The four important conventions signed at the Fourth Pan American Conference at Buenos Aires, providing for the regulation of trademarks, patents, and copyrights, and for the arbitration of pecuniary claims, have, with the advice and consent of the Senate, been ratified on the part of the United States and the ratifications have been deposited with the Government of the Argentine Republic in accordance with the requirements of the conventions. I am not advised that similar action has been taken by any other of the signatory governments. INTERNATIONAL ARRANGEMENT TO SUPPRESS OBSCENE PUBLICATIONS. One of the notable advances in international morality accomplished in recent years was an arrangement entered into on April 13th of the present year between the United States and other powers for the repression of the circulation of obscene publications. FOREIGN TRADE RELATIONS OF THE UNITED STATES. In my last annual message I referred to the tariff negotiations of the Department of State with foreign countries in connection with the application, by a series of proclamations, of the minimum tariff of the United States to importations from the several countries, and I stated that, in its general operation, section 2 of the new tariff law had proved a guaranty of continued commercial peace, although there were, unfortunately, instances where foreign governments dealt arbitrarily with American interests within their jurisdiction in a manner injurious and inequitable. During the past year some instances of discriminatory treatment have been removed, but I regret to say that there remain a few cases of differential treatment adverse to the commerce of the United States. While none of these instances now appears to amount to undue discrimination in the sense of section 2 Of the tariff law of August 5, 1909, they are all exceptions to that complete degree of equality of tariff treatment that the Department of State has consistently sought to obtain for American commerce abroad. While the double tariff feature of the tariff law of 1909 has been amply justified by the results achieved in removing former and preventing new, undue discriminations against American commerce it is believed that the time has come for the amendment of this feature of the law in such way as to provide a graduated means of meeting varying degrees of discriminatory treatment of American commerce in foreign countries as well as to protect the financial interests abroad of American citizens against arbitrary and injurious treatment on the part of foreign governments through either legislative or administrative measures. It would seem desirable that the maximum tariff of the United States should embrace within its purview the free list, which is not the case at the present time, in order that it might have reasonable significance to the governments of those countries from which the importations into the United States are confined virtually to articles on the free list.
