Plain as these principles appear to be, you will yet find there is a constant effort to induce the General Government to go beyond the limits of its taxing power and to impose unnecessary burdens upon the people. Many powerful interests are continually at work to procure heavy duties on commerce and to swell the revenue beyond the real necessities of the public service, and the country has already felt the injurious effects of their combined influence. They succeeded in obtaining a tariff of duties bearing most oppressively on the agricultural and laboring classes of society and producing a revenue that could not be usefully employed within the range of the powers conferred upon Congress, and in order to fasten upon the people this unjust and unequal system of taxation extravagant schemes of internal improvement were got up in various quarters to squander the money and to purchase support. Thus one unconstitutional measure was intended to be upheld by another, and the abuse of the power of taxation was to be maintained by usurping the power of expending the money in internal improvements. You can not have forgotten the severe and doubtful struggle through which we passed when the executive department of the Government by its veto endeavored to arrest this prodigal scheme of injustice and to bring back the legislation of Congress to the boundaries prescribed by the Constitution. The good sense and practical judgment of the people when the subject was brought before them sustained the course of the Executive, and this plan of unconstitutional expenditures for the purposes of corrupt influence is, I trust, finally overthrown.
The result of this decision has been felt in the rapid extinguishment of the public debt and the large accumulation of a surplus in the Treasury, notwithstanding the tariff was reduced and is now very far below the amount originally contemplated by its advocates. But, rely upon it, the design to collect an extravagant revenue and to burden you with taxes beyond the economical wants of the Government is not yet abandoned. The various interests which have combined together to impose a heavy tariff and to produce an overflowing Treasury are too strong and have too much at stake to surrender the contest. The corporations and wealthy individuals who are engaged in large manufacturing establishments desire a high tariff to increase their gains. Designing politicians will support it to conciliate their favor and to obtain the means of profuse expenditure for the purpose of purchasing influence in other quarters; and since the people have decided that the Federal Government can not be permitted to employ its income in internal improvements, efforts will be made to seduce and mislead the citizens of the several States by holding out to them the deceitful prospect of benefits to be derived from a surplus revenue collected by the General Government and annually divided among the States; and if, encouraged by these
