These duties would not be imposed upon any imports into our own country, but only upon imports into Mexico, and the tax would fall upon the people of Mexico in the enhancement to them of the prices of these imports.  Nearly all our own products are excluded by the Mexican tariff even in time of peace; they are excluded also during the war so far as we continue the system of blockading any of the ports of Mexico; and they are also excluded even from the ports not blockaded in possession of Mexico; whereas the new system would soon open to our commerce all the ports of Mexico as they shall fall into our military possession.  Neither our own nor foreign merchants are required to send any goods to Mexico, and if they do so voluntarily it will be because they can make a profit upon the importation there, and therefore they will have no right to complain of the duties levied in the ports of Mexico upon the consumers of those goods—­the people of Mexico.  The whole money collected would inure to the benefit of our own Government and people, to sustain the war and to prevent to that extent new loans and increased taxation.  Indeed, in view of the fact that the Government is thrown upon the ordinary revenues for peace, with no other additional resources but loans to carry on the war, the income to be derived from the new system, which it is believed will be large if these suggestions are adopted, would be highly important to sustain the credit of the Government, to prevent the embarrassment of the Treasury, and to save the country from such ruinous sacrifices as occurred during the last war, including the inevitable legacy to posterity of a large public debt and onerous taxation.  The new system would not only arrest the expensive transfer and ruinous drain of specie to Mexico, but would cause it, in duties and in return for our exports, to reflow into our country to an amount, perhaps, soon exceeding the $9,000,000 which it had reached in 1835 even under the restrictive laws of Mexico, thus relieving our own people from a grievous tax and imposing it where it should fall, upon our enemies, the people of Mexico, as a contribution levied upon them to conquer a peace as well as to defray the expenses of the war; whereas by admitting our exports freely, without duty, into the Mexican ports which we may occupy from time to time, and affording those goods, including the necessaries of life, at less than one-half the prices which they had heretofore paid for them, the war might in time become a benefit instead of a burden to the people of Mexico, and they would therefore be unwilling to terminate the contest.  It is hoped also that Mexico, after a peace, will never renew her present prohibitory and protective system, so nearly resembling that of ancient China or Japan, but that, liberalized, enlightened, and regenerated by the contact and intercourse with our people and those of other civilized nations, she will continue the far more moderate system of duties resembling that prescribed by these regulations.
