The late Confederacy, by imposing an export duty of twenty cents per pound, to be paid in gold; France, by her export duty on linen and cotton rags and skins of animals; Russia, by various export duties; Portugal, by her duties on wine exported; Great Britain, by her export duties, imposed in India, on gunny-cloth, linseed, jute, saltpetre, and opium; and Holland, by her monopoly and export duties on the coffee of Java,--give precedents for a tax on cotton. The United States are prohibited by the Constitution from levying an export duty, but may nevertheless impose an internal tax which will cling to the cotton both abroad and at home. A tax of five cents a pound will add but one cent to the cost of a yard of calico; and with a crop of 2,000,000,000 pounds, like that of 1859, will yield a revenue of $100,000,000, although the Commission do not anticipate more than half that revenue for a few years to come. It seems but reasonable that King Cotton, who made the war, should aid in defraying its expenses; and it is also just that England and France, his chief allies, should pay their tribute for the suppression of the revolt they did so much to encourage. The planters and free blacks of the South have sufficient incentives to the culture of cotton in the high prices it must bear for years to come; and the Commission have very wisely recommended a remission of the tax on all cotton cloth or yarn exported, which will give a stimulus to manufactures both at the South and the North, and enable our merchants to meet those of Great Britain in successful competition in all parts of the globe. The cotton tax, as a substitute for taxes on sales and manufactures, will meet the cordial support of our countrymen; and, if it oppose a slight check to production, they have already learned that half a crop gives more dollars than a whole one.
