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.

By an act of Congress of March 3d, 1825, a loan for the purpose now referred to, or a subscription to stock, was authorized, at an interest not exceeding 4.5%.  But at that time so large a portion of the floating capital of the country was absorbed in commercial speculations and so little was left for investment in the stocks that the measure was but partially successful.  At the last session of Congress the condition of the funds was still unpropitious to the measure; but the change so soon afterwards occurred that, had the authority existed to redeem the $9 millions now redeemable by an exchange of stocks or a loan at 5%, it is morally certain that it might have been effected, and with it a yearly saving of $90,000.

With regard to the collection of the revenue of imposts, certain occurrences have within the last year been disclosed in one or two of our principal ports, which engaged the attention of Congress at their last session and may hereafter require further consideration.  Until within a very few years the execution of the laws for raising the revenue, like that of all our other laws, has been insured more by the moral sense
