The actual receipts into the Treasury, arising from that source of revenue, were in round numbers for the years 1812, 1813, 1814, respectively 8,960,000, 13,225,000, and 6,000,000 of dollars; and the nett revenue which accrued during those three years respectively amounted to 13,142,000, 6,708,000, and 4,250,000 dollars. From the 1st of July, 1812, the rate of duties on importations was doubled; and in order to compare these receipts with those collected in peace time, they must be reduced for those three years respectively, to 7,470,000,[3] 6,600,000 and 3,000,000; or, if the revenue accrued be compared (which is the correct mode), to 9,850,000,[3] 3,354,000, and 2,125,000 dollars. At that time the duties accrued were, on account of the credit allowed, collected on an average only six or eight months later; and the unexpected importations in the latter half of the year 1812 in American vessels which arrived with British licenses, subsequent to the declaration of war and to the act which doubled the rate of duties, swelled considerably the receipts of the year 1813. It was only in 1814 that the full effect of the war on the revenue derived from that source was felt. The diminution in the amount of American and foreign tonnage employed in the foreign trade of the United States is strongly exhibited by the following statement: Tonnage in foreign trade, U. S. American ves. Foreign ves. Total. Year 1811 948,207 33,203 981,450 " 1812 667,999 47,099 715,098 " 1813 237,348 113,827 351,175 " 1814 59,626 48,302 107,928 And it must be recollected that during the last nine months of 1814, Great Britain was at peace with all the other Powers of Europe, and that these were therefore neutrals. Yet they hardly ventured to trade with us. The amount of receipts into the Treasury derived from customs, as well as that of the revenue accrued, exceeded, during the eleven years 1801 to 1811, 132,700,000 dollars, being an annual average of about 12,000,000 dollars. During the same eleven years the average amount of tonnage employed in the foreign trade of the United States was 943,670 tons, of which 844,170 were in American, and 99,500 foreign vessels. Thus in the year 1814, the revenue derived from customs had been reduced to one fourth part (to nearly one sixth part, if compared according to the revenue accrued, or amount of importations), the tonnage employed in the foreign trade of the United States to nearly one ninth; and that of the American vessels employed in that trade, to one fourteenth part of their respective average amount during the eleven years of peace.
