Without desiring to conceal that the experience and observation of the last two years have operated a partial change in my views upon this interesting subject, it is never the less regretted that the suggestions made by me in my annual messages of 1829 and 1830 have been greatly misunderstood. At that time the great struggle was begun against that latitudinarian construction of the Constitution which authorizes the unlimited appropriation of the revenues of the Union to internal improvements within the States, tending to invest in the hands and place under the control of the General Government all the principal roads and canals of the country, in violation of State rights and in derogation of State authority. At the same time the condition of the manufacturing interest was such as to create an apprehension that the duties on imports could not without extensive mischief be reduced in season to prevent the accumulation of a considerable surplus after the payment of the national debt. In view of the dangers of such a surplus, and in preference to its application to internal improvements in derogation of the rights and powers of the States, the suggestion of an amendment of the Constitution to authorize its distribution was made. It was an alternative for what were deemed greater evils--a temporary resort to relieve an over-burdened treasury until the Government could, without a sudden and destructive revulsion in the business of the country, gradually return to the just principle of raising no more revenue from the people in taxes than is necessary for its economical support. Even that alternative was not spoken of but in connection with an amendment of the Constitution. No temporary inconvenience can justify the exercise of a prohibited power not granted by that instrument, and it was from a conviction that the power to distribute even a temporary surplus of revenue is of that character that it was suggested only in connection with an appeal to the source of all legal power in the General Government, the States which have established it. No such appeal has been taken, and in my opinion a distribution of the surplus revenue by Congress either to the States or the people is to be considered as among the prohibitions of the Constitution. As already intimated, my views have undergone a change so far as to be convinced that no alteration of the Constitution in this respect is wise or expedient. The influence of an accumulating surplus upon the credit system of the country, producing dangerous extensions and ruinous contractions, fluctuations in the price of property, rash speculation, idleness, extravagance, and a deterioration of morals, have taught us the important lesson that any transient mischief which may attend the reduction of our revenue to the wants of our Government is to be borne in preference to an over-flowing treasury.
