Sincerely friendly to the improvement of our country by means of roads and canals, I regret that any difference of opinion in the mode of contributing to it should exist between us; and if in stating this difference I go beyond what the occasion may be deemed to call for, I hope to find an apology in the great importance of the subject, an unfeigned respect for the high source from which this branch of it has emanated, and an anxious wish to be correctly understood by my constituents in the discharge of all my duties.  Diversity of sentiment among public functionaries actuated by the same general motives, on the character and tendency of particular measures, is an incident common to all Governments, and the more to be expected in one which, like ours, owes its existence to the freedom of opinion, and must be upheld by the same influence.  Controlled as we thus are by a higher tribunal, before which our respective acts will be canvassed with the indulgence due to the imperfections of our nature, and with that intelligence and unbiased judgment which are the true correctives of error, all that our responsibility demands is that the public good should be the measure of our views, dictating alike their frank expression and honest maintenance.

In the message which was presented to Congress at the opening of its present session I endeavored to exhibit briefly my views upon the important and highly interesting subject to which our attention is now to be directed.  I was desirous of presenting to the representatives of the several States in Congress assembled the inquiry whether some mode could not be devised which would reconcile the diversity of opinion concerning the powers of this Government over the subject of internal improvement, and the manner in which these powers, if conferred by the Constitution, ought to be exercised.  The act which I am called upon to consider has, therefore, been passed with a knowledge of my views on this question, as these are expressed in the message referred to.  In that document the following suggestions will be found: 

After the extinction of the public debt it is not probable that any adjustment of the tariff upon principles satisfactory to the people of the Union will until a remote period, if ever, leave the Government without a considerable surplus in the Treasury beyond what may be required for its current service.  As, then, the period approaches when the application of the revenue to the payment of debt will cease, the disposition of the surplus will present a subject for the serious deliberation of Congress; and it may be fortunate for the country that it is yet to be decided.  Considered in connection with the difficulties which have heretofore attended appropriations for purposes of internal improvement, and with those which this experience tells us will certainly arise whenever power over such subjects may be exercised by the General Government, it is hoped that it may lead to the adoption of
