By Treasury Table 24, our total exports abroad of domestic produce, exclusive of specie, from the 30th of September, 1821, to 30th June, 1861, were $5,060,929,667; and, in the year ending the 30th June, 1860, were $316,242,423. At the same rate of increase from 1860 to 1870, as from 1850 to 1860, our domestic exports exclusive of specie in the decade ending the 30th June, 1870, would have exceeded five billions of dollars, had peace continued and the currency been no more redundant in proportion to our wealth than in 1860. But with a redundant and depreciated currency our exports must have been reduced at least one fourth. What would be the effect on every branch of our industry, may be learned by looking at Treasury Table 40, showing our domestic exports for the year ending 30th June, 1861. These exports were, of the products of our fisheries, $4,451,515; of the forest, $10,260,809; of agriculture, exclusive of cotton, rice, and tobacco, $100,273,655, and of our manufactures, $35,786,804. This was mainly from the loyal States. Now if the foreign markets for our products are reduced only one fourth by the effect of a redundant currency, inflating here the cost of production and of living, the result would be most disastrous to our industry. The reduction would be equal, as we have seen, to $125,000,000 per annum, and $1,250,000,000 in the decade. Our imports would be reduced in the same proportion, and our revenue from customs in a corresponding ratio. Supposing the average rate of duties of the present tariff to be equal to 40 per cent. ad valorem, this would make a difference in our revenue from customs of $500,000,000 in the decade, and, including interest not compounded, $635,000,000. And here I deem it a duty to say to the financial portion of our peace party, especially in New York, that our redundant and depreciated currency, with our failure to crush the rebellion, and a consequent dissolution of the Union, would make repudiation inevitable. We are forced, then, by a due regard to our material interests, as well as by the higher obligations of honor and duty, to subdue the revolt and restore the supremacy of the Government in every State. This we can and must do. It is due to our country and to the world. It is due to the wounded and mutilated survivors of the bloody conflict, and to our martyred dead, murdered by the foulest treason, and in the accursed cause of slavery. No! all this blood and treasure must not have been poured out in vain. It is a question mainly of money and persistence. Our armies can and will conquer the rebellion, if we can and will supply the sinews of war. Our success is much more a financial than a military question. As regards the result, the Secretary of the Treasury holds now the most important post in this contest: he is the generalissimo; and as he is right on this question, and the fate of the Union is involved, I deem it my duty to give him my earnest and zealous support.
