A Biography of Henry Clay, the Senator from Kentucky
“ The framers of our constitution, by granting the power to congress to lay imports, and prohibiting that of laying an export duty, manifested that they did not regard them as equivalent. Nor does the common sense of mankind. An export duty fastens upon, and incorporates itself with, the article on which it is laid. The article cannot escape from it—it pursues and follows it, wherever the article goes; and if, in the foreign market, the supply is above or just equal to the demand, the amount of the export duty will be a clear deduction to the exporter from the price of the article. ”
