Yet our experience has proved that a revenue consisting so largely of imposts and tonnage ebbs and flows to an extraordinary extent, with all the fluctuations incident to the general commerce of the world. It is within our recollection that even in the compass of the same last ten years the receipts of the Treasury were not adequate to the expenditures of the year, and that in two successive years it was found necessary to resort to loans to meet the engagements of the nation. The returning tides of the succeeding years replenished the public coffers until they have again begun to feel the vicissitude of a decline. To produce these alternations of fullness and exhaustion the relative operation of abundant or unfruitful seasons, the regulations of foreign governments, political revolutions, the prosperous or decaying condition of manufactures, commercial speculations, and many other causes, not always to be traced, variously combine. We have found the alternate swells and diminutions embracing periods of from two to three years. The last period of depression to United States was from 1819 to 1822. The corresponding revival was from 1823 to the commencement of the present year. Still, we have no cause to apprehend a depression comparable to that of the former period, or even to anticipate a deficiency which will intrench upon the ability to apply the annual $10 millions to the reduction of the debt. It is well for us, however, to be admonished of the necessity of abiding by the maxims of the most vigilant economy, and of resorting to all honorable and useful expedients for pursuing with steady and inflexible perseverance the total discharge of the debt. Besides the $7,000,000 of the loans of 1813 which will have been discharged in the course of the present year, there are $9,000,000 which by the terms of the contracts would have been and are now redeemable. $13,000,000 more of the loan of 1814 will become redeemable from and after the expiration of the present month, and $9,000,000 other from and after the close of the ensuing year. They constitute a mass of $31,000,000, all bearing an interest of 6%, more than $20,000,000 of which will be immediately redeemable, and the rest within little more than a year. Leaving of this amount $15,000,000 to continue at the interest of 6%, but to be paid off as far as shall be found practicable in the years 1827 and 1828, there is scarcely a doubt that the remaining $16,000,000 might within a few months be discharged by a loan at not exceeding 5%, redeemable in the years 1829 and 1830. By this operation a sum of nearly $500,000 may be saved to the nation, and the discharge of the whole $31,000,000 within the four years may be greatly facilitated if not wholly accomplished.
