Great capitalists will derive the benefit incident to their superior wealth under any mode of sale which may be adopted, but if, looking forward to the rise in the value of the public lands, they should have the opportunity of amassing at a low price vast bodies in their hands, the profit will accrue to them and not to the public. They would also have the power in that degree to control the emigration and settlement in such a manner as their opinion of their respective interests might dictate. I submit this subject to the consideration of Congress, that such further provision may be made in the sale of the public lands, with a view to the public interest, should any be deemed expedient, as in their judgment may be best adapted to the object. When we consider the vast extent of territory within the United States, the great amount and value of its productions, the connection of its parts, and other circumstances on which their prosperity and happiness depend, we can not fail to entertain a high sense of the advantage to be derived from the facility which may be afforded in the intercourse between them by means of good roads and canals. Never did a country of such vast extent offer equal inducements to improvements of this kind, nor ever were consequences of such magnitude involved in them. As this subject was acted on by Congress at the last session, and there may be a disposition to revive it at the present, I have brought it into view for the purpose of communicating my sentiments on a very important circumstance connected with it with that freedom and candor which a regard for the public interest and a proper respect for Congress require. A difference of opinion has existed from the first formation of our Constitution to the present time among our most enlightened and virtuous citizens respecting the right of Congress to establish such a system of improvement. Taking into view the trust with which I am now honored, it would be improper after what has passed that this discussion should be revived with an uncertainty of my opinion respecting the right. Disregarding early impressions I have bestowed on the subject all the deliberation which its great importance and a just sense of my duty required, and the result is a settled conviction in my mind that Congress do not possess the right. It is not contained in any of the specified powers granted to Congress, nor can I consider it incidental to or a necessary means, viewed on the most liberal scale, for carrying into effect any of the powers which are specifically granted.
