry should vary in like manner; that labor should be cheaper and manufactures succeed better in one part than in another; that were the climate the most severe and the soil less productive, navigation, the fisheries, and commerce should be most relied on. Hence the motive for an exchange for mutual accommodation and active intercourse between them. Each part would thus find for the surplus of its labor, in whatever article it consisted, an extensive market at home, which would be the most profitable because free from duty.
There is another view in which these improvements are of still more vital importance. The effect which they would have on the bond of union itself affords an inducement for them more powerful than any which have been urged or than all of them united. The only danger to which our system is exposed arises from its expansion over a vast territory. Our union is not held together by standing armies or by any ties other than the positive interests and powerful attractions of its parts toward each other. Ambitious men may hereafter grow up among us who may promise to themselves advancement from a change, and by practicing upon the sectional interests, feelings, and prejudices endeavor under various pretexts to promote it. The history of the world is replete with examples of this kind—of military commanders and demagogues becoming usurpers and tyrants, and of their fellow-citizens becoming their instruments and slaves. I have little fear of this danger, knowing well how strong the bond which holds us together is and who the people are who are thus held together; but still, it is proper to look at and to provide against it, and it is not within the compass of human wisdom to make a more effectual provision than would be made by the proposed improvements. With their aid and the intercourse which would grow out of them the parts would soon become so compacted and bound together that nothing could break it.
The expansion of our Union over a vast territory can not operate unfavorably to the States individually. On the contrary, it is believed that the greater the expansion within practicable limits—and it is not easy to say what are not so—the greater the advantage which the States individually will derive from it. With governments separate, vigorous, and efficient for all local purposes, their distance from each other can have no injurious effect upon their respective interests. It has already been shown that in some important circumstances, especially with the aid of these improvements, they must derive great advantage from that cause alone—that is, from their distance from each other. In every other way the expansion of our system must operate favorably for every State in proportion as it operates favorably for the Union. It is in that sense only that it can become a question with the States, or, rather, with the people who compose them. As States they can be affected by it only by their relation to each other through the General Government and by its effect on the operations of that Government. Manifest it is that to any extent to which the General Government can sustain and execute its functions with complete effect will the States—that is, the people who compose them—be benefited. It is only when the expansion shall be carried beyond the faculties of the General Government so as to enfeeble its operations to the injury of the whole that any of the parts can be injured. The tendency in that stage will be to dismemberment and not to consolidation. This danger should, therefore, be looked at with profound attention as one of a very serious character. I will remark here that as the operations of the National Government are of a general nature, the States having complete power for internal and local purposes, the expansion may be carried to very great extent and with perfect safety. It must be obvious to all that the further the expansion is carried, provided it be not beyond the just limit, the greater will be the freedom of action to both Governments and the more perfect their security, and in all other respects the better the effect will be to the whole American people. Extent of territory, whether it be great or small, gives to a nation many of its characteristics. It marks the extent of its resources, of its population, of its physical force. It marks, in short, the difference between a great and a small power.
To what extent it may be proper to expand our system of government is a question which does not press for a decision at this time. At the end of the Revolutionary war, in 1783, we had, as we contended and believed, a right to the free navigation of the Mississippi, but it was not until after the expiration of twelve years, in 1795, that that right was acknowledged and enjoyed. Further difficulties occurred in the bustling of a contentious world when, at the expiration of eight years more, the United States, sustaining the strength and energy of their character, acquired the Province of Louisiana, with the free navigation of the river from its source to the ocean and a liberal boundary on the western side. To this Florida has since been added, so that we now possess all the territory in which the original States had any interest, or in which the existing States can be said, either in a national or local point of view, to be in any way interested. A range of States on the western side of the Mississippi, which already is provided for, puts us essentially at ease. Whether it will be wise to go further will turn on other considerations than those which have dictated the course heretofore pursued. At whatever point we may stop, whether it be at a single range of States beyond the Mississippi or by taking a greater scope, the advantage of such improvements is deemed of the highest importance. It is so on the present scale. The further we go the greater will be the necessity for them.
It can not be doubted that improvements for great national purposes would be better made by the National Government than by the governments of the several States. Our experience prior to the adoption of the Constitution demonstrated that in the exercise by the individual States of most of the powers granted to the United States a contracted rivalry of interest and misapplied jealousy of each other had an important influence on all their measures to the great injury of the whole. This was particularly exemplified by the regulations which they severally made of their commerce with foreign nations and with each other. It was this utter incapacity in the State governments, proceeding from these and other causes, to act as a nation and to perform all the duties which the nation owed to itself under any system which left the General Government dependent on the States, which produced the transfer of these powers to the United States by the establishment of the present Constitution. The reasoning which was applicable to the grant of any of the powers now vested in Congress is likewise so, at least to a certain extent, to that in question. It is natural that the States individually in making improvements should look to their particular and local interests, The members composing their respective legislatures represent the people of each State only, and might not feel themselves at liberty to look to objects in these respects beyond that limit. If the resources of the Union were to be brought into operation under the direction of the State assemblies, or in concert with them, it may be apprehended that every measure would become the object of negotiation, of bargain and barter, much to the disadvantage of the system, as well as discredit to both governments. But Congress would look to the whole and make improvements to promote the welfare of the whole. It is the peculiar felicity of the proposed amendment that while it will enable the United States to accomplish every national object, the improvements made with that view will eminently promote the welfare of the individual States, who may also add such others as their own particular interests may require.
