In the meantime the Mexican Government monopoly in tobacco, from which a considerable revenue is realized by Mexico, together with the culture there which yields that revenue, should be abolished, so as to diminish the resources of that Government and augment our own by collecting the duty upon all the imported tobacco. The Mexican interior transit duties should also be abolished, and also their internal Government duty on coin and bullion. The prohibition of exports and the duties upon exports should be annulled, and especially the heavy export duty on coin and bullion, so as to cheapen and facilitate the purchase of imports and permit the precious metals, untaxed, to flow out freely from Mexico into general circulation. Quicksilver and machinery for working the mines of precious metals in Mexico, for the same reasons, should also be admitted duty free, which, with the measures above indicated, would largely increase the production and circulation of the precious metals, improve our own commerce and industry and that of all neutral powers.
In thus opening the ports of Mexico to the commerce of the world you will present to all nations with whom we are at peace the best evidence of your desire to maintain with them our friendly relations, to render the war to them productive of as little injury as possible, and even to advance their interests, so far as it safely can be done, by affording to them in common with ourselves the advantages of a liberal commerce with Mexico. To extend this commerce, you will have unsealed the ports of Mexico, repealed their interior transit duties, which obstruct the passage of merchandise to and from the coast; you will have annulled the Government duty on coin and bullion and abolished the heavy export duties on the precious metals, so as to permit them to flow out freely for the benefit of mankind; you will have expunged the long list of their prohibited articles and reduced more than one-half their duties on imports, whilst the freest scope would be left for the mining of the precious metals. These are great advantages which would be secured to friendly nations, especially when compared with the exclusion of their commerce by rigorous blockades. It is true, the duties collected from these imports would be for the benefit of our own Government, but it is equally true that the expenses of the war, which Mexico insists upon prosecuting, are borne exclusively by ourselves, and not by foreign nations. It can not be doubted but that all neutral nations will see in the adoption of such a course by you a manifestation of your good will toward them and a strong desire to advance those just and humane principles which make it the duty of belligerents, as we have always contended, to render the war in which they are engaged as little injurious as practicable to neutral powers.
