The President to the Secretary of the Treasury .
Washington , October 19, 1915 .
My Dear Mr. Secretary: I am informed by the Department of State that the recognized de facto Government of Mexico is now in effective control of all the ports of entry in Mexico, except those along the international boundary in the States of Chihuahua and Sonora and all the ports in Lower California.
As an exception to the embargo placed on the exportation of munitions of war to Mexico by the President’s proclamation of October 19, 1915, you will please instruct the collectors of ports and other officers of the Treasury Department to permit to be exported through the United States Custom Houses munitions of war for the use of the recognized de facto Government of Mexico or for industrial or commercial [Page 782]uses within the limits of the territory under its effective control as above set forth. This exception, however, shall not apply at the present time to shipments into the States of Chihuahua and Sonora, and into the Territory of Lower California, and you will so instruct the appropriate collectors of customs and other officers of the Treasury Department.
