The expenditures for the same period, including the necessary payment on account of the principal and interest of the public debt, and the principal and interest of the first installment due to Mexico on the 30th of May next, and other expenditures growing out of the war to be paid during the present year, will amount, including the reimbursement of Treasury notes, to the sum of $54,195,275.06, leaving an estimated balance in the Treasury on the 1st of July, 1849, of $2,853,694.84. The Secretary of the Treasury will present, as required by law, the estimate of the receipts and expenditures for the next fiscal year. The expenditures as estimated for that year are $33,213,152.73, including $3,799,102.18 for the interest on the public debt and $3,540,000 for the principal and interest due to Mexico on the 30th of May, 1850, leaving the sum of $25,874,050.35, which, it is believed, will be ample for the ordinary peace expenditures. The operations of the tariff act of 1846 have been such during the past year as fully to meet the public expectation and to confirm the opinion heretofore expressed of the wisdom of the change in our revenue system which was effected by it. The receipts under it into the Treasury for the first fiscal year after its enactment exceeded by the sum of $5,044,403.09 the amount collected during the last fiscal year under the tariff act of 1842, ending the 30th of June, 1846. The total revenue realized from the commencement of its operation, on the 1st of December, 1846, until the close of the last quarter, on the 30th of September last, being twenty-two months, was $56,654,563.79, being a much larger sum than was ever before received from duties during any equal period under the tariff acts of 1824, 1828, 1832, and 1842. Whilst by the repeal of highly protective and prohibitory duties the revenue has been increased, the taxes on the people have been diminished. They have been relieved from the heavy amounts with which they were burthened under former laws in the form of increased prices or bounties paid to favored classes and pursuits. The predictions which were made that the tariff act of 1846 would reduce the amount of revenue below that collected under the act of 1842, and would prostrate the business and destroy the prosperity of the country, have not been verified. With an increased and increasing revenue, the finances are in a highly flourishing condition. Agriculture, commerce, and navigation are prosperous; the prices of manufactured fabrics and of other products are much less injuriously affected than was to have been anticipated from the unprecedented revulsions which during the last and the present year have overwhelmed the industry and paralyzed the credit and commerce of so many great and enlightened nations of Europe.
